Simple Calculator - How To Work With Print
Jun 11, 2011
I am making a calculator Program to start off on visual basic. I got it to work with MsgBox, but now I'm trying to get it to work with the Print.
MsgBox Example
Public Class Form1
Private Sub Button1_MouseClick(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles Button1.MouseClick
Dim Pizza As Integer
[Code] .....
Say I type in 6 and 6 I'm getting errors saying Example: Conversion from string "youranswer is 12" to type 'Integer' is not valid. I've tried many things, but it's not working. I want to know what I need to do to get it to print out how I want it. Do I need to do some conversions properly somehow?

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.

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.

'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.

Simple Calculator multiplication and division Trying to make a simple calculator. My program inputs numbers and arithmetic operations thru commandbuttons. The numbers, num(n-+1), are odd and the operations, op(n), are even. The code is based on the even op string. Every time a op occurs it is stored in numop(n) to be accessed later. I have all the other operations in sequential order: "*"," "/, "+" and "-". The other similar For-Next loop are the same just interchange the two * for /, +and -. The "+" and "-" work fine in this configuration.
My problem is the multiplication and division does not occur. The numbers and operations line up. The numop(m)=g*h should yield numop(m)=num(1)*num(3). Is there some sort of code to be inserted to accomplish these multiplication and division operations?

I am trying to make a simple resistance calculator for practice. I use text boxes to let the user input the current and voltage, and then a combo box for the units and then a list box to display the results. For some reason no matter which units I select it doesn't convert at all. For example 1/2 will always show up as 0.5 in the list box no matter which units are selected from the combo box. Here is my code.....I know that there is more cases but I only put one to see if it works before I write all of the cases.
Public Class Form1
Dim unitsA As String
Dim unitsV As String

I am trying to develop a simple math calculator that will allow the user to input the right-hand-side (RHS) of an equation into a textbox on the application and have the application evaluate the expression for a given value of x, which is also input
into the application by the user via another textbox.For example, if the user wants to evaluate the following expression,
y = 3 + 4*x + 5*x^2
then they would input into the textbox the RHS of the equation
3 + 4*x + 5*x^2
and then enter a value of x into the another textbox and click on the calculate button.I tried this:
answer = EquationTextBox.Text
but it doesn't work.

I'm new in the programming area and I'm having trouble making a calculator. My question is: How do I make the calculator work using only the keyboard, without the need of mouse.
I tried this:
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs)
Me.KeyPreview = True
End Sub
Private Sub FlowLayoutPanel1_KeyDown(ByVal sender As Object, ByVal e
As System.Windows.Forms.KeyEventArgs) Handles RESULTADO.KeyDown
If e.KeyCode = Keys.NumPad0 Then
[Code] .....
It only works on the text box called Result. I want to know how do I make work in the whole Class, and if it is possible, to make it work on two different Classes without writing twice the same code.

how to do programs in Visual Basic 2010 (It's a Currency Converter/Import Duty Calculator) and I've come across a few problems which are listed below.Basically the project is like this:I'm trying to create a program which converts Hadean pounds, shillings and pence into British Pounds and Pence before it transfers to a form which calculates Import Duty and VAT, after which it gives the final price.So far, I've created a program which is made up of 2 forms and a Splash Screen. The information listed below is for those who want to know more about what I'm trying to do.Once the Hadean price has been converted to Sterling additional import duties and VAT must be added to the Sterling price. Thus control will pass to a 2<sup style="text-indent:0cm;">nd</sup> form where importation duty is added. Depending on the method of importation the followig duty should be added to the Sterling price:
<o:p></o:p>
<o:p> </o:p>Air Cargo Import Duty: 16.5% of Sterling price
<o:p></o:p>
