  • Android Form Design Overlaping

    - by Mashfuk
    In My Project I have to built a registration form like the following. But when I design the form it overlays some item. How can I easily design registration form in android. How can I solve this? Thanks in advanced. <?xml version="1.0" encoding="utf-8"?> <ScrollView xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/ScrollView1" android:layout_width="fill_parent" android:layout_height="fill_parent" > <RelativeLayout android:layout_width="fill_parent" android:layout_height="fill_parent" android:background="#FFFFFF" > <TextView android:text="Registration Form" android:id="@+id/textView1" android:layout_width="wrap_content" android:layout_height="wrap_content"> </TextView> <View android:layout_below="@id/textView1" android:background="#000000" android:layout_height="1dp" android:id="@+id/view1" android:layout_width="fill_parent" > </View> <!-- Child Menu Section of Registration Form --> <RelativeLayout android:layout_below="@id/textView1" android:id="@+id/rlKidsMenuRegForm" android:layout_height="wrap_content" android:layout_width="fill_parent" > <TextView android:layout_alignParentLeft="true" android:text="Do you use the kids MENU?" android:layout_height="wrap_content" android:layout_width="wrap_content" android:id="@+id/textView2"> </TextView> <EditText android:layout_toRightOf="@id/textView2" android:textSize="10sp" android:layout_height="15dp" android:text="EditText" android:id="@+id/editText1" android:layout_width="wrap_content"> </EditText> <EditText android:layout_height="wrap_content" android:text="EditText" android:textSize="10sp" android:id="@+id/editText2" android:layout_width="wrap_content" android:layout_below="@id/editText1"> </EditText> <EditText android:layout_toRightOf="@id/editText2" android:layout_below="@id/editText1" android:layout_height="wrap_content" android:textSize="10sp" android:text="EditText" android:id="@+id/editText3" android:layout_width="wrap_content"> </EditText> <View android:layout_below="@id/editText3" android:background="#000000" android:layout_height="1dp" android:id="@+id/view1" android:layout_width="fill_parent" > </View> </RelativeLayout> <!-- Mid Section of Registration Form --> <RelativeLayout android:layout_below="@id/rlKidsMenuRegForm" android:id="@+id/rlMidRegForm" android:layout_height="wrap_content" android:layout_width="fill_parent" android:background="#FFFFFF" > <EditText android:layout_alignParentLeft="true" android:layout_height="wrap_content" android:text="EditText" android:id="@+id/editText4" android:layout_width="wrap_content"> </EditText> <EditText android:layout_height="wrap_content" android:text="EditText" android:id="@+id/editText5" android:layout_width="wrap_content" android:layout_toRightOf="@id/editText4"> </EditText> <TextView android:text="TextView" android:layout_height="wrap_content" android:layout_alignParentBottom="true" android:layout_width="fill_parent" android:id="@+id/textView3" android:layout_below="@id/editText5" > </TextView> <EditText android:layout_height="wrap_content" android:text="EditText" android:id="@+id/editText5" android:layout_width="fill_parent" android:layout_below="@id/textView3"> </EditText> <TextView android:text="TextView" android:layout_height="wrap_content" android:layout_alignParentBottom="true" android:layout_width="fill_parent" android:layout_below="@id/editText5" android:id="@+id/textView3" > </TextView> <TextView android:text="TextView" android:layout_height="wrap_content" android:layout_alignParentBottom="true" android:layout_width="wrap_content" android:id="@+id/textView3" android:layout_below="@id/textView3" > </TextView> </RelativeLayout> </RelativeLayout> </ScrollView>

  • Appropriate programming design questions.

