Yes. There are some windowed controls such as TListBox and TListView that have a data or object property for each row that you can use to store some sort of ID code.

RE: [DUG]: Const
From the help file:
Typed constants, unlike true constants, can hold values of array, record,
procedural, and pointer types.
In the default {$J+} compiler state, typed constants can have new values
assigned to them; they behave essentially like initialized variables. But if
the {$J} compiler directive is in effect, typed constants cannot change
value at runtime; they are, in effect, read-only variables.

RE: [DUG]: PDF Components
I would assume they are still developing it, those are features I would like to see as well as the ability to align text. Of course with the full source available there is nothing to stop anyone from developing those features themselves... However you would not require smart SQL scripts, you just require the ability to write code that can step through the data in the order in which the bands are processed in a QR report. Not so hard at all. I just wrote code to create a CSV file (for Excel) in the same format as a report and that was not at all difficult.

RE: [DUG]: PDF Components
The latest version 0.9 (available on the Delphi Super Page) adds a few more basic functionalities (like text alignment) but you would basically have to simulate the grouping in code. When I did my grouped reports in QR, I used one query for both the group header and the detail, which made it relatively simple to produce a grouped CSV output file when I wanted to use that format. It wouldn't be hard to create PDF using that format with these components. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Mark Howard Sent: Thursday, 25 October 2001 13:40 To: Multiple recipients of list delphi Subject: Re: [DUG]: PDF Components Jeremy Have had a quick look only (being a sole trader, usually can't follow a thread to its conclusion in one go!)

RE: [DUG]: equiv in Delphi
It's an OLE object reference Delphi equiv = GetOleObject MSDN Home MSDN Library Visual Basic Reference Visual Basic for Applications Reference GetObject Function See AlsoExampleSpecifics Returns a reference to an object provided by an ActiveX component. Syntax GetObject([pathname] [, class]) The GetObject function syntax has these named arguments: Part Description pathname Optional; Variant (String). The full path and name of the file containing the object to retrieve. If pathname is omitted, class is required. class Optional; Variant (String). A string representing the class of the object. The class argument uses the syntax appname.objecttype and has these parts: Part Description appname Required; Variant (String). The name of the application providing the object. objecttype Required; Variant (String). The type or class of object to create. Remarks Use the GetObject function to access an ActiveX object from a file and assign the object to an object variable. Use the Set statement to assign the object returned by GetObject to the object variable. For example: Dim CADObject As Object Set CADObject = GetObject(C:\CAD\SCHEMA.CAD) When this code is executed, the application associated with the specified pathname is started and the object in the specified file is activated. If pathname is a zero-length string (), GetObject returns a new object instance of the specified type. If the pathname argument is omitted, GetObject returns a currently active object of the specified type. If no object of the specified type exists, an error occurs. Some applications allow you to activate part of a file. Add an exclamation point (!) to the end of the file name and follow it with a string that identifies the part of the file you want to activate. For information on how to create this string, see the documentation for the application that created the object. For example, in a drawing application you might have multiple layers to a drawing stored in a file. You could use the following code to activate a layer within a drawing called SCHEMA.CAD: Set LayerObject = GetObject(C:\CAD\SCHEMA.CAD!Layer3) If you don't specify the object's class, Automation determines the application to start and the object to activate, based on the file name you provide. Some files, however, may support more than one class of object. For example, a drawing might support three different types of objects: an Application object, a Drawing object, and a Toolbar object, all of which are part of the same file. To specify which object in a file you want to activate, use the optional class argument. For example: Dim MyObject As Object Set MyObject = GetObject(C:\DRAWINGS\SAMPLE.DRW, FIGMENT.DRAWING) In the example, FIGMENT is the name of a drawing application and DRAWING is one of the object types it supports. Once an object is activated, you reference it in code using the object variable you defined. In the preceding example, you access properties and methods of the new object using the object variable MyObject. For example: MyObject.Line 9, 90 MyObject.InsertText 9, 100, Hello, world. MyObject.SaveAs C:\DRAWINGS\SAMPLE.DRW Note Use the GetObject function when there is a current instance of the object or if you want to create the object with a file already loaded. If there is no current instance, and you don't want the object started with a file loaded, use the CreateObject function. If an object has registered itself as a single-instance object, only one instance of the object is created, no matter how many times CreateObject is executed. With a single-instance object, GetObject always returns the same instance when called with the zero-length string () syntax, and it causes an error if the pathname argument is omitted. You can't use GetObject to obtain a reference to a class created with Visual Basic. Contact Us | E-mail this Page | MSDN Flash Newsletter © 2001 Microsoft Corporation. All rights reserved.

