How Link File as an input arguent 1

[shaharpan]

Hi! All,

I am running VC++ , my project requires to read a file as an argument and generate a new file as an output argument.

I am able to compile the code from command prompt

C:\project\list.exe test.txt out.txt

here test.txt is the input for the program

and out.txt is the file used for output.

but there is way to configure this link using VC++ menu , properties or setting.

I need to configure these in VC++.

Please let me know the steps .

bcoz when i compile the code from VC++ its gives me

an error : Usage:directory <inputfile> <outputfile>Press any key to continue

THAT MEANS ITS NOT ABLE TO ACCESS THESE FILES

my code

void main(int argc,char *argv[])
{
if (argc !=3)
{
cout << "Usage:directory <inputfile> <outputfile>";
exit(1);
}

fstream readStream(argv[1],ios::in);
fstream writeStream(argv[2],ios:ut);

if (! readStream.is_open() || ! writeStream.is_open()) {
cout << "Cannot open input/ouptut files. Try again!";
exit (1);
}


please tell me how do i run this code from vc++ , gui

and how do i link the input and output files.

thanz in advance.

It is different in different versions of VC++

In VC++ 6.0
Go to Project->Settings, then switch to the Debug tab and type in your program arguments into the Program arguments text box (e.g. "test.txt out.txt" without the quotes).

In VC++ 7.1
Go to Project->Properties, Switch to Configuration Properties->Debugging, and type in your program arguments into the Command Arguments text box (e.g. "test.txt out.txt" without the quotes).

In other versions it is probably something similar.
