【求助】shellcode怎么写到一个dll链接库文件
我想将一段shellcode写进一个用C编写的一个项目，shellcode可以单独编译并运行，可我一旦写到那个dll的项目，就运行不起来了这是那个dll的项目：https://github.com/BitCrackers/AmongUsMenu.git
这是我的shellcode:
------------------------------------------------------------------------
#include <stdio.h>
#include <windows.h>
#pragma comment(linker,"/subsystem:\"windows\" /entry:\"mainCRTStartup\"")// 隐藏控制台窗口显示
#pragma comment(linker,"/INCREMENTAL:NO") // 减小编译体积
#pragma comment(linker, "/section:.data,RWE")
//#include<stdio.h>
//#include<windows.h>
//#pragma comment( linker, "/subsystem:\"windows\" /entry:\"mainCRTStartup\"")

cpp最简的代码没有问题，估计是你的shellcode出问题了。
上面一堆shellcode hex不好调试，先检查一下栈平衡
