  • .Net Entity objectcontext thread error

    - by Chris Klepeis
    I have an n-layered asp.net application which returns an object from my DAL to the BAL like so: public IEnumerable<SourceKey> Get(SourceKey sk) { var query = from SourceKey in _dataContext.SourceKeys select SourceKey; if (sk.sourceKey1 != null) { query = from SourceKey in query where SourceKey.sourceKey1 == sk.sourceKey1 select SourceKey; } return query.AsEnumerable(); } This result passes through my business layer and hits the UI layer to display to the end users. I do not lazy load to prevent query execution in other layers of my application. I created another function in my DAL to delete objects: public void Delete(SourceKey sk) { try { _dataContext.DeleteObject(sk); _dataContext.SaveChanges(); } catch (Exception ex) { Debug.WriteLine(ex.Message + " " + ex.StackTrace + " " + ex.InnerException); } } When I try to call "Delete" after calling the "Get" function, I receive this error: New transaction is not allowed because there are other threads running in the session This is an ASP.Net app. My DAL contains an entity data model. The class in which I have the above functions share the same _dataContext, which is instantiated in my constructor. My guess is that the reader is still open from the "Get" function and was not closed. How can I close it?

  • How should a programmer go about getting started with Flash/Flex/ActionScript?

    - by Graphics Noob
    What is the shortest path between zero (ie no flash related development software on my computer or information about where to obtain it or get started) to running a "hello world" ActionScript? I'm hoping for an answer that gives step by step instructions about exactly what software is needed to get started, an example of some "hello world" code, and instructions for compiling and running the code. I've spent more time than I think should be necessary researching this question and not found much information. Hopefully this question will be found by programmers like me who want to get started with Flash/Flex/ActionScript (After my morning of researching I still don't even know what terminology to use so I'll just throw it all out there). ActionScript tutorials I've found are focused on programming concepts, ie logic, branching, OOP, etc, and some even have code examples to download, but not a single one I've found explains how to compile and run the code. They all seem to assume you have an IDE standing by but no knowledge of programming, exactly the opposite of the position I'm in. Here are the most related SO questions I've found: http://stackoverflow.com/questions/59083/what-is-adobe-flex-is-it-just-flash-ii http://stackoverflow.com/questions/554899/getting-started-with-flex-3-ui-actionscript-programming http://stackoverflow.com/questions/2123105/how-to-learn-flex

  • JW Player playlist only loads randomly in IE, works fine in FF every time

    - by meow
    The playlist loads every time in FF but only the first time in IE (6-8), after that only randomly. If I alert the error that's thrown I get "TypeError: playerReady is undefined". My code looks good and obviously works since FF displays the playlist perfectly. I've got no idea how to solve this. Anyone? <script type='text/javascript'> var so = new SWFObject('/UI/Flash/player.swf', 'ply', '<%=FlashWidth %>', '<%=FlashHeight %>', '9', '#ffffff'), playlistURL = '<%=PlaylistURL %>', imageURL = '<%=GetBackgroundImageUrl() %>'; so.addParam('allowfullscreen', 'true'); so.addParam('allowscriptaccess', 'always'); if (playlistURL !== '') { so.addVariable('playlistfile', playlistURL); so.addVariable('playlist', 'none'); so.addVariable('enablejs', 'true'); } else { so.addVariable('file', '<%=FlashURL %>'); } if (imageURL.length > 0) { so.addVariable('image', imageURL); } so.write('preview<%=PlayerID %>'); </script>

  • Creating a REST client API using Reactive Extensions (Rx)

    - by Jonas Follesø
    I'm trying to get my head around the right use cases for Reactive Extensions (Rx). The examples that keeps coming up are UI events (drag and drop, drawing), and suggestions that Rx is suitable for asynchronous applications/operations such as web service calls. I'm working on an application where I need to write a tiny client API for a REST service. I need to call four REST end-points, three to get some reference data (Airports, Airlines, and Statuses), and the fourth is the main service that will give you flight times for a given airport. I have created classes exposing the three reference data services, and the methods look something like this: public Observable<Airport> GetAirports() public Observable<Airline> GetAirlines() public Observable<Status> GetStatuses() public Observable<Flights> GetFlights(string airport) In my GetFlights method I want each Flight to hold a reference the Airport it's departing from, and the Airline operating the flight. To do that I need the data from GetAirports and GetAirlines to be available. My initial thinking was something like this: Write a Rx Query that will Subscribe on the three reference services (Airports, Airlines and Statuses) Add results into a Dictionary (airline code and Airline object) When all three GetAirports, GetAirlines and GetStatuses are complete, then return the GetFlights IObservable. Is this a reasonable scenario for Rx? I'm developing on the Windows Phone 7, so I'm not sure if there are major differences in the Rx implementations across the different platforms.

