heres a few classes i wrote a while back,
it probably needs a bit of tidying up, but it works
some nice functions for setting the values of an HTML form once the page has
loaded + submitting a button from a windows forms app.
The main one you'll be interested in though is...
public void Navigate(string _url, string _valuedatapairs)..
this method you just call like :
webcontrol.Navigate("www.yahoo.co.uk","param1=one& param2=two&etc=easyasthis"
);
if you want to pass values to an array from a list box, use a for loop, and
make each parameter the same name.... but you probably
know what to do from here.
also started doing some work on showing a custom context menu -
anyway, hope this helps
(you'll need to get VS.NET to create a wrapper for the WebControl) - i
haven't included it here

Exactly what the subject says.
I have an ASP page that I want my C# windows application to open in
Internet Explorer, and if possible have it send along a list of values
from a list box. Thank you.
