 // The 'window_title' is the text displayed on the title bar of the dialog. If
 // you pass an empty string the dialog will have a generic 'windows security'
 // name on the title bar.
 //
 // You must provide a valid 'full_path' to the file to be opened and a well
 // formed url in 'source_url'. The url should identify the source of the file
 // but does not have to be network-reachable. If the url is malformed a
 // dialog will be shown telling the user that the file will be blocked.
 //
 // In the event that there is no default application registered for the file
 // specified by 'full_path' it ask the user, via the Windows "Open With"
 // dialog, for an application to use if 'ask_for_app' is true.
 // Returns 'true' on successful open, 'false' otherwise.
