Inject use python/c++ hat ein anderes Ergebnis ⇐ C++

Ich verwende die Python-Inject-DLL in eine dritte Software, um einen ersetzten Text zu erhalten, aber ich bekomme einen chaotischen Chaotischen Code

hook.cpp

#include

#include  // 用于 strncpy

HHOOK g_hHook = NULL;

// 辅助函数：窄字符串(std::string) 转 宽字符串(std::wstring)（适配系统默认编码）

// 获取转换所需的宽字符长度（CP_ACP=系统默认ANSI编码）
int wideLen = MultiByteToWideChar(CP_ACP, 0, str.c_str(), -1, NULL, 0);
