There is a peculiar truncation at around 80 characters in your second
example. The output might be getting broken down into multiple lines.

You might want to inspect the raw content of the sData variable before
dumping it into a text file.

Also, try changing this line:
> slTemp.Add(sData);

To this line:
> slTemp.Text := sData;

Re: [Lazarus] Is there a global timezone-independent time available?

[Denis Kozlov via lazarus]

You can use LazSysUtils.NowUTC, and then there is also PascalTZ package 
if you want to convert between timezones.


There is a ticket with a patch for adding a similar function to FPC, but 
it needs some attention:
https://bugs.freepascal.org/view.php?id=30394

If I use Now() to retrieve a TDateTime value I get it in whatever timezone

And there is no indication of the timezone used (TDateTime is just a double

So now I wonder if there is some kind of globally constant time one can read
which can be used in scheduling applications no matter what time zone is used.
For example something like NowUTC() or similar?

I have been struggling with the user part of a remote monitoring system, which
will run on a RaspberryPi under Linux (Debian flavour).

And there are lots of problems when going between the actual remote system and
the config application because of the time zone differences.
It would help a lot if one could use a time that is not messed with and is the
same everywhere...

The important thing here is that two systems located at different places on
Earth should agree on such a time value if it is taken at the same absolute
instant.

And what is the useful resolution of the times?
seconds, miliseconds or what?

Re: [Lazarus] How to hide pop-up menu before taking a screen snapshot?

[Denis Kozlov via lazarus]

Hi,

I had a similar experience with taking a screenshot programmatically. 
Simply waiting or processing application messages after hiding the form 
often doesn't help, and results in a form being a part of the screenshot 
anyway.


I managed to work around it by forcing Windows to repaint everything on 
the desktop by broadcasting WM_PAINT message, like so:


SendMessageTimeout(HWND_BROADCAST, WM_PAINT, 0, 0, SMTO_ABORTIFHUNG, 
1000, MsgResult);


You might also need to disable transition effects (fade-in and fade-out) 
by setting the DWMWA_TRANSITIONS_FORCEDISABLED flag on the form before 
hiding it, and then unsetting it when showing the form again.


DwmSetWindowAttribute(AForm.Handle, DWMWA_TRANSITIONS_FORCEDISABLED, 
@dwAttribute, SizeOf(dwAttribute));


Good luck,
Denis

I have worked on a tool to copy a region of the Windows desktop for use in
illustrations. The tool consists of a transparent form which is supposed to be
located on top of the area to copy.

This form has a pop-up menu where there are 3 items to select from:
- Copy image
- Copy position
- Close

When I use the "Copy image" function the resulting image contains the selected
menu item caption on top of the copied desktop bitmap...

I have tried various ways to get rid of this but everything I tried has failed.
So how can I hide the menu item caption in code before I make the image
extraction?

I even added a timer set to 50 ms interval and put the image copy in its ontimer
event hoping that the menu click should have exited and the text disappeared
before the image copy happened, but no go...

Here is the way the copy is commanded via the popup menu:
http://blog.boberglund.com/files/Lazarus_popmenu_usage.png

And here is a captured image where the popup caption is visible:
http://blog.boberglund.com/files/Lazarus_popmenu.png

As you can see the caption of the clicked menu item is still present in the
screenshot image...

Here is parts of the code:

procedure TfrmMain.miCopyImageClick(Sender : TObject);
begin
   //CopyScreenRect;  //Moved to timer
   //miCopyImage.Visible := false; //Does not work
   //self.Refresh;  //Does not work
   timCopyImg.Enabled := true;  //make copy inside timer event?
end;

procedure TfrmMain.miCopyPosClick(Sender : TObject);
begin
   SaveRectCoords; //Saving rect coordinates to clipboard (OK)
end;

procedure TfrmMain.timCopyImgTimer(Sender : TObject);
begin
   timCopyImg.Enabled := false;
   miCopyImage.Visible := false; //Does not work, caption still present
   self.Refresh;  //Does also not work to remove caption
   CopyScreenRect;
   miCopyImage.Visible := true;  //Put it back to enable next capture
end;

procedure TfrmMain.CopyScreenRect;
var
   MyCapture : TBgraBitmap;
   Clip: TRect;
begin
   try
 Clip := Bounds(Self.Left, Self.Top, Self.Width, Self.Height);
 Self.Visible := false; //Hide selection form before copy
 //Self.Hide;  //Not working for popup menu item...
 MyCapture := TBgraBitmap.Create();
 MyCapture.TakeScreenShot(Clip);
 Self.Visible := true; //Show selection form after copy is done
 //Self.Show;  //Not working for popup menu item...
 Clipboard.Assign(MyCapture.Bitmap);
   except
 on E: exception do
   Clipboard.AsText := E.Message;
   end;
end;

Even Self.Visible or Self.Hide do not remove the menuitem caption

What can I do?

Re: [Lazarus] Feedback requested: File Search, a visual file search utility

[Denis Kozlov via lazarus]

Hi Anthony,

It looks great!

