This is concerning Windows XP processes.
I have a process running, let\'s call it Process1. Process1 creates a new process, Process2, and saves its id.
Now,
I found this today, it is from 2003. It finds a process by name, you don't even need the pid.
\#include windows.h
\#include tlhelp32.h
\#include iostream.h
int FIND_PROC_BY_NAME(const char *);
int main(int argc, char *argv[])
{
// Check whether a process is currently running, or not
char szName[100]="notepad.exe"; // Name of process to find
int isRunning;
isRunning=FIND_PROC_BY_NAME(szName);
// Note: isRunning=0 means process not found, =1 means yes, it is found in memor
return isRunning;
}
int FIND_PROC_BY_NAME(const char *szToFind)

// Please report any problems or bugs to kochhar@physiology.wisc.edu
// The latest version of this routine can be found at:
// http://www.neurophys.wisc.edu/ravi/software/killproc/
// Check whether the process "szToFind" is currently running in memory
// This works for Win/95/98/ME and also Win/NT/2000/XP
// The process name is case-insensitive, i.e. "notepad.exe" and "NOTEPAD.EXE"
// will both work (for szToFind)
// Return codes are as follows:
// 0 = Process was not found
// 1 = Process was found
// 605 = Unable to search for process
// 606 = Unable to identify system type
// 607 = Unsupported OS
// 632 = Process name is invalid
// Change history:
// 3/10/2002 - Fixed memory leak in some cases (hSnapShot and
// and hSnapShotm were not being closed sometimes)
// 6/13/2003 - Removed iFound (was not being used, as pointed out
// by John Emmas)
