• List<T> add method in C#

  - by Nano HE

  Hello. As I know. List Add method works as below. List<string> cities = new List<string>(); cities.Add("New York"); cities.Add("Mumbai"); cities.Add("Berlin"); cities.Add("Istanbul"); If I designed the data structure as this List<object> lstObj = new List<object>(); if (true) // string members { cities.Add("New York"); cities.Add("Istanbul"); } else // List obj members here { List<object> AListObject= new List<object>(); cities.Add(AListObject); // how to handle this? } Does the List Add method works or not if I add different types members in the same function.

• PHP question about global variables and form requests

  - by user220201

  Hi, This is probably a stupid question but will ask anyway sine I have no idea. I have written basic php code which serve forms. Say I have a login page and I serve it using the login.php page and it will be called in the login.html page like this - <form action="login.php" method="post"> By this it is also implied that every POST needs its own php file, doesn't it? This kind of feels weird. Is there a way to have a single file, say code.php, and just have each of the forms as functions instead? EDIT: Specifically, say I have 5 forms that are used one after the other in my application. Say after login the user does A, B, C and D tasks each of which are sent to the server as a POST request. So instead of having A.php, B.php, C.php and D.php I would like to have a single code.php and have A(), B(), C() and D() as functions. Is there a way to do this? Also on the same note, how do I deal with say a global array (e.g. an array of currently logged in users) across multiple forms? I want to do this without writing to a DB. I know its probably better to write to a DB and query but is it even possible to do it with a global array? The reason I was thinking about having all the form functions in one file is to use a global array. Thanks, - Pav

• Jquery: Is there some way to make val() return an empty string instead of 'undefined' for an empty list?

  - by Chris

  With Jquery, is there some way to make val() return an empty string instead of 'undefined' when called against an empty list of elements? E.g., I have this code: var x = $('#my-textbox-id').not('.watermark').val(); The idea is that I want to get the value of my textbox, but I want an empty string if it is currently showing the watermark (i don't want the watermark value!). The selector works, but i don't want 'undefined' - I want an empty string ''.

• Checking OpenGL resource leaks

  - by kamziro

  So I have a rather large openGL program going, and checking for normal memory leaks (those by new and delete) is rather trivial -- just run it on valgrind. But what is the best way to check for potential opengl leaks? Is there an opengl utility that'll tell you how many resources (e.g framebuffers) are being used at the time, or such? Or is the only way to attach a counter to every glGenBlah and glDeleteBlah pairs?

• UIView Subview Does not autoresize on orientation change

  - by Jason

  In my iPhone app, I have a view controller with two views (essentially, a front & back view). The front view is the main UIView, and the back view is a secondary UIView which is added as a subview using [self.view addSubview:backView] when showing the back and [backView removeFromSuperview] when hiding it. However, when the orientation changes, I have the following issue: the main UIView (frontView) rotates & all of its elements resize properly, but the secondary/subview UIView (backView) does not rotate & all of its elements do not resize properly. Does anyone have suggestions on how to make the secondary UIView autoresize properly according to the rules I have set in Interface Builder?

• Best .Net/C# book for an interview

  - by DrunkenBeard

  Hi, I'm having an interview for an internship in the coming days and would like to know if there are any books that are particulary suited for preparing interviews. The interview is not particulary hard, just some questions about .Net and C# plus an algorithm to code. I tried C# in a Nutshell but it goes in too much detail for what I want to achieve. I'm more looking for a good yet small book that explains the important concepts of the .Net framework and C#, I already know the details, just want formal explanations so I'm confident when answering. Thanks :)

  - by Adam Storr

  Hello! I am trying to make one of my tab buttons go to the root using popToRootViewControllerAnimated. My question is: where do I put this code for it to work? I have my tabs created through Interface Builder... do they have to be hard coded for this to work?

