  • Preference List only shows first element

    - by jmunoz
    I am developing a PreferenceActivity with custom Preference views. My problem is that I created a view with a ListView and it only shows the first element.

  • A little bit of Ajax goes a long way

    - by Holland
    ..except when you're having problems. My problem is this: I have a hierarchical list of categories stored in a database which I wish to output in a dropdown list. The hierarchy comes into place when the subcategories are to be displayed, which are dependent on a parent id (which equals out to the first seven or so main categories listed). My thoughts are relatively simple: when the user clicks the dynamically allocated list of main categories, they are clicking on an option tag. For each option tag, an id (i.e., the parent) is listed in the value attribute, as well as an argument which is sent to a Javascript function which then uses AJAX to get the data via PHP and sends it to my 'javascript.php' file. The file then does magic, and populates the subcategory list, which is dependent on the main category selected. I believe I have the idea down, it's just that I'm implementing the solution improperly, for some reason. Here's what I have so far: from javascript.php <script type="text/javascript" src=<?=JPATH_BASE.DS.'includes'.DS.'jquery.js';?>> var ajax = { ajax.sendAjaxData = function(method, url, dataTitle, ajaxData) { $.ajax({ type: 'post', url: "C:/wamp/www/patention/components/com_adsmanagar/views/edit/tmpl/javascript.php", data: { 'data' : ajaxData }, success: function(result){ // we have the response alert("Your request was successful." + result); }, error: function(e){ alert('Error: ' + e); } }); } ajax.printSubCategoriesOnClick = function(parent) { alert("hello world!"); ajax.sendAjaxData('post', 'javascript.php', 'data' parent); <?php $categories = $this->formData->getCategories($_POST['data']); ?> ajax.printSubCategories(<?=$categories;?>); } ajax.printSubCategories = function(categories) { var select = document.getElementById("subcategories"); for (var i = 0; i < categories.length; i++) { var opt = document.createElement("option"); opt.text = categories['name']; opt.value = categories['id']; } } } </script> the function used to populate the form data function populateCategories($parent, FormData $formData) { $categories = $formData->getCategories($parent); echo "<pre>"; print_r($categories); echo "</pre>"; foreach($categories as $section => $row){ ?> <option value=<?=$row['id'];?> onclick="ajax.printSubCategoriesOnClick(<?=$row['id']?>)"> <? echo $row['name']; ?> </option> <?php } } The problem is that when I try to do a print_r on my $_POST variable, nothing shows up. I also receive an "undefined index" error (which refers to the key I set for the data type). I'm thinking that for some reason, the data is being sent to my form.php file, or my default.php file which includes both the form.php and javascript.php files via a function. Is there something specific that I'm missing here? Just looking up basic AJAX syntax (via jQuery) hasn't helped out, unfortunately.

  • Problem with custom paging in ASP.NET

    - by JohnCC
    I'm trying to add custom paging to my site using the ObjectDataSource paging. I believe I've correctly added the stored procedures I need, and brought them up through the DAL and BLL. The problem I have is that when I try to use it on a page, I get an empty datagrid. <%@ Page Language="C#" AutoEventWireup="true" CodeFile="PageTest.aspx.cs" Inherits="developer_PageTest" %> <!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 runat="server"> <title></title> </head> <body> <form id="form1" runat="server"> <div> <asp:ObjectDataSource ID="ObjectDataSource1" SelectMethod="GetMessagesPaged" EnablePaging="true" SelectCountMethod="GetMessagesCount" TypeName="MessageTable" runat="server" > <SelectParameters> <asp:Parameter Name="DeviceID" Type="Int32" DefaultValue="112" /> <asp:Parameter Name="StartDate" Type="DateTime" DefaultValue="" ConvertEmptyStringToNull="true"/> <asp:Parameter Name="EndDate" Type="DateTime" DefaultValue="" ConvertEmptyStringToNull="true"/> <asp:Parameter Name="BasicMatch" Type="Boolean" ConvertEmptyStringToNull="true" DefaultValue="" /> <asp:Parameter Name="ContainsPosition" Type="Boolean" ConvertEmptyStringToNull="true" DefaultValue="" /> <asp:Parameter Name="Decoded" Type="Boolean" ConvertEmptyStringToNull="true" DefaultValue="" /> <%-- <asp:Parameter Name="StartRowIndex" Type="Int32" DefaultValue="10" /> <asp:Parameter Name="MaximumRows" Type="Int32" DefaultValue="10" /> --%> </SelectParameters> </asp:ObjectDataSource> <asp:GridView ID="GridView1" runat="server" DataSourceID="ObjectDataSource1" AllowPaging="true" PageSize="10"></asp:GridView> <br /> <asp:Label runat="server" ID="lblCount"></asp:Label> </div> </form> </body> </html> When I set EnablePaging to false on the ODS, and add the commented out StartRowIndex and MaximumRows params in the markup, I get data so it really seems like the data layer is behaving as it should. There's code in code file to put the value of the GetMessagesCount call in the lblCount, and that always has a sensible value in it. I've tried breaking in the BLL and stepping through, and the backend is getting called, and it is returning what looks like the right information and data, but somehow between the ODS and the GridView it's vanishing. I created a mock data source which returned numbered rows of random numbers and attached it to this form, and the custom paging worked so I think my understanding of the technique is good. I just can't see why it fails here! Any help really appreciated. (EDIT .. here's the code behind). using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; using System.ComponentModel; public partial class developer_PageTest : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { lblCount.Text = String.Format("Count = {0}", MessageTable.GetMessagesCount(112, null, null, null, null, null)) } }

  • Code that Worked with MultiView fails with Wizard ASP.NET

    - by davemackey
    I originally created a process that occurred by transitioning between views in a multiview and it worked fine. Now, I've moved this same code into a ASP.NET Wizard and it keeps throwing an error at the second step. The error is: Method 'System.Object AndObject(System.Object, System.Object)' has no supported translation to SQL. Any ideas why this would occur when moving the code into the wizard? I'm sure its something stupid, but I've checked over the code 3-4 times now and it appears identical operationally.

