  • Velocity sort XML file with dynamic-elements

    - by shr_deadman
    Let's say I have a XML file wich looks like this: <root> <dynamic-element name='name' type='text' repeatable='true'> <dynamic-element name='prename' type='text' repeatable='false'> </dynamic element> </dynamic-element> </root> In Liferay the XML file will be filled with input. At the and I will have multiple $name-elements. The question is how I can sort the elements before I print them out with #foreach ($name in $name.getSiblings()) $name.prename.getData() $name.getData() #end thanks, Matthew

  • Security Resources Defining, Static/Dynamic

    - by mmontalvo
    I am implementing a simple(hopefully) security manager within an application. Is it better to have predefined(static) roles, custom roles(dynamic)? I am leaning more towards dynamic groups or roles only because then it would not require a redeploy to update the system. Also, what would be the best approach to define resources in general? The application has a database that can hold either the static or dynamic values.

  • How to create several records in only one dynamic form?

    - by Fernando
    Hi experts, please help me with a simple PHP doubt. I have a simple form: < form action="foo" Person: < a href="javascript:addmore();"Add More < /form Every time the user clicks Add More two new input fields will be dynamically created using jQuery. This can be done several times in a same form. < form action="foo" Person: < a href="javascript:addmore();"Add More < /form Each pair (name and last_name) should create on record in my db. Two Questions: 1) What is the best option for input id? Appending a counter is the best option? 2) How can I handle it in the backend using php? Let me know if you need more info. Thanks in advance.

  • Running out of memory when getting a bitmap from a server?

    - by ikky
    Hi! I'm making an application which uses MANY images. The application gets the images from a server, and downloads them one at a time. After many images the creation of a bitmap returns an exception, but i don't know how to solve this. Here is my function for downloading the images: public static Bitmap getImageFromWholeURL(String sURL) { HttpWebRequest myRequest = (HttpWebRequest)WebRequest.Create(sURL); myRequest.Method = "GET"; // If it does not exist anything on the url, then return null try { HttpWebResponse myResponse = (HttpWebResponse)myRequest.GetResponse(); System.Drawing.Bitmap bmp = new System.Drawing.Bitmap(myResponse.GetResponseStream()); myResponse.Close(); return bmp; } catch (Exception e) { return null; } } Can anyone help me out here? Thanks in advance!

  • How do you detach an array of strings from shared memory? C

    - by Tim
    I have: int array_id; char* records[10]; // get the shared segment if ((array_id = shmget(IPC_PRIVATE, 1, 0666)) == -1) { perror("Array Creating"); } // attach records[0] = (char*) shmat(array_id, (void*)0, 0); if ((int) *records == -1) { perror("Array Attachment"); } which works fine, but when i try and detach i get an "invalid argument" error. // detach int error; if( (error = shmdt((void*) records[0])) == -1) { perror(array detachment); } any ideas? thank you

  • Dynamic-linked DLL needs to share a global variable with its caller.

    - by Fabian Wickborn
    I have a static library libStatic that defines a global variable like this Header file libStatic/globals.h: extern int globvar; Code file libStatic/globals.cpp: int globvar = 42; The DLL libDynamic and the executable runner are using this global variable. Furtheron, libDynamic is linked at run-time into runner (via LoadLibrary(), GetProcAddress(), and the works...) I understand this will lead to globvar being created twice, once in the heap of runner and once in the heap of libDynamic, which is of course very undesirable. Is there a good away around this? How can I ensure that libDynamic and runner are using the same globvar?

  • pointer to preallocated memory as an input parameter and have the function fill it

    - by djones2010
    test code: void modify_it(char * mystuff) { char test[7] = "123456"; //last element is null i presume for c style strings here. //static char test[] = "123123"; //when i do this i thought i should be able to gain access to this bit of memory when the function is destroyed but that does not seem to be the case. //char * test = new char[7]; //this is also creating memory on stack and not the heap i reckon and gets destroyed once the function is done with. strcpy_s(mystuff,7,test); //this does the job as long as memory for mystuff has been allocated outside the function. mystuff = test; //this does not work. I know with c style strings you can't just do string assignments they have to be actually copied. in this case I was using this in conjunction with static char test thinking by having it as static the memory would not get destroyed and i can then simply point mystuff to test and be done with it. i would later have address the memory cleanup in the main function. but anyway this never worked. } int main(void) { char * mystuff = new char [7]; //allocate memory on heap where the pointer will point cool(mystuff); std::string test_case(mystuff); std::cout<<test_case.c_str(); //this is the only way i know how to use cout by making it into a string c++ string. delete [] mystuff; return 0; } in the case, of a static array in the function why would it not work. in the case, when i allocated memory using new in the function does it get created on the stack or heap? in the case, i have string which needs to be copied into a char * form. everything i see usually requires const char* instead of just char*. I know i could use reference to take care of this easy. Or char ** to send in the pointer and do it that way. But i just wanted to know if I could do it with just char *. Anyway your thoughts and comments plus any examples would be very helpful.

