Validation Controls for Windows Forms (VB.NET) The Windows Forms ErrorProvider component is used to validate user input on a form or control. It is typically used in conjunction with validating user input on a form, or displaying errors within a dataset. An error provider is a better alternative than displaying an error message in a message box, because once a message box is dismissed, the error m
MaskedTextBox Control in VB.NET MaskedTextBoxes can be thought as the extension of MaskedEdit Control of VB6.0. It can be used to validate TextBox input based on ‘Mask’ The MaskedTextBox class is an enhanced TextBox control that supports a declarative syntax for accepting or rejecting user input. Using the Mask property, you can specify the following input without writing any custom va
If your blog or website looks good in IE does not mean that it will also look good on other browser platforms. Different browser reacts in a different way. The header part which is looking good in IE6 may not be visible in safari, ubuntu, Mac OS, opera or Firefox or on any other browser. You need to make sure that your blog looks good across the entire popular browser platform because different r

Detect errors in email addresses using .NET exception handling There are n-number of ways to detect errors in email addresses; some use regular expressions to do that. The same has been built as a check in ASP.NET validation controls. The following function uses the Try-Catch exception handling by assigning the address to the mail message. If the format of the email address is found to be wrong, then the function returns false. A simple one; please post your comments on the way it worksJ Function Detect_MailAddress_Errors(ByVal sMailAdd As String) As Boolean Try Dim oMailMsg As New MailMessage oMailMsg.To.Add(sMailAdd) Return True 'Format Exceptions Catch exFormat As FormatException 'MsgBox("F
This is just a small VB code to validate credit cards number, all credit cards work with this algorthm;
If the number is in a valid format if returns 'True'.
If the number is in an invalid format it returns 'False'.
If a card validates with this code it doesn't mean that the card is actually good, it just means that the numbers are arranged in a valid format.
If they don't validate then
Argonne's testing shows that the Hydrogen 7's 12-cylinder engine actually shows emissions levels that, for certain components, are cleaner than the ambient air that comes into the car's engine.

Researchers at the University of California, San Francisco have developed a way to quickly estimate a woman's risk for invasive breast cancer. The new model, based on a measure of breast density that is already reported with the majority of mammograms today, is the first to be validated across multiple ethnic groups living in the United States.
The model could one day be used to help calculate a
If you are looking for the validation of a number which contains only two decimal places. Means you want to accept the values like 0.21 or 1.34 or 12.55 or 445.66 as a input and throw an error when somebody enters the number like 0.2 or 4.678 from a text box. Here is a simple [...]
Back in the early 90's, as the internet was being shaped and HTML was still a foreign acronym to most, a "standards" organization known as the World Wide Web Consortium (W3C) was formed. The purpose of the W3C was to develop certain standards for HTML to follow. This was vitally important because different vendors had begun creating their own versions of HTML with their own features. So the W3C worked to get all these vendors to agree on supporting the same set of components and principles. Fast forward to today -- the W3C is still setting standards for website coding, and although most sites do not conform completely to their standards, most follow them to some degree or another.Now I'm a pragmatist and contrarian. In the past, when web designers/developers touted the necessity of validating website code to W3C standards, I would resist. I would claim that it didn't matter as long as your website simply worked with all the major browsers. Besides, I reasoned, why spend all the extr

Hy! Today we learn how to validate HTML and CSS from your page. This tip is usefull if you have a website about webdesign where you have tools for development! Here is the final result
with a design what i made, you have all files in the archive HERE. Let’s Start.
[1] Open your text editor and type the next HTML code
<html>
<head>
<title>Validate CSS, HTML, XHTML from your page</title>
</head>
<body>
<div>
<form method=”get” action=”http://jigsaw.w3.org/css-validator/validator” target=”_blank”>

