• VB.NET - Find a Substring in an ArrayList, StringCollection or List(Of String)

  - by CJM

  I've got some code that creates a list of AD groups that the user is a member of, with the intention of saying 'if user is a member of GroupX then allow admin access, if not allow basic access'. I was using a StringCollection to store this list of Groups, and intended to use the Contains method to test for membership of my admin group, but the problem is that this method only compares the full string - but my AD groups values are formatted as cn=GroupX, etc.... I want to be easily able to determine if a particular substring (i.e. 'GroupX') appears in the list of groups. I could always iterate through the groups check each for a substring representing my AD group name, but I'm more interested in finding out if there is a 'better' way. Clearly there are a number of repositories for the list of Groups, and it appears that Generics (List(Of String)) are more commonly preferred (which I may well implement anyway) but there is no in-built means of checking for a substring using this method either. Any suggestions? Or should I just iterated through the list of groups?

• How to make a remote connection to a MySQL Database Server?

  - by MLB

  Hello: I am trying to connect to a MySQL database server (remote), but I can't. I am using an user with grant privileges (not root user). The error message is the following: Can't obtain database list from the server. Access denied for user 'myuser'@'mypcname' (using password: YES) "myuser" is an user I created with grant access. This user allows me to connect locally to every database. I am using the same software versions in both hosts: MySQL Server 4.1 (server) and EMS SQL Manager 2005 for MySQL, edition 3.7.0.1 (client). The point is that I need to connect to the remote server using a different user, not root user. So, how to make the connection? Thanks.

• Silverlight ClientAccessPolicy issue...I think

  - by Terrence

  Fisrt of all I have my ClientAccessPolicy.xml file in the root of my website. If I access my website using the public domain name like this: h t t p://www.mydomain.com and then go to the page where my SL control is, I get the spinning % numbers up until about 98%, then it quits and my SL control does not appear on the page. If I access my website using the machine name (website is at datacenter, we have vpn setup) like this: h t t p://machinename and then go to the page where my SL control is everything works fine. this must be a ClientAccess Policy issue don't your think? Or what DO you thnik the issue is? Thanks in advance. Here is the contents of my ClientAccessPolicy.xml file: <?xml version="1.0" encoding="utf-8" ?> <access-policy> <cross-domain-access> <policy> <allow-from http-request-headers="*"> <domain uri="*" /> </allow-from> <grant-to> <resource path="/" include-subpaths="true" /> </grant-to> </policy> </cross-domain-access> </access-policy>

• Are there any security issues to avoid when providing a email-or-username-can-act-as-username login

  - by Tchalvak

  I am in the process of moving from a "username/password" system to one that uses email for login. I don't think that there's any horrible problem with allowing either email or username for login, and I remember seeing sites that I consider somewhat respectable doing it as well, but I'd like to be aware of any major security flaws that I may be introducing. More specifically, here is the pertinent function (the query_row function parameterizes the sql). function authenticate($p_user, $p_pass) { $user = (string)$p_user; $pass = (string)$p_pass; $returnValue = false; if ($user != '' && $pass != '') { // Allow login via username or email. $sql = "SELECT account_id, account_identity, uname, player_id FROM accounts join account_players on account_id=_account_id join players on player_id = _player_id WHERE lower(account_identity) = lower(:login) OR lower(uname) = lower(:login) AND phash = crypt(:pass, phash)"; $returnValue = query_row($sql, array(':login'=>$user, ':pass'=>$pass)); } return $returnValue; } Notably, I have added the WHERE lower(account_identity) = lower(:login) OR lower(uname) = lower(:login) ...etc section to allow graceful backwards compatibility for users who won't be used to using their email for the login procedure. I'm not completely sure that that OR is safe, though. Are there some ways that I should tighten the security of the php code above?

• Using Alias in Apache ONLY if local directory not present?

  - by Andrew E.

  Hey all, We're running a reseller web host, and aliasing a particular directory for ALL the sites within. This is all happening through WHM/Cpanel, which could possibly complicate my question. We want all hosts to run their "/concrete" directory through a shared location on the server. This is working fine by adding "Alias /concrete/ "/usr/local/share/concrete5/concrete-latest/concrete/" to the apache include editor in WHM. However, if a local concrete/ directory exists within the particular webroot of the virtual host, we'd rather use that than "/concrete" globally. It would also be nice if we could make this alias change in the context of the virtual host, within WHM (and I haven't found a great way to modify virtual host sections in WHM without hacking a file that I don't believe we're supposed to hack.) Thoughts?

