Re: [DUG] ChCh Update

[Conor Boyd]

I have. ;-)


Thanks Malcolm, appreciate your thinking of me.

 

We’re in Huntsbury (or Muntsbury as it’s now called), and while we’re maybe not 
as bad as Mt Pleasant and further round, we’re on the rock too and much worse 
hit this time than last time.  Roger Sutton of Orion lives nearby and somebody 
yesterday told me most of his area (Glenelg Spur, Rapaki) is a total write-off.

 

I’ve moved the family out to Castle Hill, kids going from a badly damaged 
school in St. Martins of 470 to the local school in Springfield a 1/10th the 
size of that one, so that’ll be an experience for them.  We only got power on 
mid-last week, and water yesterday, our house has moved 20mm on it’s 
foundations/piles, the chimney has fallen into the dining room, and the kitchen 
ceiling is collapsing.  But still, as Peter’s email said, there are a lot of 
people a lot worse off than most of us.

 

Thoughts with them, especially with these last 2 colder nights.

 

Only back to work today, and have had no TV and precious little interweb access 
for the last 2 weeks, so I have a bit of catching up to do.


Take care, all.

 

Cheers,

 

Conor

Re: [DUG] Variabels stored

[Conor Boyd]

Probably as a field on the form class that you're dealing with.
 
e.g.
 
type
TWallaceForm = class(TForm)
  btnOK: TButton;
...
  txtWallacesHiddenTextBox: TEdit;
...
private
  FWallacesPrivateVar: string; // use this instead of your
hidden text box.
// Can create as
many variables (or fields as they're known in Delphi parlance, hence
the F prefix)
// of as many
different types as you like.
...
end;
 
Hope I've understood what you're asking for correctly.

Re: [DUG] Automatic build process

[Conor Boyd]

I use CruiseControl.NET (http://ccnet.thoughtworks.com/) which executes
fairly extensive NAnt (http://nant.sourceforge.net/) scripts which deal
with the invocation of the Delphi command line compiler.

My scripts also go further and automate the use of Installshield etc to
build installers, etc.

I'm not quite sure why you might have errors that you can't fix.  Can
you give some more detail?

Happy to answer more questions on our setup if it's helpful.

What do people use to automate their build processes.  I have multiple
delphi group projects that I build but the issue is that on some of the

tools that I can work around these errors with.  The idea will be to

Hi all.
Dont get me started on why we have to use faxes but we have to.

Heres the issue. we are using the AsyncPro fax controls (in Delphi 2010)
to send faxes. It all works well, EXCEPT, if we add an area code on to
the recipients phone number, say 033539901 (with 1, for the dialing
prefix) the fax machine rings, it answers, but refuses to accept the
fax.
if I strip out the 03 (still using the 1, for the dialing prefix) it
works fine 
Now if its local numbers we were using then no prob, but we are going to
have to send to another town.

Has anyone see this before or have any suggestions?

Re: [DUG] Icon

[Conor Boyd]

My take on this would be these are just resampling artifacts.  Different
sampling algorithms (of which Irfanview provides quite a few) may well
give different results.

If you've got a simple graphic like you describe, I would suggest
decreasing the colour depth to e.g. 16 colours prior to
resizing/resampling, and then you shouldn't find you get subtle
differences in e.g. blue.

Other than that, the resampling results you describe are exactly what I
would expect from a photographic image-manipulating program like
Irfanview (I would content that Irfanview is for manipulating images,
not necessarily graphics - they're different beasts).  I wouldn't expect
Sharpening to solve the problem.  When one talks about sharpening an
image it's probably exactly what you in particular don't want -
sharpening makes the dark side of an edge subtley darker, and the light
side lighter; that's what sharpening means in image-manipulating terms.

In summary I would disagree that this is in any way a problem with
Irfanview and it's ilk, but more a matter of expectations.

Hope this helps,

C.

On Behalf Of John Bird

The only problem I have struck with Irfanview (and other programs) is in
resizing images:

If I have an image I want to use, I will usually resize it to several
different sizes, some small enough to be used as images on a TBitButton.

If for example the image is Blue, and has a transparent (eg white)
background and is resized smaller, there are a few pixels on and around
the edge of the blue image on the background that get to be averaged to
a light 
blue - in between white and blue.   This is not a problem until the
image is 
shown on a darker background, and the light blue pixels show as a small
ragged bright edge to the image because they are not the transparent
colour any more.

I have experimented with the IrfanView  option Sharpen after resize
but this does not quite solve the problem - it seems to sharpen the edge
of bright pixels, and sometimes introduces other oddities.

Anyone else have a way to deal with this?   I have often blown up the 
resized image using Photofiltre (ie view at 800%) and carefully brush
the 
offending edge pixels back to the transparent colour.   Very fiddly!

John

any programs started by that user do not get administrative rights

I am pretty certain that 30/12/1899 is a unique start point for Delphi -

other systems (Unix and Windows) look to start at 1970 or 1980.   I am

something similar to a file datestamp - FileDatetoDateTime and/or
FileTimeToSystemTime API

I released a new version of my software using the TCP server/client
method to communicate with a separate elevated app where I do my HKLM
writing etc.  But this is turning out to be a nightmare with firewalls.

 

The proper method is to write a DLL which does something to trigger
elevated privileges.  I'm hoping someone could send me example DLL code
I can use to do this, and the code to call it from my app.  I'm not
experienced writing and using DLL's.

begin
ComboBox1.Clear;
ComboBox1.Items.AddObject('All Locations', TObject(-1));
ComboBox1.Items.AddObject('Only this Location', TObject(0));
ComboBox1.Items.AddObject(Test Location', TObject(1));

i := Integer(ComboBox1.Items.Objects[0]);
showmessage(inttostr(i));
end;

When I tried to run this code in Delphi 6 and Delphi 2007 , I am getting
List Index out of bounds[0] error in Showmessage. When I tried -2, -3,
-4... instead of -1 object , I got the proper output without any 
List index out of bounds error. Also I am getting -1 without any error

Is it a bug in latest version of Delphi ? Any help is appreciated.

