How about the registry?.. All COM components declare their threading model in the registry, so that would be the first place to look. (Well, all well-written ones do.) Find out the class's CLSID, look that up under HKEY_CLASSES_ROOT\CLSID in the registry, and underneath the InprocServer32 key for the component there should be a ThreadingModel value. I'm guessing that this value is Apartment in your case. (Or possibly it is absent.) If that's right, the COM component is single threaded. If the ThreadingModel is absent you're stuffed - all instances of the component will have to run on the same thread. You'll have to stop using the component to get around this problem. (But then why are you using a COM component to make a call into a web service anyway? .NET provides all sorts of native support for this, so you shouldn't need an interop solution!) If it's Apartment, you'll need to make sure that each of your threads intialize COM to use an STA. To do this make this the first thing you do in each newly-launched thread: Thread.CurrentThread.ApartmentState = ApartmentState.STA; See if that fixes the problem. > So, this all being said, I like the idea of sockets, but I don't even > know where to start.

Well .NET has built-in SOAP support, so it should be fairly straightforward. But I would need more information on what the service you are trying to use requires. (I'm not familiar with the library you're using, plus I'm not really a VB guy, so it's difficult to me to infer what it's trying to do.) -- Ian Griffiths DevelopMentor You can read messages from the Advanced DOTNET archive, unsubscribe from Advanced DOTNET, or subscribe to other DevelopMentor lists at http://discuss.develop.com.
