Timer dosen't work

Hi!

This timer doesn't work. Coudle anyone please point out why?

Code:

---

//[MFC dialog based app]
....
//we're online! so setup the timer
if(!m_bonline){//call only once after going online
    m_nTimer=SetTimer(1,1000,0);
    if(!m_nTimer)
      AfxMessageBox("SetTimer falied");
}
m_bonline=TRUE;
....
....
void CDialuptimetickerDlg::OnTimer(UINT nIDEvent)
{
  Beep(2000,1000);
  CDialog::OnTimer(nIDEvent);
}
....

---

SetTimer() is called, m_nTimer gets 1, but i can't hear the Beep() inside OnTimer.

thx 4 any help.

I'm just going to assume you just pushed the button twice?

Where does it fail? (use break points to pause the code at a particular line, F9 in MSVC)

Does the OnTimer handler get called?

What does Beep() return?

Have you tried using Beep() elsewhere?

When you get the error what does GetLastError() return?

Seems not. tried a brakepoint inside OnTimer(), but it never gets hit.

yeah it works elsewhere.

returns no error 0, when called after SetTimer(). SetTimer returns a timer identifier (1), but OnTimer is not executed?

Is your app very busy? WM_TIMER msgs are very low priority in the msg queue and can be ignored.

It is the same dlg creating the timer as processing the timer msgs?



Other than that looks good.

Try....

if(!m_bonline && !m_nTimer)


and using a diff ID number

ie
#define ID_TIMER 40001

m_nTimer=SetTimer(ID_TIMER,1000,NULL);

//in OnTimer

if(nIDEvent==m_nTimer)

did all that. but nothing!

no.. i'm only doing a 1 ps loop to check if the user hangs up.

yes. (CDialuptimetickerDlg)

:confused:

Dialuptimeticker

I don't know MFC, but is it possible to get in CDialuptimetickerDlg's wnd proc? That way you could manualy check for WM_TIMER?

gosh it's the while loop!:eek: i have to call the SetTimer from outside the evil while loop.

edit: no wait.. it seems that i have to remove the loop altogether:eek:
