Is there a way to update a dialog item in a CDialog (and on the screen) without calling UpdateData(false) ?

hehe
not only did I know the answer to this, i had already written the code to do it... i was just calling updatedate for no reason

    
			DWORD now = clock();
			DWORD elapsed = now - timesnap;
			timesnap = now;
			CStatic* fr = (CStatic*)GetDlgItem(IDC_STATIC_CLOCK);
			char stemp[80];
			itoa(elapsed,stemp,10);
			CString str("Elapsed: ");
			str += stemp + CString("ms");
			itoa(timer,stemp,10);
			str += CString("  Delay: ") + stemp + CString("ms");
			fr->SetWindowText(str);
			//UpdateData(false);

The correct method of doing this depends on the control you are updating. For instance, SetWindowText is a method to update edit control text without calling OnUpdate, but to update a CComboBox you would probably use SetCurSel or SetEditSel. Reference MSDN help for the item you wish to explicitly update.
