  • How do I make Views fill the full width of their parent in my Android app?

    - by Omega
    I have the following layout defined for one of my Activities: <?xml version="1.0" encoding="utf-8"?> <TableLayout android:id="@+id/TableLayout01" android:layout_width="fill_parent" android:layout_height="fill_parent" xmlns:android="http://schemas.android.com/apk/res/android"> <TableRow android:id="@+id/TableRow01" android:layout_height="wrap_content" android:layout_width="fill_parent"> <EditText android:text="Resource Name" android:id="@+id/ResourceName" android:lines="1" android:isScrollContainer="false"></EditText> </TableRow> <TableRow android:id="@+id/TableRow02" android:layout_height="wrap_content" android:layout_width="fill_parent"> <Button android:id="@+id/Tile" android:text="Tile"></Button> </TableRow> </TableLayout> The layout renders almost correctly, the only problem is that my text box and my button aren't occupying the full width of their respective rows. I've tried specifying fill_parent for the layout width properties, but to no avail, they still only occupy roughly half of the screen. Documentation overall for Android so far has been great, but there are a few scenarios like this one where I hit an invisible wall! Thanks for all the help!

  • Authentication problem with Wufoo

    - by fudgey
    I set up a Wufoo form with admin only portions that will only show up if I am logged in. I read through the Wufoo API documentation and I can get the authenication to work, but when I try to access the form after I authenticate, it says I need to authenticate. This is what I have so far (subdomain, api key & form id changed) <?php error_reporting(E_ALL); ini_set('display_errors', 1); $curl1 = curl_init('http://fishbowl.wufoo.com/api/v3/users.xml'); curl_setopt($curl1, CURLOPT_RETURNTRANSFER, 1); curl_setopt($curl1, CURLOPT_USERPWD, 'AOI6-LFKL-VM1Q-IEX9:footastic'); curl_setopt($curl1, CURLOPT_HTTPAUTH, CURLAUTH_ANY); curl_setopt($curl1, CURLOPT_SSL_VERIFYPEER, false); curl_setopt($curl1, CURLOPT_FOLLOWLOCATION, false); curl_setopt($curl1, CURLOPT_USERAGENT, 'Wufoo Sample Code'); $response = curl_exec($curl1); $resultStatus = curl_getinfo($curl1); if($resultStatus['http_code'] == 200) { echo 'success!<br>'; } else { echo 'Call Failed '.print_r($resultStatus); } $curl2 = curl_init("http://fishbowl.wufoo.com/api/v3/forms/w7x1p5/entries.json"); curl_setopt($curl2, CURLOPT_HEADER, 0); curl_setopt($curl2, CURLOPT_RETURNTRANSFER, 1); $response = curl_exec($curl2); curl_close ($curl2); echo $response; curl_close($curl1); ?> It doesn't matter if I close $curl1 before or after I call $curl2, I get the same message on my screen: success! You must authenticate to get at the goodies. and I know the api, subdomain and form id are all correct. And one last bonus question... can I do all of this using Ajax instead? - the page I will be displaying the form on will already be limited to admin access, so exposing the API shouldn't matter.

  • The RSA key container could not be opened

    - by TenaciousImpy
    Hi, I've been developing an ASP.NET site on an older machine running XP home. I recently got a new Win 7 PC and moved all my project files across. When I try and run the project, I get this error message: "Failed to decrypt using provider 'MyRsaProtectedConfigurationProvider'. Error message from the provider: The RSA key container could not be opened." I realised that I encrypted parts of my web.config file using a RSA encryption. This is where the problem now lies. I'm not sure how to get that key working again so that I can use it on my new machine. I exported the key from the older machine and imported it using: aspnet_regiis -pi "RSAProviderName" "C:\RSA_configkey.xml" This was imported successfully. I then ran the project, but the same error message came up. I figured it might be a permission thing, so I ran: aspnet_regiis -pa "RSAProviderName" "\Desktop" -full This was also successful, but I still get the error. From reading around, I've seen people use "ASPNET" instead of "\Desktop" (Desktop is my machine name). However, when I try and use "ASPNET", I get: No mapping between account name and security IDs was done. <Exception from HRESULT = 0x80070534 I can't work on the project until this is fixed, so any help is much appreciated. Thanks!

