Using 7za.dll 2

[jcarnio]

Hi,

I´m trying to use the 7za.dll (7ZIP at

http://www.7-zip.org)

on my VB60 project, but i don´t know how to do this job.

Any help would be appreciated.

Thanks,

Jackson Carnio ( From Brazil )

Hello Jackson,

I'm going to assume that you don't know where to begin, so let me give you the beginning.

Download your dll.
Set a reference to it in VB.
You can use the Object Browser (View menu) to look at the classes, methods and properties the dll supports.
Write code using those methods and properties.

Thanx Bob,

I already try this method, but this causes an error.
This is a COM mode DLL and must be refered inside the VB code, and what about the classes, methods and properties, I´m looking for someone that have this documentation or
an sample code to help me in this job.

Thanx anyway,

Jackson

<I already try this method, but this causes an error.

I don't understand what you mean when you say you "tried this method?" What method did you try exactly? As for error, what error did you get? (Perhaps "Compile error: User-defined type not defined"?)

<This is a COM mode DLL and must be refered inside the VB code,

Well, yes, that's true. However, you point that out as if it contradicts the information I've given you. It doesn't.

<and what about the classes, methods and properties, I´m looking for someone that have this documentation or
an sample code to help me in this job.

You might want to read faq222-2244 for more information about getting good answers. If you show us what you've tried, we can help you fix it.

Sounds like you need to contact the vendor to see if they have some sample code they can send you.

Hi! Bob and Chip

I´m very grateful for your reply.
I don´t want to bore you and I´m sorry for my bad English.
I´ll try to explain better:
I need to create a files compression and decompression routines in my VB application.
I chose the 7ZIP algorithm because it is a free code conducted by the GNU rules and I could distribute my application without problems of user licences, etc.
When I said that I tried this method I was mentioning
your directions (Set a reference to it in VB...), and
this action causes an error "Can´t add a reference to the specified file"
You suggestions are wellcome if you have another way to include compression and decompression resources in a VB application whithout using shell command.

Thank you,

Jackson.

Where, precisely, is this &za.dll file available from the website you mention. I can't find any such COM component there

 

[gmmastros]

Well, in that case I would recommend you use cgZipLibrary instead. It's also free. I've used this library before and it works pretty well.

Strongm,

The 7za.dll is avaiable for download at

http://prdownloads.sourceforge.net/sevenzip/7z423_extra.tar.bz2?download

There is a FAQ about it in

http://www.7-zip.org/faq.html

FAQ title:
How to add support for 7z archives to my application?

Thank you for your reply

Jackson

SevenZip has their homepage at:

http://www.7-zip.org/

There is also a support forum at:

http://sourceforge.net/forum/forum.php?forum_id=45797

I would suggest you start there, as they'll be more familiar with SevenZip.

Chip H.

The readme files make it pretty clear:

"... these DLLs don't use standard COM interfaces for objects creating."

 

[jcarnio]

strongm,

Ok, it´s my fault!, Sorry...
Is it possible to use a non "standard COM interfaces"
in a VB project ?
How can I do this job?

Thanks again

 

[strongm]

Not easily, no

 

[jcarnio]

Ok strongm,
Thank you very much anyway!

I´m feel better if I don't spend your time anymore.

I've been using this in an application and it works fine.
