Hi Stewart, has the use of the ExternalProcessStreams resolved your issue ?
I have been using ExternalProcessStreams albeit the earlier version (prior to it using threaded call out) and customers sporadically also receive the same error i.e. 127 Pipe creation failed. I'll see if updating to the latest makes any difference cheers Denis On 2/28/07, Stewart MacLean <[hidden email]> wrote: > Thanks Michael, > > I'll check it out... > > Cheers, > > Stewart > > >-----Original Message----- > >From: Michael Lucas-Smith [mailto:michael.lucas- > >[hidden email]] > >Sent: 27 February 2007 6:56 p.m. > >To: Stewart MacLean > >Cc: [hidden email] > >Subject: Re: [VW 7.4.0] Intermittent error using WinProcess>>cshOne: > "Pipe > >creation has failed.

Hi Denis,
I downloaded ExternalProcessStreams and had a brief look. As it required SUnit and some other stuff as prerequisites, and that the problem hasn't occurred for sometime, I haven't taken the time to reimplement using this. (If it ain't broke...). As you are also getting this error using ExternalProcessStreams, I suspect that this one of Windows little mysteries...