  • I need a true mouseOver...

    - by invertedSpear
    Ok, so mouseOver and RollOver, and their respective outs work great as long as your mouse is actually over the item, or one of it's children. My problem is that I may have another UI component "between" my mouse and the item I want to process the mouse/rollover(maybe a button that is on top of a canvas, but is not a child of the canvas). The mouse is still over the component, there's just something else that it's over at the same time. Any tips or help how to deal with this? Let me know if I'm not being clear enough. Here is a simplified code example detailing my question copy/paste that into your flex/flash builder and you'll see what I mean: <?xml version="1.0" encoding="utf-8"?> <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" width="500" height="226" creationComplete="ccInit()"> <mx:Script> <![CDATA[ private function ccInit():void{ myCanv.addEventListener(MouseEvent.ROLL_OVER,handleRollOver); } private function handleRollOver(evt:MouseEvent):void{ myCanv.setStyle("backgroundAlpha",1); myCanv.addEventListener(MouseEvent.ROLL_OUT,handleRollOut); } private function handleRollOut(evt:MouseEvent):void{ myCanv.setStyle("backgroundAlpha",0); myCanv.removeEventListener(MouseEvent.ROLL_OUT,handleRollOut); } ]]> </mx:Script> <mx:Canvas id="myCanv" x="10" y="10" width="480" height="200" borderStyle="solid" borderColor="#000000" backgroundColor="#FFFFFF" backgroundAlpha="0"> </mx:Canvas> <mx:Button x="90" y="50" label="Button" width="327" height="100"/> </mx:Application>

  • Java problem with multiple threads when executing a runnable jar file

    - by Spi1988
    I have developed a Java Swing application, which uses the SwingWorker class to perform some long running tasks. When the application is run from the IDE (Netbeans), I can start multiple long running tasks simultaneously without any problem. I created a runnable jar file for the application, in order to be able to run it from outside the IDE. The application when run from this jar file works well with the only exception that it doesn't allow me to start 2 long running tasks simultaneously. When I start the first task (assume it takes 2 minitues to complete), every thing works fine, the UI does not freeze (it never freezes). However, when I try to run another task (assume it takes just 10 seconds, therefore it should finish before the first task) while the first task has not yet completed, nothing seems to happen. In reality, the second task would have started, and also finished its processing, however its results are only displayed once the first task completes. I dunno why this is happening. Is there some restriction on the number of threads which could run simultaneously on the JVM? Are there any jvm arguments which i could try to solve this problem. I hope i explained my problem well. Thanks in advance, Peter Bartolo

  • Explicit localization problem

    - by X-Dev
    when trying to translate the confirmation message to Norwegian i get the following error: Cannot have more than one binding on property 'OnClientClick' on 'System.Web.UI.WebControls.LinkButton'. Ensure that this property is not bound through an implicit expression, for example, using meta:resourcekey. i use Explicit localization in the following manner: <asp:LinkButton ID="lnkMarkInvoiced" runat="server" OnClick="lnkMarkInvoiced_OnClick" OnClientClick="<%# Resources: lnkMarkInvoicedResource.OnClientClick%>" Visible="False" CssClass="stdtext" meta:resourcekey="lnkMarkInvoicedResource" ></asp:LinkButton> here's the local resource file entry: <data name="lnkMarkInvoicedResource.OnClientClick" xml:space="preserve"> <value>return confirm('Er du sikker?');</value> if i remove the meta attribute i get the English text(default). how do i get the Norwegian text appearing without resorting to using the code behind? Update: removing the meta attribute prevents the exception from occurring but the original problem still exists. I can't get the Norwegian text to show. only the default English text shows. Another Update: I know this question is getting old but i still can't get the Norwegian text to display. If anyone has some tips please post a response.

