  • Extremely slow MFMailComposeViewControllerDelegate

    - by Jeff B
    I have a bit of a strange problem. I am trying to send in-app email. I am also using Cocos2d. It works, so far as I get the mail window and I can send mail, but it is extremely slow. It seems to only accept touches every second or so. I checked the cpu usage, and it is quite low. I paused my director, so nothing else should be happening. Any ideas? I am pulling my hair out. I looked at some examples and did the following: Made my scene the mail delegate: @interface MyLayer : CCLayer <MFMailComposeViewControllerDelegate> { ... } And implemented the following function in the scenes: -(void) showEmailWindow: (id) sender { [[CCDirector sharedDirector] pause]; MFMailComposeViewController *picker = [[MFMailComposeViewController alloc] init]; picker.mailComposeDelegate = self; [picker setSubject: @"My subject here"]; NSString *emailBody = @"<h1>Here is my email!</h1>"; [picker setMessageBody:emailBody isHTML:YES]; [myMail presentModalViewController:picker animated:NO]; [picker release]; } I also implemented the mailComposeController, to handle the callback.

  • Correctly use dependency injection

    - by Rune
    Me and two other colleagues are trying to understand how to best design a program. For example, I have an interface ISoda and multiple classes that implement that interface like Coke, Pepsi, DrPepper, etc.... My colleague is saying that it's best to put these items into a database like a key/value pair. For example: Key | Name -------------------------------------- Coke | my.namespace.Coke, MyAssembly Pepsi | my.namespace.Pepsi, MyAssembly DrPepper | my.namespace.DrPepper, MyAssembly ... then have XML configuration files that map the input to the correct key, query the database for the key, then create the object. I don't have any specific reasons, but I just feel that this is a bad design, but I don't know what to say or how to correctly argue against it. My second colleague is suggesting that we micro-manage each of these classes. So basically the input would go through a switch statement, something similiar to this: ISoda soda; switch (input) { case "Coke": soda = new Coke(); break; case "Pepsi": soda = new Pepsi(); break; case "DrPepper": soda = new DrPepper(); break; } This seems a little better to me, but I still think there is a better way to do it. I've been reading up on IoC containers the last few days and it seems like a good solution. However, I'm still very new to dependency injection and IoC containers, so I don't know how to correctly argue for it. Or maybe I'm the wrong one and there's a better way to do it? If so, can someone suggest a better method? What kind of arguments can I bring to the table to convince my colleagues to try another method? What are the pros/cons? Why should we do it one way? Unfortunately, my colleagues are very resistant to change so I'm trying to figure out how I can convince them.

  • Handling element collisions on importing/including XML schemas

    - by eggyal
    Given schema definitions that define the same element differently, can one import/include both definitions and reference them independently from within a third schema definition? For example, given: <schema xmlns="http://www.w3.org/2001/XMLSchema" targetNamespace="urn:example:namespace"> <element name="message" type="boolean"/> </schema> and: <schema xmlns="http://www.w3.org/2001/XMLSchema" targetNamespace="urn:example:namespace"> <element name="message" type="date"/> </schema> Can one construct the following: <schema xmlns="http://www.w3.org/2001/XMLSchema" targetNamespace="urn:example:namespace"> <complexType name="booleanMessageType"> <xs:sequence> <!-- reference to first definition here --> </xs:sequence> </complexType> <complexType name="dateMessageType"> <xs:sequence> <!-- reference to second definition here --> </xs:sequence> </complexType> </schema>

  • Blueprint CSS & Boks: strange behavior with prepend and append in FF and Chrome

