system function and Whitespaces - Windows

[jean.daniel.michaud]

Hi all,

Here is a little program:

// Snippet on
#include <stdlib.h>
#include <iostream>

int main(int argc, char **argv)
{
char *command = "\"C:\\Program Files\\PSPad\\PSPad.exe\" \"c:\\file
whitespace.txt\"";
std::cout << command << std::endl;
system(command);
return 0;
}
// snippet off

It just says that 'C:\Program' is not a valid command. But when I
type:

"C:\Program Files\PSPad\PSPad.exe" "c:\file whitespace.txt"

in a dos command prompt, it works. For some reasons I don't want to
use the 8 characters version (C:\Progra~1) which actually works.

Any idea?

This is nothing to do with C. Its all to do with how the Windows
runtime environment parses and executes commandlines wih embedded
spaces. You will need to ask in an MSWindows group for more advice.

my recollection is that you need to explicitly run a command shell

First, this poor guy just asked a simple question why you guys so
kindly
gave him so muchcrapy info. Only this one went straight.

Besides, he already said he is not good with C.

Just kidding. Don't know there are still good C people around.
