Process Problem
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 :
Code:
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 :
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;
}

Re: Process Problem
Code:
buffer == _T("hlds.exe")
You are comparing the pointers, not the text itself.
