Re: Presentation Page error 80040500

Good news, thank you.

After the last my post, I found such sentence in UPnP DA document;
"Any in arguments must be listed before any out arguments."

So,  the problem was not a Microsoft WinXP+IE6 bug.
The problem was simply a typo of tvsample service descriptons.
Sorry Microsoft :-)

Yasuhiro Morioka
