Memory locations in other programs

[leppert]

In a Win32 API environment, how would I go about finding the memory
location of a specific text box in another running, closed source
application? I need to read/write from a few boxes in the program from
time to time.

Thanks for any help or pointers (no pun intended).

Hi,

Try to use the following API's to read/write a process's memory:

OpenProcess()
VirtualQueryEx()
ReadProcessMemory()
WriteProcessMemory()
GetProcessWorkingSetSizeEx()

http://msdn.microsoft.com/library/de...penprocess.asp

http://msdn.microsoft.com/library/de...ualqueryex.asp

http://msdn.microsoft.com/library/de...cessmemory.asp

http://msdn.microsoft.com/library/de...cessmemory.asp

http://msdn.microsoft.com/library/de...gsetsizeex.asp

Hope these information helps,

Kellie.

Hmm.. for that you would need kernel code that is able to see detect the
structure of the program in memory and how any relevan DLL's may have
been relocated in memory. But, unless your kernel drive gives the data
to you directly (or change your process' security) you won't have access
to the string from your process.

You could also try to enumerate the windows and the childs and then use
GetWindowText() passing it the address of a global memory area which
you know (by means of global DLL code injection) is in a fixed virtual
memory location in both (or all) processes.

Here is a pointers for more discussion on the matter:
msdn.microsoft.com/library and www.google.com
....the Search field in both....