  • Android : Customizing tabs on state : How do I make a selector a drawable

    - by Chrispix
    I know how to put the icon on each tab, that is no problem. I also ran across this : Stack Overflow thread on pretty much same thing I followed one of the links from that question, and found this Pretty much, it said use a selector defined in the xml, sure, did that. But there is no id associated w/ it so I am not sure how to get the selector function as a drawable so I can use it as the icon for the tabs. Maybe I am going about this the wrong way.. But this is what I have, and obviously missing something. <selector android:id="@+id/myselector" xmlns:android="http://schemas.android.com/apk/res/android"> <!-- Non focused states --> <item android:state_focused="false" android:state_selected="false" android:state_pressed="false" android:drawable="@drawable/darklogo" /> <item android:state_focused="false" android:state_selected="true" android:state_pressed="false" android:drawable="@drawable/lightlogo" /> <!-- Focused states --> <item android:state_focused="true" android:state_selected="false" android:state_pressed="false" android:drawable="@drawable/lightlogo" /> <item android:state_focused="true" android:state_selected="true" android:state_pressed="false" android:drawable="@drawable/lightlogo" /> <!-- Pressed --> <item android:state_pressed="true" android:drawable="@drawable/lightlogo" /> </selector> In my code, an example tab is generated using : host.addTab(host.newTabSpec("three") .setIndicator("map",drawables) .setContent(new Intent(this, Map.class))); Right now drawables is just a reference to an drawable image resource. How do I make the selector a drawable? * This is my question *

  • SSL HandShakeException: No_Certificate. Using IBM's J9 JVM and Apache Tomcat

    - by DaveJohnston
    I am developing a mobile application that is to run on a Windows Mobile PDA. The application is written in Java and to run it we are using the J9 JVM from IBM. The application communicates with an Apache Tomcat server over HTTP and we are trying to set it up now to use SSL. I have generated public/private keys for both the client and the server, exported their self signed certificates and imported them into the respective keystores. Initially I tried to just get it working using only server side authentication and that was successful. But I am now trying to get mutual authentication by setting clientAuth="true" in the server.xml file in the apache conf directory. I have enabled the SSL logging on the server and when the client connects the server reports an SSLProtocolException: handshake alert: no_certificate. The client logs also show an exception: javax.net.ssl.SSLHandshakeException: unexpected_message at com.ibm.j9.jsse.SSLSocketImpl.completeHandshake(Unknown Source) at com.ibm.j9.jsse.SSLSocketImpl.startHandshake(Unknown Source) at com.ibm.oti.net.www.protocol.https.HttpsURLConnection.openSocket(Unknown Source) at com.ibm.oti.net.www.protocol.https.HttpsURLConnection.connect(Unknown Source) at com.ibm.oti.net.www.protocol.https.HttpsURLConnection.sendRequest(Unknown Source) at com.ibm.oti.net.www.protocol.https.HttpsURLConnection.doRequest(Unknown Source) at com.ibm.oti.net.www.protocol.https.HttpsURLConnection.getInputStream(Unknown Source) The client keystore and truststore is configured by setting the following System Properties: javax.net.ssl.trustStore javax.net.ssl.trustStorePassword javax.net.ssl.keyStore javax.net.ssl.keyStorePassword Does anyone have any ideas how I can set up client authentication on the J9 JVM?

  • How to import data to SAP

    - by Mehmet AVSAR
    Hi, As a complete stranger in town of SAP, I want to transfer my own application's (mobile salesforce automation) data to SAP. My application has records of customers, stocks, inventory, invoices (and waybills), cheques, payments, collections, stock transfer data etc. I have an additional database which holds matchings of records. ie. A customer with ID 345 in my application has key 120-035-0223 in SAP. Every record, for sure, has to know it's counterpart, including parameters. After searching Google and SAP help site for a day, I covered that it's going to be a bit more pain than I expected. Especially SAP site does not give even a clue on it. Say I couldn't find. We transferred our data to some other ERP systems, some of which wanted XML files, some other exposed their APIs. My point is, is Sql Server's SSIS an option for me? I hope it is, so I can fight on my own territory. Since client requests would vary a lot, I count flexibility as most important criteria. Also, I want to transfer as much data as I could. Any help is appreciated. Regards,

