RE: [Dev-C++] C++ dialog control

[Marc H. <ma...@e-...>]

Hi,
Use EnableWindow(HWND hWnd, BOOL bEnable) to enable and disable a window
(your button).
Use GetDlgItem(HWND hDlg, int nIDDlgItem) to get the HWND of the window
(button).

So,
	EnableWindow(GetDlgItem(hDlg, ID_OK), FALSE));

Where hDlg is the handle to the dialog, will disable the button.

Also, you should have only one DEFPUSHBUTTON, the one you want to be the
default button. The others should just be PUSHBUTTON.

Subject: [Dev-C++] C++ dialog control


I have created an OK pushbutton in a dialog box via a resource script =
(see
code below):=20
****=20
=A0=A0=A0 DEFPUSHBUTTON=A0=A0 "Start", ID_START_CALC, 255, 7, 50, 14=20
=A0=A0=A0 DEFPUSHBUTTON=A0=A0 "OK", ID_OK, 255, 27, 50, 14=20
=A0=A0=A0 DEFPUSHBUTTON=A0=A0 "Cancel", ID_CANCEL, 255, 47, 50, 14=20
****=20
I am trying to grey it out and disable it, from within a callback =
function,
while I carry out some calculations, and then enable it again when the =
calcs
are complete.=20
Does anyone know how to do this? I have tried SendDlgItemMessage with =
the
dialog's handle, the pushbutton's ID and various LPARAMs and WPARAMs but
with no success. I have also trawled www.msdn.microsoft.com but found no
suggestions.=20
