I'd like to use the DMX API outside the context of DNN to provide Entry Info data to another system.  I've been trying to get an instance of the SqlDataProvider using the following code:

Bring2mind.DNN.Modules.DMX.Data.

DataProvider dmxDataProvider = (Bring2mind.DNN.Modules.DMX.Data.DataProvider)DotNetNuke.Framework.Reflection.CreateObject("dmxdata");

with the following configuration:

dmxdata defaultProvider="dmxSqlDataProvider">providers>clear />add name="dmxSqlDataProvider" type="Bring2mind.DNN.Modules.DMX.Data.SqlDataProvider, Bring2mind.DNN.Modules.DMX.Core" connectionString="SiteSqlServer" upgradeConnectionString="" providerPath="" objectQualifier="" databaseOwner="dbo" />providers>dmxdata>

dotnetnuke>

but get the following exception:

System.ArgumentNullException : Value cannot be null.
Parameter name: type
   at System.Activator.CreateInstance(Type type, Boolean nonPublic)
   at System.Activator.CreateInstance(Type type)
   at DotNetNuke.Framework.Reflection.CreateObject(String TypeName, String CacheKey, Boolean UseCache)
   at DotNetNuke.Framework.Reflection.CreateObject(String ObjectProviderType, String ObjectProviderName, String ObjectNamespace, String ObjectAssemblyName, Boolean UseCache)
   at DotNetNuke.Framework.Reflection.CreateObject(String ObjectProviderType, String ObjectNamespace, String ObjectAssemblyName)...

What needs to be done in order to get the DMX data provider instance when executing outside of DNN?

Looks like the forum tool completely munged the config section, but you get the idea...

But creating a SqlDataProvider is where the problem occurrs.  The following throws an exception within its constructor:

Bring2mind.DNN.Modules.DMX.Data.

SqlDataProvider dataprovider = new Bring2mind.DNN.Modules.DMX.Data.SqlDataProvider();
