Hello,
I am trying to use the TabController API to create a series of pages automatically from another windows application. I am however, running into problems when I try and use the following line of code:

DataProvider provider = DotNetNuke.Data.DataProvider.Instance();

I get the exception :

System.TypeInitializationException was unhandled
  Message="The type initializer for 'DotNetNuke.Data.DataProvider' threw an exception."
  Source="DotNetNuke"
  TypeName="DotNetNuke.Data.DataProvider"
  StackTrace:

I expect this is to do with Reflection and inability for it to create the SqlDataProvider concrete class, but I do now know how to tell DNN which data provider to use. I have guessed that the app.config file is the place to do it in the section called: <data> which I have attempted to mimic in the windows's app.config by copying most of the web.config into it.

<data defaultProvider="SqlDataProvider">

<providers>

<clear/>

<add name="SqlDataProvider" type="DotNetNuke.Data.SqlDataProvider, DotNetNuke.SqlDataProvider" connectionStringName="SiteSqlServer" upgradeConnectionString="" providerPath="c:\code\dnn\Providers\DataProviders\SqlDataProvider\" objectQualifier="" databaseOwner="dbo"/>

</providers>

</data>

Does anyone have any suggestions, or I am unable to do what I am trying to do?

Thanks Nik,

This is my entire app.config file as I have it now, I started off, with the entire web.config file placed into my app.config file. But not I have cut it back to (see end of post) .

Are there other examples out there on how to call the API from NON-WEB project?

Regards, Chris.

The code I am executing is:

public VEMS_DNN_Synchroniser()

mController = new TabController();

DataProvider provider = DotNetNuke.Data.DataProvider.Instance();

mHome = mController.GetTabByName("Home", mPortalID);

The exception I get is :

System.TypeInitializationException was unhandled
  Message="The type initializer for 'DotNetNuke.Data.DataProvider' threw an exception."
  Source="DotNetNuke"
  TypeName="DotNetNuke.Data.DataProvider"