From Peter Below : - If you want to have a separate taskbar button for each secondary window you have two options: 1. override the CreateParams method of each secondary form and add the WS_EX_APPWINDOW style: procedure TForm2.CreateParams(Var params: TCreateParams); begin inherited CreateParams( params ); params.ExStyle := params.ExStyle or WS_EX_APPWINDOW; end; If you click on a secondary forms taskbar button while another app is active this will still bring all the applications forms to front. If you do not want that there is option 2. reparent the secondary forms to the desktop procedure TForm2.CreateParams(Var params: TCreateParams); begin inherited CreateParams( params ); params.ExStyle := params.ExStyle or WS_EX_APPWINDOW; params.WndParent := GetDesktopwindow; end; Note that this can cause some problems with modal forms shown from secondary forms. If the user switches away from the app while a modal form is up and then back to the form that showed it the modal form may hide beneath the form. It is possible to deal with this by making sure the modal form is parented to the form that showed it (using params.WndParent as above) but this is not possible with the standard dialogs from the Dialogs unit and exceptions, which need more effort to get them to work right (basically handling Application.OnActivate, looking for modal forms parented to Application via GetLastActivepopup and bringing them to the top of the Z-order via SetWindowPos).

[DUG]: Contracting issues - Comments please
Iam having some difficulty in finding a contracting company in Christchurch totake over maintenance ofexisting work. These consist of four databases with Delphi applications for data entry, reporting etc. One of the databases is being turned into a web based application by another company. These are desktop databases, not client/server. They run on small office networks with less than 10 workstations, and in few cases will there ever need to be simultaneous access to the data by more than one person. When I first started in this business, there were four or five companies that I knew of personally that were doing this sort of thing. No longer. Every company that I knew that was doing job work is either full up and not taking new clients, or they have some flagship product that they are busy marketing and selling flat out and don't have the time for other work, or they have closed up their business and now work for someone else. This is not necessarily the situation in Auckland and Wellington but it appears to be the situation in Christchurch for Delphi work. The choice to use Delphi over the other product systems available was not taken lightly. Once a commitment of this nature has been made it is costly and time consuming to reverse. Given that most of the work is for inhouse applications, three possible lines of action suggest themselves: 1. Obtain the services of a contracting firm in another part of the country. You can only go sofar with remote working, unless you have full administrative access to the machines the softwareis running on.Someone would still have to physically install and set up the software in the environment in which it is being used.One of the problems we have encountered is that PC support staffout there don't know anything about setting the BDE upon a network system. 2. Develop in house This option entails significant financial expense for the organisations involved in purchasing and maintaining the software tools and theystill have to bring in someone fromoutside to do the actual work. That person is unlikely to have the experience and knowledge of an independent contractor. 3. Port software to a different development environment. In the circumstances thebasic database would probably be MS Access and the Access report builder would be adequate for most reporting requirements.VB or VC would besuitable fordata entry applications which typically require rather more sophistication thanAccess is capable of offering. This approach also provides an upgrade path for existing MS Access databases which exist in the client environments. Some of these would be better run on VB/VC. In regard to the above, I rather suspect that more of this low level in house stuff is already being done in MSAccess than any other database (how many people do you know that use Corel Paradox for their organisation's internal databases, huh?) and with it being the native database format for VB/VC it makes more sense to go down this path than to stick with Delphi, if we can't get anyone to handle the Delphi work.

