Syntax
Copy
public static IntPtr SetWindowLongPtr(
	IntPtr hWnd,
	int nIndex,
	IntPtr dwNewLong
)

Parameters

hWnd  IntPtr
A handle to the window and, indirectly, the class to which the window belongs.
nIndex  Int32
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 a LONG_PTR. To retrieve any other value, specify one of the JCWindowsManagerGWL values.
dwNewLong  IntPtr
The replacement value.

Return Value

IntPtr
If the function succeeds, the return value is the previous value of the specified offset. If the function fails, the return value is Zero. To get extended error information, call GetLastError.
Remarks
This static method is required because legacy OSes do not support SetWindowLongPtr