  • Overwrite archetypes in Maven

    - by Random
    Hello again! I'm having some trouble using Maven for my archetypes and I will need to overwrite some. I launch an instruction that does an archetype:generate in an archetype already existing directory. Is there a parameter that let's me overwrite existing archetypes? I have search the maven definitve guide but it states that the only parameters accepted are: -DgroupId -DartifactId -Dversion -DpackageName -DarchetypeGroupId -DarchetypeArtifactId -DarchetypeVersion -DinteractiveMode I could just search the directory and delete the files, but this proccess is going to be done automatically (so no human involved, no brains involved) and I wouldn't like he machine deleting things around. Thanks for all! Edit: I almost forgot, here is some maven trace: [INFO] Scanning for projects... [INFO] Searching repository for plugin with prefix: 'archetype'.

  • Safe, standard way to load images in ListView on a different thread?

    - by Po
    Before making this question, I have searched and read these ones: http://stackoverflow.com/questions/541966/android-how-do-i-do-a-lazy-load-of-images-in-listview http://stackoverflow.com/questions/1409623/android-issue-with-lazy-loading-images-into-a-listview My problem is I have a ListView, where: Each row contains an ImageView, whose content is to be loaded from the internet Each row's view is recycled as in ApiDemo's List14 What I want ultimately: Load images lazily, only when the user scrolls to them Load images on different thread(s) to maintain responsiveness My current approach: In the adapter's getView() method, apart from setting up other child views, I launch a new thread that loads the Bitmap from the internet. When that loading thread finishes, it returns the Bitmap to be set on the ImageView (I do this using AsyncTask or Handler). Because I recycle ImageViews, it may be the case that I first want to set a view with Bitmap#1, then later want to set it to Bitmap#2 when the user scrolls down. Bitmap#1 may happen to take longer than Bitmap#2 to load, so it may end up overwriting Bitmap#2 on the view. I solve this by maintaining a WeakHashMap that remembers the last Bitmap I want to set for that view. Below is somewhat a pseudocode for my current approach. I've ommitted other details like caching, just to keep the thing clear. public class ImageLoader { // keeps track of the last Bitmap we want to set for this ImageView private static final WeakHashMap<ImageView, AsyncTask> assignments = new WeakHashMap<ImageView, AsyncTask>(); /** Asynchronously sets an ImageView to some Bitmap loaded from the internet */ public static void setImageAsync(final ImageView imageView, final String imageUrl) { // cancel whatever previous task AsyncTask oldTask = assignments.get(imageView); if (oldTask != null) { oldTask.cancel(true); } // prepare to launch a new task to load this new image AsyncTask<String, Integer, Bitmap> newTask = new AsyncTask<String, Integer, Bitmap>() { protected void onPreExecute() { // set ImageView to some "loading..." image } protected Bitmap doInBackground(String... urls) { return loadFromInternet(imageUrl); } protected void onPostExecute(Bitmap bitmap) { // set Bitmap if successfully loaded, or an "error" image if (bitmap != null) { imageView.setImageBitmap(bitmap); } else { imageView.setImageResource(R.drawable.error); } } }; newTask.execute(); // mark this as the latest Bitmap we want to set for this ImageView assignments.put(imageView, newTask); } /** returns (Bitmap on success | null on error) */ private Bitmap loadFromInternet(String imageUrl) {} } Problem I still have: what if the Activity gets destroyed while some images are still loading? Is there any risk when the loading thread calls back to the ImageView later, when the Activity is already destroyed? Moreover, AsyncTask has some global thread-pool underneath, so if lengthy tasks are not canceled when they're not needed anymore, I may end up wasting time loading things users don't see. My current design of keeping this thing globally is too ugly, and may eventually cause some leaks that are beyond my understanding. Instead of making ImageLoader a singleton like this, I'm thinking of actually creating separate ImageLoader objects for different Activities, then when an Activity gets destroyed, all its AsyncTask will be canceled. Is this too awkward? Anyway, I wonder if there is a safe and standard way of doing this in Android. In addition, I don't know iPhone but is there a similar problem there and do they have a standard way to do this kind of task? Many thanks.

  • ASP.NET Send Image Attachment With Email Without Saving To Filesystem

    - by KGO
    I'm trying to create a form that will send an email with an attached image and am running into some problems. The form I am creating is rather large so I have created a small test form for the purpose of this question. The email will send and the attachment will exist on the email, but the image is corrupt or something as it is not viewable. Also.. I do not want to save the image to the filesystem. You may think it is convoluted to take the image file from the fileupload to a stream, but this is due to the fact that the real form I am working on will allow multiple files to be added through a single fileupload and will be saved in session, thus the images will not be coming from the fileupload control directly on submit.

  • Hudson + Jboss AS 7.1 + Maven 3 Project Build Error

    I've wanted to prepare an environment that I'm able to build my project and run my tests on a integration server. So I've installed an Jboss application server 7.1 and deployed hudson.war to it.

  • Sharing the model in MVP Winforms App

    - by Keith G
    I'm working on building up an MVP application (C# Winforms). My initial version is at http://stackoverflow.com/questions/1422343/ ... Now I'm increasing the complexity. I've broken out the code to handle two separate text fields into two view/presenter pairs. It's a trivial example, but it's to work out the details of multiple presenters sharing the same model. My questions are about the model: I am basically using a property changed event raised by the model for notifying views that something has changed. Is that a good approach? What if it gets to the point where I have 100 or 1000 properties? Is it still practical at that point? Is instantiating the model in each presenter with   NoteModel _model = NoteModel.Instance   the correct approach? Note that I do want to make sure all of the presenters are sharing the same data. If there is a better approach, I'm open to suggestions .... My code looks like this: NoteModel.cs public class NoteModel : INotifyPropertyChanged { private static NoteModel _instance = null; public static NoteModel Instance { get { return _instance; } } static NoteModel() { _instance = new NoteModel(); } private NoteModel() { Initialize(); } public string Filename { get; set; } public bool IsDirty { get; set; } public readonly string DefaultName = "Untitled.txt"; string _sText; public string TheText { get { return _sText; } set { _sText = value; PropertyHasChanged("TheText"); } } string _sMoreText; public string MoreText { get { return _sMoreText; } set { _sMoreText = value; PropertyHasChanged("MoreText"); } } public void Initialize() { Filename = DefaultName; TheText = String.Empty; MoreText = String.Empty; IsDirty = false; } private void PropertyHasChanged(string sPropName) { IsDirty = true; if (PropertyChanged != null) { PropertyChanged(this, new PropertyChangedEventArgs(sPropName)); } } public event PropertyChangedEventHandler PropertyChanged; } TextEditorPresenter.cs public class TextEditorPresenter { ITextEditorView _view; NoteModel _model = NoteModel.Instance; public TextEditorPresenter(ITextEditorView view)//, NoteModel model) { //_model = model; _view = view; _model.PropertyChanged += new PropertyChangedEventHandler(model_PropertyChanged); } void model_PropertyChanged(object sender, PropertyChangedEventArgs e) { if (e.PropertyName == "TheText") _view.TheText = _model.TheText; } public void TextModified() { _model.TheText = _view.TheText; } public void ClearView() { _view.TheText = String.Empty; } } TextEditor2Presenter.cs is essentially the same except it operates on _model.MoreText instead of _model.TheText. ITextEditorView.cs public interface ITextEditorView { string TheText { get; set; } } ITextEditor2View.cs public interface ITextEditor2View { string MoreText { get; set; } }

