  • Is a commercial licensing tool better than a home grown solution for licensing a software product.

    - by Kalpak
    Hi, We are developing a product in C#.Net. We would definately not like our product to be copied easily across machines (in short pirated). For that purpose can anybody suggest using a 3rd party tool or a home grown solution. What are the pros and cons of each. One negative about home grown solution is that the cost involved in creating one from scratch. Can somebody comment on the technology to be used for licensing as .Net can be decompiled.

  • Zend Framework, what $this->_forward is doing

    - by RageZ
    Hello everyone, I would like someone to explain me what _forward is exactly doing, I cannot see if _forward is also rendering the attached view to the action or just executing the action. Also is it possible to pass argument to $this-action in a view script ? More generally my problem is how to code a confirmation page, let's say the user input some stuff and you want to show him confirmation, is forward is mean for that case ? Thanks

  • javascript not working on localhost

    - by Adam McMahon
    Ok so I'm lost here, frustrated and pulling my hair and out. Plus probably about to be fired or take a pay cut. I moved Files from a development server to my local machine. The files are consistent (used diff tool), all the dependencies are there. It works for the most part. The problem is that the some of the javascript (not all) is just not working. We're using jquery and a lot of plugins for it. I've checked with the web developer plugin in firefox and all the js files are loading. I cleared the cache in both firefox and chrome multiple times to no avail. The development server is a windows server running wamp. My local machine is running ubuntu. Somebody tell me what I missed.

  • MySQL doesn't use index in join query

    - by Kocsonya Laci
    I have two tables: comments(id(primary key), author, ip(index)) and visitors(id(primary key), date_time, ip(index)) I want to join them like that: SELECT visitors.date_time FROM comments LEFT JOIN visitors ON ( comments.ip = visitors.ip ) WHERE comments.author = 'author' LIMIT 10 It works, but very slow.. In EXPLAIN it shows that it doesn't use the index on the visitors table: id select_type table type possible_keys key key_len ref rows Extra 1 SIMPLE comments ref author author 78 const 9660 Using where 1 SIMPLE visitors ALL NULL NULL NULL NULL 8033 Any ideas? Thanks!

  • Why is Visual Basic used?

    - by Arrieta
    I don't mean to start a holy war here, but I cannot fathom why would anybody use Visual Basic for a new project. Can you explain me why is it used? What new applications (which a lay person may be familiar with) have been developed in it? Why is it chosen over other languages? Thanks.

  • DataContractAttribute with Shared Assembly

    - by Sanju
    Hi All, Is it necessary to decorate custom objects with [DataContract] and [DataMember] when using shared assemblies (as opposed to auto proxy generation)? The reason I ask is that I have encountered the following scenario: Suppose the following object is implemented in my service: public class baseClass { Guid _guid; public baseClass() { _guid = Guid.NewGuid() } public Guid ReturnGuid { get {return _guid;}} } public class newClass : baseClass { int _someValue; public newClass {} public int SomeValue { get {return _someValue;} set {_someValue = value;} } } [ServiceContract] public IService { [OperationContract] newClass SomeOperation(); } In my client (with shared assemblie) I can happily recieve and use a serialized newClass when SomeOperation is called - even though I have not marked it as a DataContract. However, as soon as I do mark it with DataContract and use DataMember then it complains that set is not implemented on ReturnGuid in the base class. Could somebody explain why it works fine when I do not decorate with DataContract and DataMember. Many thanks.

  • Regarding Standard Oxford Format for vlfeat sift

    - by Karl
    One of my upper classmen has gave me a data set for experimenting with vlfeat's SIFT, however, her extracted SIFT data for the frame part contains 5 dimensions. Recall from vl_sift function: [F,D] = VL_SIFT(I) Each column of D is the descriptor of the corresponding frame in F. F normally contains 4 dimensions which consists of x-coordinate, y-coordinate, scale, and orientation. So I asked her what is this 5th dimension, and she pointed me to search for "standard oxford format" for sift feature. The thing is I tried to search around regarding this standard oxford format and sift feature, but I got no luck in finding it at all. If somebody knows regarding this, could you please point me to the right direction?

  • calling database driver in java app [basically a swing app]

    - by user993250
    I have made a java application that allows a user to choose from certain standards and then allows him to customize those standards according to his needs. Now, the customization [via a swing application] that has been made needs to be persistent. For this we use a database [mysql/access] and hook it to the application so that with each customization made, a table [if non-existent] is created [thus making it runtime and we can not pre-determine the table names or the keys of table etc] and an appropriate entry in the table is made. I have written the driver for this connection. How do I call it in the java application and what approach should I take? I would much appreciate that if somebody can refer me some example that not only shows a sample connection being made via driver but its appropriate calls to the database as well so that i can use it as a guide.

  • What is __path__ useful for?

    - by Jason Baker
    I had never noticed the __path__ attribute that gets defined on some of my packages before today. According to the documentation: Packages support one more special attribute, __path__. This is initialized to be a list containing the name of the directory holding the package’s __init__.py before the code in that file is executed. This variable can be modified; doing so affects future searches for modules and subpackages contained in the package. While this feature is not often needed, it can be used to extend the set of modules found in a package. Could somebody explain to me what exactly this means and why I would ever want to use it?

  • Where are Silverlight assemblies stored when a xap file is run?

    - by ForeverDebugging
    We currently have a XAP file which contains Foo.dll, and another XAP file (with a completely different name) which contains an updated version Foo.dll (but the same version number). When we run the second XAP file, it looks as though the Silverlight runtime on the client, is picking up the old version of Foo.dll from the first XAP file. Anyone know where the Silverlight runtime unzips the xap file before running its content? Or if the runtime executes on a single app domain which could explain these errors?

  • Character encoding issues in MySQL

    - by Eric
    In my database we have fields where the data is not readable. I now know why it happened but I don't know how to fix it. I found a way to get the info back from the database: SELECT id, name FROM projects WHERE LENGTH(name) != CHAR_LENGTH(name); One of the rows returned shows: id | name ------------------------- 1008 | Cajón el Diablo This should be: id | name ------------------------- 1008 | Cajón el Diablo Can somebody help me figure out how to fix this problem? How can I convert this using SQL? Is SQL not good? If not, how about Python?

  • Javascript: 'this' changes when assigning a property?

    - by Pickels
    I know 'this' can be a problem when you don't understand Javascript well but this one got me a little puzzled. var ControlTypes = { TextBox: function () { console.log(this); this.Name = "TextBox"; console.log(this); } } ControlTypes.TextBox(); Firebug gives the following result: Object {} Object { Name="TextBox"} The first object is ControlTypes and the second one is Textbox. Could anybody explain the behavior behind this?
