Syntax for deleting specified file ( in C++)

[Mr Gates]

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?

[cscgal]

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

BOOL DeleteFile(
  LPCTSTR lpFileName   // pointer to name of file to delete
);

[Mr Gates]

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.

thanks Bob :)

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.

Are those suppose to be horns? They look like donkey ears.

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.

#include <stdlib.h> // needed to use system&#40;&#41; function

int main&#40;&#41; &#123;
     system&#40;"del dafile.txt"&#41;;		
     return 0;
&#125;

Ebil cscgal :twisted:

Anyway, how would I do that so it deleted the file at closing?

[samaru]

What do you mean at closing? When you close your program? If so, just make it one of your last lines.

Use the remove function ..ok BOB.. but how do i use it ,, syntax etc...
please bob, it's an emergancy.

[Bob]

In header :
int remove(const char* filename)

Probably too late for you by now, as you needed an answer urgently. I hope you had the sense to look up remove() in your C++ book, or do a Google search.

you can register a function that will be called when the program terminates with the atexit() function. this func could tehn call remove() on the file.

what is the difference between remove and del ?

Go easy on me. I'm trying to teach myself c++ and its a slow go for me. Just me, my book, and Google.

FYI... im wanting to write a program that goes through and deletes files of a certain extension. (sort of a janitor utility)

some proprietary software makes these files and will eventually fill up a hard drive. i just want a simple program I can run to clean the directory.

Thanks
