Пытаюсь инвертировать изображение (masm)

[EThread]

Пытаюсь инвертировать изображение по нажатию на кнопку IDC_BTN1.
Но на end start ругается: fatal error A1011: directive must be in control block
Подскажите, как исправить?

а почему у вас .endif закоментирован в конце ?

Вот код без ошибок, но не инвертирует:

Ошибку исправила. Теперь просто не инвертирует. Помогите, пожалуйста, не вижу в чём шибка...

[Ulex]

     invoke BeginPaint,hWnd, addr Ps
           mov    hdc,eax
           invoke CreateCompatibleDC,hdc
          mov hMemDC,eax
           invoke SelectObject, hMemDC, h_bitmap
           invoke GetClientRect, hWnd, addr rect
           invoke BitBlt,hdc,0,0,rect.right,rect.bottom,hMemDC,0,0,NOTSRCCOPY
           invoke DeleteDC,hMemDC
           invoke EndPaint, hWnd, addr Ps

Это надо в обработчике сообщения WM_PAINT писать.
Да и вообще я чего-то мало что понял.
Что за MyProc? Что такое aRC_GraphicEx_Init?
Ну и пожелание напоследок (если позволите) - не используйте на ассемблере if,for,while и т.п. инструкции. Код становится нечитабельным.