  • SparkDataContainer Scroller not scrolling to bottom of container

    - by AZSL
    I am using a scroller component within a custom skin for a SkinnableDataContainer. I am running into an issue in that the thumbbar of the scroller stops at about the 50% point, however this is actually the end of the scrollable area. In actuality, the thumbbar should be at the bottom of the scroll track. Here's the code for the scroller: <s:SparkSkin xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark" xmlns:mx="library://ns.adobe.com/flex/halo" bottom="150" > <!-- Properties of the parent ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ --> <s:states> <s:State name="normal" /> <s:State name="disabled" /> </s:states> <!-- Metadata ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ --> <fx:Metadata> [HostComponent("spark.components.SkinnableDataContainer")] </fx:Metadata> <!-- UI components ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ --> <s:Rect left="0" right="0" bottom="0" top="0" radiusX="4" radiusY="4" > <s:fill> <s:SolidColor id="fillColor" color="0xEFEFEF"/> </s:fill> </s:Rect> <s:Group width="905" height="395" id="mainGroup"> <s:Scroller left="10" right="10" top="4" bottom="10" > <s:DataGroup id="dataGroup" /> </s:Scroller> <s:Rect left="0" right="0" top="0" bottom="0"> <s:stroke> <s:SolidColorStroke weight="1" color="0xD8D8D8"/> </s:stroke> </s:Rect> </s:Group>

  • Why does the following Toggle function perform four different operations instead of two?

    - by marcamillion
    You can see the implementation here: http://jsfiddle.net/BMWZd/8/ What I am trying to do, when you click on 'John Brown', you see the first element at top turn black. When you click it again, the border of the dotted circle disappears, then when you click 'John Brown' again, you see something else, then finally once again it all disappears. What I am trying to achieve is when you click it once, everything turns black (like it does now), then you click it again, everything disappears and goes back to the original state. Important distinction, what I mean is...when one of the names in the box are not clicked. So if you clicked John Brown then moved to Jack Dorsey, the #1 at top should stay black. But if you were to click Jack Dorsey again, i.e. you 'unclicked' it, then it should disappear. Also, how do I tighten it up, so that it responds quicker. Now when you click it, it feels like there is a little bit of a lag between when it was clicked and when it responds. Edit1: If anyone is interested...the UI that this will be used in is for my webapp - http://www.compversions.com

  • Possible defect with jQuery ':checked' selector (finding checked checkbox when there are none)

    - by Mphammad Ashour
    Found a strange thing. The following code is supposed to set a default value for a UI element based on whether one of a group of checkboxes (all having attribute name="privacy") is checked (in say, a form postback). If there is no value in the HTML sent by the server (the form is not a postback), the default value should be firstMenuItemKey. Otherwise, it should be the one checked in the underlying HTML. However, while this works on the first call to the URL that includes the form, a refresh of the page will set the value of defaultPrivacyValue to one of the privacy checkboxes'. I've checked that the server isn't checking the checkbox before the script runs (it's not). I've also checked whether somewhere else in the script is checking the checkbox (it's not). var defaultPrivacyValue = firstMenuItemKey; $('input[name=privacy]:checked').each(function() { defaultPrivacyValue = $(this).next().find('.name').text(); }); selectMenuItem(defaultPrivacyValue); When I chaged the selector to 'input[name=privacy][checked=checked]' it worked as expected. Is this a defect in the jQuery implementation of DOM retrieval based on the ':checked' selector???? I'm using jQuery 1.4.2. Thanks for any help you can give.

  • jquery child selector problems

    - by codedude
    I have a basic website nav layout that looks like this: <li class="folder parent_folder"> <a href="#">Some Folder</a> <ul class="submenu"> <li class="file"><a href="#">An awesome file</a></li> <li class="file"><a href="#">An awesome file</a></li> <li class="file"><a href="#">An awesome file</a></li> <li class="file"><a href="#">An awesome file</a></li> <li class="file"><a href="#">An awesome file</a></li> <li class="file"><a href="#">An awesome file</a></li> </ul> I have several of these throughout the site's page. Using jquery, I'm trying to make it so that when you click "li.parent_folder" "ul.submenu" disappears and then reappears when you click "li.parent_folder" again. I can get it to do this but I have a problem. When I click on the "li.parent_folder" all the "ul.submenu" disapear instead of just the one that is the child of it. What would be the correct jquery code to accomplish this? (Oh, I'm using jquery ui also in this project What I have right now is this: $('li.parent_folder').click(function() { $('li.parent_folder ul.submenu').hide(); });

  • Presenting an image cropping interface

    - by wkw
    I'm trying to engineer a UI for cropping images in iphone OS and suspect I'm going about things the hard way. My goal is pretty much what the Tapbots duo have done with Pastebot. In that app, they dim the source image but provide a movable and resizable cropping view and the image you're cropping is in a zoomable scrollview; when you resize or move the underlying image, the cropping view adjusts appropriately. I mocked up a composite image which will give a sense of the design I'm after, along with how I presently have my view hierarchy setup, viewable here The approach I've started with is the following: UIImageView with the image to crop is in a scrollview, a plain UIView with black fill and suitable transparency/alpha setting is added in front of the imageview. I then use a custom UIView which is a sibling to the scrollview at a higher level, which implements the drawRect: method and for the most part calls CGImageCreateWithImageInRect to get the portion of the image's bitmap that matches the position of the cropping view and draws that to the CGContext. in the viewcontroller I'm using the UIScrollViewDelegate methods to track scrolling and passing those changes to the custom cropping UIView so it stays in sync with the scroll contentOffset. That much is finally working. But trying to keep in sync as the scrollview zoomScale changes is when I figured I should ask for help. Looking for suggestions or guidance. My initial approach just seems like more work than is required. Could this be done with a masking layer in the ImageView? And if so, how would I setup the tracking for moving and resizing the cropping rect? My experience working with layers is non-nil, but very limited thus far.

  • Best way to test a Delphi application

    - by Osama ALASSIRY
    I have a Delphi application that has many dependencies, and it would be difficult to refactor it to use DUnit (it's huge), so I was thinking about using something like AutomatedQA's TestComplete to do the testing from the front-end UI. My main problem is that a bugfix or new feature sometimes breaks old code that was previously tested (manually), and used to work. I have setup the application to use command-line switches to open-up a specific form that could be tested, and I can create a set of values and clicks needed to be done. But I have a few questions before I do anything drastic... (and before purchasing anything) Is it worth it? Would this be a good way to test? The result of the test should in my database (Oracle), is there an easy way in testcomplete to check these values (multiple fields in multiple tables)? I would need to setup a test database to do all the automated testing, would there be an easy way to automate re-setting the test db? Other than drop user cascade, create user,..., impdp. Is there a way in testcomplete to specify command-line parameters for an exe? Does anybody have any similar experiences.

  • Qt/C++, Problems with large QImage

    - by David Günzel
    I'm pretty new to C++/Qt and I'm trying to create an application with Visual Studio C++ and Qt (4.8.3). The application displays images using a QGraphicsView, I need to change the images at pixel level. The basic code is (simplified): QImage* img = new QImage(img_width,img_height,QImage::Format_RGB32); while(do_some_stuff) { img->setPixel(x,y,color); } QGraphicsPixmapItem* pm = new QGraphicsPixmapItem(QPixmap::fromImage(*img)); QGraphicsScene* sc = new QGraphicsScene; sc->setSceneRect(0,0,img->width(),img->height()); sc->addItem(pm); ui.graphicsView->setScene(sc); This works well for images up to around 12000x6000 pixel. The weird thing happens beyond this size. When I set img_width=16000 and img_height=8000, for example, the line img = new QImage(...) returns a null image. The image data should be around 512,000,000 bytes, so it shouldn't be too large, even on a 32 bit system. Also, my machine (Win 7 64bit, 8 GB RAM) should be capable of holding the data. I've also tried this version: uchar* imgbuf = (uchar*) malloc(img_width*img_height*4); QImage* img = new QImage(imgbuf,img_width,img_height,QImage::Format_RGB32); At first, this works. The img pointer is valid and calling img-width() for example returns the correct image width (instead of 0, in case the image pointer is null). But as soon as I call img-setPixel(), the pointer becomes null and img-width() returns 0. So what am I doing wrong? Or is there a better way of modifying large images on pixel level? Regards, David

  • Any teams out there using TypeMock? Is it worth the hefty price tag?