    - by Shyam
    Hi, I am working a bit with Blueprint CSS framework and I stumbled upon Boks. I am pretty unfamiliar with the BPCSS framework, but it seems that when using prepend and append, Firefox and Chrome (both) are not liking the input. I generated the code from Boks and for my newbe eye-sight, I can't directly see what went wrong in the export. Even though the span-sizes are correct, they are mutated :S Please help me! <div class="container showgrid"> <!-- first row --> <div class="span-3 prepend-2" id="bar-menuitems"> </div> <div class="span-6 prepend-4" id="banner-logo"> </div> <div class="span-3 prepend-4 append-2 last" id="bar-socialmedia"> </div> <!-- second row --> <div class="clear span-20 prepend-2 append-2 last" id="pane-graphics"> </div> <!-- third row --> <div class="clear span-5 prepend-2" id="banner-xx1"> </div> <div class="span-5" id="banner-xx2"> </div> <div class="span-5" id="banner-xx3"> </div> <div class="span-5 append-2 last" id="banner-xx4"> </div> <!-- last row --> <div class="clear span-6 prepend-9 append-9 last" id="bar-footer"> </div> </div>

  • Use of for_each on map elements

    - by Antonio
    I have a map where I'd like to perform a call on every data type object member function. I yet know how to do this on any sequence but, is it possible to do it on an associative container? The closest answer I could find was this: Boost.Bind to access std::map elements in std::for_each. But I cannot use boost in my project so, is there an STL alternative that I'm missing to boost::bind? If not possible, I thought on creating a temporary sequence for pointers to the data objects and then, call for_each on it, something like this: class MyClass { public: void Method() const; } std::map<int, MyClass> Map; //... std::vector<MyClass*> Vector; std::transform(Map.begin(), Map.end(), std::back_inserter(Vector), std::mem_fun_ref(&std::map<int, MyClass>::value_type::second)); std::for_each(Vector.begin(), Vector.end(), std::mem_fun(&MyClass::Method)); It looks too obfuscated and I don't really like it. Any suggestions?

  • UITableView and SearchBar problem

  • How do I build BugTrap?

    - by magnifico
    I am trying to build the Itellesoft BugTrap source using Visual Studio 2008. I have downloaded and unziped the BugTrap source and the zlib source. I navigated down to ./BugTrap/Win32/BugTrap and opened BugTrap.sln (suggest by the author here). I used Build-Build Solution and the build failed with a compiler error: fatal error C1083: Cannot open include file: 'zip.h': No such file or directory I opened the project properties and added the path to the zlib-vc/zlib/include folder to the list of "Additional Include Directories" and tried to build again. The second build attempt failed with a linker error: fatal error LNK1104: cannot open file 'zlibSD.lib' I opened the zlib project and built the source. The zlib build succeeded. However, the bin directory does not contain a zlibSD.lib. The closest file in name is zlibMSD.lib. This poster on CodeProject seemed to have the same problem I did. But there is no resolution posted. Hopefully someone out there has experience building this project and can point me in the right direction, I've played with the binary distribution and it seems really slick.

  • Circle drawing with SVG's arc path

    - by ????
    The following SVG path can draw 99.99% of a circle: (try it on http://jsfiddle.net/DFhUF/46/ and see if you see 4 arcs or only 2, but note that if it is IE, it is rendered in VML, not SVG, but have the similar issue) M 100 100 a 50 50 0 1 0 0.00001 0 But when it is 99.99999999% of a circle, then nothing will show at all? M 100 800 a 50 50 0 1 0 0.00000001 0 And that's the same with 100% of a circle (it is still an arc, isn't it, just a very complete arc) M 100 800 a 50 50 0 1 0 0 0 How can that be fixed? The reason is I use a function to draw a percentage of an arc, and if I need to "special case" a 99.9999% or 100% arc to use the circle function, that'd be kind of silly. Again, a test case on jsfiddle using RaphaelJS is at http://jsfiddle.net/DFhUF/46/ (and if it is VML on IE 8, even the second circle won't show... you have to change it to 0.01) Update: This is because I am rendering an arc for a score in our system, so 3.3 points get 1/3 of a circle. 0.5 gets half a circle, and 9.9 points get 99% of a circle. But what if there are scores that are 9.99 in our system? Do I have to check whether it is close to 99.999% of a circle, and use an arc function or a circle function accordingly? Then what about a score of 9.9987? Which one to use? It is ridiculous to need to know what kind of scores will map to a "too complete circle" and switch to a circle function, and when it is "a certain 99.9%" of a circle or a 9.9987 score, then use the arc function.