Slighty off topic here. I'm writing a help file for my delphi app and I

ExecProgram which works like delphi's WinExec and requires an executable

equivalent to ShellExecute. The FileOpen macro doesn't seem to work.
Is there a standard way of doing this?
I have discovered a way which appears to work OK
ExecProgram('Explorer.exe http://www.StationPlaylist.com', SW_SHOWNORMAL)
Can anyone see any problems using Explorer.exe this way? Will it work

Title: Message
Has
anyone looked at the source code for correcting this issue, if they have the
professional version?
We
currently use 2.0 registered version for some some software. I did a search for
GetTempPath in all of the source code and found only one file,
QRPRNTR.PAS
There
is a function in there defined as follows. This is the only reference to the API
call in this unit.
function TempFilename : string;var AName, ADir :

Is
there any Borland documentation for the Quickreport thing?
Qusoft on their website says "We are not responsible
for the free version supplied with Delphi, Borland is" then on Borland's web
site, I can't find any documentation at all of the
problem.
Also
I am not very thrilled with Qusoft's explanation of the problem as saying
glibly that MS's long temp paths break lots of apps when all they had to do
was follow the API documentation. For the GetTempPath function it gives the
following:
"If
the function succeeds, the return value is the length, in characters, of the
string copied to lpBuffer, not including the terminating null character. If
the return value is greater than nBufferLength, the return value is the size
of the buffer required to hold the path. "
Buffer overruns are one of the most common errors
known to mankind :)

[DUG]: DsgnInft unit D5 Standard
I'm updating a
project from Delphi 3 to Delphi 5.
One of the components
causes this error message at compile time:
"cannot find unit

I checked and found
only a dsgnintf.int file, not a dcu or pas. But Delphi 3 puts a Dsgnintf.dcu
unit into its Lib directory.
The reference to
DsgnIntf is made in the Register procedure, which for this component looks like
this:
procedure
Register;
implementation
usesDsgnIntf;
type{Design-time testing by Double-clicking or
from popup menu take Test}{Added by Ahto

constCUSTOM_BUTTON_ID=255;MAX_PATH_DISPLAY_LENGTH=35;
////procedure
Register;beginRegisterComponentEditor(TBrowseFolder,
TDialogTest); RegisterComponents('Dialogs',

Is Borland in the
habit of shipping DsgnIntf.dcu depending on the edition of Delphi? Using D5

So I decided
it must be something new in the of the package units. I just

everything was then fine. Weird!!
So what bugs me it that when this sort of error occurs my Delphi

me there is an error at compile time but doesn't tell me which

Its very annoying when you have lots for forms and you don't know

Is there a setting somewhere I haven't got set to tell me which unit/form

RE: [DUG]: URL Link Checker
It would depend on where the dialog originated from. In some cases where the server requires the client to provide authentication, it sends back a header like this: WWW-Authenticate: Basic realm=My Realm HTTP/1.0 401 Unauthorized Typically this is used to authenticate access to a restricted part of a web site on an HTTP server. Most web browsers recognise this by popping up a dialog box asking for your username and password. The browser then re-requests the same page passing back the information from the dialog. I don't know how proxy servers request authentication, whether they do it by sending HTTP headers or what. If you are using an HTTP component to connect then I would have assumed you could see the headers it sends back. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of C Fraser Sent: Monday, 10 September 2001 10:19 To: Multiple recipients of list delphi Subject: [DUG]: URL Link Checker Hi all, I am trying to create a basic URL link checker...

RE: [DUG]: System Tray app
The one I have used which I am happy with is mdTrayIcon by Martin Djaernes. You can make an application autohide to the system tray (like the Volume Control popup adjustment) with the following code by firing the Application.On Deactivate event, telling it to hide the main form. I suppose setting the form to minimise first would produce the animated effect that ZoneAlarm and other tray apps sometimes produce. If you have a close button on the title bar and want to minimise to the system tray when they click the close button (like ZoneAlarm does), use this as an example: 1. Add a property to the form called PermitClose. 2. Set this to false in FormCreate 3. In the FormCloseQuery event handler, put this code: MainForm.Hide; CanClose := PermitClose; 4. In the private declarations of your form, put this procedure declaration procedure EndSession(var Message : TMessage); message WM_QUERYENDSESSION; 5. Here is the code of this procedure: procedure TMainForm.EndSession(var Message : TMessage) ; begin PermitClose := true; Message.Result := Integer(True); end; How does this work? The CloseQuery event procedure is called every time the user tries to close the form. The default behaviour is to tell Delphi that the application can't be closed, so the form appears to disappear to the system tray. The EndSession procedure is a message handler for the WM_QUERYENDSESSION operating system message. Windows sends this message to each running application whenever the user attempts to shut down, log off or restart their computer. The message essentially asks the application whether it can exit or not. It does not shut down the application at this point. If the application returns false then Windows will not be shut down. Returning true indicates the application can be exited. The actual attempt to close the application will occur when the message WM_ENDSESSION is sent by Windows, which occurs if all applications return true. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Ross Levis Sent: Wednesday, 5 September 2001 16:45 To: Multiple recipients of list delphi Subject: RE: [DUG]: System Tray app Well I downloaded installed RXLIB and setup a basic tray app. The EXE is 299k - 12k larger than an empty form.

