Populating disconnected ADODB.Recordset with System.Data.Dat aTable data.

I need to support a VB6 application that will be receiving
disconnected ADODB.Recordset from out DotNet solution. Our dotnet
solution deals with System.Data.Dat aTable. I need to populate a
disconnected ADODB.Recordset from System.Data.Dat aTable data. Below
is the source code I am implementing to test the process. I do not
get any error, that I can see. The problem I have is that at the end,
the recordset seems to be empty. Any suggestions are very much
appreciated. At this moment I do not know what to do.
Thank you so much for the time and effort you may spend on this
private bool testConvertDT_R S()
System.Data.Dat aTable dt;
ADODB.Recordset rs;

// create dummy data table.
dt = PopulateDataTab le( );

// attempt to populate disconnected ADODB.Recordset
with System.Data.Dat aTable data
rs = ConvertToRS ( dt );

if( null == rs )
throw new Exception(" Recordset is null.");

if( 0 == rs.Fields.Count )
throw new Exception(" Recordset Field count is zero.");

return true;
private System.Data.Dat aTable PopulateDataTab le()

System.Data.Dat aTable dt = new System.Data.Dat aTable();
System.Data.Dat aRow dr;
string[,] ColValues = {{"R1-C1", "R2-C1", "R3-C1", "R4-C1", "R5-C1"}
, {"R1-C2", "R2-C2", "R3-C2", "R4-C2", "R5-C2"} ,
{"R1-C3", "R2-C3", "R3-C3", "R4-C3", "R5-C3"}};

dt.Columns.Add( new System.Data.Dat aColumn("Column 01",
System.Type.Get Type("System.St ring")));
dt.Columns.Add( new System.Data.Dat aColumn("Column 02",
System.Type.Get Type("System.St ring")));
dt.Columns.Add( new System.Data.Dat aColumn("Column 03",
System.Type.Get Type("System.St ring")));
for( int i = 0 ; i < 5 ; i++ )
dr = dt.NewRow();
for( int n = 0 ; n < 3 ; n++ )
dr[n] = ColValues[ n, i];
dt.Rows.Add(dr) ;
return dt;
private ADODB.Recordset ConvertToRS(Sys tem.Data.DataTa ble dt)
ADODB.Recordset rs = new ADODB.Recordset ();


rs.CursorLocati on = ADODB.CursorLoc ationEnum.adUse Client;
rs.ActiveConnec tion = null;

for( int i = 0; i < dt.Columns.Coun t; i++)
rs.Fields.Appen d( dt.Columns[i].ColumnName,
ADODB.DataTypeE num.adBSTR,
ADODB.FieldAttr ibuteEnum.adFld Unspecified,
null );
rs.Open( Type.Missing,
ADODB.CursorTyp eEnum.adOpenSta tic,
ADODB.LockTypeE num.adLockOptim istic,
foreach(System. Data.DataRow dr in dt.Rows)
rs.AddNew(Type. Missing, Type.Missing);

for( int n = 0; n < dt.Columns.Coun t; n++)
rs.Fields[n].Value = dr[n];

rs.Update(Type. Missing, Type.Missing);


return rs;

catch(Exception e)
throw e;

I have a combo box where users select the customer name and can either go to the customer's info or open a list of the customer's orders. The RowSource for the combo box was a simple pass-through query: SELECT DISTINCT , , ,City, Region FROM Customers ORDER BY Customers.; This was working fine until a couple of weeks ago. Now whenever someone has the form open, this statement locks the entire Customers table.
