   And (File1.PostedFile.ContentLength > 0) Then
   ''determine file name
   Dim sFileName As String = _
      System.IO.Path.GetFileName(File1.PostedFile.FileName)
   Try
      If File1.PostedFile.ContentLength <= lMaxFileSize Then
         ''save file on disk
         File1.PostedFile.SaveAs(sFileDir + sFileName)
         lblMessage.Visible = True
         lblMessage.Text = "File: " + sFileDir + sFileName + _
            " Uploaded Successfully"
      Else    ''reject file
         lblMessage.Visible = True
         lblMessage.Text = "File Size if Over the Limit of " + _
            lMaxFileSize
      End If
   Catch exc As Exception    ''in case of an error
      lblMessage.Visible = True
      lblMessage.Text = "An Error Occured. Please Try Again!"
      DeleteFile(sFileDir + sFileName)
   End Try
Else
   lblMessage.Visible = True
   lblMessage.Text = "Nothing to upload. Please Try Again!"
End If
