embedding a button in reporting services

Example:
I want to add a button to my reporting services, when clicked on shows a VB.Net form and lets the user select a specific account(accounts) from my SQL Server 2000 table. After user selects a specific account, the form disappears, and the selected account appears in the account parameter textbox on reporting services report...

I have seen this done, but am unable 2 find any helpful stuff on the net. Can anyone explain how this is done, or if they know of any useful links?

I am using Visual Studio .Net 2003


Thanks.

Just check the crystal report parameter at my signature do you want this.?

no i am using Reporting Servces not Crystal Reporting.. my understabding is they are 2 completely seperate fings?!
