No code example is currently available or this language may not be supported.
- 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 32-bit 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 four; for example, if you specified 12 or more bytes of extra class memory,
a value of 8 would be an index to the third 32-bit integer.
- newValue UInt32
-
The replacement value.
UInt32
If the function succeeds, the return value is the previous value of the specified 32-bit integer.
If this was not previously set, the return value is zero.
If the function fails, the return value is Zero.
