I read somewhere else that when you make a screensaver, you should include a text document that the .scr will check constantly when running to see if the screensaver is running, to avoid running the screensaver again and again when the PC's delay time has elapsed, e.g. if the PC is set to activate the screensaver when the PC is idle for 30 minutes, then a screensaver made in DB will run every 30 minutes, even if it's already running. how would I go about making the program check if the screensaver is running, to avoid running out of memory? Is it something to do with the "execute file" command, e.g.

open to read 1,"saver.txt"
read string 1,a$
close file 1
if a$="no" then execute file [screensaver]

...etc.

i have never fully understood the "execute file" command, even though i have the book and read the help in DB itself.

I don't know if thats true, but what you could do is create a file when the program is running, and if the file already exists then it would end the program. And then delete the file on a natural close of the screensaver.

from what i understand you need to write a while loop.

while mouse click and or any keys are being pressed, run the screen saver.
this terminates the screen saver when you move the mouse or press a key, hence what they all do.

i know i need a loop to run a screensaver, but what i mean is if the computer is set to execute a screensaver after 10 minutes of being idle, then a DB made screensaver would execute every 10 minutes after that, even if still running, therefore using up too much RAM.

scroll down to Van B's posts in this thread to see what I mean.

p.s. I don't know why I bothered asking. All the information is in the above thread! Oops!

oops by your hand, oops by my hand, not knowing the timed execution had anything to do with it.
cheers, I will carry that on to the next user who needs screen-saver advice.

I did a screensaver test... it's a screensaver that opens a file and writes how many times the screensaver was activated.

I selected it and put the wait to 1 minute and let my computer go for 15 minutes. When I moved the mouse I opened the file it created and it only ran one time during the whole 15 minutes.

You don't have anything to worry about.

Here's the code:
