  • jQuery CSS Custom Flyout Menu Styling Issue

    - by aherrick
    I'm close to nailing this flyout menu I have been working on, just have a couple of current pain points. I'm trying to get left/right padding on my submenu items, as you can see I am not quite there. Also when the first submenu is displayed, I want to create a bit of a gap between the first row of list items and the child. Below is my current code and a screen shot displaying what I want.

  • Formatting minified jQuery, JavaScript using the Internet Explorer 9 Developer Toolbar

    - by Harish Ranganathan
    Much has been talked about the F12 developer toolbar in IE and the support it provides for web developers.  Starting IE8, the Developer Toolbar is a menu item that helps you view the page source, scripts, profiling and many other details of the rendered page.  It even allows script debugging from within and that makes it a truly powerful web developer tool bar. With IE9, the developer toolbar got even better with the Networking Tab that allows you to inspect the traffic/time taken and drill down into the Request/Response headers and other specifics. The script tab allows you to view the scripts used in the page. One of the challenges of working with JavaScript / jQuery when they are minified, is that, it becomes really hard to read.  Minified JavaScript is a compression technique and also a best practice for delivering faster web pages.  However, when you would like to debug, minified JavaScript files become very hard since they aren't properly formatted.  Take the case of the above sample, which is a basic MVC 3 Web Application.  It uses the minified jQuery and modernizr files. Once we select the above scripts, the script source looks as follows:- But with the “Format JavaScript” option in the Configuration icon, Once you click on the “Format JavaScript”, you can see the formatted JavaScript as per screen below:- This makes the script readable and also easy for debugging.  Cheers !!!

  • Nashorn, the rhino in the room

    - by costlow
    Nashorn is a new runtime within JDK 8 that allows developers to run code written in JavaScript and call back and forth with Java. One advantage to the Nashorn scripting engine is that is allows for quick prototyping of functionality or basic shell scripts that use Java libraries. The previous JavaScript runtime, named Rhino, was introduced in JDK 6 (released 2006, end of public updates Feb 2013). Keeping tradition amongst the global developer community, "Nashorn" is the German word for rhino. The Java platform and runtime is an intentional home to many languages beyond the Java language itself. OpenJDK’s Da Vinci Machine helps coordinate work amongst language developers and tool designers and has helped different languages by introducing the Invoke Dynamic instruction in Java 7 (2011), which resulted in two major benefits: speeding up execution of dynamic code, and providing the groundwork for Java 8’s lambda executions. Many of these improvements are discussed at the JVM Language Summit, where language and tool designers get together to discuss experiences and issues related to building these complex components. There are a number of benefits to running JavaScript applications on JDK 8’s Nashorn technology beyond writing scripts quickly: Interoperability with Java and JavaScript libraries. Scripts do not need to be compiled. Fast execution and multi-threading of JavaScript running in Java’s JRE. The ability to remotely debug applications using an IDE like NetBeans, Eclipse, or IntelliJ (instructions on the Nashorn blog). Automatic integration with Java monitoring tools, such as performance, health, and SIEM. In the remainder of this blog post, I will explain how to use Nashorn and the benefit from those features. Nashorn execution environment The Nashorn scripting engine is included in all versions of Java SE 8, both the JDK and the JRE. Unlike Java code, scripts written in nashorn are interpreted and do not need to be compiled before execution. Developers and users can access it in two ways: Users running JavaScript applications can call the binary directly:jre8/bin/jjs This mechanism can also be used in shell scripts by specifying a shebang like #!/usr/bin/jjs Developers can use the API and obtain a ScriptEngine through:ScriptEngine engine = new ScriptEngineManager().getEngineByName("nashorn"); When using a ScriptEngine, please understand that they execute code. Avoid running untrusted scripts or passing in untrusted/unvalidated inputs. During compilation, consider isolating access to the ScriptEngine and using Type Annotations to only allow @Untainted String arguments. One noteworthy difference between JavaScript executed in or outside of a web browser is that certain objects will not be available. For example when run outside a browser, there is no access to a document object or DOM tree. Other than that, all syntax, semantics, and capabilities are present. Examples of Java and JavaScript The Nashorn script engine allows developers of all experience levels the ability to write and run code that takes advantage of both languages. The specific dialect is ECMAScript 5.1 as identified by the User Guide and its standards definition through ECMA international. In addition to the example below, Benjamin Winterberg has a very well written Java 8 Nashorn Tutorial that provides a large number of code samples in both languages. Basic Operations A basic Hello World application written to run on Nashorn would look like this: #!/usr/bin/jjs print("Hello World"); The first line is a standard script indication, so that Linux or Unix systems can run the script through Nashorn. On Windows where scripts are not as common, you would run the script like: jjs helloWorld.js. Receiving Arguments In order to receive program arguments your jjs invocation needs to use the -scripting flag and a double-dash to separate which arguments are for jjs and which are for the script itself:jjs -scripting print.js -- "This will print" #!/usr/bin/jjs var whatYouSaid = $ARG.length==0 ? "You did not say anything" : $ARG[0] print(whatYouSaid); Interoperability with Java libraries (including 3rd party dependencies) Another goal of Nashorn was to allow for quick scriptable prototypes, allowing access into Java types and any libraries. Resources operate in the context of the script (either in-line with the script or as separate threads) so if you open network sockets and your script terminates, those sockets will be released and available for your next run. Your code can access Java types the same as regular Java classes. The “import statements” are written somewhat differently to accommodate for language. There is a choice of two styles: For standard classes, just name the class: var ServerSocket = java.net.ServerSocket For arrays or other items, use Java.type: var ByteArray = Java.type("byte[]")You could technically do this for all. The same technique will allow your script to use Java types from any library or 3rd party component and quickly prototype items. Building a user interface One major difference between JavaScript inside and outside of a web browser is the availability of a DOM object for rendering views. When run outside of the browser, JavaScript has full control to construct the entire user interface with pre-fabricated UI controls, charts, or components. The example below is a variation from the Nashorn and JavaFX guide to show how items work together. Nashorn has a -fx flag to make the user interface components available. With the example script below, just specify: jjs -fx -scripting fx.js -- "My title" #!/usr/bin/jjs -fx var Button = javafx.scene.control.Button; var StackPane = javafx.scene.layout.StackPane; var Scene = javafx.scene.Scene; var clickCounter=0; $STAGE.title = $ARG.length>0 ? $ARG[0] : "You didn't provide a title"; var button = new Button(); button.text = "Say 'Hello World'"; button.onAction = myFunctionForButtonClicking; var root = new StackPane(); root.children.add(button); $STAGE.scene = new Scene(root, 300, 250); $STAGE.show(); function myFunctionForButtonClicking(){   var text = "Click Counter: " + clickCounter;   button.setText(text);   clickCounter++;   print(text); } For a more advanced post on using Nashorn to build a high-performing UI, see JavaFX with Nashorn Canvas example. Interoperable with frameworks like Node, Backbone, or Facebook React The major benefit of any language is the interoperability gained by people and systems that can read, write, and use it for interactions. Because Nashorn is built for the ECMAScript specification, developers familiar with JavaScript frameworks can write their code and then have system administrators deploy and monitor the applications the same as any other Java application. A number of projects are also running Node applications on Nashorn through Project Avatar and the supported modules. In addition to the previously mentioned Nashorn tutorial, Benjamin has also written a post about Using Backbone.js with Nashorn. To show the multi-language power of the Java Runtime, there is another interesting example that unites Facebook React and Clojure on JDK 8’s Nashorn. Summary Nashorn provides a simple and fast way of executing JavaScript applications and bridging between the best of each language. By making the full range of Java libraries to JavaScript applications, and the quick prototyping style of JavaScript to Java applications, developers are free to work as they see fit. Software Architects and System Administrators can take advantage of one runtime and leverage any work that they have done to tune, monitor, and certify their systems. Additional information is available within: The Nashorn Users’ Guide Java Magazine’s article "Next Generation JavaScript Engine for the JVM." The Nashorn team’s primary blog or a very helpful collection of Nashorn links.

