I've learned quite a bit in this process, but now I've hit a sticking point.    I realize many folks are at Dev Connections this week, wish I were there. :)

I have Mitchel Sellers book and am following along with it.  I have the module written, compiled, and 'imported' into my development website.    When I add it to a page in Edit mode a rectangle displays with nothing inside.   When I try to access the settings page I get a small error message above the box "A critical error has occured.  Object reference not set to an instance of an object:    But of course I don't know which object reference it is referring to.

I am able to connect to the process and watch as the code in the page_Load event is run, so I know the website is able to find the module.  At the end of that code I have to click the run button to coninue and that is when the error comes up. 

Any clues at what I should look at/for?   Something in the markup maybe?   Is there a logging mechanism I can use to help determine where the problem is happening?     I like what I've seen in DNN since I last looked at it, and would like to use it in our company but I need to be able to add our own code/data to the system. :)

Thanks in advance for any tips you can provide,
Lou

That got me on the right road, thanks!    Turned out the problem was in the manifest.    Had a few other things, but they were code related and I was able to track them down.

Thanks again for the assist!
