use \" instead of "

Hello everyone,

If I only know the binary address of an instruction of a current process, for example, address 0x12345678, is it possible to print stack trace from the root caller to the specific address using WinDbg or some other tools?

thanks in advance,
George

Mr G George,

If you go to general programming, then thread, processes, & IPC, the first article there is called "walking the call stack". It sounds good for you.

Plz sir... ^CPallini ^CPallini abuz drugz, plz plz help urgent.

Thanks Iain,

Great article. My further question is, if there is an arbitrary address (e.g. 0x12345678), how to check whether it is code or data or stack? Any command to display the information (suppose I have symbol file) in the arbitrary address?

regards,
George

Hi George,
Whats up?
did you you see Thread section on the codeproject.com and codeguru.com

Thanks Hamid,

Any recommendations link?

stack trace is a report of active stack frames and shows where that error occurs I think now you want to get this report of an address?

Thanks Hamid,

My problem is,

1. My application breaks (e.g. uncaught exception) and report the breaking address is 0x12345678;
2. I want to know what code are executed at 0x12345678, and what are the call stack from bottom to address 0x12345678?

Any ideas?

regards,
George

Do you have source code of your program?

George_George30-Jun-08 18:48

Hi Hamid,

I am not talking about a specific program. But a general method to retrieve stack trace from a specific address. Any comments or ideas?

regards,
George

Hamid_RT30-Jun-08 20:16

30-Jun-08 20:16

Well I think there are no API for it I think you must be use of OS low level APIs or even assembly but I think most programs have a special register of current stack and address of caller's stack adress that you can use of them,but if you need to a tools see here[^]

George_George30-Jun-08 20:27

30-Jun-08 20:27

Thanks Hamid,

I prefer to use as least as 3rd party tools as possible. Currently, I am using WinDbg dv command, do you think this command could serve my purpose?

regards,
George

Hamid_RT30-Jun-08 20:46

30-Jun-08 20:46

I dont use of Windbg but I have good article about debugging I searched and I could to find its address see http://thermalnoise.files.wordpress.com/2007/01/debugging.pdf[^]

Thanks all the same, Hamid!

Let me know if you have any better ideas for my original question in the future. Smile | :)

That looks like a Java store to me. Leaves me wondering why would one write an antivirus in Java. Big Grin | :-D

Yes, Java is good for internet programming but may not be for antivirus s/w.

Clamwin which you recommended looks nice as it related to c++.

That looks like too much of an ambitious project to me, considering the fact that you want to do it all alone.

If you are wanting to do it from the scratch, there's too much for you on the plate. Start with file filter driver, executables (binaries in general), and more and more.

Alternatively, Google for Clamwin.