  • Differences between iPhone/iPod Simulator and Devices

    - by Allisone
    Hi, since I started iPhone/iPod Development I have come across some differences between how the simulator and how real device react. Maybe I will come across some other differences I will have to figure out as well, maybe other people haven't met these problems here (YET) and can profit from the knowledge, and maybe you know some problems/differences that you would have been happy to know about earlier before you spent several hours or days figuring out what the heck is going on. So here is what I came across. Simulator is not case sensitive, Devices are case sensitive. This means a default.png or Icon.png will work in simulator, but not on a device where they must be named Default.png and icon.png (if it's still not working read this answer) Simulator has different codecs to play audio and video If you use f.e. MPMoviePlayerController you might play certain video on the simulator while on the device it won't work (use Handbrake-presets-iPhone & iPod Touch to create playable videos for Simulator and Device). If you play audio with AudioServicesPlaySystemSound(&soundID) you might here the sound on simulator but not an a device. (use Audacity to open your soundfile, export as wav and run afconvert -f caff -d LEI16@44100 -c 1 audacity.wav output.caf in terminal) Also there is this flickering on second run problem which can be resolved with an playerViewCtrl.initialPlaybackTime = -1.0; either on the end of playing or before each beginning. Simulator is mostly much faster cause it doesn't simulate the hardware but uses Mac resources, therefore f.e. sio2 Apps (OpenGL,OpenAL,etc. framework) run much better on simulator, well everything that uses more resources will run visibly better in simulator than on device. I hope we can add some more to this.

  • Sudden issues reading uncompressed video using opencv

    - by JohnSavage
    I have been using a particular pipeline to process video using opencv to encode uncompressed video (fourcc = 0), and opencv python bindings to then open and work on these files. This has been working fine for me on OpenCV 2.3.1a on Ubuntu 11.10 until just a few days ago. For some reason it currently is only allowing me to read the first frame of a given file the first time I open that file. Further frames are not read, and once I touch the file once with my program, it then cannot even read the first frame. More detail: I created the uncompressed video files as follows: out_video.open(out_vid_name, 0, // FOURCC = 0 means record raw fps, Size(640, 480)) Again, these videos worked fine for me until about a week ago. Now, when I try to open one of these I get the following message (from what I think is ffmpeg): Processing video.avi Using network protocols without global network initialization. Please use avformat_network_init(), this will become mandatory later. [avi @ 0x29251e0] parser not found for codec rawvideo, packets or times may be invalid. It reads and displays the first frame fine, but then fails to read the next frame. Then, when I try to run my code on the same video, the capture still opens with the same message as above. However, it cannot even read the very first frame. Here is the code to open the capture: self.capture = cv2.VideoCapture(filename) if not self.capture.isOpened() print "Error: could not open capture" sys.exit() Again, this part is passed without any issue, but then the break happens at: success, rgb = self.capture.read() if not success: print "error: could not read frame" return False This part breaks at the second frame on the first run of the video file, and then on the first frame on subsequent runs. I really don't know where to even begin debugging this. Please help!

  • Optimizing mathematics on arrays of floats in Ada 95 with GNATC

    - by mat_geek
    Consider the bellow code. This code is supposed to be processing data at a fixed rate, in one second batches, It is part of an overal system and can't take up too much time. When running over 100 lots of 1 seconds worth of data the program takes 35 seconds; or 35%. How do I improce the code to get the processing time down to a minimum? The code will be running on an Intel Pentium-M which is a P3 with SSE2. package FF is new Ada.Numerics.Generic_Elementary_Functions(Float); N : constant Integer := 820; type A is array(1 .. N) of Float; type A3 is array(1 .. 3) of A; procedure F(state : in out A3; result : out A3; l : in A; r : in A) is s : Float; t : Float; begin for i in 1 .. N loop t := l(i) + r(i); t := t / 2.0; state(1)(i) := t; state(2)(i) := t * 0.25 + state(2)(i) * 0.75; state(3)(i) := t * 1.0 /64.0 + state(2)(i) * 63.0 /64.0; for r in 1 .. 3 loop s := state(r)(i); t := FF."**"(s, 6.0) + 14.0; if t > MAX then t := MAX; elsif t < MIN then t := MIN; end if; result(r)(i) := FF.Log(t, 2.0); end loop; end loop; end;

  • How can one setup a version control system on a local network, without a server?

