• Use the three option statements found in figure 3-23 (p. 136)
• Do not leave any blank blocks of code or events
• Use proper access keys and appropriate tab order
• Include a default button when appropriate
• Lock form controls
• Include documentation comments on the main form code, as well as code comments for each major line of code
• Add the solution folders to a created folder with the following naming convention: CourseNumber_LastNameFirstInitial_LabXX
• Folders should be compressed

 

I will send the rest in another question 

Answer 1

Start
	Declare variable previousMeterReading As Double
        Input previousMeterReading 
        Declare variable currentMeterReading As Double  
        Input currentMeterReading 
        Declare variable gallonsWaterUsed As Double
        Set gallonsWaterUsed=currentMeterReading - previousMeterReading
        Declare variable totalChargeWater As Double 
        Set totalChargeWater=19.5 + 0.00175 * gallonsWaterUsed
        Display gallonsWaterUsed
        Display totalChargeWater
Stop

Form

Code:

Public Class Form1

  Private Sub btnCalculate_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnCalculate.Click

    Dim previousMeterReading As Double = Double.Parse(txtPreviousMeterReading.Text)

    Dim currentMeterReading As Double = Double.Parse(txtCurrentMeterReading.Text)

    Dim gallonsWaterUsed As Double = currentMeterReading - previousMeterReading

    Dim totalChargeWater As Double = 19.5 + 0.00175 * gallonsWaterUsed

    txtGallonsWaterUsed.Text = gallonsWaterUsed.ToString("N")

    txtTotalChargeWater.Text = totalChargeWater.ToString("C")

  End Sub

End Class
