PKUNZIP from VB4 V2
*******************
*1996 CB Unlimited*
*******************

This sample code is a improvement on my original uploading
It allows you to control PKUNZIP, and therefore unzip files, from VB4

Unlike the previous upload that couldn't close the window when the zipping was finished, this example can.

There are two important functions in the bas module:
	ShellAndClose(CommandLine)	'Use this to shell to your dos program
	FindWindowLike			'This is called by ShellAndClose to find 					any windows with "Finished" in their title
					See KB article for more uses

This example uses the fact that when a dos box in Windows 95 has finished the title changes to "Finished - ....".  I think this probably limits this example to Win95 only, Sorry.

This code was written as a test for another of my projects ( a C&C savegame organizer)  and at the moment it will extract the files from a zip file and then search for files that are relevant to playing C&C

LEGAL AND OTHER STUFF
A lot of this code is based on code and material in the Microsoft KB help files.
I have adapted, fiddled, altered, and generaly played with the information in the files until I got the solution to my problem.
