如何使用WriteConsoleInput/WriteConsole發送Return/Enter字符到控制檯

Question

我有以下一段代碼。我想發送命令「uci」，然後將Return/Enter發送到控制檯。但是，我沒有成功。請提供建議。謝謝！

#include <conio.h> 
#include <iostream> 
#include <windows.h> 

DWORD WINAPI test(LPVOID lp) 
{ 
    system("edit"); 

    return 0; 
} 

int main(int argc, char* argv[]) 
{ 
    /* 
    HANDLE hConIn = CreateFile("CONIN$", GENERIC_READ | GENERIC_WRITE, 
     FILE_SHARE_READ, NULL, OPEN_EXISTING, 
     FILE_ATTRIBUTE_NORMAL, 0); 
    HANDLE hConOut = CreateFile("CONOUT$", GENERIC_READ | GENERIC_WRITE, 
     FILE_SHARE_READ, NULL, OPEN_EXISTING, 
     FILE_ATTRIBUTE_NORMAL, 0); 
    */ 
    HANDLE hConIn = GetStdHandle(STD_INPUT_HANDLE); 
    HANDLE hConOut = GetStdHandle(STD_OUTPUT_HANDLE); 
    DWORD dwTmp; 
    INPUT_RECORD ir[4]; 

    CreateThread(NULL, 0, test,(LPDWORD)0, 0, &dwTmp); 

    Sleep(1000); 

    ir[0].EventType = KEY_EVENT; 
    ir[0].Event.KeyEvent.bKeyDown = TRUE; 
    ir[0].Event.KeyEvent.dwControlKeyState = 0; 
    ir[0].Event.KeyEvent.uChar.UnicodeChar = 'u'; 
    ir[0].Event.KeyEvent.wRepeatCount = 1; 
    ir[0].Event.KeyEvent.wVirtualKeyCode = 'U'; 
    ir[0].Event.KeyEvent.wVirtualScanCode = MapVirtualKey('U', MAPVK_VK_TO_VSC); 

    ir[1].EventType = KEY_EVENT; 
    ir[1].Event.KeyEvent.bKeyDown = TRUE; 
    ir[1].Event.KeyEvent.dwControlKeyState = 0; 
    ir[1].Event.KeyEvent.uChar.UnicodeChar = 'c'; 
    ir[1].Event.KeyEvent.wRepeatCount = 1; 
    ir[1].Event.KeyEvent.wVirtualKeyCode = 'C'; 
    ir[1].Event.KeyEvent.wVirtualScanCode = MapVirtualKey('C', MAPVK_VK_TO_VSC); 

    ir[2].EventType = KEY_EVENT; 
    ir[2].Event.KeyEvent.bKeyDown = TRUE; 
    ir[2].Event.KeyEvent.dwControlKeyState = 0; 
    ir[2].Event.KeyEvent.uChar.UnicodeChar = 'i'; 
    ir[2].Event.KeyEvent.wRepeatCount = 1; 
    ir[2].Event.KeyEvent.wVirtualKeyCode = 'I'; 
    ir[2].Event.KeyEvent.wVirtualScanCode = MapVirtualKey('I', MAPVK_VK_TO_VSC); 

    ir[3].EventType = KEY_EVENT; 
    ir[3].Event.KeyEvent.bKeyDown = TRUE; 
    ir[3].Event.KeyEvent.dwControlKeyState = 0; 
    ir[3].Event.KeyEvent.uChar.UnicodeChar = '\n'; 
    ir[3].Event.KeyEvent.wRepeatCount = 1; 
    ir[3].Event.KeyEvent.wVirtualKeyCode = '\n'; 
    ir[3].Event.KeyEvent.wVirtualScanCode = MapVirtualKey('\n', MAPVK_VK_TO_VSC); 

    dwTmp = 0; 
    WriteConsoleInput(hConIn, ir, 4, &dwTmp); 
    //FlushConsoleInputBuffer(hConIn); 
    //WriteConsole(hConIn, "uci\n", 5, &dwTmp, NULL); 
    //printf(" dwTmp = %d ", dwTmp); 

    Sleep(1000); 

    return 0; 
}

\n是一個保留關鍵碼;改爲使用VK_RETURN。
