  • Working With Files in Dreamweaver

    Your web files have special needs because anytime you move or delete a file, it has an effect on other files that are linked to it. So, Dreamweaver also has file management tasks related to the web development environment. Dreamweaver keeps a record of all the links on your site. (Remember that the code for a photo is also a link.) Then when you move, Dreamweaver will ask if you want to update the other pages that link to that file. If you delete a file, Dreamweaver will warn you, if there are other pages using that file. Dreamweaver is actually a package of programs and one of them does the file management tasks.

  • using static methods and classes

    - by vedant1811
    I know that static methods/variables are associated with the class and not the objects of the class and are useful in situations when we need to keep count of, say the number of objects of the class that were created. Non-static members on the other hand may need to work on the specific object (i.e. to use the variables initialized by the constructor) My question what should we do when we need neither of the functionalities? Say I just need a utility function that accepts value(s) and returns a value besed solely on the values passed. I want to know whether such methods should be static or not. How is programming efficiency affected and which is a better coding practice/convention and why. PS: I don't want to spark off a debate, I just want a subjective answer and/or references.

  • Keeping application backend and UI synchronised

    - by Deanna
    Hi all. I have an app that works with a list of objects so has one central keyed list. The main window has a tree containing these object with some information, which is easy enough to populate as a one off event after loading. Now, the complicated part, any part of the application can add, remove, and more importantly change the details of those objects at any time (all in the same process) and I'd like the tree to update to suit. I have a few options including passing events back down from the object to the list to the form which seems to be the most flexible way. I can also do it lazily and repopulate the tree each time or periodically (very hackish). Does anyone have any better thoughts on how to structure this? This is being done in C# 2.0 but the concepts apply to any environment. Thanks

  • Why can't my Wifi cannot connect or disconnect?

    - by tmy1018
    Wifi connection might drop spontaneously or simply cannot connect. Users on Ubuntu 10.04 and 11.04 have reported experiencing the problem. Running dmesg would show: [210749.637705] wlan0: deauthenticating from 00:23:89:48:3b:b0 by local choice (reason=3) [210778.632244] wlan0: deauthenticating from 00:23:89:48:3b:b0 by local choice (reason=3) [210784.456359] wlan0: deauthenticating from 00:23:89:82:75:70 by local choice (reason=3) which is pretty cryptic. I have tried: kill -9 wpa_supplicant, but wpa_supplicant keeps getting restarted each time. Also, some have suggested that this was caused by enabling power management. However, this might not be true, as the problem has presented itself in a situation where power management was disabled.

  • Development Approach: User Interface In or Domain Model Out?

    - by Berin Loritsch
    While I've never delivered anything using Smalltalk, my brief time playing with it has definitely left its mark. The only way to describe the experience is MVC the way it was meant to be. Essentially, all the heavy lifting for your application is done in the business objects (or domain model if you are so inclined). The standard controls are bound to the business objects in some way. For example, a text box is mapped to an object's field (the field itself is an object so it's easy to do). A button would mapped to a method. This is all done with a very simple and natural API. We don't have to think about binding objects, etc. It just works. Yet, in many newer languages and APIs you are forced to think from the outside in. First with C++ and MFC, and now with C# and WPF, Microsoft has gotten it's developer world hooked on GUI builders where you build your application by implementing event handlers. Java Swing development isn't so different, only you are writing the code to instantiate the controls on the form yourself. For some projects, there may never even be a domain model--just event handlers. I've been in and around this model for most of my carreer. Each way forces you to think differently. With the Smalltalk approach, your domain is smart while your GUI is dumb. With the default VisualStudio approach, your GUI is smart while your domain model (if it exists) is rather anemic. Many developers that I work with see value in the Smalltalk approach, and try to shoehorn that approach into the VisualStudio environment. WPF has some dynamic binding features that makes it possible; but there are limitations. Inevitably some code that belongs in the domain model ends up in the GUI classes. So, which way do you design/develop your code? Why? GUI first. User interaction is paramount. Domain first. I need to make sure the system is correct before we put a UI on it. There's pros and cons for either approach. Domain model fits in there with crystal cathedrals and pie in the sky. GUI fits in there with quick and dirty (sometimes really dirty). And for an added bonus: How do you make sure the code is maintainable?

  • C++ game architecture

    - by rxc
    I'm trying to make a game, but I'm not sure of the best way to set up the main loop and classes. For really small games, I could put everything in the main() loop, including event handling, collision checking, etc. However, for large games, that's seems like a highly inefficient way to get things done. The architecture I want is kind like the way the Minecraft coders did it (I quote Minecraft code because I've seen the source code when downloading MCP). They have objects entity classes EntityCow and EntityChicken and they have methods like onDeath(), onLivingUpdate(); and item classes like ItemSword have methods like onItemUse(). I've never seen these methods get called directly, but apparently, they get stored in a class called DataWatcher, which, I think "watches" all the data (as the name implies) and calls the appropriate methods in the objects. Is that how most games do it? If so, how is the DataWatcher class implemented? Any help or alternate suggestions is really appreciated.

  • How do I convert a partially transparent image into polygons?

    - by user82779
    I'm using GLEE2D, a level editor allowing me to import images, scale them, rotate them, and position them onto layers and export the data into XML format. However, it does not tell me objects' boundaries. I can calculate them, but only given the original image's polygons. How do I get polygons of objects in a transparent image? An example object (I outlined it): How would I turn the object, knowing the scaled size of the image, into polygons? Is there an algorithm for this? I'll use OpenGL to draw them.

  • Disposing of ContentManager increases memory usage

    - by Havsmonstret
    I'm trying to wrap my head around how memory management works in XNA 4.0 I've created a screen management test and when I close a screen, the ContentManager created by that screen is unloaded. I have used ANTS Memory Manager to look at how the memory usage is altered when I do this, and it gives me some results which makes me scratch my head. The game starts with loading two textures (435kB and 48,3kB) which puts the usage at about 61MB. Then, when I delete the screen and runs Unload on the ContentManager, the memory usage drops to 56,5MB but instantly after goes up to 64,8MB. Am I doing something wrong or is this usual for XNA games? Do I have to dispose of everything the ContentManager loads seperatly or do I need to do something more to the ContentManager? Thanks in advance!

  • Oracle Data Protection: How Do You Measure Up? - Part 1

    - by tichien
    This is the first installment in a blog series, which examines the results of a recent database protection survey conducted by Database Trends and Applications (DBTA) Magazine. All Oracle IT professionals know that a sound, well-tested backup and recovery strategy plays a foundational role in protecting their Oracle database investments, which in many cases, represent the lifeblood of business operations. But just how common are the data protection strategies used and the challenges faced across various enterprises? In January 2014, Database Trends and Applications Magazine (DBTA), in partnership with Oracle, released the results of its “Oracle Database Management and Data Protection Survey”. Two hundred Oracle IT professionals were interviewed on various aspects of their database backup and recovery strategies, in order to identify the top organizational and operational challenges for protecting Oracle assets. Here are some of the key findings from the survey: The majority of respondents manage backups for tens to hundreds of databases, representing total data volume of 5 to 50TB (14% manage 50 to 200 TB and some up to 5 PB or more). About half of the respondents (48%) use HA technologies such as RAC, Data Guard, or storage mirroring, however these technologies are deployed on only 25% of their databases (or less). This indicates that backups are still the predominant method for database protection among enterprises. Weekly full and daily incremental backups to disk were the most popular strategy, used by 27% of respondents, followed by daily full backups, which are used by 17%. Interestingly, over half of the respondents reported that 10% or less of their databases undergo regular backup testing.  A few key backup and recovery challenges resonated across many of the respondents: Poor performance and impact on productivity (see Figure 1) 38% of respondents indicated that backups are too slow, resulting in prolonged backup windows. In a similar vein, 23% complained that backups degrade the performance of production systems. Lack of continuous protection (see Figure 2) 35% revealed that less than 5% of Oracle data is protected in real-time.  Management complexity 25% stated that recovery operations are too complex. (see Figure 1)  31% reported that backups need constant management. (see Figure 1) 45% changed their backup tools as a result of growing data volumes, while 29% changed tools due to the complexity of the tools themselves. Figure 1: Current Challenges with Database Backup and Recovery Figure 2: Percentage of Organization’s Data Backed Up in Real-Time or Near Real-Time In future blogs, we will discuss each of these challenges in more detail and bring insight into how the backup technology industry has attempted to resolve them.

  • What is the correct pattern to use in this case?

    - by nulliusinverba
    I'm sure this scenario has arisen before, and I want to know what experience has taught to be the best solution. I have a number of classes that are all of a kind. Say all the objects are "Content". They may be "Article", or "Book" for example. The reason I want the "Content" abstraction is because I want to define a number of behaviours for all "Content" objects and not have to build a new DB Table and 10 classes of essentially the same code for each type of "Content". For example, to attach a "Tag" or a "Premise" to a content object would be much nicer if, say, I just had two columns one for ContentID and one for TagID. A solution I've played around with is to have a Content table with a unique ID, and then to have foreign key references on all the other tables (Book, Article, etc). This has actually proven quite solid, but I'm just not sure about it. Do you know how to call this described pattern?

  • Entity framework architecture

    - by user1741807
    I want to make a entity framework application in Winforms C#. I'm new to entity framework, and don't know how to make the architecture. I want to have the model in a class library, and a GUI layer, and maybe a controller layer. I'm used to that architecture, but don't know have to handle the objects in other layers than the model. Have do I manage objects in the gui layer, when I can't have a reference to the model? I'm used to have some kind of dto, but what's the best way?

  • Java game applet development

    - by RomZes
    I'm getting 4 sec delay when sending objects over UDP. Working on small game and trying to implement multiplayer. For now just trying to synchronize movements of 2 balls on the screen. StartingPoint.java is my server(first player), that receiving serialized objects (coordinates). SecondPlayer.java is client that sending serialized objects to server. When I'm moving my first object it appears 4 seconds later on different screen.
