Well, most of these posts are questions, but this one''s a tip. A while back, I was trying to figure out how to do the equivalent of the cls command for a MS-DOS console app. It turns out that you can emulate typing into the DOS shell with the system() function (in stdlib.h.) So, to do a screen clear, you''d go system("cls"). To start Notepad, you''d type system("start c:/windows/notepad.exe"). And on and on. Very useful. It seems, though, that using the cd command has no effect, so you must use _chdir() for this one. lntakitopi@aol.com | http://geocities.com/guanajam/

Forgot to tell you, it works in Windows apps too.

Yeah, that works, but it''s a bit slow though

the equivalent of the cls command in an msdos app?

memset((char*)0xb8000, 0, 4000);

hell of a lot faster than spawning a process

Well, of course using it for cls is slow... the use I liked was that you could run programs and open files so easily.

As goltrpoat alluded to, that command spawns a copy of the command interpreter (COMMAND.COM), which then executes your command, and exits.

Under Windows, I believe you can use the ShellExecute() function. This is cool because you can open documents, if they have a registered filetype.

e.g., ShellExecute(HWnd,"Play","C:\Music.MP3",NULL,NULL,WS_MINIMIZED)

or

ShellExecute(HWnd,"Open","http://mywebsite.com",NULL,NULL,WS_MAXIMIZED)

I didn't know you could use system() under Windows. Weird. I wonder if it is just a wrapper of ShellExecute or..?

Thanks. system() seemed too "DOSsy." (Hey, I invented a new word!)
