[PD-dev] using CSocket in external

Hello!

I'm trying to use a MFC CSocket in an pd external written with flext. I am able to connect and send messages to to my corresponding application. This application receives the message and responses to it. This response leaves the application (checked with a sniffer) and should be received by my external. The problem is, that CAsyncSocket::OnReceive is not called.

The thing is, that the same messaging/socket system is working when i use it in an other application, but not withing my pd-external.

So, has someone experiences with a CSocket in an external, or some ideas why OnReceive is not called, or some other hints?

Thanks a lot in advance,
