How to: Upload a File in Visual Basic

The UploadFile method can be used to upload a file and store it to a remote location. If the ShowUI parameter is set to True, a dialog box is displayed that shows the progress of the upload and allows users to cancel the operation.

      "C:\My Documents\Order.txt",
      "http://www.cohowinery.com/upload.aspx")
