想hool掉Wsock32.dll的send函数的前5个字节，要改一直内存属性，但是失败!

之前我没有提权，需要提权吗？
求解！

用Error Lookup看下就知道了
内存分配访问无效。

BOOL VirtualProtect(
LPVOID lpAddress,
DWORD dwSize,
DWORD flNewProtect,
PDWORD lpflOldProtect );
lpAddress
Pointer to the base address of the region of pages whose access protection attributes are to be changed.
All pages in the specified region must have been allocated in a single call to the VirtualAlloc function. The pages cannot span adjacent regions that were allocated by separate calls to VirtualAlloc.

还可以#pragma comment(linker,"/section:.text,RW")
