Assign TForm.Icon at run time

Answer:

ImageEdit is not good. Try to get Borland's Resource Workshop or paint with 
paintbrush and use a freeware converter to convert from BMP to ICO, write a little 
resource script (*.rc) refering to the ICO file and compile it to *.res with 
BRCC.EXE (comes with Delphi).

Use {$R xxx.res} to include it. Then you may use the API function

1   HICON LoadIcon(
2     HINSTANCE hInstance, // handle of application instance
3     LPCTSTR lpIconName // icon-name string or icon resource identifier
4     );



Take this handle (HICON) with the message WM_SETICON to assign it to your form:

SendMessage(Form1.Handle, WM_SETICON, false, iconhandle);

Note: 3rd parameter = icon size (true -> large icon; false -> small icon).