• Better way to kill a Form after the FormClosing event is overridden to hide rather than close?

  - by Paul Sasik

  I have a simple Windows Form that hosts property controls at runtime. To keep the window and its contents alive rather than killing it by handling the FormClosing event, cancel the event and simply hide the form. That's fine but at close of the application I need to actually close the window. I implemented the below but it feels kludgey. Is there a simpler, more clever way to handle this situation? (The form's controller calls KillForm explicitly after it receives a closing event from the main window.) Friend Class HostForm Private _hideInsteadOfClosing As Boolean = True Private Sub HostForm_FormClosing(ByVal sender As Object, ByVal e As FormClosingEventArgs) _ Handles Me.FormClosing If _hideInsteadOfClosing Then Me.Hide() e.Cancel = True End If End Sub Public Sub KillForm() _hideInsteadOfClosing = False Me.Close() End Sub End Class

• How does one implement storage/retrieval of smart-search/mailbox features?

  - by humble_coder

  Hi All, I have a question regarding implementation of smart-search features. For example, consider something like "smart mailboxes" in various email applications. Let's assume you have your data (emails) stored in a database and, depending on the field for which the query will be created, you present different options to the end user. At the moment let's assume the Subject, Verb, Object approach… For instance, say you have the following: SUBJECTs: message, to_address, from_address, subject, date_received VERBs: contains, does_not_contain, is_equal_to, greater_than, less_than OBJECTs: ??????? Now, in case it isn't clear, I want a table structure (although I'm not opposed to an external XMLesque file of some sort) to store (and later retrieve/present) my criteria for smart searches/mailboxes for later use. As an example, using SVO I could easily store then reconstruct a query for "date between two dates" -- simply use "date greater than" AND "date less than". However, what if, in the same smart search, I wanted a "between" OR'ed with another criterion? You can see that it might get out of hand -- not necessarily in the query creation (as that is rather simplistic), but in the option presentation and storage mechanism. Perhaps I need to think more on a more granular level. Perhaps I need to simply allow the user to select AND or OR for each entry independently instead of making it an ALL OR NOTHING type smart search (i.e. instead of MATCH ALL or MATCH ANY, I need to simply allow them to select -- I just don't want it to turn into a Hydra). Any input would be most appreciated. My apologies if the question is a bit incoherent. It is late, and I my brain is toast. Best.

• Keep local MS SQL 2008 DB table and remote SQL Azure DB table in sync

  - by Boomerangertanger

  Hi there, I have a dedicated server which hosts a Windows Service which does a lot of very heavy load stuff and populates a number of SQL Server database tables. However, of all the database tables it populates and works with, I want only one to be synchronised with a remote SQL Azure DB table. This is because this table holds what I called Resolved data, which is the end result of the Windows Service's work. I would like to keep a SQL Azure database table in sync with this database table. As far as I understand, my options are: Move everything onto Azure (but that involves a massive development overhead and risk) Have another Windows Service on the dedicated server which essentially looks at changed records since the last update and then manually update the SQL Azure table

• CURL alternative - Design ideas

  - by Vincent

  All, I am looking for some web application design ideas here. I have a server X that hosts an SDK, which has the capacity to talk a piece of hardware. When I make an HTTPS request from an external PHP web application (hosted on Server Y) to Server X through curl, Server X gives JSON data as a response. I use this data to render my UI for the web app on Server Y. The above method seems to be slow and has a tendency to fail in production if there are too many concurrent requests. Can anybody let me know if there is an alternative to CURL or any other design people are using to pull data like this from servers? Thanks

• Regular expression, excluding .. in suffix of email addy

  - by user1754700

  This is homework, I've been working on it for a while, I've done lots of reading and feel I have gotten pretty familiar with regex for a beginner. I am trying to find a regular expression for validating/invalidating a list of emails. There are two addresses which are giving me problems, I can't get them both to validate the correct way at the same time. I've gone through a dozen different expressions that work for all the other emails on the list but I can't get those two at the same time. First, the addresses. [email protected] - invalid [email protected] - valid The part of my expression which validates the suffix I originally started with @.+\\.[[a-z]0-9]+ And had a second pattern for checking some more invalid addresses and checked the email against both patterns, one checked for validity the other invalidity but my professor said he wanted it all in on expression. @[[\\w]+\\.[\\w]+]+ or @[\\w]+\\.[\\w]+ I've tried it written many, many different ways but I'm pretty sure I was just using different syntax to express these two expressions. I know what I want it to do, I want it to match a character class of "character+"."character+"+ The plus sign being at least one. It works for the invalid class when I only allow the character class to repeat one time(and obviously the ip doesn't get matched), but when I allow the character class to repeat itself it matches the second period even thought it isn't preceded by a character. I don't understand why.

