I am trying to use the winsock activeX control from Wincc v5.1 or v6.0. I am having a problem that I am describing below:
The listener enters the listening mode perfectly OK.
The client sends the connection request.
The listener gets it, and it raises the "connectionrequest" event. According to Microsoft, within the context of this event, the method "accept" must be called in the listener. As soon as I call this method I get the OLE error 0x80020003 (member not found!!!).
The client raises the "connect" event, with status 8 (closing).
The client raises the "close" event.
This behaviour is identical in all possible combinations: winCC v 5.1, winCC v 6.0, windows 2k pro, windows 2k server, windows NT4. The winsock control always comes from visual studio 6.0. In case anybody is interested, I can e-mail the wincc project to him.
