Function Reference


HWnd

Converts an expression into an HWND handle.

HWnd ( expression )

Parameters

expression An expression to convert into an HWND handle.

Return Value

Success: If the value can be converted to an HWND, the HWND representation will be returned.
Failure: If the HWND does not denote a valid window, a 0 (NULL) HWND will be returned and sets the @error flag to 1.

Remarks

Double numbers can not be converted to an HWND.
No literal string should be converted to an HWND because there is no guarantee that a given window will have the same HWND ever again. This is not strictly forbidden, but it is a programming mistake and should be avoided.
