  • iframe reaches bottom of page

    - by John
    Is there a way to make the height of the <iframe> reach exactly the bottom of the page? It is hard to judge by using height:xx%, and it might be dependent on browser. The code is below: <!DOCTYPE html> <html> <body style="margin:0"> <p style="margin:10px"> hello </p> <iframe src="http://www.weather.com" style="width:100%; height:95%"></iframe> </body> </html>

  • What's the proper size of Default png's for iPad?

    - by David John
    I am confused by conflicting information. Most commonly I see these being the sizes quoted for the various Default images: Launch image Portrait Default-Portrait.png 768 x 1004 Launch image Portrait [email protected] 1536 x 2008 Launch image Landscape [email protected] 2048 x 1496 Launch image Landscape Default-Landscape.png 1024 x 748 Seemed like slightly unusual sizes, but I went along with it and dragged the images into the Launch images section in XCode. XCode however promptly puts little yellow triangles over these images and tell me that the sizes should be: 768x1024, 1536x2048, 1024x768 and 2048x1536 Oh and one last important bit. Do I really need to have all these images for submission to the app store? It's really not clear which images are required and which are just recommended. Mine is a Universal app btw if that makes any difference.

  • Using traversal by pointer to check whether a string is repeated

    - by Bob John
    bool repeat_char(char *s, int n); //R: s is a C-string of at least n non-NUL characters and n > 0 //E: returns true if the first n characters are fully repeated throughout the string s, false // otherwise. I'm having trouble implementing this function using traversal by pointer. I was thinking that I could extract the first n characters from s, then use that in a comparison with s, but I'm not sure how I could do that. If I'm traversing through s one character at a time, how can I check that it matches a block of text, such as the first n characters of s? Thanks!

  • Why am I getting a MySQL error?

    - by John Hoffman
    Here is my query. Its intention is allow access to properties of the animals that constitute a match of two animals. The match table contains columns for animal1ID and animal2ID to store which animals constitute the match. SELECT id, (SELECT * FROM animals WHERE animals.id=matches.animal1ID) AS animal1, (SELECT * FROM users WHERE animals.id=matches.animalID) AS animal2 FROM matches WHERE id=5 However, MySQl returns this error: Operand should contain 1 column(s). Why? Is there an alternative way to do this, perhaps with a JOIN statement?

  • Convert list of dicts to string

    - by John
    I'm very new to Python, so forgive me if this is easier than it seems to me. I'm being presented with a list of dicts as follows: [{'directMember': 'true', 'memberType': 'User', 'memberId': '[email protected]'}, {'directMember': 'true', 'memberType': 'User', 'memberId': '[email protected]'}, {'directMember': 'true', 'memberType': 'User', 'memberId': '[email protected]'}] I would like to generate a simple string of memberIds, such as [email protected], [email protected], [email protected] but every method of converting a list to a string that I have tried fails because dicts are involved. Any advice?

  • switch vs. if...else if...else

    - by John Hartsock
    Guys I have a couple of questions: Is there a preformance difference in Javascript between a switch statement and an if...else if....else? If so why? Is the behavior of switch and if...else if...else different across browsers? (FireFox, IE, Chrome, Opera, Safari) The reason for asking this question is it seems that I get better preformance on a switch statement with approx 100 cases in Firefox. But in IE it get better preformance with 100 if...else if...else.

    I need to write callback function on clicking an anchor with target="_blank". <a rel="external" href="http://twitter.com/" target="_blank"> <img src="twitter.png"> </a> I think, following code block will do it. $("a[target='_blank']").click(function() { // action required }); Is there any other way where we can get an event with new tab opens? For example: The unload event is sent to the window element when the user navigates away from the page. If I think same perspective, Is there any event sent to window when a new tab opens.

  • PHP DateTime accept multiple formats?

