Well after a vast amount of time trying to interpret the source of CE, I realized that not knowing how to code in Delphi was too large a barrier in understanding how a program like CE functions. I just want to be able to do simple, and single, functions like set a breakpoint or change a register (probably a little more complex) on a certain address in my own program. I am using C++ to code and I tried using some functions from the dbk32.dll in my own proggie to no avail.

Some assistance please! A block of code with comments or a source file would be greatly appreciated! Thank you. =]

zOMG! It's hoodles from mSecrets! (I think)

Anyways... I am a noob... but I try to help, so...

Since dbk32.dll is written in Delphi... and C++/Delphi functions (or at least the commands/instructions/codelines/BLAHs/whatevers/ are) very different. So.... wouldn't you have to convert the dll source from Delphi to C++, compile it, and THEN try to use it?

BTW, I'm pretty sure majority of the debugging (well at least kernelmode) stuffies is in dbk32.sys...

No, the main thing about dll's (and objects) is that they work on every language.

But simple stuff like settings breakpoints isn't in the dll though \(except the kernel option to change a register on a address and find what accesses)
for real debugging like setting a breakpoint and single stepping through the code you need to use the windows api. The main api calls are DebugActiveProcess,WaitForDebugEvent and ContinueDebugEvent

Actually the only thing i need to do is change a register on an address. I don't need to step through code or actual "debugging" functions like that as of right now.

I realize that I can use the functions in the dll, that's the point of a dll =P I just need to know which to use and what parameters. =]

I also want to use the kernel mode functions opposed to the usermode anywayz, so I guess that just works out.

[Dark Byte]

There is a function called changeregonbp , It takes as param the processid, the address to change and lots of other parameters to define what registers to change and change to what. (don't know them out of my head, but look at the function declares)

when that has been enabled the kernel will change the registers to what you want when it detects a hardware breakpoint at the address you specied.
To set a hardware breakpoint set the debugregister you want. (also keep track of what debugregister you use because you need to give that to the driver, 0,1,2 or 3)

sounds good =] Thanks db
