Shell execute issue

Can anyone tell me why is this code not working ?

It’s in a button, but when I click, nothing happens…

dim IXBShell as New Shell
IXBShell.Mode = 2
IXBShell.Execute (chr(34)+“D:\HasarFormAR\IxBatch\ixbatchw.exe -p COM2 -i FacturaA.txt -o out.txt -s 9600 -t”+chr(34))

If I type the line in a shell window it works…
Also tried with “writeline” instead of execute… but nothing…
what am i doing wrong ?
Thanks!

Ready ! I got it to work…

The IXBShell.Execute line was lacking the patch to “FacturaA.txt” AND the chr(34) were not needed.
