can you solve this problem???

hi
In VB6 there is a utility makecab.exe at
C:\Program Files\Microsoft Visual Studio\VB98\Wizards\PDWizard\makecab.exei copied this file and pasted into c:\windows\command
and then i opened command (DOS) and type
makecab and i got following

C:\WINDOWS\Desktop\23>makecab
Microsoft (R) Cabinet Maker - Version (32) 1.00.0600 (11/22/96)
Copyright (c) Microsoft Corp 1993-1996. All rights reserved.

MAKECAB [/V[n]] [/D var=value ...] [/L dir] source [destination]
MAKECAB [/V[n]] [/D var=value ...] /F directive_file [...]

source File to compress.
destination File name to give compressed file. If omitted, the
last character of the source file name is replaced
with an underscore (_) and used as the destination.
/F directives A file with MakeCAB directives (may be repeated).
/D var=value Defines variable with specified value.
/L dir Location to place destination (default is current directory).
/V[n] Verbosity level (1..3).

when i type: makecab test.txt test.cab
i got following
Microsoft (R) Cabinet Maker - Version (32) 1.00.0600 (11/22/96
Copyright (c) Microsoft Corp 1993-1996. All rights reserved.
100.00% - test.txt (1 of 1)
and cab file (test.cab) created in current directory

my question is that how can i make cab file compressing multiple files into a single
cabinet (cab) file ,using makecab.

or if you know its uses in vb
thanks

To put several files into the same cabinet file you have to create a "MakeCAB directives file". It's a pure text file containing directives and a list of files to be compressed. All directives starts with a dot (or period), for example:
.Set CompressionType=MSZIP

The file can also contain comments, a line with a comment starts with a semicolon. Comments are ignored by MakeCAB.exe. Here's an example of a Directives File:

Code:

---

; Sample file... this is a comment BTW :-)
.OPTION EXPLICIT
.Set CabinetNameTemplate=NameOfCabFile.cab
.Set DiskDirectoryTemplate=CDROM ;This will put all files in the same CAB file (no span)
.Set CompressionType=MSZIP
.Set Cabinet=ON
;There are many more variables that you can set... But this is just a sample :-)
;*** After the directives you just list the files that should be added to the CAB ***
MyFile.txt
AnotherFile.doc
ThatFile.xls
ThisFile.vbs
;.... and so on... You can use relative path for the files, that is relative to where you
; place this file

---

Now save that as a *.ddf file and use MakeCAB like this:
MakeCAB.exe /f sampleFile.ddf

For more info, download the Cabinet SDK from Microsoft. It includes some *.doc files and one of them explains everything about how to use MakeCAB.exe.
