这段DLL注入的代码哪儿有问题，求解（高分求）。

C/C++ code

#include <windows.h> #include <iostream>#include <cstdio>using namespace std;BOOL WINAPI LoadLib(DWORD dwProcessId, LPWSTR lpszLibName) {     HANDLE hProcess = NULL,     hThread = NULL;     LPWSTR lpszRemoteFile = NULL;     hProcess = OpenProcess(PROCESS_CREATE_THREAD | PROCESS_VM_OPERATION | PROCESS_VM_WRITE,FALSE,dwProcessId);     if (hProcess == NULL)     {         return FALSE;     }     lpszRemoteFile = (LPWSTR)VirtualAllocEx(hProcess, NULL, sizeof(WCHAR) * lstrlenW(lpszLibName) + 1, MEM_COMMIT, PAGE_READWRITE);     if (lpszRemoteFile == NULL)     {         return FALSE;     }     if (!WriteProcessMemory(hProcess,lpszRemoteFile,(PVOID)lpszLibName, sizeof(WCHAR) * lstrlenW(lpszLibName) + 1,NULL))     {         return FALSE;     }     FARPROC pfnThreadRtn = (FARPROC)GetProcAddress(GetModuleHandle("Kernel32.dll"),"LoadLibraryW");     if (pfnThreadRtn == NULL)     {         return FALSE;     }     hThread = CreateRemoteThread(hProcess,NULL,0,(LPTHREAD_START_ROUTINE)pfnThreadRtn,lpszRemoteFile,0,NULL);     if (hThread == NULL)     {         return FALSE;     }     WaitForSingleObject(hThread, INFINITE);     VirtualFreeEx(hProcess, lpszRemoteFile, 0, MEM_RELEASE);     CloseHandle(hThread);     CloseHandle(hProcess);        return TRUE; } int main(int argc,char* argv[]){     if(LoadLib(1836,(LPWSTR)"dll.dll") == FALSE)    {        cout << "注入失败" << endl;        }    else     {        cout << "注入成功" << endl;            }    system("pause");    return 0; }

能够运行，函数也返回TRUE，但是注入的进程没有任何反应，1836是我电脑上explorer.exe的当前PID
dlld.dll中的代码如下

C/C++ code

BOOL APIENTRY DllMain( HANDLE hModule,                        DWORD  ul_reason_for_call,                        LPVOID lpReserved                     ){    switch (ul_reason_for_call)    {    case DLL_PROCESS_ATTACH:        MessageBox(NULL,"已经注入","Message",MB_OK);        break;    case DLL_PROCESS_DETACH:        MessageBox(NULL,"已经注销","Message",MB_OK);        break;    }    return TRUE;}

求大牛不吝指点，感激不尽。

[解决办法]
用procexp查看dll是否装载了
