  一、用VC編寫(xiě)基于對(duì)話框的應(yīng)用程序，用BMP位圖作為對(duì)話框背景，對(duì)話框上的STATIC靜態(tài)文本框，可以用以下消息函數(shù)使文本框的文字背景透明：  

        HBRUSH CXXXDlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
        {
                HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);

                // TODO: Change any attributes of the DC here
                if( nCtlColor == CTLCOLOR_STATIC)    
                {  
                        pDC->SetBkMode(TRANSPARENT);   //設(shè)置背景透明
                        return   HBRUSH(GetStockObject(HOLLOW_BRUSH));    
                }  

                // TODO: Return a different brush if the default is not desired
                return hbr;
        } 

        二、動(dòng)態(tài)改變控件文本內(nèi)容時(shí)閃爍，可以用以下函數(shù)解決這個(gè)問(wèn)題：

         void   CXXXDlg::OnBtnStatic()    
        {  
                //   TODO:   Add   your   control   notification   handler   code   here 
                //    IDC_STATIC_ST為靜態(tài)文本控件ID號(hào)  
                CStatic*   pSt   =   (CStatic*)GetDlgItem(   IDC_STATIC_ST);  
                pSt->SetWindowText("北京2008");  
                RECT   rect;  
                pSt->GetWindowRect(&rect);  
                ScreenToClient(&rect);  
                InvalidateRect(   &rect,FALSE   );  
                //Invalidate(FALSE);   //  整個(gè)客戶區(qū)無(wú)效  
        }