Re: [DUG] Apple iPad - OT

Speaking as a cyclist as well as a car-driver, I mostly agree with you,
hence my mention of tolerance from both sides, and my reference to the
small minority of cyclists was basically to the type of cyclist you talk
of.
 
As a commuter cyclist though (and not really one of the lycra jockeys),
I receive a fair share of abuse from car drivers who tar all cyclists
with the same brush, e..g you cyclists just think you own the road.
Sure, some of them wrongly do, but I'm not some cyclists; I'm just one
guy who tries to respect the road rules, stops at red lights, doesn't
ride on the pavement, wants to get home to his family at the end of the
day, and doesn't appreciate getting cut up unnecessarily.

Some people don't seem to be able to differentiate.

To be honest, I seem to have more trouble with bus-drivers than
car-drivers... ;-)

Hi Kyley,
 
Thanks, although I was asking John for an example of his concern. ;-)
 
I've used Graphics32 previously to resize images with Lanczos Kernel
resampling etc myself (see the screenshots on http://gloss.ildica.com/
to see what I use it for), so I know how to resize images properly while
maintaining quality.
 
I just wanted to see an example of what was bothering John because
personally I don't have any problems resizing images either in code or
using tools such as Irfanview (I'm a photographer as well, so I know a
fair bit about image sharpening etc too).

Re: [DUG] Resizing images

[Conor Boyd]

What I think you're seeing (without seeing your example) is the softness
introduced by most resampling algorithms (when used for downsampling).

Something like Bicubic Sharper in PS or Lanczos Kernel in Irfanview
might help.

However, most of these sharpening algorithms probably work better on
photographic images than they will on graphics.  Maybe a more dumb
program like Paint would resample a graphic better.  Or reducing the
color depth of the image before resizing will also help.

Post an example, and I'll see what I would do with it.

Re: [DUG] Resizing images

[Conor Boyd]

What I have just tried is this:

Open your double image in Irfanview.
Crop it to the left hand image.
Open the Resize/Resample dialog.
Choose to resize it in half.
Choose to Apply Sharpen after resample.
Choose to Resample using Lanczos Kernel.

Voila, it looks pretty good to me.

The main point here is probably resampling, not resizing.

You can see the ragged border when the image is on a darker background,
as the offending pixels are not the same as the transparent colour of
the rest of the square image out to the edges - they have been altered
in colour by 
the resizing.   Hope I am making sense.

The original image was a png, and it has been resized then converted to
BMP using Irfanview. As far as I recall I didn't use the Lanczos option,
just the defaults.

If you want to to use shared memory in Vista and above its best to write
a service to create global shared memory that all users can access. The
key here is global shared memory and with the right security bits set.
Best to Google global shared memory for more info.

Re: [DUG] OT : GoogleWave invites

[Conor Boyd]

Basically Google's thoughts on what email (or rather a collaboration
tool) should be if email was being designed from the ground-up today.
 
It's like a mixture of email and instant messaging, so multiple people
can be collaborating on a wave together, in real-time.
 
The Lifehacker guys have a comprehensive website about it here when
you're back online: www.completewaveguide.com
 
Still in early beta.

I'm really not sold on the VCLX project. I will concede that my attitude
is in part based on my memory of the Kylux and .NET disasters which were
admittedly with Borland rather than Embarcadero. However I just don't
see that it is possible to produce a really excellent cross platform
version of Delphi in 18 months. Maybe by VCLX version 2 or 3 it will be
reasonable but even then my understanding is that most existing
development projects (ie any using significant GUIs with third party
components, such as ours) will have no chance of moving to the cross
platform VCLX.

 

We don't have any real need for 64 bit compilation either yet BUT at
least it seems like a logical progression of core Delphi and is
something we will definitely want in the future. VCLX seems like a
massive detour (yet another VCL version!) and a likely waste of
resources rather than an improvement to core functionality.

 

From what Malcolm says though I'm in the minority. I'm surprised but it
wouldn't be the first time ;-).

 

I guess we will see how it pans out.

I think a lot of you are being short sighted.  Just my opinion.
 
I lived through the mini-computer era, using Digital Equipment
mini-computers with RT-11 and VMS - both really good operating systems,
and thought at the time if they started selling VMS for a few $100
rather than thousands they may have captured the mini-computer market as
it was way superior to MS-DOS, instead they didn't adapt and got
clobbered by Microsoft to the extent the company and the platform does
not even exist now.
 
Its a less certain thing as its still the future, but its my guess
likely in 5 years netbooks/laptops and mobile and phone OS will largely
kill desktop PCs and in time likely Windows too, as there is not much
sign they will be the leading candidate for mobile devices in 5 years.
Hence the more cross platform and new UI (read touchscreen) enabled a
language is the better positioned it will be.
 
Also apps are moving more to be web enabled, where the UI is done by the
browser instead, so this also is not really tied to one OS.  There are
only a few good frameworks that run across many OS's - think
Firefox/Thunderbird (XUL) and Safari/Itunes etc.  As far as I can gather
none of these are remotely easy for new programmers to jump into.
 
Thats why I reckon Delphi as a cross platform simple UI language could
be a killer, and why its worth doing even if it is not too easy.

Re: [DUG] tricky event question

The way you've described it smells a bit to me.  Why do you need to
free the combobox?  Why not just hide it or something similar?

