Thanks for the quick reply. I looked at the idl, and it seems to be what I need. However, I have no idea how to actually *call* the function from outside of Firefox. I see "[scriptable, uuid(44b3153e-a54e-4077-a527-b0325e40924e)]" but honestly, I'm not sure what that tells me. I'm a straight "C" guy, and recently have been doing .NET develpment.. In other words, I have no idea what I'm looking at here. Can I call it from a DLL? ActiveX? I looked all over Mozilla's site, but no dice. I just need to know how to actually put this to work. C++ is no good, since I'll be ultimately calling this function from VB. Thanks, Mike. _______________________________________________ Mozilla-netlib mailing list [EMAIL PROTECTED] http://mail.mozilla.org/listinfo/mozilla-netlib
