Taking Numbers From Inputbox To Textbox?

Mar 11, 2010

I am trying to write a program that is a statistical calculator. The way i have it set up is that you press the enter data button and it asks you how many numbers you want entered by inputbox then it proceeds to take the numbers one by one by inputbox. The problem i am having is that i dont know how to take these numbers and then have then printed in the "input" textbox. I have attached a pic of my program to give you some idea of what im talking about.

N = InputBox("How many numbers need entered:")

Textfields Only Accept Numbers?

Feb 24, 2010

I have an application where a user is entering data into textfields using vb.net and then it is saving to excel. The textfields only accept numbers and do not allow the user to proceed unless all textfields have been filled out. If for some reason the user cannot enter in data (machine being broken etc...) is there a way that a messgagebox with a textfield can pop up allowing them to enter the reason that they couldn't enter a reading and then get saved to a textfile or sent as an email.

Textbox - Text Box To Only Accept Numbers?

Apr 2, 2012

I'm fairly new to VB.net (self taught) and was just wondering if someone out there could help me out with some code. I'm not trying to do anything to invovled, just have a textbox that takes numeric value from 1 to 10. I don't want it to take a string or any number above 10. If some types a word or character an error message will appear, telling them to enter a valid number. This is what I have, obviously it's not great as I am having problems.

Create A Text Box That Will Accept Numbers In The Currency Format?

Aug 2, 2009

I need to create a control for input a currecncies to a field. I'm planning to use a Textbox.

This is the format of the text box for currencies:

"XXXXXXXX.XX"

the dot "." must be fixed in the textbox and it should be loaded with the textbox. Furthermroe i have plans to code eachtime a user enters a number it should print the numbers from Right ot left.

eg: When user enters Number 1234.34

When the user enter these number they should display them as:

when user enters 1

0000.01

when the user enters 2:

0000.12

when the user enter 3:0001.23

When the user enters 4:

0012.34

When the user enters 3:0123.43

When the user enters 4:(after entering all digits in the number)1234.34

Could any one give a couple of ideas how to creat these kind of boxes?

I was thinking about creating a custom control (a Textbox) but still i need to have a the above format in the textbox!

TextRate Control Should Accept Only Numbers / Period And Backscape Key

Oct 16, 2011

I'm beating my head against the desk on an advanced level solution in the VB 2010 book, and can't figure out what I am doing wrong. This is the exercise: JM Sales employs 8 salespeople. The sales manager wants an application that allows him to enter a bonus rate. The application should use the rate, along with the 8 salespeople, in an array, to calculate each salesperson's bonus amount. The application should display each salesperson's number (1 through 8) and bonus amount. as well as the total bonus paid, in the interface.

1. The txtRate control should accept only numbers, the period, and the Backscape key.

2. A one-dimensional array should be used that has elements initialized to the following sales amounts: 2400, 1500, 1600, 2790, 1000, 6300, 1300 and 2700.

I have the interface created and its error free (for now) but its not doing what its supposed to do. It's supposed to show something like this. I can provide screenshots if necessary. [code] but what I get is a list of 0.00's in all of the above fields. What am I doing wrong? Heres the code finally, sorry if I was overly descriptive. This is my first time doing one of the advanced exercises, maybe I should go back to intermediate.

FLAG And InputBox - Display An InputBox For Each Word?

Jun 22, 2010

I have an assignment that asks me to:

1. create a button
2. when that button is clicked, an inputBox will appear to ask the user how many words they will enter.
3. then display an inputBox for each word.

For example, when the first inputBox appears, I enter "3" (meaning that I will enter 3 words).Then there should be 3 more inputBox (each inputBox allows me to enter only 1 word)After I enter the third word, there will be no more inputBox.How can we FLAG (stop) the inputBox, or let the inputBox know when to stop showing up?

Forms :: Break Down Numbers Program?

Sep 8, 2009

I am currently writing a program that when a user enters a number such as 1267 and clicks a button the number will then be
broken down by its ones place, tens place, and so on. So it would show up as One place is: 7, Tens place is: 6, and so on.Well I need a little help trying to figure out what code I would write to test or separate each single integer. So far I have only been able to separate the ones place using:

Dim ones As Integer = Microsoft.VisualBasic.Right(TextBox1.Text, 1)
'display each value in the corresponding place
Label11.Text = ones

of course this code wouldnt work for the rest of the digits entered.If a user were to enter a bigger number lets say:

12345

then i would need to display

thousands place is: 12
hundreds place is: 3 and so on and so on
