cWinIdConvert

Convert between a Windows handle and a Window Id (pseudo-handle)

Syntax:

cWinIdConvert(window-id | window-handle)

Parameters:

(s/i) window-id or window-handle Window ID handle or Window handle.

Returns:

(s/i) window-id or window-handle Window handle, if parameter is a Window ID or Window ID, if parameter is a window handle.

You can use CWinIdConvert to convert between a Windows handle and a Window Id (pseudo-handle). If you pass in a Windows handle, the function returns the corresponding Window ID. Conversely, if you pass in a Window ID, the function returns the corresponding Window handle.

CWinIdConvert will error if the input value does not reference an existing window.
