View 9 RepliesInput Numbers Into Selected Textbox?
Feb 28, 2010I have 10 buttons 0-9 And i have 4 textboxes All representing different values (n,e,x,y) Ok so what i want is to be able to use my 0-9 buttons to input the numbers into the boxes. However my problem is How can my program know which text box the mouse cursor is in. Right now, i can only get it to go in one of the boxes That i tell it too by using the textbox's name. Or all of them at once.
SO is there a way that when i click in text box "n" when i click numbers they will go there. Then if i click in text box "e" and click the the numbers, they will go in there?

Inputting Numbers Into A Textbox And Formating The Numbers?
Jul 30, 2009I just D/L VB express 8, and I'm trying to learn how to use it. what I'm trying to do is write some code that:takes a number into a text box (textbox1.text)do some simple calculations with that number when I press a button (button1)display the results in a second text box 9textbox2.textThe first problem I am having:The numbers are in the "milli" range, meaning to the power of negative three, so 10^-3 = 0.01 I do not want to enter 10^-3 or any other exponent into the textbox, I am simply entering in 10 because all my units will be in milli. I've tried using exponent and scientific notation but it doesn't calculate correctly. I've done a "work around" to get it to do what I want, but there has to be a simpler way to achieve the above results without. for example, the user enters 10 into the textbox, the button multiplies 10^-3 *30, as a crude example, and stroes that value (say, B=10^-3*30) and B is DIM B as Double.
Problem number two:Error checking. I need to validate that only numbers can be entered into the textbox, or else the program will display an error message (messagebox). I can achieve this to some degree with sample code from here and other places, but, some of the code does not take into account that some numbers have decimal places (I have foud code that does, and it does work), but if a users enters, say the letter "E", it crashes the program. If the user enters "10.3Z", it crashes the program. I cannot seem to code for the last case, a mixture of numbers and letters to get an error message box.

Display All Even And Odd Integers Between 2 User Input Numbers?
Mar 23, 2009using for...next loop the program is supposed to accept 2 user inputed integers and display all even numbers between the two in one label and all odd numbers between in another label.
Private Sub displayButton_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles displayButton.Click
' displays the odd and even numbers between two integers
Dim intNum1 As Integer

I'm not exactly sure what this code is doing. When I put 1 in the first number and 10 in the second number, the odd label only shows 9 and the even label only shows 10. Another example is when I put 2 and 15, the odd label comes out as 15 and the even label is 14. I'm very new to VB and programming in general and have just started getting into for...next loops and don't fully understand what the counter is or how the loop is supposed to work. I guess I'm having 2 problems. One is that I don't know how to make the program find the right numbers(my logic is off? or how I set up the loop isn't right?) and the other is the labels are showing only 1 number each instead of all the numbers in between on their own line.

Standard Deviation Calculator - Random Number Of Numbers Input By User
Feb 19, 2011Im working on writing a program for doing standard deviation and as of right now im running into one slight issue with subtracting my mean from the original numbers. I will post most of my code so you can get an over view but i mostly just want help on this one little part for now. Im going to be making a website for school and put some programming stuff on it so i wanted to make just some random programs for it so this is school related but not really homework. It's line 26 and 27 that this is relating to. When i put a stop in my code and look at the result of arrayDifferences it gives me 0.0 when it should be -1. I know i can go this route and say arrayDifferences(1) = arrayDifferences(1) - arrayAvg but seeing as how i want this to be a random number of numbers input by the user i cant do that.