    - by Andrew
    Edit: Ok so I learned that I guess I need an distributed source control, however are there any UI based ones, and do they allow you to merge with other users on the network? This is kind of a two part question, so here it goes. I want to start developing a web application at home (with multiple developers). However, I don't have a dedicated server nor want to pay for on. So first, I don't know which version control system to use for this case, as at work we mostly have TFS setup, so I am not to familiar with whats out there. What are the best free CVS/SVN tools out there? Second, is it possible to somehow setup the CVS/SVN where there is no dedicated server and both clients store up to one week of the source code from the last check-in? Also, it would be helpful if it could integrate with visual studio, again this isn't that important at all. Problem: There are Five users, one is a Server. Server Connected: All Ok Server Disconnected: No one can share. What I am looking for: No Server: Users still have versioning based on version id of last check-in. Users must check all version on network to make sure they aren't outdated based on their last version id. If not check-in, otherwise merge/get latest. If they are update checkin, and set current version id +1.

  • HttpModule.Init - safely add HttpApplication.BeginRequest handler in IIS7 integrated mode

    - by Paul Smith
    My question is similar but not identical to: http://stackoverflow.com/questions/1123741/why-cant-my-host-softsyshosting-com-support-beginrequest-and-endrequest-event (I've also read the mvolo blog referenced therein) The goal is to successfully hook HttpApplication.BeginRequest in the IHttpModule.Init event (or anywhere internal to the module), using a normal HttpModule integrated via the system.webServer config, i.e. one that doesn't: invade Global.asax or override the HttpApplication (the module is intended to be self-contained & reusable, so e.g. I have a config like this): <system.webServer> <validation validateIntegratedModeConfiguration="false"/> <modules> <remove name="TheHttpModule" /> <add name="TheHttpModule" type="Company.HttpModules.TheHttpModule" preCondition="managedHandler" /> So far, any strategy I've tried to attach a listener to HttpApplication.BeginRequest results in one of two things, symptom 1 is that BeginRequest never fires, or symptom 2 is that the following exception gets thrown on all managed requests, and I cannot catch & handle it from user code: Stack Trace: [NullReferenceException: Object reference not set to an instance of an object.] System.Web.PipelineModuleStepContainer.GetEventCount(RequestNotification notification, Boolean isPostEvent) +30 System.Web.PipelineStepManager.ResumeSteps(Exception error) +1112 System.Web.HttpApplication.BeginProcessRequestNotification(HttpContext context, AsyncCallback cb) +113 System.Web.HttpRuntime.ProcessRequestNotificationPrivate(IIS7WorkerRequest wr, HttpContext context) +616 Commenting out app.BeginRequest += new EventHandler(this.OnBeginRequest) in Init stops the exception of course. Init does not reference the Context or Request objects at all. I have tried: Removed all references to HttpContext.Current anywhere in the project (still symptom 1) Tested removing all code from the body of my OnBeginRequest method, to ensure the problem wasn't internal to the method (= exception) Sniffing the stack trace and only calling app.BeginRequest+=... when if the stack isn't started by InitializeApplication (= BeginRequest not firing) Only calling app.BeginRequest+= on the second pass through Init (= BeginRequest not firing) Anyone know of a good approach? Is there some indirect strategy for hooking Application_Start within the module (seems unlikely)? Another event which a) one can hook from a module's constructor or Init method, and b) which is subsequently a safe place to attach BeginRequest event handlers? Thanks much

  • Why is my logic not working correctly for SPOJ TOPOSORT?