  • Amazon S3 and swfaddress

    - by justinbach
    I recently migrated a large AS3 site (lots of swfs, lots of flvs) to Amazon S3. Pretty much everything but HTML and JS files is being stored/served from Amazon, and it's working well. The only problem I'm having is that I built the site using SWFaddress (actually, via the Gaia framework which uses SWFaddress), and for some reason, SWFaddress is no longer updating the address bar correctly as users navigate from page to page. In other words, the URL persistently remains http://www.mysite.com, not http://www.mysite.com/#/section as would be the case were SWFaddress functioning correctly (and as it was functioning prior to the migration). Stranger yet, if I go to (e.g.) http://www.mysite.com/#/section directly, the deeplinking functions as you'd expect--I arrive directly at the correct section. However, navigating away from that section doesn't have any effect on the address bar, despite the fact that it should be dynamically updated. I've got a crossdomain.xml file set up on the site that allows access from all domains, so that's not the issue, and I don't know what else might be. Any ideas would be greatly appreciated! P.S. I integrated S3 by putting pretty much the entire site in an S3 bucket and then just changing the initial swfobject embed to point to the S3 instance of main.swf, passing in the S3 path as the "base" param to the embedded swf so that all dynamically loaded assets and swfs would also be sourced from s3. Dunno if that's related to the troubles I'm having.

  • Ruby or Rails reporting tools?

    - by Anushank
    I am looking for a report generation tool in ruby or rails which allows the user to define a template, then fetch data into the created template. I have been looking through "The Ruby Box: reporting section." There are two reporting tools I have looked at: Thin Reports: It is really good. You can create your own report template with the template editor. Then you can produce PDF reports using thinreports gems. ODF Report: You can create a template ODF file using Open Office and MS Word, and you can use that template to generate the report. Both of these solutions lack the ability to draw charts. Does anyone know of similar reporting tools that can draw charts within a given report? I have tried the RTF Ruby Library. It works, but shares the limitation that it cannot draw charts and graphs. The minimum requirements are: Able to create customizable templates. (e.g. design layout, set font size, color, embed images etc.) Able to draw tables and charts. Template could be in Docx or excel or xml or any other common file format. Report output report must be in Docx or RTF format. Thanks

  • Why can I run JUnit tests for my Spring project, but not a main method?

    - by FarmBoy
    I am using JDBC to connect to MySQL for a small application. In order to test without altering the real database, I'm using HSQL in memory for JUnit tests. I'm using Spring for DI and DAOs. Here is how I'm configuring my HSQL DataSource <bean id="mockDataSource" class="org.springframework.jdbc.datasource.SingleConnectionDataSource"> <property name="driverClassName" value="org.hsqldb.jdbcDriver"/> <property name="url" value="jdbc:hsqldb:mem:mockSeo"/> <property name="username" value="sa"/> </bean> This works fine for my JUnit tests which use the mock DB. But when I try to run a main method, I find the following error: Error creating bean with name 'mockDataSource' defined in class path resource [beans.xml]: Error setting property values; nested exception is org.springframework.beans.PropertyBatchUpdateException; nested PropertyAccessExceptions (1) are: PropertyAccessException 1: org.springframework.beans.MethodInvocationException: Property 'driverClassName' threw exception; nested exception is java.lang.IllegalStateException: Could not load JDBC driver class [org.hsqldb.jdbcDriver] I'm running from Eclipse, and I'm using the Maven plugin. Is there a reason why this would work as a Test, but not as a main()? I know that the main method itself is not the problem, because it works if I remove all references to the HSQL DataSource from my Spring Configuration file.

  • Uploading to TwitVid using x_verify_credentials_authorization

    - by deepa
    Hi, I am developing an iPhone application that uploads videos to TwitVid using the library TwitVid-iPhone-OAuth3. I have selected this library since Twitter is shifting to OAuth mechanism of authentication. 1) Does this new library allows to upload without user-name and password parameters? 2) I am using the following steps for uploading videos (assumed that new library allows to upload without user-name and password parameters). But, I am getting the error 'Incorrect Signature'. I am not able to identify the mistake that I am doing here. Could you please help me out to solve this problem. Authenticate the app using OAuth (MGTwitterEngine etc) which redirects the user to the web-page asking for log-in and app authentication. If the user authenticates the app, access token will obtained as final step. Upload the video to TwitVid using the following code snippet: OAuth *authorizer = [[OAuth alloc] initWithConsumerKey: @"my_consumer_key" andConsumerSecret: @"my_consumer_secret"]; authorizer.oauth_token = //The key-part of the access token obtained in step 2 authorizer.oauth_token_secret = //The secret-part of the access token obtained in step 2 authorizer.oauth_token_authorized = YES; //Since authenticated in steps 1 and 2 NSString *authHeader = [authorizer oAuthHeaderForMethod: @"POST" andUrl: @"https://api.twitter.com/1/account/verify_credentials.xml" andParams: nil]; twitVid = [[TwitVid alloc] init]; [mTwitVid setDelegate: self]; [mTwitVid authenticateWithXVerifyCredentialsAuthorization: authHeader xAuthServiceProvider: nil]; Thanks and Regards, Deepa

