  • VB.net (aspx) mysql connection

    - by StealthRT
    Hey all i am new to ASP.NET and VB.net code behind. I have a classic ASP page that connects to the mySQL server with the following code: Set oConnection = Server.CreateObject("ADODB.Connection") Set oRecordset = Server.CreateObject("ADODB.Recordset") oConnection.Open "DRIVER={MySQL ODBC 3.51 Driver}; SERVER=xxx.com; PORT=3306; DATABASE=xxx; USER=xxx; PASSWORD=xxx; OPTION=3;" sqltemp = "select * from userinfo WHERE emailAddress = '" & theUN & "'" oRecordset.Open sqltemp, oConnection,3,3 if oRecordset.EOF then ... However, i am unable to find anything to connect to mySQL in ASP.NET (VB.NET). I have only found this peice of code that does not seem to work once it gets to the "Dim conn As New OdbcConnection(MyConString)" code: Dim MyConString As String = "DRIVER={MySQL ODBC 3.51 Driver};" & _ "SERVER=xxx.com;" & _ "DATABASE=xxx;" & _ "UID=xxx;" & _ "PASSWORD=xxx;" & _ "OPTION=3;" Dim conn As New OdbcConnection(MyConString) MyConnection.Open() Dim MyCommand As New OdbcCommand MyCommand.Connection = MyConnection MyCommand.CommandText = "select * from userinfo WHERE emailAddress = '" & theUN & "'"" MyCommand.ExecuteNonQuery() MyConnection.Close() I have these import statements also: <%@ Import Namespace=System %> <%@ Import Namespace=System.IO %> <%@ Import Namespace=System.Web %> <%@ Import Namespace=System.ServiceProcess %> <%@ Import Namespace=Microsoft.Data.Odbc %> <%@ Import Namespace=MySql.Data.MySqlClient %> <%@ Import Namespace=MySql.Data %> <%@ Import Namespace=System.Data %> So any help would be great! :o) David

  • C#: WebBrowser.Navigated Only Fires when I MessageBox.Show();

    - by tsilb
    I have a WebBrowser control which is being instantiated dynamically from a background STA thread because the parent thread is a BackgroundWorker and has lots of other things to do. The problem is that the Navigated event never fires, unless I pop a MessageBox.Show() in the method that told it to .Navigate(). I shall explain: ThreadStart ts = new ThreadStart(GetLandingPageContent_ChildThread); Thread t = new Thread(ts); t.SetApartmentState(ApartmentState.STA); t.Name = "Mailbox Processor"; t.Start(); protected void GetLandingPageContent_ChildThread() { WebBrowser wb = new WebBrowser(); wb.Navigated += new WebBrowserNavigatedEventHandler(wb_Navigated); wb.Navigate(_url); MessageBox.Show("W00t"); } protected void wb_Navigated(object sender, WebBrowserNavigatedEventArgs e) { WebBrowser wb = (WebBrowser)sender; // Breakpoint HtmlDocument hDoc = wb.Document; } This works fine; but the messagebox will get in the way since this is an automation app. When I remove the MessageBox.Show(), the WebBrowser.Navigated event never fires. I've tried supplanting this line with a Thread.Sleep(), and by suspending the parent thread. Once I get this out of the way, I intend to Suspend the parent thread while the WebBrowser is doing its job and find some way of passing the resulting HTML back to the parent thread so it can continue with further logic. Why does it do this? How can I fix it? If someone can provide me with a way to fetch the content of a web page, fill out some data, and return the content of the page on the other side of the submit button, all against a webserver that doesn't support POST verbs nor passing data via QueryString, I'll also accept that answer as this whole exercise will have been unneccessary.

  • What's the proper way to setup different objects as delegates using Interface Builder?

