  • PHP Flush: How Often and Best Practises

    - by Cory Dee
    I just finished reading this post: http://developer.yahoo.com/performance/rules.html#flush and have already implemented a flush after the top portion of my page loads (head, css, top banner/search/nav). Is there any performance hit in flushing? Is there such a thing as doing it too often? What are the best practices? If I am going to hit an external API for data, would it make sense to flush before hand so that the user isn't waiting on that data to come back, and can at least get some data before hand? Thanks to everyone in advance.

  • A Rose by Any Other Name..

    - by Geoff N. Hiten
    It is always a good start when you can steal a title line from one of the best writers in the English language.  Let’s hope I can make the rest of this post live up to the opening.  One recurring problem with SQL server is moving databases to new servers.  Client applications use a variety of ways to resolve SQL Server names, some of which are not changed easily <cough SharePoint /cough>.  If you happen to be using default instances on both the source and target SQL Server, then the solution is pretty simple.  You create (or bug the network admin until she creates) two DNS “A” records. One points the old name to the new IP address.  The other creates a new alias for the old server, since the original system name is now redirected.  Note this will redirect ALL traffic from the old server to the new server, including RDP and file share connection attempts.    Figure 1 – Microsoft DNS MMC Snap-In   Figure 2 – DNS New Host Dialog Box Both records are necessary so you can still access the old server via an alternate name. Server Role IP Address Name Alias Source 10.97.230.60 SQL01 SQL01_Old Target 10.97.230.80 SQL02 SQL01 Table 1 – Alias List If you or somebody set up connections via IP address, you deserve to have to go to each app and fix it by hand.  That is the only way to fix that particular foul-up. If have to deal with Named Instances either as a source or a target, then it gets more complicated.  The standard fix is to use the SQL Server Configuration Manager (or one of its earlier incarnations) to create a SQL client alias to redirect the connection.  This can be a pain installing and configuring the app on multiple client servers.  The good news is that SQL Server Configuration Manager AND all of its earlier versions simply write a few registry keys.  Extracting the keys into a .reg file makes centralized automated deployment a snap. If the client is a 32-bit system, you have to extract the native key.  If it is a 64-bit, you have to extract the native key and the WoW (32 bit on 64 bit host) key. First, pick a development system to create the actual registry key.  If you do this repeatedly, you can simply edit an existing registry file.  Create the entry using the SQL Configuration Manager.  You must use a 64-bit system to create the WoW key.  The following example redirects from a named instance “SQL01\SQLUtiluty” to a default instance on “SQL02”.   Figure 3 – SQL Server Configuration Manager - Native Figure 3 shows the native key listing. Figure 4 – SQL Server Configuration Manager – WoW If you think you don’t need the WoW key because your app is 64 it, think again.  SQL Server Management Server is a 32-bit app, as are most SQL test utilities.  Always create both keys for 64-bit target systems. Now that the keys exist, we can extract them into a .reg file. Fire up REGEDIT and browse to the following location:  HKLM\Software\Microsoft\MSSQLServer\Client\ConnectTo.  You can also search the registry for the string value of one of the server names (old or new). Right click on the “ConnectTo” label and choose “Export”.  Save with an appropriate name and location.  The resulting file should look something like this: Figure 5 – SQL01_Alias.reg Repeat the process with the location: HKLM\Software\Wow6432Node\Microsoft\MSSQLServer\Client\ConnectTo Note that if you have multiple alias entries, ALL of the entries will be exported.  In that case, you can edit the file and remove the extra aliases. You can edit the files together into a single file.  Just leave a blank line between new keys like this: Figure 6 – SQL01_Alias_All.reg Of course if you have an automatic way to deploy, it makes sense to have an automatic way to Un-deploy.  To delete a registry key, simply edit the .reg file and replace the target with a “-“ sign like so. Figure 7 – SQL01_Alias_UNDO.reg Now we have the ability to move any database to any server without having to install or change any applications on any client server.  The whole process should be transparent to the applications, which makes planning and coordinating database moves a far simpler task.

  • How to create makefile for Lazarus projects?

    - by Gustavo Carreno
    After doing a light search on the Lazarus site I've come to the conclusion that this question has been asked some times but I haven't found an answer, so I'll ask my SO peers. Is there a a way to create a Makefile to replicate the action of the Lazarus IDE when it compiles a project. If so I really don't mind if it's makefile.fpc or just plain makefile, I just want some pointers on how to get to it. BTW, I've tried the option to enable the Makefile on the Lazarus options. Doesn't work.

