Write A Program That Allows User Input Information?

Jan 30, 2012

I am trying to write a program that allows user input information and plot a bifurcation diagram that looks like this:I haven't program in 2 years:sick: so I am all rusty and such. Here is what I have got so far and more information about what I am doing.

Bifurcation:
f(x) = kx(1-x)
and k = xL + i * (xR-xL) / 500

when i runs from 0 to 500, it plots (i, f(seed)), (i, f(f(seed)), .... up to the boundary number.Here is what I have got so far. Everything seems normal, however, I am really confused when it comes to plotting.

Write A Program To Request Positive Numbers One At A Time From The User In An Input Dialog Box

May 12, 2009

I'm currently in VB class at my highschool and we just got chapter 6.1 to read on this online textbook that we follow. Anyway, we are doing loops now and the problem reads "Write a program to request positive numbers one at a time from the user in an input dialog box. The user should be instructed to enter -1 after all the positive numbers have been supplied. At that time, the program should display the sum of the numbers." So far I know this much

[Code]...

Now I know this isn't right But I can't find out how I'd pull out the numbers the user entered to get the sum of them and not include -1 because as it stands, when I hit ENTER with -1 the label just shows -1.

Jan 21, 2010

I am new to VB.Net and programming all together. I am trying to make a program that will take 2 numbers input by the user, Add them together and display the sum. Then take the sum and divide it individually by each number to give you what percent of the sum the numbers are.

So.. Here is my code so far. It's not complete yet but this is should be enough to make it function.

Program Not Updating Screen - No Response To User Input

Jan 2, 2012

I have a program written in VB 2010 express under windows xp which does some heavy number crunching combined with serial communication. When it "gets too busy" it does not update the screen anymore (done simply with Textbox.text = "any text") and it does not respond to user input in any text box. Not even to a click on any text box. Is there a way I can get the program to do screen update and respond to user input while it is busy?

Handle Errors Caused By Invalid User Input In A Program?

Mar 10, 2011

how do I handle the errors that may appear from the user of my program. For example, I have an triangle area program in wich I ask the user of the program to insert the length of the base and height of the triangle in a textbox. But what if he inserts a letter or something else, like a sign....my program will crash...

I know that one method would be to use On Error GoTo but I don't know how. If maybe you can direct me to some link or you could explain how do I handle errors, I would be grateful. Maybe you can even show me other ways to avoid errors from the user input.

This is my small program so far:

Private Sub Button1_Click(ByVal sender As Object, ByVal e As EventArgs)
Handles Button1.Click
Dim , Height, ARIA As Integer
