I am brand spanking new to runtime db connections. I have a simple query problem that I can't seem to input the correct search criteria into Google find help.

Facts:
Using OleDB
runtime dev

Issue: I have a text box I want to use as the condition in which to query my Customer table and produce results in a DataGridView in VB. Everytime I execute my code I get the following: "Syntax error in string in query expression 'LastName >= (textbox contents)"

Here is my small sub executing this query:
Code:
    Public Sub SearchMenu()
        Dim SearchBox As String
        SearchBox = frmMain.txtName.Text
        Connection.Open()
        dvdDataSet.Clear()
        accCommand.CommandText = "SELECT * FROM Customer WHERE LastName >=' " & SearchBox
        accCommand.Connection = Connection
        dvdDataAdapter.SelectCommand = accCommand

        dvdDataAdapter.Fill(dvdDataSet, "Customers")
        frmMain.dvgFrmMain.DataSource = dvdDataSet.Tables("Customers")
    End Sub
Can anyone throw me a bone on this? My Gaddis book is just completely useless on database use.

Thanks a lot.
