Can the Sender be applied to a Spinner view

[Mahares]

When I click any of the 3 spinners, the Msgbox is completely ignored and bypassed. See below code excerpt:

Dim spnCode1, spnCode2, spnCode3 As Spinner
.
.
spnCode1.Initialize("MySpinnerCode")
spnCode2.Initialize("MySpinnerCode")
spnCode3.Initialize("MySpinnerCode")

Sub MySpinnerCode_ItemClick (Position As Int, Value As Object)
Dim Send As Spinner
Send=Sender
Msgbox(Send.SelectedItem.SubString2(0,2),"") 'displays the first 2 characters of the string: 0=1st chr, 1 is 2nd, 2 is excluded
End Sub

Unfortunately, you don't tell us the whole story!
The code below works fine:

Sub Globals
    Dim spnCode1, spnCode2, spnCode3 As Spinner
End Sub

Sub Activity_Create(FirstTime As Boolean)
     Dim i As Int
     
    spnCode1.Initialize("MySpinnerCode")
    spnCode2.Initialize("MySpinnerCode")
    spnCode3.Initialize("MySpinnerCode")
    
    Activity.AddView(spnCode1, 10dip, 20dip, 200dip, 50dip)
    Activity.AddView(spnCode2, 10dip, 80dip, 200dip, 50dip)
    Activity.AddView(spnCode3, 10dip, 140dip, 200dip, 50dip)
    
    For i = 0 To 4
        spnCode1.Add("1" & i & "a") 
        spnCode2.Add("2" & i & "b") 
        spnCode3.Add("3" & i & "c") 
    Next
End Sub

Sub MySpinnerCode_ItemClick (Position As Int, Value As Object)
    Dim Send As Spinner
    Send=Sender
    Msgbox(Send.SelectedItem.SubString2(0,2),"") 'displays the first 2 characters of the string: 0=1st chr, 1 is 2nd, 2 is excluded
End Sub

You are missing to say where the Spinner were added.
If they were added in a layout file you MUST NOT initialize them once more in the code, they are automaticaly initilaized when the layout file is loaded.
If thy are not in a layout file you must add them to the Activity in the code.

Best regards.

You are correct Klaus. I did initialize the 3 spinners in the designer already. I removed the initialization from the code and it solved my problem. Thank you for the tip.
1. Is there a way that B4A warns of an error when a double initialization is made, because in my case I did not get any warning. That portion of the code was simply ignored and jumped over.
2. Also, I would like to review my OWN threads that I initiated and save them to an offline file on my PC for future reference. Can this be done?
Best wishes for a happy holiday.

1. No, but it's not really an error.

2. I've never tried it, what I do for information I want to keep for a certain subject is a Word file with the links to the sites where I found it.

Best regards.

It would be very helpful to have a button on the main home page of the forum that says: 'View my threads'. It would display all the threads posted by the member logged in. This can prevent repetitive threads that have already been addressed by the member in question.