RE: [DUG]: Shared BDE Setup
I also have a file bdenet.zip that I downloaded from the Borland site, which I assume is under the BDE part. USEFULLNESS --- This example can be used to setup BDE client machines to point to a central set of BDE DLL and configuration files. It allows easy updates to the BDE by having only one copy, therefore only needing to update one set of BDE DLLs. The registry functions can be easily called from within an installation program or in startup code of a program. These methods will allow seamless installation of a BDE application with out the need for a separate BDE install. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Mark Derricutt Sent: Monday, 3 September 2001 09:46 To: Multiple recipients of list delphi Subject: [DUG]: Shared BDE Setup I have a client that wants to setup a shared BDE for all their users, cause they don't want to install the software on every machine and have one standard configuration/setup.

RE: [DUG]: Wrap text
You can wrap text yourself in a TStringGrid. I did this once in a project.

As I recall, the specifics of the problem are how the drivers handle the video card's memory becoming full. The most commonproblem that is seenis with icons (for example the VCL component icons). Over a certain number of icons they eitherstart to draw funny, or your PC just locks up. You may find that you install a new componentpackage and then the next time you run Delphi, your PC locksup. To be able to run Delphi at all on my PC (S3 Virge) beyond a certain number of installed components, HW acceleration has to be set to None.

RE: Listbox items (Was: Re: [DUG]: array of TStringList)
In my app I handled this (in a TListView) by writing an event handler for the OnDeletion event. This allowed me to call the Clear method freely without worrying about memory. Referring to my previous code, this is the event handler: procedure TMainForm.ServicesListDeletion(Sender: TObject; Item: TListItem); var PLong:PLongInt; //This event handler frees the dynamic variables allocated when the list items were //created. These variables are pointed to by each list item's Data property. begin PLong:=PLongInt(Item.Data); if PLong nil then Dispose(PLong); end; Unfortunately there does not appear to be a similar way of handling the deletion of items in a list or combo box. In a TList as I noted you can simply override the destructor. Here is the class I used in a reporting system: TCounterList = class(TList) [...] destructor Destroy; override; procedure Empty; end; and its implementation destructor TCounterList.Destroy; begin Empty; inherited Destroy; end; procedure TCounterList.Empty; begin while (Count 0) do begin Items[Count-1].Free; Delete(Count-1); end; end; -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Paul Lowman Sent: Wednesday, 11 July 2001 09:29 To: Multiple recipients of list delphi Subject: Re: Listbox items (Was: Re: [DUG]: array of TStringList) Ross Delphi definitely does not free objects when the list is free'ed.

