控制台程序接收键盘消息

DOS程序通过一个名为Winoldap的控制台程序来运行，而这个程序则是在32位Windows控制台窗口中运行。原理上，Winoldap利用x86的"Virtual86"模式来虚拟实模式。
创建控制台时，操作系统自动创建三个"标准"文件句柄。在高级控制台编程中，用两个API函数控制这些句柄

GetStdHandle和SetStdHandle

控制台使用的不是我们常见的Win32消息队列，而是事件队列。
事件队列和Windows消息队列差不多，不过是接收输入事件，而非消息。所以Spy++当然得不到消息

ReadConsoleInput可以用来获得控制台的输入，参考

MSDN给出了一个创建标准信息队列的例子

C/C++ code

#include <windows.h>#include <stdio.h>VOID ErrorExit(LPSTR);VOID KeyEventProc(KEY_EVENT_RECORD); VOID MouseEventProc(MOUSE_EVENT_RECORD); VOID ResizeEventProc(WINDOW_BUFFER_SIZE_RECORD);  int main(VOID) {     HANDLE hStdin;     DWORD cNumRead, fdwMode, fdwSaveOldMode, i;     INPUT_RECORD irInBuf[128];     int counter=0;     // Get the standard input handle.      hStdin = GetStdHandle(STD_INPUT_HANDLE);     if (hStdin == INVALID_HANDLE_VALUE)         ErrorExit("GetStdHandle");      // Save the current input mode, to be restored on exit.      if (! GetConsoleMode(hStdin, &fdwSaveOldMode) )         ErrorExit("GetConsoleMode");      // Enable the window and mouse input events.      fdwMode = ENABLE_WINDOW_INPUT | ENABLE_MOUSE_INPUT;     if (! SetConsoleMode(hStdin, fdwMode) )         ErrorExit("SetConsoleMode");      // Loop to read and handle the input events.      while (counter++ <= 100)     {         // Wait for the events.          if (! ReadConsoleInput(                 hStdin,      // input buffer handle                 irInBuf,     // buffer to read into                 128,         // size of read buffer                 &cNumRead) ) // number of records read             ErrorExit("ReadConsoleInput");          // Dispatch the events to the appropriate handler.          for (i = 0; i < cNumRead; i++)         {            switch(irInBuf[i].EventType)             {                 case KEY_EVENT: // keyboard input                     KeyEventProc(irInBuf[i].Event.KeyEvent);                     break;                  case MOUSE_EVENT: // mouse input                     MouseEventProc(irInBuf[i].Event.MouseEvent);                     break;                  case WINDOW_BUFFER_SIZE_EVENT: // scrn buf. resizing                     ResizeEventProc(                         irInBuf[i].Event.WindowBufferSizeEvent);                     break;                  case FOCUS_EVENT:  // disregard focus events                  case MENU_EVENT:   // disregard menu events                     break;                  default:                     ErrorExit("Unknown event type");                     break;             }         }    }      return 0; }VOID ErrorExit (LPSTR lpszMessage) {     fprintf(stderr, "%s\n", lpszMessage);     ExitProcess(0); }VOID KeyEventProc(KEY_EVENT_RECORD ker){    printf("Key event: ");    if(ker.bKeyDown)        printf("key pressed\n");    else printf("key released\n");}VOID MouseEventProc(MOUSE_EVENT_RECORD mer){#ifndef MOUSE_HWHEELED#define MOUSE_HWHEELED 0x0008#endif    printf("Mouse event: ");        switch(mer.dwEventFlags)    {        case 0:            printf("button press\n");            break;        case DOUBLE_CLICK:            printf("double click\n");            break;        case MOUSE_HWHEELED:            printf("horizontal mouse wheel\n");            break;        case MOUSE_MOVED:            printf("mouse moved\n");            break;        case MOUSE_WHEELED:            printf("vertical mouse wheel\n");            break;        default:            printf("unknown\n");            break;    }}VOID ResizeEventProc(WINDOW_BUFFER_SIZE_RECORD wbsr){    printf("Resize event\n");}

我就花点事件给你解释下
WINDOW_BUFFER_SIZE_EVENT 屏幕大小改变时发出 
MENU_EVENT 用户使用控制台菜单或工具栏时发出 
FOCUS_EVENT 控制台得到输入焦点时发出


这是内部实现，当然我们外部也可以获得。利用管道，然后GetStdHandle(STD_INPUT_HANDLE);

然后即可读取Console窗口的事件。

好久没见到这么值得我回，详细解释的帖子。希望对后面看帖的朋友有帮助


用钩子实现

C/C++ code

#include <stdio.h>#include <windows.h>HHOOK g_ms_hook = 0;HHOOK g_kb_hook = 0;LRESULT CALLBACK kb_proc (int code, WPARAM w, LPARAM l){    printf((w==WM_KEYDOWN)?"按下%c\n":"抬起%c\n",((PKBDLLHOOKSTRUCT)l)->vkCode);    return CallNextHookEx (g_kb_hook, code, w, l);}LRESULT CALLBACK ms_proc (int code, WPARAM w, LPARAM l){    if(w == WM_LBUTTONDOWN)        printf("按下左键\n");    else if(w == WM_LBUTTONUP)        printf("抬起左键\n");    else        printf("x:%d\ty:%d\n",((PMSLLHOOKSTRUCT)l)->pt.x,((PMSLLHOOKSTRUCT)l)->pt.y);    return CallNextHookEx (g_ms_hook, code, w, l);}int main (void){    g_kb_hook = SetWindowsHookEx (WH_KEYBOARD_LL,kb_proc,GetModuleHandle (NULL),0);    g_ms_hook = SetWindowsHookEx (WH_MOUSE_LL, ms_proc,GetModuleHandle(NULL),0);    if (g_kb_hook == NULL || g_ms_hook == NULL)    {        printf("安装钩子出错\n");        return 0;    };    MSG msg;    while (GetMessage (&msg, NULL, 0, 0))    {        TranslateMessage (&msg);        DispatchMessage (&msg);    };    UnhookWindowsHookEx (g_kb_hook);    return 0;};

注意：用钩子的时候可能出现PKBDLLHOOKSTRUCT未定义问题，在头文件windows.g前加入如下则可以
//该定义用于启动钩子的结构体
#define _WIN32_WINNT 0x0400
