Unless you learn about it yourself, you probably do not want to hand in a solution that uses it.

int upper = 0;
int alpha = 0;
int digit = 0;

...
if (isupper(pwd[x])) // this does not check for special characters
    upper = 1;
else if (isalpha(pwd[x]))
    alpha = 1;
else if (isdigit(pwd[x]))

...

My worker thread is passing message to the mainframe window with PostMessage.

That thread does not call PostMessage a lot, maybe 4, 5 times in all when it is used.

What would be the best way to track down unruly messages that fills the message queue ?

void f(CWnd* p) // p is a pointer to the mainframe
{ 
  p->PostMessage(MESSAGEID, 0, 0 );

  const DWORD dwEvent = WaitForMultipleObjects(NB_EVENT_REGISTERED, ghEventList, FALSE, INFINITE);
  // .... 
}

ON_MESSAGE(MESSAGEID, OnMESSAGEID )
//....

LRESULT CMainFrame::OnMESSAGEID (WPARAM wParam, LPARAM  lParam)
{
  //... do stuff.
  SetEvent(ghEventList[0]);