    - by Edward
    I have a few questions on good programming design. I'm going to first describe the project I'm building so you are better equipped to help me out. I am coding a Remote Assistance Tool similar to TeamViewer, Microsoft Remote Desktop, CrossLoop. It will incorporate concepts like UDP networking (using Lidgren networking library), NAT traversal (since many computers are invisible behind routers nowadays), Mirror Drivers (using DFMirage's Mirror Driver (http://www.demoforge.com/dfmirage.htm) for realtime screen grabbing on the remote computer). That being said, this program has a concept of being a client-server architecture, but I made only one program with both the functionality of client and server. That way, when the user runs my program, they can switch between giving assistance and receiving assistance without having to download a separate client or server module. I have a Windows Form that allows the user to choose between giving assistance and receiving assistance. I have another Windows Form for a file explorer module. I have another Windows Form for a chat module. I have another Windows Form form for a registry editor module. I have another Windows Form for the live control module. So I've got a Form for each module, which raises the first question: 1. Should I process module-specific commands inside the code of the respective Windows Form? Meaning, let's say I get a command with some data that enumerates the remote user's files for a specific directory. Obviously, I would have to update this on the File Explorer Windows Form and add the entries to the ListView. Should I be processing this code inside the Windows Form though? Or should I be handling this in another class (although I have to eventually pass the data to the Form to draw, of course). Or is it like a hybrid in which I process most of the data in another class and pass the final result to the Form to draw? So I've got like 5-6 forms, one for each module. The user starts up my program, enters the remote machine's ID (not IP, ID, because we are registering with an intermediary server to enable NAT traversal), their password, and connects. Now let's suppose the connection is successful. Then the user is presented with a form with all the different modules. So he can open up a File Explorer, or he can mess with the Registry Editor, or he can choose to Chat with his buddy. So now the program is sort of idle, just waiting for the user to do something. If the user opens up Live Control, then the program will be spending most of it's time receiving packets from the remote machine and drawing them to the form to provide a 'live' view. 2. Second design question. A spin off question #1. How would I pass module-specific commands to their respective Windows Forms? What I mean is, I have a class like "NetworkHandler.cs" that checks for messages from the remote machine. NetworkHandler.cs is a static class globally accessible. So let's say I get a command that enumerates the remote user's files for a specific directory. How would I "give" that command to the File Explorer Form. I was thinking of making an OnCommandReceivedEvent inside NetworkHandler, and having each form register to that event. When the NetworkHandler received a command, it would raise the event, all forms would check it to see if it was relevant, and the appropriate form would take action. Is this an appropriate/the best solution available? 3. The networking library I'm using, Lidgren, provides two options for checking networking messages. One can either poll ReadMessage() to return null or a message, or one can use an AutoResetEvent OnMessageReceived (I'm guessing this is like an event). Which one is more appropriate?

  • DDD: Enum like entities

    - by Chris
    Hi all, I have the following DB model: **Person table** ID | Name | StateId ------------------------------ 1 Joe 1 2 Peter 1 3 John 2 **State table** ID | Desc ------------------------------ 1 Working 2 Vacation and domain model would be (simplified): public class Person { public int Id { get; } public string Name { get; set; } public State State { get; set; } } public class State { private int id; public string Name { get; set; } } The state might be used in the domain logic e.g.: if(person.State == State.Working) // some logic So from my understanding, the State acts like a value object which is used for domain logic checks. But it also needs to be present in the DB model to represent a clean ERM. So state might be extended to: public class State { private int id; public string Name { get; set; } public static State New {get {return new State([hardCodedIdHere?], [hardCodeNameHere?]);}} } But using this approach the name of the state would be hardcoded into the domain. Do you know what I mean? Is there a standard approach for such a thing? From my point of view what I am trying to do is using an object (which is persisted from the ERM design perspective) as a sort of value object within my domain. What do you think? Question update: Probably my question wasn't clear enough. What I need to know is, how I would use an entity (like the State example) that is stored in a database within my domain logic. To avoid things like: if(person.State.Id == State.Working.Id) // some logic or if(person.State.Id == WORKING_ID) // some logic

