Hi, I'm having a problem filling in forms which have an file input type (a file browser/upload field). Here is a sample of the HTML that I'm trying manipulate:

<input type="file" id="toupload" name="toupload" size="30" />

I've been able to fill in the values of text fields and other things just fine by using something like this:

WebBrowser1.Document.All.Item("firstname").SetAttribute("value", FirstName)

However, it obviously doesn't work for file inputs because they don't have a value to change. Does anyone know how I can do this?
