• updating batches of data

  - by gaponte69

  I am using GridView in asp .net and editing data with edit command field property (as we know after updating the edited row, we automatically update the database), and I want to use transactions (with begin to commit statement - including rollback) to commit this update query in database, after clicking in some button (after some events for example), not automatically to insert or update the edited data from grid directly to the DB...so I want to save them somewhere temporary (even many edited rows - not just one row) and then to confirm the transaction - to update the real tables in database... Any suggestions are welcomed... I've used some good links, but very helpful, like: http://www.asp.net/learn/data-access/tutorial-63-cs.aspx http://www.asp.net/learn/data-access/tutorial-66-cs.aspx etc...

• nHibernate one-to-many inserts but doesnt update

  - by user210713

  Instead of getting into code, I have a simple question. Default behavior for a simple one-to-many is that it inserts the child record then updates the foreign key column with the parent key. Has anyone ever had a one-to-many where the child object gets inserted but not updated resulting in a row in my table with a null in the foreign key column? I want the default behaviour for a standard one-to-many. I don't want to have to add the parent as a property to the child. Thanks.

• Android EditText and addTextChangedListener

  - by Alex

  im currently porting a database manager to android and due to performance reasons i like to update only propertys that have been modified. Im trying to do this with the addTextChangedListener in order to add modified entrys to a List, but my Program never enters any of its methods. EditText Et = (EditText) Editors.get(Prop.Name); Et.addTextChangedListener(new TextWatcher() { @Override public void afterTextChanged(Editable s) { // TODO Auto-generated method stub } @Override public void beforeTextChanged(CharSequence s, int start, int count, int after) { // TODO Auto-generated method stub } @Override public void onTextChanged(CharSequence s, int start, int before, int count) { // TODO Auto-generated method stub if(Prop.GetType() == Property.PROPTYPE.num) { float f = Float.parseFloat(s.toString()); Prop.FromString(f); } else { Prop.FromString(s.toString()); } propertiesToUpdate.add(Prop); }); Et.setText(Prop.ToString());

• Is there a way to catch a MOUSE_UP Event over a static textfield in Flash?

  - by Jovica Aleksic

  When the user presses the mouse, and releases it over a static textfield with selectable text, no MOUSE_UP event is fired - not on the stage and also nowhere else. I experienced this when using a scrollbar class on a movieclip with a nested static textfield. When the user drags the scroll handle and releases the mouse over the textfield, the dragging/scrolling is stuck. To test this, create a new AS3 fla file, place a static textfield somewhere, and put in some text. Make sure the selectable property is checked in the properties panel. Add this script to the timeline: import flash.events.* function down(event:Event):void { trace('down'); } function up(event:Event):void { trace('up'); } stage.addEventListener(MouseEvent.MOUSE_DOWN, down) stage.addEventListener(MouseEvent.MOUSE_UP, up) Now test the movie and click the mouse. You will notice that trace('up') will not occur when you release the mouse over the textfield.

• ItemsControl that loads items one by one asynchronously.

  - by Vinit Sankhe

  Hey Guys, I am creating a custom DataGrid by deriving the traditional tookit based WPF DataGrid. I want a functionality in the grid to load items one by one asynchronously, wherein as soon as ItemsSource is changed i.e. a new collection is Set to the ItemsSource property or the bound collection is Changed dues to items that rae added, moved or removed (wherein the notifications comes to the data grid when the underlying source implements INotifyCollectionChanged such as ObservableCollection). This is because even with virtualising stackpanel underneath the datagrid takes time to load (2-3 seconds delay) to load the data rows when it has several columns and some are template based. With above behavior that delay would "appear" to have reduced giving datagrid a feel that it has the data and is responsive enough to load it. How can I achieve it? Thx Vinit.

• Assembly.CodeBase: when is it no file-URI?

  - by Marc Wittke

  Assembly.Location gives a plain path to the assembly. Unfortunately this is empty when running in a shadowed environment, such as unit test or ASP.NET. Hovever, the Codebase property is available and provides a URI that can be used instead. In which cases it returns no URI starting with file:///? Or in other words: what are the cases in which this won't work or will return unusable results? Assembly assembly = GetType().Assembly; Uri codeBaseUri = new Uri(assembly.CodeBase); string path = codeBaseUri.LocalPath;

• Location tagging facebook open graph actions so that only friends in that location view in their feeds

  - by Arvind Srinivasan

  Is there a way to tag open graph actions so as to target certain recipients and not others? For example, if my app talks about new coffee shop openings in various cities, is there a way to publish the 'opening' action to the graph, perhaps with location / coordinates, such that this is only seen by friends in that locality? I really don't want to spam my friends in London about an opening I'm excited about in Portland. How can I help facebook with the feed relevance in these cases? I noticed that there is a "place" property on open graph objects - could this somehow be used?