  • My app has some basic problems, and it stops working

    - by user2882662
    I am writing a basic application which contains two activities. Both contain a TextView showing the title and the first one contains an EditText in which the user types a message and clicks on a button on its side, the second activity is launched which shows the message the user types. It has the following problems: The title (the first TextView in both the activities) doesn't show in the middle of the line, despite of the android:gravity="center_horizontal" attribute. The EditText in the first activity does not show at all. When I click on the button, the app stops saying "Unfortunately Write n Display and stopped.", rather than launching the second activity at all. I don't have adequate knowledge about logcat, but I have followed the steps somebody had told me, that is WindowOpen Perspective Other DDMS Then run the app and select the package name from the Devices and click on log cat, select the exception(s) and export to text file. All contained in the text file is : : E/(): Device disconnected: 1 Since I am not sure of using log cat, so I am posting a screenshot to make clear what I have done.

  • White Paper on Analysis Services Tabular Large-scale Solution #ssas #tabular

    - by Marco Russo (SQLBI)
    Since the first beta of Analysis Services 2012, I worked with many companies designing and implementing solutions based on Analysis Services Tabular. I am glad that Microsoft published a white paper about a case-study using one of these scenarios: An Analysis Services Case Study: Using Tabular Models in a Large-scale Commercial Solution. Alberto Ferrari is the author of the white paper and many people contributed to it. The final result is a very technical document based on a case study, which provides a level of detail that I don’t see often in other case studies (which are usually more marketing-oriented). This white paper has the following structure: Requirements (data model, capacity planning, client tool) Options considered (SQL Server Columnstore Indexes, SSAS Multidimensional, SSAS Tabular) Data Model optimizations (memory compression, query performance, scalability) Partitioning and Processing strategy for near real-time latency Hardware selection (NUMA analysis, Azure VM tests) Scalability tests (estimation of maximum users per node) If you are in charge of evaluating Tabular as analytical engine, or if you have to design your solution based on Tabular, this white paper is a must read. But if you just want to increase your knowledge of Analysis Services, you will find a lot of useful technical information. That said, my favorite quote of the document is the following one, funny but true: […] After several trials, the clear winner was a video gaming machine that one guy on the team used at home. That computer outperformed any available server, running twice as fast as the server-class machines we had in house. At that point, it was clear that the criteria for choosing the server would have to be expanded a bit, simply because it would have been impossible to convince the boss to build a cluster of gaming machines and trust it to serve our customers.  But, honestly, if a business has the flexibility to buy gaming machines (assuming the machines can handle capacity) – do this. Owen Graupman, inContact I want to write a longer discussion about how companies are adopting Tabular in scenarios where it is the hidden engine of a more complex solution (and not the classical “BI system”), because it is more frequent than you might expect (and has several advantages over many alternative approaches).

  • A story from SQLvdb and Idera

    - by Peter Larsson
    A year or so back, I struggled with some consistency problems so I figured out I needed a way to "mount" backup files as a virtual database. At the time (SQL Server 2005 and SQL Server 2008) my choice fell on Idera's SQLvdb because it felt easy enough to use. I used it a few times and it worked great. Some time later we upgraded to SQL Server 2008R2 and I didn't use SQLvbd for a long time. Until yesterday... I was upset that suddenly SQLvbd took more than 2 hours to mount the backup file (if it succeeded at all). I uninstalled the application and went for lunch. After lunch, I decided to give SQLvbd another chance so I emailed their tech support and got a response within 30 minutes or so. Now, since I am a SQL Server MVP, they gave me another serial number than my first and I downloaded and installed a newer version. But also this version was really slow. I emailed back to them with the additional information they requested and to my surprise I had got an email this morning when I came back to work, where Idera explained some of the issues (bugs) and asked my to test a newer version. I did, and now a fresh mount of a 100GB database (compressed to 20GB with native compression) located on our SAN takes less than 6 minutes! Thank you. //Peter

  • How to use ULS in SharePoint 2010 for Custom Code Exception Logging?