• Looking for a RESTful or SOAP pipeline between WordPress and InterWoven TeamSite

  - by deanpeters

  I've been Googling my brains out trying see if there's a simple way to bridge content to and from WordPress to and from TeamSite. I'm coming at this from the perspective of a WordPress developer. I see in the book "The Definitive Guide to Interwoven TeamSite" (http://bit.ly/d3z4wI) mention of objects for the Interwoven LiveSite product: com.interwoven.livesite.external.impl.RSS com.interwoven.livesite.external.impl.SOAP If I understand the above objects correctly, these allow me to instantiate objects of these data types, which after populating them via various method calls, allow me to render content using com.interwoven.livesite.external.ExternalCall ... but I'm not sure. Nor do I think this approach provides me the 2-way street I seek. As it stands now, from my limited understanding, it appears that the least path of resistance is deploying Interwoven's LiveSite with the existing TeamSite implementation so content can be both consumed and rendered via RSS ... an channel which WordPress can produce and consume; the latter with plugins such as wp-o-matic and/or feedpress. So the question is, does anyone out there have experience with a SOAP or RESTful API approach to InterWoven's TeamSite? If so, can I get some direction on documentation? Or is the addition of LiveSite + RSS the most feasible 2-way channel?

• Sending mail via sendmail from python

  - by Nate

  If I want to send mail not via SMTP, but rather via sendmail, is there a library for python that encapsulates this process? Better yet, is there a good library that abstracts the whole 'sendmail -versus- smtp' choice? I'll be running this script on a bunch of unix hosts, only some of which are listening on localhost:25; a few of these are part of embedded systems and can't be set up to accept SMTP. As part of Good Practice, I'd really like to have the library take care of header injection vulnerabilities itself -- so just dumping a string to popen('/usr/bin/sendmail', 'w') is a little closer to the metal than I'd like. If the answer is 'go write a library,' so be it ;-)

• Ruby On Rails with HTML5 offline apps - Firefox does not cache the application.manifest but Safari does

  - by hoitomt

  I'm working off of this Railscast tutorial: episode 247 I’m up to this point in the tutorial: added the rack-offline gem, added the application.manifest route, and added a reference to the manifest in the html tag. Right before it starts talking about problems with caching. Safari works as intended – When the server is running the page is served. From the server logs I can see that Safari is making a single request to the server every time for the items page. When I turn off the server the page displays as well, even after shutting down the browser and restarting. It appears to be pulling from the application.manifest (cache manifest). Firefox does not work as intended – When accessing the page for the first time, Firefox lets me know that the web page wants to store something locally, I allow. After clicking on allow, Firefox makes 5 requests to the server for the page (from the server log). The hash is different in every request. Is it is possible that the changing hash is triggering Firefox to keep trying to get the new manifest until it reaches some maximum (5 attempts)? Then, after the server is stopped, Firefox will not show the page at all. It looks like it isn’t caching the application.manifest. Firefox also gives you a way to see what sites are storing stuff locally by going to Tools/Options/Advanced/Network (Firefox/Preferences/Advanced/Network on Apple). I see localhost there but the size is 0 bytes. So for some reason, Firefox is not downloading my application.manifest along with the files

• make mongrel_rails (localhost:3000) visible to a virtual machine

  - by Max Williams

  I develop rails in ubuntu and i just set up a virtualbox windows xp virtual machine for IE testing. I'd like to be able to run mongrel_rails in ubuntu and then jump into the vm to check it out, so i can jump back, make a change, jump into the vm again, reload the page and test it, etc. Is this possible? In this sort of situation in the past i've had to set up an apache server on my dev machine and run mongrel under that, in order to get an externally visible (ie visible to my local network) ip address that i then paste into the address bar of IE in the vm. Is this really necessary? Is there a simpler way? Can i do something with my /etc/hosts or sites-available files to just make up some arbitrary network address which points to localhost:3000 in ubuntu? Or something? thanks, max

