Private Sub cb1_TextChanged(sender As System.Object, e As System.EventArgs) Handles cb1.TextChanged
    ok = Convert.ToInt32(cb1.Text)
    ok = CInt(cb1.Text)
    kk = Convert.ToInt32(cb2.Text)
    kk = CInt(cb2.Text)

Solution 1

That is going to depend on your data - i.e. whatever the user types.
If you just want a number, why not use a NumericUpDown - they can even apply upper and lower limits.

Alternatively, use the Int32.TryParse[^] method instead?