    - by eagle
    Let's say I create a new project. I now add two text fields to the view controller in Interface Builder. I want to respond to delegate events that the text fields create, however, I don't want to have the main view controller to act as the delegate for both text fields. Ideally I want a separate file for each text field that acts as the delegate. Each of these objects also needs to be able to interact with the main view controller. My question is how I would set this up and link everything correctly? I tried creating a new class that inherits from NSObject and implements UITextFieldDelegate. I then added an instance variable called "viewController" of the same type of my view controller and marked it with IBOutlet (this required me to add #import "myViewcontroller.h"). I then went to Interface Builder and opened up my view controller which contains the two edit boxes. I added an NSObject to the form and changed it's type to be of the new class I created. I set its viewController property to the File's Owner, and set one of the textbox's delegate properties to point to this new object I created. Now when I run the program, it crashes when I touch the text box. It gives the error EXC_BAD_ACCESS. I'm guessing I didn't link stuff correctly in IB. Some things I'm not sure about which might be the problem: Does IB automatically know to create an instance of the class just by placing the NSObject in the ViewController? Can it properly assign the viewController property to an instance of itself even though it is creating itself at the same time?

  • Simple Android Binary Text Clock

    - by Hristo
    Hello, I want to create a simple android binary clock but my application crashes. I use 6 textview fields: 3 for the decimal and 3 for the binary representation of the current time (HH:mm:ss).

  • ThreadAbortException (WebClient using DownloadFile to grab file from server)

    - by baron
    Hi Everyone, Referencing my Earlier Question, regarding downloading a file from a server and handling exceptions properly. I am positive that I had this solved, then in classic programming fashion, returned days later to frustratingly find it broken :-( Updated code: private static void GoGetIt(HttpContext context) { var directoryInfoOfWhereTheDirectoryFullOfFilesShouldBe = new FileInfo(......); var name = SomeBasicLogicToDecideName(); //if (!directoryInfoOfWhereTheDirectoryFullOfFilesShouldBe.RefreshExists()) //{ // throw new Exception(string.Format("Could not find {0}.", name)); //} var tempDirectory = ""; //Omitted - creates temporary directory try { directoryInfoOfWhereTheDirectoryFullOfFilesShouldBe.CopyAll(tempDirectory); var response = context.Response; response.ContentType = "binary/octet-stream"; response.AddHeader("Content-Disposition", string.Format("attachment;filename={0}.zip", name)); ZipHelper.ZipDirectoryToStream(tempDirectory, response.OutputStream); response.End(); } catch (Exception ex) { Debug.WriteLine(ex.ToString()); context.Response.StatusCode = 404; } finally { tempDirectory.DeleteWithPrejudice(); } } This was working fine, and returning the zip, otherwise if the file didn't exist returning 404. Then on the client side I could handle this: public bool Download() { try { using (var client = new WebClient()) { client.DownloadFile(name, tempFilePath); } } catch (Exception) { fileExists = false; } return fileExists; } But the problem now is two things. 1) I get System.Threading.ThreadAbortException: Thread was being aborted in the server side try-catch block. Usually this was just a file not found exception. I have no idea what or why that new exception is throwing? 2) Now that a different exception is throwing on the server side instead of the file not found, it would seem I can't use this set up for the application, because back on client side, any exception is assumed to be filenotfound. Any help, especially info on why this ThreadAbortException is throwing!?!? greatly appreciated. Cheers

  • ASP.NET Projects with Two Versions of AjaxControlToolkit

    - by Chris
    In my Solution I have three projects. Project A is a web app and uses version 1.0.10618.0 of the AjaxControlToolkit. I would love to upgrade it to the latest but unfortunately any newer release completely breaks a portion of my site. Project B is also a web app but is a completely new software product and so it uses (and relies on) the latest version of the AjaxControlToolkit. Everything works great. Thought A and B are totally different products they use the same DB and rely on the same ClassLibrary. Project C is a small web app that ties A and B together with certain functionality like forgot password pages. The pages in this app reside in a virtual directory of both A and B. Project C currently uses v1.0.10618.0 of the toolkit so it works with Project A but it fails with project B because the manifest definitions of the dlls don't match (to be expected). What I've done is built a new dll of the toolkit and changed the assembly and namespace to AjaxControlToolkit_v1 and then changed all v1 references to this new dll so the old version and new versions can sit side by side in the same bin folder and nobody complains. I then changed my web.config controls tag to look like this: <add tagPrefix="ajaxToolkit" namespace="AjaxControlToolkit_v1" assembly="AjaxControlToolkit_v1, Version=1.0.10618.0, Culture=neutral, PublicKeyToken=28f01b0e84b6d53e"/> This all works except I get a runtime error of: Unknown server tag 'ajaxToolkit:AnimationExtender'. I can't figure out why this is, any ideas on how to remedy it?

