SetTimer(NULL,10000,NULL);

Handle WM_TIMER in your Application

e.g.
void CTestDialogDlg::OnTimer(UINT nIDEvent)
{
AfxMessageBox("I m here") ;
CDialog::OnTimer(nIDEvent);
}

it Should work for You.

I thought pipes could be used for that.

Look at this (it is not specifically for MFC).

However if you do not need a high precision timer (like multimedia ones), you can use SetTimer of CWnd and handle the event fired overriding the OnTimer virtual function (or handle the WM_TIMER explicitly).

Although many people do suggest using the CTimer class See Here)[^]
The SetTimer function and related message and functions are not intended to be precise. Certainly you need to at least use more precise timers. Note that, except for special versions of Windows, Windows is not designed for real-time processing. Don't expect an application program to be able to respond reliably to timer events.
I would suggest you to read this[^] before you implement anything

Well, for a ten seconds timer, I suppose real-time system timing precision is not required.

BTW and IMO it was not a bad piece of information (to be voted down to 1), Sometimes you really need accurate timers and many a times you may not. Things look weird when you come to know that your timer is not getting fired every ten seconds and you want it to behave like that and that too after spending a lot of time in debugging.

After all it was only a piece of advise.

I agree: it is indeed a valuable piece of information. I simply added a common sense based observation.

is this conversion from a char buf to a wchar correct?

Re: is this conversion from a char buf to a wchar correct?

hi,

i want to ask a simple question related to my code here. I am using a MessageBox to show the user the estimated time of the battery. The start value is an ULONG which i put into my function as float seconds. The cond param is the returnstring of my function.

Is the conversion (because the wsprintf function does not understand the %f param for formatting) right ? And what could i improve ?

Thanks !

void gettimestring(float seconds,wchar_t *input)
{
	
	float minutes,hours;
	hours = floorf(seconds/3600);
	seconds -= hours*3600;
	minutes = floorf(seconds/60);
	seconds -= minutes*60;

	char buf[20];

	sprintf(buf,"%02.0f:%02.0f:%02.0f",hours,minutes,seconds);
	wsprintf(input,L"%S",buf);
}

bye,
gabbana

Try Win32 API "MultiByteToWideChar"

For example

int nSize = MultiByteToWideChar(CP_ACP,MB_PRECOMPOSED,buf,strlen(buf),input,sizeof(input));
input[nSize] = 0;

Okay thanks i will try it, i think i need first to look into the msdn what the params exactly mean.

Why are you using floats for such a thing?

gabbana14-Jul-08 2:12

Re: is this conversion from a char buf to a wchar correct?

14-Jul-08 2:12

The calcucaltion of the hours have decimal numbers. So I think i need floats at minimum or what do you mean exactly ?

CPallini14-Jul-08 2:25

Re: is this conversion from a char buf to a wchar correct?

14-Jul-08 2:25

I mean, for instance

7305 seconds = 2 hours, 1 minute, 42 seconds

for such a conversion floats are not needed:

int iTotSecs = 7305;
int iHours, iMins, iSecs;
iHours = iTotSecs / 3600;
iMins = (iTotSecs % 3600) / 60;
iSecs = iTotSecs % 60;

Re: is this conversion from a char buf to a wchar correct?

14-Jul-08 3:10

ohh yes that's right, but if i could remember the compiler put out some warnings and this was it i want to avoid.
