Hi
Is there way to use "DataBP > Find out what access this address" window from lua script?

Let's say we have condition like:
Code:
if (EIP == addressOfFunk) then

and we know that (ESP + 8) = mem buffer ptr on this BP

How (if this possible) to set this memory access log bp (~100 bytes size) with default CE window?
As I know this step also require BP type changing (from HW to page exceptions).

pause the program
set the data breakpoint
go to the breakpoint list, select the breakpoint and rightclick it
then set the condition you want to break on

and then continue the program

Unfortunately I can't - this is server-client communication code and any delay > ~1000ms will cause connection drop and will change execution flow.

Any workaround (maybe without GUI, just log)?

Try this.
Set the pause option with Timer: 10.. 100.. 999 ..
Click Key: F8 pause - F8 UnPause

Code:
if myhotkey then
  myhotkey.Destroy()
  myhotkey = nil
end

function killmytimer()
  if mytimer then
    mytimer.Destroy()
    mytimer = nil
--showMessage("UnPause")
  end
end

myhotkey = createHotkey(function()
  if mytimer then
    killmytimer()
    speedhack_setSpeed'1'
--    unpause()
  else
    mytimer=createTimer()
    mytimer.interval=1 --10.. 100.. 999 ..
    mytimer.OnTimer=function()
    speedhack_setSpeed'0'
--    pause()
    end
  end

end, VK_F8)

Thx
But how this suppose to work?
Even if I froze client-side, server will drop connection and unpaused client won't get any packets to continue the right branch.

For now I have BP callback which handle BP chain, and eventually we get our mem buffer as a result of last BP. The point is to get all access to that mem buffer without pausing the program.
If client don't respond during timeout, server will close connection and we may get only first access event (or get nothing).

My guess was CE can do such a things without any problem, maybe I was wrong, just want to save some time, anyway this can be done with some coding but takes more time...