    - by Kavish Dwivedi
    The given problem is http://www.spoj.com/problems/TOPOSORT/ The output format is particularly important as : Print "Sandro fails." if Sandro cannot complete all his duties on the list. If there is a solution print the correct ordering, the jobs to be done separated by a whitespace. If there are multiple solutions print the one, whose first number is smallest, if there are still multiple solutions, print the one whose second number is smallest, and so on. What I am doing is simply doing dfs by reversing the edges i.e if job A finishes before job B, there is a directed edge from B to A . I am maintaining the order by sorting the adjacency list I created and storing the nodes which don't have any constraints separately so as to print them later in correct order . There are two flag arrays used , one for marking discovered node and one for marking the node whose all neighbors have been explored. Now my solution is http://www.ideone.com/QCUmKY (the important function is the visit funtion ) and its giving WA after running correct for 10 cases so its really hard to figure out where am I doing it wrong since it runs for all of the test cases which I have done by hand.

  • Basic jUnit Questions

    - by Epitaph
    I was testing a String multiplier class with a multiply() method that takes 2 numbers as inputs (as String) and returns the result number (as String) `public String multiply(String num1, String num2); I have done the implementation and created a test class with the following test cases involving the input String parameter as 1) valid numbers 2) characters 3) special symbol 4) empty string 5) Null value 6) 0 7) Negative number 8) float 9) Boundary values 10) Numbers that are valid but their product is out of range 11) numbers will + sign (+23) 1) I'd like to know if "each and every" assertEquals() should be in it's own test method? Or, can I group similar test cases like testInvalidArguments() to contains all asserts involving invalid characters since ALL of them throw the same NumberFormatException ? 2) If testing an input value like character ("a"), do I need to include test cases for ALL scenarios? "a" as the first argument "a" as the second argument "a" and "b" as the 2 arguments 3) As per my understanding, the benefit of these unit tests is to find out the cases where the input from a user might fail and result in an exception. And, then we can give the user with a meaningful message (asking them to provide valid input) instead of an exception. Is that the correct? And, is it the only benefit? 4) Are the 11 test cases mentioned above sufficient? Did I miss something? Did I overdo? When is enough? 5) Following from the above point, have I successfully tested the multiply() method?

  • Simplest possible voting/synchronization algorithm

    - by Domchi
    What would be a simplest algorithm one or more people could use to decide who of them should perform some task? There is one task, which needs to be done only once, and one or more people. People can speak, that is, send messages one to another. Communication must be minimal, and all people use the exact same algorithm. One person saying "I'm doing it" is not good enough since two persons may say it at a same time. Simplest that comes to my mind is that each person says a number and waits a bit. If somebody responds in that time, the person with lower number "wins" and does the task. If nobody responds, person says that she's doing it and does it. When she says that she does it, everybody else backs off. This should be enough to avoid two persons doing the task in the same time (since there is wait/handhake period), but might need a "second round" if both persons say the same number. Is there something simpler? For those curious, I'm trying to synchronize several copies of SecondLife LSL script to do something only once.

  • DWM and painting unresponsive apps

    - by Doug Kavendek
    In Vista and later, if an app becomes unresponsive, the Desktop Window Manager is able to handle redrawing it when necessary (move a window over it, drag it around, etc.) because it has kept a pixel buffer for it. Windows also tries to detect when an app has become unresponsive after some timeout, and tries to make the best of the situation -- I believe it dims out the window, adds "Not Responding" to its title bar, and perhaps some other effects. Now, we have a skinned app that uses window regions and layered windows, and it doesn't play well with these effects. We've been developing on XP, but have noticed a strange effect when testing on Vista. At some points the app may spend a few moments on some calculation or callback, and if it passes the unresponsive threshold (I've read that it's a five second timeout, but I cannot find a link), a strange graphical problem occurs: any pixels that would be 100% transparent due to the window regions turn black, which effectively makes the window rectangular again, with a black background. There seem to be other anomalies, with the original window's pixels being shifted a bit in some child dialogs. I am working on reducing such delays (ideally Windows will never need to step in like this), and trying to maintain responsiveness while it's busy, but I'd still like to figure out what is causing it to render like that, as I can't guarantee I can eliminate all delays. Basically, I just would like to know what Windows is doing when this happens, and how I can make my app behave properly with it. Skinned apps have to still work on Vista and later, so I need to figure out what I'm doing that's non-standard. I don't even know exactly how to look for information into how Windows now handles unresponsive apps, as my searches only return people having issues with apps that are unresponsive, or very rudimentary explanations of what the DWM does with such apps. Heck I'm not even 100% sure it's the DWM responsible, but it seems likely. Any potential leads? Photo of problem; screen shots won't capture the effect (note that the white dialog's buffer is shifted -- it is shifted exactly by the distance it has been offset from the main (blue) window):

