I saw in MSDN EnumerateMetafile is called in OnPaint method of a Form
control.

How to make the following code works? Can anyone help?

Graphics g = this.CreateGraphics();
Graphics.EnumerateMetafileProc metafileDelegate =
new Graphics.EnumerateMetafileProc(MetafileCallback);
g.EnumerateMetafile(file, new Point(0, 0), metafileDelegate);
g.Dispose();
