Combining files.

[Qwert]

Hello,

is there a way to combine multiple files into 1 file with VB.NET?

Example:
Dim MyList As New ArrayList()
MyList.Add("File1.txt")
MyList.Add("File2.doc")
Pack(MyList , "AllMyFiles.dat")
....
Unpack("c:\MyDirectory", "AllMyFiles.dat" )
....

Thanks.

Qwert,

There are more ways.

One of them, create a dataset. Serialize the objects, place those in the
items. However you have to know the techniques for that, it is so much to
place that in one sample.

I hope this helps,

Cor

Microsoft Cabinet Software Development Kit

You can build CAB files using the "MAKECAB.EXE" utility that is IIRC
included in Windows. For extracting CAB files, you can use Microsoft's
"EXTRACT.EXE", which is available on the Windows XP CD or as part of the
Windows XP Support Tools:

Alternative you can use p/invoke on 'SetupIterateCabinet'. A VB6 sample can
be found here:

The Zip, GZip, BZip2 and Tar Implementation For .NET

The VB.NET Resource Kit contains zipping functionality too (note that the
Resource Kit is
not available any more, so the answer applies for the case that you already
have a copy of the Resource Kit):

The Visual Basic .NET Resource Kit
<URL:http://msdn.microsoft.com/vbasic/vbrkit/>

It contains ComponentOne Zip for .NET:

Using J#'s zip functionality:

Using the Zip Classes in the J# Class Libraries to Compress Files and Data
with C#

..NET 2.0 will contain ZIP support too.

Why not just put them in a zip file then have them unzipped. You can do this
programtically with Zlib.