    - by venkatx5
    What is ULS in SharePoint 2010? ULS stands for Unified Logging Service which captures and writes Exceptions/Logs in Log File(A Plain Text File with .log extension). SharePoint logs Each and every exceptions with ULS. SharePoint Administrators should know ULS and it's very useful when anything goes wrong. but when you ask any SharePoint 2007 Administrator to check log file then most of them will Kill you. Because read and understand the log file is not so easy. Imagine open a plain text file of 20 MB in NotePad and go thru line by line. Now Microsoft developed a tool "ULS Viewer" to view those Log files in easily readable format. This tools also helps to filter events based on exception priority. You can read on this blog to know in details about ULS Viewer . Where to get ULS Viewer? ULS Viewer is developed by Microsoft and available to download for free. URL : http://code.msdn.microsoft.com/ULSViewer/Release/ProjectReleases.aspx?ReleaseId=3308 Note: Eventhought this tool developed by Microsoft, it's not supported by Microsoft. Means you can't support for this tool from Microsoft and use it on your own Risk. By the way what's the risk in viewing Log Files?! How to use ULS in SharePoint 2010 Custom Code? ULS can be extended to use in user solutions to log exceptions. In Detail, Developer can use ULS to log his own application errors and exceptions on SharePoint Log files. So now all in Single Place (That's why it's called "Unified Logging"). Well in this article I am going to use Waldek's Code (Reference Link). However the article is core and am writing container for that (Basically how to implement the code in Detail). Let's see the steps. Open Visual Studio 2010 -> File -> New Project -> Visual C# -> Windows -> Class Library -> Name : ULSLogger (Make sure you've selected .net Framework 3.5)   In Solution Explorer Panel, Rename the Class1.cs to LoggingService.cs   Right Click on References -> Add Reference -> Under .Net tab select "Microsoft.SharePoint"   Right Click on the Project -> Properties. Select "Signing" Tab -> Check "Sign the Assembly".   In the below drop down select <New> and enter "ULSLogger", uncheck the "Protect my key with a Password" option.   Now copy the below code and paste. (Or Just refer.. :-) ) using System; using System.Collections.Generic; using System.Linq; using System.Text; using Microsoft.SharePoint; using Microsoft.SharePoint.Administration; using System.Runtime.InteropServices; namespace ULSLogger { public class LoggingService : SPDiagnosticsServiceBase { public static string vsDiagnosticAreaName = "Venkats SharePoint Logging Service"; public static string CategoryName = "vsProject"; public static uint uintEventID = 700; // Event ID private static LoggingService _Current; public static LoggingService Current {  get   {    if (_Current == null)     {       _Current = new LoggingService();     }    return _Current;   } }private LoggingService() : base("Venkats SharePoint Logging Service", SPFarm.Local) {}protected override IEnumerable<SPDiagnosticsArea> ProvideAreas() { List<SPDiagnosticsArea> areas = new List<SPDiagnosticsArea>  {   new SPDiagnosticsArea(vsDiagnosticAreaName, new List<SPDiagnosticsCategory>    {     new SPDiagnosticsCategory(CategoryName, TraceSeverity.Medium, EventSeverity.Error)    })   }; return areas; }public static string LogErrorInULS(string errorMessage) { string strExecutionResult = "Message Not Logged in ULS. "; try  {   SPDiagnosticsCategory category = LoggingService.Current.Areas[vsDiagnosticAreaName].Categories[CategoryName];   LoggingService.Current.WriteTrace(uintEventID, category, TraceSeverity.Unexpected, errorMessage);   strExecutionResult = "Message Logged"; } catch (Exception ex) {  strExecutionResult += ex.Message; } return strExecutionResult; }public static string LogErrorInULS(string errorMessage, TraceSeverity tsSeverity) { string strExecutionResult = "Message Not Logged in ULS. "; try  {  SPDiagnosticsCategory category = LoggingService.Current.Areas[vsDiagnosticAreaName].Categories[CategoryName];  LoggingService.Current.WriteTrace(uintEventID, category, tsSeverity, errorMessage);  strExecutionResult = "Message Logged";  } catch (Exception ex)  {   strExecutionResult += ex.Message;   } return strExecutionResult;  } } }   Just build the solution and it's ready to use now. This ULS solution can be used in SharePoint Webparts or Console Application. Lets see how to use it in a Console Application. SharePoint Server 2010 must be installed in the same Server or the application must be hosted in SharPoint Server 2010 environment. The console application must be set to "x64" Platform target.   Create a New Console Application. (Visual Studio -> File -> New Project -> C# -> Windows -> Console Application) Right Click on References -> Add Reference -> Under .Net tab select "Microsoft.SharePoint" Open Program.cs add "using Microsoft.SharePoint.Administration;" Right Click on References -> Add Reference -> Under "Browse" tab select the "ULSLogger.dll" which we created first. (Path : ULSLogger\ULSLogger\bin\Debug\) Right Click on Project -> Properties -> Select "Build" Tab -> Under "Platform Target" option select "x64". Open the Program.cs and paste the below code. using System; using System.Collections.Generic; using System.Linq; using System.Text; using Microsoft.SharePoint.Administration; using ULSLogger; namespace ULSLoggerClient {  class Program   {   static void Main(string[] args)     {     Console.WriteLine("ULS Logging Started.");     string strResult = LoggingService.LogErrorInULS("My Application is Working Fine.");      Console.WriteLine("ULS Logging Info. Result : " + strResult);     string strResult = LoggingService.LogErrorInULS("My Application got an Exception.", TraceSeverity.High);     Console.WriteLine("ULS Logging Waring Result : " + strResult);      Console.WriteLine("ULS Logging Completed.");      Console.ReadLine();     }   } } Just build the solution and execute. It'll log the message on the log file. Make sure you are using Farm Administrator User ID. You can play with Message and TraceSeverity as required. Now Open ULS Viewer -> File -> Open From -> ULS -> Select First Option to open the default ULS Log. It's Uls RealTime and will show all log entries in readable table format. Right Click on a row and select "Filter By This Item". Select "Event ID" and enter value "700" that we used in the application. Click Ok and now you'll see the Exceptions/Logs which logged by our application.   If you want to see High Priority Messages only then Click Icons except Red Cross Icon on the Toolbar. The tooltip will tell what's the icons used for.

  • How was Git designed?

    - by Mark Canlas
    My workplace recently switched to Git and I've been loving (and hating!) it. I really do love it, and it is extremely powerful. The only part I hate is that sometimes it's too powerful (and maybe a bit terse/confusing). My question is... How was Git designed? Just using it for a short amount of time, you get the feel that it can handle many obscure workflows that other version control systems could not. But it also feels elegant underneath. And fast! This is no doubt in part to Linus's talent. But I'm wondering, was the overall design of git based off of something? I've read about BitKeeper but the accounts are scant on technical details. The compression, the graphs, getting rid of revision numbers, emphasizing branching, stashing, remotes... Where did it all come from? Linus really knocked this one out of the park and on pretty much the first try! It's quite good to use once you're past the learning curve.

  • Possible to manipulate UI elements via dispatchEvent()?

