I have to create an app that computes the amount income tax that a person has to pay, depending on salary. Income tax should be calculated for each portion of income in each range.
Here are the following income ranges and taxes rates:
Not over $7825=10%income tax
$7825-31852 = 15%income tax
$31851-77100 = 25%income tax
$77101-160850 =28%income tax
$160850-349700=33%income tax
Over $349700 =35%income tax
Here is the code so far:
Public Class IncomeTaxForm
Private Sub calculateButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles calculateButton.Click
Dim IncomeTax As Double = 0
Dim salary As Double = 0
[Code] .....
I keep getting zeros. Do I have to add another equation for each case?
I am having difficulties getting a case to behave like I want it to. I have to calculate income tax using a case statement. For example if someone makes $7000 or less then they are charged a 10% tax of their input income, if they make $7000 to $30,000 it will bee 10% on $7000 and 15% on the remainder of input income and so on and so forth.determining how to set up a functioning case statement like this?
I am developing Restaurant POS Application with home devliery module. Customer call to restaurant and give the order. so whenever customer calls comes i need to show the pop-up on my desktop application with particular customer information. Please guide me how to do this. I am using visual studio 2008 (vb.net)

i have a program using a select case to convert letters to special charaters. My question is how can I get the code to read upper and lower case letters without having to put the upper case letters in my select case statement. Example: Part of my code is
When my form loads it adds some handles (using AddHandler) to a sub (showStatus). What this sub does is checks which control activated the sub (using sender.Equals) and displays text in the status label (status) accordingly.For this I use an If...Then statement for each possibility. There are many possibilities and my code get cluttered. Is there a way to do the same thing with a Select...Case statement. I tried: Select Case sender Case tbOne : status.Text = "blahblahblahblahblahblah" End Selectwhere: tbOne is a textbox, status is a StatusLabelIt gives me an error though, saying "Operator '=' is not defined for types 'Object' and 'System.Windows.Forms.TextBox'."Any ideas on how I can get this to work with a select case statement?
Firstly Case 2 runs. Throws exception. And right after this debugger shows that next processed statement is Case Else. Only after Case Else throws own exception Catch block start working. I've never seen this trick. Why can this happened?I'm sure the block is entered once (not like this:first enter hit Case 2 and second hit Case Else).
Update:-To Matt Wilko. Thank you for answering. I've switch to Strict On in Options of VS2010 but nothing has changed. Command is variable, not function. Watch tool shows that on each step Command is the same ( Command = 2).
Fixed. Yeeaaaahhh. I simplefy code to Try Select Case 2 Case 2
[code]....
and change project to Console app. This works as I mention. The fix was in Release mode. I was debugging in Release mode. When I switch to Debug mode everything goes as it should.
I wanted to read input equation by user A+B and assign input user value to A and B to ask them to add and give answer. But I just can't get the code to work. I using VS2005 and VB.Net.[code]
Program Description: Fortuitous Dice is a game that requires two dice be rolled, one at a time. If p and q are the numbers rolled on the first and second die, respectively the value of the roll in the game is determined as follows:
P Q Rule (value of the roll and condition) Even Odd 2P + Q Odd Even P + 2Q Even Even P + Q When P not = Q P When P = Q odd Odd P + Q When P not = Q 3Q When P = Q
I have a decent understanding of the logic, the content. I'm working on a puzzle and I'd like to write a short program. I'm looking to fill in the following variables: AB.CDE FG.HIJ (they're part of coordinates, and the puzzle is part of a geocache) The puzzle asks you to determine which numbers correspond to certain colors, like this:
[code...]
I need to define A-J as >= 0 and <=9. I also need to say that each color is >= 0 and <=9, but that no color can be equal to another color (purple ≠yellow, orange, etc). some number combinations won't work. Purple and yellow can't be 2 and 5 respectively, because that'd produce a negative number. I'm guessing that there will be more than one possible result. So how do I create an equation that calculates this.
I would like to read a user's input equation or expression as a string (such as "y=5*(x+6)" or "cos(3)^2") and have the program evaluate it mathematically. Does .Net have any classes that could do this? Obviously, the compiler can already take a programmer's coded equation and evaluate it. Of course this is a different matter, but is there not a way to harness that same power with runtime user-created equations? Serialization or anything?
