I've created a number of modules using that reference as a guideline. It's hard to say what's happening to your module without more information. Obviously you've built it running a source dnn install in visual studio. Were you able to install the module to DotNetNuke OK so that it shows up in your module dropdown list? If that's the case then probably the only way to solve the problem is by running it under visual studio in debug mode and walking through the code to see what's going on. I've had to do that quite a few times to get mine working correctly.

Sorry can't be much more help.

I'm not really sure what you are doing. Are you modifying the announcements and contacts modules to suit your installation or are you starting with them as a base to build your module?

First of all, I would never recommend modifying the DNN modules. Daniel Eagan's module building procedures were fairly easy to follow and resulted in my building solid modules. I'm not sure how you are crossing over to core modules but that could never lead to a good thing.

 If I misunderstood your intentions - sorry. Use the step-by-step procedures instead of trial and error and do not modify DNN core modules.
