How can I read a *.msg file inside VB ?

I have an application that save a Outllok message in *.msg files, then, the app store this messages in a single file for security and compression purposes. When I need to view the msg, I save the file to disk an open, but the interface of Outlook is always displayed.
I don't know how can I open this file in a object inside a vb form, and outside a outllok folder.
Someone help me?

Thanks,
