WM_SETICON

Dec 5 2003 7:49 AM
Hi, I have come across a puzzling problem with regard to using the WM_SETICON message to set the big and small icons associated with an application. My code works exactly as expected when running the application under Windows XP but does not work when running the same application under Windows 2000. I only use ICON_BIG and ICON_SMALL when sending the message as I am aware that ICON_SMALL2 is for XP use only. When running the application in Windows 2000, the code only manages to change the big icon which is displayed on the ALT + TAB dialog. Is this an issue with Windows 2000 or a problem with running .NET applications under Windows 2000? Thanks in advance. D.
