If you're using the default WebBrowser control and would like to clear your Cookies, History, Forms Data etc then the following can do this. If using a button/menu item to perform this then just add one of the following into the button or menu item's click event.
Code:
'Temporary Internet Files
System.Diagnostics.Process.Start("rundll32.exe", "InetCpl.cpl,ClearMyTracksByProcess 8")
'Cookies()
System.Diagnostics.Process.Start("rundll32.exe", "InetCpl.cpl,ClearMyTracksByProcess 2")
'History()
System.Diagnostics.Process.Start("rundll32.exe", "InetCpl.cpl,ClearMyTracksByProcess 1")
'Form(Data)
System.Diagnostics.Process.Start("rundll32.exe", "InetCpl.cpl,ClearMyTracksByProcess 16")
'Passwords()
System.Diagnostics.Process.Start("rundll32.exe", "InetCpl.cpl,ClearMyTracksByProcess 32")
'Delete(All)
System.Diagnostics.Process.Start("rundll32.exe", "InetCpl.cpl,ClearMyTracksByProcess 255")
'Delete All – Also delete files and settings stored by add-ons
System.Diagnostics.Process.Start("rundll32.exe", "InetCpl.cpl,ClearMyTracksByProcess 4351")
