    Posted: 22 January 2008 at 10:32am
I'm trying to disable the Close Button of the window frame in runtime using the following code:
 

void EnableCloseButton(BOOL bEnable)

{

UINT menuf = bEnable ? (MF_BYCOMMAND) : (MF_BYCOMMAND |

MF_GRAYED | MF_DISABLED);

CMenu* pSM = GetSystemMenu(FALSE);

if(pSM)

{

pSM->EnableMenuItem(SC_CLOSE, menuf);

}

}
 
 
I call this function on a button click. It works for a dialog based test application. In my application project based on CXTPDialogBase<CXTResizeDialog> the button is not disabled. When I maximize it the new style i applied to the button.
 
Is there a workaround for this problem?
Thanks,
 
Timo

Hi,
 
Try call
 
SetWindowPos(0, 0, 0, 0, 0, SWP_NOMOVE | SWP_NOSIZE | SWP_NOZORDER | SWP_FRAMECHANGED | SWP_NOACTIVATE | SWP_DRAWFRAME);
after.

That didn't work, but based on your answer I found the solution myself. I had to change the Window Style and then change it back to the old state to refresh the buttons. I chose the maximize button:
 
AfxGetMainWnd()->ModifyStyle(WS_MAXIMIZEBOX, 0, SWP_FRAMECHANGED);
AfxGetMainWnd()->ModifyStyle(0, WS_MAXIMIZEBOX, SWP_FRAMECHANGED);
 
Regards
