  • find a specific string pattern in an array jquery

    - by Bwyss
    Apologies if this is a duplicate, but I can't seem to find the solution. I am trying to find a specific string pattern in an array. I want to find all values in data that contain 'underscore r underscore'. I then want to create a new array that contains only those keys and values. var data = ["something", "bar_r_something"]; var resultArray = new Array(); for (var i = 0; i < data.length; i++) { var bar = /_r_/; if ($.inArray(bar, data[i].length) > 0) { console.log("found _r_"); resultArray.push(data[i]); } }; I just can't seem to get that $.inArray to work, it seems to always kick out -1.

  • singleton pattern in java- lazy Intialization

    - by flash
    public static MySingleton getInstance() { if (_instance==null) { synchronized (MySingleton.class) { _instance = new MySingleton(); } } return _instance; } 1.is there a flaw with the above implementation of the getInstance method? 2.What is the difference between the two implementations.? public static synchronized MySingleton getInstance() { if (_instance==null) { _instance = new MySingleton(); } return _instance; } I have seen a lot of answers on the singleton pattern in stackoverflow but the question I have posted is to know mainly difference of 'synchronize' at method and block level in this particular case.

  • Doubt about a particular pattern of Javascript class definition

    - by fenderplayer
    Recently i saw the following code that creates a class in javascript: var Model.Foo = function(){ // private stuff var a, b; // public properties this.attr1 = ''; this.attr2 = ''; if(Model.Foo._init === 'undefined'){ Model.Foo.prototype = { func1 : function(){ //...}, func2 : function(){ //... }, //other prototype functions } } Model.Foo._init = true; } // Instantiate and use the class as follows: var foo = new Model.Foo(); foo.func1(); I guess the _init variable is used to make sure we don't define the prototypes again. Also, i feel the code is more readable since i am placing everything in a function block (so in oop-speak, all attributes and methods are in one place). Do you see any issues with the code above? Any pitfalls of using this pattern if i need to create lots of classes in a big project?

  • [Bash] Save part of matching pattern to variable

    - by Ben
    I want to extract a substring matching a pattern and save it to a file. An example string: Apr 12 19:24:17 PC_NMG kernel: sd 11:0:0:0: [sdf] Attached SCSI removable disk I want to extract the part between the brackets, in this case []. I tried to do something like grep -e '[$subtext]' to save the text in the brackets to a variable. Of course it doesn't work, but I am looking for a way similar to this. It would be very elegant to include a variable in a regex like this. What can I do best? Thanks!

  • What Design Pattern To Replace 'CurrentStep' Variable

    - by Rob P.
    Tried to search but didn't know how to phrase it. I've got some code that is essentially... Private CurMajorStep as Integer = 0 Private CurMinorStep as Integer = 0 Public Sub PerformNextStep() Select Case iMajorStep Case 0 ThingOne() Case 1 ThingTwo() Case 2 ThingThree() Case 3 ThingFour() Case 4 AnythingElse() Case 5 Finish() End Select End Sub And then, in some of those, the CurMinorStep keeps track of the current state of that particular 'step'. I hope that all makes sense. The code is messy and I know it's going to be problematic to maintain. Can someone point me to a clean OO pattern to handle this?

  • Drag and drop in as3 on specific path (ex bezier curve)

    - by abinop
    I need to implement a drag and drop functionality, where I can define and constraint the route of the draggable object. Like in http://www.kirupa.com/forum/showthread.php?t=330302 , only that i have the paths designed and not calculated by a math function. So, in fact, as mouse moves I need to tell the object to follow the custom path/movieclip.

  • iPhone OS 3.2 File Sharing Path

    - by OscarTheGrouch
    Currently I have this for my file path and file... NSURL *storeUrl = [NSURL fileURLWithPath: [[self applicationDocumentsDirectory] stringByAppendingPathComponent: @"Shared\PartyPlanner.sqlite"]]; This allows me to share the file with iTunes, but instead of just having 'PartyPlanner.sqlite' in the 'applicationDocumentsDirectory\Shared' I have "SharedPartyPlanner.sqlite" in the 'applicationDocumentsDirectory' is there a cleaner or easier way to get to the shared folder inside of applicationDocumentsDirectory?

  • Specify the search path for DllImport in .NET

    - by Stefan
    Is there a way to specify the paths to be searched for a given assembly that is imported with DllImport? [DllImport("MyDll.dll")] static extern void Func(); This will search for the dll in the app dir and in the PATH environment variable. But at times the dll will be placed elsewhere. Can this information be specified in app.config or manifest file to avoid dynamic loading and dynamic invocation?

  • Path.Combine for Urls?

    - by Brian MacKay
    Path.Combine is handy, is there a similiar function in the framework for Urls? I'm looking for syntax like this: Url.Combine("Http://MyUrl.com/", "/Images/Image.jpg") ...Which would return: "Http://MyUrl.com/Images/Image.jpg" ...Of course string concatenation would be fine here since the '//' would be handled intelligently by the browser. But it feels a little less elegant.

