Sending Values to an ASP

I am working for a company that is using an ASP for uploads, I am writing a mass-upload VB Program so I don't have to upload all 500 images one at a time. With the nature of the asp they are using I need to send values to two fields in the asp and then use the javascript Submit_Form() to submit the page.

I do not have permissions to change the asp code to integrate my program. I have everything written with the exception of the physical connection between the VB program and the Current Browser Window.

I have tried using INet and WindowBrowser. I have also tried just sending a URL string with all the values to the asp script.
