    Hi, 

    I'm trying to reuse an old DNN code written in VB but I receive this message:

    DotNetNuke.Services.Exceptions.ModuleLoadException: 'Visual Basic' is not a supported language.

    But in Extentions > Create new module 

    there is the possibility to select Visual Basic as language.

    I really need to convert my module from VB to C#?

    Thanks

      Yes, you can still use VB to write modules.

      It has been a while, but I'd guess that there is some configuration item that is not set. Possibly something in web.config?

      Are you doing this as a compiled module or an uncompiled one?

        This is a good news!
        My module is not compiled. I'm writing it into the editor. But which could be the problem in web.config? My module doesn't use any configuration.

            Probably I've found the problem:
            when I create the new module (empty) DNN creates the ascx file with this in header:
            Control Language="Visual Basic" ClassName....

            But the string "Visual Basic" is not valid (I'm VB developer from long time).
            So I changed it to "vb" and....now the error message does not appears any more.

            This is wrong:
            Control Language="Visual Basic" ClassName

            This is correct:
            Control Language="vb" ClassName

            Have a nice day!

              Digging around in some old websites, I found a codedom section in web.config that has a compilers section.

              Also, there is a codeSubDirectories section.

              You may need one or both of these. But, as I said, it's been a long time since I've had to work in that arena. You may want to look for some old "how to build a DotNetNuke module" references using Google. Something before version 7 I think.

              Hopefully, some folks here have longer memories than I do.

                Don't worry! 

                I've solved as written above.
                Thank you very much for your help.