  • What is good practice in .NET system architecture design concerning multiple models and aggregates

    - by BuzzBubba
    I'm designing a larger enterprise architecture and I'm in a doubt about how to separate the models and design those. There are several points I'd like suggestions for: - models to define - way to define models Currently my idea is to define: Core (domain) model Repositories to get data to that domain model from a database or other store Business logic model that would contain business logic, validation logic and more specific versions of forms of data retrieval methods View models prepared for specifically formated data output that would be parsed by views of different kind (web, silverlight, etc). For the first model I'm puzzled at what to use and how to define the mode. Should this model entities contain collections and in what form? IList, IEnumerable or IQueryable collections? - I'm thinking of immutable collections which IEnumerable is, but I'd like to avoid huge data collections and to offer my Business logic layer access with LINQ expressions so that query trees get executed at Data level and retrieve only really required data for situations like the one when I'm retrieving a very specific subset of elements amongst thousands or hundreds of thousands. What if I have an item with several thousands of bids? I can't just make an IEnumerable collection of those on the model and then retrieve an item list in some Repository method or even Business model method. Should it be IQueryable so that I actually pass my queries to Repository all the way from the Business logic model layer? Should I just avoid collections in my domain model? Should I void only some collections? Should I separate Domain model and BusinessLogic model or integrate those? Data would be dealt trough repositories which would use Domain model classes. Should repositories be used directly using only classes from domain model like data containers? This is an example of what I had in mind: So, my Domain objects would look like (e.g.) public class Item { public string ItemName { get; set; } public int Price { get; set; } public bool Available { get; set; } private IList<Bid> _bids; public IQueryable<Bid> Bids { get { return _bids.AsQueryable(); } private set { _bids = value; } } public AddNewBid(Bid newBid) { _bids.Add(new Bid {.... } } Where Bid would be defined as a normal class. Repositories would be defined as data retrieval factories and used to get data into another (Business logic) model which would again be used to get data to ViewModels which would then be rendered by different consumers. I would define IQueryable interfaces for all aggregating collections to get flexibility and minimize data retrieved from real data store. Or should I make Domain Model "anemic" with pure data store entities and all collections define for business logic model? One of the most important questions is, where to have IQueryable typed collections? - All the way from Repositories to Business model or not at all and expose only solid IList and IEnumerable from Repositories and deal with more specific queries inside Business model, but have more finer grained methods for data retrieval within Repositories. So, what do you think? Have any suggestions?

  • Dynamic Scoped Resources in WPF/XAML?

    - by firoso
    I have 2 Xaml files, one containing a DataTemplate which has a resource definition for an Image brush, and the other containing a content control which presents this DataTemplate.

  • Why does Process Explorer cause highly targeted failure of some applications / basic UI functions in a high-power EC2 Windows instance?

    - by Dan Nissenbaum
    Update: I have determined that Process Explorer itself - the program I am using to debug a performance issue - seems to be the cause of the issue. See note, with updated question, at end. I am running a high-power (cc2.8xlarge) Amazon AWS EC2 Windows instance off of a boot EBS volume, provisioned at 2500 PIOPS, which was created from a snapshot of a previous boot volume. My purpose with the instance is to use it as a development workstation with many developer tools installed, such as Visual Studio, a local XAMPP stack, etc. I have upwards of 40 programs installed on the machine. The usability of the instance as a development machine often works quite well. The RDP lag is adequately small. I have used it for hours on end without problems for some of my most intense development tasks. As a result, I have just purchased a reserved instance, and I opted to rebuild my development machine starting from scratch with a Windows Server 2012 AMI. After having installed all of my desired/required applications for development over this past week, again the machine seems to often work well and I have worked for up to an hour at a time without problems doing heavy development work. However, I continue to run into catastrophic OS usability issues that may prevent me from being able to rely on this machine as a development machine. I would like to track down the source of the problem, if there is an easily identifiable source. (Update: I have tracked down the source to be Process Explorer, the very program I was using to debug the problem. See update at end.) The issues are as follows. (These are some primary examples) Some applications, after a period of adequate responsiveness, suddenly begin to respond very, very slowly to basic user interface actions such as clicking on menus and pressing Ctrl-Tab to switch between open documents. Two examples are UltraEdit and PhpEd. It typically takes ~2 seconds for a menu to appear, and ~4 seconds to switch between open documents. Additionally, insertion point motion in the editor is lagged by upwards of ~2 seconds. Process Explorer, which I am using to help debug the problem, seems to run acceptably for a couple of minutes, but on multiple occasions Process Explorer itself hangs completely. It hangs at the same time as the problems noted above. When it hangs, it is 100% unresponsive. Clicking on its taskbar icon neither causes it to come to the top or go behind, and its viewable area is filled with nothing but a region partially containing pure white and partially containing incomplete windows widgets that are unreadable, and that never change. Waiting 10 minutes does not clear the problem. Attempting to force-quit Process Explorer by right-clicking on its taskbar icon and choosing "Close Window" takes about 5 full minutes to exit (Process Explorer itself can't be used to exit Process Explorer, and it is registered as a Task Manager substitute). Other programs work just fine during this time. For example, Chrome tabs flip very quickly back and forth, menus pop open instantly, web pages load quickly, and typing in forms/web applications inside the browser works promptly. Another example of an application that works crisply is Filemaker - its menus open instantly, and switching views in this application occurs promptly. Other applications also work without issue. Also, switching between applications occurs promptly as well. It is only a handful of applications that exhibit the problem, with some primary examples given above. At first I thought that EBS IOPS might be a problem. Therefore, I ran Performance Monitor, and watched the "Disk Transfers/sec" monitor in real time. At no point did this measure come anywhere close to hitting the 2500 PIOPS provisioned for the EBS volume. The RAM was also well under the limit (~10 GB used out of 60 GB). I did notice that one CPU core (out of 32 logical cores) was fully thrashing at 100% (i.e., ~3.1%) during the problematic periods. This seems to indicate that a single CPU core is handling the menus / flipping between open documents (for some applications only) / managing the Process Explorer user interface, and that this single core was hosed for some reason during the problematic periods. Also note that I have a desktop workstation (Windows 7) that I also use as a development machine, via a remote connection, with a nearly identical set of programs installed, and this desktop workstation does not exhibit any of the problems I've discussed above. I have been using it heavily for well over a year now. Any suggestions regarding either the source of the problem, or steps I might take to investigate the source of the problem, would be appreciated. Thanks. Note: After extensive testing & investigation, I have noticed that when I quit Process Explorer, the problem vanishes and the system performance returns to normal, and then reappears quickly when I run Process Explorer again (note: again, the performance problems only appear for a subset of applications - other applications work perfectly fine during the same period). My question is therefore (thankfully) more specific: Why does Process Explorer cause highly targeted failure of some applications (including itself) and basic UI functions, in a high-power EC2 Windows instance?

