麻烦各位给我看看下面这段代码！

[magerate]

Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click
Dim strAccConn As String = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=..\data.mdb"
Dim objConn As New OleDbConnection(strAccConn)
Dim objComm As New OleDbCommand("delete from myfriend where name=magerate", objConn)
Try
objConn.Open()
objComm.ExecuteNonQuery()
Catch myException As Exception
MessageBox.Show(myException.ToString())
End Try
End Sub
返回的错误如下：
System.Data.OleDb.OleDbException: 至少一个参数没有被指定值。

try

Dim objComm As New OleDbCommand("delete from myfriend where [name]='magerate'", objConn)