It is not possible to create numerous objects with the same name. When you create an instance of a class (an object) you are doing several things: 1. Delphi reserves some memory for you 2. Delphi gives you in the variable on the left hand side, a reference to that piece of memory. If you then create another instance of the object using the same variable name, you have lost access to the bit that you had before. it is still there but you have no way of accessing it, because the variable now points to the new bit you got. You can do this ten times but at the end you will still only be able to access the last bit. To get around this little problem when you need to keep lists of objects created dynamically, Delphi provides the TList class. You can use a TList or make a derivative from it. It would be usual to override the destructor to ensure all the memory is freed in your objects. Now, when using a TList the above steps become: 1. Delphi reserves some memory for you 2. Delphi gives you in the variable on the left hand side, a reference to that piece of memory. 3. You add the value of that variable to a TList object. Then you can use the methods of TList to access all those dynamic objects you have created. In the days before OO we used to use linked lists of pointers to do the same thing. Compared to that a TList is a doddle. Addressing to your particular situation. A record is not an object. A Tobject is an object. I used to use records until I discovered how to use TList to link a whole lot of dynamically created objects. To give an example I have just updated an application that uses counters to count numbers in a big report, and do various calculations etc. It used to use various TStringLists to store all the counters. I updated it to use OO stuff. This is good because there are two different types of counter and one is a subclass of the other. All you have to do is: * Create an instance of your object e.g. MyObject := TMyObject.Create * Do something with it...set the fields or something * Add it to the Objects property of the list box items (which is probably implemented as a TList) . No typecast needed since everything is descended from TObject. Now you can safely reuse MyObject to create another instance, as the reference is now saved in the list box. (Don't free it though, as it still points to an instance, but if you wish you can set it to nil without affecting any instances of your object) When you have to do something with your object, it looks like this: MyObject := TMyObject(ListBox1.Items.Objects[X] You have to typecast it because Delphi stores it as a TObject and won't let you access any of the methods or properties other than for a TObject, if you don't do the typecast, also you will get an invalid type error from the compiler. Note that the Objects property still contains the reference until that list item is deleted.The question I am not at all sure about is whether Delphi frees the memory associated with each object reference when the list item is removed from the list. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Ross Levis Sent: Friday, 6 July 2001 23:33 To: Multiple recipients of list delphi Subject: Re: Listbox items (Was: Re: [DUG]: array of TStringList) Thanks James, Ben Reg.

Subject: [DUG]: TWebBrowser and Enter key
When using TWebBrowser and filling some web page form, pressing Enter
key
does not submit data entry.
Say I go to www.anzwers.com.au and using IE type 'Delphi' and
then press
enter. It'll go to search for Delphi.
If I do exactly the same thing using the simplest possible Delphi
application with TWebBrowser in it, pressing enter key does
nothing, I have
to click the search (or submit) button with the mouse.
All I have in my application is a basic form with TWebBrowser in
it and this
code under Go button (not default).
Flags := 0;
WebBrowser1.Navigate(WideString('www.whatever.com'), Flags, Flags,
Flags,
Flags);
Is there something I am missing ?

