Checkbox "Checked" function with VB Controls

Question

I've multiples CheckBoxes named "CB_0", "CB_1", "CB_2" and so far... I'm trying to change their "Checked" state, but "Controls" doesn't recognize the "Checked" property.

My line of code is like this:

Dim i As Integer = 0
Controls($"CB_{i}").Checked = True

It doesn't works, but if I use this:

CB_0.Checked = True

It works, how can I fix that?

Note:

If I try to change it text, it works:

Dim i As Integer = 0
Controls($"CB_{i}").Text = "Hello"

You need to cast it. Ctype(Controls($"CB_{i}"), Checkbox).Checked — the_lotus

You could use an array and add the name of the controls to the array and then manipulate them from there. — Cheddar

If you used the extension method I gave you in your other question, you would just use the overload with the generic Me.ChildControls(Of CheckBox)().Single(Function(c) c.Name = $"CB_{i}")).Text = "Hello" — djv
