  • Uploading multiple images through Tumblr API

    - by Joseph Carrington
    I have about 300 images I want to upload to my new Tumblr account, becuase my old wordpress site got hacked and I no longer wish to use wordpress. I uploaded one image a day for 300 days, and I'd like to be able to take these images and upload them to my tumblr site using the api. The images are currently local, stored in /images/. They all have the date they were uploaded as the first ten characters of the filename, (01-01-2009-filename.png) and I went to send this date parameter along as well. I want to be able to see the progress of the script by outputting the responses from the API to my error_log. Here is what I have so far, based on the tumblr api page. // Authorization info $tumblr_email = '[email protected]'; $tumblr_password = 'password'; // Tumblr script parameters $source_directory = "images/"; // For each file, assign the file to a pointer here's the first stumbling block. How do I get all of the images in the directory and loop through them? Once I have a for or while loop set up I assume this is the next step $post_data = fopen(dir(__FILE__) . $source_directory . $current_image, 'r'); $post_date = substr($current_image, 0, 10); // Data for new record $post_type = 'photo'; // Prepare POST request $request_data = http_build_query( array( 'email' => $tumblr_email, 'password' => $tumblr_password, 'type' => $post_type, 'data' => $post_data, 'date' => $post_date, 'generator' => 'Multi-file uploader' ) ); // Send the POST request (with cURL) $c = curl_init('http://www.tumblr.com/api/write'); curl_setopt($c, CURLOPT_POST, true); curl_setopt($c, CURLOPT_POSTFIELDS, $request_data); curl_setopt($c, CURLOPT_RETURNTRANSFER, true); $result = curl_exec($c); $status = curl_getinfo($c, CURLINFO_HTTP_CODE); curl_close($c); // Output response to error_log error_log($result); So, I'm stuck on how to use PHP to read a file directory, loop through each of the files, and do things to the name / with the file itself. I also need to know how to set the data parameter, as in choosing multi-part / formdata. I also don't know anything about cURL.

  • Android:How to display images from the in a ListView?

    - by Maxood
    Android:How to display images from the web in a ListView?I have the following code to display image from a URL in an ImageView: import java.io.IOException; import java.io.InputStream; import java.net.HttpURLConnection; import java.net.URL; import java.net.URLConnection; import android.app.ListActivity; import android.graphics.Bitmap; import android.graphics.BitmapFactory; import android.os.Bundle; import android.widget.ImageView; public class HttpImgDownload extends ListActivity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); Bitmap bitmap = // DownloadImage( // "http://www.streetcar.org/mim/cable/images/cable-01.jpg"); DownloadImage( "http://s.twimg.com/a/1258674567/images/default_profile_3_normal.png"); ImageView img = (ImageView) findViewById(R.id.img); img.setImageBitmap(bitmap); } private InputStream OpenHttpConnection(String urlString) throws IOException { InputStream in = null; int response = -1; URL url = new URL(urlString); URLConnection conn = url.openConnection(); if (!(conn instanceof HttpURLConnection)) throw new IOException("Not an HTTP connection"); try{ HttpURLConnection httpConn = (HttpURLConnection) conn; httpConn.setAllowUserInteraction(false); httpConn.setInstanceFollowRedirects(true); httpConn.setRequestMethod("GET"); httpConn.connect(); response = httpConn.getResponseCode(); if (response == HttpURLConnection.HTTP_OK) { in = httpConn.getInputStream(); } } catch (Exception ex) { throw new IOException("Error connecting"); } return in; } private Bitmap DownloadImage(String URL) { Bitmap bitmap = null; InputStream in = null; try { in = OpenHttpConnection(URL); bitmap = BitmapFactory.decodeStream(in); in.close(); } catch (IOException e1) { // TODO Auto-generated catch block e1.printStackTrace(); } return bitmap; } } Now how can i display images in an array in a listview?

  • Custom DataAnnotation attribute with datastore access in ASP.NET MVC 2

    - by mare
    I have my application designed with Repository pattern implemented and my code prepared for optional dependency injection in future, if we need to support another datastore. I want to create a custom validation attribute for my content objects. This attribute should perform some kind of datastore lookup. For instance, I need my content to have unique slugs. To check if a Slug already exist, I want to use custom DataAnnotation attribute in my Base content object (instead of manually checking if a slug exists each time in my controller's Insert actions). Attribute logic would do the validation. So far I have come up with this: public class UniqueSlugAttribute : ValidationAttribute { private readonly IContentRepository _repository; public UniqueSlugAttribute(ContentType contentType) { _repository = new XmlContentRepository(contentType); } public override bool IsValid(object value) { if (string.IsNullOrWhiteSpace(value.ToString())) { return false; } string slug = value.ToString(); if(_repository.IsUniqueSlug(slug)) return true; return false; } } part of my Base content class: ... [DataMember] public ContentType ContentType1 { get; set; } [DataMember] [Required(ErrorMessageResourceType = typeof (Localize), ErrorMessageResourceName = "Validation_SlugIsBlank")] [UniqueSlug(ContentType1)] public string Slug { get { return _slug; } set { if (!string.IsNullOrEmpty(value)) _slug = Utility.RemoveIllegalCharacters(value); } } ... There's an error in line [UniqueSlug(ContentType1)] saying: "An attribute argument must be a constant expression, typeof expression or array creation expression of an attribute parameter type." Let me explain that I need to provide the ContentType1 parameter to the Constructor of UniqueSlug class because I use it in my data provider. It is actually the same error that appears if you try do to this on the built-in Required attribute: [Required(ErrorMessageResourceType = typeof (Localize), ErrorMessageResourceName = Resources.Localize.SlugRequired] It does not allow us to set it to dynamic content. In the first case ContentType1 gets known at runtime, in the second case the Resources.Localize.SlugRequired also gets known at runtime (because the Culture settings are assigned at runtime). This is really annoying and makes so many things and implementation scenarios impossible. So, my first question is, how to get rid of this error? The second question I have, is whether you think that I should redesign my validation code in any way?

