您需要为增强型元文件创建设备上下文，然后您可以使用MetaFile设备上下文.您将要使用与您要绘制的内容兼容的设备上下文，例如从GetDC或BeginPaint调用获得的Window DC.

You will need to create a Device Context for an Enhanced Meta-File, then you can draw on the MetaFile Device Context. You will want to use a device context that is compatible to what you want to draw from, such as a Window DC from a call to GetDC or BeginPaint.
