Hello

To compress ( backup ) data, we use 7Z.EXE as follows :-

ID_Run="/c 7z a -tzip "+qzipname+" "+qfiletoZip+" -y" 			
runshell(ID_run,,,.f.)

However, more and more of our clients are having their command prompts 
disabled, and are blocking external programs - in this case 7Z.EXE

Is there any other way to compress/zip files from the system ?
They will need to be passworded

Thanks
Chris

PS: Version 2.00.554

You can use CreateObject("Shell.Application") and add files into .zip (via OS).

There was discussion here some time ago here in one of groups and it works
allright for regular .zip files.

hi,

use for "Copyhere" API Function this Way


FUNCTION ZIPFILE(cZipFile,  cDestFolder)
/**********************************************

Hello Jim:
good afternoon.
Sorry to bother you.
The problem is that I tried of many ways to zip the files according to 
the example posted here and I did not could to do it.
Could you, or any other, being patient with me and take a look in the 
test attached and to point to me how (and if it is possible) to correct 
the problem?

hi,

you are right, something is going wrong

 OK
oShell    := CreateObject("Shell.Application")
 not create ?
oNameSrc  := oShell:NameSpace(cZipFile)

i have to make more Test why it don't work any more

---

as i normal use single files, not folder, have a look at

public.xbase++.activex

Re: UnZip

you will find Info about ZIP Header and how to check if CopyHere() have
store files already before use next file to compress

the Error is in that line, right
but it say oNameSrc = NIL so it is the line before

---

it seems ZIP Header must create first so
   oShell:NameSpace(cZipFile)
can open it.

it is like a empty DBF just Header but now you can "APPEND" next

---

LOCAL aHead := {80,75,5,6,0,0,0,0,0, 0,0,0,0,0,0,0,0,0,0,0,0,0,0,0}

   nHandle := FCreate( cZipFile, FC_NORMAL )
   iMax := LEN(aHead)
   FOR i := 1 TO iMax
      FWrite( nHandle, CHR( aHead[i]) )
   NEXT
   FClose( nHandle )

    create COM Object
   
   oShell   := CreateObject("Shell.Application")
   oZIP     := oShell:NameSpace(cZipFile)

Hello Jim:
good afternoon.
I made some experiences with :CopyHere() and I attached here the new one 
program.
The problem that exists yet is that it is needed a wait time after 
:CopyHere() for all files to be processed. Please see the line 69 of the 
attach example.
Do you know how to calculate it?
Another annoying thing is that whem it finds an empty folder is given a 
message. Is it possible avoid it?

Hello Jim:
good afternoon.
Many thanks again.
I read all messages about ZIP it in the NGs.
I tried to use :CopyHere()  because it showed to be the best for my 
needs and depends on only of the OS.
Also I looked for how to wait for the :CopyHere()  finishing (according 
my knowledge) and I did not found out how. Furthermore how to avoid  it 
to show the message of empty folder.
Any way I thank you by yours patience and disposal in helping.

In time:
It has a solution that enters in infinite loop if it has empty folder:

do while oNameDest:items():count() <> oNameSrc:items():count()
    Sleep(20)
enddo

as i say : i do ZIP file so if it is a Empty Folder it does not have files 
...

YES ... you are on right Way

      FOR i := 1 TO nFiles
?        cFile := aFiles[i]
         oZIP:CopyHere(cFile,xFlag)               copy one file

          wait until all file are written
         
         xCount := 0
         DO WHILE .T.
            nCount := oZIP:items():Count()
            IF nCount >= i
               EXIT
            ENDIF

Hello Jim:
good morning.
Again many thanks

I tested the code using a folder and it worked (only with the message of 
empty folder):

oNameSrc:CopyHere(oNameDest:items(), nOperation)
nCount := oNameSrc:items():count()
                   
                       Espera encerrar a compactação
do while oNameDest:items():count() <= nCount
    Sleep(20)
enddo

Hi Chris,

how about xbzip ?
use like this:

oZip := XbZLibZip():New()

oZip:Open( salva )

oZip:ShowProgress := .t.
app := SetAppWindow()
oZip:Display( app )

if oZip:IsOpen(.t.)
    oZip:AddDir('*.DB?', 'M:\Vendas')
    oZip:AddDir('*.FPT', 'M:\Vendas')
    oZip:AddDir('*.XPF', 'M:\Vendas')
endif

oZip:Close()

Regards,
Edgar

Hi Chris,

Although I have not used Chilkat for ZIP file creation I have used it 
for other capabilities since I bought my license in April 2017 and found 
it solid.  In looking through the capabilities of the License Bundle 
(there are lots!!!) it has ZIP files creation capabilities including 
password protection.

It can be found at... https://www.chilkatsoft.com

I use the 32 bit ActiveX version and there is a 30 day trial.  Just 
check under the site menu option "Licensing".

As far as using the Chilkat Libraries I use there Visual Foxpro Examples 
for guidance.

Hope this helps... Jonathan

Hi Chris,

I use the AddZIP compression libs, but I don't know if they are still
available somewhere...

REgards, Thomas

>> They will need to be passworded

Ok ... Windows ZIP can decrypt Files with Passwort but you can not create
passworded ZIP with Windows OS

but that seems me the Problem : it need a Licence

as i know XbZLib does not allowed to create passworded ZIP ... but you will
find Source as Plugin

depend on what you want to store into ZIP you might can crpyt them before
store into ZIP or Cloud.
!Note : IHMO you always can see what is in a ZIP File so encypt Filename to
!

Good afternoon.
I attached an example of using Shell:nameSpace:CopyHere() for packing 
and unpacking files and folders for who wants to use it and, better, 
improve it.