    - by rinogo
    Hi all! I'm trying to manually dispatch events on a textfield so I can manipulate it indirectly via code (e.g. place cursor at a given set of x/y coordinates). However, my events seem to have no effect. I've written a test to experiment with this phenomenon: package sandbox { import flash.display.Sprite; import flash.events.MouseEvent; import flash.text.TextField; import flash.text.TextFieldType; import flash.text.TextFieldAutoSize; import flash.utils.setTimeout; public class Test extends Sprite { private var tf:TextField; private var tf2:TextField; public function Test() { super(); tf = new TextField(); tf.text = 'Interact here'; tf.type = TextFieldType.INPUT; addChild(tf); tf2 = new TextField(); tf2.text = 'Same events replayed with five second delay here'; tf2.autoSize = TextFieldAutoSize.LEFT; tf2.type = TextFieldType.INPUT; tf2.y = 30; addChild(tf2); tf.addEventListener(MouseEvent.CLICK, mouseListener); tf.addEventListener(MouseEvent.DOUBLE_CLICK, mouseListener); tf.addEventListener(MouseEvent.MOUSE_DOWN, mouseListener); tf.addEventListener(MouseEvent.MOUSE_MOVE, mouseListener); tf.addEventListener(MouseEvent.MOUSE_OUT, mouseListener); tf.addEventListener(MouseEvent.MOUSE_OVER, mouseListener); tf.addEventListener(MouseEvent.MOUSE_UP, mouseListener); tf.addEventListener(MouseEvent.MOUSE_WHEEL, mouseListener); tf.addEventListener(MouseEvent.ROLL_OUT, mouseListener); tf.addEventListener(MouseEvent.ROLL_OVER, mouseListener); } private function mouseListener(event:MouseEvent):void { //trace(event); setTimeout(function():void {trace(event); tf2.dispatchEvent(event);}, 5000); } } } Essentially, all this test does is to use setTimeout to effectively 'record' events on TextField tf and replay them five seconds later on TextField tf2. When an event is dispatched on tf2, it is traced to the console output. The console output upon running this program and clicking on tf is: [MouseEvent type="mouseMove" bubbles=true cancelable=false eventPhase=3 localX=0 localY=1 stageX=0 stageY=1 relatedObject=null ctrlKey=false altKey=false shiftKey=false delta=0] [MouseEvent type="rollOver" bubbles=false cancelable=false eventPhase=2 localX=0 localY=1 stageX=0 stageY=1 relatedObject=null ctrlKey=false altKey=false shiftKey=false delta=0] [MouseEvent type="mouseOver" bubbles=true cancelable=false eventPhase=3 localX=0 localY=1 stageX=0 stageY=1 relatedObject=null ctrlKey=false altKey=false shiftKey=false delta=0] [MouseEvent type="mouseMove" bubbles=true cancelable=false eventPhase=3 localX=2 localY=1 stageX=2 stageY=1 relatedObject=null ctrlKey=false altKey=false shiftKey=false delta=0] [MouseEvent type="mouseMove" bubbles=true cancelable=false eventPhase=3 localX=2 localY=2 stageX=2 stageY=2 relatedObject=null ctrlKey=false altKey=false shiftKey=false delta=0] [MouseEvent type="mouseMove" bubbles=true cancelable=false eventPhase=3 localX=2 localY=3 stageX=2 stageY=3 relatedObject=null ctrlKey=false altKey=false shiftKey=false delta=0] [MouseEvent type="mouseMove" bubbles=true cancelable=false eventPhase=3 localX=3 localY=3 stageX=3 stageY=3 relatedObject=null ctrlKey=false altKey=false shiftKey=false delta=0] [MouseEvent type="mouseMove" bubbles=true cancelable=false eventPhase=3 localX=5 localY=3 stageX=5 stageY=3 relatedObject=null ctrlKey=false altKey=false shiftKey=false delta=0] [MouseEvent type="mouseMove" bubbles=true cancelable=false eventPhase=3 localX=6 localY=5 stageX=6 stageY=5 relatedObject=null ctrlKey=false altKey=false shiftKey=false delta=0] [MouseEvent type="mouseMove" bubbles=true cancelable=false eventPhase=3 localX=7 localY=5 stageX=7 stageY=5 relatedObject=null ctrlKey=false altKey=false shiftKey=false delta=0] [MouseEvent type="mouseMove" bubbles=true cancelable=false eventPhase=3 localX=9 localY=5 stageX=9 stageY=5 relatedObject=null ctrlKey=false altKey=false shiftKey=false delta=0] [MouseEvent type="mouseMove" bubbles=true cancelable=false eventPhase=3 localX=10 localY=5 stageX=10 stageY=5 relatedObject=null ctrlKey=false altKey=false shiftKey=false delta=0] [MouseEvent type="mouseMove" bubbles=true cancelable=false eventPhase=3 localX=11 localY=5 stageX=11 stageY=5 relatedObject=null ctrlKey=false altKey=false shiftKey=false delta=0] [MouseEvent type="mouseMove" bubbles=true cancelable=false eventPhase=3 localX=12 localY=5 stageX=12 stageY=5 relatedObject=null ctrlKey=false altKey=false shiftKey=false delta=0] [MouseEvent type="mouseDown" bubbles=true cancelable=false eventPhase=3 localX=12 localY=5 stageX=12 stageY=5 relatedObject=null ctrlKey=false altKey=false shiftKey=false delta=0] [MouseEvent type="mouseUp" bubbles=true cancelable=false eventPhase=3 localX=12 localY=5 stageX=12 stageY=5 relatedObject=null ctrlKey=false altKey=false shiftKey=false delta=0] [MouseEvent type="click" bubbles=true cancelable=false eventPhase=3 localX=12 localY=5 stageX=12 stageY=5 relatedObject=null ctrlKey=false altKey=false shiftKey=false delta=0] [MouseEvent type="mouseMove" bubbles=true cancelable=false eventPhase=3 localX=10 localY=4 stageX=10 stageY=4 relatedObject=null ctrlKey=false altKey=false shiftKey=false delta=0] [MouseEvent type="mouseMove" bubbles=true cancelable=false eventPhase=3 localX=9 localY=2 stageX=9 stageY=2 relatedObject=null ctrlKey=false altKey=false shiftKey=false delta=0] [MouseEvent type="mouseMove" bubbles=true cancelable=false eventPhase=3 localX=9 localY=1 stageX=9 stageY=1 relatedObject=null ctrlKey=false altKey=false shiftKey=false delta=0] [MouseEvent type="mouseOut" bubbles=true cancelable=false eventPhase=3 localX=-1 localY=-1 stageX=-1 stageY=-1 relatedObject=null ctrlKey=false altKey=false shiftKey=false delta=0] [MouseEvent type="rollOut" bubbles=false cancelable=false eventPhase=2 localX=-1 localY=-1 stageX=-1 stageY=-1 relatedObject=null ctrlKey=false altKey=false shiftKey=false delta=0] As we can see, the events are being captured and replayed successfully. However, no change occurs in tf2 - the mouse cursor does not appear in tf2 as we would expect. In fact, the cursor remains in tf even after the tf2 events are dispatched. Please help! Thanks, -Rich

  • MVVM - implementing 'IsDirty' functionality to a ModelView in order to save data

    - by Brendan
    Hi, Being new to WPF & MVVM I struggling with some basic functionality. Let me first explain what I am after, and then attach some example code... I have a screen showing a list of users, and I display the details of the selected user on the right-hand side with editable textboxes. I then have a Save button which is DataBound, but I would only like this button to display when data has actually changed. ie - I need to check for "dirty data". I have a fully MVVM example in which I have a Model called User: namespace Test.Model { class User { public string UserName { get; set; } public string Surname { get; set; } public string Firstname { get; set; } } } Then, the ViewModel looks like this: using System.Collections.ObjectModel; using System.Collections.Specialized; using System.Windows.Input; using Test.Model; namespace Test.ViewModel { class UserViewModel : ViewModelBase { //Private variables private ObservableCollection<User> _users; RelayCommand _userSave; //Properties public ObservableCollection<User> User { get { if (_users == null) { _users = new ObservableCollection<User>(); //I assume I need this Handler, but I am stuggling to implement it successfully //_users.CollectionChanged += HandleChange; //Populate with users _users.Add(new User {UserName = "Bob", Firstname="Bob", Surname="Smith"}); _users.Add(new User {UserName = "Smob", Firstname="John", Surname="Davy"}); } return _users; } } //Not sure what to do with this?!?! //private void HandleChange(object sender, NotifyCollectionChangedEventArgs e) //{ // if (e.Action == NotifyCollectionChangedAction.Remove) // { // foreach (TestViewModel item in e.NewItems) // { // //Removed items // } // } // else if (e.Action == NotifyCollectionChangedAction.Add) // { // foreach (TestViewModel item in e.NewItems) // { // //Added items // } // } //} //Commands public ICommand UserSave { get { if (_userSave == null) { _userSave = new RelayCommand(param => this.UserSaveExecute(), param => this.UserSaveCanExecute); } return _userSave; } } void UserSaveExecute() { //Here I will call my DataAccess to actually save the data } bool UserSaveCanExecute { get { //This is where I would like to know whether the currently selected item has been edited and is thus "dirty" return false; } } //constructor public UserViewModel() { } } } The "RelayCommand" is just a simple wrapper class, as is the "ViewModelBase". (I'll attach the latter though just for clarity) using System; using System.ComponentModel; namespace Test.ViewModel { public abstract class ViewModelBase : INotifyPropertyChanged, IDisposable { protected ViewModelBase() { } public event PropertyChangedEventHandler PropertyChanged; protected virtual void OnPropertyChanged(string propertyName) { PropertyChangedEventHandler handler = this.PropertyChanged; if (handler != null) { var e = new PropertyChangedEventArgs(propertyName); handler(this, e); } } public void Dispose() { this.OnDispose(); } protected virtual void OnDispose() { } } } Finally - the XAML <Window x:Class="Test.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:vm="clr-namespace:Test.ViewModel" Title="MainWindow" Height="350" Width="525"> <Window.DataContext> <vm:UserViewModel/> </Window.DataContext> <Grid> <ListBox Height="238" HorizontalAlignment="Left" Margin="12,12,0,0" Name="listBox1" VerticalAlignment="Top" Width="197" ItemsSource="{Binding Path=User}" IsSynchronizedWithCurrentItem="True"> <ListBox.ItemTemplate> <DataTemplate> <StackPanel> <TextBlock Text="{Binding Path=Firstname}"/> <TextBlock Text="{Binding Path=Surname}"/> </StackPanel> </DataTemplate> </ListBox.ItemTemplate> </ListBox> <Label Content="Username" Height="28" HorizontalAlignment="Left" Margin="232,16,0,0" Name="label1" VerticalAlignment="Top" /> <TextBox Height="23" HorizontalAlignment="Left" Margin="323,21,0,0" Name="textBox1" VerticalAlignment="Top" Width="120" Text="{Binding Path=User/UserName}" /> <Label Content="Surname" Height="28" HorizontalAlignment="Left" Margin="232,50,0,0" Name="label2" VerticalAlignment="Top" /> <TextBox Height="23" HorizontalAlignment="Left" Margin="323,52,0,0" Name="textBox2" VerticalAlignment="Top" Width="120" Text="{Binding Path=User/Surname}" /> <Label Content="Firstname" Height="28" HorizontalAlignment="Left" Margin="232,84,0,0" Name="label3" VerticalAlignment="Top" /> <TextBox Height="23" HorizontalAlignment="Left" Margin="323,86,0,0" Name="textBox3" VerticalAlignment="Top" Width="120" Text="{Binding Path=User/Firstname}" /> <Button Content="Button" Height="23" HorizontalAlignment="Left" Margin="368,159,0,0" Name="button1" VerticalAlignment="Top" Width="75" Command="{Binding Path=UserSave}" /> </Grid> </Window> So basically, when I edit a surname, the Save button should be enabled; and if I undo my edit - well then it should be Disabled again as nothing has changed. I have seen this in many examples, but have not yet found out how to do it. Any help would be much appreciated! Brendan

  • Unable to Start Activity ComponentInfo when Starting a New Activity

    - by Timtim17
    {I know there's already a whole bunch of questions like this, but I can't see any problems that related to my program.} I have an Android App that is supposed to take a name from a EditText and put it in a TextView in another activity. It previously worked, but then I wanted it to start another activity if the EditText's value was equal to "ANDROID". However, now the app crashes whenever I try to start either activity. First Activity: package net.timtim17.dev.android.fun.nametag; import android.os.Bundle; import android.app.Activity; import android.content.Intent; import android.view.View; import android.view.View.OnClickListener;

  • Linux to Solaris @ Morgan Stanley

    - by mgerdts
    I came across this blog entry and the accompanying presentation by Robert Milkoski about his experience switching from Linux to Oracle Solaris 11 for a distributed OpenAFS file serving environment at Morgan Stanley. If you are an IT manager, the presentation will show you: Running Solaris with a support contract can cost less than running Linux (even without a support contract) because of technical advantages of Solaris. IT departments can benefit from hiring computer scientists into Systems Programmer or similar roles.  Their computer science background should be nurtured so that they can continue to deliver value (savings and opportunity) to the business as technology advances. If you are a sysadmin, developer, or somewhere in between, the presentation will show you: A presentation that explains your technical analysis can be very influential. Learning and using the non-default options of an OS can make all the difference as to whether one OS is better suited than another.  For example, see the graphs on slides 3 - 5.  The ZFS default is to not use compression. When trying to convince those that hold the purse strings that your technical direction should be taken, the financial impact can be the part that closes the deal.  See slides 6, 9, and 10.  Sometimes reducing rack space requirements can be the biggest impact because it may stave off or completely eliminate the need for facilities growth. DTrace can be used to shine light on performance problems that may be suspected but not diagnosed.  It is quite likely that these problems have existed in OpenAFS for a decade or more.  DTrace made diagnosis possible. DTrace can be used to create performance analysis tools without modifying the source of software that is under analysis.  See slides 29 - 32. Microstate accounting, visible in the prstat output on slide 37 can be used to quickly draw focus to problem areas that affect CPU saturation.  Note that prstat without -m gives a time-decayed moving average that is not nearly as useful. Instruction level probes (slides 33 - 34) are a super-easy way to identify which part of a function is hot.

    source Eva Mendez says, "Oye chico, do you really want to keep your data in that tired legacy file system when it could be enjoying encryption, compression, deduplication, snapshots, remote replication and other benefits provided by ZFS in Oracle Solaris 11? It's really not that hard to cross over. If you know how." "I don't know how, me dices? Esta bien, papacito. Go to OTN. Take my word for it. They know how." <blushing> Aw shucks, Eva.

  • Convenience of mySQL over xml

    - by Bonechilla
    Currently I use XML to store specific information to correctly load a few things such as a list of specfied characters, scenes and music, Once more I use JAXB in combination with standard compression/decompression(ZIP) functionality to store a list of extrenous data. This data is called to add functionality to the character, somewhat like Skills in an RPG. Each skill is seperated into its own XML file with a grandlist which contains the names of each file with their extensions omitted and zipped in folder that gets encrypted. At first using xml was working fine however as the skill list grow i worry about its stability. I was wondering if I should begin storing the data in mySQL. Originally I planned to simply convert everything to JSON over xml but i think possibly mySQL would be a better move. Can anyone inform me of the key difference and pros and cons of each I guess i'm looking for the best way to store the data more conviently and would be easier to operate on. The data is mostly primatives and strings and the only arraylist of values i have i can just concat into a single field and parse later Edit: If I am going in the right direction with XML would it make sense to convert it to JSON and use maybe Kyro or EclipseLink JAXB (MOXy)

  • How to set Grub to automatically load Xen kernel

    - by Cerin
    How do you configure Grub to automatically use the Xen kernel under Ubuntu 11.10? No matter what I do, it loads the first menuentry. The only way I can get it to load Xen is to manually select the kernel, which I can't do if I have to reboot the server remotely, or there's a power failure and the machine automatically boots up when power's restored, etc. It's driving me nuts. In my /boot/grub/grub.cfg, the Xen kernel is at index 4 (i.e. it's the 5th menuentry). So I've tried: Setting GRUB_DEFAULT=4, and running sudo update-grub Setting GRUB_DEFAULT=saved and GRUB_SAVEDEFAULT=true, and running sudo update-grub Setting GRUB_DEFAULT="Ubuntu GNU/Linux, with Xen 4.1-amd64 and Linux 3.0.0-16-server", and running sudo update-grub None of these work. It continues to load the first menuentry, which is "Ubuntu, with Linux 3.0.0-16-server". Below is my current /boot/grub/grub.cfg. What am I doing wrong? # # DO NOT EDIT THIS FILE # # It is automatically generated by grub-mkconfig using templates # from /etc/grub.d and settings from /etc/default/grub # ### BEGIN

  • Why you need to learn async in .NET

    - by PSteele
    I had an opportunity to teach a quick class yesterday about what’s new in .NET 4.0.  One of the topics was the TPL (Task Parallel Library) and how it can make async programming easier.  I also stressed that this is the direction Microsoft is going with for C# 5.0 and learning the TPL will greatly benefit their understanding of the new async stuff.  We had a little time left over and I was able to show some code that uses the Async CTP to accomplish some stuff, but it wasn’t a simple demo that you could jump in to and understand so I thought I’d thrown one together and put it in a blog post. The entire solution file with all of the sample projects is located here. A Simple Example Let’s start with a super-simple example (WindowsApplication01 in the solution). I’ve got a form that displays a label and a button.  When the user clicks the button, I want to start displaying the current time for 15 seconds and then stop. What I’d like to write is this: lblTime.ForeColor = Color.Red; for (var x = 0; x < 15; x++) { lblTime.Text = DateTime.Now.ToString("HH:mm:ss"); Thread.Sleep(1000); } lblTime.ForeColor = SystemColors.ControlText; (Note that I also changed the label’s color while counting – not quite an ILM-level effect, but it adds something to the demo!) As I’m sure most of my readers are aware, you can’t write WinForms code this way.  WinForms apps, by default, only have one thread running and it’s main job is to process messages from the windows message pump (for a more thorough explanation, see my Visual Studio Magazine article on multithreading in WinForms).  If you put a Thread.Sleep in the middle of that code, your UI will be locked up and unresponsive for those 15 seconds.  Not a good UX and something that needs to be fixed.  Sure, I could throw an “Application.DoEvents()” in there, but that’s hacky. The Windows Timer Then I think, “I can solve that.  I’ll use the Windows Timer to handle the timing in the background and simply notify me when the time has changed”.  Let’s see how I could accomplish this with a Windows timer (WindowsApplication02 in the solution): public partial class Form1 : Form { private readonly Timer clockTimer; private int counter;   public Form1() { InitializeComponent(); clockTimer = new Timer {Interval = 1000}; clockTimer.Tick += UpdateLabel; }   private void UpdateLabel(object sender, EventArgs e) { lblTime.Text = DateTime.Now.ToString("HH:mm:ss"); counter++; if (counter == 15) { clockTimer.Enabled = false; lblTime.ForeColor = SystemColors.ControlText; } }   private void cmdStart_Click(object sender, EventArgs e) { lblTime.ForeColor = Color.Red; counter = 0; clockTimer.Start(); } } Holy cow – things got pretty complicated here.  I use the timer to fire off a Tick event every second.  Inside there, I can update the label.  Granted, I can’t use a simple for/loop and have to maintain a global counter for the number of iterations.  And my “end” code (when the loop is finished) is now buried inside the bottom of the Tick event (inside an “if” statement).  I do, however, get a responsive application that doesn’t hang or stop repainting while the 15 seconds are ticking away. But doesn’t .NET have something that makes background processing easier? The BackgroundWorker Next I try .NET’s BackgroundWorker component – it’s specifically designed to do processing in a background thread (leaving the UI thread free to process the windows message pump) and allows updates to be performed on the main UI thread (WindowsApplication03 in the solution): public partial class Form1 : Form { private readonly BackgroundWorker worker;   public Form1() { InitializeComponent(); worker = new BackgroundWorker {WorkerReportsProgress = true}; worker.DoWork += StartUpdating; worker.ProgressChanged += UpdateLabel; worker.RunWorkerCompleted += ResetLabelColor; }   private void StartUpdating(object sender, DoWorkEventArgs e) { var workerObject = (BackgroundWorker) sender; for (int x = 0; x < 15; x++) { workerObject.ReportProgress(0); Thread.Sleep(1000); } }   private void UpdateLabel(object sender, ProgressChangedEventArgs e) { lblTime.Text = DateTime.Now.ToString("HH:mm:ss"); }   private void ResetLabelColor(object sender, RunWorkerCompletedEventArgs e) { lblTime.ForeColor = SystemColors.ControlText; }   private void cmdStart_Click(object sender, EventArgs e) { lblTime.ForeColor = Color.Red; worker.RunWorkerAsync(); } } Well, this got a little better (I think).  At least I now have my simple for/next loop back.  Unfortunately, I’m still dealing with event handlers spread throughout my code to co-ordinate all of this stuff in the right order. Time to look into the future. The async way Using the Async CTP, I can go back to much simpler code (WindowsApplication04 in the solution): private async void cmdStart_Click(object sender, EventArgs e) { lblTime.ForeColor = Color.Red; for (var x = 0; x < 15; x++) { lblTime.Text = DateTime.Now.ToString("HH:mm:ss"); await TaskEx.Delay(1000); } lblTime.ForeColor = SystemColors.ControlText; } This code will run just like the Timer or BackgroundWorker versions – fully responsive during the updates – yet is way easier to implement.  In fact, it’s almost a line-for-line copy of the original version of this code.  All of the async plumbing is handled by the compiler and the framework.  My code goes back to representing the “what” of what I want to do, not the “how”. I urge you to download the Async CTP.  All you need is .NET 4.0 and Visual Studio 2010 sp1 – no need to set up a virtual machine with the VS2011 beta (unless, of course, you want to dive right in to the C# 5.0 stuff!).  Starting playing around with this today and see how much easier it will be in the future to write async-enabled applications.

  • Sliding a div across to left and the next div appears

    - by littleMan
    I have this form Im creating and when you click on the "Next" button I want to slide the next form() across to the left this is my function jQuery('input[name^=Next]').click(function () { current.animate({ marginLeft: -current.width() }, 750); current = current.next(); }); That function isn't working the way I want to. it slides the text in the container across not the whole container it could be a css problem for all I know.

  • Why doesn't the highlighted part of the JavaScript work?

    - by Dor Cohen
    Why isn't the 'confirm password and password the same' part working? Meaning, the part that uses the 'getElementById' to adress the password and confirmpassword. Every part works but that particular part. It doesn't show a red box around the text fields. Can anyone help me? <html> <head> </head> <script> function submitinfo() { var firstname = document.getElementById("firstname").value; var lastname = document.getElementById("lastname").value; var username = document.getElementById("username").value; var password = document.getElementById("password").value; var confirmpassword = document.getElementById("confirmpassword").value; var email = document.getElementById("email").value; if(firstname !== "" && document.getElementById("firstname").style.borderColor == "red")     {     document.getElementById("firstname").style.border = "none"     } if(lastname !== "" && document.getElementById("lastname").style.borderColor == "red") { document.getElementById("lastname").style.border = "none" } if(username !== "" && document.getElementById("username").style.borderColor == "red") { document.getElementById("username").style.border = "none" } if(password !== "" && document.getElementById("password").style.borderColor == "red") { document.getElementById("password").style.border = "none" } if(confirmpassword !== "" && document.getElementById("confirmpassword").style.borderColor == "red") { document.getElementById("confirmpassword").style.border = "none" } if(email !== "" && document.getElementById("email").style.borderColor == "red") { document.getElementById("email").style.border = "none" } if(firstname == "") { document.getElementById("firstname").style.borderColor = "red"; document.getElementById("firstname").style.borderStyle = "solid"; } if(lastname == "") { document.getElementById("lastname").style.borderColor = "red"; document.getElementById("lastname").style.borderStyle = "solid"; } if(username == "") { document.getElementById("username").style.borderColor = "red"; document.getElementById("username").style.borderStyle = "solid"; } if(password == "") { document.getElementById("password").style.borderColor = "red"; document.getElementById("password").style.borderStyle = "solid"; } if(confirmpassword == "") { document.getElementById("confirmpassword").style.borderColor = "red"; document.getElementById("confirmpassword").style.borderStyle = "solid"; } if(email == "") { document.getElementById("email").style.borderColor = "red"; document.getElementById("email").style.borderStyle = "solid"; } if(password !== "" && confirmpassword !== "" && document.getElementById("password").style.border == "none" && document.getElementById("confirmpassword").style.border == "none" && password !== confirmpassword) { document.getElementById("password").style.border = "red"; document.getElementById("confirmpassword").style.border = "red"; } if(firstname && lastname && username && password && confirmpassword && email !== "") { window.open() } } </script> <h><font size=4 color=3BCCBE><b>Full Name</b></font><h/> <br> <input type="text" id="firstname" size="15px" placeholder="First"> <input type="text" id="lastname" size="15px" placeholder="Last"> <br> <br> <br> <br> <h><font size=4 color=3BCCBE><b>Choose your username</b></font></h> <br> <input type="text" id="username" size="37px"> <br> <p><font size=3 color="grey">atleast 6 characters long</font></p> <br> <h><font size=4 color=3BCCBE><b>Create a password</b></font></h> <br> <input type="password" id="password" size="37px"> <br> <br> <br> <br> <h><font size=4 color=3BCCBE><b>Confirm your password</b></font><h/> <br> <input type="password" id="confirmpassword" size="37px"> <br> <br> <br> <br> <h><font size=4 color=3BCCBE><b>Email address</b></font><h/> <br> <input type="text" id="email" size="37px"> <br> <br> <br> <br> <input type="button" value="Submit" onclick="submitinfo()" style="height:50px; width:85px; font-size:22px;> <br> </body> </html>

  • XML\Jquery create listings based on user selection

    - by Sirius Mane
    Alright, so what I need to try and accomplish is having a static web page that will display information pulled from an XML document and render it to the screen without refreshing. Basic AJAX stuff I guess. The trick is, as I'm trying to think this through I keep coming into 'logical' barriers mentally. Objectives: -Have a chart which displays baseball team names, wins, losses, ties. In my XML doc there is a 'pending' status, so games not completed should not be displayed.(Need help here) -Have a selection list which allows you to select a team which is populated from XML doc. (done) -Upon selecting a particular team from the aforementioned selection list the page should display in a separate area all of the planned games for that team. Including pending. Basically all of the games associated with that team and the dates (which is included in the XML file). (Need help here) What I have so far: HTML\JS <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <link rel="stylesheet" href="batty.css" type="text/css" /> <meta http-equiv="Content-Type" content="text/html;

$(xml).find('Teams').each(function(){ var title = $(this).find('Team').text(); select.append("<option/><option class='ddheader'>"+title+"</option>"); }); select.children(":first").text("please make a selection").attr("selected",true);

Any help right now would be great, I'm just banging my head against a wall. I'm trying to avoid using XSLT transforms because I absolutely despise XML and I'm not good with it. So I'd -like- to just use Javascript\PHP\etc with only a sprinkling of the necessary XML where possible..

  • Convience of mySQL over xml

    - by Bonechilla
    Currently I use XML to store specific information to correctly load a few things such as a list of specfied characters, scenes and music, Once more I use JAXB in combination with standard compression/decompression(ZIP) functionality to store a list of extrenous data. This data is called to add functionality to the character, somewhat like Skills in an RPG. Each skill is seperated into its own XML file with a grandlist which contains the names of each file with their extensions omitted and zipped in folder that gets encrypted. At first using xml was working fine however as the skill list grow i worry about its stability. I was wondering if I should begin storing the data in mySQL. Originally I planned to simply convert everything to JSON over xml but i think possibly mySQL would be a better move. Can anyone inform me of the key difference and pros and cons of each I guess i'm looking for the best way to store the data more conviently and would be easier to operate on. The data is mostly primatives and strings and the only arraylist of values i have i can just concat into a single field and parse later

  • Web Part to Update a List Data in SharePoint

    - by DanSogaard
    I'm trying to write a web part that access lists and add items in a specific list. The user modifies the web part and type in List Name, the web part has 3 TextBoxs and a Button. The user should enter data and press the save button, that should update the list and add these data in a new record. I'm using the following code to build my web part, but the save button doesn't update the list. I don't know what's wrong it just reload the page and add nothing. Edit: BTW the list am trying to update has three columns, First Name, Last Name, and Email, respectively. using System; using System.Web; using System.Web.UI.WebControls; using System.Web.UI.WebControls.WebParts; using System.Collections.Generic; using System.Text; using Microsoft.SharePoint; using Microsoft.SharePoint.Utilities; using Microsoft.SharePoint.WebControls; using Microsoft.SharePoint.WebPartPages; using Microsoft.SharePoint.Security; namespace TimeSheetEntry { public class TimesheetEntry : System.Web.UI.WebControls.WebParts.WebPart { public TimesheetEntry() { } protected TextBox txtFirstName; protected TextBox txtLastName; protected TextBox txtEmail; protected Button btnSave; protected string listName = string.Empty; [WebBrowsable(true), WebDisplayName("List Name"), WebDescription("Enter List Name"), Personalizable(PersonalizationScope.User)] public string LN { get { return this.listName; } set { this.listName = value; } } protected override void CreateChildControls() { //initialize textboxes txtFirstName = new TextBox(); txtLastName = new TextBox(); txtEmail = new TextBox(); //initialize button btnSave = new Button(); btnSave.Text = "Save"; btnSave.Click += new EventHandler(btnSave_Click); } protected override void Render(System.Web.UI.HtmlTextWriter writer) { writer.Write("<table width=100%>"); writer.Write("<tr>"); writer.Write("<td colspan=2>"); writer.Write("</td>"); writer.Write("</tr>"); writer.Write("<tr>"); writer.Write("<td>First:<span class=’ms-formvalidation’>*</span></td>"); writer.Write("<td>"); txtFirstName.RenderControl(writer); writer.Write("</td>"); writer.Write("</tr>"); writer.Write("<tr>"); writer.Write("<td>Last Name:<span class=’ms-formvalidation’>*</span></td>"); writer.Write("<td>"); txtLastName.RenderControl(writer); writer.Write("</td>"); writer.Write("</tr>"); writer.Write("<tr>"); writer.Write("<td>Email:<span class=’ms-formvalidation’>*</span></td>"); writer.Write("<td>"); txtEmail.RenderControl(writer); writer.Write("</td>"); writer.Write("</tr>"); writer.Write("<tr>"); writer.Write("<td>"); writer.Write("</td>"); writer.Write("<td>"); btnSave.RenderControl(writer); writer.Write("</td>"); writer.Write("</tr>"); writer.Write("</table>"); } public void btnSave_Click(object sender, EventArgs e) { SPWeb web = SPContext.Current.Web; SPList timesheetList = web.Lists[this.listName]; SPListItem newTimesheetEntry = timesheetList.Items.Add(); newTimesheetEntry["First Name"] = txtFirstName.Text; newTimesheetEntry["Last Name"] = txtLastName.Text; newTimesheetEntry["Email"] = txtEmail.Text; newTimesheetEntry.Update(); timesheetList.Update(); } } }
