- hWnd HandleRef
-
A handle to the window and, indirectly, the class to which the window belongs.
- value ClassLongValues
-
The value to be replaced.
To set a value in the extra class memory, specify the positive,
zero-based byte offset of the value to be set.
Valid values are in the range zero through the number of bytes of extra class memory, minus eight;
for example, if you specified 24 or more bytes of extra class memory,
a value of 16 would be an index to the third integer.
- newValue IntPtr
-
The replacement value.
IntPtr
If the function succeeds, the return value is the previous value of the specified offset.
If this was not previously set, the return value is zero.
If the function fails, the return value is
Zero.
