[David McFarlane]

Tobias,

The "AppActivate" topic in the E-Basic Help facility contains a 
complete code example.  I went ahead and pasted the complete example 
into good-old EP1 E-Run to test it out myself.  Sadly, it does not 
work.  First, it fails to declare its "id" variable.  Fixing that got 
me to a "Path/File access error".  Substituting "notepad.exe" for 
"clock.exe" then got me to a "Can't find window" error on the 
AppActivate line.  Using the id variable instead of a window name 
string there got me to a "Can't find window" error on the AppClose 
line.  Once again using the id variable instead of a window name 
string got me a fully working example.  So here is the fully working result:

Sub Main()
     dim id
     id = Shell("notepad.exe",1)
     AppActivate id
     Sleep(2000)
     AppClose id
End Sub

Of course, to test this in an E-Studio inline object (instead of EP1 
E-Run), you need to leave out the first and last lines (Sub Main(), End Sub).

And that is everything I know about this business :).
