Hi. Really liked the lib. Can I get a bit more documentation, specially on ExternalDisplaySMM. Great job

"Display" doesnt need to Initialize?

"Display" doesnt need to Initialize?

Please check the attached sample

 

[Andy Leung]

I saw o the #1 post, the description of Display, the "Functions" only has : IsInitialized ,buy no 'Initialize'. I tried:
Dim aa as Display
Dim s as string
s=aa.Name

But the compile said aa is not initialized. Anything I missed?

Display is a service , in the sample I just start it.
