I have not tried to do exactly what you have suggested, but soemthing similar based on another post here - but ran into a problem that MsgBox is not a valid function outside of the Visual Studion IDE. In fact, for my test project, the MsgBox option was showing up wonderfully in the "preview" mode, but stopped displaying it in the "Debug" mode. Needless to say, deploying it to the Reporting Server also did not help - it apprears that the VB Code for MsgBox is simply Not Supported on SSRS Servers. Read this[/url]

May be I am wrong, in which case, I would be very happy to find out how you got your solution to work on the SSRS Server.
