using wshell.exec causes lockup while reading the output - what to do ?

Show all headers | View raw

Hello all

I'm running a console-based windows program, and need to capture its output. 
When I try to use the "exec" method than, nomatter what I try, something 
locks up.

My code is basically this:

Set oExec = WshShell.Exec(sCmd)
Do While oExec.Status = 0
     WScript.Sleep 100
     wscript.echo oExec.stdout.readall
Loop

As the program also outputs on stderr I've changed the above reading of 
stdout with

if not oExec.stdout.atendofstream then wscript.echo oExec.stdout.read(1000)
if not oExec.stderr.atendofstream then wscript.echo oExec.stderr.read(1000)

But no matter what I've tried (small buffers, large buffers), at some point 
in the output it locks up. :-(

Apart from switching to the "run" method*, what can I do ?

*I've got the "run" method working.  But the output capturing needs the use 
of "cmd /e ", which in turn causes my screen to go black a few times 
(mutiple calls) with no (progress) output on it.  Not nice.

Regards,
Rudy Wieser
