I'm currently creating a maths game for primary school children and have questions based on addition, subtraction, division and multiplication.I tried it out yesterday and if I type in the correct answer, I get told it's wrong, but if I type in the in the number I'm dividing by, as the answer it comes up as correct. How do I change this so that the correct answer is actually the correct answer?

NumberDecimalSeparator Is Giving The Wrong Answer?

Oct 16, 2009

I've got this code to get the decimal and groupseparator settings on a computer:

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim NumFormat As New System.Globalization.NumberFormatInfo

[Code]....

The problem is that on my computer NumberDecimalSeparator should return "," and NumberGroupSeparator should return ".", but it's just the other way around when I try to get both separators from my system. What could be going wrong, and even more important, how to get the right strings? I did check my locale setting to make sure I'm not crazy and I also didn't switch the textboxes.

Quiz Program - Asking Five Questions With Yes Or No Answer

Mar 19, 2009

I'm trying to make a quiz application with Visual Basic at the moment. I want to write a routine that asks five questions to which the answer must be either Yes or No. It must add up the number of Nos and if the number of Ns is less than two then print out "pessimist", otherwise print out "optimist". So far this is the design of what I've done. [URL]. However, I have no code which I've produced on my own.

Code:
Public Class Form1
Inherits System.Windows.Forms.Form
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
End Sub
End Class

I really don't know how I can kind of add up all the results from each individual question, seeing as radio buttons are used.

Making A Messenger - Program A Slight Delay In The Computer's Answer?

Jan 15, 2010

I'm working on a project where I make a automatic messenger from VBnet. I want to program a simple one that responds to certain words or phrases. However, I only know the rough basics of If...Then commands. I have a lot of problems:

1. How do I make it so the messages typed in the box actually goes up into the script box when I press send?

2. How do I program a slight delay in the computer's answer?

3. How do I set a name to the computer and to me?

4. How do I make the script goes into scrolling when it runs out of space.

5. If possible, when I type an equation in the box, can I program the computer to solve it and display the answer? I'm a beginner so I don't really know the overall organization of this project. However, I would like it to remain as simple as possible.

Datagridview - Remove Wrong Columns And Display The Wrong Data

Jan 12, 2010

I've got a DataGridview I want to remove columns from as it greatly increases performance when I format the DGV. The first time I remove columns in a loop (using the removeat) property, everythings fine. But when I try to remove more columns in another loop, it appears to remove the wrong columns and displays the wrong data. In other words, it displays the wrong data and headers; and the columns it does show has headers and cells that don't match.

Calculating Value And Showing Answer In Label?

Jan 24, 2012

I have several buttons in my form and they each need to add, subtract, divide and multiply certain values together but I seem to be having problems with this. I didn't expect anything to go wrong and its probably a rookie mistake, but take my first calculation for example; a user must enter a value in a textbox (txtDays) and and also when one of my various radio buttons are pressed a value shows in a label (lblDailyHireCharge). I now need a way of multiplying these values to give me my answer shown in a label. I have done this by adding a button when which pressed multiplies the txtDays value with the lblDailyHireCharge and then shows it in the label, however it keeps on showing "0" when i click it.

Below is my code, I am basically saying that the value of both of those figures is intDuration and that lblDuration is where I want it to go when the button is clicked.
Private Sub btnDuration_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnDuration.Click
Dim intdays As Integer
Dim intDailyHireCharge As Integer
Dim intDuration As Integer

Concatenate A Equation And Answer To Text Box?

Mar 22, 2011

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?
