Let me clarify our Users module is a COPY of the existing (and in play) DNN Users Module. Some end-users of the site needed some control of user accounts, so a role was established for them to add, delete users, reset passwords, etc.
What has happened, obviously, since it was written in VB / DNN 4.9.x is that being forked off (there's a phrase that needs to be pronounced carefully) it is now out of sync with the current 7.2.x code, now in C#.
The fix was easy even without ASP.Net debugging -- old fashioned debugging worked. I used the lblChanged.Text property and ferreted my way through the issues.
I should be able to set up a vanilla DNN 7.x site and install the modules in it, for the purposes of having a site where debugging will work. FYI, the site was handed over to me with 2 ORM tools in it, DNN 4.9.x in May of 2009. Also ... precompiled code. Modules had to be made using the traditional 3-tier approach, etc. and the ORM tools were removed when the hop to 6.2 was done 2 years ago.
I know you have no advice for making a hop from VS 2008 to VS 2013 but wouldn't editing the .sln and .proj files be an alternative? Any KBs on those?
