How to disable the system menu on the button and floating toolbar in the dialog box

1. There are two methods to close the button in the disallow dialog box.

The first method is implemented by using the number of ModiftMenu () Han:

CMenu * pMenu = this-> GetSystemMenu (FALSE );
PMenu-> ModifyMenu (SC _CLOSE, MF_BYCOMMAND | MF_GRAYED );

The second method is implemented using the EnableMenuItem () Han Number:

CMenu * pMenu = this-> GetSystemMenu (FALSE );
PMenu-> EnableMenuItem (SC _CLOSE, MF_BYCOMMAND | MF_GRAYED );

2. disable the system menu on the floating toolbar.

Create a CToolBar derived class CxxToolBar, and double-click the left button in the new class (CxxToolBar: OnLButtonDblClk (...)) and left-click (CxxToolBar: OnLButtonDown (...)) add the following code to the culvert:

If (IsFloating ())File: // jobThe device is floating
{
CWnd * pMiniFrame;
CWnd * pDockBar;

PDockBar = GetParent ();
PMiniFrame = pDockBar-> GetParent ();

File: // goIn addition to the System Menu
PMiniFrame-> ModifyStyle (WS_SYSMENU, NULL );

File: // heavyPaint Toolbar
PMiniFrame-> ShowWindow (SW_HIDE );
PMiniFrame-> ShowWindow (SW_SHOW );
}
