Syntax for deleting specified file ( in C++)

Expand Post »

I've made a program that creates a log of the activities performed in it, for easy reference for the user. But I want the program to automatically delete the file after the program is shut down. What is the syntax and how do I go about doing it?

Re: Syntax for deleting specified file ( in C++)

If you're writing a Windows application, try the DeleteFile function available in winbase.h:

C++ Syntax (Toggle Plain Text)
BOOL DeleteFile(
  LPCTSTR lpFileName   // pointer to name of file to delete
);
BOOL DeleteFile(
  LPCTSTR lpFileName   // pointer to name of file to delete
);

Re: Syntax for deleting specified file ( in C++)

the program was written to run in command prompt/dos, and I still can't get it to work. any other suggestions?

Say I tried to do it with windows, where would I specify the file I wanted to be deleted with the syntax you just gave me?

To delete a file use the C++ remove() function.

You're welcome.

Now, please post again. That 666 (posts) is making me uneasy ;-)

Oh, goodness gracious! I guess it would be most appropriate to make this my 667th post then.

Re: Syntax for deleting specified file ( in C++)

An easy way to delete a file is to just call a system command from Windows. dafile.txt is the file you want to delete.

C++ Syntax (Toggle Plain Text)
#include <stdlib.h> // needed to use system() function
 
int main() {
     system("del dafile.txt");		
     return 0;
}
#include <stdlib.h> // needed to use system() function

int main() {
     system("del dafile.txt");		
     return 0;
}
