InfoPath Dev

Ok, what I want to do I think is very straight forward, but then again... maybe not.

I want to have my InfoPath form's document name to be based on a value of a field on the form for the initial save (This is going to a Form Library on SharePoint).  I also don't want to give the user to change it, unless they do "Save As". 

Field: ProjectName = "MyFirstProject"

Document Name = "MyFirstProject.xml"

 I used to do a lot of VB coding back in the day, and think that this is possible.  I can do this in Visual Basic or C# if someone can give me some direction.

 BTW, this is InfoPath 2007 on a WSS 3.0 site.

 Thanks!

try creating a custom save button and write following code on it

this.save(desired form name);

that should help
