  • TSQL Email Validation (without regex)

    - by Eric Z Beard
    Ok, there are a million regexes out there for validating an email address, but how about some basic email validation that can be integrated into a TSQL query for Sql Server 2005? I don't want to use a CLR procedure or function. Just straight TSQL. Has anybody tackled this already?

    - by cmaduro
    Does the Elliptic curve diffie hellman calculation look any different from the standard one defined here: /* * The basic Diffie-Hellman Key Agreement Equation * * The client initiates * A = g^a mod p * * Sends (g p A) to the server * * The server calculates B * B = g^b mod p * * Sends B back to client * * The client calculates K * K = B^a mod p * * The server calucaltes K * K = A^b mod p * */ Or is it just a specific way of selecting g, a, p and b?

  • Do you have any tips for commenting code?

    - by Rob Wells
    G'day, I've read both of Steve McConnell's excellent Code Complete books "Code Complete" and "Code Complete 2" and was wondering if people have any other suggestions for commenting code.co My commenting mantra could be summed up by the basic idea of expressing "what the code below cannot say". While enjoying this interesting blog post by Jeff about commenting I was still left wondering "When coding, when do you feel a comment is required?"

  • Can the Microsoft Paint Edit Colors Dialog be supplemented?

    - by Gus
    I have written a WinForms application that presents a color picker, limited to the known colors. My environment is Visual Studio C# Express 2008, C#, and Framework 2.0. Currently the MS Paint Colors menu item only presents an Edit Colors dialog. I would like to supplement that by causing the Colors menu item to display both "Edit Colors" and "Edit Known Colors". Can I accomplish this? If so, please provide a citation (or code if preferrred).

  • How to implement Template Inheritance (like Django?) in PHP5

    - by anonymous coward
    Is there an existing good example, or how should one approach creating a basic Template system (thinking MVC) that supports "Template Inheritance" in PHP5? For an example of what I define as Template Inheritance, refer to the Django (a Python framework for web development) Templates documentation: http://docs.djangoproject.com/en/dev/topics/templates/#id1 I especially like the idea of PHP itself being the "template language", though it's not necessarily a requirement. If listing existing solutions that implement "Template Inheritance", please try to form answers as individual systems, for the benefit of 'popular vote'.

    - by coubeatczech
    Hi, I have browsed lift's MegaProtoUser and encountered this construction: ??("Last Name"). Can anyone explain, what that means? Also, I didn't find a way how to add a custom field into MegaProtoUser. The maven's lift's basic archetype defines another field, but it never shows anywhere. (Version 1.0) Thanks for answering

  • Apache tiles and body onload event. Known issue?

    - by Angus
    We're prototyping a new visual framework using Apache Tiles for markup templating. Often the document onload event (actually prototype's dom:loaded event) is getting fired before all DOM objects are actually loaded Is it possible that the tiles templates are loading in an asynchronous fashion and therefore doing an end run around the event handler? Has anyone else had this experience? Can anyone share a robust workaround? thanks in advance

  • Good Administration Center Templates

    - by Alec Smart
    Hello, This may not be a programming question per se. But I am wondering what template do you use for your sites/webapps admin centers. Am looking primarily at free templates that give a basic structure. I know I can build my own, but I haven't had too much success in something that works for all my webapps/sites. Wondering if there is something nice and comprehensive available. Thank you for your time.

  • Most effective way to draw 4 lines on a screen?

    - by Ross
    basic question, but I'm unsure: I want to draw 4 short lines 1px lines on a view. What is the best way to approach this task? Options:- Load an image of the line, can create 4 UIImageViews with it. Create my own subclass of a UIView that draws a line in the draw rect method. Draw elsewhere on another view, another UIImageView that has an UIImage inside it (is this possible?) Another way? Thanks Ross

  • Tomcat 403 error after LDAP authentication.

    - by user352636
    I'm currently trying to use an LDAP server to authenticate users who are trying to access our Tomcat setup. I believe I have managed to get the LDAP authentication working in the form of a JNDI realm call from Tomcat, but immediately after the user enters their password Tomcat starts throwing 403 (permission denied) errors for everything except from the root page (ttp://localhost:1337/). I have no idea why this is happening. I am following the example at http://blog.mc-thias.org/?title=tomcat_ldap_authentication&more=1&c=1&tb=1&pb=1 . server.xml (the interesting/changed bits) <Realm className="org.apache.catalina.realm.JNDIRealm" debug="99" connectionURL="ldap://localhost:389" userPattern="uid={0},ou=People,o=test,dc=company,dc=uk" userSubTree="true" roleBase="ou=Roles,o=test,dc=company,dc=uk" roleName="cn" roleSearch="memberUid={1}" /> <Valve className="org.apache.catalina.authenticator.SingleSignOn" /> web.xml (the interesting/changed bits) <security-constraint> <display-name>Security Constraint</display-name> <web-resource-collection> <web-resource-name>Protected Area</web-resource-name> <!-- Define the context-relative URL(s) to be protected --> <url-pattern>/*</url-pattern> <!-- If you list http methods, only those methods are protected --> </web-resource-collection> <auth-constraint> <!-- Anyone with one of the listed roles may access this area --> <role-name>admin</role-name> <role-name>regular</role-name> </auth-constraint> </security-constraint> <!-- Default login configuration uses form-based authentication --> <login-config> <auth-method>BASIC</auth-method> </login-config> <!-- Security roles referenced by this web application --> <security-role> <role-name>admin</role-name> <role-name>regular</role-name> </security-role> I cannot access my LDAP setup at the moment, but I believe it is alright as the login is accepted by the BASIC auth method, it's just tomcat that is rejecting it. The roles should be as defined in web.xml - admin and regular. If there is any other information you require me to provide, please just ask! My thanks in advance to anyone who can help, and my apologies for any major mistakes I have made - yesterday was pretty much the first time I'd ever heard of LDAP =D. EDIT: Fixed the second xml segment. Apologies for the formating-fail.

  • Reference XSLT-file using a project relative way (instead of an absolute path)

    - by Binary255
    The file at xsltFileName is in my project WebSite2 (at the root-level of the project). I currently use an absolute path to get the XSLT file name: XslCompiledTransform xslt = new XslCompiledTransform(); String xsltFileName = "file:///C:\\Documents and Settings\\kentl\\My Documents\\Visual Studio 2005\\WebSites\\WebSite2\\page.xsl"; xslt.Load(xsltFileName); I would like to have a solution without an absolute path. What would be the cleanest way?

  • What eletronic scrum/kanban board do you use and recommend for distributed teams?

    - by Derick Bailey
    I have a coworker on a team that is fairly distributed, fairly large (for our company) and wants to take advantage of visual management tools like scrum / kanban boards. Since they are a somewhat distributed team, though, all of the issue management / work management must be done via an electronic tool (we currently use Trac). What issue / work management tools, with a visualization of a scrum / kanban board, do you use for your distributed scrum / kanban teams? would you recommend it, and if so, why? Thanks.
