  The code below is for a mini calculator that add two numbers entered in the two text boxes. I am using visual web developer 2005 express to develop. But it's always showing errors that "Operand1TextBox.Text and Operand2TextBox.Text are not declared"

  Protected Sub TextBox1_TextChanged(ByVal sender As Object, ByVal e As System.EventArgs)
  
  End Sub
  
  Protected Sub AddButton_Click(ByVal sender As Object, ByVal e As System.EventArgs)
      Dim op1, op2, result As Single
      op1 = Convert.ToSingle(Operand1TextBox.Text)
      op2 = Convert.ToSingle(Operand2TextBox.Text)
      result = op1 + op2
      resultLabel.Text = result.ToString()
  End Sub

  Why Operand1 and Operand2?

  op1 = Convert.ToSingle(TextBox1.Text)
  op2 = Convert.ToSingle(TextBox2.Text)
  

  This is just fine. You have to pass values by the names of the controls you have used.
