Hi,

  I am using dotnetnuke 4.6 and have installed the source of the documents module by converting it to a VS2005 Web application project using the steps in the following link:

http://dnnla.nesinteractivos.com/DNNLibrary/tabid/88/TID/13/cid/12/Default.aspx

I am able to build the project and add it in my portal. But i want to make a change to the documents module in which the list of uploaded documents show up in the page based on the users who uploaded it. For example if user A uploades document D1 and B uploads D2, A can only see D1 in the list and B can see only D2. I made the change and built the project. I modified the SP getDocuments as well. Everything build fine. But once i refresh the dotnetnuke webpage, i get the following error. Can someone help me out in this regard.

Error: Documents is currently unavailable.
DotNetNuke.Services.Exceptions.ModuleLoadException: The type initializer for 'DotNetNuke.Modules.Documents.DataProvider' threw an exception. ---> System.TypeInitializationException: The type initializer for 'DotNetNuke.Modules.Documents.DataProvider' threw an exception. ---> System.ArgumentNullException: Value cannot be null.

Thanx,

I believe I did the exact same thing you did over the weekend.  I wanted to make some changes to the module, so I thought a good place to start would be to upgrade the documents module to asp.net 2.0.  What resolved my error was a modification to the "dataprovider.vb" file in the "app_code\documents" folder.

Change the following line from:
        Private Shared Sub CreateProvider()
            objProvider = CType(Framework.Reflection.CreateObject("data", "DotNetNuke.Modules.Documents", "DotNetNuke.Modules.Documents"), DataProvider)
        End Sub

to

        Private Shared Sub CreateProvider()
            objProvider = CType(Framework.Reflection.CreateObject("data", "DotNetNuke.Modules.Documents", ""), DataProvider)
        End Sub

I'm not quote sure why that resolved the issue, but I guess the "DotNetNuke.Modules.Documents" assembly need not be referenced with the DataProvider.
