How to get the PID on WINNT & WIN2000

[labnotes]

Using PERL I can run pulist.exe and step through each line using with Win32:rocess loaded. I am using Bloodshed dev-C++ ver.4.9.8.0. Can I do the same with a
C++ function?

See the API documentation for EnumProcesses() in the Platform SDK. Here is an MSDN Article that discusses how to do it:

'EnumProcesses' could be used, but isn't too helpful as cannot link process names to there appropriate PID's. You can use a ToolHelp function, like in the program below (just lists all process names and there PID's):

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

int WINAPI WinMain(HINSTANCE, HINSTANCE, LPSTR, int)
{
  HANDLE hconsoleInput, hconsoleOutput;
  char string[100];
  DWORD written;
  HANDLE hSnapShot;
  PROCESSENTRY32 ProcEntry;
  BOOL hRes;

  AllocConsole();
  hconsoleOutput = GetStdHandle(STD_OUTPUT_HANDLE);
  hconsoleInput  = GetStdHandle(STD_INPUT_HANDLE);
	
  hSnapShot=CreateToolhelp32Snapshot(TH32CS_SNAPALL, NULL);
  ProcEntry.dwSize = sizeof(ProcEntry);
  Process32First(hSnapShot, &ProcEntry);
  while(1)
  {
    hRes = Process32Next (hSnapShot, &ProcEntry);
    if (hRes == FALSE)
	break;
    sprintf(string,&quot;  %s %x\n&quot;,ProcEntry.szExeFile, ProcEntry.th32ProcessID);
    WriteConsole(hconsoleOutput,string,strlen(string),&written,0);
  }
  ReadConsole(hconsoleInput,string,1,&written,0);
  return (0);
}

Hope that is useful.

Hi

The above code doesn't work on a Win NT machine I tried using the
EnumProcesses() function but I run into a road block with __leave and I don't
understand the information I found on

http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dndeepc/html/deep060399.asp.

any ideas Thanks

Brin

NT What version? Your first post does not even indicate NT as a constraint let alone what version. If you have specific constraints for your solution you surely need to provide them in your post right? Otherwise how is anyone out here supposed to know about it, magic?

Sorry but I just don’t understand that. It seems that whatever you replaced with the [red]……[/red] might be needed to complete that statement.

You are correct sorry windows NT 4 Sp6. The "__leave" is part of the code on the
MSDN web site.