  • Using Java Executor on AppEngine causes AccessControlException

    - by Drew
    How do you get java.util.concurrent.Executor or CompletionService to work on Google AppEngine? The classes are all officially white-listed, but I get a runtime security error when trying to submit asynchronous tasks. Code: // uses the async API but this factory makes it so that tasks really // happen sequentially Executor executor = java.util.concurrent.Executors.newSingleThreadExecutor(); // wrap Executor in CompletionService CompletionService<String> completionService = new ExecutorCompletionService<String>(executor); final SomeTask someTask = new SomeTask(); // this line throws exception completionService.submit(new Callable<String>(){ public String call() { return someTask.doNothing("blah"); } }); // alternately, send Runnable task directly to Executor, // which also throws an exception executor.execute(new Runnable(){ public void run() { someTask.doNothing("blah"); } }); } private class SomeTask{ public String doNothing(String message){ return message; } } Exception: java.security.AccessControlException: access denied (java.lang.RuntimePermission modifyThreadGroup) at java.security.AccessControlContext.checkPermission(AccessControlContext.java:323) at java.security.AccessController.checkPermission(AccessController.java:546) at java.lang.SecurityManager.checkPermission(SecurityManager.java:532) at com.google.appengine.tools.development.DevAppServerFactory$CustomSecurityManager.checkPermission(DevAppServerFactory.java:166) at com.google.appengine.tools.development.DevAppServerFactory$CustomSecurityManager.checkAccess(DevAppServerFactory.java:191) at java.lang.ThreadGroup.checkAccess(ThreadGroup.java:288) at java.lang.Thread.init(Thread.java:332) at java.lang.Thread.(Thread.java:565) at java.util.concurrent.Executors$DefaultThreadFactory.newThread(Executors.java:542) at java.util.concurrent.ThreadPoolExecutor.addThread(ThreadPoolExecutor.java:672) at java.util.concurrent.ThreadPoolExecutor.addIfUnderCorePoolSize(ThreadPoolExecutor.java:697) at java.util.concurrent.ThreadPoolExecutor.execute(ThreadPoolExecutor.java:652) at java.util.concurrent.Executors$DelegatedExecutorService.execute(Executors.java:590) at java.util.concurrent.ExecutorCompletionService.submit(ExecutorCompletionService.java:152) This code works fine when run on Tomcat or via command-line JVM. However, it chokes in the AppEngine SDK Jetty container (tried with Eclipse plugin and the maven-gae-plugin). AppEngine is likely designed to not allow potentially dangerous programs to run, so I could see them completely disabling thread creation. However, why would Google allow you to create a class, but not allow you to call methods on it? White-listing java.util.concurrent is misleading. Is there some other way to do parallel/simultaneous/concurrent tasks on GAE?

  • WCF RIA Silverlight deployment issues

    - by Handleman
    It seems the world is awash with people having problems deploying RIA WCF services, and now I'm one too. I've already tried a bunch of things, but to no avail. I need WCF RIA to support a Silverlight 3 application I've built. The short story is, using the new WCF RIA services (Nov 09?) I open VS 2008, create new project (silverlight application), enabling ".NET RIA services". Add new item to web project - Linq2SQL dbml file (from SQL 2005 DB prepared earlier) and compile. I add a new item to the web project - domain service (link the tables I need) and compiled. Using the domain context I "Load" data with a standard RIA get query in the MainPage and add a TextBlock to display returned data. Build & run (cassini) - success. Using VS to publish to IIS on local PC - success. Using VS to publish to test server (IIS6) - browse to location and the Silverlight app loads but Fiddler tells me I've got a 404 on all the the WCF .svc requests. Use Fiddler to "launch IE" on the service request and it's true - 404. I have already run aspnet_regiis, ServiceModelReg and added mime types for .xap, .xaml, .xbap and .svc. I have included the System.Web.Ria and System.Web.DomainServices DLL with copy local true. I need help with either a) a solution b) an approach to find a solution

  • OleDb database to DataSet and back in c#?

