[Gambas-user] hProcess is NULL

[Demosthenes Koptsis]

Well i found a way


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

yes there is a reason because i want to stop execution of next lines but
i cant explain it right now.

So with this code i can process _Read event of process and stop
execution of code.

Anyway thank you all for the help.
