Question

My boss has asked me to set up DotNetNuke’s Survey Module and make a few custom changes to it for a client. But I’m having trouble just getting the bare-bones code to run properly!

Here’s what I’ve done so far:

1. Downloaded both the source & install folders from
   http://dnnsurvey.codeplex.com/releases/view/65186
2. Created a new VB Web Application Project
3. Took out all the default pages
4. Copied the Survey source code into the VB Web Application Project in exactly the same structure
5. Made a batch script that creates an installation folder identical to DNN’s install folder (double-checked by running a folder-diff on it, and all files/folders were identical)
6. Zipped up my installation folder using 7-zip

The source code compiles perfectly. But even though the files/folders are identical, DNN’s zipped package will work properly on my DNN site, and my own zipped package will fail with this famous error message:

Error: Survey is currently unavailable.

I’ve already asked about this on the DNN forums, but they don’t have much to say about it 🙁 So, I thought I’d try StackOverflow as well.

Does anybody have any idea what the problem could be? Thanks very much in advance!

Answer 1

I ended up solving this one on my own. These are the steps I took:

1. Removed all Namespace DotNetNuke.Modules.Survey declaractions
2. Deleted the ascx, ascx.vb, and designer files for survey, Settings,
   and EditSurvey
3. Created new, empty ones with those names (but used “Survey” instead
   of “survey”)
4. Copied/pasted the ascx code into each ascx file (and changed
   DotNetNuke.Modules.survey to DotNetNuke.Modules.Survey)
5. Did a build
6. Copied/pasted the ascx.vb code into each ascx.vb file (and removed
   the Namespace declarations in these files)
7. Did a build, which was 100% successful this time

Bizarre way to solve the problem, but it worked. :3
