Introduction

QuickWin is a window application that spawn a Win32 console application redirecting his
stdin, stdout and stderr handles to a window. The console application is hiding and all
I/O operations are made through QuickWin.

This is a very useful program to spawn script programs or console applications in a
window environment without opening a DOS box.

How QuickWin works

QuickWin contains one or two windows depending if you want the same stdout view for stderr
output or another view. Stdin is in the same view as stdout. The view is a CRichEditView
and is not limited in space for the Output. Command like cut, copy, paste, find are also
available. QuickView can spawn console applications, shell (COMMAND.COM or CMD.EXE) or batch
files. You start the console application from command line or browse your disk. You can also
stop and restart the console application many times. The content of the output view can be saved
into file. The last 10 programs are saved into the registry and available for quick start.

The following parameters are available:

Full or Half duplex.

In full duplex, characters are send to stdin and displayed into the view. In half duplex, they
are only send to stdin.

Enter.

The enter key (CR) can be translated into CR, LF or CR+LF.

Close on Exit.

If the console application is terminated, QuickWin will terminate.

Show Child window.

You can display the DOS box child window. If you want to write into this “Console”, open
the “CON” file and write into it.

Oem -> Ansi.

Normally, we must translate characters for console application.

Use Input buffer.

If it is not necessary to send each character, one at a time to the stdin, character can be
written into an input buffer until CR is pressed.

Command line.

For COMMAND.COM or CMD.EXE, the command is echoed to stdout. This option
removes the tipped command.

Options for COMMAND.COM or CMD.EXE.

Full duplex, CR->CR+LF, Oem->ANSI, Use input buffer and Command line.

For standard applications, remove the Command line option.

Main interest in source code

A CRedirect class that can be used in any WIN32 or MFC applications. This class contains
four virtual functions for notification.

virtual void OnChildStarted(LPCSTR lpszCmdLine);
virtual void OnChildStdOutWrite(LPCSTR lpszOutput);
virtual void OnChildStdErrWrite(LPCSTR lpszOutput);
virtual void OnChildTerminate();
