Caution ADO and ADO MD have not been fully tested in a Microsoft .NET Framework environment. They may cause intermittent issues, especially in service-based applications or in multithreaded applications. The techniques that are discussed in this article should only be used as a temporary measure during migration to ADO.NET. You should only use these techniques after you have conducted complete testing to make sure that there are no compatibility issues. Any issues that are caused by using ADO or ADO MD in this manner are unsupported. For more information, see the following article in the Microsoft Knowledge Base:

840667 You receive unexpected errors when using ADO and ADO MD in a .NET Framework application



SYMPTOMS
The Fill method of the DataAdapter object of the OLE DB managed provider may not work correctly when you apply an ADO Recordset object with filter criteria, and you use the Recordset object to populate the Dataset object.

You set the criteria for the Recordset object. When you open the Recordset object by using the filter criteria, and you try to fill the records in the Dataset object by using the Fill method of the OleDbDataAdapter object, the action fails, and you receive the following exception error message:

An unhandled exception of type 'System.Reflection.TargetInvocationException' occurred in system.data.dll

Additional information: Exception has been thrown by the target of an invocation.

Steps to reproduce the behavior
 Start Microsoft Visual Studio .NET 2003. On the File menu, point to New, and then click Project. Under Project Types, click Visual Basic Projects, and then click Windows Application under Templates. Name the project.

Note is a placeholder for the name of the application. Add a Button control to Form1.</li> Add a reference to adodb. To add this reference, follow these steps: <ol style="list-style-type: lower-alpha;"> In Solution Explorer, right-click References.</li> Click Add Reference.</li> On the .NET tab, click adodb, and then click Select.</li> Click OK.</li></ol> </li>  Add the following code at the top of the code window: Imports System.Data.OleDb </li>  In the click event of the Button1 control, add the following code: Dim ADOCn As New ADODB.Connection Dim ADORs As New ADODB.Recordset 'Connect Database Server

ADOCn.Open(&quot;Provider=SQLOLEDB;Data Source=servername;Initial Catalog=Northwind;Integrated Security=SSPI&quot;) 'Do a simple filter criteria ADORs.Filter = &quot;CustomerID = 'ALFKI'&quot; 'Open the Recordset object ADORs.Open(&quot;Customers&quot;, ADOCn) 'Create a new OLEDBDataAdapter object Dim ADOAdapter As New OleDbDataAdapter Dim ADODs As New DataSet 'Use the Fill Method ADOAdapter.Fill(ADODs, ADORs, &quot;emp&quot;) ADOAdapter.Dispose ADOAdapter = Nothing ADOCn.Close ADOCn = Nothing ADODs.Clear ADODs.Dispose ADODs = Nothing </li> To save the project and the files that are associated with the project, click Save All on the File menu. The project is saved with the name that you originally used in step 4.</li> To build the solution, click Build Solution on the Build menu.</li> To test this code, press F5.