  • Android: get current location from best available provider

    - by AP257
    Hi all, I have some Android code that needs to get the best available location QUICKLY, from GPS, network or whatever is available. Accuracy is less important than speed. Getting the best available location is surely a really standard task. Yet I can't find any code to demonstrate it. The Android location code expects you to specify criteria, register for updates, and wait - which is fine if you have detailed criteria and don't mind waiting around. But my app needs to work a bit more like the Maps app does when it first locates you - work from any available provider, and just check the location isn't wildly out of date or null. I've attempted to roll my own code to do this, but am having problems. (It's inside an IntentService where an upload happens, if that makes any difference. I've included all the code for info.) What's wrong with this code? @Override protected void onHandleIntent(Intent arg0) { testProviders(); doUpload(); } private boolean doUpload() { int j = 0; // check if we have accurate location data yet - wait up to 30 seconds while (j < 30) { if ((latString == "") || (lonString == "")) { Log.d(LOG_TAG, "latlng null"); Thread.sleep(1000); j++; } else { Log.d(LOG_TAG, "found lat " + latString + " and lon " + lonString); break; } //do the upload here anyway, with or without location data //[code removed for brevity] } public boolean testProviders() { Log.e(LOG_TAG, "testProviders"); String location_context = Context.LOCATION_SERVICE; locationmanager = (LocationManager) getSystemService(location_context); List<String> providers = locationmanager.getProviders(true); for (String provider : providers) { Log.e(LOG_TAG, "registering provider " + provider); listener = new LocationListener() { public void onLocationChanged(Location location) { // keep checking the location - until we have // what we need //if (!checkLoc(location)) { Log.e(LOG_TAG, "onLocationChanged"); locationDetermined = checkLoc(location); //} } public void onProviderDisabled(String provider) { } public void onProviderEnabled(String provider) { } public void onStatusChanged(String provider, int status, Bundle extras) { } }; locationmanager.requestLocationUpdates(provider, 0, 0, listener); } Log.e(LOG_TAG, "getting updates"); return true; } private boolean checkLoc(Location location) { float tempAccuracy = location.getAccuracy(); int locAccuracy = (int) tempAccuracy; Log.d(LOG_TAG, "locAccuracy = " + locAccuracy); if ((locAccuracy != 0) && (locAccuracy < LOCATION_ACCURACY)) { latitude = location.getLatitude(); longitude = location.getLongitude(); latString = latitude.toString(); lonString = longitude.toString(); return true; } return false; } public void removeListeners() { // Log.e(LOG_TAG, "removeListeners"); if ((locationmanager != null) && (listener != null)) { locationmanager.removeUpdates(listener); } locationmanager = null; // Log.d(LOG_TAG, "Removed " + listener.toString()); } @Override public void onDestroy() { super.onDestroy(); removeListeners(); } Unfortunately, this finds the network provider, but only ever outputs latlng null 30 times - it never seems to get a location at all. I never even get a log statement of locationChanged. It's funny, because from ddms I can see output like: NetworkLocationProvider: onCellLocationChanged [305,8580] NetworkLocationProvider: getNetworkLocation(): returning cache location with accuracy 75.0 seeming to suggest that the network provider does have some location info after all, I'm just not getting at it. Can anyone help? I think working example code would be a useful resource for the Android/StackOverflow community.

  • Deploying WCF Tutorial App on IIS7: "The type could not be found"

    - by Jimmy
    Hello, I've been trying to follow this tutorial for deploying a WCF sample to IIS . I can't get it to work. This is a hosted site, but I do have IIS Manager access to the server. However, in step 2 of the tutorial, I can't "create a new IIS application that is physically located in this application directory". I can't seem to find a menu item, context menu item, or what not to create a new application. I've been right-clicking everywhere like crazy and still can't figure out how to create a new app. I suppose that's probably the root issue, but I tried a few other things (described below) just in case that actually is not the issue. Here is a picture of what I see in IIS Manager, in case my words don't do it justice: This is "deployed" at http://test.com.cws1.my-hosting-panel.com/IISHostedCalcService/Service.svc . The error says: The type 'Microsoft.ServiceModel.Samples.CalculatorService', provided as the Service attribute value in the ServiceHost directive, or provided in the configuration element system.serviceModel/serviceHostingEnvironment/serviceActivations could not be found. I also tried to create a virtual dir (IISHostedCalc) in dotnetpanel that points to IISHostedCalcService . When I navigate to http://test.com.cws1.my-hosting-panel.com/IISHostedCalc/Service.svc , then there is a different error: This collection already contains an address with scheme http. There can be at most one address per scheme in this collection. Interestingly enough, if I click on View Applications, it seems like the virtual directory is an application (see image below)... although, as per the error message above, it doesn't work. As per the tutorial, there was no compiling involved; I just dropped the files on the server as follow inside the folder IISHostedCalcService: service.svc Web.config <dir: App_Code> Service.cs service.svc contains: <%@ServiceHost language=c# Debug="true" Service="Microsoft.ServiceModel.Samples.CalculatorService"%> (I tried with quotes around the c# attribute, as this looks a little strange without quotes, but it made no difference) Web.config contains: <?xml version="1.0" encoding="utf-8" ?> <configuration> <system.serviceModel> <services> <service name="Microsoft.ServiceModel.Samples.CalculatorService"> <!-- This endpoint is exposed at the base address provided by host: http://localhost/servicemodelsamples/service.svc --> <endpoint address="" binding="wsHttpBinding" contract="Microsoft.ServiceModel.Samples.ICalculator" /> <!-- The mex endpoint is explosed at http://localhost/servicemodelsamples/service.svc/mex --> <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" /> </service> </services> </system.serviceModel> <system.web> <customErrors mode="Off"/> </system.web> </configuration> Service.cs contains: using System; using System.ServiceModel; namespace Microsoft.ServiceModel.Samples { [ServiceContract] public interface ICalculator { [OperationContract] double Add(double n1, double n2); [OperationContract] double Subtract(double n1, double n2); [OperationContract] double Multiply(double n1, double n2); [OperationContract] double Divide(double n1, double n2); } public class CalculatorService : ICalculator { public double Add(double n1, double n2) { return n1 + n2; } public double Subtract(double n1, double n2) { return n1 - n2; } public double Multiply(double n1, double n2) { return n1 * n2; } public double Divide(double n1, double n2) { return n1 / n2; } } }

