前两天做都还没有问题的，今天启动工程，运行的时候不是出错，而是IDE整个死掉。于是我就在整个程序开始的地方开始调试，发现到了GdipTranslateRegion VolumeBarBregion, (X - xl) * 1.03, 0时就会死掉。也不知道为什么。我是将GDI+用到控件设计中，下面的代码是绘制界面的。按道理来说在用GdipCreateFromHDC函数创建一个graphics对象之后，只要这个对象不被销毁，在后续的绘图中就应该可以一直使用它。但实际上却不行，每一次绘图都要重新调用GdiplusStartup函数和GdipCreateFromHDC函数，不调用的话就画不出任何图像（在下面的代码中，有一个Terminate子程序，里面的GdipDeleteGraphics graphics语句即使去掉也不行)。也不知道为什么。

你的代码我没有看到运行了 GdiplusStartup gToken, GDIsi 这个启动命令，该命令gdi+中是必须的
GdiplusStartup
结束的时候使用
GdiplusShutdown 两者之间进行输出操作啊
FYI: GDI+ Crash in IDE
