iOS Question for next with step -1 problem

[tufanv]

Hello

I have a strange problem with for next step -1
Code:

Dim n As Int =0

For i=listcevap.Size-1 To (listcevap.Size-TextField1.Text.Length) Step -1

If listcevap.Get(i) = TextField1.Text.CharAt(n) Then
listsonuc.Add("1")
Else
'Exit
End If

next

Now listcevap.size is 12. and textfield1.text.length is 4
so for next is between i=11 to 8 step -1

but during wathcing the logs i see that b4i first gets i=8 than 9 than 10 than 11 instead of first 11 than 10 than 9 than 8 (while geting the values of list )

What am i doing wrong ? I am about to go mad about this.

Strange !
I tried a simple For i = 11 To 4 Step -1 loop and it works as expected.
Can you post a small project showing the problem.

 

[tufanv]

yes sure one moment please

I tried to create a small project it works perfect on it but in my real project it works as i wrote previously. Interesting, I cant find the problem

Add a breakpoint just before the For loop and go through the code step by step.
You may also put Logs showing the values of listcevap.Size and TextField1.Text.Length.

Yes i found the problem. Now the problem is for example textfield1.text.charat(1) = 3
and listcevap.get(i) = 4
i cant get the sum this two numbers it says "Error description: Cannot cast: {Type=Char,Rank=0, RemoteObject=True} to number."
i think b4i sees one as number one as charachter. How can i make it see both of them as numbers so i can get the sum for example ?

CharAt(1) returns a Char which you cannot use for arithmetic operations.
Try to use
Dim n = textfield1.Text.CharAt(1) As Int
before calculating the sum.

Dim y= textfield1.Text.CharAt(n) As Int gives the same error : "Error description: Cannot cast: {Type=Char,Rank=0, RemoteObject=True} to number."

fixed the problem by :

dim y as char = listcevap.get(i)

so i compare two chars and if they are same it is enough for me. Thanks for all help