  • Having problems building Cairo on x64 CentOS

    - by Vnuk
    I've done this many times on 32 bit CentOS and everything went ok without a hitch. But now, on x64 CentOS, I can't get cairo to find pixman. Pixman 0.18.0 is installed in /usr/local/lib (which I believe is the usual location). Configure for Cairo 1.8.10 can't find it: checking for cairo's image surface backend feature... checking for pixman... no no checking whether cairo's image surface backend feature could be enabled... no (requires pixman-1 >= 0.12.0 http://cairographics.org/releases/) configure: error: mandatory image surface backend feature could not be enabled I've tried setting environment variable pixman_LIBS=/usr/local/lib but wihtout any luck. Any idea what is going wrong? Is it possible for me to see where is cairo's configure looking for pixman? Search paths or something like that?

  • Silverlight Navigation Menu

    - by Justin
    I am using the Silverlight Business Application Template. The navigation consists of a few HyperlinkButtons in a StackPanel. I would like to create a more robust navigation menu (multilevel) with dropdowns and such. Telerik has one for silverlight (http://demos.telerik.com/silverlight/#Menu/FirstLook) I don't want to use Telerik control because its too expensive and I have tons of problems with Telerik. I've Googled it but including "Navigation" in my search seems to only include results about the navigation framework. Anyway, anyone have a good example?

  • How to programmatically open the application menu in a .NET CF 2.0 application

    - by PabloG
    I'm developing an C# / .NET CF 2.0 application: it's supposed to be used with the touchscreen deactivated, then, I'm looking for a way to programmatically open the application menu (not the Windows menu). Looking here I tried to adapt the code to the .NET CF 2 but it doesn't work (no error messages neither) public const int WM_SYSCOMMAND = 0x0112; public const int SC_KEYMENU = 0xF100; private void cmdMenu_Click(object sender, EventArgs e) { Message msg = Message.Create(this.Handle, WM_SYSCOMMAND, new IntPtr(SC_KEYMENU), IntPtr.Zero); MessageWindow.SendMessage(ref msg); } Any ideas? TIA, Pablo After Hans answer, I edited the code to Message msg = Message.Create(this.Handle, WM_SYSCOMMAND, new IntPtr(SC_KEYMENU), new IntPtr(115)); // 's' key and added a submenu option as &Search, but it doesn't make any difference

  • What is the leading LINQ for JavaScript library?

    - by Tom Tresansky
    I'm looking for a JavaScript library that will allow me to query complex JSON objects using a LINQ-like syntax. A quick search found a couple of promising options that look they might offer what I need: LINQ to JavaScript and jLinq Does any one have any experience using them? What are some pros and cons? Is the performance comparable? Does the function-passing syntax of LINQ to JavaScript offer any hidden benefits (I personally find the syntax of jLinq more appealing on first glance)? What have you found lacking in either project? Did you ever try contacting the authors? How responsive were they? What project is more widely used?

  • php-curl script that saves images---actually captcha images

    - by user253530
    I have a curl class, called Curl. Let's presume i have this code: $url = 'http://www.google.com' $fields = array('q'=>'search term'); //maybe some other arguments. but let's keep it simple. $curl = new Curl(); $page = $curl->post($url,$fields); $page will have some images wich curl doesn't load them by default. I need to know how i can save a specific image without using curl. Once I use $page = $curl-post(..) I need to know how I can have that image saved without using another $curl-post(_image_location_) to get that file. The reason why need this is to save a captcha image from a form. I need to access the form and get that specific image that's being loaded. If i try to access the URL of the image, it will be a different captcha image.