    - by Troy
    I'm writing a program that lets a user: Connect to an (arbitrary) View all of the tables in that database in separate DataGridViews Edit them in the program, generate random data, and see the results Choose to commit those changes or revert So I discovered the DataSet class, which looks like it's capable of holding everything that a database would, and I decided that the best thing to do here would be to load everything into one dataset, let the user edit it, and then save the dataset back to the database. The problem is that the only way I can find to load the database tables is this: set = new DataSet(); DataTable schema = connection.GetOleDbSchemaTable( OleDbSchemaGuid.Tables, new string[] { null, null, null, "TABLE" }); foreach (DataRow row in schema.Rows) { string tableName = row.Field<string>("TABLE_NAME"); DataTable dTable = new DataTable(); new OleDbDataAdapter("SELECT * FROM " + tableName, connection).Fill(dTable); dTable.TableName = tableName; set.Tables.Add(dTable); } while it seems like there should be a simpler way given that datasets appear to be designed for exactly this purpose. The real problem though is when I try saving these things. In order to use the OleDbDataAdapter.Update() method, I'm told that I have to provide valid INSERT queries. Doesn't that kind of negate the whole point of having a class to handle this stuff for me? Anyway, I'm hoping somebody can either explain how to load and save a database into a dataset or maybe give me a better idea of how to do what I'm trying to do. I could always parse the commands together myself, but that doesn't seem like the best solution.

  • Bring Winforms control to front

    - by Nathan
    Are there any other methods of bringing a control to the front other than control.BringToFront()? I have series of labels on a user control and when I try to bring one of them to front it is not working. I have even looped through all the controls and sent them all the back except for the one I am interested in and it doesn't change a thing. Here is the method where a label is added to the user control private void AddUserLabel() { UserLabel field = new UserLabel(); ++fieldNumber; field.Name = "field" + fieldNumber.ToString(); field.Top = field.FieldTop + fieldNumber; field.Left = field.FieldLeft + fieldNumber; field.Height = field.FieldHeight; field.Width = field.FieldWidth; field.RotationAngle = field.FieldRotation; field.Barcode = field.BarCoded; field.HumanReadable = field.HumanReadable; field.Text = field.FieldText; field.ForeColor = Color.Black; field.MouseDown += new MouseEventHandler(label_MouseDown); field.MouseUp += new MouseEventHandler(label_MouseUp); field.MouseMove += new MouseEventHandler(label_MouseMove); userContainer.Controls.Add(field); SendLabelsToBack(); //Send All labels to back userContainer.Controls[field.FieldName].BringToFront(); } Here is the method that sends all of them to the back. private void SendLabelsToBack() { foreach (UserLabel lbl in userContainer.Controls) { lbl.SendToBack(); } }

  • ez components and AWS PHP SDK makes ez components freak out

    - by David
    Hi, I try to work with ez Components and AWS PHP SDK at the same time. I have a file called resize.php which is just handling resizing images using the ez Components ImageTransition tools. I queue the image for resize in Amazon AWS SQS. If I load the AWS PHP SDK and ez Components in the same file, PHP always complains about not finding the ez Components classes. Code looks something like this: amazonSQS.php: require 'modules/resize.php'; require 'modules/aws/sdk.class.php'; $sqs = new AmazonSQS(); $response = $sqs->send_message($queue_url, $message); resize.php: function resize_image($filename) { $settings = new ezcImageConverterSettings( array( //new ezcImageHandlerSettings( 'GD', 'ezcImageGdHandler' ), new ezcImageHandlerSettings( 'ImageMagick', 'ezcImageImagemagickHandler' ), ) ); Error message: Fatal error: Class 'ezcImageConverterSettings' not found in /home/www.com/public_html/modules/resize.php on line 10 If I call resize.php from another PHP file which has AWS not included, it works fine. I load ezComponents like this: require 'ezc/Base/ezc_bootstrap.php'; It is installed as a PEAR package. Any idea someone?

