anyone know why this code crashes?
im using a timer to process a few lines of code at certain intervals. 
invoke SetTimer,hWin,5,500,NULL

.ELSEIF uMsg == WM_TIMER

		   invoke SendMessage,hListBox0,LB_RESETCONTENT,0,0
         invoke EnumWindows,addr EnumProc,NULL

............
............

EnumProc proc eHandle:DWORD

invoke GetClassName,eHandle,ADDR clName,8
invoke lstrcmpi,addr clName, addr IEFrame
	.if eax == 0
	    invoke IsWindowVisible,eHandle
            .if eax
                invoke GetWindowText,eHandle,addr buffer,100
                    .if eax
                        invoke SendMessage,hListBox0,LB_ADDSTRING,NULL,addr buffer
                    .endif
             .endif
     .endif
mov eax,eHandle
ret

EnumProc endp
It appears that the line mov eax,eHandle is the problem. When i change this line to xor eax,eax the program doesnt crash but it also doesnt do what its suppose to do. anyone? The error message box stated: 
The instruction at "ox77e14abb" referenced memory at "0x00000000". The memory count not be "written".


thanks
smurf

To continue enumeration, the callback function must return TRUE; to stop enumeration, it must return FALSE.

the type of your enum proc (as a parameter for EnumWindows()) should be: EnumWindowsProc proc stdcall hWnd:dword,lParam:dword so actually your proc is missing one parameter hope this will help
