Sometimes you only want to enter numeric data in a textbox. You have two options here : Let a user type whatever he/she wants into a textbox, validate the input and show him or her an annoying message that he/she has done something wrong.:angry: Or: capture the key before input, check if it's "numeric" and allow only "numerics" to come through. That way, you know the input is correct and you can proceed.:) A decimal point should be correct input, but only once. The next snippet does this and is easily adapted to allow for sientific input(+,-,e,E)

Hi All, I have an online screen in which a form filed is filled with Numeric Characters .. if the entered four digits are not numeric, it will throw an alert message saying "**Only numerics allowed**". Now the new requirement is it should accept alphanumeric characeters instead of Numeric Characters. Below is the code which is used to check the value. if (vic.value.length != 4 || !isInteger(vic.value)) { alert ("VIC is required (4 numeric digits)."); return false; } How do i change this condition to check for Alpha Numeric Characters instead of Numeric. Thanks in Advance

I have this line of code: $str = "$str<td><a href=\"javascript:Open($Row->ID , $Row->IDCode)\" title=\"click to open window...\">more...</a></td></tr>"; it works fine when the IDCode at the $Row->IDCode is a numeric but then it doesn't work anymore when the IDCode starts with a character. At my database the ID is int(11) unsigned and the IDCode is varchar(10).... the javascript for this is: function Open(susi,kodigo) { if (susi) { Win = window.open("View.php?View=" + susi + "|" + kodigo , "winMore", "height=480, width=450, resizable=yes, scrollbars=yes, top=100, left=125"); } } ...it's not clear to me why it doesn't work on characters.... please help...thank you in advance...

This module is for validating textboxes.... After using this module in your project you can simply validate all of your text boxes like [CODE] Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load AssignValidation(Me.TextBox1, ValidationType.Only_Digits) AssignValidation(Me.TextBox2, ValidationType.Only_Characters) AssignValidation(Me.TextBox3, ValidationType.No_Blank) AssignValidation(Me.TextBox4, ValidationType.Only_Email) End Sub [/CODE]

I'm having trouble with validating my textbox. My textbox should only accept decimal number, and should not accept negative number. i tried this code for validating the input type, but i fail. [CODE]If Not Char.IsDigit(numWeight.Text) Then MsgBox("Incorrect input.") End If[/CODE] And i don't know if this is the right code for validating for negative numbers. [CODE] If numWeight.Text.StartsWith("-") Then MsgBox("Invalid weight.") numWeight.Clear() End If[/CODE] Please guys need help. Thank you, and God bless.

Hi everyone! I'm a student taking an introduction to Python programming class and I'm in URGENT need of some help! Basically the program I need is to compute the "numeric value" of a name. Ex. a = 1, b = 2, c = 3, etc. So name abc = 6. I'm to capitalize the name before I compute the letters also. I should mention that the program can't be too complicated yet because we're only on chapter 4 of this book :[url]http://www.amazon.com/Python-Programming-Introduction-Computer-Science/dp/1887902996[/url] I'm not sure if it has anything to do with splitting the name as a string.
