I would appreciate any assistance with getting my sql select statement to work so that any matches from data in my textbox will result in my dgv being populated with the matches.  Right now I just get a blank dg, even though I know there are matches.
Dim cString As String = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=c:/log1/labeldb.mdb"
        Dim sqlString As String = "SELECT * FROM Log1 WHERE wDD=" & tDate.Text
        Dim OleDBCon As System.Data.OleDb.OleDbConnection = New System.Data.OleDb.OleDbConnection(cString)
        Dim DataSet As New DataSet()
        Dim OleDbDataAdapter1 As System.Data.OleDb.OleDbDataAdapter = New System.Data.OleDb.OleDbDataAdapter(sqlString, OleDBCon)
        OleDBCon.Open()
        OleDbDataAdapter1.Fill(DataSet, "Log1")
        DG1.DataSource = DataSet.Tables("Log1")

Open in new window

Check the date format(?) entered in the tDate text box. Also try the following format...

Dim sqlString As String = "SELECT * FROM Log1 WHERE wDD='" & tDate.Text & "'"

Thanks, yours seems to have more spacing between the single and double quotes than all of the combinations I've been trying for the past hour or so.  I'll let you know in a few minutes after I run it.