  • Java, Jacob and Microsoft Outlook events: Receiving "Can't find event iid" Error

    - by Adam Paynter
    I am writing a Java program that interacts with Microsoft Outlook using the Jacob library (bridges COM and Java). This program creates a new MailItem, displaying its Inspector window to the user. I wish to subscribe to the inspector's Close event to know when the user is finished editing their mail item. To subscribe to the event, I followed the instructions in Jacob's documentation (about 2⁄3 down the page): The current [event] model is conceptually similar to the Visual Basic WithEvents construct. Basically, I provide a class called com.jacob.com.DispatchEvents which has a constructor that takes a source object (of type com.jacob.com.Dispatch) and a target object (of any type). The source object is queried for its IConnectionPointContainer interface and I attempt to obtain an IConnectionPoint for its default source interface (which I obtain from IProvideClassInfo). At the same time, I also create a mapping of DISPID's for the default source interface to the actual method names. I then use the method names to get jmethodID handles from the target Java object. All event methods currently must have the same signature: one argument which is a Java array of Variants, and a void return type. Here is my InspectorEventHandler class, conforming to Jacob's documentation: public class InspectorEventHandler { public void Activate(Variant[] arguments) { } public void BeforeMaximize(Variant[] arguments) { } public void BeforeMinimize(Variant[] arguments) { } public void BeforeMove(Variant[] arguments) { } public void BeforeSize(Variant[] arguments) { } public void Close(Variant[] arguments) { System.out.println("Closing"); } public void Deactivate(Variant[] arguments) { } public void PageChange(Variant[] arguments) { } } And here is how I subscribe to the events using this InspectorEventHandler class: Object outlook = new ActiveXComponent("Outlook.Application"); Object mailItem = Dispatch.call(outlook, "CreateItem", 0).getDispatch(); Object inspector = Dispatch.get(mailItem, "GetInspector").getDispatch(); InspectorEventHandler eventHandler = new InspectorEventHandler(); // This supposedly registers eventHandler with the inspector new DispatchEvents((Dispatch) inspector, eventHandler); However, the last line fails with the following exception: Exception in thread "main" com.jacob.com.ComFailException: Can't find event iid at com.jacob.com.DispatchEvents.init(Native Method) at com.jacob.com.DispatchEvents.(DispatchEvents.java) at cake.CakeApplication.run(CakeApplication.java:30) at cake.CakeApplication.main(CakeApplication.java:15) couldn't get IProvideClassInfo According to Google, a few others have also received this error. Unfortunately, none of them have received an answer. I am using version 1.7 of the Jacob library, which claims to prevent this problem: Version 1.7 also includes code to read the type library directly from the progid. This makes it possible to work with all the Microsoft Office application events, as well as IE5 events. For an example see the samples/test/IETest.java example. I noticed that the aforementioned IETest.java file subscribes to events like this: new DispatchEvents((Dispatch) ieo, ieE,"InternetExplorer.Application.1"); Therefore, I tried subscribing to my events in a similar manner: new DispatchEvents((Dispatch) inspector, eventHandler, "Outlook.Application"); new DispatchEvents((Dispatch) inspector, eventHandler, "Outlook.Application.1"); new DispatchEvents((Dispatch) inspector, eventHandler, "Outlook.Application.12"); All these attempts failed with the same error.