  • How can I change the precision of printing with the stl?

    - by mmr
    This might be a repeat, but my google-fu failed to find it. I want to print numbers to a file using the stl with the number of decimal places, rather than overall precision. So, if I do this: int precision = 16; std::vector<double> thePoint(3); thePoint[0] = 86.3671436; thePoint[0] = -334.8866574; thePoint[0] = 24.2814; ofstream file1(tempFileName, ios::trunc); file1 << std::setprecision(precision) << thePoint[0] << "\\" << thePoint[1] << "\\" << thePoint[2] << "\\"; I'll get numbers like this: 86.36714359999999\-334.8866574\24.28140258789063 What I want is this: 86.37\-334.89\24.28 In other words, truncating at two decimal points. If I set precision to be 4, then I'll get 86.37\-334.9\24.28 ie, the second number is improperly truncated. I do not want to have to manipulate each number explicitly to get the truncation, especially because I seem to be getting the occasional 9 repeating or 0000000001 or something like that that's left behind. I'm sure there's something obvious, like using the printf(%.2f) or something like that, but I'm unsure how to mix that with the stl << and ofstream.

  • PostgreSQL - Why are some queries on large datasets so incredibly slow

    - by Brad Mathews
    Hello, I have two types of queries I run often on two large datasets. They run much slower than I would expect them to. The first type is a sequential scan updating all records: Update rcra_sites Set street = regexp_replace(street,'/','','i') rcra_sites has 700,000 records. It takes 22 minutes from pgAdmin! I wrote a vb.net function that loops through each record and sends an update query for each record (yes, 700,000 update queries!) and it runs in less than half the time. Hmmm.... The second type is a simple update with a relation and then a sequential scan: Update rcra_sites as sites Set violations='No' From narcra_monitoring as v Where sites.agencyid=v.agencyid and v.found_violation_flag='N' narcra_monitoring has 1,700,000 records. This takes 8 minutes. The query planner refuses to use my indexes. The query runs much faster if I start with a set enable_seqscan = false;. I would prefer if the query planner would do its job. I have appropriate indexes, I have vacuumed and analyzed. I optimized my shared_buffers and effective_cache_size best I know to use more memory since I have 4GB. My hardware is pretty darn good. I am running v8.4 on Windows 7. Is PostgreSQL just this slow? Or am I still missing something? Thanks! Brad

  • HttpHandler and XML files

    - by Frank
    Hello, I would like to intercept any request made to the server for XML files. I thought that it might be possible with an HttpHandler. It's coded and it works... on localhost only (?!?!). So, why is it working on localhost only? Here is my web.config <?xml version="1.0" encoding="utf-8"?> <configuration> <system.web> <httpHandlers> <add verb="*" path="*.xml" type="FooBar.XmlHandler, FooBar" /> </httpHandlers> </system.web> </configuration> Here is my C# : namespace FooBar { public class XmlHandler : IHttpHandler { public bool IsReusable { get { return false; } } public void ProcessRequest(HttpContext context) { HttpResponse Response = context.Response; Response.Write(xmlString); } } } As you might have seen, I'm writing the xmlString directly in the response, it's only temporary because I'm still wondering how I could give the filename instead (that's the second question ;) ) What is supposed to be written in the response is only the xml filename that will be retrieved by a flash app. Thanks Edit : When calling the page from another computer it looks like it's not getting to the HttpHandler.