    - by dferraro
    Hi, I hope this question is not 'controversial' - I'm just basically asking - has anyone here purchased TypeMock and been happy (or unhappy) with the results? We are a small dev shop of only 12 developers including the 2 dev managers. We've been using NMock so far but there are limitations. I have done research and started playing with TypeMock and I love it. It's super clean syntax and lets you basically mock everything, which is great for legacy code. The problem is - how do I justify to my boss spending 800-1200$ per license for an API which has 4-5 competitors that are completly free? 800-1200$ is how much Infragistrics or Telerik cost per license - and there sure as hell isn't 4-5 open source comparable UI frameworks... Which is why I find it a bit overpriced, albeit an awesome library... Any opinions / experiences are greatly appreciated. EDIT: after finding MOQ I thought I fell in love - until I found out that it's not fully supported in VB.NET because VB lacks lambda sub routines =(. Is anyone using MOQ for VB.NET? The problem is we are a mixed shop - we use C# for our CRM development and VB for everything else. Any guidence is greatly appreciated again

  • How do I pass parameters between request-scoped beans

    - by smayers81
    This is a question that has been bothering me for sometime. My application uses ICEFaces for our UI framework and Spring 2.5 for Dependency Injection. In addition, Spring actually maintains all of our backing beans, not the ICEFaces framework, so our faces-config is basically empty. Navigation is not even really handled through navigation-rules. We perform manual redirects to new windows using window.open. All of our beans are defined in our appContext file as being request-scoped. I have Page ABC which is backed by BackingBeanABC. Inside that backing bean, I have a parameter say: private Order order; I then have Page XYZ backed by BackingBeanXYZ. When I redirect from page ABC to page XYZ, I want to transfer the 'order' property from ABC to XYZ. The problem is since everything is request-scoped and I'm performing a redirect, I am losing the value of 'description'. There has got to be an easier way to pass objects between beans in request scope during a redirect. Can anyone assist with this issue?

  • After rich:extendedDataTable sortby,otheractions are not getting executed

    - by user118802
    I have a RichFaces UI which are having sidebar menu and sidebar had 8 links. I am using Seam @DataModel and @Factory and hibernate criteria to populate all the 8 pages. In all the pages i have sortby functionality which is working fine. I am able to get all data in all the 8 pages and I can freely navigate around all the links/xhtmls. But if in one of the xhtmlpages if I do sorting or groupby after that I am unable to navigate to other pages.If I select any other link the same last query which is executed for sorting is getting executed. Is this an issue? or do I need add any configuration. Please help me in solving this issue.

  • InfoPath FormControl on STA worker thread

    - by Rob Ford
    I have a .NET class that exposes two public methods: one to create an InfoPath form and another to Export to one of the supported formats. I’m using the Microsoft FormControl to do this. It’s hosted by a Form that does not get displayed. I get called by a Winforms app, but on an MTA worker thread instead of the UI thread. So I create an STA thread and execute on that, which works exactly once and then results in this exception: System.InvalidOperationException was unhandled Message="Unable to get the window handle for the 'FormControl' control. Windowless ActiveX controls are not supported." Source="System.Windows.Forms" StackTrace: at System.Windows.Forms.AxHost.EnsureWindowPresent() at System.Windows.Forms.AxHost.InPlaceActivate() at System.Windows.Forms.AxHost.TransitionUpTo(Int32 state) at System.Windows.Forms.AxHost.CreateHandle() at System.Windows.Forms.Control.CreateControl(Boolean fIgnoreVisible) at System.Windows.Forms.Control.CreateControl(Boolean fIgnoreVisible) at System.Windows.Forms.AxHost.EndInit() at InfoPathCreateStaThreadTest.FormControlHost.InitializeComponent() in C:\Windows\Temp\InfoPathCreateStaThreadTest\InfoPathCreateStaThreadTest\FormControlHost.Designer.cs:line 65 After some experimenting, I started to suspect this is a message pumping problem. I then came across this, which makes me more strongly suspect so: http://blogs.msdn.com/cbrumme/archive/2004/02/02/66219.aspx I tried various methods of pumping messages with no luck. I should mention that the alternative of automating the InfoPath app is not viable unless I can figure out how to hide the app. Any help would be much appreciated.

