If you're lazy, like me, and can't be bothered with all that 'RegisterClass' and 'CreateWindow' rubbish, or you want to create a window that's based on a dialog box template (like most of the wizardy stuff that's about now) then you'll know that as standard you just get the cacky little 'flying windows' icon. Here's how you change it. The web demo applet's got a better example of this in it.

... HICON hIcon ... int WINAPI WinMain(...){ ... hIcon=LoadIcon(hInstance,MAKEINTRESOURCE(IDI_MYICON)); DialogBox(...(FARPROC)DialogProc...); DestroyIcon(hIcon); ... } BOOL CALLBACK DialogProc(...){ ... case WM_INITDIALOG: ... SetClassLong(hWnd,GCL_HICON,(LONG)hIcon); ... break; ... } ... |

And that's all there is to it. Define a global icon handle, load this at the start of WinMain and destroy it just before the end. Then, in each WM_INITDIALOG message handler do a SetClassLong. Bargain. I think this might change the icon for all dialog windows of the current task, never mind, you can't have everything can you.
