Недавно начал писать программу на masm'e c использованием WinApi функций. Появилась странная ошибка. Я не понимаю, почему. Оно сводит меня с ума. При создании окна вызывается функция, которая должна установить куррент дайректори в Modules (папка создана). При этом возникает ошибка 998: При чем, если вынести вызов функции SetCurrentDirectory не в отдельную функцию, а в WndProc, то все работает. Please, help!

Code (Text): IDButSort db 1 ... invoke CreateWindowEx, ..., IDButSort, ... masm превращает в Code (Text): mov al, [IDButSort] movzx ax, al push ax Таким образом, в стек запихивается 2 байта вместо 4-х. В результате стек становится несбалансированным (ибо CreateWindowEx честно вытолкнет 4 байта) и невыровненным на границу 4 байта. Последнее обстоятельство очень не нравится многим API-функциям. Возможные решения: 1. Убрать секцию .CONST, заменив все байтовые переменные на equ. 2. В секции .CONST сделать переменные dword'ами. 3. Перейти на fasm, не подверженный глюкам masm'а. 4. Писать без invoke. "push IDButSort" просто так не скомпилировалось бы.
diamond masm превращает в ... в стек запихивается 2 байта вместо 4-х На самом деле шесть, ты не учел предыдыщее 6A 00, а надо 66 6A 00.
q_q Действительно, не учел, спасибо. Впрочем, на остальные выводы это не влияет Но в таком случае логика masm'а мне вообще непонятна. Без push 0 это поведение ещё можно объяснить наследием 16-битного режима...
diamond на остальные выводы это не влияет Неоспоримо. логика masm'а мне вообще непонятна Наверное masm хотел сначала ноль (как слово, но пропустил 66h), а потом AX.
Спасибо. Сам не догадался бы. Поменял там на equ - заработало. Но вот другой код, ошибка та же. Я уже поменял на equ все что можно было, поставил везде push вместо invoke. DD вместо DB. Не понимаю я принцип этой ошибки. Помогите.

На этот раз, в отличие от предыдущего случая, ошибка никак не связана со стеком, а всё проще, действительно "Invalid access to memory location": вот здесь Code (Text): push 0 lea edi, isNumbRead push edi push 1 push CurNumbBuff push hFileTXT call ReadFile нужно писать Code (Text): push offset CurNumbBuff иначе получается, что функцию ReadFile просят прочитать байт по адресу, заданному в переменной CurNumbBuff, а имеется в виду, что прочитать байт нужно в саму переменную CurNumbBuff.
