I'm using the managed WebBrowser control that comes with .Net 2.0 to open office documents like Word and Excel. But before openning the document, it displays an annying warning and asks to the user whether he wants to open/save the document or cancel. I want to disable this message and open the document immediately because this is a document management application and it is safe to open all the documents. My application should not change any of the options in users registry and disabling this warning should be restricted to my browser control in the application. Other explorer windows should not be affected.
