Saving ResultList as binary file

Question

Hi,
I like to store my ResultList as binary on file drive. The aim is to safe drive space and execution time for creating the report (XML or ASCII) for each UUT.
At the moment i had nothing figured out doing such stuff in TS.
Thats the reason why I started this thread to discuss with you what is possible or impossible.
Do not care about the programming language. LV,CVI,C++,C# or anything else is welcome.
My idea sounds simple
1.) Creating : Take the address space of the ResultList and save it to disk. Problem: Size of Buffer !!
2.) Consuming: Take the Binary file and put it back to TS and let a the TestReport (XML, ASCII or whatever you want) Callback running.

Hi Johann,
Thanks for your answer. But unfortunately it pointed not out what I really want to know. Or lets say what i want to discuss.
The major task is: Is there a way to safe a the complete ResultList (if you take a look into the TestReport-Callback it will be variable "Parameters.MainSequenceResults") as a binary-file without any modifiactions or generator/parser stuff.
The first aim of this procedure should be no loss of data by saving huge number of file drive space. The Second is saving execution time for generating the report file in the Testreport callback.
The last few "lunch-breaks" I have dealed with this question to figure out a useful solution.
I have found several things in TS4.0 that deal with this topic the serialization of data
One the one hand there is a Engine method "SerializeObjects" . I got this running (I hoped so) for binary data but for re-building
just for visualizing the data to an Operator. I found no running solution. On the other hand there is PropertyObject method
"Serialize" This stuff was working fine. But data always have been stored in INI-Format on file. So there was no great benefit
on file size.
While looking on the TS4.0 poster on the wall i was focused on PropertyObjectFile. And with it found a resonable solution for this task. It is simple. Create a  PropertyObjectFile, do some settings like binary and path, get the parent PropertyObject from it, and ceate a new varaiable in the data folder. Now take the ResultList, clone and add it to your variable. The last step is saving.
A comparsion to the XML-Report (shipped with NI)
Binary  <-->  XML
Filesize: 23 kB  <--> 2202 kB  that is a reduction of filedrive space of over 95% !!!
Executiontime 160ms <--> 1960ms  that means i have to spent only 8% of time as in XML
I have attached an example. It writes the report on Root C:\report.dat
For you and all other members feel free to test it and please tell me what you think about it.
If there is an other solution so lets discuss it.
