Hi all,

I'm trying create dynamic reports by Crystal Reports engine distributed with
VS.NET. I know there is only lite version without native support to do this,
but I've found another way via using CRAXDDRT20 library (Crystal Reports
..NET ActiveX Designer Design and Runtime library).

But I've problem with adding table by passing ADO recordset:

loCRGenerator = new CRAXDDRT20.ApplicationClass();
loReport = loCRGenerator.NewReport();

ADODB.RecordsetClass loADO = new ADODB.RecordsetClass();

foreach (DataColumn loColumn in aoDataGrid.CurrentDataTable.Columns)
{
loADO.Fields.Append(loColumn.ColumnName, ADODB.DataTypeEnum.adVarChar,
50, ADODB.FieldAttributeEnum.adFldMayBeNull);
}

loADO.Open(Missing.Value, Missing.Value, ADODB.CursorTypeEnum.adOpenDynamic,
ADODB.LockTypeEnum.adLockBatchOptimistic, 0);
loReport.Database.Tables.Add("", Type.Missing, loADO, Type.Missing,
"p2smon.dll", Type.Missing, Type.Missing, Type.Missing, Type.Missing,
Type.Missing); <-- here raises error :-(

Error message says: "Type mismatch" ...

Please can You help me? Or exist another way how to do this there?

Thanks
