Question

I m trying to add my file in Visual Studio as command line parameters. I know my code works since when I use fopen("whole path here", "r"), it runs. I then add the file as a command line parameter instead, and I get no such file or directory. Any thoughts? Thanks.

Answer 1

Has your file path spaces? If so, you need to enclose it in quotes.

Answer 2

Are you sure the command line parameter is handled correctly? Temporarily replace your main() with this:

int
main (int argc, char **argv)
{
    int j;
    for (j = 0;  j < argc;  ++j)
        printf ("argv [%d] =  %s 
", j, argv [j]);
    return 0;
}

My guess is that you have file paths with spaces in them. Those have to be quoted on the command line:

C:> myprogram "c:Documents and SettingsAdministratorMy DocumentsTest.dat"

If this were unquoted, the test program would output:

argv [0] =  myprogram.exe 
argv [1] =  c:Documents 
argv [2] =  and 
argv [3] =  SettingsAdministratorMy 
argv [4] =  DocumentsTest.dat

Answer 3

You can always debug in Visual Studio what file name you are getting from the command line, and then you have an idea of what s wrong.