If you were looking for new features, please consider the following 
features:


1. Show the snippets from the file where the content was found, with
   some context lines around the matches.
2. Allow specifying regular expressions for content search (optionally).

These are killer features that any file content search app must have in 
my opinion.


You can see an example implementation in AstroGrep (Windows only):

The File Search utility is a stand alone tool for Mac, Windows, and

containing text, file size, and file dates. The full source code is 
available on github and it has no dependencies other than the LCL, so

Re: [Lazarus] With new Win32 manifest LongPathAware I cannot make long filename

[Denis Kozlov via lazarus]

The new "Long path awareness" option is working!

Apparently, you need to do both, embed the manifest and enable long 
paths in the registry or group policy. Only then you will be able to use 
long paths without the "\\?\" prefix.


To enable via the Local Group Policy Editor, navigate to Local Computer 
Policy > Computer Configuration > Administrative Templates > System >

I would also suggest IPC through TCP/IP.

I have deployed several tools with such IPC implementation which operate

networking library that works in both FPC and Delphi, such as Synapse 
 (make sure to use the 
latest trunk version). Both Java and C# have extensive TCP/IP components 
so you will have no problem there.

Re: [Lazarus] Replacing accented letters

You could use Unicode character decomposition.

For example, é (U+00E9) can be decomposed into an equivalent string of 
the base letter e (U+0065) and combining acute accent (U+0301).


Then, you could simply delete combining acute accents, leaving just the 
base letters.

Re: [Lazarus] Use rare Win32 API in LCLIntf.SetForegroundWindow

[Denis Kozlov via Lazarus]

I would advise strongly against the use of SwitchToThisWindow API 
function in Lazarus. Mainly because it states in the docs: /This 
function is not intended for general use. It may be altered or 
unavailable in subsequent versions of Windows./


Read more in Raymond Chen's blog - The life story of the 
SwitchToThisWindow function:

Re: [Lazarus] A simple way to stop the never ending story of long executable?

[Denis Kozlov via Lazarus]

I also agree with "Use external gdb debug symbols file" being ON by 
default for a new Lazarus project.


Unless of course some debug info formats didn't support it, which would 
raise other questions.


This is only a default option for new projects, which would affect 
mostly new users or quick test projects, where it should always be 
beneficial to keep executable file small.

perfectly, at least under Linux.


Wouldn't it be nice to set it active by default?

This could make unnecessary in many cases a different build mode for 
testing and for deploying, and would stop the complaints about "long 
executable".

Re: [Lazarus] TEdit appears empty when text is too long

Thanks. This seems to confirm my theory.

See unit lclversion.


Thanks! Somehow I just couldn't find it.

Is it theoretically possible to implement a compile time define for 
Lazarus version?


Perhaps an extra define that Lazarus passes to compiler automatically?

Thanks,
Denis

Re: [Lazarus] IDE Docking windows and Editor Toolbar

[Denis Kozlov]

Is it a known issue, or by design, that the Editor Toolbar doesn't
appear when the Anchor Docking packages is installed? Is it some docking
window limitation?


It is somewhat documented in: http://bugs.freepascal.org/view.php?id=29863

All toolbars disappear once you install anchor docking package, so 
toolbars need to be re-enabled manually. That's one of the problems. The 
other one is more severe, i.e. "TWinControl.WMSize loop detected".

Which version of Lazarus and FPC are you using?


Just ran a quick test with:
Lazarus 1.4.4 + FPC 2.6.4
Lazarus 1.6.1 + FPC 3.0.0

No issues, even if the key is down for 2 minutes.

Provide more details and a complete example project, otherwise it seems 
that you may have a problem elsewhere in your code.

That's ok, but i would like to know if there are better ways to do that?


You can try TFPStringHashTable and TDictionary/THashMap generics. Maybe 
they will perform faster than TStringList.

[Lazarus] A new PascalTZ - time zone database for FPC / Lazarus

[Denis Kozlov]

Hello,

I have forked PascalTZ  library about a
year ago with a goal to fix many parsing and time zone conversion problems,
refactor existing code and implement a testing framework.

This work has just finished with a milestone release of PascalTZ 2.0
. Master branch also
contains a design/runtime package for Lazarus IDE.

PascalTZ 2.0 is backward compatible with code written for PascalTZ 1.0, but
the usage has been somewhat simplified with addition of new methods:

> // Load time zone database from "tzdata" directory
> PascalTZ.DatabasePath := 'tzdata';
> // Convert current time in Paris to Chicago time
> PascalTZ.Convert(Now, 'Europe/Paris', 'America/Chicago');

Should the old PascalTZ in Lazarus CCR
 be removed
and the PascalTZ article  on the wiki
reflect the new home?

Regards,
Denis

Re: [Lazarus] Target Survey

[Denis Kozlov]

80% Windows (mostly Win32 apps, few console tools)
15% Linux (console services and tools)
3% Mac (console tools)
2% FreeBSD (console services and tools)

Plan is to increase the share in Linux and Mac by porting some GUI apps.