  • Question on MacPorts comment: "manually remove the catalog entry for this port when you uninstall it

    I was recently installing Inkscape with MacPorts through a Mac OSX Leopard Terminal using "sudo port install inkscape" And during the search-and-download for dependencies, many of these type of comments were printed: ###################################################################### # As MacPorts does not currently have a post-deactivate hook, # you will need to ensure that you manually remove the catalog # entry for this port when you uninstall it. To do so, run # "xmlcatmgr remove nextCatalog /opt/local/share/xsl/docbook-xsl/catalog.xml". ###################################################################### Can anyone tell me what this message means? I do not understand what "it" refers to in the phrase 'ensure that you manually remove the catalog entry for this port when you uninstall it'. Does 'it' refer to a 'this port'? How is a port uninstalled? Mostly: When will I have to manually remove the catalog entry using the provided command? Also, what is a catalog entry? is that what appears when I type "sudo port search inkscape" ? I am kind of a MacPorts install n00b. Thanks very much for your time.

  • Add Zend_Navigation to the View with old legacy bootstrap

    - by Grant Collins
    Hi, I've been struggling with Zend_Navigation all weekend, and now I have another problem, which I believe has been the cause of a lot of my issues. I am trying to add Zend_Navigation to a legacy 1.7.6 Zend Framework application, i've updated the Zend Library to 1.9.0 and updated the bootstrap to allow this library update. The problem is that I don't know how, and the examples show the new bootstrap method of how to add the Navigation object to the view, I've tried this: //initialise the application layouts with the MVC helpers $layout = Zend_Layout::startMvc(array('layoutPath' => '../application/layouts')); $view = $layout->getView(); $configNav = new Zend_Config_Xml('../application/config/navigation.xml', 'navigation'); $navigation = new Zend_Navigation($configNav); $view->navigation($navigation); $viewRenderer = new Zend_Controller_Action_Helper_ViewRenderer(); $viewRenderer->setView($view); This seems to run through fine, but when I go to use the breadcrumb view helper in my layout, it errors with: Strict Standards: Creating default object from empty value in C:\www\moobia\development\website\application\modules\employers\controllers\IndexController.php on line 27 This is caused by the following code in the init() function of my controller. $uri = $this->_request->getPathInfo(); $activeNav = $this->view->navigation()->findByUri($uri); <- this is null when called $activeNav->active = true; I believe it's because the Zend_Navigation object is not in the view. I would look at migrating the bootstrap to the current method, but at present I am running out of time for a release. Thanks, Grant

  • java.net.SocketException: Software caused connection abort: recv failed; Causes and cures?

    - by IVR Avenger
    Hi, all. I've got an application running on Apache Tomcat 5.5 on a Win2k3 VM. The application serves up XML to be consumed by some telephony appliances as part of our IVR infrastructure. The application, in turn, receives its information from a handful of SOAP services. This morning, the SOAP services were timing out intermittently, causing all sorts of Exceptions. Once these stopped, I noticed that our application was still performing very slowly, in that it took it a long time to render and deliver pages. This sluggishness was noticed both on the appliances that consume the Tomcat output, and from a simple test of requesting some static documents from my web browser. Restarting Tomcat immediately resolved the issue. Cracking open the localhost log, I see a ton of these errors, right up until I restarted Tomcat: WARNING: Exception thrown whilst processing POSTed parameters java.net.SocketException: Software caused connection abort: recv failed After a big of Googling, my working theory is that the SOAP issue caused my users to get errors, which caused them to make more requests, which put an increased load on the application. This caused it to run out of available sockets to handle incoming requests. So, here's my quandary: 1. Is this a valid hypothesis, or am I just in over my head with HTTP and Tomcat? 2. If this is a valid hypothesis, is there a way to increase the size of the "socket queue", so that this doesn't happen in the future? Thanks! IVR Avenger

