Increasing Textbox amount as button is clicked.

dhru patel

Hello,

I have to make a soda machine software. I'm very new to programming and I'm trying to make this thing work. I have buttons for Dollar note, quarters, dime, nickel. And what i want is the user to click on it and show the incremented amount in textbox. I'm just so frustrated because I simple don't know how to make it work. i tried ++dollarAmount ad everything but no success.

Im putting the code to form1.cs and I've also attached the entire zip file if you want to take a look at it.

using System;

using System.Collections.Generic;

using System.ComponentModel;

using System.Data;

using System.Drawing;

using System.Linq;

using System.Text;

using System.Windows.Forms;

namespace VendingMachine

{

public partial class Form1 : Form

{

public Form1()

{

InitializeComponent();

txtboxInstructions.Text = "Please click on the amount that you would like to enter.";

}

private void btnClear_Click(object sender, EventArgs e)

{

txtBoxAmount.Text = "";

txtBoxSelection.Text = "";

}

Accepted answer
Created a Transaction object to keep track of the money and resets everytime it clears. You will need to add code for other conditions, but it covers the main idea. You may want to change the data structure used if you want.

Alright, so the way it's supposed to work is this..It's a soda machine. I have the products on left and they will have prices and like a unique number associated with it. Let's say the user wants to buy a pepsi bottle, he would click on a Dollar sign, and probably on quarter buttons twice to pay $1.50. I want to show the amount in the textbox. So as they click on coins or dollar note, it shows the incremented amount.

Hi,

I had a look at your project. Good design..

But i cant understand the logic. On click of dollar button what value should be increased?.

What is the use of calculator-like buttons and Enter,Clear button. Can say clearly..

And one more thing while uploading any project into site please delete the obj & bin folders. because it increases the size if the zip file. in your case the zip file size is 17 MB. but if you delete the bin&obj folder it will be 20 - 50 KB only.

Thanks.
