[Gambas-user] hProcess is NULL

[Demosthenes Koptsis]

if i use

SHELL sCommand to sVar

i have to wait to complete execution of command. Right?

In my case 
hProcess1 = SHELL sCommand FOR INPUT AS "AntiVirRun"

sCommand is a scan command of an antivirus for 9000 files and more...

This takes almost 10 minutes or more to be completed.

i want in these 10 minutes to read the stdout from this sCommand because
i get messages for each file if it is cleaned or has a virus.

if i used
hProcess1 = SHELL sCommand WAIT FOR INPUT AS "AntiVirRun"

it wont work, i cant process AntiVirRun_Read

the same is for
SHELL sCommand to sVar.

So i wanted a way to stop executiono program for the time the sCommand
is executed and also to process AntiVirRun_Read

this is worked with

 hProcess1 = SHELL sCommand FOR INPUT AS "AntiVirRun"
 WHILE (hProcess1.Running)
  WAIT 10
 WEND