• Active Directory theme policies

  - by Tuinslak

  Hey, I'm currently managing a terminal server in a domain. As the TS-service just got installed, previous users (I logged in with every user once to test it and set up a few things) use the default windows 2008 theme. New users automatically use the fancy Aero theme. Is there a way to push the Aero theme to all current users? I currently have something like this in my policies: However, when logging in with a user, the theme is not changed. Only if I disable "prohibit access to the control panel", the theme can be changed (doesn't seem to change automatically). But this gives them access to every other control panel feature as well. And giving users only access to "desk.cpl" CP-applet, gives them an access error as well when attempting to change the theme. Another question: can I, as admin, take over and/or log in as another user when that user is not logged in? Thanks

• How to utilize Varnish for A/B Testing and Feature Rollout?

  - by Ken

  Hi all, wasn't really sure if this should go here on or stackoverlow - admins, please move if i'm mistaken (and sorry). Today we have our web layer exposed to the world. We would like to add Varnish in front of our web layer to accelerate the site and reduce calls to the backend. However, we have some concerns and i was wondering how most people approach them: A/B Testing - How do you test two "versions" of each page and compare? I mean, how does varnish know which page to serve up? If and how do you save seperate versions on each page? Feature rollout - how would you set up a simple feature rollout mechanism? Let's say i want to open a new feature/page to just 10% of the traffic.. and then later increase that to 20%? How do you handle code deployments? Do you purge your entire varnish cache every deployment? (We have deployments on a daily basis). Or do you just let it slowly expire (using TTL)? Any ideas and examples regarding these issues is greatly appreciated! Thanks in advance. Ken.

• psloggedon timeout question.

  - by user60707

  Hi guys, I have a list of machine names from my network that I have put in a batchfile to run through the list and show me who is logged onto each. psloggedon \machineA psloggedon \machineB psloggedon \machineC psloggedon \machineD psloggedon \machineE psloggedon \machineF Psloggedon works fine, however when it hits a machine that isnt actually on the network, it hangs for a good 30 - 60 seconds before moving onto the next machine...I was just wondering if there was any way to speed this up so that if it hits a machine that isnt on the network, it moves onto the next machine in the list much quicker. I have read in other places that this could be possible by adding a ping -n loop into the command but im not sure how to get that to work? any ideas guys? Many thanks in advance. Jimmy

• Log "date -s" command

  - by LinuxPenseur

  Hi, I know that the date -s <STRING> command sets the time described by the string STRING. What i want is to log the above command whenever it is used to set the time into the file /tmp/log/user.log. In my Linux distribution the logging is done by syslog-ng. I already have some logs going into /tmp/log/user.log. This is the content of /etc/syslog-ng/syslog-ng.conf in my system for logging into /tmp/log/user.log destination d_notice { file("/tmp/log/user.log");}; filter f_filter10 { level(notice) and not facility(mail,authpriv,cron); }; log { source(s_sys); filter(f_filter10); destination(d_notice); }; What should i do so that date -s command is also logged into /tmp/log/user.log

• Installing/enabling PHP Pecl Intl extension on CentOs 5

  - by Marijn Huizendveld

  Original question: I'm having trouble installing the PHP Pecl Intl extension on my CentOs 5 machine. After installing both icu and libicu with the following commands: $ yum install icu $ yum install libicu I tried to install the Intl extension like so: $ /usr/bin/pecl install intl I selected to search for the default location for the ICU libraries and header files. It ends up crashing like this: checking whether to enable internationalization support... yes, shared checking for icu-config... no checking for location of ICU headers and libraries... not found configure: error: Unable to detect ICU prefix or no failed. Please verify ICU install prefix and make sure icu-config works. ERROR: `/tmp/pear/temp/intl/configure --with-icu-dir=DEFAULT' failed update After successfully installing the development version of icu as suggested by RusAlex (thanks RusAlex) like so: $ yum install libicu-devel I ran into a new problem which I also encountered locally the following command: $ /usr/bin/pecl install intl now produces this error: /private/tmp/pear/temp/intl/collator/collator_class.c:92: error: duplicate 'static' /private/tmp/pear/temp/intl/collator/collator_class.c:96: error: duplicate 'static' /private/tmp/pear/temp/intl/collator/collator_class.c:101: error: duplicate 'static' /private/tmp/pear/temp/intl/collator/collator_class.c:107: error: duplicate 'static' make: *** [collator/collator_class.lo] Error 1 ERROR: `make' failed It appears to have something to do with PHP 5.3 being bundled with Intl already. But how can I enable this extension, if I look in my PHP Info than I cannot find any reference to it...

