c++ - store number not i n file?

dawballz

Is there any way in c++ to store a number, but not in a file.
E.g I want to count the number of times the program is run.

Try using your fingers.

Or if you're on windows, in the registry.

Put in a database, oracle do nice ones and should scale to meet the needs of your application, plus is not tied to a platform.

lol!

If it is windows try using these :

SetRegistryKey(_T("My Programs 1"));

WriteProfileInt("Program Run", "Count", n);

GetProfileInt("Program Run", "Count", 0);

You do realise its probably going to take more code to write to a file and read back from it, than save to the registry.

main()
{
  SetRegistryKey ( "Program" ) ;
  int i ;
  GetProfileInt ( "Program", "Count", &i ) ;
 

  //................ Rest of application

  // Application ending
  i++ ;
  WriteProfileInt ( "Program", "Count", i ) 
  return 0 ;
}

What could be simpler, in all fairness.

Hell if you're going to be that lazy then just go with Rev's original suggestion.

Hmmmm.. ok then, i might just go with the registry one..
But I don't understand the code above..should Program be the name of my program?..

If I want to check how many times the program was run, what do I do...?
Is it just this line:
GetProfileInt ( "Program", "Count", &i ) ;
then say.. cout << i;
?

What header file do i need?
thanks,

You can do it in one line if your users will help

//
// Launch notepad and get the users to add their name and the time into it
WinExec("notepad.exe", 0);

btw when's this project due by ?

"Program" is whatever you want to call your project/programs key in the registry, call it whatever you want.

windows.h should do it, look in MSDN, my god your lazy :eek:

Yeah after GetProfileInt ( ) call, you have your information from the registry.

Mid March.
I think I don't really have to have the number of times the prog is run.
All I really need is to know if it is the programs first time to be run, so what I am doing is creating a file. Then, for every run, it checks if the file is there.
If the file is there, it is not the first time the program is ran, otherwise the program has been ran before...make sense?

Thanks for your help..