  • Doctrine 2 Cannot find entites

  • Game loop and time tracking

    - by David Brown
    Maybe I'm just an idiot, but I've been trying to implement a game loop all day and it's just not clicking. I've read literally every article I could find on Google, but the problem is that they all use different timing mechanisms, which makes them difficult to apply to my particular situation (some use milliseconds, other use ticks, etc). Basically, I have a Clock object that updates each time the game loop executes. internal class Clock { public static long Timestamp { get { return Stopwatch.GetTimestamp(); } } public static long Frequency { get { return Stopwatch.Frequency; } } private long _startTime; private long _lastTime; private TimeSpan _totalTime; private TimeSpan _elapsedTime; /// <summary> /// The amount of time that has passed since the first step. /// </summary> public TimeSpan TotalTime { get { return _totalTime; } } /// <summary> /// The amount of time that has passed since the last step. /// </summary> public TimeSpan ElapsedTime { get { return _elapsedTime; } } public Clock() { Reset(); } public void Reset() { _startTime = Timestamp; _lastTime = 0; _totalTime = TimeSpan.Zero; _elapsedTime = TimeSpan.Zero; } public void Tick() { long currentTime = Timestamp; if (_lastTime == 0) _lastTime = currentTime; _totalTime = TimestampToTimeSpan(currentTime - _startTime); _elapsedTime = TimestampToTimeSpan(currentTime - _lastTime); _lastTime = currentTime; } public static TimeSpan TimestampToTimeSpan(long timestamp) { return TimeSpan.FromTicks( (timestamp * TimeSpan.TicksPerSecond) / Frequency); } } I based most of that on the XNA GameClock, but it's greatly simplified. Then, I have a Time class which holds various times that the Update and Draw methods need to know. public class Time { public TimeSpan ElapsedVirtualTime { get; internal set; } public TimeSpan ElapsedRealTime { get; internal set; } public TimeSpan TotalVirtualTime { get; internal set; } public TimeSpan TotalRealTime { get; internal set; } internal Time() { } internal Time(TimeSpan elapsedVirtualTime, TimeSpan elapsedRealTime, TimeSpan totalVirutalTime, TimeSpan totalRealTime) { ElapsedVirtualTime = elapsedVirtualTime; ElapsedRealTime = elapsedRealTime; TotalVirtualTime = totalVirutalTime; TotalRealTime = totalRealTime; } } My main class keeps a single instance of Time, which it should constantly update during the game loop. So far, I have this: private static void Loop() { do { Clock.Tick(); Time.TotalRealTime = Clock.TotalTime; Time.ElapsedRealTime = Clock.ElapsedTime; InternalUpdate(Time); InternalDraw(Time); } while (!_exitRequested); } The real time properties of the time class turn out great. Now I'd like to get a proper update/draw loop working so that the state is updated a variable number of times per frame, but at a fixed timestep. At the same time, the Time.TotalVirtualTime and Time.ElapsedVirtualTime should be updated accordingly. In addition, I intend for this to support multiplayer in the future, in case that makes any difference to the design of the game loop. Any tips or examples on how I could go about implementing this (aside from links to articles)?

  • Android "Trying to use recycled bitmap" error?

    - by Mike
    Hi all, I am running into a problem with bitmaps on an Android application I am working on. What is suppose to happen is that the application downloads images from a website, saves them to the device, loads them into memory as bitmaps into an arraylist, and displays them to the user. This all works fine when the application is first started. However, I have added a refresh option for the user where the images are deleted, and the process outlined above starts all over. My problem: By using the refresh option the old images were still in memory and I would quickly get OutOfMemoryErrors. Thus, if the images are being refreshed, I had it run through the arraylist and recycle the old images. However, when the application goes to load the new images into the arraylist, it crashes with a "Trying to use recycled bitmap" error. As far as I understand it, recycling a bitmap destroys the bitmap and frees up its memory for other objects. If I want to use the bitmap again, it has to be reinitialized. I believe that I am doing this when the new files are loaded into the arraylist, but something is still wrong. Any help is greatly appreciated as this is very frustrating. The problem code is below. Thank you! public void fillUI(final int refresh) { // Recycle the images to avoid memory leaks if(refresh==1) { for(int x=0; x<images.size(); x++) images.get(x).recycle(); images.clear(); selImage=-1; // Reset the selected image variable } final ProgressDialog progressDialog = ProgressDialog.show(this, null, this.getString(R.string.loadingImages)); // Create the array with the image bitmaps in it new Thread(new Runnable() { public void run() { Looper.prepare(); File[] fileList = new File("/data/data/[package name]/files/").listFiles(); if(fileList!=null) { for(int x=0; x<fileList.length; x++) { try { images.add(BitmapFactory.decodeFile("/data/data/[package name]/files/" + fileList[x].getName())); } catch (OutOfMemoryError ome) { Log.i(LOG_FILE, "out of memory again :("); } } Collections.reverse(images); } fillUiHandler.sendEmptyMessage(0); } }).start(); fillUiHandler = new Handler() { public void handleMessage(Message msg) { progressDialog.dismiss(); } }; }

  • VS2010 Assembly Load Error

    - by Nate
    I am getting the following error when I try to build an ASP.NET 4 project in Visual Studio 2010: "Could not load file or assembly 'file:///C:\Dev\project\trunk\bin\Elmah.dll' or one of its dependencies. Operation is not supported. (Exception from HRESULT: 0x80131515)". I have verified that the dll does, in fact, exist, and is getting copied to the bin folder correctly. I have also tried removing and then re-adding the reference to the project. The build only fails when I switch the Solution Configuration to "Release".

  • HTTP Bad Request error when requesting a WCF service contract

    - by Enrico Campidoglio
    I have a WCF service with the following configuration: <system.serviceModel> <behaviors> <serviceBehaviors> <behavior name="MetadataEnabled"> <serviceDebug includeExceptionDetailInFaults="true" /> <serviceMetadata httpGetEnabled="true" /> </behavior> </serviceBehaviors> </behaviors> <services> <service behaviorConfiguration="MetadataEnabled" name="MyNamespace.MyService"> <endpoint name="BasicHttp" address="" binding="basicHttpBinding" contract="MyNamespace.IMyServiceContract" /> <endpoint name="MetadataHttp" address="contract" binding="mexHttpBinding" contract="IMetadataExchange" /> <host> <baseAddresses> <add baseAddress="http://localhost/myservice" /> </baseAddresses> </host> </service> </services> </system.serviceModel> When hosting the service in the WcfSvcHost.exe process, if I browse to the URL: http://localhost/myservice/contract where the service metadata is available I get an HTTP 400 Bad Request error. By inspecting the WCF logs I found out that an System.Xml.XmlException exception is being thrown with the message: "The body of the message cannot be read because it is empty."Here is an extract of the log file: <Exception> <ExceptionType> System.ServiceModel.ProtocolException, System.ServiceModel, Version=3.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089 </ExceptionType> <Message>There is a problem with the XML that was received from the network.

