How to replace save file dialog by using memory stream ?

From your code, it looks like that you use the save dialog to prompt the user to retrieve the full file path name and put that into a 'path' variable.

If you don't want to prompt the user, then set the 'path' variable programmatically. This seems kind of obvious, so maybe I am not understanding your question?
