Use this routine to enable/disable a window (or control, like a session panel button).
Note: when windows or controls are disabled the ‘look’ of the disabled window or control is managed by the Windows operating system. So, for instance, if you disable a Uniface session panel control it does not go dim, but the button cannot be pushed and a tool tip is not displayed when the mouse passes over it. Please also see the documentation on MHWHIDE.
; disable the REMOCC button $50="Rem_occ.UPANEL.A Test Application" perform "_getowhnd" if ($status < 0) done $52=0 ; ie: disable perform "_mhenable"
This function is only available under Win32 platforms (ie: Windows 95/98/ME and NT/2000).
