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

Dim Pizza As Integer

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?
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
TextBox1.Text = ""
End Sub
This is to Clear all numbers but I don't know how to Clear just one number. for example i want to do 23 once a user clicks CE, i want to make it show 2
I am making a calculator at the moment and the plus works and so does the minus well the minus does the FIRST time but not the time after that.you would normaly get 2, but instead it says that the answer is -3.I have attached the calculator so that you can have a look.
View 3 RepliesI'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

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>

I have an application that requires data be entered, and after entering, a button is clicked to process that data. Clicking the button works just as it should--the data is processed properly. In constructing a test module, I provide a set of data values, followed by:
btnWhatever.PerformClick()
Nothing happens. I have used this syntax for years, and it has always worked flawlessly. I have triple checked everything else and isolated the problem to the failure of the PerformClick(). The PerformClick() is in a test subroutine that does nothing but fill textboxes and labels with default data, then calls the PerformClick() on the button to begin processing. Again, the button works fine, the data is entered as it should be, but the PerformClick() does not fire the click event.
I have a form that works on my local Machine I created into. I have Office 2007 on this machine. I created the Form with the Excel 12 Reference. I move the Entire conetence of the Project folder to my work computer. Which has Office 2003. Do I need to recreate the form with the Excel 11 reference. I could not get the form to work on work computer. IT has a com error. I am acessing the EXE for the debug folder w/in the Bin Folder.

I've made a simple calculator, everything works except for the adding (+) function. Such as 3 + 4 = 34 (which it doesn't). It takes it as a string, rather than a number.
Here's what I have so far:

Again, the problem is the adding is not functioning.

Sorry in advance. I emailed myself my coding since I don't have vb on my personal computer. Sooo, the format is going to be off. But my program allows the computer to generate a random date. The user has to guess what day of the week the random date lands on. I have written the whole code. It all works except when user checks his/her answer. The answer always comes up as incorrect. Here is the coding:

You need to design and create a program that accepts input of employee name, employee type, and the number of hours worked each week for two weeks.You must be able to select an employee type. An employee of type Trainee makes $10 per hour. An employee of type Regular makes $15 per hour. An employee of type Manager makes $20 per hour.The program should calculate the employee�s pay for the week. The employee should receive 1 � times the regular pay for any hours worked over the prescribed 40 hours in a week. The program should output the following information:

I need a little help in programming a console calculator.I'll start by saying that VB is a new programming language for me. I started a class in school that uses VB to teach an introduction to computer logic and programming. It's not the first language i have learned, but it the first one that i have gotten in depth with in console apps.I have a basic set up of asking the user for the first number, then the operator, then the second number.I'm currently using a Select Case statement to start the calculation area of the program, a Do Until at the beginning of the Select Case for a repeat, then it proceeds to getting the numbers and operators.
I'm also wanting to get all the possible math operators that VB provides included.What i'm hoping for is to clean up my code and make it to where the program asks the user for the equation itself. Example.
Console.WriteLine("Enter the equation")
equation = Console.ReadKey()

I am new to the MSDN forums and was wondering if you could kindly help me with a learning project.I have created a calculator with a simple addition function button and was wondering if the method I used to create it is efficient and how I may go about adding additional functions such as a minus function.Will my current code allow m to implement a minus, multiplication, or division function easily?How do I add a minus function and would adding a multiplication or division function? Also would can I use the same global variables to do this.[code]
