Converting String to Integer

[Denden]

Hi everyone could you help me fix my code?

I tried to use convert.toint32 and integer.parse but no luck.

Here's my code:

   Private Sub Form2_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        'Label1.Text = TextBox1.Text * TextBox2.Text
 
        Dim int1 As Integer
        int1 = System.Convert.ToInt32(TextBox1.Text)
        Dim int2 As Integer
        int2 = System.Convert.ToInt32(TextBox2.Text)
        Label1.Text = int1 * int2
 
 
    End Sub

integer.parse or integer.tryparse would work.

i already use them but no luck sir

What kind of number is in the fields? This works just fine in a project I just created.

        Dim int1 As Integer = 0
        Dim int2 As Integer = 0
        Integer.TryParse(TextBox1.Text, int1)
        Integer.TryParse(TextBox2.Text, int2)
        Label1.Text = int1 * int2

i am trying to perform a multiplication. ive got two textboxes and one label. i put my code on the load event handler that when someone opens up that form and they will enter numbers, those numbers will be multiply upon typing

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
 
    End Sub
    Private Sub doMath()
        Dim int1 As Integer = 0
        Dim int2 As Integer = 0
        Integer.TryParse(TextBox1.Text, int1)
        Integer.TryParse(TextBox2.Text, int2)
        Label1.Text = int1 * int2
    End Sub
    Private Sub TextBox1_KeyUp(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles TextBox1.KeyUp
        doMath()
    End Sub
 
    Private Sub TextBox2_KeyUp(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles TextBox2.KeyUp
        doMath()
    End Sub

WOW. this is my first time using the keyup event. i am thinking that i do it inside the form load, i was wrong .. thank you sir.