However, if you truly want to do it, look into posting a message to the
form using PostMessage, and then handle the message on the form, and
free the combobox at that point.

I have a combobox with an event (onChange) that refreshes the display.  
As part of that refresh the combobox is freed.  This causes an AV as the

What would be the best way of dealing with this scenario?

Re: [DUG] Image manipulation

[Conor Boyd]

I've used a mixture of GraphicEx and Graphics32 for a Delphi screensaver
I've written (http://gloss.ildica.com) which can handle most of those
formats, plus high-quality resampling/resizing and saving, so yeah, it's
possible.

IIRC I use GraphicEx for actually knowing how to load various image
types and then assign the image to a Graphics32 object for resampling
etc before saving.

http://www.graphics32.org/wiki/

It's open-source, works well for me under D2007, dunno about any later
versions.

If you have specific questions about using it for resampling, drop me a
line, and I'll look some code out.

No I was not a problem at the Delphi launch.  One pointed and tongue
in cheek observation w.r.t the fact that the Project Options dialog does
not itself make use of the much vaunted checkbox property editor for
boolean's does not amount to a problem in my book.

 

No, Richard for some reason chose to single me out as unfriendly and
unhelpful specifically w.r.t my contribution to this list.

 

It is fair to say that I have taken deep, DEEP offence at that, being
among what I consider to be among the most strenuously helpful and
polite (not to mention trying to straighten out misunderstandings
between others who perhaps have not been so helpful or friendly - not
naming names, but shall we just say that those choosing to reside in
glass houses should not be so quick to throw stones).

 

Suffice to say that any further software purchases that I personally
make shall not contribute to any swelling of Developers-Inc coffers.  I
see no need to be helpful in THAT direction at all.

 

It didn't help - although not directly connected - that presumably for
some other reason Malcolm Groves neglected to mention that it was my
comment on his blog that prompted him to have the conversation with
Chris Bensen (to whom I'd already put the idea, via his blog) about
directly supporting for Synaptics devices in the touch/gesturing engine

Re: [DUG] Image manipulation

[Conor Boyd]

Yeah, those issues are what drove my choice of Graphics32 (image quality
and scaling).
 
Here's some code which uses Graphics32 to resample an image.
 
OldBitmap, TempBitmap are of type Graphics32.TBitmap32
NewBitmap is of type Graphics.TBitmap;
 
  OldBitmap.Assign(a regular Graphics.TBitmap here which you could load
using GraphicEx);
 
  TempBitmap := TBitmap32.Create;
  try
TempBitmap.Width := Trunc(OldBitmap.Width * Scale);
TempBitmap.Height := Trunc(OldBitmap.Height * Scale);
 
rs := TKernelResampler.Create(OldBitmap);
 
if FastResamplingWanted then
  rs.Kernel := THermiteKernel.Create
else
  rs.Kernel := TLanczosKernel.Create;
 
GR32_Resamplers.StretchTransfer(TempBitmap,
Rect(0, 0, TempBitmap.Width,
TempBitmap.Height),
Rect(0, 0, TempBitmap.Width,
TempBitmap.Height),
OldBitmap,
Rect(0, 0, OldBitmap.Width,
OldBitmap.Height),
rs, dmBlend, Nil);
 
NewBitmap.Assign(TempBitmap);
  finally
TempBitmap.Free;
  end;

I've paraphrased this from some code of mine, but hopefully that's the
gist of a high-quality resample for you using Graphics32.

Re: [DUG] Image manipulation

[Conor Boyd]

Depends what Robert wants, but StretchDraw won't give you anything like
the resampling quality of a decent resampling algorithm such as a
Lanczos Kernel.  If you want to see the difference without writing code,
check out the freeware Irfanview image utility (www.irfanview.com) and
try resizing an image using the various resampling algorithms available
in that utility.
 
One thing that I think a lot of people overlook is that a file format is
just that: a file format.  Once one has loaded an image from a file of a
particular format, then the image in memory is simply a bitmapped image
(or a raster image or whatever).  At that point, it's completely
divorced from the file format it happened to be last persisted in.

The trick is that you can resize as a BMP, but save back as a JPG
 
Can email the rest of the project, but here is the main unit to show its
not hard to do...
 
This program zooms a bevel in and out to show the size of the image will
be when resized, but does not actually resize until you click resize
now, as the image would lose quality by being continuously resized.
 
Its all done by about 4 lines in the ResizeNow procedure

Re: [DUG] registry caching?

Which OS?

I hope someone can help.

I have an app where the installer sets an XP compatibility mode registry
entry during installation.  Don't ask why but it is generally required.

As the app loads after installation, it checks some hardware
requirements to see if XP compatibility mode needs to be switched off.
If so, the registry entry is deleted and the program then needs to be
restarted, which I want to do automatically.

I have a helper app which I load just before terminating the main app.
The helper app then reloads the main app after a 2 second sleep.

However, the result is that the program is still loading in
compatibility mode even though the registry entry is deleted well before
it loads.
 
I have LazyWrite disabled on the registry change, so it is instantly
updated.  I tried a massive 15 second sleep in the helper app, so the
main app is closed for 15 seconds before reloading, yet it still loads
as if the registry entry is still there.

If I terminate the app and load it manually, then it's always correct!
I don't understand this.  Why would loading the app manually be any
different to loading it from another app?

I'm using CreateProcess with CREATE_NEW_PROCESS_GROUP to load the helper
app and to load the main app again.  I tried ShellExecute with no
difference.

Is there some way to make this work automatically?

The only method I can adopt at this stage is to popup a message to ask
the user to load the program manually, which is not user friendly.

Many thanks,
Ross.

Re: [DUG] registry caching?

[Conor Boyd]

I've only recently had the pleasure of really getting to grips with
UAC, etc, so if I'm telling you stuff you already know, forgive me.
It does sound like this is a UAC or elevation issue.

