View 1 RepliesI have a form where a user is going to enter an email address. What is the best way to validate what they enter? Whether it's okay to throw an exception to validate input versus using a regex?
[URL] ....
Specifically: Don't bother with your own validation. .NET 4.0 has significantly improved validation via the MailAddress class. Just use MailAddress address = new MailAddress(input) and if it throws, it's not valid ...
And the counter argument: it is generally bad practice to catch an exception as a way of validating data ...
<asp:RangeValidator ID="RangeValidator1" runat="server" Display="static" ControlToValidate="txtcpwd"
ErrorMessage="Password must be minimum 6 & max 8 characters" Type="String" MinimumValue="6"
MaximumValue="8" Visible="false">
Even if I have minimum 6 characters its still displaying the message.
I wanted to write a regular expression using the ASP.Net RegExp validator that would ensure a field contains only numeric and decimal values, and at least one character.
^[0-9]{1,40}(.[0-9]{1,2})?$
Essentially: [0-9]{1,40} - meaning at least one to 40 numeric characters.The ASP.Net regexp validator does not fire for an empty field - where there is not at least one character.

I have a page in MVC where i want to take the email adddress as the input which can be of format like:"Jone Davi" <jone@gmail.com>, "Ben Miller" <ben@gmail.com>, "Jane Ton" <jane@gmail.com>,
Then from this I want to parse the valid emailaddress.But on click of the submit button getting error message" A potentially dangerous Request.Form value was detected from the client" Thus is there any way to take the input of email address in above format and bypass the security error for that specific page.
how do I grab an email address from a web form and email to that email address with the link to a webform?
View 5 RepliesI have a regular expression validation control initialized to validate a textbox control. I want users to be able to enter U.S. Currency values ($12,115.85 or 1500.22 etc.). I found a regular expression off of regexlib website that does the trick. The validation control seems to be working except for one crucial thing. If invalid data is entered, the validation text dispalys (a red "*" next to the textbox), but the page will still submit and the error message won't pop up... I thought that the error message is supposed to display and the page won't submit if the validation control detects invalid data. Isn't this automatic with ASP .NET? I have searched extensively on how to create validation controls, but haven't found anything different than what I am already doing. Can anyone tell me what I am doing wrong here?
<asp:TextBox ID="txtActualCost" runat="server" Width="120px" CausesValidation="true"></asp:TextBox>
<asp:RegularExpressionValidator ID="regExValActualCost"
ControlToValidate="txtActualCost"

View 1 RepliesIn addition to the process of regex syntax validation of Email Addresses entered by users, I'm trying to check if the entered email address is a real one and does exist?The best I could achieve is to "Ping" the host the email address is associated with. But there are some other terms in the industry like Handshaking with Email Server, etc.not necessarily with 100% confirmation accurary!

View 1 Replies have code on a web form -- when you hit the button "send emails", it executes this sub which reads an SQL database table and sends emails one by one -- however I get this error above -- anyway to check it and skip to the next email? Some emails in my table have name@test.co.il for example, so it seems this causes this error.

I have a form that contains several textboxes and each one paired with a required validator. Each box reads a value from a dataset, and on submit click, update the database with the new value. For some reason, one of the validator always returns the error message even if I enter a value in the textbox. My code is something like this.
