when the preview command line is passed to your .exe it also contains the handle of the preview window, like this:
/P:165468
you must parse this and use the number after the ':' as a handle to use as a parent for your .exe's child window (preview) (you can't do this in DBPro)
Also to correctly handle a screensaver you should check for multiple instances of your app running and deny others from starting using a mutex. (you can't do this in DBPro)
psuedo code:
Select parameter
Case "" `double clicked
startsaver() `or configuresaver()
Case "/A" `check password
verifypassword()
Case "/C" `'Settings' button clicked in the screensaver dialog
configuresaver()
Case "/P" `when the preview is requested in the screensaver dialog by selecting this screensaver
startpreview()
Case "/S" `launch the main screensaver after an interval or by pressing 'Preview' in the dialog
startsaver()
EndSelect
Its alot more complicated than simply renaming your .exe to .src
