Are you having trouble using settimer () for an MFC application
I have set this code so that I have a timer to play with the minesweeper, but I cannot compile it.
void CALLBACK CMineSweeperBoard::clock(HWND hwnd, UINT uMsg, UINT timerId, DWORD dwTime)
{
if (t_seconds < 59){ t_seconds++; }
else{
t_minutes++;
t_seconds = 0;
}
}
void CMineSweeperBoard::timer(void)
{
MSG msg;
SetTimer(NULL, 0, 1000, (TIMERPROC) &clock);
while (GetMessage(&msg, NULL, 0, 0)) {
TranslateMessage(&msg);
DispatchMessage(&msg);
}
The problem seems to be related to the arguments in the set timer function, but I can't figure out what that is, any help would be appreciated.

You need SetTimer
, KillTimer
and ON_WM_TIMER()
. See the example at the bottom of this page:
https://msdn.microsoft.com/en-us/library/49313fdf.aspx
Don't put a message loop there While(GetMessage()...)
You can start a 1 second timer by calling SetTimer(1, 1000, NULL);
Then add ON_WM_TIMER()
to the message map that passes the result to void CMyWnd::OnTimer(UINT nIDEvent)
This way you don't need to define your own TimerProc
Or you can provide your own TimerProc, but the TimerProc function must be declared as . This can be inconvenient because static member functions cannot access the item's data. It would be easier to use . static
WM_TIMER
