how to get PID by name in c++ code example

Example: how to get PID by name in c++

#include <Windows.h>
#include <iostream>
#include <Tlhelp32.h>
#include <comdef.h>

/*snapshot for all running processes*/
	HANDLE hSnapShot = CreateToolhelp32Snapshot(TH32CS_SNAPALL, NULL);
	PROCESSENTRY32 pEntry;
	/*initializing size - needed for using Process32First*/
	pEntry.dwSize = sizeof(pEntry);
	BOOL hRes = Process32First(hSnapShot, &pEntry);
	/*while first process in pEntry exists*/
	while (hRes)
	{
		/*create const char for string comparison*/
		_bstr_t b(pEntry.szExeFile);
		if (strcmp(b, "process name") == 0)
		{
			std::cout << (DWORD)pEntry.th32ProcessID;
			break;
		}
		hRes = Process32Next(hSnapShot, &pEntry);
	}