• Rectangular BackColor of selection in RichTextBox

  - by AgentConundrum

  Background: I'm going to start studying/coding at the local university's library. Since I'm not a student, I won't be able to utilize their wireless internet access. Since StackOverflow is such a great resource, I want to be able to take it with me, so I'm building a small desktop application to load/search/display the most recent data dumps. Problem: I want to display code blocks in the same sort of rectangular block as this site does, so I played with the RichTextBox control to try to create this effect. Unfortunately, the RichTextBox.SelectedBackColor property only colors the actual text, when what I want is a rectangle reaching to the outer limits of the selection. Example: This is what I am able to produce with the RichTextBox: This is what I would like to create: Questions: Is there any way to produce this effect using the RichTextBox? If not, are there any other controls I could use to create this effect?

• C# implicit conversions

  - by Chris Boden

  Hello, I'm currently working on an application where I need to load data from an SQL database and then assign the retrieved values into the properties of an object. I'm doing this by using reflection since the property names and column names are the same. However, many of the properties are using a custom struct type that is basically a currency wrapper for the decimal type. I have defined an implicit conversion in my struct: public static implicit operator Currency(decimal d) { return new Currency(d); } This works fine when I use it in code. However, when I have this: foreach (PropertyInfo p in props) { p.SetValue(this, table.Rows[0][p.Name], null); } It throws an ArgumentException stating that it cannot convert from System.Decimal to Currency. I'm confused since it works fine in any other circumstance.

• TortoiseSVN shows red ! decorator for folder, but no files within it are marked with !

  - by Clay Nichols

  I'm new to SVN. I'm using the latest version (svn 1.6.9, TortoiseSVN 1.6.7.18415). Some folders who a red exclamation point next to them. If I drill down, I find a sub folder with ! as well but no files within that are marked with ! (all are either a green checkmark or no icon (because they are Ignored (like .exe files) . What I've tried: Cleanup {reported success} Add {reports nothing to add. All files either under version control has been ignored per the .ignore property. Commit {succeeds} SVNupdate {succeeds} Restarted computer. Some oddities: -I had a bunch of CVS folders (these files were copied over from a PC that was using CVS but we don't need that version history so I didn't import it into SVN). I deleted those CVS\ folders and they are showing up (as unversioned files) when I CheckIn. Any ideas?

• How change Subversion's default binary mime-type?

  - by lamcro

  Subversion sets a binary file's svn:mime-type property to application/octet-stream by default. I need to change this default to some other mime-type. When I import for the first time this code, I would like Subversion to set mime-type to the one I choose. The reason is that my code base contains code in binary files (proprietary format), and I have the applications necessary to emulate diff and diff3 for these. But Subversion does not let me due to their default mime-type. Please note: There is no default extension (*.jar, *.py, etc) for these code files. Some files don't even have an extension. So configuring mime-type by file extension is not possible.

• JQuery-tmpl Template Switching Not working.

  - by Mike

  I'm trying to implement "more/less" functionality using the official jquery-tmpl plugin. I've looked at the examples, but I cannot seem to get the functionality to work in my own implementation. When I click on one of my "More" buttons, I seem to get an error thrown of: Uncaught TypeError: Property 'tmpl' of object #<an Object> is not a function This is my implementation here From what I can tell, the example I'm trying to replace is doing the following: Render the "Master" template On-click: Find the corresponding template object (tmplItem) to the clicked element. Pass in reference to a new template. Call the update function to re-render. Have I understood the documentation wrong? From what I can tell I'm doing the same thing as the example on the official documentation.

• Managing multiple WCF endpoints for the same service

  - by Jacob

  I am building an single application that uses WCF to call out to multiple external endpoints. All of the remote endpoints are identical except for the URI. I would like to treat them as a pool: add and remove endpoints through configuration and have the application understand what to do. My original plan was to define one endoint in the app.config, then iterate over my list of endpoints and update client.Endpoint.Address on the fly to point to the right place. Unfortunately, that property is read-only, rendering that plan unworkable. I'm a little bit stumped here. Any suggestions on how I might accomplish this?

• Eclipse RCP Application Fails to launch second time

  - by ibuck

  I have an Eclipse RCP application that will launch properly after a clean install (right after build). The issue is that if I try to launch the application a second time the application throws an exception. I have narrowed the issue down to this file being created after the first run: ~install_dir/configuration/org.eclipse.osgi/.state Has anyone run into a similar issue where the .state file prevents the application from being launched anytime after that first run? I'm hesitant to look at the exception as this does not happen the first time, so I suspect org.eclipse.osgi is more to blame. The details of the exception are: "Error creating bean with name 'luceneRawQueryComposer' defined in class path resource [spring/dataaccess/daoCMClient.xml]: Cannot resolve reference to bean 'indexUtility' while setting bean property 'indexUtility'; NoSuchBeanDefinitionException

• Limit JavaScript and CSS files on ASP.NET MVC 2 Master Page based on Model and View content

  - by Zack Peterson

  I want to include certain .js and .css files only on pages that need them. For example, my EditorTemplate DateTime.ascx needs files anytimec.js and anytimec.css. That template is applied whenever I use either the EditorFor or EditorForModel helper methods in a view for a model with a DateTime type value. I've put this condition into the <head> section of my master page. It checks for a DateTime type property in the ModelMetadata. <% if (this.ViewData.ModelMetadata.Properties.Any(p => p.ModelType == typeof(DateTime))) { %> <link href="../../Content/anytimec.css" rel="stylesheet" type="text/css" /> <script src="../../Scripts/anytimec.js" type="text/javascript"></script> <% } %> This has two problems: Fails if I have nested child models of type DateTime Unnecessarily triggered by views without EditorFor or EditorForModel methods (example: DisplayForModel) How can I improve this technique?

