I'm trying to use XPTC_InvokeByIndex(). At the point where I want to do
this call, all I have is an unknown interface cast as nsISupports, a string
containing the name of the interface, and a string containing the method I
want to call. I was hoping to use nsIInterfaceInfoManager and
GetInfoForName() with the interface name to get the nsInterfaceInfo and
then use GetMethodInfoForName() with the method name to get the index.
However, the nsIInterfaceInfo always shows that nsIDOMDocument only has
three methods (QueryInterface, AddRef, and Release). Does anyone know why
this interface works this way yet other interfaces such as nsIInputStream
work fine?
Thanks for any help,
Bill Phillips