When you say raised privileges, do you mean elevated?  You app
either runs elevated or it doesn't.  Installers by default run elevated,
hence the UAC prompt when you start an installer.

If your installer writes to HKLM for example, it will be writing to the
real HKLM as opposed to a virtualised one.

I'm still unclear as to whether your app will be running elevated.  If
it's not running elevated and e.g. tries to write to HKLM, it will be
writing to a virtualised copy of the registry.  If it writes it's own
value to it's virtualised copy of the registry, then you can change the
real HKLM value to your hearts content, but your app will never see
those changes, since it will only see it's virtualised copy.

Like I said, this still smells like a registry virtualisation issue to
me.

However, if it's not HKLM keys (or other UAC-restricted territory such
as Program Files) we're talking about anyway, then I'm a bit stumped,
sorry. ;-)

Sorry, I should have mentioned it is Vista, but it'll be the same issue
with Win7.  It's not a virtualization issue.  This is all done with
raised privileges during and immediately after installation.

It seems to be caching the compatibility setting somehow.  Or perhaps
the helper app is inheriting the setting and then inheriting it back to
the main app when it restarts it.  It would appear a very stupid thing
for Windows to do if that is the case, but I'll test it to be sure.

Re: [DUG] registry caching?

[Conor Boyd]

A process either runs elevated or it doesn't.

A process cannot change from an unelevated state to an elevated one.

A process can request to spawn an elevated sub-process in which case the
UAC prompt will be shown.  Or it can request an elevated instance of a
COM server in which case the UAC prompt will be shown.

In the second scenario, if the process holds on to that COM object for
the rest of the process's lifetime, then it won't cause the UAC prompt
to be shown again.

To give an example of the second scenario, I have a legacy app that
writes to HKLM (on which other parts of the program suite rely).  I
pulled the HKLM-writing code out into a COM server.

My legacy app (when running on Vista or Win 7) requests an instance of
the new COM server, at which point the UAC prompt is shown.  If the UAC
prompt completes successfully (either because the program was being run
by an admin who confirms the elevation, or an admin username/password
combo is correctly entered) then my legacy app holds on to that COM
server instance for the rest of the session to enable continued
successful HKLM writing without further UAC prompts.

One can google for the circumstances under which Vista will determine a
program to be requiring elevation up front (these include having the
word setup in the filename, which is how most installers automatically
request elevation on startup).

Or one can include a Vista manifest indicating the elevation status that
the application requires.  If you set it to requireAdmin, then the app
will always present a UAC prompt on startup, and won't continue without
successful completion of that UAC dialog.

An installer isn't an installer from the POV of Vista/Win7.
Installers are simply examples of programs which Vista always runs
elevated.

I could well be wrong, but I don't believe Windows controls or monitors
the scope of elevation timespans as you suggest John.  I believe it's
simply a question of each application determining it's own elevation
status (through manifests, etc) and controlling the elevation status and
lifespan of any child-processes or COM objects that it instantiates.

Cheers,

Conor

I have noticed that it must store the process ID or something similar of
the original parent process  that needed and was granted the elevation.
If the same action requiring elevation is run again it does not ask as
long as the original program or one started by the original program is
still running and 
repeating the same action.   However if the program is terminated and 
restarted it does ask again.

It shows there was some thought by MS into giving the elevation some
scope over actions and processes related to the original process, and
probably for some time as well, all of which is sensible.

(In my case it was not registry stuff, but a starter program copying
.Exe files wich does trigger Vista into thinking its some kind of
installer I am guessing - which is similar to what you are doing)

Re: [DUG] registry caching?

[Conor Boyd]

Hmmm, I'm a bit stumped then.

Have you checked in the virtualised part of the registry to see if there
are any rogue keys in there that you're not expecting?  I appreciate you
obviously don't expect there to be, especially given the way you
describe the real key successfully disappearing...

E.g. under something like (the SID is obviously dependent on the user
under which the processes are running):
HKEY_USERS\S-1-5-21-583907252-1580818891-839522115-6268\Software\Classes
\VirtualStore

Cheers,

On Behalf Of Ross Levis

I do mean elevated.  I do all HKLM registry changes in a separate little
app which has a manifest which specifies that it requires elevated
administrator privileges.  Not the official way to do things but it
works.  It will ask for the UAC prompt if I run it manually.  

But since the installer is elevated and it loads the app after
installation, it also gets the elevated rights by default.

So that's not the problem.  I am looking at the registry using regedit.
During installation I can see the HKLM key appear in regedit.  My app
then loads, and I see the registry key deleted by my app.  It is
definitely gone.

My app then loads my little helper app and the main app is terminated.
No matter how long the helper app sleeps before loading the main app
again, the registry setting is still taking effect.
 
Vista doesn't look in virtualized areas for the AppCompatFlags, so it
must be some sort of caching.  What is strange is if I disable the main
app from loading the helper app, so my main app just terminates and
doesn't get reloaded, and I then manually load my app from the installed
icon, it works correctly.  I don't think virtualization would explain
that either.

I'm guessing it would work if I set the Windows Task Scheduler to load
my app in 5 seconds, but that seems a lot of work.

The only logical thing I can think of is there must be some information
being transferred when loading one program from another.  Certainly
elevated privileges is one thing that is transferred in this situation.

Perhaps another way around it is to load both the helper app and main
app from the installer so they are loaded without any obvious link to
each other.  The helper would then need to monitor the main app to see
when it is terminated, before restarting it.  Could be worth a try when
I get time.

Cheers,
Ross.

Is there any problem with a Boolean returned from Win32 routines?

The real question though is how much benefit you actually got from that
extra 0.5 - 1GB ?

