Write A Program To Compute The Roots Of A Quadratic?

Nov 25, 2010

i cant seem to figure out where i am going wrong with this. im new to programming and havent really ran into many problems yet but this one has me baffled. i need to write a program to compute the roots of a quadratic i have my code and i am not getting any errors problem is i must check that the a value is nonzero so when i set my if block and use "if a = 0" and then display message it seems that it doesnt pass the values on to the else when a does not = 0.

Develop A Simple Math Calculator That Will Allow The User To Input The Right-hand-side (RHS) Of An Equation Into A Textbox?

Dec 12, 2011

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.

Finding The Roots Of Equations?

Nov 13, 2010

I am trying to make a program to calculate the roots of a polynomial equation using the bisection method. I have designed the program so the user input a range of x values (x1 and x2) to solve for the root. When I debug the program I keep getting zero for the root. I know there must be something wrong the way I have my loop setup that keeps giving me a zero root. Here is what I have so far

VS 2010 - Remove All Children But Keep Roots

Feb 11, 2011

I know you can run

treeview1.Nodes.clear()

and that removes everything, but how, or it is even possible, to just remove children and keep the parents. I added the root nodes in the properties window and built my code around those, but clearing also removes them. Then of course that makes the code error as it can't find the code when I re populate the treeview.

IO.Directory.GetDirectories() Finds Directories That Don't Actually Exist?

Jul 28, 2011

The sub below will show all of the directories contain with a directory

Code:
Private Sub showDirectories(ByVal rootDirectory As String)
Dim rootDirectories() As String = IO.Directory.GetDirectories(rootDirectory)

[code]....

When I run this code I can use any directory as the root directory except My Documents.When I use the directory path with My Documents, as well as finding all of the folders contained in My Documents, it finds three extra: My Music, My Pictures and My Videos. Those three folders do not exist at all in My Documents. I have checked hidden files and folder and they are definately not there yet the showDirectories() sub says that they are.The exact error is: Access to the path 'C:UsersMichaelDocumentsMy Music' is denied.It's dened because the folder doesn't exist. I have checked myself using Windows Explorer!Despite this, when I type 'file:///C:/Users/Michael/Documents/' in the address bar of Google Chrome, it shows all of the files and folders in My Documents and, guess what, it shows the folders My Music, My Pictures and My Videos. But Windows Explorer doesn't show these! The strange thing is, for each of the folders, the last Date Modified was 23/01/2011 13:42:49 exactly. Each of the folders was last modified at that exact second simultaneously!I have 3 "ghost" folders "haunting" my My Documents. Is there any programs out there that perform "exorcisms" cause I am seriously freaked out!Perhaps this is the wrong place to post this. When I started writing this thread, it was about Visual Basic but now I realise it has nothing to do with programming at all.

DB/Reporting :: OleDataAdapter With Parameters Finds 1 Of 3 Matching Records

Apr 15, 2008

I am using Windows XP and Visual Studio 2003 .NET in VB.

I have created a parameter query using data controls on a form. The SQL works when I paste it into MS Access (and set the values to those I type in the input form) it returns 3 records. In the VB form I only ever get the first matching record. By changing the input by sorting in different orders I still only get the first matching record ( a different one). If I alter my input so the first does not match but the second and third do match I get only the second. Why Don't I get the set of three?

Equation With Multiple Possible Results

Jul 30, 2011

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.

Convert String To Equation?

Apr 14, 2009

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.

VS 2010 - MouseMove Equation ?

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.

Concatenate A Equation And Answer To Text Box?

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.

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:

Display An Equation Prior To Solving It?

Jul 19, 2011

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.

Income Tax App - Adding Equation For Each Case

$7825-31852 = 15%income tax
$31851-77100 = 25%income tax
$77101-160850 =28%income tax
