Regular Expression Fails In IE, But Works In Chrome And Firefox?
Jul 13, 2010
I have the following asp.net markup:
<asp:TextBox ID="txtPassword" runat="server" TextMode="Password"
ValidationGroup="passwordValidation"></asp:TextBox>
<asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server" Display="Dynamic"
ControlToValidate="txtPassword" Text="Required" ValidationGroup="passwordValidation" />
<asp:RegularExpressionValidator runat="server" ControlToValidate="txtPassword"
Text="Passwords should contain a minimum of 7 characters with at least one numeric
character." ValidationExpression="^(?=.*d{1})(?=.*[a-zA-Z]{2}).{7,}$"
ValidationGroup="passwordValidation" Display="Dynamic"></asp:RegularExpressionValidator>
If I type in a password like test1234, it passes in chrome and firefox, but the message that my password should contain a minimum of 7 characters with at least one numeric character is shown in internet explorer
I have .net code that works on IE8 but wont work on google chrome or firefox. i have put this code for the user to press Enter instead of clicking the mouse everytime.
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load Try If Not IsPostBack Then
Ok so I'm not very familiar with Jquery as to know the possible cause of this, but I've been assigned to find out why the datepicker doesn't work porperly on a client's computer (it prints out the date without slashes like this: 24112008
So when I test the webform, I see it doesnt even pop up in Firefox (the client's browser too) nor chrome, only in IE8.
The following regular expression works in chrome and firefox, but not IE7:
^((?=.*d)(?=.*[a-z])(?=.*[A-Z]).{8,20})$
It needs to contain at least 8 characters and have at least on uppercase and a number. When I try this in IE7, I have to type 14 characters for it to validate. Can someone explain why and what would be the correct expression for all 3 browsers.
I am using an asp:RegularExpressionValidator to validate the password.
The following flash does not initially load in firefox, but if I click the second tab on the right, and then go back to the first, it loads. This works in Chrome and IE. Here is the webpage.
I'm trying to use the validator to work on a email form to ensure that they enter a valid from email address. That part works. I also want to add to the expression the text that I pre-populate in the txtbox ("Enter your email address") so on postback, after sending the message, I can clear the fields and repopulate that box.
How do I add that wording to the current expression: w+([-+.']w+)*@w+([-.]w+)*.w+([-.]w+)*
I am using Regular Expression validator for a text box. The below is working fine.It is not performing validation when I enter values like 0000..001.How can I modify validation expression? But it would allow values like 100,...5000 i.e zeros after a number.
<asp:RegularExpressionValidator ID="reg2" runat="server" ControlToValidate="rng2" ValidationExpression="^[0-9]+" ErrorMessage="*Please Enter a Valid Number for Second Range." ForeColor="Red" Font-Bold="True"></asp:RegularExpressionValidator>
I need some help in regular expression.I am validating the textbox text when updating the records.When i click the update button,the first 5 letters should be equal to CM000 or cm000.How to validate this using regular expression in asp.net. does anyone know validationexpression for this.
I've created a new website using forms authentication. Everything works fine on my local DEV machine - I can log in with no problem in any browser.
But as soon as I deploy this to my production server, I am unable to login using IE. I get to the login page and when I click to login, it just reloads that page and never authenticates me. If I use Google Chrome, I can log in without any problems.
I know this sounds similar to the common problem where you don't have your applicationName specified in the web.config file, but I have that specified in all of my providers.
I've tried this in both IE8 and IE9 while adjusting the cookie settings to accept everything and it makes no difference. I've also tried on multiple computers.
Since I can get it to work in Chrome, I feel like there must be a setting in the code somewhere that affects IE differently. I have a hard time believing it's a setting in IE because I use the standard, default setup there.
The only way I could get this close to working was to adjust this forms authentication setting: cookieless = "UseUri". When I did this, I could get past the login screen to my default page, but then when I tried to navigate to any other pages, it would always take me back to the login page and make me login again. It would take me to the requested page each time, but I would still have to login again at every new page request.
Here are a couple of snippets from my web.config file.
i have this code in global.asax.vb, to disable the back button.
Sub Application_BeginRequest(ByVal sender As Object, ByVal e As EventArgs) Response.Buffer = True Response.ExpiresAbsolute = Now().Subtract(New TimeSpan(1, 0, 0, 0)) Response.Expires = -1 Response.CacheControl = "no-cache" End Sub
this code works perfect in IE, but refuses to work in any other browser like firefox or chrome. what can i do to make it multi browser?
