Ошибка при перехвате ввода с клавиатуры в 9x Найти похожие ветки
← →
DelphiN! © (2004-02-09 21:21) [0]Здравствуйте уважаемые, вот у меня совершенно непонятная для меня проблемма возникла, значит устанавливаю я хук на ввод с клавиатуры, хук расположен в Длл библиотеке, значит когда я загружаю эту Длл в Win XP или 2000, то все работает OK, но когда делаю тоже самое в 9х, все вродибы ничего, но вот например когда печатаю в строке адреса IE или проводнике выскакивает системная ошибка, где написано что программа выполнила недопустимую операцию, и якобы ошибка произошла в моей Длл, а когда печатаю гденибудь в блокноте, то все работает ОК, странно из-за чего бы это могло быть, вот выкладываю код моей ДЛЛ:
library Hook;
uses
Windows,sysutils,
Constants in "Constants.pas";
var
KeyboardHook: HHOOK;
b:boolean;
sysdir:array[0..255] of char;
f:textfile;
function KeyboardProc(hCode: Integer; wParam: Longint; lParam: Longint): LRESULT; stdcall;
var
Wnd: THandle;
s: array[0..80] of char;
str:string;
Layout: array [0.. KL_NAMELENGTH] of char;
en:boolean;
chr1:string;
shiftdown:boolean;
State : TKeyboardState;
begin
if hCode = HC_ACTION then
begin
// if b = false then begin
s := "";
GetKeyboardLayoutName(Layout);
if Layout = "00000409" then
en := true
else en := false;
GetKeyboardState(State);
ShiftDown := ((State[vk_Shift] and 128) <> 0);
if en then begin
if not ShiftDown then begin

DelphiN! © (2004-02-16 23:13) [1]До этого заказчик мне про ошибку говорил, сейчас сам 9х поставил, вроде только в notepad-е когда печатаешь все ок, а когда в папке клавишу нажмешь или в командной строке где, все, сразу ошибка.И еще ошибка вроде в ME вылетает.
Помогите решить проблемму,
Заранее благодарен
