Making A Calculator Application But Variable Inaccessible?

Nov 3, 2009

I'm trying to make a calculator application. Just as practice, as I'm new to visual basic (.NET 4.0) coding. I've got this so far.

Note, I've not programmed it to do operations yet, I'm trying to get this sorted out first. My issue is, when I enter my numbers, they do not store as a variable, they both store as zero.

VS 2008 Making A Calculator Using Arguments And Functions?

May 6, 2009

Ok. I just took my final for VB and the last chapter we did was on procedures and functions. Functions was the only thing out of this whole semester that I was just completely lost. I'm trying to work on this cause I'm taking Advanced VB next so I wanna know what I'm doing. So I'm trying another tutorial in the book and I'm really lost. Here is what the it wants you to do.

Retail Price Calculator

Write an application that accepts from the user the wholesale cost of an item and its markup percentage. (For example, if an item's wholesale cost is $5 and its retail price is $10, then the markup is 100%)

The program should contain a function named CalculateRetail that receives the wholesale cost and markup percentage as arguments, and returns the retail price of the item.

When the user clicks the Get Retail button, the program should do the following:Verify that the values entered by the user for the wholesale cost and the markup percent are numeric and not negative. Call the CalculateRetail function Display the retail cost as returned from the function.

Here's what the calculator looks like and my code so far.

Public Class Form1
Private Sub btnRetail_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnRetail.Click

Creating A Simple Function Calculator?

Dec 8, 2010

i am going creating a simple function calculator, but I had to first do a design documentation proposal. I now have to update the project proposal with a storyboard or list of menu and screen items to delineate my proposed user screen and menus.aside from the calculator itself there will not be any menus.I also have to list any user data inputs and outputs my application will require and produce, which i assume i can put any numbers that the user inputs into the calculator and their results.

Making An Application That Uses Multiple WebBrowser Controls And Multiple Proxies?

Dec 17, 2009

I am making an application that uses multiple WebBrowser controls, and multiple proxies.The code for changing the proxy settings are as such:

#Region "Proxy"
Public Structure Struct_INTERNET_PROXY_INFO
Public dwAccessType As Integer
Public proxy As IntPtr

[code]....

Note: getRandomProxy gets a random proxy from a list.Problem is that whenever RefreshIESettings(getRandomProxy()) is applied, the proxy will be applied to all of the WebBrowsers, while i would need to have a unique proxy for each WebBrowser. Not having this would just error out the page in the other browsers and so on.

Multiple Operations With A Simple Calculator?

Jul 31, 2011

I've got the bulk of a calculator up and working, however it doesn't like multiple operations. For example 3x5+2= brings up 10 (i.e. 3+5+2) and even doing it in two parts doesn't help, if I enter 3x5= I get 15 then +2= gives me 32 (i.e. 3x5=15 15x2=30 30+2=32). Also I am getting trialing zeros in my command line I can't debug.Note that lblcommandline displays the whole function and lbldisplay just displays the current imputted number.

Public Class frmSimpleCalc
'This code is run when the program starts. Here we 'declare' or basically, define which variables we want, what they are and such.
'So, for this example, we need two variables. The number we are CALCULATING and the one which we will CALCULATE FROM.
Dim lCalcNumberMaster As Long 'The master number is the solution, the number stored and displayed when we click equals.

Making A Function That Reorders The Text Put Into A Textbox?

Oct 8, 2011

I am having trouble making a function that reorders the text put into a textbox. I then have to get that reordered data and put it into a list box.

Basically, 2 words separated by a comma are entered into a text box (say Wash, Car is put into the text box), then I need to get a function that reorders that string and be able to put in into a listbox that shows Car Wash. So it gets the word after the comma first, then gets the word before the comma. It should do this with every string.

Need to use a function for this.

Right now I really just have

Dim Word As String
Word = textbox1.text

'Then the function to reorder the name and return the reordered name will go right here

What this is suppose to do?

- Example, some puts Wash, Car into textbox 1. List Box 1 will display Wash Car.

- Basic, Visual in textbox1, list box 1 will display Visual basic

Visual Basic: Making Multiple Forms For An Orde?

Mar 31, 2012

I've been working on this project for two weeks now and I'm drained from all the hiccups I've come across. Now I've hit a brick wall.I'm making a "simple" order form in Visual Basic 2010 that calculates the amount due for an order and then from the total determines what the shipping will be. I've been able to accomplish the following tasks:accept customer data (name, address, city, state abbreviation, zipcode)calculate total with shipping costs (accurately, for the most part)clear the order form and exitBut the way I have it right now, a customer can only put in 1 order form.

Problem: I have to figure out a way to allow a customer to place an order form for multiple items. (I'll assume that a customer will not place an order for more than 20 items). So what would be the best way to go about saving the information for multiple items then calculating the cost at the end?If it's multiple form creation, how is that done? Is the keyword "Container" the way to go, and how

Private Sub total_mouseleave(ByVal sender As Object, ByVal e As EventArgs) Handles total.MouseLeave