  • What's in-memory database technology that do realtime materialized view?

    - by KA100
    What I'm looking for is something like materialized views in front-end that shows my data in diffident ways without full recalculation. let's say I have stock watcher with many front-end views and dashborads some based on aggregation, order by or just filter with different criteria defined realtime by user. Now, I receive online record updates from some webservice and it's not like "data warehouse" every single record can be updated any time and it actually happens every second. Is there any technology can help me in such I create something like materialized view and it's update it without doing full recalculation every time data changed. Thank you.

  • Iterating over a large data set in long running Python process - memory issues?

    - by user1094786
    I am working on a long running Python program (a part of it is a Flask API, and the other realtime data fetcher). Both my long running processes iterate, quite often (the API one might even do so hundreds of times a second) over large data sets (second by second observations of certain economic series, for example 1-5MB worth of data or even more). They also interpolate, compare and do calculations between series etc. What techniques, for the sake of keeping my processes alive, can I practice when iterating / passing as parameters / processing these large data sets? For instance, should I use the gc module and collect manually? Any advice would be appreciated. Thanks!

  • Dynamic connection for LINQ to SQL DataContext

    - by Steve Clements
    If for some reason you need to specify a specific connection string for a DataContext, you can of course pass the connection string when you initialise you DataContext object.  A common scenario could be a dev/test/stage/live connection string, but in my case its for either a live or archive database.   I however want the connection string to be handled by the DataContext, there are probably lots of different reasons someone would want to do this…but here are mine. I want the same connection string for all instances of DataContext, but I don’t know what it is yet! I prefer the clean code and ease of not using a constructor parameter. The refactoring of using a constructor parameter could be a nightmare.   So my approach is to create a new partial class for the DataContext and handle empty constructor in there. First from within the LINQ to SQL designer I changed the connection property to None.  This will remove the empty constructor code from the auto generated designer.cs file. Right click on the .dbml file, click View Code and a file and class is created for you! You’ll see the new class created in solutions explorer and the file will open. We are going to be playing with constructors so you need to add the inheritance from System.Data.Linq.DataContext public partial class DataClasses1DataContext : System.Data.Linq.DataContext    {    }   Add the empty constructor and I have added a property that will get my connection string, you will have whatever logic you need to decide and get the connection string you require.  In my case I will be hitting a database, but I have omitted that code. public partial class DataClasses1DataContext : System.Data.Linq.DataContext {    // Connection String Keys - stored in web.config    static string LiveConnectionStringKey = "LiveConnectionString";    static string ArchiveConnectionStringKey = "ArchiveConnectionString";      protected static string ConnectionString    {       get       {          if (DoIWantToUseTheLiveConnection) {             return global::System.Configuration.ConfigurationManager.ConnectionStrings[LiveConnectionStringKey].ConnectionString;          }          else {             return global::System.Configuration.ConfigurationManager.ConnectionStrings[ArchiveConnectionStringKey].ConnectionString;          }       }    }      public DataClasses1DataContext() :       base(ConnectionString, mappingSource)    {       OnCreated();    } }   Now when I new up my DataContext, I can just leave the constructor empty and my partial class will decide which one i need to use. Nice, clean code that can be easily refractored and tested.   Share this post :

  • integration of dynamic forms for 3rd party web apps

    - by afr0
    I've a custom web forms definition interface where I user can define bespoke web forms and those webforms are then rendered on the other part of the my web app. It works well as I can render and submit my forms dynamically. However I have a scenario where there will be different 3rd party apps should be interacting with my custom forms. So the quesion arises how can I have my client side web forms and the fields within to work with the 3rd party interfaces on the fly. Any idea in that regard or best practice will be highly appreciated.

