moriii,
Ah, been there...
There is no real easy way to compile the DNN solution using VBC alone. Believe me, we've tried to keep a simple vbc and rsp procedure available, but it's just not possible. Now, the alternatives are out there, and as a handcoder who came to DNN a couple of years back, I used Nant until recently. Nant is a simple compile tool that can be used to compile the DNN solution with an appropriate build file, which is similar to rsp type files. There was another free .Net compiler out there #develop, I believe, but I've never used it.
I've not used Nant to compile DNN recently, as I was lucky enough to get a free copy of VS2005 at the recent round of MSDN seminars, and had a freebie copy of VB.Net 2003, but I see a Nant build file in the root DNN folder of my local install, so it should be possible to do. I'd suggest getting the Nant distribution and work through it, building some examples, then try it with DNN. The quicker, but more expensive route is to get vb.net std and you'll be able to do it, if you can afford the whole VS app, it would be the ideal, as some modules are written in C#.
