Textbox - Text Box To Only Accept Numbers?
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.

View 7 RepliesCreate A Text Box That Will Accept Numbers In The Currency Format?
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:
"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!
Textfields Only Accept Numbers?
Feb 24, 2010I 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.

View 5 RepliesTextRate 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.

Box - Conversion Error - User Enters 6 Numbers In 6 Different Text Boxes - Displays The Larger Of Those 6 Numbers
Oct 4, 2011I am making a program, where the user enters 6 numbers in 6 different text boxes, and it displays the larger of those 6 numbers. But I also want to make it where if the user enters a string value (like S for instance) in the text boxes, it gives an message and says "please enter the numbers again" and the user gets to enter the 6 numbers again. But when I do try to do that, it gives an error message saying conversion from "w/e the user entered" to Double is not valid. If the user just enters the numbers, it works fine. However, I am trying to make it if the user does enter non numeric value, it gives a message window and the user can reenter the numbers again.
Here is my code Example
CODE:
This is where I am trying to use IsNumeric to show a message if a user does not enter a string so the user can renter the numbers again, but when the user does enter a string value (say in textbox 1) it gives me an error message saying conversion from "S" to 'double' is not valid.
CODE:
Then right here this is where I have my series of ifs statements, this part works fine, it displays the largest numbers of the 6 textboxes every time. Error free.
CODE:
And do this with variable number 2, 3, 4, 5.
I know there are easier ways to do these with arrays and stuff. But I am not there yet. I am still learning about ifs and stuff.
