How to: Upload a File in Visual Basic

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

To upload a file and show the progress of the operation

Use the UploadFile method to upload a file, specifying the source file's location and the target directory location as a string or URI. This example uploads the file Order.txt to http://www.cohowinery.com/uploads.aspx without supplying a user name or password, shows the progress of the upload, and has a time-out interval of 500 milliseconds.
Visual Basic
```
My.Computer.Network.UploadFile( _
"C:\My Documents\Order.txt", _
"http://www.cohowinery.com/upload.aspx", "", "", True, 500)
```

To upload a file, supplying a user name and password

Use the UploadFile method to upload a file, specifying the source file's location and the target directory location as a string or URI, and specifying the user name and the password. This example uploads the file Order.txt to http://www.cohowinery.com/uploads.aspx, supplying the user name anonymous and a blank password.
Visual Basic
```
My.Computer.Network.UploadFile( _
"C:\My Documents\Order.txt", _
"http://www.cohowinery.com/upload.aspx", "anonymous", "")
```

The following conditions may throw an exception:

The local file path is not valid (ArgumentException).
Authentication failed (SecurityException).
The connection timed out (TimeoutException).

Maybe not a full description is needed, but at least a reference to the ASP part would be nice. Of course it would depend on the servertype.

Here's a link for those who got Sun Microsystem's ChiliSoft installed on their server:

The UploadFile method has 10 variants and the progressbar is supported in one type only. Please clear it.
