Q: How to enable/disable the 'Close' button of your dialog at run-time?
A:
<br><br>Code:BOOL bEnable = TRUE; // To enable
BOOL bEnable = FALSE; // To disable
UINT menuf = bEnable ? (MF_BYCOMMAND) : (MF_BYCOMMAND | MF_GRAYED | MF_DISABLED);
CMenu* pSM = GetSystemMenu(FALSE);
if(pSM)
{
pSM->EnableMenuItem(SC_CLOSE, menuf);
}