  • Eclipse Plug-In Installation Issues

    - by Mudu
    Hi all I'm beginning to work with Eclipse for some Java development. I'm quite new to Eclipse, as I am a Visual Studio developer normally. I tried to install the CheckStyle Eclipse Plug-In and Subversive, using the Eclipse "Install new Software" feature. No errors, everything seems to have worked well. Clicking on "What software is already installed?" in the Install-dialogue shows me a list of installed plug-ins. Both Subversive and CheckStyle for Eclipse are listed. My only problem is that neither of them "work", that means I cannot see any new UI elements. According to the manual I have, I should see a new node "CheckStyle" in a project's properties. I haven't. I don't know exactly what Subversive looks like, but I'm sure there's a way to conveniently perform check-out operations etc. Manually copying the downloaded plug-in to the dropins-folder and restarting Eclipse subsequently does not help either. Is there a way to reliably find out whether there occurred any errors - I have no error message at all, what drives me crazy and makes the problem pretty difficult to describe/Google... Any help would be very cool! Cheers Matthias

  • Asp.Net MVC Tutorial Unit Tests

    I am working through Steve Sanderson's book Pro ASP.NET MVC Framework and I having some issues with two unit tests which produce errors.

  • Background image in a JFrame.

    - by thepandaatemyface
    Hi, This question has been asked a lot but everywhere the answers fall short. I can get a JFrame to display a background image just fine by extending JPanel and overriding paintComponent, like so: class BackgroundPanel extends JPanel { private ImageIcon imageIcon; public BackgroundPanel() { this.imageIcon = Icons.getIcon("foo"); } @Override protected void paintComponent(Graphics g) { super.paintComponent(g); g.drawImage(imageIcon.getImage(), 0,0,imageIcon.getIconWidth(),imageIcon.getIconHeight(),this); } } But now, how do you add a component on top of that background? When I go JFrame w = new JFrame() ; Container cp = w.getContentPane(); cp.setLayout(null); BackgroundPanel bg = new BackgroundPanel(); cp.add(bg); JPanel b = new JPanel(); b.setSize(new Dimension(30, 40)); b.setBackground(Color.red); cp.add(b); w.pack() w.setVisible(true) It shows the little red square (or any other component) and not the background, but when I remove cp.setLayout(null);, the background shows up but not my other component. I'm guessing this has something to do with the paintComponent not being called by the null LayoutManager, but I'm not at all familiar with how LayoutManagers work (this is a project for college and the assignment specifically says not to use a LayoutManager) When i make the image the background has to display null (and so, transparant (??)) the red square shows up so it might be that the background is actually above my other components) Does anyone anyone have any ideas? Thanks

  • ASP.NET/C# - Deserialize XML, XSD.exe created multiple classes

    - by Barryman9000
    I'm trying to deserialize some XML (returned from a web service) into an object that I created using XSD.exe. The XSD executable created a .CS file with a different partial class for each parent node in the XML. For Example, the beginning of the XML looks like this (why can't I post xml here? sorry, this is ugly): <disclaimer><notificationDescription>Additional charges will apply.</notificationDescription></disclaimer><quote><masterQuote></masterQuote></quote> And the Class generated by the XSD.exe has a partial class named disclaimer with a get; set; string for notificationDescription. And another partial class for quoteMasterQuote with the corresponding child nodes as public strings. How can I deserialize this XML file into multiple classes? I found this code, but it seems like it'll only work for one object. public static PricingResponse2 DeSerialize(string _xml) { PricingResponse2 _resp = new PricingResponse2(); StringReader _strReader = new StringReader(_xml); XmlSerializer _serializer = new XmlSerializer(_resp.GetType()); XmlReader _xmlReader = new XmlTextReader(_strReader); try { _resp = (PricingResponse2)_serializer.Deserialize(_xmlReader); return _resp; } catch (Exception ex) { string _error = ex.Message; throw; } finally { _xmlReader.Close(); _strReader.Close(); _strReader.Dispose(); } } This is the first time I've tried this, so I'm a little lost.

ItemSpec iSpec = new ItemSpec("{0}/{1}".FormatString(this.source, fileAndVersion.Key), RecursionType.None); GetItemAndVersionSpec(fileAndVersion.Key, fileAndVersion.Value, out vs, out i); labelSpecs.Add(new LabelItemSpec(iSpec, vs, false)); } this.vcServer.CreateLabel(label, labelSpecs.ToArray(), LabelChildOption.Merge); (there are some extension methods in there... this is all largely lifted from this blog post) The thing that concerns me is things like this in the MSDN docs: This enumeration supports the .NET Framework infrastructure and is not intended to be used directly from your code. So MSDN is telling me not to use that enumeration (LabelChildOption), which is afaik the only way to create a label and add it to a file. Is there a better way? Is this sort of a "grey" area in the TFS API?

