I have the following code in vb.net.  I do not get an error and if I copy mstr to access query it does return results, but from vb.net it returns 0 records.  Any Ideas.

thanks


Private Sub btnSearch_Click(sender As Object, e As EventArgs) Handles btnSearch.Click
        Dim mycriteria As String = BuildSearchCriteria()
        Dim dsSearch As New DataSet
        Dim daSearch As New OleDbDataAdapter
        Dim cmdSearch As New OleDbCommand
        Dim myConn As New OleDbConnection(mConn)
        Dim mStr As String = String.Empty
        mStr = "select a.propertyid ,a.bldgid,a.unitid, a.resiid,a.occufirstname, a.occulastname,b.FullID as ResidentFullID, "
        mStr = mStr & "b.Status,b.id,a.ResponsibleFlag, b.ListedDate,rtrim(a.OccuLastName)+', '+ RTRIM(a.OccuFirstName) as resiName, "
        mStr = mStr & "b.TotalAmt,b.OriginalAmt,b.CFeeAmt,b.CBY_AcctNo,   '' as resistatus from Occupants a left outer join Master b on "
        mStr = mStr & "a.PropertyId=b.PropertyID and a.BldgId=b.BldgID and a.UnitId=b.UnitID and a.ResiId=b.ResiID "
        mStr = mStr & mycriteria
        With cmdSearch
            .Connection = myConn
            .CommandText = mStr
            .CommandType = CommandType.Text
        End With
        daSearch.SelectCommand = cmdSearch
        daSearch.Fill(dsSearch)
        dgSearch.DataSource = dsSearch.Tables(0)



    End Sub

below is the strings.  Again if I copy mstr to access it works.


myCriteria

Where a.occufirstname like 'jo*' and a.occulastname like 'davis*' "

mystr with mycriteria

"select a.propertyid ,a.bldgid,a.unitid, a.resiid,a.occufirstname, a.occulastname,b.FullID as ResidentFullID, b.Status,b.id,a.ResponsibleFlag, b.ListedDate,rtrim(a.OccuLastName)+', '+ RTRIM(a.OccuFirstName) as resiName, b.TotalAmt,b.OriginalAmt,b.CFeeAmt,b.CBY_AcctNo,   '' as resistatus from Occupants a left outer join Master b on a.PropertyId=b.PropertyID and a.BldgId=b.BldgID and a.UnitId=b.UnitID and a.ResiId=b.ResiID Where a.occufirstname like 'jo*' and a.occulastname like 'davis*' "

Sorry that didn't do the trick Gustav.   Here is what it looks like now.  Again it works in access query.

 
select a.propertyid ,a.bldgid,a.unitid, a.resiid,a.occufirstname, a.occulastname,b.FullID as ResidentFullID, b.Status,b.id,a.ResponsibleFlag, b.ListedDate,rtrim(a.OccuLastName)+', '+ RTRIM(a.OccuFirstName) as resiName, b.TotalAmt,b.OriginalAmt,b.CFeeAmt,b.CBY_AcctNo,'' as resistatus from Occupants as a left outer join Master b on a.PropertyId=b.PropertyID and a.BldgId=b.BldgID and a.UnitId=b.UnitID and a.ResiId=b.ResiID Where a.occufirstname like 'jo*' and a.occulastname like 'davis*'

As it turns out they want you to use the % when you're using it from Vbnet so if I change the Asterick to a % then it works. thanks for your help
