printf("%.2f\n", i*j); - I believe that should do the trick!

If I prefer use cout rather than printf
how can I do???

char szTemp[256];
sprintf(szTemp, "%.2f\n", i*j);
cout << szTemp;

You need to use an iomanip function. Unfortunately the VC 6 STL "documentation" is unhelpful, but something like:
cout << setprecision(2) << i*j; should work. The horrible docs and the complexity of using iomanips is why printf() is favored for this type of output.

I didn't know that the iomanip header file was part of the STL.

Hi friends!!!
I've created a server application and want to get its "uptime". What i want is that whenever server starts, it gets the system time and store in variable/s.
Now i want my client to send request to get the server uptime. Whenever the request arrive at server, it checks the time when request arrive and subtract previously recorded time from it and send the difference back to the client. Obviously the time difference will be server's uptime.
But i want the server's uptime to be in the format of (days:hours:minutes:seconds). How can i do so ????

Hi,
You can just use the CTime class to get that information. Then convert what you have into a string adding the ':' where you want it. Here's one example of how I use it to get the current date and store it in a CString.
CTime time = CTime::GetCurrentTime();
int month = time.GetMonth();
int day = time.GetDay();
int year = time.GetYear();
char tempMonth[50], tempDay[50], tempYear[50];
_itoa(month, tempMonth, 10);
_itoa(day, tempDay, 10);
_itoa(year, tempYear, 10);
CString sDate, sCurMonth, sCurYear;
CString sMonth, sDay, sYear;
sMonth = tempMonth;
sDay = tempDay;
sYear = tempYear;
sDate = sMonth + "/" + sDay + "/" + sYear;
Hope that helps you or at least points you in the right direction. Not sure on subtracting the time though.
Mike

See CTimeSpan. You'll want to use its Format() method.

I want to make a program that uses an interface like the one found on Norton SystemWorks and Firewall. It will have to be able to open and save files, though. How should I make it? Should I use SDI or dialog, and what kinds of controls are those that give it the different pages? Thanks.

Hi all, 
Is it possible for a program to get its own filename and path during run-time? Without calling the current directory function, because the current directory doesn’t necessarily have to be the same as the program directory. If so, then with what command or API function? 
Let us presume a program already knows its own filename and path, either gotten it during run-time or has it as a constant. Now is it possible for the program to alter its own executable program file? I am sure that it won’t get write access but I can’t understand why, when the program is running from the memory it shouldn’t affect it-self during run-time and therefore shouldn’t affect the OS. Is there a function that could give access for altering an executed program file, that is or isn’t the calling programs own executable file?
Please forgive me for any typos...

Thanks Michael! 
But what about editing the executable?

GetModuleFileName(NULL, &szFilepath, sizeof(szFilePath);
I have not looked at the FAQ but I assume it is in there. An FAQ is always a good starting point.

|

huh?
I meant... what about the altering the data in the executable it-self?
Is it possible for a program to alter its own executable program file or another already executed program's executable file??? hope you understod the question
Please reply anyone

Yes you can alter the data in an EXE file, providing that you can open it for writing.

Thanks Dominik!
This article is great, exactly what a needed, thanks again!

hi,
when i'm trying to create a ChooseColor dialog my app just crash and generated an unhandled exception.... then i've tryied to cretae a open filename dialog through GetOpenFileName and it worked. this is weird for me since both functions use commdlg.h and comdlg32.lib. i've initaliazed a very simple CHOOSECOLOR struct for my test :
static CHOOSECOLOR cc = {
sizeof(CHOOSECOLOR),
0,
0,
0,
0,
0,
0,
0,
0
};
any hint ?? thanks
haust

ok,
forget it. i've just discovered (from an exemple on code project ) that the lpCustColors member from the CHOOSECOLOR struct _must_ be valid.... i _thought_ that is was _optional_, it was _not_
well, i guess i've learnt something once more 2day....

I am working on a Windows Explorer style program and don't know to to get a CListCtrl to display files. I can get it to display hard drives but not the contents of folders. Is there a way to do this with a CListCtrl?
-- Steve
|

CListCtrl doesn't know anything about files / directories. You need to monitor the list view control
for (e.g.) NM_DBLCLK notifications in the parent window, or subclass the ListCtrl and use message reflection
to monitor for these notications.
Then refill the list with the contents of the double clicked directory. Or run the double clicked file.
If you are being very clever, you may want to look in the SDK in the Shell Interface COM area to let the
microsoft programmers do your work. But that is probably a little too complex... I wouldn't want to it!
Iain.