    - by John Smith
    I'm trying to construct a DateTime object with multiple accepted formats. According to the DateTime::createFromFormat docs, the first parameter (format) must be a string. I was wondering if there was a way to createFromFormats. In my case, I want the year for my format to be optional: DateTime::createFromFormat('Y-m-d', $date); DateTime::createFromFormat('m-d', $date); so that a user can input just 'm-d' and the year would be assumed 2013. If I wanted multiple accepted formats, would I have to call createFromFormat each time? Shortest thing for my scenario is: DateTime::createFromFormat('m-d', $date) ?: DateTime::createFromFormat('Y-m-d', $date);

  • Nesting if else statements in PHP to validate a URL

    - by John
    I'm currently writing up a function in order to validate a URL by exploding it into different parts and matching those parts with strings I've defined. This is the function I'm using so far: function validTnet($tnet_url) { $tnet_2 = "defined2"; $tnet_3 = "defined3"; $tnet_5 = "defined5"; $tnet_7 = ""; if($exp_url[2] == $tnet_2) { #show true, proceed to next validation if($exp_url[3] == $tnet_3) { #true, and next if($exp_url[5] == $tnet_5) { #true, and last if($exp_url[7] == $tnet_7) { #true, valid } } } } else { echo "failed on tnet_2"; } } For some reason I'm unable to think of the way to code (or search for the proper term) of how to break out of the if statements that are nested. What I would like to do check each part of the URL, starting with $tnet_2, and if it fails one of the checks ($tnet_2, $tnet_3, $tnet_5 or $tnet_7), output that it fails, and break out of the if statement. Is there an easy way to accomplish this using some of the code I have already?

  • SQL SERVER – TechEd India 2012 – Content, Speakers and a Lots of Fun

    - by pinaldave
    TechEd is one event which every developers and IT professionals are looking forward to attend. It is opportunity of life time and no matter how many time one gets chance to engage with it, it is never enough. I still remember every single moment of every TechEd I have attended so far. We are less than 100 hours away from TechEd India 2012 event.This event is the one must attend event for every Technology Enthusiast. Fourth time in the row I am going to attend this event and I am equally excited as the first time of the event. There are going to be two very solid SQL Server track this time and I will be attending end of the end both the tracks. Here is my view on each of the 10 sessions. Each session is carefully crafted and leading exeprts from industry will present it. Day 1, March 21, 2012 T-SQL Rediscovered with SQL Server 2012 – This session is going to bring some of the lesser known enhancements that were brought with SQL Server 2012. When I learned that Jacob Sebastian is going to do this session my reaction to this is DEMO, DEMO and DEMO! Jacob spends hours and hours of his time preparing his session and this will be one of those session that I am confident will be delivered over and over through out the next many events. Catapult your data with SQL Server 2012 Integration Services – Praveen is expert story teller and one of the wizard when it is about SQL Server and business intelligence. He is surely going to mesmerize you with some interesting insights on SSIS performance too. Processing Big Data with SQL Server 2012 and Hadoop – There are three sessions on Big Data at TechEd India 2012. Stephen is going to deliver one of the session. Watching Stephen present is always joy and quite entertaining. He shares knowledge with his typical humor which captures ones attention. I wrote about what is BIG DATA in a blog post. SQL Server Misconceptions and Resolutions – I will be presenting this Session along with Vinod Kumar. READ MORE HERE. Securing with ContainedDB in SQL Server 2012 – Pranab is expert when it is about SQL Server and Security. I have seen him presenting and he is indeed very pleasant to watch. A dry subject like security, he makes it much lively. A Contained Database is a database which contains all the necessary settings and metadata, making database easily portable to another server. This database will contain all the necessary details and will not have to depend on any server where it is installed for anything. You can take this database and move it to another server without having any worries. Day 3, March 23, 2012 Peeling SQL Server like an Onion: Internals Demystified – Vinod Kumar has been writing about this extensively on his other blog post. In recent conversation he suggested that he will be creating very exclusive content for this presentation. I know Vinod for long time and have worked with him along many community activities. I am going to pay special attention to the details. I know Vinod has few give-away planned now for attending the session now only if he shares with us. Speed Up – Parallel Processes and unparalleled Performance – Performance tuning is my favorite subject. I will be discussing effect of parallelism on performance in this session. Here me out, there will be lots of quiz questions during this session and if you get the answers correct – you can win some really cool goodies – I Promise! READ MORE HERE. Keep your database available – AlwaysOn – Balmukund is like an army man. He is always ready to show and prove that he has coolest toys in terms of SQL Server and he knows how to keep them running AlwaysON. Availability groups, Listener, Clustering, Failover, Read-Only replica etc all will be demo’ed in this session. This is really heavy but very interesting content not to be missed. Lesser known facts about SQL Server Backup and Restore – Amit Banerjee – this name is known internationally for solving SQL Server problems in 140 characters. He has already blogged about this and this topic is going to be interesting. A successful restore strategy for applications is as good as their last good known backup. I have few difficult questions to ask to Amit and I am very sure that his unique style will entertain people. By the way, his one of the slide may give few in audience a funny heart attack. Top 5 reasons why you want SQL Server 2012 BI – Praveen plans to take a tour of some of the BI enhancements introduced in the new version. Business Insights with SQL Server is a critical building block and this version of SQL Server is no exception. For the matter of the fact, when I saw the demos he was going to show during this session, I felt like that I wish I can set up all of this on my machine. If you miss this session – you will miss one of the most informative session of the day. Also TechEd India 2012 has a Live streaming of some content and this can be watched here. The TechEd Team is planning to have some really good exclusive content in this channel as well. If you spot me, just do not hesitate to come by me and introduce yourself, I want to remember you!

