Post a Comment On: Win32 Coding

The MSDN documentation says that SetWindowLong is deprecated (it didn't use that exact word) and should be replaced with SetWindowLongPtr instead to work with 64-bit versions of Windows. I thought I'd try it out and did the following:

LONG appWindowExStyle = WS_EX_APPWINDOW;
SetWindowLongPtr(hwnd, GWL_EXSTYLE, (LONG_PTR) &appWindowExStyle);

It didn't seem to work. However, the old 32-bit way seems to work fine:

SetWindowLong(hwnd, GWL_EXSTYLE, WS_EX_APPWINDOW);

I guess it's one of those things that I ought to investigate further.
