C++ h-GUI作为CMD

我是一名学生，我正在寻求帮助，所以我可以处理通过的项目。 我不会说一口流利的英语，因为我不是本地人，但相信我，我会尽力的

int main()
{
    HANDLE hStdOut;
    wchar_t s[] = L"reverse";
    CONSOLE_SCREEN_BUFFER_INFO ConsoleScreenBufferInfo;
    COORD dwWriteCoord;
    DWORD NumberOfCharsWritten;

    std::wcout << s << '\n';

    hStdOut = GetStdHandle(STD_OUTPUT_HANDLE);
    GetConsoleScreenBufferInfo(hStdOut, &ConsoleScreenBufferInfo);
    dwWriteCoord = ConsoleScreenBufferInfo.dwCursorPosition;
    dwWriteCoord.X += wcslen(s);
    for (int i = 0; i < wcslen(s); ++i) {
        --dwWriteCoord.X;
        WriteConsoleOutputCharacter(hStdOut, s+i, 1, dwWriteCoord, &NumberOfCharsWritten);
        }

    return 0;
}

我的教授希望我用C++中的“Windows编辑器”来制作“文本编辑器”，即控制台。首先，最简单的方法是最多打印6个字母，然后在屏幕上打印出来。第二，半格是最多6个字母，但每个字母在按下回车按钮后。第三，最难的是最多获得6个字母，但如果有更多的字母，文本应该被覆盖

int main()
{
    HANDLE hStdOut;
    wchar_t s[] = L"reverse";
    CONSOLE_SCREEN_BUFFER_INFO ConsoleScreenBufferInfo;
    COORD dwWriteCoord;
    DWORD NumberOfCharsWritten;

    std::wcout << s << '\n';

    hStdOut = GetStdHandle(STD_OUTPUT_HANDLE);
    GetConsoleScreenBufferInfo(hStdOut, &ConsoleScreenBufferInfo);
    dwWriteCoord = ConsoleScreenBufferInfo.dwCursorPosition;
    dwWriteCoord.X += wcslen(s);
    for (int i = 0; i < wcslen(s); ++i) {
        --dwWriteCoord.X;
        WriteConsoleOutputCharacter(hStdOut, s+i, 1, dwWriteCoord, &NumberOfCharsWritten);
        }

    return 0;
}

示例：E X A M p L E S->E S A M p L E S

int main()
{
    HANDLE hStdOut;
    wchar_t s[] = L"reverse";
    CONSOLE_SCREEN_BUFFER_INFO ConsoleScreenBufferInfo;
    COORD dwWriteCoord;
    DWORD NumberOfCharsWritten;

    std::wcout << s << '\n';

    hStdOut = GetStdHandle(STD_OUTPUT_HANDLE);
    GetConsoleScreenBufferInfo(hStdOut, &ConsoleScreenBufferInfo);
    dwWriteCoord = ConsoleScreenBufferInfo.dwCursorPosition;
    dwWriteCoord.X += wcslen(s);
    for (int i = 0; i < wcslen(s); ++i) {
        --dwWriteCoord.X;
        WriteConsoleOutputCharacter(hStdOut, s+i, 1, dwWriteCoord, &NumberOfCharsWritten);
        }

    return 0;
}

所以我首先需要一些线索或想法。其次，我需要一些帮助来理解Windows.h。我读了很多文档，但假设WriteConsole函数对我来说是一种黑魔法：

int main()
{
    HANDLE hStdOut;
    wchar_t s[] = L"reverse";
    CONSOLE_SCREEN_BUFFER_INFO ConsoleScreenBufferInfo;
    COORD dwWriteCoord;
    DWORD NumberOfCharsWritten;

    std::wcout << s << '\n';

    hStdOut = GetStdHandle(STD_OUTPUT_HANDLE);
    GetConsoleScreenBufferInfo(hStdOut, &ConsoleScreenBufferInfo);
    dwWriteCoord = ConsoleScreenBufferInfo.dwCursorPosition;
    dwWriteCoord.X += wcslen(s);
    for (int i = 0; i < wcslen(s); ++i) {
        --dwWriteCoord.X;
        WriteConsoleOutputCharacter(hStdOut, s+i, 1, dwWriteCoord, &NumberOfCharsWritten);
        }

    return 0;
}

LPNumberOfCharsWrited[输出] 指向接收实际写入字符数的变量的指针

int main()
{
    HANDLE hStdOut;
    wchar_t s[] = L"reverse";
    CONSOLE_SCREEN_BUFFER_INFO ConsoleScreenBufferInfo;
    COORD dwWriteCoord;
    DWORD NumberOfCharsWritten;

    std::wcout << s << '\n';

