well ppl, after several requests to share my secret to ... ( you know ) ...

im willing to do that ... BUT ... for a price ...

my request is very simple ... GIVE ME THE WORLD

no ? ok, i'll sattle for a cent by paypal account.

no too ? fine.

as some of us know, in autoit there is no direct method to get address of variables or functions

what a shame, VERY VERY LIMITING.

there are several ways to bypass this limit, i worked it out. heres one, it involves writing the CALLBACK

in a different DLL and then using autoits DLLCALL to do ... another ... DLL CALL ( LoadLibrary() )

then, using DLLCALL and GetProcAddress() to get the function address

y, i know, VERY ... but it works

for my own testing i chose Win API - EnumChildWindows()

the dll i wrote is atteched so download and place it in the SAME dir where you save the script

otherwise, point $CallbackDLL to the right folder

enjoy

$ControlID = 'Sta'; $ControlID is the control text ( for this progy ),  Calculator MUST be in scientific mode



$WinHandle = DllCall( 'user32.dll', 'hwnd', 'FindWindow', 'int', 0, 'str', $WinTitle ); Get Window Handle

_ArrayDisplay( $WinHandle, '1' )

If $WinHandle[ 0 ] == '0x00000000' Then; DLLCALL Failed for whatever reason, no valid handle
    
    MsgBox( 0, 'Error', 'DLLCALL Failed' )
    
Else
