Apr 2, 2012I'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.

Aug 2, 2009I 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:

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, 2011I'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.
