Mark,

I ran into this problem doing an interactive voice response system a few years ago. Since vfp is single threaded, it can only respond to one com object at a time. I ended up having to write responses to a dbf file and then have a process scan the dbf on a regular basis and take appropriate action.

>I have a client program that creates two remote servers. Both servers are given a reference to the client for callbacks.

>oClient.Server1 = CREATEOBJECTEX('{...}', 'comp1')
>oClient.Server2 = CREATEOBJECTEX('{...}', 'comp2')
>oClient.Server1.mGetClient(oClient)
>oClient.Server2.mGetClient(oClient)
>
>*!* Callback from the server1
>oClient.mCallBack()
>
>*!* Callback from the server2
>oClient.mCallBack()
>
>What would happen when both servers do the callback in the same time?
>Am I at any danger of it?
