1. How do I re-use a procedure?
Seems like today is the day for my procedures not to work. I have a
procedure (shown below) which I use to populate a listview control. It
works great.
procedure Print_to_Screen( integer self, integer even, sequence parms)
-- some code
end procedure
setHandler(MenuP_Scn, w32HClick, routine_id( "Print_to_Screen" ))
I want to use this procedure a second time in another part of my program
so I inserted the code below
as part of the second procedure.
Print_to_Screen (MenuP_Scn, w32HClick,"")
I get the error "Print_to_Screen" not declared". What's wrong? I have
used this technique before
without a problem, but I'm obviously missing something here.
2. Re: How do I re-use a procedure?
I'm guessing you're using the IDE here, but it doesn't really matter.
What has happened is that the place you are calling the procedure from is
higher in the source code than the place it is declared. Euphoria only looks
up for procedures, not further down. What I suggest you do to fix this is to
replace the Print_to_Screen call with:
invokeHandler(MenuP_Scn, w32HClick)
This takes care of any code location issues, and is more robust, cause if
you change the name "Print_to_Screen" to something else, you don't have to
change the above call.

Oops, my mistake...
invokeHandler is actually a function, not a procedure.
VOID = invokeHandler(.........
should work a bit better.

This is because it was incorrectly given to you. It should read ...
VOID = invokeHandler(MenuP_Scn, w32HClick, {} )
and of course you will need to have ...
object VOID
defined near the top of your code somewhere.

6. Re: How do I re-use a procedure?
pssss..*whispers, "Hey, Ron"* maybe that's because some things were
simplified so much that they don't function as well anymore? *grins* like
forward referencing functions?