  • UITableView : crash when adding a section footer view in empty section

    - by Supernico
    Hi everyone, This is the first time I ask a question here, but I have to say this site has been a tremendous help for me over the last couple months (iphone-dev-wise), and I thank you for that. However, I didn't find any solution for this problem I'm having: I have a UITableView with 2 sections, and no rows when the app is launched for the first time. The user can fill the sections later on as he wishes (the content is not relevant here). The UITableView looks good when filled with rows, but looks pretty ugly when there is none (the 2 header sections are stuck together with no white space in between). That is why I'd like to add a nice "No row" view in between when there is no row. I used viewForFooterInSection: - (CGFloat)tableView:(UITableView *)tableView heightForFooterInSection:(NSInteger)section { if(section == 0) { if([firstSectionArray count] == 0) return 44; else return 0; } return 0; } - (UIView *)tableView:(UITableView *)tableView viewForFooterInSection:(NSInteger)section{ if(section == 0) { UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(200, 10, 50, 44)]; label.backgroundColor = [UIColor clearColor]; label.textColor = [UIColor colorWithWhite:0.6 alpha:1.0]; label.textAlignment = UITextAlignmentCenter; label.lineBreakMode = UILineBreakModeWordWrap; label.numberOfLines = 0; label.text = @"No row"; return [label autorelease]; } return nil; } - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView { return 2; } - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { if(section == 0) { return [firstSectionArray count]; } return [secondSectionArray count]; } This works great : the footer view appears only when there is no row in section 0. But my app crashes when I enter edit mode and delete the last row in section 0: Assertion failure in -[UIViewAnimation initWithView:indexPath:endRect:endAlpha:startFraction:endFraction:curve:animateFromCurrentPosition:shouldDeleteAfterAnimation:editing:] Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Cell animation stop fraction must be greater than start fraction' This does not happen when there are several rows in section 0. It only happens when there is only one row left. Here's the code for edit mode: - (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath { // If row is deleted, remove it from the list. if (editingStyle == UITableViewCellEditingStyleDelete) { // Find the book at the deleted row, and remove from application delegate's array. if(indexPath.section == 0) { [firstSectionArray removeObjectAtIndex:indexPath.row]; } else { [secondSectionArray removeObjectAtIndex:indexPath.row]; } // Animate the deletion from the table. [tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationBottom]; [tableView reloadData]; } } Does anyone have any idea why this is happening? Thanks

  • jQuery load Google Visualization API with AJAX

    - by Curro
    Hello. There is an issue that I cannot solve, I've been looking a lot in the internet but found nothing. I have this JavaScript that is used to do an Ajax request by PHP. When the request is done, it calls a function that uses the Google Visualization API to draw an annotatedtimeline to present the data. The script works great without AJAX, if I do everything inline it works great, but when I try to do it with AJAX it doesn't work!!! The error that I get is in the declaration of the "data" DataTable, in the Google Chrome Developer Tools I get a Uncaught TypeError: Cannot read property 'DataTable' of undefined. When the script gets to the error, everything on the page is cleared, it just shows a blank page. So I don't know how to make it work. Please help Thanks in advance $(document).ready(function(){ // Get TIER1Tickets $("#divTendency").addClass("loading"); $.ajax({ type: "POST", url: "getTIER1Tickets.php", data: "", success: function(html){ // Succesful, load visualization API and send data google.load('visualization', '1', {'packages': ['annotatedtimeline']}); google.setOnLoadCallback(drawData(html)); } }); }); function drawData(response){ $("#divTendency").removeClass("loading"); // Data comes from PHP like: <CSV ticket count for each day>*<CSV dates for ticket counts>*<total number of days counted> // So it has to be split first by * then by , var dataArray = response.split("*"); var dataTickets = dataArray[0]; var dataDates = dataArray[1]; var dataCount = dataArray[2]; // The comma separation now splits the ticket counts and the dates var dataTicketArray = dataTickets.split(","); var dataDatesArray = dataDates.split(","); // Visualization data var data = new google.visualization.DataTable(); data.addColumn('date', 'Date'); data.addColumn('number', 'Tickets'); data.addRows(dataCount); var dateSplit = new Array(); for(var i = 0 ; i < dataCount ; i++){ // Separating the data because must be entered as "new Date(YYYY,M,D)" dateSplit = dataDatesArray[i].split("-"); data.setValue(i, 0, new Date(dateSplit[2],dateSplit[1],dateSplit[0])); data.setValue(i, 1, parseInt(dataTicketArray[i])); } var annotatedtimeline = new google.visualization.AnnotatedTimeLine(document.getElementById('divTendency')); annotatedtimeline.draw(data, {displayAnnotations: true}); }

  • delta-dictionary/dictionary with revision awareness in python?

