Q: How to call compressed application from within another one?

if the first running application (starter) is compressed, then other protected application can be called by issuing the DO command or by instantiating a class

Q: What's the different between JCAL compression and ZLIB compression?
A:
ZLIB 1.2.2, Copyright ?1995 - 2003 by Jean-loup Gailly and Mark Adler
http://www.gzip.org/zlib/

JCALG1 r5.34, Copyright ?1999 - 2002 by Jeremy Collake
http://www.bitsum.com/#jcalg1

difference from the point of view of ReFox user: ZLIB works faster, JCAL gives better
compression (a little)

Q: I am getting an error message "This beta version of VFP has expired"
when trying to run Level III protected VFP6 executable

A: This problem can appear on the original VFP6 only.
If you insist on using VFP6, please apply any service pack. The latest one for VFP6 was SP5.


Q: How can I test that ReFox will really recover my lost source code

A: using the demo:
  • if demo shows snippets of code (several lines of each procedure), it is sure for 100% the code can be recovered
  • if demo shows hexadecimal code only, the code is either protected or it is not FoxPro code and ReFox cannot help you.

    Q: is there a trial version of ReFox (with full functionality)

    A: no, isn't, the reason is simple ...

    Apparently, it's so simple it escapes some readers. Care to expand a little?

    Um, because then there would be no reason to buy it?

    So it's somehow different from all the other applications out there that have fully-functional, time-limited trials then? -- Alan Bourke
    A: with the new demo the branding level III is fully-functional and can be used for trial time limited purpose -- Jan Brebera


    Q: I always split my applications into 1 EXE file plus a number of APP files. Is ReFox XI able to compress and brand (encrypt) external APP files from decompilation?

    A: The compression is applicable with EXEs only. In that case you have to combine EXE protected Level III (branded and compressed) and APPs protected Level II (branded only), and use the same password for all to generate the seed for branding procedure.


    Q: Can I call compressed EXE by issuing the DO command?

    A:
    Yes - if called from within another compressed executable (see answer above)
    NO - if called from within VFP IDE or from another not protected application
    Running compressed EXE needs the EXE-stub to be activated which starts the decompressor, while the DO skips the stub and runs the code immediately. Other levels of protection can be used with DO, if the external FXP, APP or EXE were protected with the same password as the main program.
