Hi mdwyer,

this is from MS Develop Support

Private Sub Command1_Click()
Dim cn As New ADODB.Connection
Dim rs As New ADODB.Recordset
Dim cmd As New ADODB.Command
Dim pm As ADODB.Parameter

cn.Open "Provider=SQLOLEDB;Data Source=....."
Set cmd.ActiveConnection = cn
cmd.CommandText = "insert into [description] values(?)"
cmd.CommandType = adCmdText

Set pm = cmd.CreateParameter("@value", adBSTR, adParamInput, 50)
pm.Value = Null

cmd.Parameters.Append pm
cmd.Execute
cn.Close

End Sub
