Catching exceptions from threads

In my multi-threaded application, a Win32 structured exception is
occasionally thrown from a worker thread. Or perhaps a worker thread might throw a C++ exception. I can catch the Win32 structured exception in my
Main thread and take remedial action. However the C++ exception appears to be handle by something (the CRT ?) which (a) pops up an unwanted dialog box and (b) terminates my thread without my main thread ever getting to hear
about it.

I assume the CRT (or whatever) is deciding that I have an unhandled C++
exception and is "helping me out". Can I persuade the CRT somehow that I
want my main thread to catch a C++ exception which has been thrown in a
worker thread?

Obviously I can wrap each worker thread in a C++ try/catch block, but I'd
rather a more generic solution if one is available.

Many thanks

When you get the msg box it probably has Break/Retry/Abort? Break and find
the cause