 

I'm guessing not much.  Not really.  But if you've got a system equipped
with 6GB or 8GB... at that point 64-bit makes perfect sense (and if
you're the sort of user that is loading a 4GB system so heavily that the
extra 0.5-1GB *does* make a difference, you're probably the sort of user
that would like 6-8GB of RAM anyway and you've already long since moved
on to 64-bit).

 

But at 4GB I really don't think there's much in it, so whilst there may
not be a specific reason to use 32-bit, there's also no great compelling
reason to use 64-bit either, and a few *potential* reasons not to (lack
of 64-bit support for XYZ, where XYZ varies from individual to
individual) potential complications when running (some) 32-bit software
etc etc.

aiui if you've only got 4GB of RAM then I don't think 64-bit is going to
make that much of a difference.  Of course, if you have the capacity to
go beyond 4GB of physical RAM and the intention to do so, then 64-bit
might be worthwhile.

Thanks for those suggestions, Todd.

Still struggling a bit with it, but that's been useful.

Hi Conor

Check out this link

Have you considered using h2pas in Free Pascal?
or
SWIG for Delphi

 I'm needing to call a Windows API function introduced in Vista from my

 Delphi app, but I don't have any Delphi headers which describe the 
 function.
 
 Related functions are already documented in the JEDI Windows API 
 library, but not this function.
 
 My C++ is almost non-existent, and I'm struggling to work out the 
 Delphi definitions that correspond to the function and it's parameter 
 as documented on MSDN.

Hi guys,

Just to clarify, we're not doing cross platform and then Win64, we're
doing them in parallel (one of the benefits of an increased RD budget
under Embarcadero). Cross platform will make it to market earlier
however.

Mike Swindell covers it more in a comment on Marco's post here
http://blog.marcocantu.com/blog/delphi_cross_platform_anderson.html :

Crossplatform and 64bit are two separate projects running in parallel.
64bit is moving fast but will take longer to get to market than xplat.
64bit has many implications on the existing customer Delphi and VCL
Windows codebase. xplat is certainly a lot work (new compilers and VCL
framework) but has a different type of of impact and expectation on
existing code bases. ie we're more free to make breaking changes when
going cross platform than 64bit. 

I get that it's disappointing to some people, that's unfortunate, and we
looked long and hard at how we could do this any other way.
Unfortunately but any major roadmap decision is likely to be make some
people unhappy. We'll get them both out as soon as we can.

Cheers
Malcolm

It had already been referred to elsewhere in the discussion as GExperts.

Re: [DUG] Detecting screensaver

[Conor Boyd]

Wouldn't surprise me if the preview button doesn't exhibit the same
behaviour.

Screensavers have to be written to respond explicitly to being run in
preview mode (they basically have to parent themselves to the window
handle of the preview window which is passed to them when they're
executed in Preview mode).

I believe your test is the correct approach, John (as backed up here:
http://stackoverflow.com/questions/510734/how-to-determine-that-a-screen
saver-is-running and with my own experience of writing a screensaver in
Delphi).

Rather than using the Preview button, you could easily rustle up a
little utility to kick the screensaver into life by broadcasting the
appropriate window message:
  Perform(WM_SYSCOMMAND, SC_SCREENSAVE, 0 );

HTH,

Conor

I have seen that variant, but from what I saw this detects the
screensaver is set, not that it is active?

From the D7 win32 help:

SPI_GETSCREENSAVEACTIVE Determines whether screen saving is enabled.
The pvParam parameter must point to a BOOL variable that receives TRUE
if enabled, or FALSE otherwise.

In my tests the above always returns true, as I do have a screen saver
enabled, and it does not return a changing status if the screen saver is
on at the moment or not. (I was using the control panel screen saver
preview button to check this).

I am trying to detect if a screensaver is currently actually running

 I'm using SystemParametersInfo(SPI_GETSCREENSAVEACTIVE, 0, 
 @ATScreenSaverOn, 0); It works on Vista here

 SystemParametersInfo(SPI_GETSCREENSAVERRUNNING, 0, @ATScreenSaverOn, 
 0);

 Note this is documented as Windows 95 only, which I am guessing why 
 it doesn't work (XP/Vista)

 The only other way I can think of is to try to find the full name of 
 the foreground program and see if it has a .SCR extension, but I am 
 not confident that would work.

Re: [DUG] Detecting screensaver

[Conor Boyd]

Re-reading this, I may have been getting confused between the little
preview window and hitting the preview button.

Regardless, it still wouldn't surprise me if a screensaver running from
the Preview button doesn't exhibit the same behaviour.  For example,
when I hit the Preview button on my work PC, my desktop doesn't get
cleared when the Preview runs.  My desktop does get cleared when the
screensaver is truly running.

Re: [DUG] Everyone aware of the Delphi roadmap presentationon 27thmay?

Hi Malcolm,

Thanks for kicking this series off for us, good to see it happening.

I didn't really have any issues with audio (dropped out for the odd
second here and there, but each drop-out was short enough that the
sentence was still understandable).  I thought it went very smoothly.

I'll look forward to seeing what other topics come up.

Personally, I still don't see what All Access has to offer my team, and
from that POV, my eyes glazed over for what seemed like the half of
Wednesday's webinar this week that was all 3 of the presenters pushing
All Access.  I appreciate others mileage may vary... ;-)

Regardless, please keep the webinars up; they're good to see.

Cheers,

Conor

Thanks Leigh,

Glad to hear it was useful. I've got some feedback from a few people on
a couple of issues that we'll try and tighten up for next time. Did you
get the audio ok? That seems to have been an issue for a couple of
people.

