Hi guys (and girls)!

I'm kinda new to this cracking scene.
Been learning from Krobar's great tuts
But now i'm encounting problems with non-working hmemcpy in WinXP.

Quote from krobar's tut:
bpx hmemcpy and push enter. Now F5 out of softice and click Check it Baby!

After about the 6th RET, we'll land here:


xxxx:0042F4CA 8B45F0 MOV EAX,[EBP-10]
xxxx:0042F4CD 8B55F4 MOV EDX,[EBP-0C]
xxxx:0042F4D0 E82745FDFF CALL 004039FC
xxxx:0042F4D5 751A JNZ 0042F4F1

We see a CALL just before a jump. Well we gonna trace INTO this call. F8 traces INTO a call (push F8 when we on the call line) and we end up here:


xxxx:004039FC 53 PUSH EBX<--we land here
xxxx:004039FD 56 PUSH ESI
xxxx:004039FE 57 PUSH EDI
xxxx:004039FF 89C6 MOV ESI,EAX
xxxx:00403A01 89D7 MOV EDI,EDX
xxxx:00403A03 39D0 CMP EAX,EDX
xxxx:00403A05 0F848F000000 JZ 00403A9A
:end of quote

So, how can I break into this same place of the code:
xxxx:0042F4CA 8B45F0 MOV EAX,[EBP-10]
I've already tried different breakpoints, just doesn't break in any near this.
Is it possible to break like this: "BPX 0042F4CA"? At least it seems not, cos I've tried it several times with different options.
And i've already read some help-files for breakpoints...

Thanks in advance, help noob.

There is no such thing as hmemcpy in W2K/XP/2003. You'll have to get some newer tuts or install W9X.

Hint for Google: +hmemcpy +"point h"

To Bilbo: Has the "point h" that Ricardo described in his tuts worked for you?
So far I have not had any luck, or I am missing something. . .

Sorry, naides,
I'm not currently involved in this kind of stuff.

In case you missed it, this thread seems very exhaustive
http://www.exetools.com/forum/showthread.php?t=4323

I can find the sequence of bytes mentioned in the thread above inside the internal function USER32!ECGetText(), in my XP box, which is called from EditWndProc(), so - on a theoretical point of view - it should work!

And Ricardo posted the tools in that thread this morning. For those challenged by the 3 post rule there, I am attaching those tools here.

Regards,

Here's the other one, as only one attachment is allowed per post.

Don't forget there are point.h tutorials in here

Thanks for help, guys
From now on i'm trying to manage on my own.

That's the attitude.
