Answer 1

Or you can use EnableWindow with getting window handle if your dialog box that contains the control which need to disable:

EnableWindow(GetDlgItem(hwndDlg,BTN_TRIM),false); // to disable button or other control
EnableWindow(GetDlgItem(hwndDlg,BTN_TRIM),true);  // to enable button or other control

hwndDlg - A handle to the dialog box that contains the control
BTN_TRIM - The identifier of the control to be retrieved

Answer 2

To use Button_Enable macro, You need to insert

#include <windowsx.h>

in your header file.

Or, you can use EnableWindow() function:
