This video [this video] should give you all of the information that you need. It is a tutorial on creating an automatic yahoo login from vb, but it will show you how to pass values to a textbox on a webpage, as well as working with other webpage controls. NOTE: You will need to navigate to the page and view source to get the id of the controls
