However, a global variable would not work because two threads might be inside the recursive call simultaneously. But a thread-local variable would work. (If you...
In the discussion following my entry about dialog procedure return values, somebody suggested an alternate dialog design where you just call to do default actions (the same way you write window procedures and ) rather than returning TRUE/FALSE. So let's do that. In fact, we're going to do it twice. I'll cover one method today and cover an ...
