How do I make a console application that takes command line parameters? Currently I have this:

void main(char filename[])
{
  cout << "command line param is: " << filename << endl;
}

However, filename is NULL. I am using Visual Studio.NET. I thought I''d seen it done before in this way. ___________________________________________________________ Proceeding on a brutal rampage is the obvious choice. Where to find the intensity (Updated Jan 23, 2004)

hey...You need to use the parameters:

int main(int argc, char** argv)

the names are arbitrary but the types are not.

argc is the number of arguments sent plus one and argv contains them in the array.

Use getopt to work with command lines.