The other option (I guess) would be to create my own equation-generator - breaking an equation down into a binary tree of the numerical values and the operations I suppose. Aside from being a nontrivial task, my program needs optimal performance as these equations are in large loops. At the very least, this would add several conditional evaluations to each equation run - dunno if that adds up.
The project is "kWh counter", that is, a simple program that calculates the power usage.The incoming numbers are the Power of the appliance (lightbulb) and the voltage (230/120).The formula is W=P*t that is multiplication of the power and the time it is used.I thought to connect it with a timer and the passing secconds multyply with the power, and, write the ussage on a label.This would be something like a simple digital power counter.Note that the voltage is not necesary.I am from europe where the standards are 230V.
My assignment is to get the Get Monthly Income (Num1)Get Monthly Home Rent/Mortgage (Num2) Get Other Monthly Payments (alimony, child support, student loans) (Num3) Display Allowable Monthly Car Payment Display Maximum Car Value (interest rate based on credit) (answer) Public Class Form1
What I need to do is automatically generate a specific PIN number based on the current date. The formula goes like this: MMDD + 1234 = PIN. (ex. Date = 3/26/2012 -> 0326 + 1234 = 1560; With 1560 being the PIN number. I then need the PIN number to display as text, but that's the easy part, I really just need assistance with getting the date information in the proper format for the equation.
after a lot of research on formatting Maths equations, apparently using MS equation edior is the easiest way to do it. But, I have no idea how to use it in VS 2008.
I am rotating a picture dependant on the mousemove.
Private Sub PictureBox1_MouseMove(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles PictureBox1.MouseMove
[code]...
To simplify the part I am having problems with: rotationX = CurrentPositionX + ((InitialPositionX - MousePositonX) / SlowDownDivisor)
As an example, this occurs in both X and Y; If I click and drag in the X + Direction and release the mouse button it does exactly what I want, rotation in the positive direction. If I click and drag in the X + Direction and then drag in the X - direction, the rotation continues to be positive, it doesn't reverse. If I release the button and then click again and move in the X - direction the rotation is negative as it should, but it will continue to rotate in the negitive direction until the button is release.
In our school theres a programming class and the teachers gone for the week and the sub is starting to get very frustrated, so I offered to help in any way i can. I have never programmed Visual Basic but I have programmed Ms-Dos, Javascript, HTML, *.vbs, *.ahk, *.gml, and a variety of other languages.
The class is going to build a program that calculate how many rabbits are born in a family. So when they click the button it shows in a text box the actual equation and then the answer after the equal sign that where i assume concatenation comes in.Here's the code I've thrown together for when the buttons pressed:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim RabitAmount As Integer Dim ShowEquation As String
[code]....
I got the equation to answer it self and show in the text box but it won't show the equation?
I want to display an equation prior to solving it. Obviously in MS word etc I can use equation editor to write an equation, but I'm writing my own program.
Is there an easy way to display an equation. Obviously I could use text to write eg as text "a=b^2-3(c-d)/5" and everyone here would have little problem interpretting what I want but I want this to be accessible to 12 year old children.
Alternatively I could try and manipulate lots of text boxes one on top of the other to try and explain what I'm doing
The third alternative I thought of was to write in equation editor export the graphic and then import a graphic.
I'm sure I must be trying to reinvent the wheel - which I believe is the one thing OE programming is supposed to avoid.
I put this mathematical formula in VB 2008 Express Form and I have the result show in TextBox and every thing is good so far and my question is if I have a table of numbers for example if the answer in the TextBox is 0.00098 and my table show : 0.0001 to 0.00100 = 7 0.00101 to 0.002 = 8 0.00201 to 0.003 = 9 Etc I need the number 7 to be displayed in label 1 so how can I do that?
I have a boolean condition that I want tthe program to recognize changes when they occur. Currently in order for the program to recognize a change I must restart the program.I have tried using a public timer but that didn't work.
I am re-writting the text file "MEASURE UNITS.TXT" labeled (D1B). Depending on this boolean equation different options become available in other parts of the program.I need the program to re-adjust the boolean equation on the fly.
