Android Question [SOLVED] Type and List

[lemonisdead]

Hi,

I am sorry, I am lost. Could you please point me to a thread or tutorial about (I don't find one) ?

I am trying to understand how to store/read a Type into a List and Save/Read the List from a file. I get a casting error while trying to recover the type from the list.

I have thought/wrongly understood (?) that I could recover my types line by line from the list.

Many thanks.

Sub Globals
       Type tRec(Name As String, Value As Int)
End Sub

Sub TestRead
        Dim tList As List
        tList.Initialize
        tList=File.ReadList(File.DirInternal,"TestRec")
     
        Dim nPos As Int
        nPos=tList.Size-1
          
        Do Until nPos<0
            Log("Reading line: " & nPos)

            Dim Temp As tRec 'Type tRec
            Temp.Initialize

            Temp=tList.Get(nPos)
            Log(Temp.Name & " : " & Temp.Value & CRLF)

            nPos=nPos-1
        Loop
End Sub

ReadList returns strings.
I think you needs ReadObject.

Many thanks thedesalotesoul : you are powerful (as usual)

@thedesolatesoul is correct. I'll just add that you can use KeyValueStore class as well. It is simpler and more powerful than RandomAccessFile (in this case).