We're planning/hoping to do a webinar every Wednesday at the same time.
This was the first, next week we have one on Database Performance
Optimisation, the one after that is an All Access overview. I'm
finalizing the topics/speakers for the next 6 weeks or so at the moment
and will hopefully publish them soon. I'm trying to get one during June
that covers the issues involved with bringing old code forward to the
Unicode VCL. Any other topic requests, let me know.

They will all be recorded and posted into a central place on the
Developer Network. I'll post a link once I have the recording from last
Wednesday's up there.

Cheers

Hi all.

Is there a way to capture outputDebugString other than using the
EventLog?
The EventLog is fine, UNTIL, you want to copy an output, so I thought I
might write my own little capture tool.

Anyone done/seen anything like this?
I assume since its an API call I just need to listen to a message?

 Hi all.

 Is there a way to capture outputDebugString other than
using the
 EventLog?
 The EventLog is fine, UNTIL, you want to copy an output, so I
thought I
 might write my own little capture tool.

 Anyone done/seen anything like this?
 I assume since its an API call I just need to listen to a
message?


 Thanks, Jeremy

Unfortunately the only way you can become a senior developer is by
providing this user group with a copy of your birth certificate. Only
after the group agrees that you are at least 70 years old can you start

[DUG] Elevating Delphi code in Vista

[Conor Boyd]

Hi all,
 
I'm about to pull a chunk of code out of my Delphi app and bundle it
into another binary so that I can elevate that chunk of functionality on
Vista, while leaving the main app running unelevated.
 
I've seen a number of references to the blog posting linked below which
I can't get access to (when I visit it, it says I haven't been invited
to read that blog).  I believe this article to be describing how to
package this code up into a COM DLL and elevate my administrative
functionality that way.
 
http://developersoven.blogspot.com/2007/02/leveraging-vistas-uac-with-de
lphi-part.html
 
Can anybody here provide more information on this process?  I know how
to write COM DLLs no problem, but I'm unsure about whether there are
other issues involved here?
 
Or does anybody have an alternative suggestion for functionality
requiring elevation on Vista?  The other alternative I've got is just to
bundle my code into a simple executable with an elevated manifest
resource compiled into it, and simply ShellExec that.
 
(The functionality in question is simply writing value(s) to our key
in HKLM in the registry).
 
Thanks,
 
Conor

Re: [DUG] Elevating Delphi code in Vista

[Conor Boyd]

Thanks for the pdf link Rob, that's very useful.
 
The main issue I'm trying to work out is our registration of users
authorised to use our software.  This writes some registration keys
into HKLM.  Currently, on Vista, due to the registry virtualisation that
happens for unelevated apps, each user only succeeds in registering our
software for themselves, rather than for anyone using the PC.
 
I don't think I've got my Google search terms quite right, because I've
been struggling to find the details on the COM option.
 
Thanks,
 
C.

running on Vista was pretty straight forward EXCEPT that it didnt like

was fine.

On that not, anyone tried Windows 7 yet? I am liking it so far.

Re: [DUG] [OFF-TOPIC] memory issues

[Conor Boyd]

For testing on slower PCs, here's one thought of mine.
 
I use VirtualPC for doing a lot of testing.  While I accept it's
difficult to quantify how much slower a VPC is rather than my desktop,
it is most definitely slower.  Plus you have the ability to control the
memory available to the VPC.
 
Using Virtual Server would probably give you even more control, since
you can throttle the processor availability for a VPC as well.
 
As well as VirtualPC for testing on my dev box, I use virtual machines
on a Virtual Server for build PCs, etc.  The change to the Delphi
license a couple of versions ago just made that scenario more legit. ;-)

I agree Kyley, you do need to re-invest in your Hardwarebetter you
have it than the taxman take your $$but there is one thing that you
need to keep in mind.
Whilst your software runs at an amazing pace on your PC, the customer
may not have such a speedy machine and your software may run like a
one legged dog.
If you are developeing for a single client you can say go update
your hardware, but when developing for a mass-market (well as mass as
you can get in NZ) you may have people trying to run your kick-ass
software on a PIII 700 or something.
I always try to take this into consideration, and hence why I still ahve
a 3year old PC. If it flys on my machine I have written nice-ish tight
code and it will be fine on other PC's.
However, when customers have better machines than you, its time to do
some investment :-) Which is what I am doing at the moment. I just have
to decide what to get.!

As for 2 monitors, I tried that a few years back, but I have to say it
just annoyed me, so I have go back to a big single monitor. I guess its
about what works for me and I know others will say its mad, bit honestly
it doenst bother me having 1 monitor.

I think with 2 30 inch screens you'd get neck strain.  I've
heard of
people having a 30 inch screen and two smaller screens rotated
either
side (so that their width matches the height of the big screen)
- which
means that you don't have a gap directly in front of you.

I have a 26 inch screen at home and this was as large as I could
justify
to myself for the price.  It has a 21 inch CRT beside it, but I
haven't
felt the need to use it for awhile (not doing much coding on

a question about multi monitors - as the help is a bit vague about the
form property Position.  In D7, D2007 there are these 2 options:
 
poDesktopCenter
poScreenCenter
 
from the help:
 
poScreenCenter The form remains the size you left it at design time, but
is positioned in the center of the screen. In multi-monitor
applications, the form may be moved from this center position so that it
falls entirely on one monitor, as specified by the DefaultMonitor
property. 
 
poDesktopCenter The form remains the size you left it at design time,
but is positioned in the center of the screen. No adjustments are made
for multi-monitor applications.
 
 
I presume the normal way people use dual monitors is to have the desktop
continue onto the second monitor?
 
Question - With a dual monitor , which one puts the form in the middle
of the first monitor?  I haven't tried it as my external  monitor is
currently in another city and so its not much use.  That help is vague
enough I wouldn't be sure until I tried it.   But for future
compatibility it would be nice to know...