I'm doing css for a website. I send the html and css to a guy, he puts it into ASP.net. The problem is that the transfer didn't end well for my code and it needs some fixing. The problem is that when I look at it in Chrome, or Firefox, or IE8, I get three completely different renderings. I spent a good amount of time trying to fix a drop-down menu that is supposed to appear while hovering over a link. The one he had in place from ASP.net worked in IE, kinda worked in Firefox, and was completely broken in Chrome (I haven't tested Safari or Opera.) Just getting it to look basically the same in firefox and chrome was a struggle. The html source is showing me two completely different pages as well.
Does anyone have experience with this? I know nothing of ASP.net, and it seems like the guy is modifying my layout with a wsyiwyg (I found tables used in random places, which I did not put there.) Faced with this, what is my best option? Is this fixable, or am I in over my head?
I use Response.BinaryWrite to display this picture.
Unfortunately it works only in Internet Explorer. In Firefox and Chrome it shows long text of strange symbols.
What's wrong with BinaryWrite? How to solve this?
I may not say to asp:Image to show this picture, I may not indicate ImageURL, becouse there's no URL. This picture is response from webrequest. And webrequest may not be indicated in URL because I set some parameters not in QueryString but in post data.
I have an interesting issue. I made some changes to an existing code base. The changes were fairly minor in the aspect of the pages, I added an UpdatePanel and some input areas to upload a file and update a database to the site master. The reason I add it to the site master was it is being called to display via jQuery. I made some additional code changes on some existing code behind to add a web method to handle the data from another jQuery driven piece to set a value for a particular billing code.
None of this is out of the ordinary and in fact it only adds additional similar functionality that I have added over the last 9 months. The issue now is since I made the changes using the browser back button in IE generates the following:
Webpage has expired
This only occurs with IE. Chrome and FireFox works fine. Thinking it maybe the new input boxes I removed those and attempted to run the application again I get the same result. I know that IE requires a refresh if there is data that is submitted on the form that you are trying to go back to, however so does Chrome and Firefox as far as I know.
I found the answer to this, but it's a bit of a gotcha so I wanted to share it here.
I have a regular expression that validates passwords. They should be 7 to 60 characters with at least one numeric and one alpha character. Pretty standard. I used positive lookaheads (the (?= operator) to implement it:
(?=^.{7,60}$)(?=.*[0-9].*)(?=.*[a-zA-Z].*)
I checked this expression in my unit tests using Regex.IsMatch(), and it worked fine. However, when I use it in a RegularExpressionValidator, it always fails.
I've created code to retrieve an image from the file system using an ASHX handler. The code displays the image correctly in Chrome, but I get a broken image in IE:
I've built this app that displays employee photos stored in several sharepoint folders. It also displays the employee name extracted from the file name and a previous and next button to move through the photos.
The markup is surrounded by an update panel to prevent the entire page from reloading when you click to view the next photo.
The app is working fine in firefox, but the images do not display in IE8. Can anyone tell what is causing this?
public List<string> photoFileList = new List<string>(); protected void Page_Load(object sender, EventArgs e) { if (!IsPostBack) { Session["index"] = 0;
I developed a activex control, it can work well in IE, but not in firefox , is it possible for my activex control to work in FireFox and Google Chrome?
I want to open a popupwindow (with close button only) when the user clicks a button and the parent window should be disabled until the popup window closed. For that I'm using the following code
function popup_window(url) { popupwin = window.showModalDialog(url,null,'height=20,width=150,status=no,resizable=no,scrollbars=no,toolbar=no,location=no,menubar=no'); }
Anyhow, this code is working perfectly in IE. But, I hav two problems. In firefox, it is not opening with the size I've mentioned in the script. It is opening in full size. And In Google Chrome, parent window is not getting disabled.
I was trying to prototype some jQuery-based menu into ASP.NET MVC. Just to name two examples here: [URL]Their demo page looks great, but when I integrate their sample code into MVC, the script no longer works in IE and FireFox, but it seems to work just fine under Google Chrome. Can someone kindly enough to point out what I missed? I will be honest here. I am still new to JavaScript. I have placed a copy of my VS2010 solution zip file @ [URL] Here is what I did. In the Site.Master, I have something like
Compiled the code and ran it under IE. Ideally, it should work like the demo in [URL], but in reality, it only displays unordered list in plain view. (If you download the solution file and run it, you should be able to repro this as well). Next, tried with FireFox, not working either, same result as IE. Finally, when I try it under Google Chrome 4.1 (lastest version), and the script displays just fine.
