Plugin Developer Discussion

Am stuck on a NullReferenceException and not sure how to track it down.

Is there any way to run a remote debug session or at least pump out some log messages to a console?

Any help would be appreciated.

Thanks.

For fun, here's my stack trace ;-)

I figured out my particular error; it appears I'm not supposed to use DateInput.

Would still be nice to have access to some debugging tools however.

Thanks.

You should be able to use DateInput.  Can I ask what you traced the error to?  It's entirely possible that the bug is in our code.

As far as debugging goes, the Visual Studio debugger should work.  If you're developing on a local FogBugz install, you can do the following:

1. Build your plugin in Debug mode
2. Upload it to FogBugz and hit a page to make sure it is loaded
3. In Visual Studio, under the Debug menu select "Attach To Process"
4. Make sure "Attach To" has "Managed Code" enabled
5. Select your ASP.NET/IIS process, probably either "w3wp.exe" or "aspnet_wp.exe"
6. Right click on a line and add a Breakpoint

I haven't tried debugging remotely, but there are lots of resources on the internet for setting up remote debugging of IIS with Visual Studio.

Let me know if you are unable to get this working and I'll try to help.

Shoot, remote debugging not supported with C# express edition.

Regarding DateInpputField, I was calling as follows:

string startInput = FogCreek.FogBugz.UI.Forms.DateInputField("start", "start", "2009-06-01");

It certainly looks like an error in our code.  I've opened a case.
