Android Question I am strugling with a Map type

[FrancoisPG]

I am busy with a Kakuro game and would like to use the Map type. In my Process_Globals i have declared the following:

Type SplitBlk (Index As Int, HorLen As Int, HorVal As Int, VerLen As Int, VerVal As Int)
Dim SplitBlock As Map, spBlk As SplitBlk

Then i have the following sub where I Put an index and spBlk of SplitBlk type in the map. My problem is that if I look at my Map at the end of the loop, I have all the index's I have added, but all the values in spBlk are the same. They are all equal to the values of the last spBlk added?

Sub CalcNumbers
ind = 0
Do While ind < modGenOplos.aSelle
If kKur(ind).Tipe = Tipe.Split Then
spBlk.Initialize
spBlk.Index = ind
CalcSplitRight(spBlk)
CalcSplitDown(spBlk)
SplitBlock.Put(ind,spBlk)
End If
ind = ind + 1
Loop
End Sub

You should Dim spBlk inside the loop just before you initialize it.

You should Dim spBlk inside the loop just before you initialize it.

I will try it, I have put a break point at the Put and every time spBlk has got different values and when I exit the loop all the values are equal to the values of the last spBlk which I have Put.

Thank you, the Dim just before the initialize has resolved it! Just for me to understand it, does this happen because there was only one instance of spBlk and at the end of the loop all the entries in the Map has actually pointed to this one instance?

Thank you again

Yes.
Each time you Dim it creates a new object (and unreferences the previous one).
If you dont Dim, the same object is used. So at the end even after you put your objects in the map, they are still refering to spBlk.