  • How do I load an image from sd card into coverview

    - by Jolene
    I am doing an application which consists of a cover flow. Currently I am trying to make the cover flow images be obtained from the sd card. But I am not exactly sure how should I display the image. this is the image adapter: public class ImageAdapter extends BaseAdapter { int mGalleryItemBackground; private Context mContext; private FileInputStream fis; private Integer[] mImageIds = { //Instead of using r.drawable, i need to load the images from my sd card instead R.drawable.futsing, R.drawable.futsing2 }; private ImageView[] mImages; public ImageAdapter(Context c) { mContext = c; mImages = new ImageView[mImageIds.length]; } public int getCount() { return mImageIds.length; } public Object getItem(int position) { return position; } public long getItemId(int position) { return position; } @TargetApi(8) public View getView(int position, View convertView, ViewGroup parent) { int screenSize = getResources().getConfiguration().screenLayout & Configuration.SCREENLAYOUT_SIZE_MASK; ImageView i = new ImageView(mContext); i.setImageResource(mImageIds[position]); switch(screenSize) { case Configuration.SCREENLAYOUT_SIZE_XLARGE: //Toast.makeText(this, "Small screen",Toast.LENGTH_LONG).show(); Display display4 = ((WindowManager) context.getSystemService(Context.WINDOW_SERVICE)).getDefaultDisplay(); int rotation4 = display4.getRotation(); Log.d("XLarge:",String.valueOf(rotation4)); /** LANDSCAPE **/ if(rotation4 == 0 || rotation4 == 2) { i.setLayoutParams(new CoverFlow.LayoutParams(300, 300)); i.setScaleType(ImageView.ScaleType.CENTER_INSIDE); BitmapDrawable drawable = (BitmapDrawable) i.getDrawable(); drawable.setAntiAlias(true); return i; } /** PORTRAIT **/ else if (rotation4 == 1 || rotation4 == 3) { i.setLayoutParams(new CoverFlow.LayoutParams(650, 650)); i.setScaleType(ImageView.ScaleType.CENTER_INSIDE); BitmapDrawable drawable = (BitmapDrawable) i.getDrawable(); drawable.setAntiAlias(true); return i; } break; default: } return null; } /** Returns the size (0.0f to 1.0f) of the views * depending on the 'offset' to the center. */ public float getScale(boolean focused, int offset) { /* Formula: 1 / (2 ^ offset) */ return Math.max(0, 1.0f / (float)Math.pow(2, Math.abs(offset))); } } and this is how i download and save the file. I need to use the image saved and upload it into my coverflow // IF METHOD TO DOWNLOAD IMAGE void downloadFile() { new Thread(new Runnable(){ // RUN IN BACKGROUND THREAD TO AVOID FREEZING OF UI public void run(){ Bitmap bmImg; URL myFileUrl = null; try { //for (int i = 0; i < urlList.size(); i ++) //{ //url = urlList.get(i); myFileUrl = new URL("http://static.adzerk.net/Advertisers/d18eea9d28f3490b8dcbfa9e38f8336e.jpg"); // RETRIEVE IMAGE URL //} } catch (MalformedURLException e) { e.printStackTrace(); } try { HttpURLConnection conn = (HttpURLConnection) myFileUrl.openConnection(); conn.setDoInput(true); conn.connect(); InputStream in = conn.getInputStream(); Log.i("im connected", "Download"); bmImg = BitmapFactory.decodeStream(in); saveFile(bmImg); } catch (IOException e) { e.printStackTrace(); }} }).start(); // START THREAD } // SAVE THE IMAGE AS JPG FILE private void saveFile(Bitmap bmImg) { File filename; try { // GET EXTERNAL STORAGE, SAVE FILE THERE File storagePath = new File(Environment.getExternalStorageDirectory(),"Covers"); storagePath.mkdirs(); filename = new File(storagePath + "/image.jpg"); FileOutputStream out = new FileOutputStream(filename); bmImg.compress(Bitmap.CompressFormat.JPEG, 90, out); out.flush(); out.close(); MediaStore.Images.Media.insertImage(getContentResolver(),filename.getAbsolutePath(), filename.getName(), filename.getName()); // ONCE THE DOWNLOAD FINISHES, CLOSE DIALOG Toast.makeText(getApplicationContext(), "Image Saved!", Toast.LENGTH_SHORT).show(); } catch (Exception e) { e.printStackTrace(); } }

  • Why C# doesn't implement indexed properties ?

