WINDOWS

Summary:

An application can use the GetWindow function to enumerate the windows

that have a specified relationship to another window. For example, an

application can determine the windows that are children of the

application's main window.

The GetWindow function returns NULL when no more windows match the

specified criteria. Given a window handle, hWnd, the following code

determines how many siblings the associated window has:

int CountSiblings(HWND hWnd)

{

HWND hWndNext;

short nCount = 0;

hWndNext = GetWindow(hWnd, GW_HWNDFIRST);

while (hWndNext != NULL)

{

nCount++;

hWndNext = GetWindow(hWndNext, GW_HWNDNEXT);

}

return nCount;

}
