ASM or C/C++ .DLL needed
Bid Request Id: 59164

Description:
Please read the full bid request before bidding.
I need a DLL coded in Assembly or C/C++ that sorts records from a text file to another file. The input file will contain two fields per line delimited by a single character like "," or Tab (no text qualifier). The output file should be in the same format and sorted on the second field. For example:
Input file:
Saurabh,Gupta
ZZZ,Cdef
John,Smith
abc,xyz
Bill,Gates
Output file:
ZZZ,Cdef
Bill,Gates
Saurabh,Gupta
John,Smith
abc,xyz
If any record is does not contain exactly two fields, it can be ignored. Optionally, duplicate records may be omitted.
I already have a third party component to do this. But it has many features and checks I don't require (which might be slowing it down). The component takes around 26 seconds to sort a randomly generated file with 1 million entries (I have a VB program that does it in 32 secs!). The DLL must be a lot faster than this. Speed is *very* important.
I need to call the DLL function from VB, something like:
SortFile(InFile As String, OutFile As String)
It should return the number of records processed. If an error occurred, there should be a way to get the detailed error information. The function does not need to be asynchronous. It must support *very* large files.
If you have any questions please feel free to ask. This must be completed within a week (the sooner the better).
Deliverables:
1) Complete and fully-functional working program(s) in executable form as well as complete source code (ASM or C/C++) of all work done.
2) Installation package that will install the software (in ready-to-run condition) on the platform(s) specified in this bid request.
3) Complete ownership and distribution copyrights to all work purchased.
4) Sample VB code showing the use of the DLL.
Platform:
Windows 98 and later. Written in 32-bit Assembly (preferred) or C/C++. Will be called from VB6 application.
Must be 100% finished and received by buyer on:
May 3, 2003 EDT
Deadline legal notes: All times are expressed in the time zone of the site EDT (UT - 5). If the buyer omitted a time, then the deadline is 11:59:59 PM EDT on the indicated date.

Dear Saurabh Gupta,
Let me begin by saying that I am very much interested in doing this project for you. I am planning to write a demo DLL for your evaluation.
Before I start thinking about implementation, could you please provide certain details, in particular:
- Is there any max length of a field: absolute, known at compile time, known at run-time? If there is, what is it?
- Is there any predefined range of allowed text characters: absolute, known at compile time, known at run time? If there is, what is it?
- Is the sorting case incensitive? I assume 'yes' here, please correct me if I am wrong.
- Is there any limit, however large, on input file size? 2 Gygabytes?
- Any other specifics, along with a test file or two, would be appreciated.
First 2 bullets here are of particular importance. Also, please outline briefly the hardware on which you are measuring time performance.
Hope to here from you soon,
Vitaliy Pavlyuk
