This example uploads the file Order.txt to http://www.cohowinery.com/uploads.
My.Computer.Network.UploadFile ( "C:\My Documents\Order.txt",
"http://www.cohowinery.com/upload.aspx")
This example uploads the file Order.txt to http://www.cohowinery.com/uploads without supplying a user name or password, shows the progress of the upload, and has a time-out interval of 500 milliseconds.
My.Computer.Network.UploadFile ("C:\My Documents\Order.txt",
"http://www.cohowinery.com/upload.aspx","","",True,500)
Remarks
If showUI is set to True, a dialog box shows the progress of the operation and includes a Cancel button that the user can click to cancel the operation. Because the dialog box is not modal, it does not block user input to other windows in the program.
If the server does not respond within the interval specified in connectionTimeout, the operation is cancelled and an exception is thrown.
My.Computer.Network.UploadFile outputs trace information when you enable network tracing in your application. For more information, see Enabling Network Tracing.
