you should make one on progress bars. the right way of doing it where it is relevant to the data its representing and not just jerry-rigged like most ppl do. i want to learn how to use progress bars for web browsers, data and even webkitbrowser. thanks.

Is it necessary to use the "Ctype" thing in your parameters of the function you are using. My code seems to work fine when i just do "Dim answer As Double = multiply(txtNum1.Text, txtNum2.Text)" for example.

Add is not a command. Rewatch the tutorial carefully, at the start he creates a private sub CALLED 'Add' then he calls it using 'Add(arguments)'
-
just use x = y + z or x = Cint(y) + Cint(z)
-
Private Sub btnAdd_Click(sender As Object, e As EventArgs) Handles btnAdd.Click
answer.Text = Csng(num1) + Csng(num2)
End sub
would work too….
btw Csng coverts into single 😉 -
'Add' is not declared. It may be inaccessible due to its protection level. I can't use the Add Command!!!!!
-
Private Sub btnAdd_Click(sender As Object, e As EventArgs) Handles btnAdd.Click
Dim num1 As Double = textNum1.Text
Dim num2 As Double = textNum2.Text
answer.Text = num1 + num2
End SubDoesnt this seem much easier? just copy this into each sub and change what answer.text is = to…
