Maps, GPS and Annotations with PowerServer Mobile


Hello,

since the old days of Appeon Mobile, now PowerServer Mobile, the possibility to write PowerScript and deploy a mobile apps to iOS and Android devices has been a great plus to PowerBuilder developers.

Getting PowerFilter to work with Powerserver Web


In order to use PowerFilter in Powerserver Web you need to change 3 things to work around appeon problems.        

1) Structure comment
