        Try
            'Dim PathFile As String = "C:\WOMEN_FOUND\database"
            'Create Request
            Dim Request As System.Net.FtpWebRequest = DirectCast(System.Net.WebRequest.Create(Str_Url), System.Net.FtpWebRequest)

            'Upload Properties
            Request.Credentials = New System.Net.NetworkCredential(Str_Username, Str_Pwd)
            Request.Method = System.Net.WebRequestMethods.Ftp.UploadFile

            'Read File
            Dim File() As Byte = System.IO.File.ReadAllBytes(Str_PathBase)

            'Upload
            Dim Strz As System.IO.Stream = Request.GetRequestStream() ' Error ตรงนี้ว่า The requested URI is invalid for this FTP command.
            Strz.Write(File, 0, File.Length)

            Strz.Close()
            Strz.Dispose()

            If System.IO.File.Exists(Str_PathBase) = True Then
                System.IO.File.Delete(Str_PathBase)
            End If

            'MessageBox.Show("Upload Done", "Messsage")