Nearly, but by the time I could afford one, I got a ZX Spectrum +3

Sort of thing you had to prop upright/wedge in with a piece of lego or

Re: [DUG] Need help in locating exe in task manager

If I understand correctly, you're wanting some code to search for an

EnumWindows is the API function you're probably looking for.

Ditto.

Delphi 2007 is definitely better than any of it's predecessors, and
although we've got 2009, we haven't found the time to make the move yet.

We're still holding out for Win64 support though.  We'd move a lot

Re: [DUG] Getting command lines of all open programs

[Conor Boyd]

John,

Rather than enumerating windows, for this I think you'll want to
enumerate processes instead.

With a quick google for enumerate windows processes I found some leads
you could pursue (including this one:
http://www.codeproject.com/KB/threads/enumprocnt5.aspx)

It's definitely relatively easy to get a list of running process ids
(PIDs), and after that I presume there will be some function you can
call to tell you all you need to know about a specific process.

I presume what you want to do is possible since, for example,
Sysinternals' Process Explorer displays the commandline for each
process.

Cheers,

Conor

Is there a way to make a list of command lines of all open program
windows?

I have a utility that already captures the title bar of all open program
windows - I use it when I suspend my laptop in case Windows won't resume
(which it often doesn't) so I can know what windows were open.

The next neat addition would be to have the command lines, so I can then
have an option to reopen the programs that were open last timenow
that would be neat eh?

I remember seeing once a Delphi demo example of a task-manager like
program which probably had stuff like this, but haven't been able to
find it...

FYI here is the essentials of how I find the open program windows, in
case someone can see how to extend it a littlethe ideal would be to
make a second string list of the matching command lines.  (It gets the
titles of all open windows and writes them into a memo and a disk file).

//http://www.experts-exchange.com/Programming/Languages/Pascal/Delphi/Q_
21550337.html
procedure TfrmATMore.ATMakeWindowList;
var
 TopWindow   : HWND;
 WinName : array[0..Max_Path] of Char;
 x   : Integer;

  function GetAllWindows(Handle: HWND; NotUsed: Pointer): Boolean;
stdcall;
  var
   temp,
   pt : hwnd;
  begin
Result := True;

//Get parent of the window
Temp:=Handle;
repeat
 pt:=Temp;
 Temp:=GetParent( Temp );
until (Temp=0);

if IsWindowVisible(pt) then begin
  //Just add without duplicates
  if frmATMore.WindowList1.IndexOf(Pointer(pt))=-1 then
frmATMore.WindowList1.Add(Pointer(pt));
end;
  end;

begin
  TopWindow   := Handle;
  WindowList1 := TList.Create;
  Memo1.Lines.Clear;
  memo1.Lines.Add(xfAdate+spc+xfaTime+' Windows open are:');

  try
If NOT EnumWindows(@GetAllWindows,Longint(@TopWindow)) then
RaiseLastOsError;

for x := 0 to WindowList1.Count - 1 do
begin

  GetWindowText(HWND(WindowList1[x]),
WinName,
SizeOf(WinName) - 1);

  if WinName'' then memo1.Lines.add(WinName);
end;
  finally
WindowList1.Free;
  end;
  memo1.Lines.add('__');

  memo1.lines.SaveToFile(ATSaveWindowsNamesFile);

Re: [DUG] Animated progress Throbber

[Conor Boyd]

In the past I've done something along these lines (and have described it
as a throbber too!) by placing a button with a lightbulb icon (or
similar) on the form (or in my case, on a panel on a status bar) and
having a timer make it visible and invisible every half second.

The reason I used a button was so the user could click on it for more
detailed progress info.

Not a particularly nicely self-contained approach, but I never got round
to turning into a component or similar.

You could have a look at the JVCL libraries; maybe they've got
something?  We've used things like their toast windows to nice effect.

Is there any Delphi equivalent of a throbber?   This is used when
showing 
progress when the total length if a task in progress is not known so its
useful to show something is happening. and is usually a small animated
icon.

Would be nice to have such a component to place on a foirm.

Used a lot outside of Delphi - Examples are

-IE7 when page loading - the animated rotating circle whown on a tab
header while a page is loading, and gets replaced with the sites icon
when done.
-Firefox similar
-Vista gives a progress bar with the highlight swishing along it but not
changing length of the progress bar, also the animated circle mouse
cursor.
-Older versions of IE used to have an animated flag that waved while a
page was loading - remember?

(This visual component is called a throbber in browser circles).

If I know the length then I can use a ProgressBar, but one does not
always...and the Vista progress bar only shows on Vista of course.

[DUG] Delphi .NET Obfuscation

[Conor Boyd]

Hi all,

Just wondering if anybody has any opinions or suggestions on obfuscating
Delphi (RAD Studio) 2007 .NET assemblies?

Part of my team have been working on such an assembly and are thinking
they need to obfuscate it.

I know there are differing opinions on the merits of bothering to
obfuscate assemblies, but I don't have direct experience myself, and I
wondered if anybody wanted to comment specifically on obfuscation from a
Delphi POV.

Cheers (and have a happy Christmas break).

Re: [DUG] HTTP Upload Progress

[Conor Boyd]

Here's my reply to your original request earlier in the week.
 
I've used the Indy library that comes with Delphi to do HTTP uploads
with progress notification.  Works quite well.
 
E.g.
 
