I'm sorry I was not more clear, my question about a cross platform

going to make
an installer for my program, if I was i would simply put it in the
folder that my
program was created in. However, if I let the user drag the program
where
they like, they may put it on their desktop and then the preference

be on the desktop.
I know the mac keeps preference files in the preferences folder.
However I
don't really know where windows standardly keeps their preference
files. I
don't think there is a place. I was just wondering if realbasic
offered a simply
way to write preference files in a standard place despite the platform.
Thanks for any input,

You may not want to ship with a preference file : You could :
set up all your prefences as properties in your app.
On start up look for the preferences file in your app : (In the App
open event)
dim f as folderItem
dim t as textInputStream
dim a as String
f = preferencesFolder.child(PrefFileName)
if f <> nil then
if f.exists then
t = f.openAsTextFile
if t <> nil then
'Read Prefs here ( UserName = t.readLine) etc
else
defaultPrefs
end if
else
defaultPrefs
end if
else
defaultPrefs
end if
So if you cant find/read the prefs file you set them to defaults.
UserName = "Archibald P Finkelstein"
The in your app close event you can have
dim f as folderItem
dim t as textoutputStream
f = preferencesFolder.child(PrefFileName)
if f <> nil then
t = f.createtextFile
if t <> nil then
etc (t.writeLine UserName)
plus all associated end ifs.
You basically need three methods :
ReadPrefs (Open)
DefaultPrefs (If read prefs doesn't work)
WritePrefs (Close)
Good Luck and Best Regards
