在WM_PAINT消息中绘图,图片没显示出来

[tx183584]

不是在MFC中

	case WM_CREATE:
		hInstance = ((LPCREATESTRUCT) lParam)->hInstance ;
		//加载位图，位图已经被添加成资源 
		hBitmapImag = LoadBitmap (hInstance, _T("IDB_BITMAP2")) ;
		//获得位图结构
		GetObject (hBitmapImag, sizeof (BITMAP), &bitmap) ;
		//位图的宽度和高度
		cxBitmap = bitmap.bmWidth ;
		cyBitmap = bitmap.bmHeight ;
		break;
	case WM_SIZE:
		cxClient = LOWORD (lParam) ;
		cyClient = HIWORD (lParam) ;
	case WM_PAINT:
		hdc = BeginPaint(hWnd, &ps);
		// TODO: 在此添加任意绘图代码...
		//创建兼容内存DC
		hdcMemImag = CreateCompatibleDC (hdc) ;
		//将位图选入内存DC
		SelectObject (hdcMemImag, hBitmapImag) ;

		//计算居中显示的位置
		x = (cxClient - cxBitmap) / 2 ;
		y = (cyClient - cyBitmap) / 2 ;

		//将内存DC拷贝到客户区DC
		BitBlt (hdc, x, y, cxBitmap, cyBitmap, hdcMemImag, 0, 0, SRCCOPY) ;

		//删除内存DC 
		DeleteDC (hdcMemImag) ;

		EndPaint(hWnd, &ps);
		break;

你看看 hBitmapImag = LoadBitmap (hInstance, _T("IDB_BITMAP2")) ;
这里的图片句柄是否为空？
应该这么写吧：
hBitmapImag = LoadBitmap (hInstance, MAKEINRESOURCE(IDB_BITMAP2)) ;

[Mdesigner]

看下是否调用到绘制部分了，还有区域是否正确

[wltg2001]

hBitmapImag = LoadBitmap (hInstance, _T("IDB_BITMAP2")) ;
==========
看看这个有没有成功
一般的写法是
hBitmapImag = LoadBitmap (hInstance, MAKEINRESOURCE(IDB_BITMAP2)) ;
