Hi

You use the MessageBoxIndirect api call.

Steps:

1.  Create a .res file (with Image Editor).
2.  Add a new 32*32 icon.  Give it an Integer name (in my e.g. below I called it 123).
3.  In your form add {$R MyRes.res}

4.  The following code uses the icon in MyRes.res:

procedure TForm1.Button1Click(Sender: TObject);
var
  MBParams: TMsgBoxParams;
begin
  FillChar(MBParams, SizeOf(TMsgBoxParams), 0);
  MBParams.cbSize := SizeOf(TMsgBoxParams);
  MBParams.hwndOwner := Self.Handle;
  MBParams.hInstance := hInstance;
  MBParams.lpszCaption := 'My Caption';
  MBParams.lpszText := 'This is my message.';
  MBParams.dwStyle := MB_USERICON;
  MBParams.lpszIcon := '#123';    // Icon resource number.
  MessageBoxIndirect(MBParams);
end;


Regards,
JB

I sure do.

What ver of Delphi are you using?
Did you use Image Editor?
Is your icon called (e.g.) "123" and you load it with #, i.e. '#123'?

I work with Delphi 3.0.
Yes, I did everything you said.
Can you copy your source from here to your program and see if this is working? I have had a case where copy and paste didn't get the code to work just rewriting it.

Mmm...  I also use Delphi 3.

Steps 1, 2 & 3 are not code-based.  With Step 4 I did copy & paste.  I can e-mail you the sample if you want me to.

Ok, I have checked it and..
It works great in 95, but not in NT, and I work only with NT. If you see the API help, then in the QuickInfo popup message you'll see that they say
Windows NT    stub
Win95         Yes
I don't know what it means, Do you?
Do you know of another API call to a custom message dialog?

I'm not sure what "stub" is, but try replacing:
  MBParams.lpszIcon := '#123';
with:
  MBParams.lpszIcon := MakeIntResource(123);

Does "MakeIntResource(123)" work on your PC?  I've just tested it on an NT machine and it worked...

Yeah, I commented before I saw the answer...  Glad it works.  We learn something new everyday.  I've just changed my CustomMsgBox routine to use MakeIntResource.  I never knew it didn't work on any NT 4 machines until now!

If I use   MBParams.dwStyle := MB_USERICON+MB_YESNO
then how do I know which button was pressed, Yes or No?

Good question.  It took me a while to work this one out!  MessageBoxIndirect returns a boolean value, but it's actually an integer value.  You need to type-cast the bool to an integer.

E.g.  AInt := Integer(MessageBoxIndirect(MBParams));

AInt will then contain IDYES, IDNO, etc...
