Hello World

[Sourcerer]

I'm making a "hello world" program in C#, though a bit more complex one.

When I click on a button in my program, it is supposed to open a program (say,
Notepad) - that I did, by opening Notepad as another process. using Process
class.

Clicking another button, my program should make "Hello World!" appear in notepad
it's previously opened.

How can I do that?

to live after our own; but the great man is he who in the midst of the crowd
keeps with perfect sweetness the independence of solitude."

You probably can't. What you can do is to open a new copy of Notepad
with a selected textfile loaded by including the name of the textfile
as an argument when you fire up Notepad:

ProcessStartInfo PSI = new ProcessStartInfo();
PSI.FileName = "notepad.exe";
PSI.Arguments = "hello.txt";
Process.Start(PSI);

It's not the easiest thing to do. You could probably do it by using the
SendMessage windows API and send keystrokes to notepad.
