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.
