Identify the error in the following code:
Private Sub btnCalculate_Click(ByVal sender As System.Object, _
ByVal e As System.EventArgs) Handles btnCalculate.Click
' Declare some variables
Dim sngNumber1 As Single
Dim sngNumber2 As Single
Dim sngSum As Single

' Get the two numbers
SngNumber1 = txtNumber1.Text
SngNumber2 = txtNumber2.Text
' Calculate their sngSum... is the next line working?
SngSum = sngNumber1 + sngNumber2
' Display the result
LblSum.Text = sngSum.ToString
End Sub

Question

Quizplus · Accepted Answer

The variables sngNumber1 and sngNumber2 are being assigned values directly from text properties (txtNumber1.Text and txtNumber2.Text) without converting the text to Single data type using a conversion function like CSng. This can cause a runtime error because the text properties return strings, not numbers.