• Stopping cookies being set from a domain (aka "cookieless domain") to increase site performance

  - by Django Reinhardt

  I was reading in Google's documentation about improving site speed. One of their recommendations is serving static content (images, css, js, etc.) from a "cookieless domain": Static content, such as images, JS and CSS files, don't need to be accompanied by cookies, as there is no user interaction with these resources. You can decrease request latency by serving static resources from a domain that doesn't serve cookies. Google then says that the best way to do this is to buy a new domain and set it to point to your current one: To reserve a cookieless domain for serving static content, register a new domain name and configure your DNS database with a CNAME record that points the new domain to your existing domain A record. Configure your web server to serve static resources from the new domain, and do not allow any cookies to be set anywhere on this domain. In your web pages, reference the domain name in the URLs for the static resources. This is pretty straight forward stuff, except for the bit where it says to "configure your web server to serve static resources from the new domain, and do not allow any cookies to be set anywhere on this domain". From what I've read, there's no setting in IIS that allows you to say "serve static resources", so how do I prevent ASP.NET from setting cookies on this new domain? At present, even if I'm just requesting a .jpg from the new domain, it sets a cookie on my browser, even though our application's cookies are set to our old domain. For example, ASP.NET sets an ".ASPXANONYMOUS" cookie that (as far as I'm aware) we're not telling it to do. Apologies if this is a real newb question, I'm new at this! Thanks.

• Oracle Forms on-button-pressed trigger to solve three scenarios

  - by DBase486

  Hello, I'm writing a when-button-pressed trigger on a save button for an Oracle Forms 6i form, and it has to fulfill a couple of scenarios. Here's some background information: the fields we're primarily concerned with are: n_number, alert_id, end_date For all three scenarios we are comparing candidate records against the following records in the database (for the sake of argument, let's assume they're the only records in the database so far): alert_id|| n_number|| end_date ------------------------------------- 1|| 5|| _______ 2|| 6|| 10/25/2009 Scenario 1: The user enters a new record: alert_id 1 n_number 5 end_date NULL Objective: prevent the user from committing duplicate rows Scenario 2: The user enters a new record: alert_id 1 n_number 10 end_date NULL Objective: Notify the user that this alert_id already exists, but allow the user the ability to commit the row, if desired. Scenario 3: The user enters a new record: alert_id 2 n_number 6 end_date NULL Objective: Notify the user that this alert_id has occurred in the past (i.e. it has a not-null end_date), but allow the user to commit the row, if desired. I've written the code, which seems to comply with the first two scenarios, but prevents me from fulfilling the third. Issues: When I enter the third scenario case, I am prompted to commit the record, but when I attempt this, the "duplicate_stop" alert pops up, preventing me. Issues: I'm getting the following error: ORA-01843: not a valid month. While testing the code for the third scenario in Toad (hard-coding the values, etc) things seemed to be fine. Why would I encounter these problems at run-time? Help is very much appreciated. Thank you

• Session troubles when used on BT hosting

  - by YsoL8

  Hello I have developed a site for a client with a pre-existing BT hosting package. Since going live there has been a problem where $_session loses it's data between pages. I have previously fixed the problem, but somehow it has become unfixed. Last time this problem happened, my research indicated that there is something funny with BT's setup when using sessions, and that article provided this code: if(ini_get('register_globals') == 1) if(is_array($_SESSION)) foreach(array_keys($_SESSION) as $var_to_kill) unset($$var_to_kill); Which even though it looks broken to me, did in fact reduce the problem to a very low level. (i.e one drop out a day). However, today my client is in touch again and surprise surprise, the problem is back. Does anyone know of a solution? (My client has already stated they will not change hosts!) Oliver

• Licensing for the undecided

  - by Jasper

  I am creating a game in C++. Now I am not sure on how I will distribute it yet - though I am pretty sure that I won't be asking money for it. And I am looking into a licensing and I wondered if there is a license that is suited for the undecided like me. My current releases (which are really really early versions of the game, with far from full functionality) are executable only. However, I am actually thinking that I might release the source on an open source license. For now, I am the only contributor, so that would be no problem as I only need my own permission to move to a less restrictive license. However, when I allow other people to contribute, I would need all their permissions to do so (right?). So I was wondering if there is a license that let's me distribute the game executable only for now, but will let me switch to a less restrictive license if I want. Basically I need a license in which contributors give permission to switch to a less restrictive license up front. Does anybody know of license (or other construction) that would allow me to do so?

