how to deal with app.runtime ? Trying to make pictureframe nod

but i wonder where to find sintaxis of this app.runtime

Now it looks like this:

If Activate Then     

app.RunScript("_PictureFrame "" vertical "" selfillumination = " & I & " Embedbitmap = " & E & " Autoname = " & N & " _Enter")
 

End If

but

1)  need to input 2 points somehow

2) it wrote "app. is not defined" in "out"

Where can i find examples of correct sintaxis of app.Runtimes?
