How to emulate user clicks in WebBrowser or Gecko WPF

I need emulate some user activity on website with some scrolling, mouse click and keyboard types. The pr开发者_运维技巧oblem is I can't find solution to make mouse clicks and mouse moving in default WebBrowser component. Do you know alternative solutions?

Thanks and sorry for my bad English.

One possible option would be to use a client testing tool, like White, to automate the UI. This may not be the most elegant solution, but it will let you emulate the clicks you need.
