i have a program which automates the filling in of a form, i used setattribute and invokemember("onchange") and invokemember("click") for this, and i also need a way to upload a file automatically,

the website contains a button.
when it is clicked, a flebrowserdialog opens and i have to manually select the file to upload

using the standard browsercontrol there is apparently no way to bypass the openfilebrowser window to upload the file,
i need some browsercomponent which allows me to upload the file without me having to manually search the file in the filebrowserdialog

does annyone know of a browsercomponent for .net which allows you to upload files and still allows to trigger onchange and click events??