    - by shabbychef
    I am looking to create a dictionary with 'roll-back' capabilities in python. The dictionary would start with a revision number of 0, and the revision would be bumped up only by explicit method call. I do not need to delete keys, only add and update key,value pairs, and then roll back. I will never need to 'roll forward', that is, when rolling the dictionary back, all the newer revisions can be discarded, and I can start re-reving up again. thus I want behaviour like: >>> rr = rev_dictionary() >>> rr.rev 0 >>> rr["a"] = 17 >>> rr[('b',23)] = 'foo' >>> rr["a"] 17 >>> rr.rev 0 >>> rr.roll_rev() >>> rr.rev 1 >>> rr["a"] 17 >>> rr["a"] = 0 >>> rr["a"] 0 >>> rr[('b',23)] 'foo' >>> rr.roll_to(0) >>> rr.rev 0 >>> rr["a"] 17 >>> rr.roll_to(1) Exception ... Just to be clear, the state associated with a revision is the state of the dictionary just prior to the roll_rev() method call. thus if I can alter the value associated with a key several times 'within' a revision, and only have the last one remembered. I would like a fairly memory-efficient implementation of this: the memory usage should be proportional to the deltas. Thus simply having a list of copies of the dictionary will not scale for my problem. One should assume the keys are in the tens of thousands, and the revisions are in the hundreds of thousands. We can assume the values are immutable, but need not be numeric. For the case where the values are e.g. integers, there is a fairly straightforward implementation (have a list of dictionaries of the numerical delta from revision to revision). I am not sure how to turn this into the general form. Maybe bootstrap the integer version and add on an array of values? all help appreciated.

  • Implementing touch-based rotation in cocoa touch

    - by ewoo
    I am wondering what is the best way to implement rotation-based dragging movements in my iPhone application. I have a UIView that I wish to rotate around its centre, when the users finger is touch the view and they move it. Think of it like a dial that needs to be adjusted with the finger. The basic question comes down to: 1) Should I remember the initial angle and transform when touchesBegan is called, and then every time touchesMoved is called apply a new transform to the view based on the current position of the finger, e.g., something like: - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { UITouch *touch = [touches anyObject]; CGPoint currentPoint = [touch locationInView:self]; //current position of touch if (([touch view] == self) && [Utility getDistance:currentPoint toPoint:self.middle] <= ROTATE_RADIUS //middle is centre of view && [Utility getDistance:currentPoint toPoint:self.middle] >= MOVE_RADIUS) { //will be rotation gesture //remember state of view at beginning of touch CGPoint top = CGPointMake(self.middle.x, 0); self.initialTouch = currentPoint; self.initialAngle = angleBetweenLines(self.middle, top, self.middle, currentPoint); self.initialTransform = self.transform; } } - (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event{ UITouch *touch = [touches anyObject]; CGPoint currentPoint = [touch locationInView:self]; //current position of touch if (([touch view] == self) && [Utility getDistance:currentPoint toPoint:self.middle] <= ROTATE_RADIUS && [Utility getDistance:currentPoint toPoint:self.middle] >= MOVE_RADIUS) { //a rotation gesture //rotate tile float newAngle = angleBetweenLines(self.middle, CGPointMake(self.middle.x, 0), self.middle, currentPoint); //touch angle float angleDif = newAngle - self.initialAngle; //work out dif between angle at beginning of touch and now. CGAffineTransform newTransform = CGAffineTransformRotate(self.initialTransform, angleDif); //create new transform self.transform = newTransform; //apply transform. } OR 2) Should I simply remember the last known position/angle, and rotate the view based on the difference in angle between that and now, e.g.,: - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { UITouch *touch = [touches anyObject]; CGPoint currentPoint = [touch locationInView:self]; //current position of touch if (([touch view] == self) && [Utility getDistance:currentPoint toPoint:self.middle] <= ROTATE_RADIUS && [Utility getDistance:currentPoint toPoint:self.middle] >= MOVE_RADIUS) { //will be rotation gesture //remember state of view at beginning of touch CGPoint top = CGPointMake(self.middle.x, 0); self.lastTouch = currentPoint; self.lastAngle = angleBetweenLines(self.middle, top, self.middle, currentPoint); } } - (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event{ UITouch *touch = [touches anyObject]; CGPoint currentPoint = [touch locationInView:self]; //current position of touch if (([touch view] == self) && [Utility getDistance:currentPoint toPoint:middle] <= ROTATE_RADIUS && [Utility getDistance:currentPoint toPoint:middle] >= MOVE_RADIUS) { //a rotation gesture //rotate tile float newAngle = angleBetweenLines(self.middle, CGPointMake(self.middle.x, 0), self.middle, currentPoint); //touch angle float angleDif = newAngle - self.lastAngle; //work out dif between angle at beginning of touch and now. CGAffineTransform newTransform = CGAffineTransformRotate(self.transform, angleDif); //create new transform self.transform = newTransform; //apply transform. self.lastTouch = currentPoint; self.lastAngle = newAngle; } The second option makes more sense to me, but it is not giving very pleasing results (jaggy updates and non-smooth rotations). Which way is best (if any), in terms of performance? Cheers!

  • How can I load style resources from a dynamically loaded Silverlight application (XAP)?

    - by Tom
    I've followed Tim Heuer's video for dynamically loading other XAP's (into a 'master' Silverlight application), as well as some other links to tweak the loading of resources and am stuck on the particular issue of loading style resources from within the dynamically loaded XAP (i.e. the contents of Assets\Styles.xaml). When I run the master/hosting applcation, it successfully streams the dynamic XAP and I can read the deployment info etc. and load the assembly parts. However, when I actuall try to create an instance of a form from the Dynamic XAP, it fails with Cannot find a Resource with the Name/Key LayoutRootGridStyle which is in it's Assets\Styles.xaml file (it works if I run it directly so I know it's OK). For some reason these don't show up as application resources - not sure if I've totally got the wrong end of the stick, or am just missing something? Code snippet below (apologies it's a bit messy - just trying to get it working first) ... '' # Here's the code that reads the dynamic XAP from the web server ...