  • Magento Onepage Success Conversion Tracking Design Pattern

    - by user1734954
    My intent is to track conversions through multiple channels by inserting third party javascript (for example google analytics, optimizely, pricegrabber etc.) into the footer of onepage success . I've accomplished this by adding a block to the footer reference inside of the checkout success node within local.xml and everything works appropriately. My questions are more about efficiency and extensibility. It occurred to me that it would be better to combine all of the blocks into a single block reference and then use a various methods acting on a single call to the various related models to provide the data needed for insertion into the javascript for each of the conversion tracking scripts. Some examples of the common data that conversion tracking may rely on(pseudo): Order ID , Order Total, Order.LineItem.Name(foreach) and so on Currently for each of the scripts I've made a call to the appropriate model passing the customers last order id as the load value and the calling a get() assigning the return value to a variable and then iterating through the data to match the values with the expectations of the given third party service. All of the data should be pulled once when checkout is complete each third party services may expect different data in different formats Here is an example of one of the conversion tracking template files which loads at the footer of checkout success. $order = Mage::getModel('sales/order')->loadByIncrementId(Mage::getSingleton('checkout/session')->getLastRealOrderId()); $amount = number_format($order->getGrandTotal(),2); $customer = Mage::helper('customer')->getCustomer()->getData(); ?> <script type="text/javascript"> popup_email = '<?php echo($customer['email']);?>'; popup_order_number = '<?php echo $this->getOrderId() ?>'; </script> <!-- PriceGrabber Merchant Evaluation Code --> <script type="text/javascript" charset="UTF-8" src="https://www.pricegrabber.com/rating_merchrevpopjs.php?retid=<something>"></script> <noscript><a href="http://www.pricegrabber.com/rating_merchrev.php?retid=<something>" target=_blank> <img src="https://images.pricegrabber.com/images/mr_noprize.jpg" border="0" width="272" height="238" alt="Merchant Evaluation"></a></noscript> <!-- End PriceGrabber Code --> Having just a single piece of code like this is not that big of a deal, but we are doing similar things with a number of different third party services. Pricegrabber is one of the simpler examples. A more sophisticated tracking service expects a comma separated list of all of the product names, ids, prices, categories , order id etc. I would like to make it all more manageable so my idea to do the following: combine all of the template files into a single file Develop a helper class or library to deliver the data to the conversion template Goals Include Extensibility Minimal Model Calls Minimal Method Calls The Questions 1. Is a Mage helper the best route to take? 2. Is there any design pattern you may recommend for the "helper" class? 3. Why would this the design pattern you've chosen be best for this instance?

  • Database Design for a double entry accounting system

    - by Khou
    Should journal entries be recorded in a database design? In the real world it makes sense to keep a daily entry book, then later transfer the daily entry book into double entry accounts. but in the computerized version, doing this produces duplicate records and that doesn't quite make sense? ???? What i mean is 1) user enter details , it gets recorded (this would be called the journalbook in real life) 2) the software does all the double entry accounting then references the journalbook and splits up the transaction into the double entry accounting system.

  • REST api design to retrieve summary information

    - by Jacques René Mesrine
    I have a scenario in which I have REST API which manages a Resource which we will call Group. A Group is similar in concept to a discussion forum in Google Groups. Now I have two GET access method which I believe needs separate representations. The 1st GET access method retrieves the minimal amount of information about a Group. Given a *group_id* it should return a minimal amount of information like { group_id: "5t7yu8i9io0op", group_name: "Android Developers", is_moderated: true, number_of_users: 34, new_messages: 5, icon: "http://boo.com/pic.png" } The 2nd GET access method retrives summary information which are more statistical in nature like: { group_id: "5t7yu8i9io0op", top_ranking_users: { [ { user: "george", posts: 789, rank: 1 }, { user: "joel", posts: 560, rank: 2 } ...] }, popular_topics: { [ ... ] } } I want to separate these data access methods and I'm currently planning on this design: GET /group/:group_id/ GET /group/:group_id/stat Only the latter will return the statistical information about the group. What do you think about this ?

  • From a language design perspective, if Javascript objects are simply associative arrays, then why ha

    - by Christopher Altman
    I was reading about objects in O'Reilly Javascript Pocket Reference and the book made the following statement. An object is a compound data type that contains any number of properties. Javascript objects are associative arrays: they associate arbitrary data values with arbitrary names. From a language design perspective, if objects are simply associative arrays, then why have objects? I appreciate the convenience of having objects in the language, but if convenience is the main purpose for adding a data type, then how do you decide what to add and what to not add in a language? A language can quickly become bloated and less valuable if it is weighed down by several overlapping methods and data types (Is this a true statement or am I missing something).

