Shit's dead as fuck :\

Fasm snippet to fade a window in, called either in WM_CREATE or after window creation:

fade_time = 1000

; start fading
        invoke GetWindowLong,[hWnd],GWL_EXSTYLE
        or eax, WS_EX_LAYERED
        invoke SetWindowLong,[hWnd],GWL_EXSTYLE,eax
        invoke GetTickCount
        mov ebx, eax
   .sfade:
        invoke GetTickCount
        sub eax, ebx
        cmp eax, fade_time
        jge .efade
        shl eax, 8
        cdq
        mov ecx, fade_time
        div ecx
        invoke SetLayeredWindowAttributes,[hWnd],0,eax,LWA_ALPHA
   ; check for window messages so it can still be controlled while we fade

and for fading the window out just put "xor eax, 00FFh" after the div ecx.
