Process End

[mabdelouahab]

Hi there guys
For special reasons, I've been away from the Forum
But I came back quickly
And now I have a question

how to i can trace the event of (Current Process End or Terminate),If possible, and if it exists, like WM_CLOSE or WM_DESTROY in window
I mean, in any type of programs, Console - Win32App ...

Any idea please

+ I'm sorry for my English

[TouEnMasm]

a debugger is the perfect tool to do that (windbg can read the dll code).

hi ToutEnMasm;
To clarify, I want a way to impose a program that invoke  'ProcEndp'  when it ends

Code Select Expand


include masm32rt.inc
;.............................
.code
ProcEndp PROC
;.............................
ret
ProcEndp endp

start:   
;.............................
end start



How can I impose that the procedure 'ProcEndp' will be invoked  when the Process is closed by windows  or when it is terminated
I want to make the Event END related by Invoke  'ProcEndp'

[mabdelouahab]

Is there a particular EVENT when the expiration or termination of the program

for GUI programs, there is a system of messages

for console mode programs, you can use SetConsoleCtrlHandler to set an event handler

you could also use GetConsoleWindow to get a handle and subclass WndProc - then use the GUI methods

Or you can try the CRT atexit or _onexit functions. You'll need to run this code from a command prompt to see the output from the procedures.

AtExit1 proc C

AtExit2 proc C

AtExit2 endp

start:

    ; _onexit returns a pointer to the function for success, or zero for error.
    ; atexit returns zero for success, or non-zero for error.
    invoke crt__onexit, OnExit1
    printf("%d\n",eax)
    invoke crt__onexit, OnExit2
    printf("%d\n",eax)
    invoke crt_atexit, AtExit1
    printf("%d\n",eax)
    invoke crt_atexit, AtExit2
    printf("%d\n",eax)   
    inkey
    exit
end start

And I get no output if I terminate the app from Task Manager.

Welcome back to the forum. :-)

You control your program, so in your message loop exit you call EndProc, then ExitProcess.
If someone else uses TerminateProcess, you don't get any notifications

A process cannot prevent itself from being terminated.

I thank you all
I thank you MichaelW, That's exactly what I 'm looking for, I will try if it works