  • robocode engine: how to design (write) the runtime engine -- the robot world

    - by Bob
    IBM has (had) a free learn-Java program called RoboCode, in which custom robots could be written that would then do battle in a 2D space. I would like to write the environment that supports such robots, but don't know what pattern or design to use. Each robot is a thread. Each thread is given a certain (indeterminate) amount of run-time by the JRE. A robot world engine would start by building a list of the players/robots, then enter a loop that allows each player in turn to do whatever it likes: move forward, turn left, fire toward the northwest corner, whatever. Each robot is also informed of events of interest: an enemy or several enemies are within range, it has been hit by a bullet, etc. The combination of handling threads that are also event listeners (are they also producers?) confuses me; it seems that there's more to the game engine. Even some general ideas would help. TIA.

  • Database design for very large amount of data

    - by Hossein
    Hi, I am working on a project, involving large amount of data from the delicious website.The data available is at files are "Date,UserId,Url,Tags" (for each bookmark). I normalized my database to a 3NF, and because of the nature of the queries that we wanted to use In combination I came down to 6 tables....The design looks fine, however, now a large amount of data is in the database, most of the queries needs to "join" at least 2 tables together to get the answer, sometimes 3 or 4. At first, we didn't have any performance issues, because for testing matters we haven't had added too much data in the database. No that we have a lot of data, simply joining extremely large tables does take a lot of time and for our project which has to be real-time is a disaster.I was wondering how big companies solve these issues.Looks like normalizing tables just adds complexity, but how does the big company handle large amounts of data in their databases, don't they do the normalization? thanks

  • Database design in blogging systems

    - by Peter
    As a learning exercise I'm trying to put myself a blogging system. The goal is to code something that will let me create multiple blogs, like blogger.com or wordpress.com, but much simplified. I would like to ask you, what do you think is best database design for this type of script. Is it better to have one big table, containing posts from all blogs of all users (like friendfeed) or would it be better to create separate table for each blog's posts? Big thanks in advance for your help, Peter.

  • OOP Design of items in a Point-of-Sale system

    - by Jonas
    I am implementing a Point-of-Sale system. In the system I represent an Item in three places, and I wounder how I should represent them in OOP. First I have the WarehouseItem, that contains price, purchase price, info about the supplier, suppliers price, info about the product and quantity in warehouse. Then I have CartItem, which contains the same fields as WarehouseItem, but adds NrOfItems and Discount. And finally I have ReceiptItem, thats contains an item where I have stripped of info about the supplier, and only contains the price that was payed. Are there any OOP-recommendations, best-practices or design patterns that I could apply for this? I don't really know if CartItem should contain (wrap) an WarehouseItem, or extend it, or if I just should copy the fields that I need. Maybe I should create an Item-class where I keep all common fields, and then extend it to WarehouseItem, CartItem and ReceiptItem. Sometimes I think that it is good to keep the field of the item and just display the information that is needed.

  • Cost of Design vs Development

    - by Marco
    I usually develop content management solutions in php, I work with designers that create the front end (html & css) and I usually develop the backend (php & mysql) of said cms. I know that the cost of the website may vary depending of the complexity of the html or the backend, but taking as reference a very basic website, what percentage of the cost should go to design and what percentage should go to development. I want to make clear that I as the developer i'm in charge of all the effects and animations of the websites using some of the javascript frameworks, not the designer. I just want to know what´s the fair share for me and for the designer.

  • Database Design for multiple users site

    - by jl
    Hi, I am required to work on a php project that requires the database to cater to multiple users. Generally, the idea is similar to what they have for carbonmade or basecamp, or even wordpress mu. They cater to multiple users, whom are also owners of their accounts. And if they were to cancel/terminate their account, anything on the pages/database would be removed. I am not quite sure how should I design the database? Should it be: separate tables for individual user account separate databases for individual user account or otherwise? Kindly advise me for the best approach to this issue. Thank you very much.

  • Suggestions for Single-Page Web Application Design?

