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.
I have this:
If (TextBox1.TextLength > 16) Then Return
But I want to add a beep to how can I do it? I mean I can only Return and I want to use Beep() too.
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:

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 creating a backspace key for a calculator. first of all a currency needs to be chosen by clicking a button, when for example the is clicked the text is entered into the texbox. But when i use the backspace it deletes here is my code..

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]

I basically want the user to be able to enter an equation like SQRT(5 * 6) / (2 ^ 4) and then I want vb to use system.math to solve it. If I write this in my code, vb is able to do it, so how could I do this at runtime.

I 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.