  • Marshalling C# com items when using recursion

    - by Kevin
    I am using the SourceSafe COM object (SourceSafeTypeLib) from C# to automate a SourceSafe recursive get (part of a larger build process). The recursive function is shown below. How do I ensure that all the COM objects created in the foreach loop get released correctly? /// <summary> /// Recursively gets files/projects from SourceSafe (this is a recursive function). /// </summary> /// <param name="vssItem">The VSSItem to get</param> private void GetChangedFiles(VSSItem vssItem) { // 'If the object is a file perform the diff, // 'If not, it is a project, so use recursion to go through it if(vssItem.Type == (int)VSSItemType.VSSITEM_FILE) { bool bDifferent = false; //file is different bool bNew = false; //file is new //Surround the diff in a try-catch block. If a file is new(doesn't exist on //the local filesystem) an error will be thrown. Catch this error and record it //as a new file. try { bDifferent = vssItem.get_IsDifferent(vssItem.LocalSpec); } catch { //File doesn't exist bDifferent = true; bNew = true; } //If the File is different(or new), get it and log the message if(bDifferent) { if(bNew) { clsLog.WriteLine("Getting " + vssItem.Spec); } else { clsLog.WriteLine("Replacing " + vssItem.Spec); } string strGetPath = vssItem.LocalSpec; vssItem.Get(ref strGetPath, (int)VSSFlags.VSSFLAG_REPREPLACE); } } else //Item is a project, recurse through its sub items { foreach(VSSItem fileItem in vssItem.get_Items(false)) { GetChangedFiles(fileItem); } } }

  • c# opennetCF background worker stops after 100 iterations

    - by ikky
    Hi. I have a background worker that stops after 100 iterations. Like this: BackgroundWorker bgWorker = new BackgroundWorker(); bgWorker.WorkerReportsProgress = true; bgWorker.WorkerSupportsCancellation = true; bgWorker.DoWork += new OpenNETCF.ComponentModel.DoWorkEventHandler(this.bgWorker_DoWork); bgWorker.RunWorkerCompleted += new OpenNETCF.ComponentModel.RunWorkerCompletedEventHandler(this.bgWorker_RunWorkerCompleted); bgWorker.ProgressChanged += new OpenNETCF.ComponentModel.ProgressChangedEventHandler(this.bgWorker_ProgressChanged); private void bgWorker_DoWork(object sender, DoWorkEventArgs e) { for(i=0; i<300; i++) { bgWorker.ReportProgress(i, i); } } private void bgWorker_ProgressChanged(object sender, ProgressChangedEventArgs e) { this.labelProgress.Text = e.UserState.ToString(); } private void bgWorker_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e) { MessageBox.Show("finished loading..."); } What happens is that the labelProgress' value stops at 100, and the messagebox pops up and says "finished loading...". Anybody have an idea of what is wrong. Why does the thread stop at the 101 iteration? Thanks in advance.

  • Facebook Graph API - Image Uploading (as3/flash)

    - by lollertits
    I have been trying to get a bit more familiar with the Graph API for facebook. Its very convenient although the documentation is poor at some places. Im having trouble uploading an image to an album. Anyone know how to do it ? This is the code im currently working on :) private function uploadNewPic(albumId:String):void { var bmd1:BitmapData = new BitmapData(200, 200, false, 0x666666); var bm1:Bitmap = new Bitmap(bmd1); var jpgEncoder:JPGEncoder = new JPGEncoder(); var ba:ByteArray = jpgEncoder.encode(bmd1); var data:URLVariables = new URLVariables(); data.message = "Message"; data.image = ba; data.photos = ba; data.url = ba; var method:String = URLRequestMethod.POST; var loader:URLLoader = facebook.call(albumId + "/photos", data, method); loader.addEventListener(FacebookOAuthGraphEvent.ERROR, onPicError); loader.addEventListener(FacebookOAuthGraphEvent.DATA, onPicUploaded); } Im pretty much down to trial and error :) Any ideas ?

