Re: how can I list all the processes in the system

I have writen some codes as follow???

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

// Forward declarations:

BOOL GetProcessList( );
BOOL ListProcessModules( DWORD dwPID );
BOOL KillProcessFromName(LPCTSTR name);
void printError( TCHAR* msg );

//
void main( )
{
  GetProcessList( );
}

//??????????????????

  if( hProcessSnap == INVALID_HANDLE_VALUE )
  {

    return( FALSE );
  }

  // Set the size of the structure before using it.
  pe32.dwSize = sizeof( PROCESSENTRY32 );

  // Retrieve information about the first process,
  // and exit if unsuccessful
  if( !Process32First( hProcessSnap, &pe32 ) )

object!
    return( FALSE );
  }

  // Now walk the snapshot of processes, and
  // display information about each process in turn
  do
  {

  // Display the message
  printf( "\n WARNING: %s failed with error %d (%s)", msg, eNum,

}

I can get some processes' location,but I can't get all,such as
svchost.
How can I get all processes' location?

Thank you!
