Two windows console programming questions (C/Win32)
Author
Question 1:
How can I run console command line parameters/commands directly from within a C program without it being messy?
Question 2:
What is the Win32 approach to single character input? I want to grab a single character in a console without an "enter" keypress from the user and then move on. I'm having a heck of a time finding exactly what I need here.
Thanks.
1) It'll always be messy. You just need to figure out which kind of mess you want.
2) Most compilers for Windows support a header called conio.h. In that header will usually be a function called getch() or _getch() that sounds like what you want.

Great, thanks. Looking into that further now.

Can you point me to a discussion of it or tutorial? I keep googling and it always gives me something unrelated since the search terms have so many other topics in common and so far msdn hasn't had anything explicit that I have found.
Look up the system(), ShellExecute() and CreateProcess() functions. Or if you're feeling especially masochistic execl(), execle(), execlp() and execlpe().
I never recommend using conio.h . It’s not like a third party library. It’s a compiler dependent library, with absolutely no standardisation. Instead, you should use the Win32 API to implement the equivalent of getch.

But it’s probably worth keeping in mind the fork/exec method on *NIX systems.

It's available via the MSVC CRT implementation, which means it can be used by programs compiled with MSVC or compilers that utilize the MSVC runtime like MinGW. See _exec on MSDN. Other compiler vendors like Borland support it as well.
