    Private Function FTPCheck(ByVal uri As String, ByVal user As String, ByVal pass As String, ByRef errmsg As String) As Boolean
        Try
            Dim req As Net.FtpWebRequest = Net.FtpWebRequest.Create(uri)
            req.Credentials = New Net.NetworkCredential(user, pass)
            req.Method = Net.WebRequestMethods.Ftp.PrintWorkingDirectory
            Dim response As Net.FtpWebResponse = req.GetResponse()
            Return True
        Catch ex As Exception
            errmsg = ex.Message
            Return False
        End Try
    End Function

        Dim errmsg As String = ""
        If FTPCheck("ftp://ftp.microsoft.com", "anonymous", "blub", errmsg) Then
            MessageBox.Show("check ok")
