I downloaded the chapter 7 project of Professional SQL Server Reporting services. I am able to build the solution but when I click the Go button on the main form, it gives the following error:
An exception has occured: Object reference not st to an instance of an object.

Thanks in adavance

You probably have an object variable that hasn't been instanciated. You are probably missing a New keyword somewhere. What does the code look like and what like is blowing up?

This is happening with the code I downloaded from this web site. I did not make any modifications. This is Chapter 7 code "Managing Reports using Program Code". When I step thru the code, it breaks in GetServerFolders() in Mainform.cs at line
items = rs.ListChildren("/", true);

I hope this helps in identifying the problem.

I downloaded the code and ran it with same bug...here is how to fix it.

Go to Solution Explorer and expand the Web References folder. Right click the ReportingWebService item. On the pop up menu, click, Update Web Reference. That's it! Recompile or Debug the program and it will work. Hope this helps.:) Jesse