  • Offline iOS web app: loads my manifest, but doesn't work offline

    - by Ken
    I'm writing a web app to be used offline on iOS. I've created a manifest, am serving it up as text/cache-manifest, and it usually works fine, when running inside Safari. If I add it as an app to my home screen, then turn on Airplane mode, it can't open the app at all -- I get an error and it offers to close the app. (I thought this was the entire purpose of an offline app!) When I load the app a first time when online, I can see in my logs that it's requesting every page listed in the manifest. If I turn off Airplane mode, and load the app, I can see the first file it's requesting is my main.html file (which is both listed in the manifest, and has the manifest=... attribute). It then requests the manifest, and all my other files, getting 200's for all (and 304's for anything requested a second time during this load). When I load the page in Chrome, and click around, the logs show the only thing it's trying to reach on the server is "/favicon.ico" (which is a 404, and which I don't think iOS Safari tries to load, anyway). All of the files listed in the manifest are valid and served without error. The Chrome inspector lists, under "APPLICATION CACHE", all the cached files I've listed which I expect. The entire set of files is about 50 KB, way under any limit on offline resources that I've found. Is this supposed to work, i.e., am I supposed to be able to create an offline iOS app using only HTML/CSS/JS? And where do I go about figuring out why it's failing to work offline? (Related but doesn't sound quite the same to me, since it's about Safari and not a standalone app: "Can't get a web app to work offline on iPod")

  • Using EclipseLink

    - by Ross Peoples
    I am still new to Java and Eclipse and I'm trying to get my application to connect to a database. I think I want to use EclipseLink, but all of the documentation on the matter assumes you already know everything there is to know about everything. I keep getting linked back to this tutorial: http://www.vogella.de/articles/JavaPersistenceAPI/article.html But it's basically useless because it doesn't tell you HOW to do anything. For the Installation section, it tells you to download EclipseLink and gives you a link to the download page, but doesn't tell you what to do with it after you download. The download page doesn't either. I used the "Install new software" option in Eclipse to install EclipseLink into Eclipse, but it gave me like 4 different options, none of which are explained anywhere. It gave me options JPA, MOXy, SDO, etc, but I don't know which one I need. I just installed them all. Everything on the web assumes you are already a Java guru and things that are second nature to Java devs are never explained, so it's very frustrating for someone trying to learn. So how do I install and USE EclipseLink in my project and what do I need to do to connect it to a Microsoft SQL server? Again, I am new to all of this so I have no clue what to do. Thanks for the help.

  • Jquery datatable Hidden column showing after calling another script .how can i hide the column specified permanently?

    - by Sreenath Plakkat
    My table is <table id="EmployeesTable" style="width: 100%;" class="grid-table06 border-one"> <thead> <tr> <th width="80%" align="left" valign="middle">Name</th> <th width="20%" align="left" valign="middle">Department</th> <th>Id</th> </tr> </thead> </table> My script as follows $(function () { $(".switchDate").click(function () { var id = $(this).attr("rel"); fetchEmployeedetails(id); }); fetchEmployeedetails(@model.Id); //on load function fetchEmployeedetails(id) { $("#EmployeesTable").dataTable({ "bProcessing": true, "bServerSide": true, "sAjaxSource": "/Employees/FetchDetails?Deptid=" + id + "&thresholdLow=4&threshold=100", "sPaginationType": "full_numbers", "bDestroy": true, "aaSorting": [[1, 'desc']], "asStripClasses": ['color01', 'color03'], "aoColumnDefs": [{ "aTargets": [2], "bVisible": false }, { "aTargets": [1], "fnRender": function (oObj) { return "<a href='#showemployees' rel='" + oObj.aData[2] + "'></a>"; } }] }); } }); On load it works fine not showing the hidden "Id" column but in case when I choose the id by switchDate on click function it causes the hidden column to be visible for second. How can I hide the column permanently?

