獲取進程列表、進程命令行、結束進程

<span style="font-size:14px;"><span style="font-size:12px;">CString MyGetProcess()
{
	CString csTemp = "", csPid;
	HANDLE hSnapshot, mehandle;
	
	hSnapshot = CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS, 0);

	PROCESSENTRY32 pe;
	MODULEENTRY32 me;

	pe.dwSize = sizeof(PROCESSENTRY32);

	Process32First(hSnapshot, &pe);
	
	do
	{
		mehandle = CreateToolhelp32Snapshot(TH32CS_SNAPMODULE, pe.th32ProcessID);

		me.dwSize = sizeof(MODULEENTRY32);

		Module32First(mehandle, &me);

		csPid.Format("%d", pe.th32ProcessID);

		if (pe.th32ProcessID == 0)
		{
			csTemp = csTemp + pe.szExeFile + "/t" + csPid + "/tSystem" + "/r/n" ;
		}
		else
		{
			csTemp = csTemp + pe.szExeFile + "/t" + csPid + "/t" + me.szExePath + "/r/n" ;
		}

		CloseHandle(mehandle);

	}while(Process32Next(hSnapshot, &pe));
	
	CloseHandle(hSnapshot);
	
	return csTemp;
}</span>

就是獲取進程的相關信息。

獲取特定進程命令行：第三個參數爲進程ID

<span style="font-size:14px;">TCHAR szPath[1024];
HANDLE hProcess;
hProcess = OpenProcess(PROCESS_ALL_ACCESS,FALSE,pe.th32ProcessID);
GetProcessCommandLine(hProcess, szPath, 1024)
</span>

<span style="font-size:14px;">//獲取進程命令行
BOOL GetProcessCommandLine(HANDLE hProcess, LPTSTR pszCmdLine, DWORD cchCmdLine)
{
	BOOL      bRet;
	DWORD      dwPos;
	LPBYTE      lpAddr;
	DWORD_PTR    dwRetLen;

	bRet = FALSE;

	dwPos = 0;
	lpAddr = (LPBYTE)GetCommandLine;
Win7:
	if(lpAddr[dwPos] == 0xeb && lpAddr[dwPos + 1] == 0x05)
	{
		dwPos += 2;
		dwPos += 5;
Win8:
		if(lpAddr[dwPos] == 0xff && lpAddr[dwPos + 1] == 0x25)
		{
			dwPos += 2;
			lpAddr = *(LPBYTE*)(lpAddr + dwPos);

			dwPos = 0;
			lpAddr = *(LPBYTE*)lpAddr;
WinXp:
			if(lpAddr[dwPos] == 0xa1)
			{
				dwPos += 1;
				lpAddr = *(LPBYTE*)(lpAddr + dwPos);
				bRet = ReadProcessMemory(hProcess,
					lpAddr,
					&lpAddr,
					sizeof(LPBYTE),
					&dwRetLen);
				if(bRet)
				{
					bRet = ReadProcessMemory(hProcess,
						lpAddr,
						pszCmdLine,
						cchCmdLine,
						&dwRetLen);
				}
			}
		}
		else
		{      
			goto WinXp;
		}
	}
	else
	{
		goto Win8;
	}
	return bRet;
}</span>

結束一個進程，在這裏要特別注意一個問題，hProcess = OpenProcess(PROCESS_ALL_ACCESS,FALSE,pe.th32ProcessID);第一個參數必須爲獲取所有權限，否則會出現結束進程失敗。這也是很容易犯的一個錯誤！

<span style="font-size:14px;"><span style="font-size:12px;">BOOL  nRes = TerminateProcess(hProcess, 999 );
int ierror=GetLastError();
if( nRes == 0 )
{
    MessageBox( _T("結束進程失敗！") );
}</span></span>