  • Android: Can not send http post

    Hi all, I've been banging my head trying to figure out how to send a post method in Android. This is how my code look like: public class HomeActivity extends Activity implements OnClickListener { private TextView textView; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); textView = (TextView) findViewById(R.id.text); Button button = (Button)findViewById(R.id.button); button.setOnClickListener(this); } @Override public void onClick(View view) { HttpPost httpMethod = new HttpPost("http://www.example.com/"); httpMethod.addHeader("Accept", "text/html"); httpMethod.addHeader("Content-Type", "application/xml"); AndroidHttpClient client = AndroidHttpClient.newInstance("Android"); String result = null; try { HttpResponse response = client.execute(httpMethod); textView.setText(response.toString()); HttpEntity entity = response.getEntity(); Log.i(HomeActivity.class.toString(), result); textView.setText("Invoked webservice"); } catch (IOException e) { e.printStackTrace(); Log.e(HomeActivity.class.toString(), e.getMessage()); textView.setText("Something wrong:" + e.getMessage()); } } } What am I doing wrong here? Is there anything that I may need to configure from the Android emulator to get this working? Thank you for your help.

  • Apache Tomcat under Windows: Changing webapps default directory

    - by Maerch
    I am deploying my Java application with Ant. Unfortunately my test deployment on the local machine doesn't work because of Vista. The Program Files directionaries are protected and i don't want to start Ant or Eclipse as an Admin. So i had the idea to move my webapps folder to a workspace subfolder, so i can use relative paths in Ant as well. The solutions seems to be to modify the Host element in the server.xml. With Linux it isn't such a deal: <Host name="localhost" appBase="/path/to/webapps" unpackWARs="true" autoDeploy="true" xmlValidation="false" xmlNamespaceAware="false"> But with Windows i don't get it right. I tried every possible combinations i could imagine, like: C://Users//maerch//Workspaces//Tomcat6.0_webapps C:/Users/maerch/Workspaces/Tomcat6.0_webapps C:\Users\maerch\Workspaces\Tomcat6.0_webapps C:\\Users\\maerch\\Workspaces\\Tomcat6.0_webapps C://Users//maerch//Workspaces//Tomcat6.0_webapps\\ C:/Users/maerch/Workspaces/Tomcat6.0_webapps/ C:\Users\maerch\Workspaces\Tomcat6.0_webapps\ C:\\Users\\maerch\\Workspaces\\Tomcat6.0_webapps\\ The path is also correct, but it doesn't work. There are also no error messages in the log files neither the browser shows a 404 message or anything else. Just a white page without title and so on. Can anyone help?

  • Get "term is undefined” error when trying to assign arrayList to List component dataSource

    - by user1814467
    I'm creating an online game where people log in and then have the list of current players displayed. When the user enters a "room" it dispatches an SFSEvent which includes a Room object with the list of users as User objects in that room. As that event's callback function, I get the list of current users which is an Array, switch the View Stack child index, and then I wrap the user list array in an ArrayList before I assign it to the MXML Spark List component's dataSource. Here's my code: My Actionscript Code Section (PreGame.as): private function onRoomJoin(event:SFSEvent):void { const room:Room = this._sfs.getRoomByName(PREGAME_ROOM); this.selectedChild = waitingRoom; /** I know I should be using event listeners * but this is a temporary fix, otherwise * I keep getting null object errors * do to the li_users list not being * created in time for the dataProvider assignment **/ setTimeout(function ():void { const userList:ArrayList = new ArrayList(room.userList); this.li_users.dataProvider = userList; // This is where the error gets thrown },1000); } My MXML Code: <?xml version="1.0" encoding="utf-8"?> <mx:ViewStack xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark" xmlns:mx="library://ns.adobe.com/flex/mx" initialize="preGame_initializeHandler(event)" > <fx:Script source="PreGame.as"/> <s:NavigatorContent id="nc_loginScreen"> /** Login Screen Code **/ </s:NavigatorContent> /** Start of Waiting Room code **/ <s:NavigatorContent id="waitingRoom"> <s:Panel id="pn_users" width="400" height="400" title="Users"> /** This is the List in question **/ <s:List id="li_users" width="100%" height="100%"/> </s:Panel> </s:NavigatorContent> </mx:ViewStack> However, I keep getting this error: TypeError: Error #1010: A term is undefined and has no properties Any ideas what I'm doing wrong?

