  • Consuming ASMX and WCF Services using jQuery

    - by bipinjoshi
    In the previous part I demonstrated how jQuery animations can add some jazz to your web forms. Now let's see one of the most important feature of jQuery that you will probably use in all data driven websites - accessing server data. In the previous articles you used jQuery methods such as $.get() to make a GET request to the server. More powerful feature, however, is to make AJAX calls to ASP.NET Web Services, Page Methods and WCF services. The $.ajax() method of jQuery allows you to access these services. In fact $.get() method you used earlier internally makes use of $.ajax() method but restricts itself only to GET requests. The $.ajax() method provides more control on how the services are called.http://www.bipinjoshi.net/articles/479571df-7786-4c50-8db6-a798f195471a.aspx

  • Using both .co.uk and .com domain

    - by Mantorok
    We presently have a .co.uk domain that has been live now for around 9-10 months, recently the .com version of this domain has become available and we've purchased based on reading that suggests you should try and go for .com where possible. My issue now is, what should I do with the .com? Should I use this in favour of the .co.uk or use both? I'm concerned that rankings might be affected if I completely replace the .co.uk with the .com. Any suggestions?

  • Using DesktopCouch without Ubuntu One?

    - by burli
    I want to know if it is possible to use DesktopCouch without UbuntuOne, but with a local CouchDB Server. I found a pairing Tool, but this crashes, when I try to pair two computer. I can find the local Desktop Couches with the Avahi Zeroconf Browser and it should be possible to find them with Python and start a replication To make a long story short: I want to sync DesktopCouch Databases in my local network without Ubuntu One. Is that possible?

  • Instruct Ubuntu to boot TORAM from flash drive using unetbootin

    - by Goyuix
    I have used UNetbootin to create an installable / live bootable flash drive from Ubuntu 12.04. However that didn't preserve the normal Ubuntu boot menu which allows to me to enter advanced options. It has a custom menu that I can pick from predefined choices like "Install Ubuntu" and "Try Ubuntu without installing". What I would like is to be able to boot from the USB flash drive, but then be able to remove it from the computer once the desktop has loaded. The laptop I would like to use this on does not have a CD/DVD drive. What do I need to modify on the flash drive to add an option to "Try Ubuntu (RAM)" that passes the TORAM=yes parameter to the initrd options? Are their other things I need to touch/change as well? Bonus: I would guess the answer would also allow for other options like acpi=off as well, but if it is different I would appreciate having that answer too.

  • Problems using custom keyboard layout / symbols file

    - by January
    I have a custom xkb symbols file which looks as follows: // modify the basic German layout to have polish characters default partial alphanumeric_keys xkb_symbols "basic" { include "de(basic)" name[Group1]="Germany - with polish characters"; key <AD03> { [ e, E, eogonek, Eogonek ] }; key <AD09> { [ o, O, oacute, Oacute ] }; key <AC01> { [ a, A, aogonek, Aogonek ] }; key <AC02> { [ s, S, sacute, Sacute ] }; key <AD06> { [ z, Z, zabovedot, Zabovedot ] }; key <AB02> { [ x, X, zacute, Zacute ] }; key <AB03> { [ c, C, cacute, Cacute ] }; key <AB06> { [ n, N, nacute, Nacute ] }; }; The name of the file is depl. I copy the file to /usr/share/X11/xkb/symbols and it works with setxkbmap depl. However, I also tried to add the respective menu entries in the "Text Entry" customization. I have modified the file /usr/share/X11/xkb/rules/evdev.xml and added the following section: <layout> <configItem> <name>depl</name> <shortDescription>depl</shortDescription> <description>German (with Polish characters)</description> <languageList> <iso639Id>ger</iso639Id> </languageList> </configItem> </layout> I have then reconfigured the xkb data with sudo dpkg-reconfigure xkb-data. It works in as much as that the new layout appears as a viable option in the Text Entry dialog, it can be added to the list of dialogs and is visible in the application indicator: However, it does not work, the new symbols are not loaded. No errors are reported in /var/log/Xorg.0.log.