• I need some MySQL lookup table advice

  - by Gary Beam

  I have a MySQL database with about 200 tables. 50 of these are small 2-field 'id-data' lookup tables. Several of these DB's are hosted on a shared server. I have been informed that I need to reduce the total number of tables in the shared hosting environment because of performance issues relating to too many tables. My question is: Could/Should the 50 2-Field lookup tables be combined into a single 3-field table with 'id-field_name-data' Fields? Even if this can be done, I will have a lot of work to do on the PHP user application. My other choice is moving the DB's to a dedicated server at much higher hosting cost. I don't believe my 200 table DB's are actually causing any performance issues on this shared hosting server, at least not from the user application standpoint. There are never more than 10 of these tables joined in any single query; although I have seen some very-slow queries generated by phpmyadmin on these DB's.

• How do I resolve "conflicting accounts" in google apps without breaking links to online photos on picasa?

  - by lee

  I have been using google apps for some time, and only recently learned I have what google calls "conflicting accounts" which is creating a problem I haven't been able to resolve. Turns out that the apps account really only covers email, google docs, and the calendar and not other features like picasa, blogger, youtube etc. and at some point they gave me a non-apps google account with my same (proprietary non-gmail) email address for the additional apps. This is the "conflicting account." I had noticed that I sometimes had to come in through another door when I went back and forth, between docs, picasa, and mail let's say, but never understood why since it was the same username and password and I didn't get any communication about it at the time. Google is now in the process of giving google apps users access to the additional apps and providing instructions for consolidating the two accounts. But if I want to move my picasa site into the new apps structure I have to download my albums and re-synch them. This would be disastrous for me as I have hundreds of photos embedded in my websites, and new web addresses would break all the connections. The alternative seems to be to rename my "personal" (non-apps) accounts as described at http://www.google.com/support/a/bin/answer.py?answer=185186: Users with conflicting Google Accounts can easily resolve their conflicts by renaming their personal Google Accounts, and the data in their personal accounts will remain safe and accessible to them. Here’s how a user can rename their personal Google Account: * Step 1: Visit www.google.com/accounts and sign in with your personal Google Account * Step 2: Click ‘Change email’ under ‘Personal Settings’ * Step 3: Enter a different email address where you can receive mail, enter your password, and click ‘Save email address’ * Step 4: Check your other email If your users don’t have different email addresses where they can receive mail, they can resolve the conflict by renaming their personal Google Accounts to @gmail.com addresses instead. Sounds easy enough, right? I gave them a gmail address. The wizard said "sorry you can't use a gmail account for this" --which contradicts the last paragraph above but ok, I switched to a new email address I just created for one of my domains. I can send email back and forth between this account and my google apps account with no problem. But when I try to use it as a replacement on the "personal" side I always get "The password you gave is incorrect." I have tried it over and over and know the password is correct. Since I like to get all my emails though one web interface I initially had the new email set up as an add-on to my google apps email account, but noting that the instructions said the "personal account" email could not be associated with any other gmail account I took it off and went back to accessing it via horde so there would be no conflict there, which seemed to make no difference. I can't figure out why it won't accept the password. Does anyone have any thoughts about that? or suggestions for another way to resolve my picasa problem? any help at all is greatly appreciated. Lee