• Windows authetication with Silverlight custom binding.

  - by sfx

  Hello, I am trying to set up security within a web.config file for a WCF service hosted in IIS but keep getting the error message: Security settings for this service require 'Anonymous' Authentication but it is not enabled for the IIS application that hosts this service. I have read Nicholas Allen’s blog (link text) and it appears that this is the route that I need to take. However, I am using “binaryMessageEncoding” in a customBinding for my Silverlight service, and as such, I’m not sure how to apply this type of security to such an element. This is how my custom binding looks in config at present: <customBinding> <binding name="silverlightBinaryBinding"> <binaryMessageEncoding /> <httpTransport /> </binding> </customBinding> Has anyone had any experience getting Windows authentication to work with a custom binding using binaryMessageEncoding? Cheers, sfx

• SIMPLE PHP MVC Framework [closed]

  - by Allen

  I need a simple and basic MVC example to get me started. I don't want to use any of the available packaged frameworks. I am in need of a simple example of a simple PHP MVC framework that would allow, at most, the basic creation of a simple multi-page site. I am asking for a simple example because I learn best from simple real world examples. Big popular frameworks (such as code igniter) are to much for me to even try to understand and any other "simple" example I have found are not well explained or seem a little sketchy in general. I should add that most examples of simple MVC frameworks I see use mod_rewrite (for URL routing) or some other Apache-only method. I run PHP on IIS. I need to be able to understand a basic MVC framework, so that I could develop my own that would allow me to easily extend functionality with classes. I am at the point where I understand basic design patterns and MVC pretty well. I understand them in theory, but when it comes down to actually building a real world, simple, well designed MVC framework in PHP, I'm stuck. Edit: I just want to note that I am looking for a simple example that an experienced programmer could whip up in under an hour. I mean simple as in bare bones simple. I don't want to use any huge frameworks, I am trying to roll my own. I need a decent SIMPLE example to get me going.

• Session being reset when using sub-domain.

  - by Adam Witko

  Hi, I'm trying to use sub-domains in my ASP.NET website but I'm coming across a few problems with the session being reset. I've edited my hosts file to have 'localhost', 'one.localhost' and 'two.localhost'. I can go to any of these URLs and do what I need to do and login to my system. The session mode is defined as follows in the web.config: I'm using SQLServer as the website will be ran as a webfarm. What I'm finding is when I click something that causes a postback all the session is lost and a new session id is created, when this occurs my website is now 'localhost' rather than the logged in 'one.localhost' for example. Does anyone know what might be causing this? Cheers

• Apples, oranges, and pointers to the most derived c++ class

  - by Matthew Lowe

  Suppose I have a bunch of fruit: class Fruit { ... }; class Apple : public Fruit { ... }; class Orange: public Fruit { ... }; And some polymorphic functions that operate on said fruit: void Eat(Fruit* f, Pesticide* p) { } void Eat(Apple* f, Pesticide* p) { ingest(f,p); } void Eat(Orange* f, Pesticide* p) { peel(f,p); ingest(f,p); } OK, wait. Stop right there. Note at this point that any sane person would make Eat() a virtual member function of the Fruit classes. But that's not an option, because I am not a sane person. Also, I don't want that Pesticide* in the header file for my fruit class. Sadly, what I want to be able to do next is exactly what member functions and dynamic binding allow: typedef list<Fruit*> Fruits; Fruits fs; ... for(Fruits::iterator i=fs.begin(), e=fs.end(); i!=e; ++i) Eat(*i); And obviously, the problem here is that the pointer we pass to Eat() will be a Fruit*, not an Apple* or an Orange*, therefore nothing will get eaten and we will all be very hungry. So what I really want to be able to do instead of this: Eat(*i); is this: Eat(MAGIC_CAST_TO_MOST_DERIVED_CLASS(*i)); But to my limited knowledge, such magic does not exist, except possibly in the form of a big nasty if-statement full of calls to dynamic_cast. So is there some run-time magic of which I am not aware? Or should I implement and maintain a big nasty if-statement full of dynamic_casts? Or should I suck it up, quit thinking about how I would implement this in Ruby, and allow a little Pesticide to make its way into my fruit header?
