程序创建进程时钩子注入成功 直接打开注入成功但是不执行,该怎么解决

程序创建进程时钩子注入成功 直接打开注入成功但是不执行
STARTUPINFOA si={0};

执行if分支 创建目标进程 注入钩子成功 执行没有问题
但是else分支 我先打开要注入的目标 然后注入钩子 注入成功但是执行不了
请问哪里出了问题

------解决方案--------------------
难道是权限问题，用CreateProcess是子进程的缘故？OpenXX，FindXX等函数的返回值都判断过了吗
------解决方案--------------------
HookDx.dll路径对不对
------解决方案--------------------

C/C++ code

LPVOID pMem = VirtualAllocEx(hProcess,NULL,MAX_PATH,MEM_COMMIT,PAGE_EXECUTE_READWRITE);
