Using C++/CLI, I have an instance function which I intend to be the entry point for a thread... I start it up like so...


Threading::ThreadStart^ ts = gcnew Threading::ThreadStart(this,
   &MyClass::TheThreadFunc);

Threading::Thread^ t = gcnew Threading::Thread(ts);
t->Start();

That seems to work, sort of. The thread starts running, but I get a NullReferenceException inside of the thread worker function when it tries to access an member object reference. Is there something I am doing wrong that could cause this? I've never played with C++/CLI extensively before.

There's a ton of different things that can cause this, and not enough info provided to tell which it is. Maybe post more code?

Are you certain that you didn't just forget to assign something to the member?

Actually, I didn't change a thing--to my recollection--and it works today. I don't get it.

If it exhibits that behavior again I'll check back in. For now, I'm going to assume I changed something that I can't remember.
