I'm new to DNN programming, acctualy this is my first project. I'm not new on APS.NET, C#, VB and SQL but still I have some problems to set up my development environment. I have been googling and reading forums/manuals but I cannot seem to find an answer to my problems.

The situation is this: I bought a module online (with source) and now I would like to add 3 custom fields. I have a local iis and db and the site is installed there without errors. I have also installed the module which works fine now. Then I opened the inetpub folder with visual studio and started modifiing the files. Changes to the aspx files seem to work as they should. Changed I made tot he vb files do not work. I even put text in an existing textbox which should be plain and simple, but it's not executed.

One important remark, in the downloaded source files is no solution or project, just aspx, vb, config, dll, .. files.

So when I was thinking this through these were my unanswered questions so far:
- Does installing the source zip makes the vb files all stand in the right place automatacally?
- Do I have to make some settings to use these VB files?
- Can I just hook my visual studio to the inetpub folder and start developping?
- How do I rebuild so my code changed are used on the site?
- When I now debug from vs, it does'nt jump to code files, although I think this is related to the above questions.
- Am I correct when I say: when i extract the module on the site itself I can use that extraction to install the module on the PROD environment?

I hope someone can help me with this (I think simple questions for not newbies)? If I skipped a manual/site then I'm sorry to have asked the questions, but I didn't found any that helped me with this perticular case.

Thanks for any help!
