然后显示图片需要写在WM_PAINT消息里：
首选使用函数LoadImage载入位图或图标。
hb_icon = (HBITMAP)::LoadImage(hInst, _TEXT("icon.bmp"), IMAGE_BITMAP, 36, 36, LR_CREATEDIBSECTION | LR_DEFAULTSIZE | LR_LOADFROMFILE);
HDC hMemDC = CreateCompatibleDC(hdc); //创建内存DC
::SelectObject(hMemDC, hb_icon); //把位图选进内存DC
BitBlt(hdc, 0, 0, 35, 35, hMemDC, 0, 0, SRCCOPY); //内存DC映射到屏幕DC