    hStdOut = GetStdHandle(STD_OUTPUT_HANDLE);
    GetConsoleScreenBufferInfo(hStdOut, &ConsoleScreenBufferInfo);
    dwWriteCoord = ConsoleScreenBufferInfo.dwCursorPosition;
    dwWriteCoord.X += wcslen(s);
    for (int i = 0; i < wcslen(s); ++i) {
        --dwWriteCoord.X;
        WriteConsoleOutputCharacter(hStdOut, s+i, 1, dwWriteCoord, &NumberOfCharsWritten);
        }

    return 0;
}

我一点也不明白。我只需要将所选的键写入缓冲区，然后打印出来。 我卡住了

int main()
{
    HANDLE hStdOut;
    wchar_t s[] = L"reverse";
    CONSOLE_SCREEN_BUFFER_INFO ConsoleScreenBufferInfo;
    COORD dwWriteCoord;
    DWORD NumberOfCharsWritten;

    std::wcout << s << '\n';

    hStdOut = GetStdHandle(STD_OUTPUT_HANDLE);
    GetConsoleScreenBufferInfo(hStdOut, &ConsoleScreenBufferInfo);
    dwWriteCoord = ConsoleScreenBufferInfo.dwCursorPosition;
    dwWriteCoord.X += wcslen(s);
    for (int i = 0; i < wcslen(s); ++i) {
        --dwWriteCoord.X;
        WriteConsoleOutputCharacter(hStdOut, s+i, 1, dwWriteCoord, &NumberOfCharsWritten);
        }

    return 0;
}

谢谢你的回答。 //编辑

int main()
{
    HANDLE hStdOut;
    wchar_t s[] = L"reverse";
    CONSOLE_SCREEN_BUFFER_INFO ConsoleScreenBufferInfo;
    COORD dwWriteCoord;
    DWORD NumberOfCharsWritten;

    std::wcout << s << '\n';

    hStdOut = GetStdHandle(STD_OUTPUT_HANDLE);
    GetConsoleScreenBufferInfo(hStdOut, &ConsoleScreenBufferInfo);
    dwWriteCoord = ConsoleScreenBufferInfo.dwCursorPosition;
    dwWriteCoord.X += wcslen(s);
    for (int i = 0; i < wcslen(s); ++i) {
        --dwWriteCoord.X;
        WriteConsoleOutputCharacter(hStdOut, s+i, 1, dwWriteCoord, &NumberOfCharsWritten);
        }

    return 0;
}

有了你的两个答案，我终于离开了，谢谢你抽出时间

int main()
{
    HANDLE hStdOut;
    wchar_t s[] = L"reverse";
    CONSOLE_SCREEN_BUFFER_INFO ConsoleScreenBufferInfo;
    COORD dwWriteCoord;
    DWORD NumberOfCharsWritten;

    std::wcout << s << '\n';

    hStdOut = GetStdHandle(STD_OUTPUT_HANDLE);
    GetConsoleScreenBufferInfo(hStdOut, &ConsoleScreenBufferInfo);
    dwWriteCoord = ConsoleScreenBufferInfo.dwCursorPosition;
    dwWriteCoord.X += wcslen(s);
    for (int i = 0; i < wcslen(s); ++i) {
        --dwWriteCoord.X;
        WriteConsoleOutputCharacter(hStdOut, s+i, 1, dwWriteCoord, &NumberOfCharsWritten);
        }

    return 0;
}

但我现在无法将特定密钥打印到控制台

int main()
{
    HANDLE hStdOut;
    wchar_t s[] = L"reverse";
    CONSOLE_SCREEN_BUFFER_INFO ConsoleScreenBufferInfo;
    COORD dwWriteCoord;
    DWORD NumberOfCharsWritten;

    std::wcout << s << '\n';

    hStdOut = GetStdHandle(STD_OUTPUT_HANDLE);
    GetConsoleScreenBufferInfo(hStdOut, &ConsoleScreenBufferInfo);
    dwWriteCoord = ConsoleScreenBufferInfo.dwCursorPosition;
    dwWriteCoord.X += wcslen(s);
    for (int i = 0; i < wcslen(s); ++i) {
        --dwWriteCoord.X;
        WriteConsoleOutputCharacter(hStdOut, s+i, 1, dwWriteCoord, &NumberOfCharsWritten);
        }

    return 0;
}

**

int main()
{
    HANDLE hStdOut;
    wchar_t s[] = L"reverse";
    CONSOLE_SCREEN_BUFFER_INFO ConsoleScreenBufferInfo;
    COORD dwWriteCoord;
    DWORD NumberOfCharsWritten;

    std::wcout << s << '\n';

    hStdOut = GetStdHandle(STD_OUTPUT_HANDLE);
    GetConsoleScreenBufferInfo(hStdOut, &ConsoleScreenBufferInfo);
    dwWriteCoord = ConsoleScreenBufferInfo.dwCursorPosition;
    dwWriteCoord.X += wcslen(s);
    for (int i = 0; i < wcslen(s); ++i) {
        --dwWriteCoord.X;
        WriteConsoleOutputCharacter(hStdOut, s+i, 1, dwWriteCoord, &NumberOfCharsWritten);
        }