    - by Thomas Levesque
    I know, I know... Eric Lippert's answer to this kind of question is usually something like "because it wasn't worth the cost of designing, implementing, testing and documenting it". But still, I'd like a better explanation... I was reading this blog post about new C# 4 features, and in the section about COM Interop, the following part caught my attention : By the way, this code uses one more new feature: indexed properties (take a closer look at those square brackets after Range.) But this feature is available only for COM interop; you cannot create your own indexed properties in C# 4.0. OK, but why ? I already knew and regretted that it wasn't possible to create indexed properties in C#, but this sentence made me think again about it. I can see several good reasons to implement it : the CLR supports it (for instance, PropertyInfo.GetValue has an index parameter), so it's a pity we can't take advantage of it in C# it is supported for COM interop, as shown in the article (using dynamic dispatch) it is implemented in VB.NET it is already possible to create indexers, i.e. to apply an index to the object itself, so it would probably be no big deal to extend the idea to properties, keeping the same syntax and just replacing this with a property name It would allow to write that kind of things : public class Foo { private string[] _values = new string[3]; public string Values[int index] { get { return _values[index]; } set { _values[index] = value; } } } Currently the only workaround that I know is to create an inner class (ValuesCollection for instance) that implements an indexer, and change the Values property so that it returns an instance of that inner class. This is very easy to do, but annoying... So perhaps the compiler could do it for us ! An option would be to generate an inner class that implements the indexer, and expose it through a public generic interface : // interface defined in the namespace System public interface IIndexer<TIndex, TValue> { TValue this[TIndex index] { get; set; } } public class Foo { private string[] _values = new string[3]; private class <>c__DisplayClass1 : IIndexer<int, string> { private Foo _foo; public <>c__DisplayClass1(Foo foo) { _foo = foo; } public string this[int index] { get { return _foo._values[index]; } set { _foo._values[index] = value; } } } private IIndexer<int, string> <>f__valuesIndexer; public IIndexer<int, string> Values { get { if (<>f__valuesIndexer == null) <>f__valuesIndexer = new <>c__DisplayClass1(this); return <>f__valuesIndexer; } } } But of course, in that case the property would actually return a IIndexer<int, string>, and wouldn't really be an indexed property... It would be better to generate a real CLR indexed property. What do you think ? Would you like to see this feature in C# ? If not, why ?

  • How do you set Android ViewPager to encompass only one View or Layout?

    - by Kyle
    I am struggling with the concepts needed to properly implement a view pager. By following some tutorials and referencing developer.android.com, I am able to get a view pager almost fully functional. The pager will flip through several text views that have been setup to say "My Message 0" through "My Message 9". The problem is that the view pager also flips the button on the bottom of the activity and the red block that is right above the button. I would like to have the view pager only cycle through the text. Would you please help me understand what I'm doing wrong? I have an activity that represents a dashboard: public class DashBoard extends FragmentActivity { private static final int NUMBER_OF_PAGES = 10; private ViewPager mViewPager; private MyFragmentPagerAdapter mMyFragmentPagerAdapter; public void onCreate(Bundle icicle){ super.onCreate(icicle); setContentView(R.layout.dashboard); mViewPager = (ViewPager) findViewById(R.id.viewpager); mMyFragmentPagerAdapter = new MyFragmentPagerAdapter(getSupportFragmentManager()); mViewPager.setAdapter(mMyFragmentPagerAdapter); } private static class MyFragmentPagerAdapter extends FragmentPagerAdapter{ public MyFragmentPagerAdapter(FragmentManager fm) { super(fm); } @Override public Fragment getItem(int index) { return PageFragment.newInstance("My Message " + index); } @Override public int getCount(){ return NUMBER_OF_PAGES; } } and a class for the page fragment: public class PageFragment extends Fragment { public static PageFragment newInstance(String title){ PageFragment pageFragment = new PageFragment(); Bundle bundle = new Bundle(); bundle.putString("title", title); pageFragment.setArguments(bundle); return pageFragment; } @Override public void onCreate(Bundle icicle){ super.onCreate(icicle); } @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle icicle){ View view = inflater.inflate(R.layout.dashboard, container, false); TextView textView = (TextView) view.findViewById(R.id.textViewPage); textView.setText(getArguments().getString("title")); return view; } } and finally, my xml for the dashboard: <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:id="@+id/dashbaordLabel" android:layout_width="match_parent" android:layout_height="wrap_content" > <android.support.v4.view.ViewPager android:id="@+id/viewpager" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_alignParentTop="true" android:layout_alignParentLeft="true" /> <TextView android:id="@+id/textViewPage" android:layout_width = "match_parent" android:layout_height= "wrap_content" /> <Button android:id="@+id/newGoalButton" android:layout_width="match_parent" android:layout_height="wrap_content" android:text="@string/stringNewGoal" android:layout_alignParentBottom="true" android:layout_alignParentLeft="true" android:onClick="createNewGoal" /> <RelativeLayout android:id="@+id/SpaceBottom" android:layout_width="match_parent" android:layout_height="75dp" android:layout_above="@id/newGoalButton" android:background="@color/red" > </RelativeLayout> </RelativeLayout> A note about my xml, I tried wrapping the text view in some view pager tags eg: <android.support.v4.view.ViewPager android:id="@+id/viewpager" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_alignParentTop="true" android:layout_alignParentLeft="true" > <TextView android:id="@+id/textViewPage" android:layout_width = "match_parent" android:layout_height= "wrap_content" /> </android.support.v4.view.ViewPager> But all that did was make the text view disappear from the screen, while the button and red block still cycled as in the original issue.

  • Parsing JSON into XML using Windows Phone

    - by Henry Edwards
    I have this code, but can't get it all working. I am trying to get a json string into xml. So that I can get a list of items when i parse the data. Is there a better way to parse json into xml. If so what's the best way to do it, and if possible could you give me a working example? The URL that is in the code is not the URL that i am using using System; using System.Collections.Generic; using System.Linq; using System.Net; using System.Windows; using System.Windows.Controls; using System.Windows.Documents; using System.Windows.Input; using System.Windows.Media; using System.Windows.Media.Animation; using System.Windows.Shapes; using Microsoft.Phone.Controls; using Newtonsoft.Json; using Newtonsoft.Json.Serialization; using Newtonsoft.Json.Converters; using Newtonsoft.Json.Utilities; using Newtonsoft.Json.Linq; using Newtonsoft.Json.Schema; using Newtonsoft.Json.Bson; using System.Xml; using System.Xml.Serialization; using System.Xml.Linq; using System.Xml.Linq.XDocument; using System.IO; namespace WindowsPhonePanoramaApplication3 { public partial class Page2 : PhoneApplicationPage { public Page2() { InitializeComponent(); } private void Form1_Load(object sender, EventArgs e1) { /* because the origional JSON string has multiple root's this needs to be added */ string json = "{BFBC2_GlobalStats:"; json += DownlodUrl("http://api.bfbcs.com/api/xbox360?globalstats"); json += "}"; XmlDocument doc = (XmlDocument)JsonConvert.DeserializeObject(json); textBox1.Text = GetXmlString(doc); } private string GetXmlString() { throw new NotImplementedException(); } private string DownlodUrl(string url) { string result = null; try { WebClient client = new WebClient(); result = client.DownloadString(url); } catch (Exception ex) { // handle error result = ex.Message; } return result; } private string GetXmlString(XmlDocument xmlDoc) { sw = new StringWriter(); XmlTextWriter xw = new XmlTextWriter(sw); xw.Formatting = System.Xml.Formatting.Indented; xmlDoc.WriteTo(xw); return sw.ToString(); } } } The URL outputs the following code: {"StopName":"Race Hill", "stopId":7553, "NaptanCode":"bridwja", "LongName":"Race Hill", "OperatorsCode1":" 5", "OperatorsCode2":" ", "OperatorsCode3":" ", "OperatorsCode4":"bridwja", "Departures":[ { "ServiceName":"", "Destination":"", "DepartureTimeAsString":"", "DepartureTime":"30/01/2012 00:00:00", "Notes":""}` Thanks for your responses. So Should i just leave the data a json and then view the data via that??? Is this a way to show the data from a json string. public void Load() { // form the URI UriBuilder uri = new UriBuilder("http://mysite.com/events.json"); WebClient proxy = new WebClient(); proxy.OpenReadCompleted += new OpenReadCompletedEventHandler(OnReadCompleted); proxy.OpenReadAsync(uri.Uri); } void OnReadCompleted(object sender, OpenReadCompletedEventArgs e) { if (e.Error == null) { var serializer = new DataContractJsonSerializer(typeof(EventList)); var events = (EventList)serializer.ReadObject(e.Result); foreach (var ev in events) { Items.Add(ev); } } } public ObservableCollection<EventDetails> Items { get; private set; } Edit: Have now kept the url as json and have now got it working by using the json way.

