win864位操作系统下VirtualAllocEx失败 GetLastError返回拒绝访问

c++/mfc   win8下求指教

LPVOID baseAddr=::VirtualAllocEx(hProcess,NULL,1024*4,MEM_COMMIT|MEM_RESERVE,PAGE_EXECUTE_READWRITE);

已经提权了，OpenProcess是成功的

HANDLE hProcess=OpenProcess(PROCESS_CREATE_THREAD,FALSE,dwID);

2 个解决方案

#1

NEED PROCESS_VM_OPERATION 
NOT CREATE

#2

额，谢谢啊，居然没有注意到
