How to Test SSRS Custom Data Extension in TSql

Question

Hi There,
I have created a custom data extenstion for SSRS 2008 Reporting Service.
I can test the CDE in the Report DataSet -> DataSet Properties -> Query Designer -> Run Query.
In the Command Text I pass parameters to the invoked VB code which is of type "BaanstedeCds" then name of my custom data extension.
I can even Attach the Visual Studio VB Code Project that is invoked by the Query Designer an debug the code.
The custom data extension works perfectly in SSRS.
However I have not found a way yet to run BaanstedeCds (with a parametertext) from within SSMS 2008 by using an T-SQL statement!!! Is there a way to use the SSRS Custom Data Extension in Sql Server Management Studio using the dataset type I used in
SSRS 2008?
Because I am leaving the path of using Custom Assemblies in SSMS, for deploying an testing that way is undoable for me.
I is to complicated and in order to properly debug these routines the entire solution of multiple projects is deployed each time even the slightest change has been made to the VB code. Also if I want to deploy from Test to Production it is very hard. I have
to detach the databases etc, ect.  Note my previous question about this subject that remained unanswered!!!
Using the Custom Data Extension the problems are a lot less. However I how do I use a routine in the CDS in T-SQL, like I could invoke a routine in the Custom Code Assemblies?
 I "hate" CLR routines. I have extreme trouble managing these CLR's as I explained in my post and other posts in the past.
You just cannot build a maagable system that way.
I had to convert all the CLR's (I had a lot of them) to Custom Data Extension Functions, as they do not have all the drawbacks  of CLR's.
And using the CDE with all the converted CLR's in it works much better for me in the Report Manager.
However in order to test de CDE I must invoke the CDE in a Windows Form something like this:
Private Sub cmdGetData_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdGetData.Click
Dim CommandText As String = ""
' Get Parameters for CDE GetData
CommandText = txtAdoCds.Text
Dim Rdr As New BstCds.BaanstedeCdsReader(CommandText)
' Invoke GetData Function of CDE Rdr
' Input: CommandText: txtAdoCds.Text = TextBox on TestForm
' Output: DataTable: RdrDataTable
Call Rdr.GetData(CommandText)
If Not Rdr.RdrRetVal Then
GoTo End_Method
End If
' Show DataTable: RdrDataTable (in Excel)
If Not BstOff.ToonTabel(DataTabel:=Rdr.RdrDataTable) Then
Exit Sub
End If
End_Method:
End Sub
'=========================================================================
' File: BaanstedeCdsReader.vb
' Summary: Provides a means of reading one or more forward-only streams
' of result sets obtained by executing a command at a data source,
' and is implemented by Baanstede Data Processing Extensions
' that access BaanstedeIw3-routines.
'=========================================================================
Public Class BaanstedeCdsReader
Implements IDataReader
#Region "Public Variables"
Public RdrRetVal As Boolean = False
Public RdrSqlSel As String = ""
Public RdrDataTable As DataTable = New DataTable
#End Region
#Region "Constructors"
#End Region
#Region "IDataReader Members"
#End Region
' GetData '
#Region "GetData Method"
'==================================================================================================
'We are executing the command using the connection string that connects to the Active Directory.
'Hard coding of the connection string is because it is the same for all the ADs.
'Once we read the data using a DataReader, we place the same in a DataTable so that can be used for
'Other processings.
' Public Sub GetData(ByVal _CommandText As String)
' Output in Public RdrDataTable As DataTable
'==================================================================================================
Public Sub GetData(ByVal _CommandText As String)
' Ophalen Data in DataTabel '
RdrRetVal = False
' Fills RdrDataTable Using _COmmandText
RdrRetVal = True
End Sub
But can I invoke Report Manager Source Type BaanstdeCds's .BaanstedeCdsReader.GetData(CommandText) in TSQL any other way then using CLR ?

It works, but it does not work (The program runs, but does not produce the desired result)

Hi Josje,
Thank you for your question.
I am trying to involve someone more familiar with this topic for a further look at this issue. Sometime delay might be expected from the job transferring. Your patience is greatly appreciated.
Thank you for your understanding and support.