  • SQL Saturday #44 Huntington Beach Recap

    What a great day. It was long and tiring, but rewarding in so many ways. On Sunday morning, I was driving home and I decided to take the Pacific Coast Highway from Huntington Beach.  It was a great chance to exhale and just enjoy the sun and smells of the beach (I really love SoCal sometimes). And for future reference for all you speakers, the beach and ocean are only 5 minutes from the SQL Saturday location.  I just could help noticing also the shocking number of high priced cars on the road (4 Bentleys, 3 Ferraris, 1 Aston Martins, 3 Maserati, 1 Rolls Royce, and 2 Lamborghinis).  It made me think about this: Price of all those cars: $ 150,000+.  Impacting the ability of people to learn: Priceless.  We have positively impacted the education, knowledge, capabilities of not only our attendees, but also all of their companies and people they might help as well.  That is just staggering and something to be immensely proud of. To all of my fellow community leaders, I salute you. So lets talk about the event Overall We had over 220 people register for the event and had 180+ people attend the event. I was shooting for the magical 200 number, but I guess it just gives us more motivation to make it even bigger and better next time. We had a few snags along the way, but what event doesnt, but I think everything turned out great. I did not hear any negative comments and heard lots of positive comments along with people asking when the next one is going to be (More on that later). Location- Golden West College We could not have asked for a better partner for the event. Herb Cohen from Golden West College was the wizard behind the curtains. From the beginning, he was our advocate to the GWC Board and was instrumental in getting our event approved. The day off, Herb was a HUGE help getting any and all logistics that we needed taken care of. In the craziness of the early morning registration crush it was a big help knowing that he and Bret Stateham (Blog | Twitter) were taking care of testing projectors in all the rooms. Anything we needed he was there and was even proactive in getting some things that I had not even thought of (i.e. a dumpster for all of our garbage). I cannot thank Herb enough along with other members of the GWC staff including Minnie Higgins of the Career and Technical Education Division office, Jack Taylor, public safety, and Ron Pryor, Tech Services Support. And last, but not least, the Wireless on campus was absolutely FANTASTIC! Some lessons learned Unless you are a glutton for punishment, as I no doubt am, you most certainly want to give yourself more than six weeks to plan the event. I am lucky that I have a very understanding wife and had a wonderful set of co-coordinators helping me out. A big thanks goes out to Phil, Marlon (Blog | Twitter), Nitin (Twitter), Thomas (Blog | Twitter), Bret (Blog | Twitter), Ben, and Laurie. Thankfully, the sponsor and speaker community was hugely supportive and we were able to fill out the entire event with speakers and sponsors. I have to say that there is not a lot that I would change after this years event. There are obviously going to be some things that we can do better or differently next time, but overall I think it was a great event and I was more than happy with the response we received from the community. Sponsors We obviously could not have put together our event without our sponsors. So certainly have to show them some love. Platinum Sponsors Quest Software http://www.quest.com My Space http://www.myspace.com/ Gold Strategy Companion http://www.strategycompanion.com Silver Fusion-IO http://www.fusionio.com Bronze WestClinTech http://westclintech.com Professional Association For SQL Server http://www.sqlpass.org Attunity http://www.attunity.com Sharepoint 360 http://www.sharepoint360.com Some additional Thanks Andy Warren (Blog | Twitter) Always there to answer my question and help out when I had some issues or questions with the website. The amount of work that he and everyone else put into SQL Saturday is very amazing. What a great gift to the community! Einstein Bros. Bagels They were our Breakfast Vendor and arrived perfectly on time with yummy bagels, sweets and most importantly coffee. Luccis Deli (http://www.luccisdeli.com) Luccis was out Lunch Vendor. They were great to work with and the food was excellent. They worked with us to give us a great price. Heard lots of great comments about the lunches. Definitely not your ordinary box lunch. Moving Forward Unfortunately, the work does not end after the event. We have a few things to clear up such as surveys, sponsor stuff, presentations uploaded to the website, expense reimbursement, stuff like that. Hopefully, all that should be cleared up within the next couple weeks. After that as a group we are going to get together and decide what our next steps are. We definitely want to keep some of the momentum that we are building as a SQL Community and channel that into future SQL Saturdays and other types of community events. In the meantime, for additional training be sure to check out your local User Group and PASS. San Diego SQL Server Users Group ( http://www.sdsqlug.org/home/index.cfm ) Orange County SQL Server Users Group ( http://www.sqloc.com/ ) L.A. SQL Server Users Group ( http://www.sql.la/ ) SQL PASS ( http://www.sqlpass.org/ ) 24 Hours of PASS ( http://www.sqlpass.org/24hours/2010/ ) So stay tuned, there will be more events to come in SoCal!!Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

  • ASP.NET MVC and ASP.NET membership template provider

    - by rem
    In a standard ASP.NET MVC template application that is created by default in Visual Studio when starting a new ASP.NET MVC application there is already a built-in membership / authentication / authorization system. Using web search one can find lots of info about how to work with a built-in ASP.NET membership system, but very often this material is a bit of an old and refer to ASP.NET only, not mentioning ASP.NET MVC framework. Just for example: http://msdn.microsoft.com/en-us/library/ms998347.aspx#paght000022%5Fmembershipapis or http://www.4guysfromrolla.com/articles/091207-1.aspx To what extent all that applies to ASP.NET built-in membership system applies also to ASP.NET MVC ready template membership system?