  • Adding sections to a plist for Xcode for use in Cocoa touch Table View

    - by Steve
    I am a beginning iPhone SDK programmer. I built a simple practice application I am trying to use to learn more about table views. It's an app that loads football teams from a plist and displays them in a table view with their stadium name and logo. Tapping the team goes to a detail view for that team. I am trying to understand how to add sections to this, so that I might have a couple of teams in one section and others in another section, etc. I would assume I need to both re-structure my plist and change the code to read arrays from the different levels of the plist? To begin, I had a plist with the root array consisting of 3 dictionaries, one for each team. Each dictionary had 3 keys, "name" "stadium" and "logo". This works fine. I am loading it via: NSString *path = [[NSBundle mainBundle] pathForResource:@"teams" ofType:@"plist"]; teams = [[NSMutableArray alloc] initWithContentsOfFile:path]; and then // Configure the cell. NSDictionary *team = [teams objectAtIndex:indexPath.row]; cell.textLabel.text = [team objectForKey:@"name"]; NSString *imgPath = [team valueForKey:@"logo"]; cell.imageView.image = [UIImage imageNamed:imgPath]; cell.detailTextLabel.text =[team objectForKey:@"stadium"]; return cell; No problem. But now I wanted the sections, so I changed my plist to: <array> <dict> <key>teams 1</key> <array> <dict> <key>name</key> <string>Packers</string> <key>stadium</key> <string>Lambeau Field</string> <key>logo</key> <string>packers.jpg</string> </dict> <dict> <key>name</key> <string>Jets</string> <key>stadium</key> <string>Giants Stadium</string> <key>logo</key> <string>jets_logo.jpg</string> </dict> </array> </dict> <dict> <key>teams 2</key> <array> <dict> <key>name</key> <string>Cincinnati Bengals</string> <key>stadium</key> <string>Paul Brown Stadium</string> <key>logo</key> <string>bengals.jpg</string> </dict> </array> </dict> And I am unsure how to modify the viewDidLoad to assign the sections to one NSArray and the teams "level" to another array.

  • Linux policy routing - packets not coming back

    - by Bugsik
    i am trying to set up policy routing on my home server. My network looks like this: Host routed VPN gateway Internet link through VPN 192.168.0.35/24 ---> 192.168.0.5/24 ---> 192.168.0.1 DSL router 10.200.2.235/22 .... .... 10.200.0.1 VPN server The traffic from 192.168.0.32/27 should be and is routed through VPN. I wanted to define some routing policies to route some traffic from 192.168.0.5 through VPN as well - for start - from user with uid 2000. Policy routing is done using iptables mark target and ip rule fwmark. The problem: When connecting using user 2000 from 192.168.0.5 tcpdump shows outgoing packets, but nothing comes back. Traffic from 192.168.0.35 works fine (here I am not using fwmark but src policy).

  • Get User SID From Logon ID (Windows XP and Up)

    - by Dave Ruske
    I have a Windows service that needs to access registry hives under HKEY_USERS when users log on, either locally or via Terminal Server. I'm using a WMI query on win32_logonsession to receive events when users log on, and one of the properties I get from that query is a LogonId. To figure out which registry hive I need to access, now, I need the users's SID, which is used as a registry key name beneath HKEY_USERS. In most cases, I can get this by doing a RelatedObjectQuery like so (in C#): RelatedObjectQuery relatedQuery = new RelatedObjectQuery( "associators of {Win32_LogonSession.LogonId='" + logonID + "'} WHERE AssocClass=Win32_LoggedOnUser Role=Dependent" ); where "logonID" is the logon session ID from the session query. Running the RelatedObjectQuery will generally give me a SID property that contains exactly what I need. There are two issues I have with this. First and most importantly, the RelatedObjectQuery will not return any results for a domain user that logs in with cached credentials, disconnected from the domain. Second, I'm not pleased with the performance of this RelatedObjectQuery --- it can take up to several seconds to execute. Here's a quick and dirty command line program I threw together to experiment with the queries. Rather than setting up to receive events, this just enumerates the users on the local machine: using System; using System.Collections.Generic; using System.Text; using System.Management; namespace EnumUsersTest { class Program { static void Main( string[] args ) { ManagementScope scope = new ManagementScope( "\\\\.\\root\\cimv2" ); string queryString = "select * from win32_logonsession"; // for all sessions //string queryString = "select * from win32_logonsession where logontype = 2"; // for local interactive sessions only ManagementObjectSearcher sessionQuery = new ManagementObjectSearcher( scope, new SelectQuery( queryString ) ); ManagementObjectCollection logonSessions = sessionQuery.Get(); foreach ( ManagementObject logonSession in logonSessions ) { string logonID = logonSession["LogonId"].ToString(); Console.WriteLine( "=== {0}, type {1} ===", logonID, logonSession["LogonType"].ToString() ); RelatedObjectQuery relatedQuery = new RelatedObjectQuery( "associators of {Win32_LogonSession.LogonId='" + logonID + "'} WHERE AssocClass=Win32_LoggedOnUser Role=Dependent" ); ManagementObjectSearcher userQuery = new ManagementObjectSearcher( scope, relatedQuery ); ManagementObjectCollection users = userQuery.Get(); foreach ( ManagementObject user in users ) { PrintProperties( user.Properties ); } } Console.WriteLine( "\nDone! Press a key to exit..." ); Console.ReadKey( true ); } private static void PrintProperty( PropertyData pd ) { string value = "null"; string valueType = "n/a"; if ( null == pd.Value ) value = "null"; if ( pd.Value != null ) { value = pd.Value.ToString(); valueType = pd.Value.GetType().ToString(); } Console.WriteLine( " \"{0}\" = ({1}) \"{2}\"", pd.Name, valueType, value ); } private static void PrintProperties( PropertyDataCollection properties ) { foreach ( PropertyData pd in properties ) { PrintProperty( pd ); } } } } So... is there way to quickly and reliably obtain the user SID given the information I retrieve from WMI, or should I be looking at using something like SENS instead?