  • Problem Binding a ObservableCollection to a ListBox in WPF/MVVM

    - by alexqs
    I'm working in some code , using wpf and starting to use mvvm. So far i have no problem, when i have one element and I have to show the values of it in the screen (binding of the specific name of the property). But now, i have to work with a property list , not knowing the names of it. So I created a class, named GClass, that only have two propierties, name and value. I created the ObservableCollection, and fill for now with direct values, and asign the view (lstview) datacontext with the object i have created. But I cant see any result, it always shows a blank listbox. Can someone tell me if see why is happening ? Code of c# VDt = new ObservableCollection<GClass>(); var vhDt = message.SelectSingleElement(typeof (Vh)) as Vehiculo; if(vhDt != null) { VDt.Add(new GClass() {Name = "Numero: ", Value = ""}); VDt.Add(new GClass() {Name = "Marca: ", Value = ""}); VDt.Add(new GClass() {Name = "Conductor: ", Value = ""}); lstview.DataContext = this; _regionManager.RegisterViewWithRegionInIndex(RegionNames.MainRegion, lstview, 0); Code of the view <ListBox Margin="5,5,5,25" ItemsSource="{Binding VDt}"> <ListBox.Template> <ControlTemplate> <ListViewItem Content="{Binding Name}"></ListViewItem> <ListViewItem Content="{Binding Value}"></ListViewItem> </ControlTemplate> </ListBox.Template> </ListBox> I have research here, but i cant see, what I'm doing wrong. I will apreciate if someone help me.

  • How to persist options selected in AlertDialog spawned from ItemizedOverlay onTap method

    - by ahsteele
    In the description of how to add a list of options to an AlertDialog the official Android documentation alludes to saving a users preferences with one of the "data storage techniques." The examples assume the AlertDialog has been spawned within an Activity class. In my case I've created a class that extends ItemizedOverlay. This class overrides the onTap method and uses an AlertDialog to prompt the user to make a multi-choice selection. I would like to capture and persist the selections for each OverlayItem they tap on. The below code is the onTap method I've written. It functions as written but doesn't yet do what I'd hope. I'd like to capture and persist each selection made by the user to be used later. How do I do that? Is using an AlertDialog in this manner a good idea? Are there better options? protected boolean onTap(int index) { OverlayItem item = _overlays.get(index); final CharSequence[] items = { "WiFi", "BlueTooth" }; final boolean[] checked = { false, false }; AlertDialog.Builder builder = new AlertDialog.Builder(_context); builder.setTitle(item.getTitle()); builder.setMultiChoiceItems(items, checked, new DialogInterface.OnMultiChoiceClickListener() { @Override public void onClick(DialogInterface dialog, int item, boolean isChecked) { // for now just show that the user touched an option Toast.makeText(_context, items[item], Toast.LENGTH_SHORT).show(); } }); builder.setPositiveButton("Okay", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int id) { // should I be examining what was checked here? dialog.dismiss(); } }); builder.setNegativeButton("Cancel", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int id) { dialog.cancel(); } }); AlertDialog alert = builder.create(); alert.show(); return true; }

  • Factories, or Dependency Injection for object instantiation in WCF, when coding against an interface

    - by Saajid Ismail
    Hi I am writing a client/server application, where the client is a Windows Forms app, and the server is a WCF service hosted in a Windows Service. Note that I control both sides of the application. I am trying to implement the practice of coding against an interface: i.e. I have a Shared assembly which is referenced by the client application. This project contains my WCF ServiceContracts and interfaces which will be exposed to clients. I am trying to only expose interfaces to the clients, so that they are only dependant on a contract, not any specific implementation. One of the reasons for doing this is so that I can have my service implementation, and domain change at any time without having to recompile and redeploy the clients. The interfaces/contracts will in this case not change. I only need to recompile and redeploy my WCF service. The design issue I am facing now, is: on the client, how do I create new instances of objects, e.g. ICustomer, if the client doesn't know about the Customer concrete implementation? I need to create a new customer to be saved to the DB. Do I use dependency injection, or a Factory class to instantiate new objects, or should I just allow the client to create new instances of concrete implementations? I am not doing TDD, and I will typically only have one implementation of ICustomer or any other exposed interface.