    - by DaveDev
    My view is that unless you need to change the basic structure of the user interface, you should not have to reload the page at all for any user interactions. I'd like to approach my next ASP.NET MVC project with this in mind. Can anyone suggest any principles, patterns or practices* I should consider? Excellent book, btw. Still trying to wrap my head around some of the concepts though. I thought a question like this would help link the theory to a practical design. Thanks

  • FIFA official website design and development

    - by Morron
    Hi, I'm just curious about design and development of official FIFA website. What is the programming language being used to build the site? What is the development methodology they are using? I used Firebug to look around the site.Here's sth I found: HTTP/1.1 200 OK Cache-Control: no-store, no-cache, must-revalidate, private Content-Type: text/html Server: Microsoft-IIS/7.0 x-ua-compatible: IE=EmulateIE7 Vary: Accept-Encoding Content-Length: 8320 Date: Tue, 15 Jun 2010 17:54:19 GMT Connection: keep-alive According to that, I think they use IIS 7 to run the site but I'm not sure what programming language they are using. Any comment is a drop of water in the glass.

    I have a web app that I built for a trucking company that I would like to offer as SaaS. What is the best way to design the database? Should I create a new database for each company?

  • IoC and Design Time

    - by benPearce
    I have a WPF application which I am using to learn MVVM and IoC. The problem is that the Model used by one of the Views expects to pull one of its dependancies in the constructor from an IoC container. When working on this View in the Visual Studio designer it cannot show the design because an exception is being raised in the model. Is there a way around this? Am I pulling my dependancies in the wrong place in code or is there a way I can pass in constructed dependancies, perhaps through Constructor injection. At present the IoC container is setup in code in App.xaml.cs. The IoC container is a roll-your-own taken from this article on MSDN - http://msdn.microsoft.com/en-us/magazine/cc337885.aspx

  • Database design: circular references

    - by SlappyTheFish
    I have three database tables: users emails invitations Emails are linked to users by a user_id field. Invitations are also linked to users by a user_id field Emails can be created without an invitation, but every invitation must have an email. I would like to link the emails and invitations tables so it is possible to find the email for a particular invitation. However this creates a circular reference, both an invitation and an email record hold the id for the same user. Is this bad design and if so, how could I improve it? My feeling is that with use of foreign keys and good business logic, it is fine.

  • 'Design By Contract' in C#

    - by IAmCodeMonkey
    I wanted to try a little design by contract in my latest C# application and wanted to have syntax akin to: public string Foo() { set { Assert.IsNotNull(value); Assert.IsTrue(value.Contains("bar")); _foo = value; } } I know I can get static methods like this from a unit test framework, but I wanted to know if something like this was already built-in to the language or if there was already some kind of framework floating around. I can write my own Assert functions, just don't want to reinvent the wheel.

  • Java Design Questions - Class, Function, Access Modifiers

    - by Ron
    I am newbie to Java. I have some design questions. Say I have a crawler application, that does the following: 1. Crawls a url and gets its content 2. Parses the contents 3. Displays the contents How do you decide between implementing a function or a class? -- Should the parser be a function of the crawler class, or should it be a class in itself, so it can be used by other applications as well? -- If it should be a class, should it be protected or public class? How do you decide between implementing a public or protected class? -- If I had to create a class to generate stats from the parsed contents for eg, should that class be protected (so only the crawler class can access it) or should it be public? Thanks Ron

  • Database with users design

    - by 1110
    I am in database design development phase. Application will work with large number of users (LARGE :)) I designed 80% of database but I have one Users table which is connected to everything else: Users {UserId, FirstName, LastName, Username, Password, PasswordQuestion, PasswordAnswer, Gender, RoleId, LastLoginDate etc etc} I saw asp.net membership database structure where Users and Membership are two tables. My questions are: Should I use one users table with all users data in it or more tables? If answer is 'more tables', what tables to use? Any advice on how to structure relation between those tables? This is sample relation that I have, and trying to improve. I don't understand why user and userChild are separated tables?

  • Best Design pattern for social media file transfer

    - by Onema
    Our system would like our clients to link their accounts with different social media sites like youtube, vimeo, facebook, myspace and so on. One of the benefits we would like to give to the user is to transfer, update and delete files they have uploaded to our sites and transfer them to the social media sites mentioned above. this files could be videos, images or audio. We started thinking about using a strategy pattern, as all of these sites share a common process ( authentication, connection, use the API to transfer/edit/delete the file ), but we soon realized that it may not work as me may want to use some of the extended functionality that is specific to each service (eg: associate a youtube video with a channel, or upload images to a specific album on facebook, and much, much more...) My question is, what would be the best Structural Design Patter to use for this scenario?
