Easy Newb Q: INSERT into Access

[chakotha]

I am just getting VB.NET and Access talking for the first time and I cannot get this INSERT SQL code to work:

    Public Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnAdd.Click

        Dim strDSN As String = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source = c:\temp\PayeRoll.mdb"

        Dim strSQL As String = "INSERT INTO Companies(CompanyName) VALUES('" & txtNewCompany & "')"

        ' create Objects of ADOConnection and ADOCommand 
        Dim myConnectionString As New OleDbConnection(strDSN) '
        Dim myQuery As New OleDbCommand(strSQL, myConnectionString)

        Try
            myConnectionString.Open()
            myQuery.ExecuteNonQuery()
        Catch myError As Exception
            MsgBox("Uh oh! Something wrong!")
        Finally
            myConnectionString.Close()
            ClearCompanies()
            GetCompanies()
        End Try

    End Sub 

This is causing build error

C:\MyPrograms\ConnectAccess\Form1.vb(153): Operator '&' is not defined for types 'String' and 'System.Windows.Forms.TextBox'.

I have a text entry in Form1 called txtNewCompany and if I try

Dim strSQL As String = "INSERT INTO Companies(CompanyName) VALUES('txtNewCompany')" 

the actual string 'txtNewCompany'goes into ther table, not the value

Any help much appreciated