  • Language Club – Battle of the Dynamic Languages

    - by Ben Griswold
    After dedicating the last eight weeks to learning Ruby, it’s time to move onto another language.  I really dig Ruby.  I really enjoy its dynamism and expressiveness and always-openness and it’s been the highlight of our coding club for me so far. But that’s just my take on the language.  I know a lot of coders who’s stomachs turn with the mere thought of Ruby.  They say it’s Ruby’s openness which has them feeling uneasy.  I’d say “write a bunch of tests and get over it,” but I figure there must be more to it than always open classes and possible method collisions. Yes, there’s something else to it alright. The folks who didn’t fall head over heals for Ruby are already in love with Python.  You might remember that Python was the first language we tackled in our coding club.  My time with Python was okay but it didn’t feel as natural to me as Ruby.  But let’s say we started with Ruby and then moved onto Python.  Would I see Python in a different light right now.  Might I even prefer Python over Ruby?  I suppose it’s possible but it’s pretty tough to test that theory – unless we visit Python for a second time. That’s right. The language club is going to focus on Python again and in my attempt to learn Python – yet again – in the open, I’ll be posting my solutions here just as I did for Ruby.  We don’t always have second chances so I going about this relearning with two primary goals in mind:  First, I’m going to use IronPython and the IronPython tools which provide a Python code editor, a file-based project system, and an interactive Python interpreter, all inside Visual Studio 2010.  As a note, the IronPython tools are now part of the main IronPython installer which is Version 2.7 Alpha 1 (not the latest stable version, 2.6.1) and I’d be crazy not to use them.  Second, I’d like to make sure I’m still learning Python without a complete MS skew so I’m going to run my code through Eclipse using the PyDev plugin as well.  Heck, I might use IDLE too. I already have this setup on my machine so it’s no big deal. Okay, that’s it for now.  I worked on the first ten Euler problems last night and the solutions will be posted shortly. Wish me luck.

  • Dynamic meta description and keyword tags for your MasterPages

    - by Aamir Hasan
     Today we're going to look at a technique for dynamically inserting meta tags into your master pages. By taking control of the head tag and inserting your own HtmlMeta you can easily customise these tags.Might have noticed that when you create a new master page in visual studio your <head> tag gets decorated with a runat="server" attribute.Asp.net doesn't add this kind of decoration to any other html tags (although you are free to add it if you want). So what makes the head tag special?By adding the runat="server" you're giving actually converting the control into a HtmlHead control. That doesn't particularly matter for this tutorial other than to note that given a reference to the head control you get all the extras that come with asp.net controls such as access to its controls collection.The HtmlMeta control lets us wrap up <meta> tags via asp.net code. To add a meta description we need to create an instance, set the name property, the content property, and then add it to the head: asp.net using (C#)protected void Page_Init(object sender, EventArgs e){  // Add meta description tag  HtmlMeta metaDescription = new HtmlMeta();  metaDescription.Name = "Description";  metaDescription.Content = "Short, unique and keywords rich page description.";  Page.Header.Controls.Add(metaDescription);   // Add meta keywords tag  HtmlMeta metaKeywords = new HtmlMeta();  metaKeywords.Name = "Keywords";  metaKeywords.Content = "selected,page,keywords";  Page.Header.Controls.Add(metaKeywords);}asp.net ( VB.NET )Protected Sub Page_Init(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Init  ' Add meta description tag  Dim metaDescription As HtmlMeta = New HtmlMeta()  metaDescription.Name = "Description"  metaDescription.Content = "Short, unique and keywords rich page description."  Page.Header.Controls.Add(metaDescription)   ' Add meta keywords tag  Dim metaKeywords As HtmlMeta = New HtmlMeta()  metaKeywords.Name = "Keywords"  metaKeywords.Content = "selected,page,keywords"  Page.Header.Controls.Add(metaKeywords)End Sub

  • Loading dynamic content and rewrite URL on Hashchange event with Jquery Mobile

    - by user3611500
    I'm building a mobile version for my website using Jquery Mobile API. The framework provides automate AJAX navigation processing. But as far as i know it require "real" pages for loading purpose. What i want to do is override the automate navigation process of it and process the hashchange on my own. But i can't not rewrite the url using window.hashChange, which is running well on my non-mobile website version : $(function () { $(window).off().hashchange(function () { if (location.hash.length > 1) { PageSelect(); } }); $(window).hashchange(); }); I just only want to take advantage on jquery mobile interfaces, i don't want anything with its automate ajax navigation stuff ! I tried to disable it using ajaxEnabled() but got no luck.
