First what is DUMMY? is it a CDialog?

void DUMMY::OnResume()
{
// TODO: Add your control notification handler code here
CWorkerDlg dlg; << Primary window which launched Dummy dialog Window

Why are you creating an object of this class here? Are you trying to access
a dialog that is already created?

dlg.paused = FALSE; << paused defined in CWorkerDlg as BOOL

// sets the state of the specified event object to signaled.
if ( ! ::SetEvent(dlg.hEvnt) )
{
AfxMessageBox("SetEvent not sucessful");
}

Is dlg.hEvnt being created in CWorkerDlg's constructor? because I don't see
anyone creating the event?

// User is done reading the message-Close the window
EndDialog(0);

}

First problem, my SetEvent always reports failure. Why? Also, I get
debug asseration failure windows. When it reaches the last line,
EndDialog(0) it pops up Debug Assertion Failure window. What am I
doing wrong? Thanks for help.

What does the assert say? Where does it take you when you press Retry? The
only assert in EndDialog is ASSERT(::IsWindow(m_hWnd)); which if that is
getting hit means that you are calling EndDialog on a dialog that doesn't
exists. If that was the case I wonder how your OnResume is getting called?