  • Xen DomU on DRBD device: barrier errors

    - by Halfgaar
    I'm testing setting up a Xen DomU with a DRBD storage for easy failover. Most of the time, immediatly after booting the DomU, I get an IO error: [ 3.153370] EXT3-fs (xvda2): using internal journal [ 3.277115] ip_tables: (C) 2000-2006 Netfilter Core Team [ 3.336014] nf_conntrack version 0.5.0 (3899 buckets, 15596 max) [ 3.515604] init: failsafe main process (397) killed by TERM signal [ 3.801589] blkfront: barrier: write xvda2 op failed [ 3.801597] blkfront: xvda2: barrier or flush: disabled [ 3.801611] end_request: I/O error, dev xvda2, sector 52171168 [ 3.801630] end_request: I/O error, dev xvda2, sector 52171168 [ 3.801642] Buffer I/O error on device xvda2, logical block 6521396 [ 3.801652] lost page write due to I/O error on xvda2 [ 3.801755] Aborting journal on device xvda2.

This can be seen in /proc/drbd (by "wo:f, meaning flush, the next method drbd chooses after barrier): 3: cs:Connected ro:Primary/Secondary ds:UpToDate/UpToDate C r---- ns:2160152 nr:520204 dw:2680344 dr:2678107 al:3549 bm:9183 lo:0 pe:0 ua:0 ap:0 ep:1 wo:f oos:0 And on the other host: 3: cs:Connected ro:Secondary/Primary ds:UpToDate/UpToDate C r---- ns:0 nr:2160152 dw:2160152 dr:0 al:0 bm:8052 lo:0 pe:0 ua:0 ap:0 ep:1 wo:f oos:0 I also enabled the option disable_sendpage, as per the drbd docs: cat /sys/module/drbd/parameters/disable_sendpage Y I also tried adding barriers=0 to fstab as mount option. Still it sometimes says: [ 58.603896] blkfront: barrier: write xvda2 op failed [ 58.603903] blkfront: xvda2: barrier or flush: disabled I don't even know if ext3 has a nobarrier option. And, because only one of my storage systems is battery backed, it would not be smart anyway. Why does it still compain about barriers when I disabled that?

The secondary is software RAID1. Isn't DRBD+Xen widely used? With these problems, it's not going to work.

  • I can't get SetSystemTime to work in Windows Vista using C# with Interop (P/Invoke).

    - by Andrew
    Hi, I'm having a hard time getting SetSystemTime working in my C# code. SetSystemtime is a kernel32.dll function. I'm using P/invoke (interop) to call it. SetSystemtime returns false and the error is "Invalid Parameter". I've posted the code below. I stress that GetSystemTime works just fine. I've tested this on Vista and Windows 7. Based on some newsgroup postings I've seen I have turned off UAC. No difference. I have done some searching for this problem. I found this link: http://groups.google.com.tw/group/microsoft.public.dotnet.framework.interop/browse_thread/thread/805fa8603b00c267 where the problem is reported but no resolution seems to be found. Notice that UAC is also mentioned but I'm not sure this is the problem. Also notice that this gentleman gets no actual Win32Error. Can someone try my code on XP? Can someone tell me what I'm doing wrong and how to fix it. If the answer is to somehow change permission settings programatically, I'd need an example. I would have thought turning off UAC should cover that though. I'm not required to use this particular way (SetSystemTime). I'm just trying to introduce some "clock drift" to stress test something. If there's another way to do it, please tell me. Frankly, I'm surprised I need to use Interop to change the system time. I would have thought there is a .NET method. Thank you very much for any help or ideas. Andrew Code: using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Runtime.InteropServices; namespace SystemTimeInteropTest { class Program { #region ClockDriftSetup [StructLayout(LayoutKind.Sequential)] public struct SystemTime { [MarshalAs(UnmanagedType.U2)] public short Year; [MarshalAs(UnmanagedType.U2)] public short Month; [MarshalAs(UnmanagedType.U2)] public short DayOfWeek; [MarshalAs(UnmanagedType.U2)] public short Day; [MarshalAs(UnmanagedType.U2)] public short Hour; [MarshalAs(UnmanagedType.U2)] public short Minute; [MarshalAs(UnmanagedType.U2)] public short Second; [MarshalAs(UnmanagedType.U2)] public short Milliseconds; } [DllImport("kernel32.dll")] public static extern void GetLocalTime( out SystemTime systemTime); [DllImport("kernel32.dll")] public static extern void GetSystemTime( out SystemTime systemTime); [DllImport("kernel32.dll", SetLastError = true)] public static extern bool SetSystemTime( ref SystemTime systemTime); //[DllImport("kernel32.dll", SetLastError = true)] //public static extern bool SetLocalTime( //ref SystemTime systemTime); [System.Runtime.InteropServices.DllImportAttribute("kernel32.dll", EntryPoint = "SetLocalTime")] [return: System.Runtime.InteropServices.MarshalAsAttribute(System.Runtime.InteropServices.UnmanagedType.Bool)] public static extern bool SetLocalTime([InAttribute()] ref SystemTime lpSystemTime); #endregion ClockDriftSetup static void Main(string[] args) { try { SystemTime sysTime; GetSystemTime(out sysTime); sysTime.Milliseconds += (short)80; sysTime.Second += (short)3000; bool bResult = SetSystemTime(ref sysTime); if (bResult == false) throw new System.ComponentModel.Win32Exception(); } catch (Exception ex) { Console.WriteLine("Drift Error: " + ex.Message); } } } }