    - by Dave Campbell
    It's always a double-edged sword when I get to this point in a give-away... I want to give everyone something, but a deal is a deal :) It's also only through the benevolence of the folks at Manning Press that I can even do this, so thank you! The Winners Getting right to it, the winners are: Jaganadh G Stephen Owens Jan Hannemann Notice there are 3 names, not 2... I was told late last week to pick a 3rd name, so thanks again Manning! I've already received email from my contact, and they've been waiting for me to send them the email. You should be hearing from them shortly I think. For everyone else, keep your eyes on my blog... as I told Manning, I like giving away other people's stuff :) Have a great day, and if you're anywhere near Phoenix and interested in Silverlight, I'll see you tomorrow at the Scott Gu Event, and Stay in the 'Light!

  • PPL and TPL sessions on channel9

    - by Daniel Moth
    Back in June there was an internal conference in Redmond ("Engineering Forum") aimed at Microsoft engineers, and delivered by Microsoft engineers. I was asked to put together a track on Multi-Core development, so I picked 6 parallelism experts and we created 6 awesome sessions (we won the top spot in the Top 10 :-)). Two of the speakers kept the content fairly external-friendly, so we received permission to publish their recordings publicly. Enjoy (best to download the High Quality WMV): Don McCrady - Parallelism in C++ Using the Concurrency Runtime Stephen Toub - Implementing Parallel Patterns using .NET 4 To get notified on future videos on parallelism (or to browse the archive) stay tuned on this channel9 parallel computing feed.

  • IOUC Summit: Open Arms and Cheese Shoes

    - by Justin Kestelyn
    Last week's International Oracle User Group Committee (IOUC) Summit at Oracle HQ was a high point of the past year, for a number of reasons: A "quorum" of Java User Group leaders, several Java Champions among them, were in attendance (Bert Breeman, Stephan Janssen, Dan Sline, Stephen Chin, Bruno Souza, Van Riper, and others), and it was great to get face time with them. Their guidance and advice about JavaOne and other things are always much appreciated. Mix in some Oracle ACE Directors (Debra Lilley, Dan Morgan, Sten Vesterli, and others), and you really have the making of a dynamic group. Stephan describes it best: "We (the JUG Leaders) discovered that behind the more formal dress code the ACE directors are actually as crazy as we are." (See link below for more.) Thanks to Bert's (NLJug) kindness, I am now the proud owner of a bonafide, straight-from-the-NL cheese shoe. How the heck did he get this through security? I suggest that you also read more robust reports from Stephan, Arun Gupta, and of course "Team Stanley."
