Hello every one. I decided to learn FASM cause i was sick of C#. So i started of with some basics and now i want to close TaskManager with the SendMessage API. But i get this error with the SendMessage part (Invoke Send,Message,ebx,_f,_g,0) If some one could correct and explain the errors i made in the program i would be very greatful for your time. The code i have made so far is below.

Code:

format PE GUI

include 'C:\fasmw164\INCLUDE\win32a.inc'
mov ebx, FindWindow + _window +  _windowName
Invoke SendMessage,ebx,_f,_g,0
Invoke ExitProcess,0
 

_f db '0x0112'
_g db '0xF060'
;using Spy++ from VC++ 6 i found the task Manager ID thingo
_window db '#32770',0
_windowName db 'Task Manager',0

data import
library user32,'user32.dll',kernel32,'kernel32.dll'
include 'C:\fasmw164\INCLUDE\apia\user32.inc'
include 'C:\fasmw164\INCLUDE\apia\kernel32.inc'
end data

hopefully, this might help you a bit

Code:

format PE GUI

include "%fasminc%\win32a.inc"

invoke  FindWindow,NULL,tmWindowName
        cmp eax,NULL
        je e1
invoke  SendMessage,eax,WM_CLOSE,NULL,NULL
invoke  ExitProcess,0
e1:
invoke  MessageBox,NULL,tmWindowName,tmWindowName,MB_OK
invoke  ExitProcess,0

tmWindowName    db 'Windows Task Manager',0

data import
library user32, "user32.dll", kernel32, "kernel32.dll"
include "%fasminc%\apia\kernel32.inc"
include "%fasminc%\apia\user32.inc"
end data

open up the Windows Task Manager window so that if you assemble the above code, it would close it down.

btw, you could set in ur pc env variables

Code:

path=C:\fasmw164
fasminc=C:\fasmw164\INCLUDE\

so that it looks more friendly Smile

and ease your task if you change path later.
