How to use Ctime?

[andydang]

I did that, and i used that. this this the code fragment that i use.

void ???::OnTimer(UINT nIDEvent)
{...
 switch (nIDEvent)
  {
  case ID_CLOCK_TIMER
  break;
  case ID_COUNT_TIMER
  //**
  //the only place (that i know of) that executes once every 100ms
  m_iCount++;
  break;
  }
UpdateData(FALSE);
...
}
...
void ???::OnSimulate()
{
//*
m_iCount=0;
SetTimer(ID_COUNT_TIMER, 100, NULL)
}

is there a way where i can circumvent this method? I meant that the only way i can make sure something happens every 100ms is to put my codes at ** instead of at *. Now, for short codes I wouldn't mind, but the bulk(hundreds of lines) of my codes depend upon it executing every 100ms. is there anyway that i could put my codes in * and still it executes every 100ms??