  • Finding edge and corner values of an image in matlab

    - by James
    Hi, this problem links to two other questions i've asked on here. I am tracing the outline of an image and plotting this to a dxf file. I would like to use the bwboundaries function to find the coordinates of the edges of the image, find the corner coordinates using the cornermetric function and then remove any edge coordinates that are not a corner. The important thing I need to be able to do is keep the order of the corner elements obtained from bwboundaries, so that the section traces properly. The dxf function I have that draws from the coordinates draws lines between coordinates that are next to each other, so the line has to be drawn "around" the section rather than straight between the corner points. The reason I am doing this is because there are less coordinates obtained this way, so it is easier to amend the dxf file (as there are less points to manipulate). The code I have so far is: %# Shape to be traced bw = zeros(200); bw(20:40,20:180) = 1; bw(20:180,90:110) = 1; bw(140:180,20:185) = 1; %# Boundary Finding Section [Boundary] = bwboundaries(bw); %Traces the boundary of each section figure, imshow(bw); hold on; colors=['b' 'g' 'r' 'c' 'm' 'y']; for k=1:length(Boundary) perim = Boundary{k}; %Obtains perimeter coordinates (as a 2D matrix) from the cell array cidx = mod(k,length(colors))+1;% Obtains colours for the plot plot(perim(:,2), perim(:,1),... colors(cidx),'LineWidth',2); end Coordmat = cell2mat(Boundary) %Converts the traced regions to a matrix X = Coordmat(:,1) Y = Coordmat(:,2) % This gives the edge coordinates in matrix form %% Corner Finding Section (from Jonas' answer to a previous question %# get corners cornerProbability = cornermetric(bw); cornerIdx = find(cornerProbability==max(cornerProbability(:))); %# Label the image. bwlabel puts 1 for the first feature, 2 for the second, etc. %# Since concave corners are placed just outside the feature, grow the features %# a little before labeling bw2 = imdilate(bw,ones(3)); labeledImage = bwlabel(bw2); %# read the feature number associated with the corner cornerLabels = labeledImage(cornerIdx); %# find all corners that are associated with feature 1 corners_1 = cornerIdx(cornerLabels==1) [Xcorners, Ycorners] = ind2sub(200,corners_1) % Convert subscripts The code I have is, to give a matrix Xfin for the final x coordinates (which are on the edge AND at a corner. Xfin = zeros(length(X),1) for i = Xcorners XFin(i) = Xcorners if i~= Xcorners XFin(i) = [] end end However, this does not work correctly, because the values in the solution are sorted into order, and only one of each value remains. As I said, I would like the corner elements to be in the same order as obtained from bwboundaries, to allow the image to trace properly. Thanks

  • Lots of questions about file I/O (reading/writing message strings)

    - by Nazgulled
    Hi, For this university project I'm doing (for which I've made a couple of posts in the past), which is some sort of social network, it's required the ability for the users to exchange messages. At first, I designed my data structures to hold ALL messages in a linked list, limiting the message size to 256 chars. However, I think my instructors will prefer if I save the messages on disk and read them only when I need them. Of course, they won't say what they prefer, I need to make a choice and justify the best I can why I went that route. One thing to keep in mind is that I only need to save the latest 20 messages from each user, no more. Right now I have an Hash Table that will act as inbox, this will be inside the user profile. This Hash Table will be indexed by name (the user that sent the message). The value for each element will be a data structure holding an array of size_t with 20 elements (20 messages like I said above). The idea is to keep track of the disk file offsets and bytes written. Then, when I need to read a message, I just need to use fseek() and read the necessary bytes. I think this could work nicely... I could use just one single file to hold all messages from all users in the network. I'm saying one single file because a colleague asked an instructor about saving the messages from each user independently which he replied that it might not be the best approach cause the file system has it's limits. That's why I'm thinking of going the single file route. However, this presents a problem... Since I only need to save the latest 20 messages, I need to discard the older ones when I reach this limit. I have no idea how to do this... All I know is about fread() and fwrite() to read/write bytes from/to files. How can I go to a file offset and say "hey, delete the following X bytes"? Even if I could do that, there's another problem... All offsets below that one will be completely different and I would have to process all users mailboxes to fix the problem. Which would be a pain... So, any suggestions to solve my problems? What do you suggest?

  • Architecture for a business objects / database access layer

    - by gregmac
    For various reasons, we are writing a new business objects/data storage library. One of the requirements of this layer is to separate the logic of the business rules, and the actual data storage layer. It is possible to have multiple data storage layers that implement access to the same object - for example, a main "database" data storage source that implements most objects, and another "ldap" source that implements a User object. In this scenario, User can optionally come from an LDAP source, perhaps with slightly different functionality (eg, not possible to save/update the User object), but otherwise it is used by the application the same way. Another data storage type might be a web service, or an external database. There are two main ways we are looking at implementing this, and me and a co-worker disagree on a fundamental level which is correct. I'd like some advice on which one is the best to use. I'll try to keep my descriptions of each as neutral as possible, as I'm looking for some objective view points here. Business objects are base classes, and data storage objects inherit business objects. Client code deals with data storage objects. In this case, common business rules are inherited by each data storage object, and it is the data storage objects that are directly used by the client code. This has the implication that client code determines which data storage method to use for a given object, because it has to explicitly declare an instance to that type of object. Client code needs to explicitly know connection information for each data storage type it is using. If a data storage layer implements different functionality for a given object, client code explicitly knows about it at compile time because the object looks different. If the data storage method is changed, client code has to be updated. Business objects encapsulate data storage objects. In this case, business objects are directly used by client application. Client application passes along base connection information to business layer. Decision about which data storage method a given object uses is made by business object code. Connection information would be a chunk of data taken from a config file (client app does not really know/care about details of it), which may be a single connection string for a database, or several pieces connection strings for various data storage types. Additional data storage connection types could also be read from another spot - eg, a configuration table in a database that specifies URLs to various web services. The benefit here is that if a new data storage method is added to an existing object, a configuration setting can be set at runtime to determine which method to use, and it is completely transparent to the client applications. Client apps do not need to be modified if data storage method for a given object changes. Business objects are base classes, data source objects inherit from business objects. Client code deals primarily with base classes. This is similar to the first method, but client code declares variables of the base business object types, and Load()/Create()/etc static methods on the business objects return the appropriate data source-typed objects. The architecture of this solution is similar to the first method, but the main difference is the decision about which data storage object to use for a given business object is made by the business layer, not the client code. I know there are already existing ORM libraries that provide some of this functionality, but please discount those for now (there is the possibility that a data storage layer is implemented with one of these ORM libraries) - also note I'm deliberately not telling you what language is being used here, other than that it is strongly typed. I'm looking for some general advice here on which method is better to use (or feel free to suggest something else), and why.

