change listbox extension reference

[dkl]

listbox #1.1, Auto$(), [dummy3], x2, 50, w2,300
listbox #1.2, Lunch$(), [dummy3], x2, 50, w2,300
1.......24 listboxes all in same position and accessed by a relevant button

[dummy3]
WindowWidth = 500
WindowHeight = 45
UpperLeftX=705'int((DisplayWidth-WindowWidth)/2)
UpperLeftY=485'int((DisplayHeight-WindowHeight)/2)
BackgroundColor$ = "darkred"
textbox #inf3.tb, 10, 10, 450, 25
stylebits #inf3.ok, _BS_DEFPUSHBUTTON, 0, 0, 0
button #inf3.ok, "OK", [OK3],UR, 5, 10, 30, 25
on error goto [OK3]
open " " for Window_popup as #inf3
#1.1, "selection? selected$" '<----I SIMPLY WANT TO CHANGE THIS CODE ......... #1.1 to #1.2 or #1.3 etc
#inf3.tb,selected$
wait
[OK3]
close #inf3
#1.1,"select 0"
wait

I simply want to able to change this short piece of code #1.1 to #1.2 or #1.3 etc, so that I can use the same routine to work with 24 listboxes instead of having to copy the whole code 24 times. I only need to change ONE digit! I've tried using variables and arrays in various forms, but that doesn't work.

I could have 24 if/then statements, but that seems a bit silly. There must be a simple way? Is there an easy way to change the reference of the listbox extension?

I think you can use handle variables for this.

hndl$ = "#1.1"
#hdnl$, "selection? selected$"

[Rod]

You need to use a handle variable. First of create a string that represents the handle, s$="#1.1" then use that in your code as a handle variable by prepending # So #s$ "selection? selected$"

You can amend s$ in a loop and so loop through 24 handles easily.

Brilliant! Thanks you so much. I've not seen any mention of being able to do that anywhere. Probably couldn't see it for looking!!

I've not seen any mention of being able to do that anywhere.

It's in the manuals