• Iterate through a VB6 Dictionary

  - by Dinah

  I'm a non-VB6 person who had the misfortune of inheriting a buggy legacy VB6/Classic ASP project. There's a section where a lot of entries are put into a Dictionary and I want to see all it contains. I tried this (oParams is a Dictionary): Dim o As Object Dim sDicTempAggr As String sDicTempAggr = "" For Each o In oParams sDicTempAggr = sDicTempAggr & ", " & o Next Which returned: Object doesn't support this property or method : 438 Using Option Explicit, how do I iterate through a VB6 Dictionary to find out everything it contains?

• Combining SpecFlow table and Moq mocked object

  - by Confused

  I have a situation where I want to use a mocked object (using Moq) so I can create setup and expectations, but also want to supply some of the property values using the SpecFlow Table. Is there a convenient way to create a mock and supply the table for the seed values? // Specflow feature Scenario Outline: MyOutline Given I have a MyObject object as | Field | Value | | Title | The Title | | Id | The Id | // Specflow step code Mock<MyObject> _myMock; [Given(@"I have a MyObject object as")] public void GivenIHaveAMyObjectObjectAs(Table table) { var obj = table.CreateInstance<MyObject>(); _myMock = new Mock<MyObject>(); // How do I easily combine the two? }

• Save UITextView content in NSString.

  - by camilo

  Hi, I'm trying to save the contents of an UITextView into a NSString which I will somehow persist later. The problem is that the UITextView "text" property doesn't save all the rows in the textView (after touching "return"). I tried print the TextView object and the textView.text, and they're different. Does anybody know how (after editing the textView) I can save its content into a String (or something else that I can later access and share through different views and persist in the database)? Thanks a lot. Pretty sure it is simple, but I'm honestly not finding the solution.

• frequency of objects in an array using Ruby

  - by eastafri

  If i had a list of balls each of which has a color property. how can i cleanly get the list of balls with the most frequent color. [m1,m2,m3,m4] say, m1.color = blue m2.color = blue m3.color = red m4.color = blue [m1,m2,m4] is the list of balls with the most frequent color My Approach is to do: [m1,m2,m3,m4].group_by{|ball| ball.color}.each do |samecolor| my_items = samecolor.count end where count is defined as class Array def count k =Hash.new(0) self.each{|x|k[x]+=1} k end end my_items will be a hash of frequencies foreach same color group. My implementation could be buggy and i feel there must be a better and more smarter way. any ideas please?

• Ninject: Abstract Class

  Hello, Do I need to do something different in an abstract class to get dependency injection working with Ninject? I have a base controller with the following code: public abstract class BaseController : Controller { public IAccountRepository AccountRepository { get; set; } } My module looks like this: public class WebDependencyModule : NinjectModule { public override void Load() { Bind<IAccountRepository>().To<AccountRepository>(); } } And this is my Global.asax: protected override void OnApplicationStarted() { Kernel.Load(new WebDependencyModule()); } protected override IKernel CreateKernel() { return new StandardKernel(); } It works when I decorate the IAccountRepository property with the [Inject] attribute. Thanks in advance.

• NSDate & Memory management

  - by iFloh

  Hi, memory management still gives me grief. This time it is an NSDate iVar that I init using NSDate *myNSDate = [[NSDate date] firstDayOfMonth]; with a method call to - (NSDate *)firstDayOfMonth { NSDateComponents *tmpDateComponents = [[NSCalendar currentCalendar] components:NSYearCalendarUnit | NSMonthCalendarUnit | NSEraCalendarUnit | NSWeekCalendarUnit | NSWeekdayOrdinalCalendarUnit fromDate:self]; [tmpDateComponents setDay:1]; [tmpDateComponents setHour:0]; [tmpDateComponents setMinute:0]; [tmpDateComponents setSecond:0]; return [[NSCalendar currentCalendar] dateFromComponents:tmpDateComponents]; } At the end of the init call the retain count is at 1 (Note the iVar is not defined as a property). When I step into the viewWillAppear method the myNSDate has vanished. I tried to do an explicit retain on it, but that only lasts until I update the iVar using the above method again. I though - ok - I add the retain to the return of the function, but that makes the leak analyser throw up an error. What am I doing wrong?
