1. Case closed.
2. Dear Goku you ruinned the poor Leonid the Easter time.
3. Regarding the decrypting capabilities of VH2011 for the Defox IV this is Mr. Chen response to the question i put to him:

Hi GIV,

The new VFP Hooker 2011, the password is www.baiyujia.com.

VFP Hooker can fix the Defoxiv's p-code, but for some reasons I will not publish the plugin program,
so this DEMO VERSION can't fix the Defoxiv's p-code.

Please refer to vhtest\defoxiv.



best regards.

So Defox IV is not anymore a threat to us.
We hope it comes a better protection and i did not expect to fall so soon the protection of Defox IV.

Ok. I must confirm that this is the code from Load method of test.scx form. But still can't see the whole unprotected form. The link you provided above is unavailable for me. Must state that I consider that application is fully cracked only in the case you provide fully functional unprotected application with the same functionality (as I provided for VFP Compiler protected application http://www.foxite.com/archives/who-can-hack-this-one-0000260749.htm). In this case it must run with the password that you know, better of all with empty password or any password. You will be sufficiently close to it if you can get the whole unprotected form test.scx. While I see only the code above I consider you are still very far from cracking application.

Other link here. Or see attached one.

I get to the link and get unprotected application. Congratulations to Chen. But for some reasons it runs with errors. You may check it. The password is "veryverysecurepwd".

Leonid is arrogant and accept that your protection is not good in assambler to reconstruct the app remembers nothing is impossible

I sayd before and say again. Do not speak about your things saying the are better making other ones not good. Leonid says before that Refox XII level III protection is verry weak. This is not polite.... I stand before Goku.

I must confirm that Defox III and DefoxIV can be unpacked sucessfuly. I tryed the full version of VH2011 on two of those targets. Many of forum colegues know who are the targets. The recovery process is slow and a technical one but the sources are recovered 99,99%. The reconstruction of the original aplication is not a easy one and the Defox is the first protection that makes the restauration process a little bit dificult. For a skilled reverser is a relative simple job. I must congratulate Mr. Leonid for his hard work.

It's one of the most valuable protectors on the scene.
In my oppinion it's the best.
But.....
It can also be unpacked easely by skilled unpackers.
Great work Leonid Lepin.
