If Option Strict is set to On, which of the following statements will assign the contents of the txtSales control to a Double variable named dblSales? a. dblSales = txtSales.Text b. dblSales = txtSales.Text.Convert.ToDouble c. Double.TryParse(txtSales.Text, dblSales) d. TryParse.Double(txtSales.Text, dblSales)
If Option Strict is set to On, which of the following statements assigns the sum of two Integer variables to the Text property of the lblTotal control? a. lblTotal.Text = (intN1 + intN2).ToString b. lblTotal.Text = intN1.ToString + intN2.ToString c. lblTotal.Text = intN1 + intN2.ToString d. lblTotal.Text = ToString(intN1 + intN2)
The expression in which of the following assignment statements will not calculate correctly?
a. lblTotal.Text = Val(txtSales1.Text) + Val(txtSales2.Text)b. lblTotal.Text = Val(txtSales1.Text + txtSales2.Text)
c. lblTotal.Text = Val(txtSales.Text) * 1.1
d. none of the above because all of the expressions will calculate correctly