RE: Listbox items (Was: Re: [DUG]: array of TStringList)
-Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Ross Levis Sent: Friday, 6 July 2001 12:22 To: Multiple recipients of list delphi Subject: Listbox items (Was: Re: [DUG]: array of TStringList) Thanks all for the help. I think I will use a static array and limit the numbers. I have another newbie question. What is the standard way of internally storing data attached to a listbox item. ie. I have a listbox which has user defined items that can be added deleted. For each of the items I need to display/store particular information. eg. On the left I have a Listbox containing account numbers and on the right I have edit boxes containing Name, Address etc. Can I use the Items.Objects property to link each item to another object in this case? Or do I simply store the Name/Address data in a string array indexed on the ItemIndex. That creates a problem when the user deletes an item from the list -- I would have to move the data around in the array which I would rather not do. Maybe I should use the item Tag property to store the index of the related array data. (BTW: The data will eventually be saved to a text file) You can link to another object. In one of my applications I needed to store an integer. I defined a type PLongInt as a pointer to a LongInt. In the code I then created a new instance of the type assigning it to a local variable, set its value to the number and then assigned it to the Data property of the TListView. That's a little different but not much. All you need to do is: * Create a new instance of an object with a local variable * Assign that instance to the Objects property that corresponds to the list item. Since everything descends from TObject it is a simple assignation. * When you retrieve the object you will need to typecast it to the original object type otherwise you will not be able to access any properties or methods other than those in TObject. --- New Zealand Delphi Users group - Delphi List - [EMAIL PROTECTED] Website: http://www.delphi.org.nz To UnSub, send email to: [EMAIL PROTECTED] with body of unsubscribe delphi
RE: Listbox items (Was: Re: [DUG]: array of TStringList)
Some understanding here is useful.
It is not possible to create numerous objects with the same name.
When you create an instance of a class (an object) you are doing several
things:
1. Delphi reserves some memory for you
2. Delphi gives you in the variable on the left hand side, a reference to
that piece of memory.
If you then create another instance of the object using the same variable
name, you have lost access to the bit that you had before. it is still there
but you have no way of accessing it, because the variable now points to the
new bit you got. You can do this ten times but at the end you will still
only be able to access the last bit.
To get around this little problem when you need to keep lists of objects
created dynamically, Delphi provides the TList class. You can use a TList or
make a derivative from it. It would be usual to override the destructor to
ensure all the memory is freed in your objects.
Now, when using a TList the above steps become:
1. Delphi reserves some memory for you
2. Delphi gives you in the variable on the left hand side, a reference to
that piece of memory.
3. You add the value of that variable to a TList object.
Then you can use the methods of TList to access all those dynamic objects
you have created. In the days before OO we used to use linked lists of
pointers to do the same thing. Compared to that a TList is a doddle.
Addressing to your particular situation. A record is not an object. A
Tobject is an object.
I used to use records until I discovered how to use TList to link a whole
lot of dynamically created objects. To give an example I have just updated
an application that uses counters to count numbers in a big report, and do
various calculations etc. It used to use various TStringLists to store all
the counters. I updated it to use OO stuff. This is good because there are
two different types of counter and one is a subclass of the other.
All you have to do is:
* Create an instance of your object e.g. MyObject := TMyObject.Create
* Do something with it...set the fields or something
* Add it to the Objects property of the list box items (which is probably
implemented as a TList) . No typecast needed since everything is descended
from TObject.
Now you can safely reuse MyObject to create another instance, as the
reference is now saved in the list box. (Don't free it though, as it still
points to an instance, but if you wish you can set it to nil without
affecting any instances of your object)
When you have to do something with your object, it looks like this:
MyObject := TMyObject(ListBox1.Items.Objects[X]
You have to typecast it because Delphi stores it as a TObject and won't let
you access any of the methods or properties other than for a TObject, if you
don't do the typecast, also you will get an invalid type error from the
compiler.
Note that the Objects property still contains the reference until that list
item is deleted.The question I am not at all sure about is whether Delphi
frees the memory associated with each object reference when the list item is
removed from the list.

Heres some really quick dirty code to throw some light on the

Records as objects
TMyRec = record
Name: String;
Age: Integer;
end;
pTMyRec = ^TMyRec;
procedure TForm1.Button1Click(Sender: TObject);
var
MyObj: TObject;
MyRec: TMyRec;
PMyRec: pTMyRec;
Z: pTMyRec;
begin
MyRec.Name := 'NIRAV KAKU';
MyRec.Age := 22;
// record to object
PMyRec := @MyRec;
MyObj := TObject(PMyRec);
// object to record
Z := pTMyRec(MyObj);
// testing results
ShowMessage(TMyRec(Z^).Name);
ShowMessage(IntToStr(TMyRec(Z^).Age));
end;
Records save memory.
Hope this helped.

RE: [DUG]: Multi Monitors
How do you force the form to either monitor 1 or 2? I know there are two monitors in the system having tested at runtime. I have my form maximised, and hidden, DefaultMonitor will be the same as main form (monitor 0). The Monitor property of the form is read only (tells you which monitor it is on) so the only way seems to be to set the left of the form to appear on whichever monitor. I thought this would work: //Go to monitor 0 PlayerForm.Left := Screen.Monitors[0].Left; //Go to monitor 1 PlayerForm.Left := Screen.Monitors[1].Left; Assuming that the monitor's left property is where on the desktop it appears. Is it because it is already maximised that it refuses to move? Maybe to minimise or restore it first before moving it? Or am I totally on the wrong track? -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Ben Taylor Sent: Monday, 2 July 2001 17:33 To: Multiple recipients of list delphi Subject: re: [DUG]: Multi Monitors Hi, it probably depends what setup they're running. i'm using a matrox g400 dual display, nt2k, with the matrox drivers and utils. with the options i have set, the form maximises to the screen its (mostly) contained in, but it can be forced to either display 1 or 2.. the display itself appears as 2048x768, so anything with x1024 is on the second display. hope that adds to the confusion :-) Ben. __ Do You Yahoo!?

How does one position a form of an app to appear on the second monitor, and be maximised on that monitor? The main form will appear on the primary display.

