Hi,
I am trying to make my life easier and write a generic error returning function.....so I dont have to rewrite modules depending on whether it will be a command line program or if its a GUI program (Yes I know command line programs can use ShowMessage...but thats not cool!)

So heres the question

How can I get a function to tell whether the program it is being run inside is a console application or a windowed program?

Cheers,
Johovishta

Here is a very crude method, but it works:

  try
    writeln('This program is a console program');
  except
    ShowMessage('This program is a GUI program');
  end;

If you use writeln() with the Output file inside a GUI program, you will get a I/O 103 error.
A better alternative is to check if the Output file variable is created or not, but I don't know how to code that.

I have found a better way: the IsConsole global variable.
