Can anyone tell me if there is an OS/2 Presentation Manager C/C++ 
equivalent of the following Windows MFC / Windows API snippet of code?
What I want to do is define an "empty" icon on an OS/2 P.M. dialog box,
then depending on the menu item / toolbar button that the user chooses,
send a certain ICON to the dialog box. I would send different icons,
depending on the menu item the user picked. In my MFC code, it goes something
like this...

// MFC Code

LPCSTR IdIconResource;
HICON hicon, hiconOld;
HINSTANCE TestInstance;

TestInstance = AfxGetInstanceHandle();

IdIconResource  = MAKEINTRESOURCE(IDR_ICON);
hicon = LoadIcon(TestInstance,IdIconResource);
hiconOld = (HICON)SendDlgItemMessage(IDR_NEWICON, STM_SETICON, 
                                     (WPARAM)hicon, 0);


Someone on Internet suggested using WinLoadPointer() to load
an icon from the resources, but didn't provide any example code.
I wasted about two hours researching the Watcom online help and 
toying with code, but never could get anything to work. Any help
would be greatly appreciated. If you know of somewhere I can grab
source/examples (or an EDMI issue number), that'd help; or if you
can post a brief example here. Thanks.
