Plotting A 2D Array Into A Chart Control As A Polynomial, VB 2010
May 17, 2012So I have a 2D array of data, specifically, one "Cv" value for every 10% increment. I have been able to get the Cv's plotted vs % open with the following method:
Private Sub btnPlot_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnPlot.Click
Dim tempString As String

I haven't yet looked into this, but if there's any way to also export this graph as an image into an excel spreadsheet, We will be creating several spec sheets as excel workbooks and we will need to be outputting standardized sheets, which is why I'm trying to make this an application instead of directly implementing the code in Excel with VBA.

VB Console App Calculator?
Oct 26, 2011I 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()

DIY Calculator : Keyboard Vs. Mouse?
Apr 30, 2010I am creating a DIY calculator.The one in W7, I can't hardly see. Mine is much simpler and larger.I currently have buttons for numeric 0 - 9, Add, Subtract, Multiply, Divide, Clear, Enter, and Decimal Point.There is a label at the top with displays results.If I use my mouse to select the buttons, then everything works okay. However, if I use the keyboard, I get strange results.I thought it may have been my old keyboard so I changed it.No difference.If it's not in the hardware, then it's in the code.The section below is what I have for keyboard use:
Private Sub Form1_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles Me.KeyPress
Ch = e.KeyChar
Select Case Ch[code]....
For each of these, there is a corresponding Button_Click even farther down in the code. Since the mouse click on the buttons on the form works properly, the problem must be above. I can't see it.
