Command line arguments

We have a Windows app we inherited that has the following logic:

It's meant to be run from the console, with command line args.  If no args are entered, then a form opens that allows the user to input the args.  Since this app runs as a scheduled job, we'd like to be able to include the args in the job.

No matter what we enter at the command prompt, the form opens.  It appears to be ignoring the args.

Is there anything we need to do within C# to signal the compiled version that args are expected?

Show us how you are reading the args in and processing them...

You need to change Program.Main function by the following way:

    static class Program
    {
        [STAThread]
        static void Main(string[] args)   // add string[] args
        {
            // Comment off existing code:
            //Application.EnableVisualStyles();
            //Application.SetCompatibleTextRenderingDefault(false);
            //Application.Run(new Form1());

            // Show form as modal dialog if there are no arguments:
            if ( args.Length == 0 )
            {
                Form1 form = new Form1();
                form.ShowDialog();
            }

            // Continue program execution here
            // ...
        }
    }

Small correction: you cam leave two lines

           Application.EnableVisualStyles();
           Application.SetCompatibleTextRenderingDefault(false);