  • Windows Mobile : How to bind dropdown's selectedvalue to a column in table A and the list data to a

    - by Rob
    Hi, I am trying to learn the basics of Windows Mobile development against SQL CE and have come across a basic problem. I have two tables. One called Customers that stores customer info and has an identity column called ID as the primary key. The other table is called Orders which has a column called CustomerID (the FK constraint is present). I have added a DataSet to the project that contains both tables and have autogenerated the edit/view forms. This has produced a text control for the CustomerID column in the Order table for the new/edit form and I deleted it and replaced it with a dropdown list. Then, using the 'Advanced' databinding options (in Properties) I set the datasource of the list to the Customers table setting the value to the ID field and the text to the CustomerName field. I then set the SelectedValue of the list box to the CustomerID field of the Orders dataset. So far so good. When I run the app in the emulator and view the 'New' form for Orders the Customer dropdown is indeed populated with a list of customer names and I can select one and happily create a new order successfully. This is confirmed when I see the order appear in the Orders Grid form. However, when I then click on the order in the grid and then select 'Edit' the order loads but the dropdown always shows the first customer in the list and doesn't seem to bind the SelectedValue to the Orders dataset CustomerID field. Now I am an ASP.NET guy and normally hand craft the DAL and it's binding to the UI so I'm not entirely sure where to look to investigate what is going wrong here as this is all generated code. I am sure it is something very trivial but any pointers would be appreciated. My gut feeling is that the SelectedValue and the Customers.CustomerID values do not match for some reason? Many thanks, Rob.

  • Same route nested in multiple resources ember.js

    - by Daniel Upton
    I'm building an ember.js app which has a model called "Programme". A user can drill down to a programme by going: Genre > Subgenre > Programme or Folder > List > Programme Here's my router: this.resource('mylists', { path: '/' }, function() { this.resource('folder', { path: '/folder/:folder_id' }, function() { this.resource('list', { path: '/list/:list_id' }, function() { this.resource('programme', { path: '/programme/:programme_id' }); }); }); }); this.resource('catalogue', function() { this.resource('genre', { path: '/genre/:genre_id' }, function() { this.resource('subgenre', { path: '/subgenre/:subgenre_id' }, function() { this.resource('programme', { path: '/programme/:programme_id' }); }); }); }); The UI needs to be deeply nested (the genre view renders in the outlet of the catalogue template, the subgenre in the outlet of the genre template... and so forth). The problem I have is as both generated routes are called ProgrammeRoute when I linkTo the programme route inside the list template, it actually goes to the programme route nested in the subgenre route. What should I be doing here? To work around it I've named one route ListProgrammeRoute and SubgenreProgrammeRoute but that leads to some duplication.

    I had a lot of trouble installing Eclipse and PDT on my system. It took two days, largely because all the tutorials I could find were out of date (written in 2008, it's 2010 now) and various steps they included were no longer necessary, broken, or irrelevant. I wanted to write my process here so it could be improved upon (via wiki) as time goes on. Install Eclipse without PHP plugin ("Eclipse Classic"). This will give you a complete Eclipse, which I find preferable, as the UI is more fleshed out (e.g. you get a default list of Perspectives, which helps you understand what Perspectives are.) Install PDT SDK with the Help Install New Software menu item. You'd think you'd be done here, but if you try to run something, it'll fail complaining of not having a debugger. Install the Zend Debugger. It'll fail if you try to use the Install New Software option, as many tutorials suggest ("No repository found containing osgi.bundle.org.zend.php.debug.debugger.5.3.7.v20091116".) Instead, download it from http://www.zend.com/en/community/pdt, and manually copy the features/ and plugins/ directory into your Eclipse install (these instructions are not written anywhere). Restart Eclipse Monkey with preferences for a while -- if you followed a previous tutorial and tried to manually add your php executable to Eclipse prefs (/usr/bin/php), remove it (PHP PHP Executables). Set one of the Zend Debugger executables to the default. If you've already tried to execute a .php file, remove the existing "Run" profile you (maybe weren't aware that you) created (Run Debug Configurations...). Eclipse works! You should be able to run a .php file as a script just fine.

  • Display new image on web page

    - by RuiT
    Hello, I'm uploading images to a folder and I want to display each new image on a web page every time it is saved in the folder. I can display the initial image, which is already in the folder, and I can also detect when a new image is saved into the folder but I don't know how to display the new images. I'm new to web development. Can somebody help me? Here's the code: public partial class _Default : System.Web.UI.Page { string DirectoryPath = "C:\\Users\\Desktop\\PhotoUpload\\Uploads\\"; protected void Page_Load(object sender, EventArgs e) { FileSystemWatcher watcher = new FileSystemWatcher(); try { watcher.Path = DirectoryPath; watcher.Created += new FileSystemEventHandler(watcher_Created); watcher.EnableRaisingEvents = true; Image image = Image.FromFile(DirectoryPath + "inicial.jpg"); MemoryStream ms = new MemoryStream(); image.Save(ms, System.Drawing.Imaging.ImageFormat.Jpeg); byte[] im = ms.ToArray(); Context.Response.ContentType = "Image/JPG"; Context.Response.BinaryWrite(im); } catch (Exception ex) { } } void watcher_Created(object sender, FileSystemEventArgs e) { Console.WriteLine("File Created: Name: " + e.Name); try { //How to display new image? } catch (Exception ex) { } } }

