Thread: process ID´s

Platform SDK (search on google "microsoft platform sdk", first result):

Can't tell you anything about getting process ID's though. This probably belongs on the Windows forum.

Easy... Here's how to get all running processes info. You'll need:

• struct PROCESSENTRY32
• BOOL WINAPI Process32First(HANDLE hSnapshot,LPPROCESSENTRY32 lppe);
• BOOL WINAPI Process32Next(HANDLE hSnapshot,LPPROCESSENTRY32 lppe);

Code:

#include <iostream>
#include <windows.h>
#include <tlhelp32.h>

BOOL ListProcesses(){	
	HANDLE hSnapshot;
	PROCESSENTRY32 process;

	hSnapshot=CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS|TH32CS_SNAPTHREAD, 0);//2nd parameter ignored
	if(hSnapshot==INVALID_HANDLE_VALUE) return FALSE;

	ZeroMemory(&process, sizeof(PROCESSENTRY32));
	process.dwSize=sizeof(PROCESSENTRY32);

	if(!Process32First(hSnapshot, &process))
		return FALSE;

	do{
		std::cout<<process.szExeFile<<"\tPID: "<<process.th32ProcessID<<std::endl;
	}while(Process32Next(hSnapshot, &process));
	
	CloseHandle(hSnapshot);

	return TRUE;
}

int main(){
	std::cout<<"Listing processes\n";
	ListProcesses();
	std::cin.get();
	return 0;
}

Now adapt this code to your needs.
NOTE the 32 in the types names. That referes to 32-bit processes. Later with 64-bit CPU we'll use 64, for 64 bit processes, and 32 for 32 bit processes running on 64 bit machine, although emulated.

That link shows code for listing all the processes (That code gives process name, like explorer.exe and also gives process ID of each one). My suggestion is make a simple class to hold process name, PID, and handle. Then make a list of that class, and instead of printing them to the screen, insert them into a list, then you have a list you can search through processes and such. I have just recently done this, if you want any help, IM or email me.
