FormWndHnd

Gets the window handle for the given form. The window handle may be used by 'C' programs and Plant SCADAWnd... functions. You should call this function only after the FormRead() function.

The window handle is not the same as the Plant SCADA window number and cannot be used with functions that expect the Plant SCADA window number (the Win... functions).

Syntax

FormWndHnd(hForm)

hForm:

The form handle, returned from the FormNew() function. The form handle identifies the table where data on the associated form is stored.

Return Value

The window handle if successful, otherwise a 0 is returned.
