Modify UnZip SFX code

My apologies for individually posting this to multiple newsgroups - my ISP
won't allow multiple posts.
I'm not a C programmer, so I'm looking for someone to modify some UnZip code
for a Self-Extracting stub.

I have a copy of the source code of the UnZipSFX utility, also available
from :
http://sourceforge.net/project/showf...roup_id=118012

I need the following modifications made :

1. Change to default 'unzip to' path from the current path, and hard code it
to a specific directory.
2. Set the stub to automatically overwrite any existing files without
prompting.
3. Must accept a " /auto " switch as our existing application shells the
self extracting exe with that switch ( currently using a WinZip SE file with
the /auto for 'auto extract' ).
4. Once the stub is run, it must auto extract the data from the zip file
without any user interaction required.
5. If not too time consuming, strip out any code that is not required for
the above specs ( eg Password check, prompts, etc ) to help reduce the size
of the final compiled stub.
6. Source code must be returned to me in case we need additional
modifications in the future.
Any advice or pointers appreciated,
Regards
Dave

http://www.rentacoder.com/ might be a more useful place to ask. But if
you must ask here then at least give a hint how much you are willing to
pay for this work. I'm a little insulted by your post.

Hi John

Thanks for the rentacoder link. I'll look into this immediately.

Sorry you felt a bit insulted - no offence was intended with my post. I
don't know what the going rate is for a programmer, or how long this type of
change would take ( although the original author of the stub code did say
about 1 to 2 hours ), so I posted the specs of what I need in the hope of
finding someone who, based on those specs, knows that he/she can do the
project, and could give me a cost for the lot.

Regards
Dave

Well I was only slightly insulted, but you could have said 'I am willing
to pay a reasonable rate'. I think 1 to 2 hours is probably a slight
underestimate because the programmer will have to familarise themselves
with the code, something the original author wouldn't need to do. The
quality of the original source is obviously a big issue here.

I need to unzip all zip file(s) in the current directory into their own subdirectories. The zip file name(s) always start with the string "usa" and end with ".zip". The code below will make the subdirectory, move the zip file into the subdirectory, but unzips the contents into the root (current) directory. I want the contents of the zip file unloaded into the newly created subdirectory where the zip file is. Any ideas? Thanks.
