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", "")

Destination is unclear

I don't think this instruction is clear about the destination of the uploading.

It seems it has to be a file, but what type of file? must it be an aspx file? if so, any code required in the aspx?

And will the source file be uploaded into the folder where the aspx file is? it's not clear.

Would be helpful if there is a detailed example .

I Agree, Destination is unclear
I agree, this needs to be more descriptive and not rely on user knowledge. Please be more descriptive.

Just like uploading from a form
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:

Or look at this video showing you how to make a simple fileupload page:

Nothing is Clear.
The UploadFile method has 10 variants and the progressbar is supported in one type only. Please clear it.
