一次难忘的项目经历

遍历所有进程(exe) 代码(C++)

本文地址: http://blog.csdn.net/caroline_wendy/article/details/29381987

遍历所有进程, 即任务管理器中所有的进程目录, 包含名称和进程ID.

返回字典: Key: 进程名字, Value: 进程ID.

代码:

/*
 * main.cpp

/*vs 2012*/

#include <iostream>
#include <string>
#include <map>

#include <windows.h>
#include <TlHelp32.h>

using namespace std;

bool traverseProcesses(std::map<std::string, int>& _nameID)
{
	PROCESSENTRY32 pe32;
	pe32.dwSize = sizeof(pe32);

	HANDLE hProcessSnap = CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS, 0);
	if(hProcessSnap == INVALID_HANDLE_VALUE) {
		std::cout << "CreateToolhelp32Snapshot Error!" << std::endl;;
		return false;
	}

	BOOL bResult =Process32First(hProcessSnap, &pe32);

	int num(0);

	while(bResult)
	{
		std::string name = pe32.szExeFile;
		int id = pe32.th32ProcessID;

		std::cout << "[" << ++num << "] : " <<"Process Name:"
			<< name << "  " << "ProcessID:" << id<< std::endl;

		_nameID.insert(std::pair<string, int>(name, id)); //字典存储
		bResult = Process32Next(hProcessSnap,&pe32);
	}

	CloseHandle(hProcessSnap);

	return true;
}

int main()
{
	std::map<std::string, int> _nameID;

	if (!traverseProcesses(_nameID)) {
		cout << "Start Process Error!" << endl;
	}

	return 0;
}
