In this tutorial, I will teach you how to create a mini booking system in vb.net. This booking system can calculate the total payments of the guest and it can do payments. This is a good start for you when you are starting programing and do some simple projects.

Creating Application

Step 1

Open Microsoft Visual Studio 2015 and create a new windows form application. booking123

Step 2

Do the form just like shown below. booking321

Step 3

Double Click the Form and do the following codes for adding item in the combobox in the first load of the form. 
  1.         With ComboBox1.Items
  2.             .Add("Standard Room with TV And Electric fan (2 person)")
  3.             .Add("Family Room with TV And Electric fan (6 person)")
  4.             .Add("Deluxe Room with TV And Aircondition (6 person)")
  5.         End With

Step 4

Go back to the design view and double click the “Calculate” button to fire the click event handler of it. Add the following code for calculating the summary of the payments. 
  1.         Try
  2.             Dim totalprice As Double
  3.             Dim personPrice As Double = Val(TextBox2.Text) * 100
  4.  
  5.  
  6.             totalprice = Val(TextBox1.Text) + personPrice
  7.             TextBox3.Text = totalprice
  8.  
  9.  
  10.             Dim change As Double
  11.             change = Val(TextBox4.Text) - Val(TextBox3.Text)
  12.  
  13.             TextBox5.Text = change
  14.  
  15.  
  16.         Catch ex As Exception
  17.             MsgBox(ex.Message)
  18.         End Try
Step 5 This code is for the amount paid. 
  1.         Try
  2.  
  3.             Dim change As Double
  4.             change = Val(TextBox4.Text) - Val(TextBox3.Text)
  5.  
  6.             TextBox5.Text = change
  7.         Catch ex As Exception
  8.             MsgBox(ex.Message) 
  9.         End Try

Step 6

This code is for the clear button 
  1.         ComboBox1.Text = "Select a Room"
  2.         TextBox1.Clear()
  3.         TextBox2.Clear()
  4.         TextBox3.Clear()
  5.         TextBox4.Clear()
  6.         TextBox5.Clear()
