Android Question Convert the name of an object into the object itself

[DanteS]

I have some spinners named co_city, co_customers, co_seller, etc, and a rutine Fill_co(co as spinner, data as list) to fill the spinners with the members of a list.

To fill the list I use the PostString method to execute a query and receive the list from the database in the JobDone rutine. I also store the name of the spinner to be filled in a variable named Objecttofill.

Inside the JobDone rutine I use this code:
<code>
Select case Objecttofill
Case "co_cities"
Fill_co(co_cities,list)
Case "co_customers"
Fill_co(co_customers,list)
End Select
</code>

Instead of this code, I would like to do this:
Use a rutine Fill_co2(nco as string, data as list) and call it this way:
Fill_co2(Objecttofill,list)

Inside Fill_co2 I would use a code to transform the content of the string variable nco, into a spinner variable co and then use co.Add to fill the spinner.

How can I perform the last operation

Like this ? move the select to the fill sub:

dim co as spinner
Select nco
Case "co_cities"
co  = co_cities
....

end select
co.add...

Thanks for your reply
No I don't want to write a list of Case "xxx" Fill(xxx) Case "yyy" Fill(yyy) ...
I want to write only something like Fill(nco)

 

[derez]

That is what I wrote:

Sub Fill(nco As String, data As List)
Dim co As Spinner
Select nco
Case "co_cities"
    co  = co_cities
Case "co_customers"
    co  = co_customers
Case ...


End Select
co.add...
End Sub

Another solution:In stead of select, put the spinners in a list and get them from that list by the index number which will be supplied by nco (it will change to int):

Dim co as spinner = spinners_list.get(nco)
co.add ...

Another alternative - instead of a list, a map with the name of the spinner as key and the spinner object as value, then you get the object from the map by the name(nco) as the key.

a map with the name of the spinner as key and the spinner object as value

+1

Thanks again
I am going to try it using the map solution.
I asked because in .net there is something like co=FindControl(nco)
What means the "+1" answer of Erel?

That he think the quoted answer is a GOOD answer. And when "Erel" (our guru) post a +1 then it MUST be for sure a GOOD answer!