Sometimes we need to validate an input from client browser before we push the value into further proccess, here i share 3 simple functions to perform validation input from forms and or querrystrings
Validate Integer Value Using isNumeric function
function isNumeric($n){
return ( $n == strval(intval($n)) )? true : false;
}
the simple php function above will perform an integer validation input, the proccess is pretty simple, the if control structure will evaluate whether the argument value ($n) has the same type with itself after cast to integer (strval(intval($n))), the right part of if expression (strval(intval($n))) is a simple way to cast any type of variable into integer. Sample of usage:
echo ‘<br />isNumeric(1) = ‘.(string)isNumeric(1);
echo ‘<br />isNumeric("a") = ‘.(string)isNumeric(‘a’);
echo ‘<br />isNumeric(0.1) = ‘.(string)isNumeric(0.1);
Validate Float Value Using isFloat function
function isFl
Validate your forms with javascript to make it easier for the user and reduce server load. The php class generates the javascript automatically and it also has a fallback to php validation if javascript is not available. It works with both php4 and php5.
Few days ago I wrote SQL SERVER - UDF - Validate Integer Function. It was very interesting to write this and developers at my company started to use it. One Jr. DBA modified this function to validate only positive integers. I will share this with everybody who are interested in similar functionality.
Code:
CREATE FUNCTION [dbo].[udf_IsNatural]
(
@Number VARCHAR(100)
)
RETURNS BIT
BEGIN
DECLARE @Ret BIT
IF (PATINDEX('%[^0-9-]%', @Number) = 0
AND CHARINDEX('-', @Number) <= 1
AND @Number NOT IN ('.', '-', '+', '^')
AND LEN(@Number)>0
AND @Number NOT LIKE '%-%')
SET @Ret = 1
ELSE
SET @Ret = 0
RETURN @Ret
END
GO
Example:
SELECT '999' TestValue,dbo.udf_IsNumeric('999') NumericTest;
SELECT '-999' TestValue,dbo.udf_IsNumeric('-999') NumericTest;
SELECT 'abc' TestValue,dbo.udf_IsNumeric('abc') NumericTest;
SELECT '9+9' TestValue,dbo.udf_IsNumeric('9+9') NumericTest;
SELECT '$9.9' TestValue,dbo.udf_IsNumeric('$9.9') NumericTest;
SELECT 'SQLAuthority' Tes
Performance and load testing is often viewed as something that has to be done late in the development cycle with a goal of validating that performance meets predefined requirements. The problem with this is that fixing performance problems can require major changes to the architecture of a system. When we do performance testing last, it is often too late or too expensive to fix anything.The truth is that performance testing does not need to happen last. Load test scripting is often easier if we wait until the end, but should we sacrifice quality just to make testing easier?Scott Barber divides performance testing requirements and goals into the following three categories:Scalability -- extremely technicalStability -- mostly technicalSpeed -- fuzzy: some technical, other usabilitySpeed is where things get fuzzy. Some speed requirements are quite definable, quantifiable and technical; others are not.- Scott BarberScott says that hard measurable requirements can usually be defined for sca

CHICAGO – This is why wrestlers wrestle and actors act. Vinnie Jones (left) and Steve Austin in “The Condemned”.Photo courtesy of Vince Valitutti“The Condemned” tobogganed downhill the second it splashed the WWE on an introductory screen. Sure, you know the WWF, but you may be learning for the first time about World Wrestling Entertainment, Inc.It’s a publicly traded sports entertainment company. While one of its cash cows is film, this particular film could be more like a cash hog after it opens on April 27. I’m not sold that the WWE should be in the business of film at all.In fact, it reminded me of “yellow journalism,” which is a pejorative phrase coined for overtly scandalous and sensational journalism. “The Condemned” could be considered “yellow film”.Senseless and gratuitous violence can be a titillating thrill ride when it’s not just gore for gore’s sake and the message is meritorious. The film “300” almost makes gore feel beautiful while “Gri
I wrote about it here and it is really usefull. As we now the embed code of youtube is a mess as it uses the embed tag which does not validate as xhtml. Using the code this tip you can embed a youtube or google video to your site or blog and keep your code validated:<object type="application/x-shockwave-flash" data="http://www.youtube.com/v/moviecode" width="400" height="326"><param name="movie" value="http://www.youtube.com/v/moviecode" /></object>The moviecode is a code found in each youtube video adress and is after v= until the first ampersand (&). For example in this URL http://www.youtube.com/watch?v=xmHHjUZPyMY, the code is xmHHjUZPyMY.

It's good to validate maximum length of a textbox's content. There're many ways for doing that. In our oppinion best way for doing that is with Regular Expression:
