Show Help Button in the Title-Bar of the Window

Question

Is there any way to show the (?) Help button in the TitleBar. This button should be place nearer to the minimize button

The Help icon (?) is only there when HelpButton = True and MaximizeBox and MimizeBox are both set to False. This is the windows standard. If you really want to go beyond and add a button anyway you'll have to customize the titlebar. A workaround is to provide your own button to trigger the same action. Put it somewhere close to the upper right corner. You trigger this by sending yourself a WM_SYSCOMMAND message just like the standard help button does. private void Help_Click( object senderEventArgse){ Help.Capture= false ; SendMessage( this .HandleWM_SYSCOMMAND(IntPtr)SC_CONTEXTHELPIntPtr.Zero); } private const int WM_SYSCOMMAND=0x112; private const int SC_CONTEXTHELP=0xf180; [System.Runtime.InteropServices.DllImport( user32.dll )] private static extern IntPtrSendMessage(IntPtrhWnd int msgIntPtrwpIntPtrlp);
