DLL Injection problem

See more:

C++

Good Afternoon

I'm trying to inject a DLL into a process but when the dll is injected the code isn't run

DLL code

 #ifndef _DLLTEST_H_
 #define _DLLTEST_H_

 #include <stdio.h>
 #include <windows.h>
#include <stdlib.h>

 extern "C" __declspec(dllexport) void NumberList();


 #endif

The rest of the dll code

#include "dlltest.h"
 #define MAXMODULE 50

 char module[MAXMODULE];


 extern "C" __declspec(dllexport)

 void NumberList() 
 {
	 FILE *f=fopen("C:\\asd.txt","w");
     
 }

DLL created with Visual C++ 2010


DLL injector code

unsigned long GetTargetProcessIdFromProcname(char *procName)
{
   PROCESSENTRY32 pe;
   HANDLE thSnapshot;
   BOOL retval, ProcFound = 0;

   thSnapshot = CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS, 0);

   if(thSnapshot == INVALID_HANDLE_VALUE)
   {
      puts("Erro");
      return 0;
   }

   pe.dwSize = sizeof(PROCESSENTRY32);

    retval = Process32First(thSnapshot, &pe);

   while(retval)
   {
      if(strstr(pe.szExeFile, procName) )
      {
         ProcFound = 1;
         break;
      }

      retval    = Process32Next(thSnapshot,&pe);
      pe.dwSize = sizeof(PROCESSENTRY32);
  }

   return pe.th32ProcessID;
}
main()
{
	unsigned long id;
	DWORD *pid;
	HANDLE hd;
	LPVOID gp,rs;
	
	gp=(LPVOID)GetProcAddress(GetModuleHandle("kernel32.dll"), "LoadLibraryA");

	id=GetTargetProcessIdFromProcname(PROCESS_NAME);

	hd=OpenProcess(PROCESS_ALL_ACCESS, FALSE, id);

	rs=(LPVOID)VirtualAllocEx(hd, NULL, strlen(DLL_NAME), MEM_RESERVE|MEM_COMMIT, PAGE_READWRITE);

	if(!WriteProcessMemory(hd, (LPVOID)rs, DLL_NAME, strlen(DLL_NAME), NULL))
	puts("error 1");
	if(!CreateRemoteThread(hd, NULL, 0, (LPTHREAD_START_ROUTINE)gp, (LPVOID)rs, 0, NULL))
		puts("error 2");

	system("pause");

}
