[Gambas-user] progress bar and shell command which takes ages

[lozza1978]

Hi there,

Thanks for your reply,
I have tried the following code but im still not sure how to implement the
progress bar, please bare with me while i try and explain the issues im
having.

When the user clicks the button, it launches 

StartTheProcess()

this then updates the progress bar to

ProgressBar1.Value= "0.2"

But the progress bar never updates anymore (stays at 2%) and im wondering if
the EXEC is actually still running the command?

hProc=Exec[Application,param1,param2...] FOR INPUT 
Object.Attach(hProc,Me,"hProc") 

Should the Progress bar update while the EXEC command is still running?

Thanks so much for your help.
