The GetWindowWord function retrieves a 16-bit (word) value at the specified offset into the extra window memory for the specified window.

Declare Function GetWindowWord Lib "user32" Alias "GetWindowWord" (ByVal hwnd As Long, ByVal nIndex As Long) As Integer

Operating Systems Supported
Requires Windows NT 3.1 or later; Requires Windows 95 or later


Parameter Information
- hWnd
Identifies the window and, indirectly, the class to which the window belongs.

- nIndex
Specifies the zero-based byte offset of the value to be retrieved. Valid values are in the range zero through the number of bytes of extra window memory, minus two; for example, if you specified 10 or more bytes of extra window memory, a value of 8 would be an index to the fifth 16-bit integer.

Return Values
If the function succeeds, the return value is the requested 16-bit value.

If the function fails, the return value is zero. To get extended error information, call GetLastError.
