OK.
Ive managed to get an empty level to trigger sucessfully as a screen-saver in XP-pro.
I havent tried more complex than that yet as I only have commercial and cant create WRS's.
Heres how Ive done it.
I copied my EXE(renamed to SCR), my WDL, and acknex.dll to the C:\WINDOWS folder. (not system32)
The SCR file IS still found here automatically by Display-Properties, and it tries to activate it fine.
But my scr died from "twain.dll invalid image" error, so in the WDL, I put
PLUGINDIR = "%";,
that way I needed no empty dummy directory, and it fires up OK.
Ive only got commercial, so it does a mini-compile splash-screen everytime something changes, or every time the
mini-preview window tries to draw, because our SCR app is being called separately each time.
I dont know if this will affect PRO users though. Suppress the winstart window should do the trick.
OK, thats got it going as a screen-saver. Heres the code I used in mine, its very rudimentary,
but you will easily see where to insert your code, as this following code is largely just
to show how to handle the different paramaters windows will pass in as a screensaver application.
Any questions or issues, just ask.