  • Node.js running under IIS Express Keeps Crashing

    - by PazoozaTest Pazman
    I recently resinstalled Windows 7 on my machine and went back to downloading and installing the tools to help me continue developing node.js windows azure web applications. I followed the instructions given on the node.js azure site: http://www.windowsazure.com/en-us/develop/nodejs/ and using web installer 4.0 it says I have successfully installed these tools: Windows Azure Powershell Windows Azure SDK for Node.js - June 2012 Windows Azure SDK for .Net (VS 2012 RC) - June 2012 IIS Recommend Configuration The problem I am experiencing is that when I run the site using powershell e.g: start-azureemulator -launch it goes ahead and runs IIS Express, and after several minutes IIS Express crashes with the following information: Problem signature: Problem Event Name: APPCRASH Application Name: iisexpress.exe Application Version: 8.0.8298.0 Application Timestamp: 4f620349 Fault Module Name: iiscore.dll Fault Module Version: 8.0.8298.0 Fault Module Timestamp: 4f63b65c Exception Code: c0000005 Exception Offset: 00021767 OS Version: 6.1.7601.2.1.0.256.28 Locale ID: 1033 Additional Information 1: f66d Additional Information 2: f66d807b515d6b2dc6f28f66db769a01 Additional Information 3: 7b2f Additional Information 4: 7b2f6797d07ebc2c23f2b227e779722e I am running 2 instances each time, and both of them crash one after the other. Is anyone experiencing something similar and fix this issue ? Is their an upgrade I need to do ? I've run windows update but it says I've got all the latest updates etc. Can I tell the powershell cmdlet to use IIS 7 instead of IIS Express? I'm guessing its something to do with IIS Express on my machine. I did some hunting around and found this person here who experienced a similar problem: https://github.com/tjanczuk/iisnode/issues/149 I've got a cron job running every 1 second, to check if any website totals need to be updated. Could this be causing IIS Express to crash? Cheers

  • Taking the data mapper approach in Zend Framework

    - by Seeker
    Let's assume the following tables setup for a Zend Framework app. user (id) groups (id) groups_users (id, user_id, group_id, join_date) I took the Data Mapper approach to models which basically gives me: Model_User, Model_UsersMapper, Model_DbTable_Users Model_Group, Model_GroupsMapper, Model_DbTable_Groups Model_GroupUser, Model_GroupsUsersMapper, Model_DbTable_GroupsUsers (for holding the relationships which can be seen as aentities; notice the "join_date" property) I'm defining the _referenceMap in Model_DbTable_GroupsUsers: protected $_referenceMap = array ( 'User' => array ( 'columns' => array('user_id'), 'refTableClass' => 'Model_DbTable_Users', 'refColumns' => array('id') ), 'App' => array ( 'columns' => array('group_id'), 'refTableClass' => 'Model_DbTable_Groups', 'refColumns' => array('id') ) ); I'm having these design problems in mind: 1) The Model_Group only mirrors the fields in the groups table. How can I return a collection of groups a user is a member of and also the date the user joined that group for every group? If I just added the property to the domain object, then I'd have to let the group mapper know about it, wouldn't I? 2) Let's say I need to fetch the groups a user belongs to. Where should I put this logic? Model_UsersMapper or Model_GroupsUsersMapper? I also want to make use of the referencing map (dependent tables) mechanism and probably use findManyToManyRowset or findDependentRowset, something like: $result = $this->getDbTable()->find($userId); $row = $result->current(); $groups = $row->findManyToManyRowset( 'Model_DbTable_Groups', 'Model_DbTable_GroupsUsers' ); This would produce two queries when I could have just written it in a single query. I will place this in the Model_GroupsUsersMapper class. An enhancement would be to add a getGroups method to the Model_User domain object which lazily loads the groups when needed by calling the appropriate method in the data mapper, which begs for the second question. Should I allow the domain object know about the data mapper?