  FHTTPClient := TIdHTTP.Create(nil);
  with FHTTPClient do begin
ProxyParams.ProxyServer:= ProxyHost;
ProxyParams.ProxyPort := ProxyPort;
ProxyParams.ProxyUsername := ProxyUsername;
ProxyParams.ProxyPassword := ProxyPassword;
OnWork := HTTPWorkEvent;
OnWorkBegin := HTTPBeginWorkEvent;
OnWorkEnd := HTTPEndWorkEvent;
  end;
 
I use it to upload a JPEG to a webserver running Gallery
(http://gallery.menalto.com/) as follows:
 
function TGalleryHelper.AddImage(const AlbumID: Integer; const Image:
TStream; const ImageFilename, Caption, Description, Summary: String):
TGalleryStatus;
var
  Command: String;
  Response: String;
  ImageStream: TIdMultipartFormDataStream;
begin
...
ImageStream := TIdMultiPartFormDataStream.Create;
try
  ImageStream.AddFormField('g2_form[cmd]', 'add-item');
  ImageStream.AddFormField('g2_form[protocol_version]', Format('%f',
[PROTOCOL_VERSION]));
  ImageStream.AddFormField('g2_form[set_albumId]', Format('%d',
[AlbumID]));
  ImageStream.AddFormField('g2_form[caption]', Caption);
  ImageStream.AddFormField('g2_form[force_filename]',
ImageFilename);
  ImageStream.AddFormField('g2_form[extrafield.Summary]', Summary);
  ImageStream.AddFormField('g2_form[extrafield.Description]',
Description);
  ImageStream.AddObject('g2_userfile', 'image/jpeg', Image,
ImageFilename);
 
  Response := FHTTPClient.Post(Command, ImageStream);
finally
  ImageStream.Free;
end;
...
 
The events that the TIdHTTPClient class raises can be handled as
follows:
 
procedure TGalleryHelper.HTTPBeginWorkEvent(Sender: TObject; AWorkMode:
TWorkMode; const AWorkCountMax: Integer);
begin
// Do something with AWorkCountMax, e.g. set the max value on a
progress bar.
end;
 
procedure TGalleryHelper.HTTPEndWorkEvent(Sender: TObject; AWorkMode:
TWorkMode);
begin
// You're all done.
end;
 
procedure TGalleryHelper.HTTPWorkEvent(Sender: TObject; AWorkMode:
TWorkMode; const AWorkCount: Integer);
begin
// Do something with AWorkCount, e.g. set the progress value of a
progress bar.
end;
 
I have all this running in a thread to keep my GUI nice and responsive
while the upload is happening.
 
HTH, if you've more questions, let me know.

The way I implemented this (in a Java web server) was that once the form

repeatedly asked the server how the file upload was progressing, and
updated the amount of colour in a progress bar. The upload was attached
to the session, so  the ajax call was able to grab the info structure
from the session and query it (as the file upload specifies how big
something is and as the upload is happening, you can just specify in the
structure how much you had received).

Hi All.
I am wondering if anyone has seen or has any Delphi code that
will do an http file upload, BUT that shows you the upload progress.
I have looked at the Synapse code for doing this, but it doesn't
have the ability to show the progress.
Why use HTTP File upload and not FTP? simple answer, not every
site has FTP enabled...as we have found out, and email has been a bit
unreliable.
I have taken a look at the odd Java plugin that does this which
would be good because I could just have my app. look at a webpage
instead of build it into the exe, but then, no guarantees that java is
enabled eithersigh...the joys :-(
OR someone might even have a brighter idea ;-)

Re: [DUG] HTTP Upload Progress

[Conor Boyd]

Why everybody's obsession with forms/webpages?

HTTP as a protocol has nothing specific to do with forms/pages/javascript.

There's no reason why native code can't talk HTTP.  Indeed, a lot of the Indy 
components are for just that purpose, and I even provided an example of HTTP 
upload progress in native code.

This is the Delphi list, after all. :-Þ

Just curious...

 and repeatedly asked the server how the file upload was progressing, 
 and updated the amount of colour in a progress bar. The upload was 
 attached to the session, so  the ajax call was able to grab the info 
 structure from the session and query it (as the file upload specifies 
 how big something is and as the upload is happening, you can just 
 specify in the structure how much you had received).

 Hi Al, sorry this is a repeated post, as I have not received any
 emails from the list in a week, then I got an email to reconfirm
 my email address because the emails were meant to be
 bouncingwhich is strange because its my main email address and
 I have been getting emails okanyway using gmail now.
 So, here is my post again. Appologies if its already been answered.
  
 Hi All.
 I am wondering if anyone has seen or has any Delphi code that will
 do an http file upload, BUT that shows you the upload progress.
 I have looked at the Synapse code for doing this, but it doesn't
 have the ability to show the progress.
 Why use HTTP File upload and not FTP? simple answer, not every
 site has FTP enabled...as we have found out, and email has been a
 bit unreliable.
 I have taken a look at the odd Java plugin that does this which
 would be good because I could just have my app. look at a webpage
 instead of build it into the exe, but then, no guarantees that
 java is enabled eithersigh...the joys :-(
 OR someone might even have a brighter idea ;-)
  
 Jeremy

Sometimes there is something to be said for monolithic .exe's ;-)

 Hi

 I had Sharemem in my app.  I needed to Change this to SimpleShareMem.

 Unfortunately we have a large number of Dlls in the wild so until they

 can all be changed this might be a temporary measure.

 Hi


 Just made a brand new application and it works fine.  Any ideas what 
 might be wrong with my main app (ReportMemoryLeaksOnShutdown is not 
 getting set false anywhere).

 Hi

 I just tried the ReportMemoryLeaksOnShutdown := true; thing and it 
 didn't report any errors for me (I put a button on that created a 
 TStringList without freeing it it).  Any ideas what I am doing
wrong?

 Apparently FastMM is the default for Delphi 2007.  Where do I 
 configure debug / release modes?

 Thanks
 Rob

 compile in FastMM Memory manager into your program.. Debug mode 
 catches everything.. release mode speeds it up.