  • Why do Unicode characters show up properly in database, but as ? when printed in Java via Hibernate?

    - by lupefiasco
    I'm writing a webapp, and interfacing with MySQL using Hibernate 3.5. Using "?????? ?????????" as my test string, I can input the string and see that it is properly persisted into the database. However, when I later pull the value out of the database and print to the console as a String, I see "?????? ?????????". If I use new OutputStreamWriter(System.out,"UTF-8"); then I get "„Éá„Çp„ÇØ„Éà„ÉÉ„Éó ·Éò·Éú·Éí·Éö·Éò·É°·É£·É†·Éò"". Why don't I see the original string? These are my hibernate.cfg.xml settings: <property name="hibernate.connection.useUnicode"> true </property> <property name="hibernate.connection.characterEncoding"> UTF-8 </property> <property name="hibernate.connection.charSet"> UTF-8 </property> and this is my database connection string: hibernate.connection.url = jdbc:mysql://localhost/mydatabase?autoReconnect=true&amp;useUnicode=true&amp;characterEncoding=UTF-8

  • Android accessibility focus - clicking a view changes focus to previous view

    - by benkdev
    I'm using android TalkBack to test my application for accessibility use. When I swipe to select a view and double tap, the focus returns the the view above it. Usually when swiping to a view and double clicking it, onClick is called. What am I doing wrong? <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" android:background="@color/all_white" > <ImageView android:layout_width="wrap_content" android:layout_height="wrap_content" android:src="@drawable/header" android:scaleType="center" /> <ImageView android:layout_width="wrap_content" android:layout_height="wrap_content" android:src="@drawable/green_bar" android:scaleType="center" /> <ImageView android:layout_width="wrap_content" android:layout_height="wrap_content" android:src="@drawable/blue_bar" android:scaleType="center" /> <EditText android:id="@+id/username" android:layout_width="325dp" android:layout_height="wrap_content" android:hint="@string/username" android:focusable="true" android:nextFocusDown="@id/password" /> <EditText android:id="@+id/password" android:inputType="textPassword" android:layout_width="325dp" android:layout_height="wrap_content" android:hint="@string/password" android:focusable="true" android:nextFocusUp="@id/username" android:nextFocusDown="@id/login" /> <Button android:id="@+id/login" android:onClick="doLogin" android:focusable="true" android:layout_width="325dp" android:layout_height="wrap_content" android:text="@string/login" android:nextFocusUp="@id/password" android:nextFocusDown="@id/create_trial_account" /> <Button android:id="@+id/create_trial_account" android:layout_width="100dip" android:layout_height="wrap_content" android:text="@string/new_user" android:onClick="createAccount" android:focusable="true" android:nextFocusUp="@id/login" /> <TextView android:id="@+id/copyright" android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="@string/copyright" /> <TextView android:id="@+id/buildNumber" android:layout_width="fill_parent" android:layout_height="wrap_content" /> </LinearLayout>

  • Correctly use dependency injection

    - by Rune
    Me and two other colleagues are trying to understand how to best design a program. For example, I have an interface ISoda and multiple classes that implement that interface like Coke, Pepsi, DrPepper, etc.... My colleague is saying that it's best to put these items into a database like a key/value pair. For example: Key | Name -------------------------------------- Coke | my.namespace.Coke, MyAssembly Pepsi | my.namespace.Pepsi, MyAssembly DrPepper | my.namespace.DrPepper, MyAssembly ... then have XML configuration files that map the input to the correct key, query the database for the key, then create the object. I don't have any specific reasons, but I just feel that this is a bad design, but I don't know what to say or how to correctly argue against it. My second colleague is suggesting that we micro-manage each of these classes. So basically the input would go through a switch statement, something similiar to this: ISoda soda; switch (input) { case "Coke": soda = new Coke(); break; case "Pepsi": soda = new Pepsi(); break; case "DrPepper": soda = new DrPepper(); break; } This seems a little better to me, but I still think there is a better way to do it. I've been reading up on IoC containers the last few days and it seems like a good solution. However, I'm still very new to dependency injection and IoC containers, so I don't know how to correctly argue for it. Or maybe I'm the wrong one and there's a better way to do it? If so, can someone suggest a better method? What kind of arguments can I bring to the table to convince my colleagues to try another method? What are the pros/cons? Why should we do it one way? Unfortunately, my colleagues are very resistant to change so I'm trying to figure out how I can convince them.

