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.

Answer:
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.

Answer:
following are the program to the given question:
Program:
x = 0#defining an integer variable that holds a value
if x < 0:#defining if that checks x less than 0
print("This number ", x, " is negative.")#print value with the message
else:#defining else block
if x > 0:#defining if that checks x value greater than 0
print(x, " is positive")#print value with message
else:#defining else block
print(x, " is 0")#print value with message
if x < 0:#defining another if that checks x less than 0
print("This number ", x, " is negative.")
elif (x > 0):#defining elif block that check x value greater than 0
print(x, " is positive")#print value with message
else:#defining else block
print(x, " is 0")#print value with message
Output:
Please find the attachment file.
Explanation:
In this code, an x variable is defined which holds a value that is "0", in the next step nested conditional statement has used that checks the x variable value and uses the print method that compares the value and prints its value with the message.
In another conditional statement, it uses if that checks x value less than 0 and print value with the negative message.
In the elif block, it checks x value that is greater than 0 and prints the value with the positive message, and in the else block it will print the message that is 0.