  • bulk insert image from relative path

    - by Markus
    Hi, I wonder if some can help me out with this little problem. I have the following insert statement: insert into symbol (sy_id, sy_fg_color, sy_bg_color, sy_icon) select 302, 0, 16245177, sy_icon = (select * from openrowset(bulk 'K:\mypath\icons\myicon.png', single_blob) as image) Is it possible to make the path relative in any way? I'm using TFS to deploy the database, so if it's not possible to make it relative with T-SQL, maybe it can be done with a little help from TFS/Visual Studio deploy?

  • Using regular expressions to remove relative path slashes

    - by Adam Carlile
    Hey Guys I am trying to remove all the relative image path slashes from a chunk of HTML that contains several other elements. For example <img src="../../../../images/upload/1/test.jpg /> would need to become <img src="http://s3.amazonaws.com/website/images/upload/1/test.jpg" /> I was thinking of writing this as a rails helper, and just passing the entire block into the method, and make using Nokogiri or Hpricot to parse the HTML instead, but I don't really know. Any help would be great Cheers Adam

  • Silverlight OOB Application Path Portability

    - by jws
    Silverlight Out-of-browser applications get installed to a seemingly random location: AppData\LocalLow\Microsoft\Silverlight\OutOfBrowser\2333572144.www.microsoft.com for example. Currently, I am simply storing this path, which works perfectly well on a single machine and a single install, but how can I refer to this application between different installations?

  • mciSendString cannot save to directory path

    - by robUK
    Hello, VS C# 2008 SP1 I have a created a small application that records and plays audio. However, my application needs to save the wave file to the application data directory on the users computer. The mciSendString takes a C style string as a parameter and has to be in 8.3 format. However, my problem is I can't get it to save. And what is strange is sometime it does and sometimes it doesn't. Howver, most of the time is failes. However, if I save directly to the C drive it works first time everything. I have used 3 different methods that I have coded below. The error number that I get when it fails is 286."The file was not saved. Make sure your system has sufficient disk space or has an intact network connection" Many thanks for any suggestins, [DllImport("winmm.dll",CharSet=CharSet.Auto)] private static extern uint mciSendString([MarshalAs(UnmanagedType.LPTStr)] string command, StringBuilder returnValue, int returnLength, IntPtr winHandle); [DllImport("winmm.dll", CharSet = CharSet.Auto)] private static extern int mciGetErrorString(uint errorCode, StringBuilder errorText, int errorTextSize); [DllImport("Kernel32.dll", CharSet=CharSet.Auto)] private static extern int GetShortPathName([MarshalAs(UnmanagedType.LPTStr)] string longPath, [MarshalAs(UnmanagedType.LPTStr)] StringBuilder shortPath, int length); // Stop recording private void StopRecording() { // Save recorded voice string shortPath = this.shortPathName(); string formatShortPath = string.Format("save recsound \"{0}\"", shortPath); uint result = 0; StringBuilder errorTest = new StringBuilder(256); // C:\DOCUME~1\Steve\APPLIC~1\Test.wav // Fails result = mciSendString(string.Format("{0}", formatShortPath), null, 0, IntPtr.Zero); mciGetErrorString(result, errorTest, errorTest.Length); // command line convention - fails result = mciSendString("save recsound \"C:\\DOCUME~1\\Steve\\APPLIC~1\\Test.wav\"", null, 0, IntPtr.Zero); mciGetErrorString(result, errorTest, errorTest.Length); // 8.3 short format - fails result = mciSendString(@"save recsound C:\DOCUME~1\Steve\APPLIC~1\Test.wav", null, 0, IntPtr.Zero); mciGetErrorString(result, errorTest, errorTest.Length); // Save to C drive works everytime. result = mciSendString(@"save recsound C:\Test.wav", null, 0, IntPtr.Zero); mciGetErrorString(result, errorTest, errorTest.Length); mciSendString("close recsound ", null, 0, IntPtr.Zero); } // Get the short path name so that the mciSendString can save the recorded wave file private string shortPathName() { string shortPath = string.Empty; long length = 0; StringBuilder buffer = new StringBuilder(256); // Get the length of the path length = GetShortPathName(this.saveRecordingPath, buffer, 256); shortPath = buffer.ToString(); return shortPath; }

  • Zend Mail - bouncing mails not returning to the specified "Return-Path"

    - by Leprosy
    Hi, i'm working on a simple mail list app in PHP using Zend Mail. The idea is that all mail that bounce is redirected to a script which processes them and a report is generated. The script is running ok in direct tests, but I've testing it with fake mail address to test the mail list app, and it appears that the mail is not being redirected to the correct email address. Zend Mail provides the setReturnPath method to set the "Return-Path" header, it's ok to use this header for this purpose? Thanks

  • Get the file path of current application's config file

    - by dummy
    The reason I asked this question is that I wanted to create a helper class for Remoting instantiation, and wanted to pass the appropriate app.exe.config (or web.config) file path to the RemotingConfiguration.Configure method, depending on the caller. Is there a way I could get the name of the config file for both Win and Web apps without checking if the application is Web or WinForms?
