无法将 char[9] 转换为 char*

Question

我是游戏黑客的新手，我是从学习教程开始的，该教程提供了源代码。了解它的作用后，我尝试编译，出现了 3 个相同的错误：

Can't convert char[9] to char* (Error n. C2664)

错误是指变量 ProcessName 和 ModuleName。

即使我有很好的 C++ 基础知识，我在使用指针时也总是遇到困难。

对错误感兴趣的函数是这两个：

bool AttachProcess(char *ProcessName) {
    HANDLE hPID = CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS, NULL);
    PROCESSENTRY32 procEntry;
    procEntry.dwSize = sizeof(procEntry);
    
    const WCHAR* procNameChar;
    int nChars = MultiByteToWideChar(CP_ACP, 0, ProcessName, -1, NULL, 0);
    procNameChar = new WCHAR[nChars];
    MultiByteToWideChar(CP_ACP, 0, ProcessName, -1, (LPWSTR)procNameChar, nChars);
    
    do
        if (!wcscmp(procEntry.szExeFile, procNameChar))
        {
            this->dwPID = procEntry.th32ProcessID;
            CloseHandle(hPID);
            this->hProcess = OpenProcess(PROCESS_ALL_ACCESS, FALSE, this->dwPID);
            return true;
        }
    while (Process32Next(hPID, &procEntry));
    
    CloseHandle(hPID);
    return false;
}
    
MODULEENTRY32 GetModule(char* ModuleName)
{
    HANDLE hModule = CreateToolhelp32Snapshot(TH32CS_SNAPMODULE, dwPID);
    MODULEENTRY32 mEntry;
    mEntry.dwSize = sizeof(mEntry);
    
    const WCHAR* modNameChar;
    int nChars = MultiByteToWideChar(CP_ACP, 0, ModuleName, -1, NULL, 0);
    modNameChar = new WCHAR[nChars];
    MultiByteToWideChar(CP_ACP, 0, ModuleName, -1, (LPWSTR)modNameChar, nChars);
    
    do
        if (!wcscmp(mEntry.szModule, modNameChar))
        {
            CloseHandle(hModule);
            return mEntry;
        }
    while (Module32Next(hModule, &mEntry));
    
    CloseHandle(hModule);
    mEntry.modBaseAddr = 0x0;
    return mEntry;
}

我在这里回忆那些功能：

MemoryManager()
{
    this->hProcess = NULL;
    this->dwPID = NULL;
    try {
        if (!AttachProcess("csgo.exe")) throw 1;
        this->ClientDLL = GetModule("client.dll");
        this->EngineDLL = GetModule("engine.dll");
        //and so on

Answer 1

我投了“csgo.exe”、“engine.dll”和“client.dll”：

if (!AttachProcess(const_cast<char*>("csgo.exe"))) throw 1;
        this->ClientDLL = GetModule(const_cast<char*>("client.dll"));
        this->EngineDLL = GetModule(const_cast<char*>("engine.dll"));

Answer 2

发生错误是因为您试图将字符串文字 (const char[]) 传递给需要指向非常量字符数组 (char *) 的指针的函数。

因为你从不修改ProcessName的内容你应该改变

bool AttachProcess(char *ProcessName)

到

//                 VVVVV
bool AttachProcess(const char *ProcessName)
