im probably annoying you guys with my posts, so if i am, im sorry. Well here is my story... i can't find an efficient loop, i have tried using .while/.until & .if/.endif but these make the CPU go straight to 100%. I sappose the program i made was poor and badly written but all i want it too do is too search for this particular window and kill it and if anyone is curious, its not for a crappy worm. Here is the code...

Code:

format PE GUI 

include "C:\fasmw164\INCLUDE\win32ax.inc"

.data
tmWindowName db 'Game Emulator',0

.code
start: 

start1:
push tmWindowName
push NULL 
call [FindWindow]
         .if eax,be,NULL ;around here is makeing it very slow
          jmp start1
          .endif
jmp start2


start2:
invoke SendMessage, eax, WM_CLOSE, NULL, NULL
jmp start1

.end start

All help and comments is greatly appreciated.

Thanks, Jack

If you want it to search for a particular window and kill it why are you using a loop?
Shouldn't you only have to find the window once and kill it? Your continually looking for it.
If you want your current code to not use up so much CPU then add a delay in it. Use the Sleep api in kernel32.dll and add a delay to your infinite loop.

.data 
tmWindowName db 'Game Emulator',0 

.code 
start:  

start1: 
invoke Sleep,100   ;<--- this line added
push tmWindowName 
push NULL  
call [FindWindow] 
         .if eax,be,NULL ;around here is makeing it very slow 
          jmp start1 
          .endif 
jmp start2 


start2: 
invoke SendMessage, eax, WM_CLOSE, NULL, NULL
