Ok I did some researching on what you said... and I found out that I could retrieve window styles as well as extended styles by using GetWindowLong(HWND hwnd, int nIndex) which returns long. However I also remember that window styles(as well as extended ones) can be combined by a "|". No wonder the following statement(s) would return false for any values of hwnd passed through EnumWindowsProc when I call EnumWindows:

BOOL IsAppWindow(HWND hwnd) {
   if (GetWindowLong(hwnd,GWL_EX_STYLE)==WS_EX_APPWINDOW) {

      return true;

   } else {

      return false;

   }
}

Did I do something wrong? If there is, please tell me. The function is supposed to detect if a handle refers to a window with the WS_EX_APPWINDOW style. Note the word WITH which not necesarilly means "ONLY". So how do I get around this problem?

Note:
   I have Dev-C++ and Win32 help up and running on my computer while I was running the program with the afformentioned function. I tried to count the number of windows with WS_EX_APPWINDOW extended style. But I always end up with 0. I'm expecting to get an output of greater than 0. How do I get around this problem?

You could AND the value you want to test for against the value returned -


if ((GetWindowLong(hwnd,GWL_EX_STYLE) & WS_EX_APPWINDOW) == WS_EX_APPWINDOW)
