 Why doesn't this Shell command work? I am trying to view the contents of a .ZIP file. I am using the following
code in attempt to do it but I seem to have problems with it.
What happens is that the screen turns black and then comes back to windows.
I then check to see if c:\compress.out contains the output but the file
does't even exist.
I verified that txtSourceFile.Text is a valid filename and that it exists
before this code is executed. Also pkzip does recide in the dos dir.
Also if I try to execute the command without the > c:\compress.out at the
end it still doesn't show anything on the screen.
-------------------------------------------------------------------------
Sub Process_File ()
Dim DosCommand As String, X As Integer
DosCommand = "c:\dos\pkzip.exe -v " & txtSourceFile.Text & " > c:\compress.out"
X = Shell(DosCommand, 1)
End Sub
----------------------------------------------------------------------------
IF someone can figure out whats wrong with this or maybe if there exists a
VBX or DLL function that can do this for me Is appreciate it.
Thanks,

well, to the best of my recollection to use the ">" operator you have to shell COMMAND.COM /c then your command line. i.e rc = Shell ("Command.com PKZIP -V file.zip > c:\t,t",1) Does your file that you want to unzip reside in the current directory when
you shell ?

At first glance, it _should_ work. Of course, people say that programmers always give non-committal statements like that ("...so the changes we made should work just fine. You shouldn't have any more problems."). What could be happening is that it may be executing fine, but when the DOS
.EXE command ends, Windows closes the DOS session/window immediately, so
you don't get to see it at all. You may have to write a batch file that
has a PAUSE command in it, to wait for user input.
I don't know why the output direction doesn't work. Try directing the
output to c:\compress.out from the DOS command line and see if that works.
PKZIP may not support that (I don't know and am too lazy to check for
myself).
Also, your machine/windows configuration may not be able to run that
particular DOS command without a .PIF to tell it how to execute it. Try
setting up a .PIF and running that from the Shell() function.
Let me know how you fix it, if you don't mind.

Why doesn't this Shell command work? The same thing happened in my program. The reason you may be having problems with your code is because your try to load the output file before it is even there!!! :) I know this sounds weird. Let me explain.
mmand. That's why you get a file not found error.
The way I got around this was to make a loop - make sure you save your project before you try this!- checking whether the file is there or not. If is NOT there, then make the loop continue. If it's there continue on to the load statement.

Why doesn't this Shell command work? Another problem is that if the file is suppose to be in your app. dir. then make sure the path is set to: app.path= "Blah_Blah" in your VB code.

Why doesn't this Shell command work? This is if you read 9105. I have done this whole process before. If you want to view the file -try an easier way. Make a PIF, shell to it. Have the PIF run the batch file.
When the txt file is complete. Input the file and list each line in the a list BOX control.
*This way you can set the PIF file setting to run the batch window or iconized (or hidden if you use the WinExec API call)

_Either_ PKZIP or PKUNZIP should do this correctly. See the documentation. Aaron Barbour

Hi! Why don't you use the ZipInfo.VBX, which has been made for showing
detailled infos of .ZIP-Archives! (much more than names only!!!)
You will find it on any major VBX-FTP-Site, or eMail me!
ciao, Dino

You need to set up a new PIF file to run pkzip under windows. Use the PIF editor that comes with windows, and search the help on "PIFs, creating" Hope this is some use.

Wrong. He's using the correct command. It's pkZIP -v, not pkUNZIP. --

Wrong. Both PKZIP and PKUNZIP support the -v option. I think in older versions (eg 1.1) PKZIP did not have the option; PKUNZIP did.
