- hWnd IntPtr
-
A handle to the window and, indirectly, the class to which the window belongs.
- flags WindowLongValues
-
The zero-based offset to the value to be retrieved.
Valid values are in the range zero through the number of bytes of extra window memory,
minus the size of an integer.
UInt32
If the function succeeds, the return value is the requested value.
If the function fails, the return value is zero.
If
SetWindowLong(IntPtr, WindowLongValues, UInt32) has not been called previously,
GetWindowLong(IntPtr, WindowLongValues) returns zero for values in the extra window or class memory.