  • What AOP tools exist for doing aspect-oriented programming at the assembly language level against x8

    - by JohnnySoftware
    Looking for a tool I can use to do aspect-oriented programming at the assembly language level. For experimentation purposes, I would like the code weaver to operate native application level executable and dynamic link libraries. I have already done object-oriented AOP. I know assembly language for x86 and so forth. I would like to be able to do logging and other sorts of things using the familiar before/after/around constructs. I would like to be able to specify certain instructions or sequences/patterns of consecutive instructions as what to do a pointcut on since assembly/machine language is not exactly the most semantically rich computer language on the planet. If debugger and linker symbols are available, naturally, I would like to be able to use them to identify subroutines' entry points , branch/call/jump target addresses, symbolic data addresses, etc. I would like the ability to send notifications out to other diagnostic tools. Thus, support for sending data through connection-oriented sockets and datagrams is highly desirable. So is normal logging to files, UI, etc. This can be done using the action part of an aspect to make a function call, but then there are portability issues so the tool needs to support a flexible, well-abstracted logging/notifying mechanism with a clean, simple yet flexible. The goal is rapid-QA. The idea is to be able to share aspect source code braodly within communties as well as publicly. So, there needs to be a declarative security policy file that users can share. This insures that nothing untoward that is hidden directly or indirectly in an aspect source file slips by the execution manager. The policy file format needs to be simple to read, write, modify, understand, type-in, edit, and generate. Sort of like Java .policy files. Think the exact opposite of anything resembling XML Schema files and you get the idea. Is there such a tool in existence already?

  • NSKeyedArchiver on NSArray has large size overhead

    - by redguy
    I'm using NSKeyedArchiver in Mac OS X program which generates data for iPhone application. I found out that by default, resulting archives are much bigger than I expected. Example: NSMutableArray * ar = [NSMutableArray arrayWithCapacity:10]; for (int i = 0; i < 100000; i++) { NSString * s = [NSString stringWithFormat:@"item%06d", i]; [ar addObject:s]; } [NSKeyedArchiver archiveRootObject:ar toFile: @"NSKeyedArchiver.test"]; This stores 10 * 100000 = 1M bytes of useful data, yet the size of the resulting file is almost three megabytes. The overhead seems to be growing with number of items in the array. In this case, for 1000 items, the file was about 22k. "file" reports that it is a "Apple binary property list" (not the XML format). Is there an simple way to prevent this huge overhead? I wanted to use the NSKeyedArchiver for the simplicity it provides. I can write data to my own, non-generic, binary format, but that's not very elegant. Also, aggregating the data into large chunks and feeding these to the NSKeyedArchiver should work, but again, that kinda beats the point of using simple&easy&ready to use archiver. Am I missing some method call or usage pattern that would reduce this overhead?

  • How does Subsonic handle connections?

    - by Quintin Par
    In Nhibernate you start a session by creating it during a BeginRequest and close at EndRequest public class Global: System.Web.HttpApplication { public static ISessionFactory SessionFactory = CreateSessionFactory(); protected static ISessionFactory CreateSessionFactory() { return new Configuration() .Configure(Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "hibernate.cfg.xml")) .BuildSessionFactory(); } public static ISession CurrentSession { get{ return (ISession)HttpContext.Current.Items["current.session"]; } set { HttpContext.Current.Items["current.session"] = value; } } protected void Global() { BeginRequest += delegate { CurrentSession = SessionFactory.OpenSession(); }; EndRequest += delegate { if(CurrentSession != null) CurrentSession.Dispose(); }; } } What’s the equivalent in Subsonic? The way I understand, Nhibernate will close all the connections at endrequest. Reason: While trouble shooting some legacy code in a Subsonic project I get a lot of MySQL timeouts,suggesting that the code is not closing the connections MySql.Data.MySqlClient.MySqlException: error connecting: Timeout expired. The timeout period elapsed prior to obtaining a connection from the pool. This may have occurred because all pooled connections were in use and max pool size was reached. Generated: Tue, 11 Aug 2009 05:26:05 GMT System.Web.HttpUnhandledException: Exception of type 'System.Web.HttpUnhandledException' was thrown. --- MySql.Data.MySqlClient.MySqlException: error connecting: Timeout expired.
