Part cost Calculator Modify the GUI in your program to look like the following GUI. To do that you need to add the following to the GUI in the starter program. A text box to accept the part number (Only one is allowed A1B) Note the user may enter spaces before or after the part number and may enter the letters in lower or upper case. You program must accommodate that.

Imports System.Text.RegularExpressions

Public Class Form2

   Private Shared Function Num1(ByVal val As String) As Integer

       Dim retrnVal As String = String.Empty

       Dim collect As MatchCollection = Regex.Matches(val, "\d+")

       For Each mat As Match In collect

           retrnVal += mat.ToString()

       Next

       Return Convert.ToInt32(retrnVal)

   End Function

   Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click

       TextBox1.Text = Num1(TextBox1.Text)

       Dim Total As Integer = 0

       Dim A1b As Integer = Convert.ToInt32(TextBox1.Text)

       Label1.Text = 250

       Label2.Text = 25

       If Convert.ToInt32(TextBox1.Text) = A1b Then

           If Convert.ToInt16(Label1.Text) < 10 Then

               Total = 10.5 * Convert.ToInt16(Label1.Text)

           Else

               Total = 8.75 * Convert.ToInt16(Label1.Text)

           End If

           If CheckBox1.Checked Then

               Total = Total + 10

           Else

               Total = Total + 5

           End If

           TextBox2.Text = Convert.ToString(Total)

       End If

End Sub

Explanation:

Please check the answer section and the attachment. Also, please check the method. We have used the regular expression over there. And we have imported the regularexpression library for that. And this is to ensure we can read integer from textbox no matter whether the user inputs empty spaces or characters in lower and upper case in between.

you have to email it to yourself from your phone then download it to either google drive or you computer files. then you can go to where ever you saved it and select it and then copy and paste it. or you could attach it to your question when you are writing it which would be much easier. for example: go to the attachment.