  • BasicAuthProvider in ServiceStack

    - by Per
    I've got an issue with the BasicAuthProvider in ServiceStack. POST-ing to the CredentialsAuthProvider (/auth/credentials) is working fine. The problem is that when GET-ing (in Chrome): http://foo:pwd@localhost:81/tag/string/list the following is the result Handler for Request not found: Request.HttpMethod: GET Request.HttpMethod: GET Request.PathInfo: /login Request.QueryString: System.Collections.Specialized.NameValueCollection Request.RawUrl: /login?redirect=http%3a%2f%2flocalhost%3a81%2ftag%2fstring%2flist which tells me that it redirected me to /login instead of serving the /tag/... request. Here's the entire code for my AppHost: public class AppHost : AppHostHttpListenerBase, IMessageSubscriber { private ITagProvider myTagProvider; private IMessageSender mySender; private const string UserName = "foo"; private const string Password = "pwd"; public AppHost( TagConfig config, IMessageSender sender ) : base( "BM App Host", typeof( AppHost ).Assembly ) { myTagProvider = new TagProvider( config ); mySender = sender; } public class CustomUserSession : AuthUserSession { public override void OnAuthenticated( IServiceBase authService, IAuthSession session, IOAuthTokens tokens, System.Collections.Generic.Dictionary<string, string> authInfo ) { authService.RequestContext.Get<IHttpRequest>().SaveSession( session ); } } public override void Configure( Funq.Container container ) { Plugins.Add( new MetadataFeature() ); container.Register<BeyondMeasure.WebAPI.Services.Tags.ITagProvider>( myTagProvider ); container.Register<IMessageSender>( mySender ); Plugins.Add( new AuthFeature( () => new CustomUserSession(), new AuthProvider[] { new CredentialsAuthProvider(), //HTML Form post of UserName/Password credentials new BasicAuthProvider(), //Sign-in with Basic Auth } ) ); container.Register<ICacheClient>( new MemoryCacheClient() ); var userRep = new InMemoryAuthRepository(); container.Register<IUserAuthRepository>( userRep ); string hash; string salt; new SaltedHash().GetHashAndSaltString( Password, out hash, out salt ); // Create test user userRep.CreateUserAuth( new UserAuth { Id = 1, DisplayName = "DisplayName", Email = "[email protected]", UserName = UserName, FirstName = "FirstName", LastName = "LastName", PasswordHash = hash, Salt = salt, }, Password ); } } Could someone please tell me what I'm doing wrong with either the SS configuration or how I am calling the service, i.e. why does it not accept the supplied user/pwd? Update1: Request/Response captured in Fiddler2when only BasicAuthProvider is used. No Auth header sent in the request, but also no Auth header in the response.

  • WCF and Firewalls

    - by Amitd
    Hi guys, As a part of learning WCF, I was trying to use a simple WCF client-server code . http://weblogs.asp.net/ralfw/archive/2007/04/14/a-truely-simple-example-to-get-started-with-wcf.aspx but I'm facing strange issues.I was trying out the following. Client(My) IP address is : 192.168.2.5 (internal behind firewall) Server IP address is : 192.168.50.30 port : 9050 (internal behind firewall) Servers LIVE/External IP (on internet ) : 121.225.xx.xx (accessible from internet) When I specify the above I.P address of server(192.168.50.30), the client connects successfully and can call servers methods. Now suppose if I want to give my friend (outside network/on internet) the client with server's live I.P, i get an ENDPOINTNOTFOUND exceptions. Surprisingly if I run the above client specifying LIVE IP(121.225.xx.xx) of server i also get the same exception. I tried to debug the problem but haven't found anything. Is it a problem with the company firewall not forwarding my request? or is it a problem with the server or client . Is something needed to be added to the server/client to overcome the same problem? Or are there any settings on the firewall that need to be changed like port forwarding? (our network admin has configured the port to be accessible from the internet.) is it a authentication issue? Code is available at . http://www.ralfw.de/weblog/wcfsimple.txt http://weblogs.asp.net/ralfw/archive/2007/04/14/a-truely-simple-example-to-get-started-with-wcf.aspx i have just separated the client and server part in separate assemblies.rest is same. using System; using System.Collections.Generic; using System.Text; using System.ServiceModel; namespace WCFSimple.Contract { [ServiceContract] public interface IService { [OperationContract] string Ping(string name); } } namespace WCFSimple.Server { [ServiceBehavior(InstanceContextMode = InstanceContextMode.PerCall)] class ServiceImplementation : WCFSimple.Contract.IService { #region IService Members public string Ping(string name) { Console.WriteLine("SERVER - Processing Ping('{0}')", name); return "Hello, " + name; } #endregion } public class Program { private static System.Threading.AutoResetEvent stopFlag = new System.Threading.AutoResetEvent(false); public static void Main() { ServiceHost svh = new ServiceHost(typeof(ServiceImplementation)); svh.AddServiceEndpoint( typeof(WCFSimple.Contract.IService), new NetTcpBinding(), "net.tcp://localhost:8000"); svh.Open(); Console.WriteLine("SERVER - Running..."); stopFlag.WaitOne(); Console.WriteLine("SERVER - Shutting down..."); svh.Close(); Console.WriteLine("SERVER - Shut down!"); } public static void Stop() { stopFlag.Set(); } } } namespace WCFSimple { class Program { static void Main(string[] args) { Console.WriteLine("WCF Simple Demo"); // start server System.Threading.Thread thServer = new System.Threading.Thread(WCFSimple.Server.Program.Main); thServer.IsBackground = true; thServer.Start(); System.Threading.Thread.Sleep(1000); // wait for server to start up // run client ChannelFactory<WCFSimple.Contract.IService> scf; scf = new ChannelFactory<WCFSimple.Contract.IService>( new NetTcpBinding(), "net.tcp://localhost:8000"); WCFSimple.Contract.IService s; s = scf.CreateChannel(); while (true) { Console.Write("CLIENT - Name: "); string name = Console.ReadLine(); if (name == "") break; string response = s.Ping(name); Console.WriteLine("CLIENT - Response from service: " + response); } (s as ICommunicationObject).Close(); // shutdown server WCFSimple.Server.Program.Stop(); thServer.Join(); } } } Any help?