Dependency Walker is a useful free tool from MS that lists the dependencies of a module (application etc) i.e. all DLLS and other files referenced by an app. Good if you are having problems with files missing on some computer system. http://msdn.microsoft.com/library/techart/redistribvc6.htm === Patrick Dunford, Christchurch, NZ - http://pdunford.godzone.net.nz/ For I am the LORD, your God, who takes hold of your right hand and says to you, Do not fear; I will help you. -- Isaiah 41:13 http://www.heartlight.org/cgi-shl/todaysverse.cgi?day=20010227 === Created by Mail2Sig - http://pdunford.godzone.net.nz/software/mail2sig/ --- New Zealand Delphi Users group - Delphi List - [EMAIL PROTECTED] Website: http://www.delphi.org.nz To UnSub, send email to: [EMAIL PROTECTED] with body of "unsubscribe delphi"

RE: [DUG]: Software Expiry Codes - OnGuard
If you are encrypting keys then it seems to me that you are also including in some form, the code that will encrypt and decrypt them in your application.At what point can a hacker discover the code in your application that enables them to decrypt your keys? -Original Message-From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of David BrennanSent: Wednesday, 21 February 2001 09:26To: Multiple recipients of list delphiSubject: [DUG]: Software Expiry Codes - OnGuard Hi, I am about to implement security codes which verify the user/site is allowed to run my software. I am envisaging that each site will be given a code and each code will be built using the site/company name and an expiry date. Thus the code won't work if the site name is different, nor will it work after the expiry date (naturally it also won't work for a different product). OnGuard from TurboPower provides exactly these features. As far as I can see it works as follows: You embed a unique and private product key in the application. The user enters the code they obtained for their product. The application checks the code by building a new code from the product key, site name, expiry dateand checks it against the code the user entered. If they match then everything is OK. My problem with this is that the product keys need to be embedded in the application. With these keys and their own copy of OnGuard a user/hacker could build their own valid codes for any site name or expiry date. I don't know how hard it would be for a hacker to extract the keys from an application (the recommended approach for embedding them would appear to be constants of type TKey which is a 16 bytebinaryvalue) but I suspect it wouldn't be too hard. Has anyone considered this issue before? Is there a way of encrypting the keys in the executable so that they areharder to obtain or doesDelphimake it hard enough as it is?Or is there a better tool than OnGuard out there?

Okthanks for pointing out the obvious
:)
What II am really looking for, is what kind of list I
should use.
I am figuring I will need to do something like
list.addobject('blah',pointer(datenumber))
But what list can I use or would be best to use that
i can sort by the datanumber ? (other than a
TListview)

Once you have the date as a TDateTime you just need
to sort it on a straight numerical basis.

all.
This is

What I have is
a dir that has files in it with names that are unique.What I need to

Does anyone
have any bright ideas on the best way to do this ? It woudl need to be

RE: [DUG]: sorting files
TdateTime is a real type, and is the number of days from a certain point. Thus a simple numerical sort will do the job. -Original Message-From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Nello SestiniSent: Friday, 9 February 2001 22:05To: Multiple recipients of list delphiSubject: Re: [DUG]: sorting files I didn't think it was that obvious - one could easily be tempted to write a complicated date sorting routine... I didn't think it was obvious either. there was a Delphi version change a (long) while back where the date format changed - so that if you had apps from different versions passing binary dates around (a bad idea certainly) you COULDN'T just compare them as integers. -ns

This is the code I use in Delphi 3. It may be different in later versions. if ((SourceType = '.JPG') or (SourceType = '.JPEG')) then begin JpegImage := TJpegImage.Create; JpegImage.LoadFromFile(ImageFile); SourceImage.Picture.Assign(JpegImage); SourceImage is a TImage control.

This works file with *.BMP files, but don't seems to work with *.JPG files.

The BMP file get loaded and shows correctly, but the JPG file returns the following message when loaded into the TImage: "Unknown picture file extension (.JPG)" Any idea? Thanks for your help.

RE: [DUG]: TDataSet descendant
If you are using some versions of Delphi you have TClientDataSet, which itself is a TDataSet descendant For other versions you could presumably override the virtually declared methods in TDataSet, but I don't have any references for this.
