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 download and allows users to cancel the operation.

To upload a file

  • Use the UploadFile method to upload a file, specifying the source file's location and the target directory location as a string or URI (Uniform Resource Identifier).This example uploads the file Order.txt to http://www.cohowinery.com/uploads.aspx.

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

    My.Computer.Network.UploadFile(
      "C:\My Documents\Order.txt",
      "http://www.cohowinery.com/upload.aspx", "", "", True, 500)
