Help! Can anyone give me a simple code about drawing Metafile (use the memorystream)?

[astcws]

I need to draw a metafile by using Memorystream. But I don't know how to do this. All sample I can find on the internet is C# or using Bitmap or using a real file. I hope I can draw it immediatelly on the form and don't have to use a file. I have studied it several days but I still don't know how to do this. Can any one give me a example? Just a simple one is ok. Like draw some words on the form, for example. I would very appreciate it if some one can help me this.
