Using wildcard to query Access DB in ASP.NET(VB)

I am binding a datagrid to an MS Access DB table. It works fine except when I use a query that involves a wildcard search. I've tried several methods, none of which seem to work. I've even tried the same query within access and it works, but not in .NET.
Here's my query...

select TargetCompany, ID, NextActionDate, NextAction from tblMain where TCProducts like '*" & strKey & "*' or PCType like '*" & strKey & "*' or PCNotes like '*" & strKey & "*' or NextAction like '*" & strKey & "*' or Notes like '*" & strKey & "*' ORDER BY TargetCompany


Like I said, I've tried moving the quotes/asterisks around every way imaginable, and I've tried using = instead of like. I don't get any errors, just not data. Can someone please show me the proper format for writing a query using a wildcard character when connected to an Access DB table through and ASP.NET page (VB)

Here's my vb code also...

    Sub BindData()

Dim strKey As String = Label8.Text
Label1.Text = "select TargetCompany, ID, NextActionDate, NextAction from tblMain where TCProducts like '*" & strKey & "*' or PCType like '*" & strKey & "*' or PCNotes like '*" & strKey & "*' or NextAction like '*" & strKey & "*' or Notes like '*" & strKey & "*' ORDER BY TargetCompany"

    Dim ds As New Data.DataSet
        Dim ConString As String = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source= " & Server.MapPath("contacts.mdb")
        Dim da As New Data.OleDb.OleDbDataAdapter(Label1.Text, ConString)
        da.Fill(ds, "employees")
        GridView1.DataSource = ds.Tables("employees")
        GridView1.DataBind()
    End Sub
