通过WM_CTLCOLOREDIT 控制EDIT控件外观

在建立一个对话框窗口之后通过拦截WM_CTLCOLOREDIT返回用CreatePatternBrush建立的画刷.之后EDIT控件画刷就会用该画刷中所加载的图片平铺整个控件所在区域.当然需要把wParam所指向的HDC通过SetBkMode设置为透明模式

 

 

static LRESULT MyDeskProc(HWND hwnd,UINT message,WPARAM wParam,LPARAM lParam)
...{
#define ICON_SIZE 96
    static POINT icoPos;
    static dx=13,dy=7;
    switch(message)...{
    case WM_KEYDOWN:
        switch(wParam)...{
        case VK_MENU:
        case VK_F1:
            CreateMainMenu();
            break;
        case VK_RETURN:
            CreateFavoriteWnd();
            break;
        case VK_UP:    
            CreateEPGPFWnd();
            //CreatePFWnd();
            break;
        case VK_ESCAPE:
            //DoPropertySheet(hwnd);
            break;
        }break;
    case WM_COMMAND:
        switch(wParam)...{
        case 100:CreateMainMenu();break;
        }
        //SetCursorPos(LOWORD(lParam),HIWORD(lParam));
        break;
    case WM_CTLCOLOREDIT:
        ...{
            static HBRUSH hb=0;
            extern HINSTANCE hInstDVBRes;
            if(hb==0)...{
                HBITMAP b=(HBITMAP)LoadImage(hInstDVBRes,0x05,IMAGE_BITMAP,0,0,0);
                hb=CreatePatternBrush(b);
            }
            SetBkMode((HDC)wParam,TRANSPARENT);
            return hb;
        }

    case WM_DESTROY:
    case WM_CLOSE:break;
    default:
        return DefWindowProc(hwnd,message,wParam,lParam);
    }
}
