I have built the Guestbook Module in VB and installed it in an instance of DNN 5.0.1 running on a local machine. The module throws an error and I would like to debug but the instructions in Chapter 9 to attach the Module to the Visual Studio Debugger are unclear.

Has anyone successfully debugged their Guestbook Module using Visual Studio 2008? If so, how did you do it?

Thanks for the help!

Ross,

With the IIS installed version of DotNetNuke running you can within VS select "Debug" -> "Attach to Process". The window that will appear will show you all running processes on your machine.

You will want to select the process for ASP.NET. If on Windows XP it will be aspnet_wp.exe (or similar). If on Vista it will be w3wp.exe

Now, you will want to set a breakpoint to be able to step through the code, just prior to the error. The reason for this is that if you are allowing DNN to log the error, it isn't unhandled, and will not cause an automatic break with the debugger.

Once you have setup the breakpoint simply go to the module and perform the action that was causing the error, the debugger should take you into your code to start stepping through the code.
