[Alex Bránya]

Here is a code, if I'm right:

#include <iostream>
using namespace std;

int main(int argc, char* argv[]) {
   cout << argv[0];
   return 0;
}

thanks Alex but where i put my path of file ? like this c:\document\d.d oc to open this file?

Sorry that I misunderstood your question.

So you want to open a file in your program, and you would pass the filename as an argument to your executable, am I right?


You can do it in a command line, or a batch file, or
even with a call from other program. If you want to do
from your program, it's possible too, but a bit "harder" :)

The simple method is from command line:

yourprogram.exe  "pathname"

[saharit]

yes, u right but where is the argument that i use :(?

[Alex Bránya]

All arguments of your program in argv.
The argv[0] argument is automatically filled up
with the program's path.
The first argument you passed to your exe in command line
will be in argv[1].
The second one is in argv[2] and etc.