  • How to draw some lines in a view element defined in the xml layout

    - by Nils
    Hello, I have problems drawing some simple lines in a view object (Android programming). First I created the layout with the view element(kind of painting area) in it (XML file). [...] < View android:id="@+id/viewmap" android:layout_width="572px" android:layout_height="359px" android:layout_x="26px" android:layout_y="27px" [...] ... and tried then to access it to draw some lines. Unfortunately the program is running and other UI elements like buttons are displayed, but I can't see the drawings. What's wrong ? [...] viewmap = (View) findViewById(R.id.viewmap); Canvas canvas = new Canvas(); viewmap.draw(canvas); Paint p = new Paint(); p.setColor(Color.BLUE); p.setStyle(Paint.Style.STROKE); canvas.drawColor(Color.WHITE); p.setColor(Color.BLUE); canvas.drawLine(4, 4, 29, 5, p); p.setColor(Color.RED); viewmap.draw(canvas); [...] Thanks for help :) !

  • equality on the sender of an event

    - by Berryl
    I have an interface for a UI widget, two of which are attributes of a presenter. public IMatrixWidget NonProjectActivityMatrix { set { // validate the incoming value and set the field _nonProjectActivityMatrix = value; .... // configure & load non-project activities } public IMatrixWidget ProjectActivityMatrix { set { // validate the incoming value and set the field _projectActivityMatrix = value; .... // configure & load project activities } The widget has an event that both presenter objects subscribe to, and so there is an event handler in the presenter like so: public void OnActivityEntry(object sender, EntryChangedEventArgs e) { // calculate newTotal here .... if (ReferenceEquals(sender, _nonProjectActivityMatrix)) { _nonProjectActivityMatrix.UpdateTotalHours(feedback.ActivityTotal); } else if (ReferenceEquals(sender, _projectActivityMatrix)) { _projectActivityMatrix.UpdateTotalHours(feedback.ActivityTotal); } else { // ERROR - we should never be here } } The problem is that the ReferenceEquals on the sender fails, even though it is the implemented widget that is the sender - the same implemented widget that was set to the presenter attribute! Can anyone spot what the problem / fix is? Cheers, Berryl I didn't know you could edit nicely. Cool. Here is the event raising code: void OnGridViewNumericUpDownEditingControl_ValueChanged(object sender, EventArgs e) { // omitted to save sapce if (EntryChanged == null) return; var args = new EntryChangedEventArgs(activityID, dayID, Convert.ToDouble(amount)); EntryChanged(this, args); } Here is the debugger dump of the presenter attribute, sans namespace info: ?_nonProjectActivityMatrix {WinPresentation.Widgets.MatrixWidgetDgv} [WinPresentation.Widgets.MatrixWidgetDgv]: {WinPresentation.Widgets.MatrixWidgetDgv} Here is the debugger dump of the sender: ?sender {WinPresentation.Widgets.MatrixWidgetDgv} base {Core.GUI.Widgets.Lookup.MatrixWidgetBase<Core.GUI.Widgets.Lookup.DynamicDisplayDto>}: {WinPresentation.Widgets.MatrixWidgetDgv} _configuration: {Domain.Presentation.Timesheet.Matrix.WeeklyMatrixConfiguration} _wrappedWidget: {Win.Widgets.DataGridViewDynamicLookupWidget} AllowUserToAddRows: true ColumnCount: 11 Count: 4 EntryChanged: {Method = {Void OnActivityEntry(System.Object, Smack.ConstructionAdmin.Domain.Presentation.Timesheet.Matrix.EntryChangedEventArgs)}} SelectedCell: {DataGridViewNumericUpDownCell { ColumnIndex=3, RowIndex=3 }} SelectedCellValue: "0.00" SelectedColumn: {DataGridViewNumericUpDownColumn { Name=MONDAY, Index=3 }} SelectedItem: {'AdministrativeActivity: 130-04', , AdministrativeTime, 0.00, 0.00, 0.00, 0.00, 0.00, 0.00, 0.00, 0.00} Berryl