  • Problem with deleting table rows using ctrl+a for row selection

    - by Frank Nimphius
    Normal 0 false false false EN-US X-NONE X-NONE /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-fareast-font-family:"Times New Roman"; mso-fareast-theme-font:minor-fareast; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi;} The following code is commonly shown and documented for how to access the row key of selected table rows in an ADF Faces table configured for multi row selection. public void onRemoveSelectedTableRows(ActionEvent actionEvent) {    RichTable richTable = … get access to your table instance …    CollectionModel cm =(CollectionModel)richTable.getValue();    RowKeySet rowKeySet = (RowKeySet)richTable.getSelectedRowKeys();             for (Object key : rowKeySet) {       richTable.setRowKey(key);       JUCtrlHierNodeBinding rowData = (JUCtrlHierNodeBinding)cm.getRowData();       // do something with rowData e.g.update, print, copy   }    //optional, if you changed data, refresh the table         AdfFacesContext adfFacesContext = AdfFacesContext.getCurrentInstance(); adfFacesContext.addPartialTarget(richTable);   return null; } The code shown above works for 99.5 % of all use cases that deal with multi row selection enabled ADF Faces tables, except for when users use the ctrl+a key to mark all rows for delete. Just to make sure I am clear: if you use ctrl+a to mark rows to perform any other operation on them – like bulk updating all rows for a specific attribute – then this works with the code shown above. Even for bulk row delete, any other mean of row selection (shift+click and multiple ctrl+click) works like a charm and the rows are deleted. So apparently it is the use of ctrl+a that causes the problem when deleting multiple rows of an ADF Faces table. To implement code that works for all table selection use cases, including the one to delete all table rows in one go, you use the code shown below. public void onRemoveSelectedTableRows(ActionEvent actionEvent) {   RichTable richTable = … get access to your table instance …   CollectionModel cm = (CollectionModel)richTable.getValue();   RowKeySet rowKeySet = (RowKeySet)richTable.getSelectedRowKeys();   Object[] rowKeySetArray = rowKeySet.toArray();      for (Object key : rowKeySetArray){               richTable.setRowKey(key);     JUCtrlHierNodeBinding rowData = (JUCtrlHierNodeBinding)cm.getRowData();                              rowData.getRow().remove();   }   AdfFacesContext adfFacesContext = AdfFacesContext.getCurrentInstance();          adfFacesContext.addPartialTarget(richTable); }

  • Using SOUNDEX and DIFFERENCE to Standardize Data in SQL Server

    My client wants to standardize address information for existing and future addresses collected for their customers, particularly the street suffixes. The application used to enter and collect address information has the street suffix separated from the address field, but it is a textbox instead of a drop down list therefore things are not standardized. I know there are some options out there to standarize data, but they would like a less expensive alternative. Are there any functions in SQL Server that I can use to standardized data?

  • BizTalk: Using context for routing

    - by Leonid Ganeline
    [See Sample: Context routing and throttling with orchestration] Imagine the project where most of the routing happens between orchestrations. I.e. routing is mostly between the MessageBox and orchestration with direct endpoints. Imagine also the most of the messages are with the same Message type. Usually in this case messages got the special node only for the routing. For example, the field can be the “Originator” or “Recipient” or “From” or “To”. What wrong is with this approach, it creates the dependency between the message and the message processing. Message “knows” something about Originator or Recipient. So what we can do with it? How can we “colorize” the same message to route it to the different places without changing the message itself? One of the decisions is to use the message context. BizTalk uses the promoted properties for routing.  There are two kinds of the properties: the content properties and the context properties. The content property extracts its value from inside the message, it is a value of the element or attribute. [See MSDN] The context property gets its value from the message environment. It can be the port name that receive this message, it can be the message Id, created by the BizTalk. Context properties look like the headers in the SOAP message. Actually they are not the headers but behave like headers. The context properties are the good match for our case. First, we don’t have to change the message itself to set or change the routing property. The context is stored outside the message body. Second, we don’t have to create the property schema to use the context properties. [See MSDN: How to create Property schema] BizTalk has the predefined schema set for the context properties. [See MSDN: Message Context Properties] Use one of them and that's it. The main purpose of the context properties is working on behalf of the BizTalk internals. But we can read, create and change them. Just do not interfere with BizTalk internals on this way.

  • Real Time Monitoring System using .net [closed]

    - by sameer
    I need to develop the application which display the dashboard where data from various SQL DB is fetched from different servers and displayed. Now this need to happen real time we can have refresh time say 5 min. Here is my thought, suggest if anything is wrong. 1) To Develop the Windows Service to accumulate the data from various SQL Server Instance. 2) Then Persist those details into SQL DB from which Dashboard will displayed on the web page. 3) Fetch of data from Windows service will be trigger every x minutes. 4) SQL Server Instance details will be stored in SQL DB which Windows Service will be referring. Thus this approach make sense. Thanks..

  • using GNU GPL v2 software as pointers to solution to problem

    - by Patrick
    I am coding a PHP serial access class and have been taking pointers from the PHP-serial class on Google Code (here). That class is based on PHP 4 and I'm creating a PHP 5 class that allows more functionality and is specific to some business demands I have. There is no code copied and I have done all the coding. Does the class I'm writing fall under the Google Code's GPL or am I free to select a license that I feel is appropriate? I'm not sure of the standard that applies to licensing when you are only looking to another work for pointers.

  • Resolution changes when using switch

    - by Edward D
    So, the "real" resolution of my monitor is 1024x768. That's what I'd use on my docked Windows laptop, and what I'd use on my Xubuntu desktop connected directly. When I connect a switch, to switch between the two, however, the ubuntu machine's resolution changes. Everything's still proportional, and it still thinks it's doing 1024x768, but the icons and fonts appear larger. Not 800x600 larger, but still big. When I used Xubuntu Precise, I created an xorg.conf file to set a resolution of 1280x1024 which made it look the way it does without the switch ... as a workaround. When I upgraded to Trusty, I lost this. I tried to re-create it, but doesn't seem to load my file. Ideally, I'd like to correct the original problem, but I'd settle for being able to up the resolution. I searched for a while, and tried to do it, but I'm giving up ... please help me out.

  • Using Unity – Part 4

    - by nmarun
    In this part, I’ll be discussing about constructor and property or setter injection. I’ve created a new class – Product3: 1: public class Product3 : IProduct 2: { 3: public string Name { get; set; } 4: [Dependency] 5: public IDistributor Distributor { get; set; } 6: public ILogger Logger { get; set; } 7:  8: public Product3(ILogger logger) 9: { 10: Logger = logger; 11: Name = "Product 1"; 12: } 13:  14: public string WriteProductDetails() 15: { 16: StringBuilder productDetails = new StringBuilder(); 17: productDetails.AppendFormat("{0}<br/>", Name); 18: productDetails.AppendFormat("{0}<br/>", Logger.WriteLog()); 19: productDetails.AppendFormat("{0}<br/>", Distributor.WriteDistributorDetails()); 20: return productDetails.ToString(); 21: } 22: } This version has a property of type IDistributor and takes a constructor parameter of type ILogger. The IDistributor property has a Dependency attribute (Microsoft.Practices.Unity namespace) applied to it. IDistributor and its implementation are shown below: 1: public interface IDistributor 2: { 3: string WriteDistributorDetails(); 4: } 5:  6: public class Distributor : IDistributor 7: { 8: public List<string> DistributorNames = new List<string>(); 9:  10: public Distributor() 11: { 12: DistributorNames.Add("Distributor1"); 13: DistributorNames.Add("Distributor2"); 14: DistributorNames.Add("Distributor3"); 15: DistributorNames.Add("Distributor4"); 16: } 17: public string WriteDistributorDetails() 18: { 19: StringBuilder distributors = new StringBuilder(); 20: for (int i = 0; i < DistributorNames.Count; i++) 21: { 22: distributors.AppendFormat("{0}<br/>", DistributorNames[i]); 23: } 24: return distributors.ToString(); 25: } 26: } ILogger and the FileLogger have the following definition: 1: public interface ILogger 2: { 3: string WriteLog(); 4: } 5:  6: public class FileLogger : ILogger 7: { 8: public string WriteLog() 9: { 10: return string.Format("Type: {0}", GetType()); 11: } 12: } The Unity container creates an instance of the dependent class (the Distributor class) within the scope of the target object (an instance of Product3 class that will be called by doing a Resolve<IProduct>() in the calling code) and assign this dependent object to the attributed property of the target object. To add to it, property injection is a form of optional injection of dependent objects.The dependent object instance is generated before the container returns the target object. Unlike constructor injection, you must apply the appropriate attribute in the target class to initiate property injection. Let’s see how to change the config file to make this work. The first step is to add all the type aliases: 1: <typeAlias alias="Product3" type="ProductModel.Product3, ProductModel"/> 2: <typeAlias alias="ILogger" type="ProductModel.ILogger, ProductModel"/> 3: <typeAlias alias="FileLogger" type="ProductModel.FileLogger, ProductModel"/> 4: <typeAlias alias="IDistributor" type="ProductModel.IDistributor, ProductModel"/> 5: <typeAlias alias="Distributor" type="ProductModel.Distributor, ProductModel"/> Now define mappings for these aliases: 1: <type type="ILogger" mapTo="FileLogger" /> 2: <type type="IDistributor" mapTo="Distributor" /> Next step is to define the constructor and property injection in the config file: 1: <type type="IProduct" mapTo="Product3" name="ComplexProduct"> 2: <typeConfig extensionType="Microsoft.Practices.Unity.Configuration.TypeInjectionElement, Microsoft.Practices.Unity.Configuration"> 3: <constructor> 4: <param name="logger" parameterType="ILogger" /> 5: </constructor> 6: <property name="Distributor" propertyType="IDistributor"> 7: <dependency /> 8: </property> 9: </typeConfig> 10: </type> There you see a constructor element that tells there’s a property named ‘logger’ that is of type ILogger. By default, the type of ILogger gets resolved to type FileLogger. There’s also a property named ‘Distributor’ which is of type IDistributor and which will get resolved to type Distributor. On the calling side, I’ve added a new button, whose click event does the following: 1: protected void InjectionButton_Click(object sender, EventArgs e) 2: { 3: unityContainer.RegisterType<IProduct, Product3>(); 4: IProduct product3 = unityContainer.Resolve<IProduct>(); 5: productDetailsLabel.Text = product3.WriteProductDetails(); 6: } This renders the following output: This completes the part for constructor and property injection. In the next blog, I’ll talk about Arrays and Generics. Please see the code used here.

  • Validate that a Checkbox is checked using javascript

    - by H(at)Ni
    I was facing a challenge yesterday that I was creating a Visual webpart and I wanted to validate the a submit button is only visible if the user checked a "I agree to terms" checkbox. Something was weired that I tested my code on a normal asp.net website and it worked perfectly while it had a different behaviour inside the webpart which is whenever I check the checkbox, the button is enabled but it will not fire the asp.net validators in client side. It posts back the page and then the validators appear after that. So, I tried to change my type of thinking and I reached a different solution is that to call a javascript function whenever the button is clicked and then check if the checkbox is clicked or not. To illustrate more, here are an example to what I'm saying: 1. Button in aspx page: <asp:Button OnClientClick="CheckForCondition();"  ValidationGroup="CompaniesSection" ID="btnCompaniesSubmit"                         runat="server" Text="Submit" /> 2. CheckForCondition() function: <script language="javascript" type="text/javascript">                         function CheckForCondition() {                             if ($jq('#<%= ChkCompanyCheck.ClientID %>:checked').val() == undefined) {                                 $jq('#lblCheckBox').show();                                 return false;                             }                             else {                                 $jq('#lblCheckBox').hide();                                 return true;                             }                         }                      </script> 3. lblCheckBox is simply a label that shows a red asterisk beside the checkbox to indicate that it's a required field. <label id="lblCheckBox" style="color:Red;display:none">*</label>

  • Using Google App Engine to Perform World Updates vs an Authoritative Server

    - by Error 454
    I am considering different game server architectures that use GAE. The types of games I am considering are turn-based where the world status would need to be updated about once per minute. I am looking for an answer that persuades me to either perform the world update on the google servers OR an authoritative server that syncs with the datastore. The main goal here would be to minimize GAE daily quotas. For some rough numbers, I am assuming 10,000 entities requiring updates. Each entity update would require: Reading 5 private entity variables (fetched from datastore) Fetching as many as 20 static variables (from datastore or persisted in server memory) Writing 5 entity variables Clients of the game would authenticate and set state directly against GAE as well as pull the latest world state from GAE. Running the update on GAE would consist of a cron job launched every minute. This would update all of the entities and save the results to the datastore. This would be more CPU intensive for GAE. Running the update on an authoritative server would consist of fetching entity data from the GAE datastore, calculating the new entity states and pushing the new state variables back to the datastore. This would be more bandwidth intensive for the datastore.

  • Using glReadBuffer returns black image instead of the actual image only on Intel cards

    - by cloudraven
    I have this piece of code glReadBuffer( GL_FRONT ); glReadPixels( 0, 0, width, height, GL_RGB, GL_UNSIGNED_BYTE, buffer ); Which works just perfectly in all the Nvidia and AMD GPUs I have tried, but it fails in almost every single Intel built-in video that I have tried. It actually works in a very old 945GME, but fails in all the others. Instead of getting a screenshot I am actually getting a black screen. If it helps, I am working with the Doom3 Engine, and that code is derived from the built-in screen capture code. By the way, even with the original game I cannot do screen capture on those intel devices anyway. My guess is that they are not implementing the standard correctly or something. Is there a workaround for this?

  • HTML5-Canvas: worth using ImpactJS or other framework?

    - by John
    I've been making an HTML5 game without any type of external framework. I haven't found a reason to use one so far. However, there is one thing I'm wondering about. On my Galaxy Nexus, I get about ~40fps. While that would usually be a decent framerate, my game is a rather fast paced game with a gamepad. Because of this, it feels very unsatisfying to play when not capped at 60fps. Are there frameworks out there that can improve performance without toning down on graphics? Or is there something I could do myself without necessarily having to use a framework? I've looked over the basic things such as sticking to integer coordinates, but I didn't see an increase in performance whatsoever? I did some testing with jsperf and results were virtually identical. Does this depend more on the browser?
