Stream live output from background job?
hi.
i have small powershell application runs background job. used learning more powershell, please dont laugh much:) application built in powershell studio forms application running powershell. have function; "pinginfo" collects data. when i'm running background job dont output application console or log-files creating. if dont run function background job works well. can give me hint how stream live data backgroun job(function) textbox , logfile while job running? want way keep application window open (it preventing input if dont run job in backgroud). if need can post project-files screens , on. "non-working" script. non-working means not output data application window of log-files.

best regards thomas mortsell
you'll want @ runspaces this. here's article boe prox on subject
i'm not going to go through code posted here think this, if display initiating job can data when receives job. if job designed write data window should able it. see difference between 2 approaches?
hope helps! jason