    return 0;
}

while（counter++让我们复制文档以供参考

BOOL WINAPI WriteConsole(
  _In_             HANDLE  hConsoleOutput,
  _In_       const VOID    *lpBuffer,
  _In_             DWORD   nNumberOfCharsToWrite,
  _Out_            LPDWORD lpNumberOfCharsWritten,
  _Reserved_       LPVOID  lpReserved
);

int main()
{
    HANDLE hStdOut;
    wchar_t s[] = L"reverse";
    CONSOLE_SCREEN_BUFFER_INFO ConsoleScreenBufferInfo;
    COORD dwWriteCoord;
    DWORD NumberOfCharsWritten;

    std::wcout << s << '\n';

    hStdOut = GetStdHandle(STD_OUTPUT_HANDLE);
    GetConsoleScreenBufferInfo(hStdOut, &ConsoleScreenBufferInfo);
    dwWriteCoord = ConsoleScreenBufferInfo.dwCursorPosition;
    dwWriteCoord.X += wcslen(s);
    for (int i = 0; i < wcslen(s); ++i) {
        --dwWriteCoord.X;
        WriteConsoleOutputCharacter(hStdOut, s+i, 1, dwWriteCoord, &NumberOfCharsWritten);
        }

    return 0;
}

LPNumberOfChars写入[输出]指向接收
实际写入的字符数

int main()
{
    HANDLE hStdOut;
    wchar_t s[] = L"reverse";
    CONSOLE_SCREEN_BUFFER_INFO ConsoleScreenBufferInfo;
    COORD dwWriteCoord;
    DWORD NumberOfCharsWritten;

    std::wcout << s << '\n';

    hStdOut = GetStdHandle(STD_OUTPUT_HANDLE);
    GetConsoleScreenBufferInfo(hStdOut, &ConsoleScreenBufferInfo);
    dwWriteCoord = ConsoleScreenBufferInfo.dwCursorPosition;
    dwWriteCoord.X += wcslen(s);
    for (int i = 0; i < wcslen(s); ++i) {
        --dwWriteCoord.X;
        WriteConsoleOutputCharacter(hStdOut, s+i, 1, dwWriteCoord, &NumberOfCharsWritten);
        }

    return 0;
}

所以我们知道第四个参数必须是指向变量的指针。什么类型的变量？指针是
LPDWORD
。在微软，LP-X

是指向X的指针，因此

LPDWORD

是

DWORD*

。而

DWORD

是一些未指定的32位类型。可能是

std:：unit32\t

，也可能是

unsigned long

。你不必在意

int main()
{
    HANDLE hStdOut;
    wchar_t s[] = L"reverse";
    CONSOLE_SCREEN_BUFFER_INFO ConsoleScreenBufferInfo;
    COORD dwWriteCoord;
    DWORD NumberOfCharsWritten;

    std::wcout << s << '\n';

    hStdOut = GetStdHandle(STD_OUTPUT_HANDLE);
    GetConsoleScreenBufferInfo(hStdOut, &ConsoleScreenBufferInfo);
    dwWriteCoord = ConsoleScreenBufferInfo.dwCursorPosition;
    dwWriteCoord.X += wcslen(s);
    for (int i = 0; i < wcslen(s); ++i) {
        --dwWriteCoord.X;
        WriteConsoleOutputCharacter(hStdOut, s+i, 1, dwWriteCoord, &NumberOfCharsWritten);
        }

    return 0;
}

任一种方式，您应该知道C++足够好，知道<代码>和>代码>是地址运算符，所以<代码>变量>代码>是指向“代码>变量的指针。

< P>下面将写一个反向字符串。因此它是Wrand EndoSeOutPutter字符函数的一个例子。它得到当前的光标位置，然后用T来推进X值。输入字符串的长度，然后写出每个字符，从第一个字符开始，并递减每个字符的光标位置

int main()
{
    HANDLE hStdOut;
    wchar_t s[] = L"reverse";
    CONSOLE_SCREEN_BUFFER_INFO ConsoleScreenBufferInfo;
    COORD dwWriteCoord;
    DWORD NumberOfCharsWritten;

    std::wcout << s << '\n';

    hStdOut = GetStdHandle(STD_OUTPUT_HANDLE);
    GetConsoleScreenBufferInfo(hStdOut, &ConsoleScreenBufferInfo);
    dwWriteCoord = ConsoleScreenBufferInfo.dwCursorPosition;
    dwWriteCoord.X += wcslen(s);
    for (int i = 0; i < wcslen(s); ++i) {
        --dwWriteCoord.X;
        WriteConsoleOutputCharacter(hStdOut, s+i, 1, dwWriteCoord, &NumberOfCharsWritten);
        }

    return 0;
}
