Process Problem

[N3messys]

Hi all,I'm new to CodeGuru,I'm Romanian and I can't speech very good english.I'm using Visual C++ Professional, and CLR.I'm still learning C++.My project is a Server Manager (for HLDS).I'm trying to set "hlds.exe" process to HIGH priority,but first,I check if the process is active.Problem : My function allways return false and I can't see the mistake.
Function :

bool HLDSIsRunning()
{    
unsigned long aProcesses[1024], cbNeeded, cProcesses;
if(EnumProcesses(aProcesses, sizeof(aProcesses), &cbNeeded) == 0)
return false;

cProcesses = cbNeeded / sizeof(unsigned long);
for(unsigned int i = 0; i < cProcesses; i++)
		{
			if(aProcesses[i] == 0)
			continue;

		HANDLE hProcess = OpenProcess(PROCESS_QUERY_INFORMATION | PROCESS_VM_READ, 0, aProcesses[i]);
		TCHAR buffer[50];
		GetModuleBaseName(hProcess, 0, buffer, 50);
		DWORD dwExitStatus = 0;
		GetExitCodeProcess(hProcess, &dwExitStatus);
		CloseHandle(hProcess);
		if( buffer == _T("hlds.exe") && dwExitStatus != 0 )	return true;
		}
return false;
}

All Code :

#include <windows.h>
#include <Psapi.h>
#include <tchar.h>

#pragma comment(lib,"Winmm.lib")
#pragma comment(lib,"Psapi.lib")

#pragma once

HANDLE popcorn;

bool HLDSIsRunning()
{    
unsigned long aProcesses[1024], cbNeeded, cProcesses;
if(EnumProcesses(aProcesses, sizeof(aProcesses), &cbNeeded) == 0)
return false;

cProcesses = cbNeeded / sizeof(unsigned long);
for(unsigned int i = 0; i < cProcesses; i++)
		{
			if(aProcesses[i] == 0)
			continue;

		HANDLE hProcess = OpenProcess(PROCESS_QUERY_INFORMATION | PROCESS_VM_READ, 0, aProcesses[i]);
		TCHAR buffer[50];
		GetModuleBaseName(hProcess, 0, buffer, 50);
		DWORD dwExitStatus = 0;
		GetExitCodeProcess(hProcess, &dwExitStatus);
		CloseHandle(hProcess);
		if( buffer == _T("hlds.exe") && dwExitStatus != 0 )	return true;
		}
return false;
}
