• How to check if user submit Arabic words from a form?

  - by ronanray

  Hi Experts.. Is there any reliable way to check if user has entered Arabic words into a form and tries to submit it? Can Javascript handle this? Or, only server script like .NET can do this? I'm thinking that if possible the script should directly prevent the user from inputting Arabic words into the form and show an alert pop up. Please share any examples if you have any idea how to do it. Thanks

  you have a class A, where you set ctor to be private, so a client can't call "A a;" to create obj on stack. But someday another developer add a new ctor: "A(int)" and try to call "A a(1);" inside main(). So this will create a obj on stack. How do you prevent that?

• How do I deny access to invalid web subdomains with .htaccess?

  - by Gravitas

  The following .htaccess file does not work: SSLrequireSSL RewriteEngine on RewriteCond %{HTTP_HOST} !^secure\.neuralfutures\.com [NC] RewriteRule (.*) - [F] I'm trying to prevent access to anything but "https://secure.neuralfutures.com/docs/", i.e. "https://www.neuralfutures.com/docs/" will fail. I also seem to be running into caching issues: if I upload the new .htaccess with CuteFTP, then do a file refresh in FireFox, it doesn't seem to have any effect on the output at all. I can tell this because if I comment out SSLrequireSSL, it still disallows a http:// request.

• Exchange server actively refuses my connection

  - by Roy

  I'm writing a ASP.NET application used within our company. Now I want to send emails to some users via a email account on our exchange server. I tried to use System.Net.Mail.SmtpClient, where a proprietary account and password are given to specify the credentials. But the code failed with following exception: "No connection could be made because the target machine actively refused it" Is that due to Exchange Server policies to prevent spam? How can I get it to work?

• Best way to enter numeric values with decimal points?

  - by Andrew Grant

  In my app users need to be able to enter numeric values with decimal places. The iPhone doesn't provides a keyboard that's specific for this purpose - only a number pad and a keyboard with numbers and symbols. Is there an easy way to use the latter and prevent any non-numeric input from being entered without having to regex the final result? Thanks!

  I'm putting together a site that will make itself available for user input. I was wondering if writing a function like: if(getenv("HTTP_REFERER") != 'http://www.myURL.com/submitArea'){ die('don\'t be an jerk, ruin your own site'); }else{ // continue with form processing } is enough to prevent cross site form submissions.

• LaTeX not compiling properly

  - by celenius

  I'm using TeXshop, Natbib, Hyperef and two-column layout, and I am getting the following message: \pdfendlink ended up in different nesting level than \pdfstartlink which prevents LaTeX from compiling. I've searched online for solutions, but most of them are from a few years back, and I don't understand them. Is there anything I should be doing to prevent this error? It appears to be happening due to where the pagebreaks are occurring. Examples of solutions 1, 2

• Backslash escaping in RegularExpressionValidator

  - by frogbot

  I need to ensure that the input value contains at least one dot, so i use the following: <asp:RegularExpressionValidator runat="server" ControlToValidate="MyInput" Text="*" ErrorMessage="must contain at least one dot" ValidationExpression="\.+" /> And that doesn't work. By inspecting the page source i can see that ASP.NET escapes the backslash character so in java-script it looks like "\\.+". Why does it do so and how do i prevent RegularExpressionValidator from escaping it?

• In CodeIgniter, how to clear "form data" after redirecting page

  - by Obay

  I'm not sure I explained it correctly in the question title, so here's the details: Login controller: function authenticate() { if ( authorized ) { redirect('lobby'); } else { redirect('login'); } } Lobby controller: function index() { //load lobby view } What happens is that in the login page, I enter user / pass, click Login, then authenticate() is called, and redirects me to the Lobby. However, when I click refresh while on the Lobby, the login form gets submitted again, so I get "logged in" again. How do I prevent that from happening?

• How to safely store encryption key in a .NET assembly

  - by Alex

  In order to prevent somebody from grabbing my data easily, I cache data from my service as encrypted files (copy protection, basically). However, in order to do this, I must store the encryption key within the .NET assembly so it is able to encrypt and decrypt these files. Being aware of tools like Red Gate's .NET Reflector which can pull my key right out, I get a feeling that this is not a very safe way of doing it... are there any best practices to doing this?
