Connecting to a pid rather than to a process

Previously I was using TC 12 and C#

Connect.Sys["Process"]("java", 900000);
rootNode = driver.WaitProcess("java");

to connect to my Java process I start up. But lately there have been multiple instances of Java. For instance when this tries to run on the Jenkins machine, there is a Jenkins java process.

I am using C# so I was able to get the PID of the Java Process (integer) to which I would like to connect.

But I am not sure how to do this. I tried

Connect.Sys["Pid"](javapid, 90000);

where javapid is the pid, but it gave me an unknown name error. So does anyone have any suggestions?

And please don't tell me to use TestLeft.

(

driver.waitProcess(processName) just does a

return Connect.Sys["WaitProcess"](processName, timeout);

)

Thanks

I'm not sure to understand the need but perhaps this do your job ?

function GetMyPID(ProcessName, ProcessId) {
  var p = Sys.FindChild("ProcessName", ProcessName);
  var result = -1;
  while (p.Exists) {
    if (p.Id == ProcessId) {
      result = p.Id;
      break;
    } 
    p = Sys.FindChild("ProcessName", ProcessName);
  }
  return result;
}

  BenoitB Suggestion will work with one change. Replace "FindChild" with "FindAllChildren". FindChild will return only one process... and only the "top" one in the list. So, use "FindAllChildren" and loop through the array of found processes until the process object found has the same PID as the one you're looking for, then break.
  
  See documentation on FindAllChildren

    True, but i can affirm it will work as i've written, use it since a loong time.. (To terminate processs still executing with a certain PID).
    Lot of the underneath Window API manage themself the picking of next sibling when they are called in loop.

  Looks like that may do it

Man, it's been like half a year since I asked ;-) I figured out some other way but now I do not remember.

  Perhaps, once you find the solution, you could post it and mark it solved? That would avoid "resurrection" of dead topics like this. :-)

    Thanks everyone for participation:smileyhappy:
    
    Since this got ressurected I'll go ahead and mark BenoitB's answer as a solution for future reference.
