[jeisma]

hi,

the op in this link pretty much describe what i need.

viewtopic.php?p=313299

however, i could not find execute command stage in my pallet.

any idea how to check if file exists, and rename afterwards before running the job runs?

The Execute Command activity is only in your Palette if a Sequence job is in focus in your Designer client. So you could do the check in the sequence that controls your job.

You could also use a before-job subroutine, but the only alternatives this gives you are to allow the job to run or to abort the job.

You can make an execute command routine in C++ to use in your parallel jobs for this sort of thing.

it is literally just this function:

Code: Select all

int wrapper(string s)
{
  system(s);
 //parse and return a value, 0 or 1 maybe, or the output of the system command
  return (something);
}

There are other ways. This one is just really simple.

thank you so much for the tips.

Under parallel job properties, on the General tab, the Before-job subroutine drop-down includes DSWaitForFile. I've not used it, but your manuals should have what you need to use it.