  • Are TClientDataSets part of your toolkit, or have they been replaced by something else?

    - by Tom1952
    I have 50 or 60 records of four or five fields. I need to load the records into RAM (From a CSV file), search on different fields, enumerate, etc. Not a lot of data, not a lot of functionality. I was all excited to use the new (to me in D2010) TDictionary or TList, but thought that a TClientDataset (which I've never used before) might be more appropriate. With a TClientDataSet, I can use .Locate on any field, enumerate with while NOT CDS.EOF, etc. And, what exactly is this MidasLib that I have to use with CDS? Can I reasonably expect it to be supported in the future? Is TClientDataSet still considered state-of-the-art, or is it showing its age and somewhat deprecated (literally and figuratively)? I've seen colleagues use DX's TdxMemData. Why use it (or any of the other handful of memory datasets I've seen while googling this issue) rather than a CDS? Related question: http://stackoverflow.com/questions/274958/delphi-using-tclientdataset-as-an-in-memory-dataset

  • Querying for names

    - by Sai
    I have a table (say "Demographics") on SQL Server. In this table are the following columns "LastName", "FirstName", "MiddleName", "Prefix" , "Suffix". I have one textbox to search for them on a webpage. My question: Whats a good design strategy for queries where the user could be searching for various combinations of names including last names that have spaces e.g. "Smith James Jr." . Our customers store Jr. sometimes in suffix and sometimes just tack it to lastname. Sometimes Smith James Jr could be the entire last name.

  • Too Many Different Cell Formats

    - by Craig
    I have a massive file with 10 sheets recreated from scratch, 12 sheets updated, 5 sheets loaded with raw data, and 7 sheets that are used by the macros for the report. I have recently added a new sheet and am running into the Excel "Too many different cell formats" problem. I have read some of the google search results and they say I should simplify the formatting, but I don't even know how I got up to 4000 distinct cell formats, let alone how much I'm using which ones, so I can remove some. It is also popping up some times the file is run, but not all, until such time as it comes up, and then it happens every time it is run. Since the macro is doing so much of the work, including creating the 10 sheets from scratch, I am not sure what to do. Does anyone know of a Macro I could run to get a listing of all the cell formats and how many cells are using them? Does anyone know of a program they trust to help remove excess cell formats? Thanks, Craig

  • Is there a website to lookup common, already written functions?

    - by pinnacler
    I'm sitting here writing a function that I'm positive has been written before, somewhere on earth. It's just too common to have not been attempted, and I'm wondering why I can't just go to a website and search for a function that I can then copy and paste into my project in 2 seconds, instead of wasting my day reinventing the wheel. Sure there are certain libraries you can use, but where do you find these libraries and when they are absent, is there a site like I'm describing? Possibly a wiki of some type that contains free code that anybody can edit and improve?

  • Benefits of programming (doing) versus reading blogs (thinking?)

    - by Xian
    I have come to a conclusion or realization that perhaps many developers I know including myself have a fanatical fascination with reading as many programming and technology blogs or listening to podcasts as humanly possible. I sometimes wonder if this time would be much better spent in actual coding and doing, rather than the incessant thinking and perhaps wondering what the "other guy" is doing? With a very large signal to noise ratio in most blogs and podcasts, is there real benefit in maintaining a huge and constant blog role.. or is this some primal fear or instinct to keep up the pace unless being left behind? Can they simply be relegated to Google search and just-in-time learning? Edit: (There are some amazing answers here and touch a philosophical nerve with me, if you are reading this for the first time, I recommend taking the time reading through the answers below)

  • Add a link to a JQueryUI autocomplete item

    - by Tordek
    When a user starts typing on the searchbox, the suggestion page returns the latest item from all collections matching that nama, plus other data. I'd like to show that item (along its image), and a link to "see all items from this collection". I can do (most of) that with the following code: $('#search').autocomplete({ source: function (request, response) { $.ajax({ url: suggesturl, dataType: 'json', data: request, success: function (data) { response(data.map(function (value) { return { 'label': '<img src="' + value.thumbsmall + '" />' + value.name + '<a href="/">More items from this collection...</a>', 'value': value.fullname }; })); } }); }, minLength: 3 }) The problem is that, although the link appears in the box, when it's clicked it gets ignored, and the default select action is executed (the item's value is put into the textbox).
