Uncompress question.. Help, I'm desperate!!!

[softwareguy74]

Hi,

Here's the deal.. I need to be able to have my program uncompress a file that I have compressed and password protected with WinZip...

The problem is that I can't seem to find any code out there that will let me do this and at the same time be just as fast as WinZip..

I have tried all the interfaces to the Zlib dll but they are either very slow or don't have any way of dealing with password protected zips..

I ran across 2 products that are very good (fast uncompression and password cabable) but they are expensive..

I don't want to spend any money at this time.. I'm broke!!! There has got to be some free code out there that will let me do what I want.. I'm know I'm asking for a lot (fast, free, password capable..) but come on, it's the Internet.. Free is what the Internet is all about and I haven't had any troubles finding free code for other things...

Here is my plead:

Can someone provide me with some code that will allow me to uncompress a password protected zip file that is just as fast as Winzip or close to it? I don't mind distributing a DLL with it such as zlib or whatever..

Any help or guidance as to where I might find this would be appreciated...

I have already tried the code at vbaccelerator but they don't seem to provide password capabilties..

Thanks,

Dan

Not the best method, but you can Shell WinZip and then use SendMessage to go through the rest of the process.

What if the end user doesn't have WinZip? I forgot to mention that this application is going to end users so I can't assume they have any other software on their machine.. It needs to be totally self sufficient..

Thanks,

I've got a Project I found somewhere that lets you do that. I've zipped it up, and you can download it from:

Hope this is of help!

Thanks, but as I said earlier.. I need password cabability... I have already tried the program but it does not provide for any password entry..

try this, its 100% compatible with winzip features, password protection and its very fast.