  • Understanding Node.js and concept of non-blocking I/O

    - by Saif Bechan
    Recently I became interested in using Node.js to tackle some of the parts of my web-application. I love the part that its full JavaScript and its very light weight so no use anymore to call an JavaScript-PHP call but a lighter JavaScript-JavaScript call. I however do not understand all the concepts explained. Basic concepts Now in the presentation for Node.js Ryan Dahl talks about non-blocking IO and why this is the way we need to create our programs. I can understand the theoretical concept. You just don't wait for a response, you go ahead and do other things. You make a callback for the response, and when the response arrives millions of clock-cycles later, you can fire that. If you have not already I recommend to watch this presentation. It is very easy to follow and pretty detailed. There are some nice concepts explained on how to write your code in a good manner. There are also some examples given and I am going to work with the basic example given. Examples The way we do thing now: puts("Enter your name: "); var name = gets(); puts("Name: " + name); Now the problem with this is that the code is halted at line 1. It blocks your code. The way we need to do things according to node puts("Enter your name: "); gets(function (name) { puts("Name: " + name); }); Now with this your program does not halt, because the input is a function within the output. So the programs continues to work without halting. Questions Now the basic question I have is how does this work in real-life situations. I am talking here for the use in web-applications. The application I am writing does I/O, bit is still does it in am blocking matter. I think that most of the time, if not all, you need to block, because you have to wait on what the response is you have to work with. When you need to get some information from the database, most of the time this data needs to be verified before you can further with the code. Example 1 If you take a login for example. You have to wait for the database to response to return, because you can not do anything else. I can't see a way around this without blocking. Example 2 Going back to the basic example. The use just request something from a database which does not need any verification. You still have to block because you don't have anything to do more. I can not come up with a single example where you want to do other things while you wait for the response to return. Possible answers I have read that this frees up recourses. When you program like this it takes less CPU or memory usage. So this non-blocking IO is ONLY meant to free up recourses and does not have any other practical use. Not that this is not a huge plus, freeing up recourses is always good. Yet I fail to see this as a good solution. because in both of the above examples, the program has to wait for the response of the user. Whether this is inside a function, or just inline, in my opinion there is a program that wait for input. Resources I looked at I have looked at some recourses before I posted this question. They talk a lot about the theoretical concept, which is quite clear. Yet i fail to see some real-life examples where this is makes a huge difference.

  • Macro doesn't work in the function.

    - by avp
    I have problems with following code: http://lisper.ru/apps/format/96 The problem is in "normalize" function, which does not work. It fails on the fifth line: (zero-p a indexes i) (defun normalize (a &optional indexes i) "Returns normalized A." (pragma (format t "Data=~A ~A ~A" a indexes i) (if (zero-p a indexes i) a ;; cannot normalize empty vector (let* ((mmm (format t "Zero?=~a" (zero-p a indexes i))) (L (sqrt (+ (do-op-on * a :x a :x indexes i indexes i) (do-op-on * a :y a :y indexes i indexes i) (do-op-on * a :z a :z indexes i indexes i)))) (mmm (format t "L=~a" L)) (L (/ 1D0 L)) (mmm (format t "L=~a" L))) ; L=1/length(A) (make-V3 (* (ref-of a :x indexes i) l) (* (ref-of a :y indexes i) l) (* (ref-of a :z indexes i) l)))))) in function "normalize" I call the macro "zero-p", which in turn calls macro "ref-of", which is the last in the chain. (defmacro zero-p (v &optional indexes index) "Checks if the vector is 'almost' zero length." `(and (< (ref-of ,v :x ,indexes ,index) *min+*) (< (ref-of ,v :y ,indexes ,index) *min+*) (< (ref-of ,v :z ,indexes ,index) *min+*) (> (ref-of ,v :x ,indexes ,index) *min-*) (> (ref-of ,v :y ,indexes ,index) *min-*) (> (ref-of ,v :z ,indexes ,index) *min-*))) Here is ref-of: (defmacro ref-of (values coordinate &optional indexes index) "Please see DATA STRUCTURE for details." (if indexes (cond ((eq coordinate :x) `(aref ,values (aref ,indexes ,index))) ((eq coordinate :y) `(aref ,values (+ 1 (aref ,indexes ,index)))) ((eq coordinate :z) `(aref ,values (+ 2 (aref ,indexes ,index)))) (T (error "The symbol ~S is not :X, :Y or :Z." coordinate))) (cond ((eq coordinate :x) `(aref ,values 0)) ((eq coordinate :y) `(aref ,values 1)) ((eq coordinate :z) `(aref ,values 2)) (T (error "The symbol ~S is not :X, :Y or :Z." coordinate))))) Also, in "normalize" I call the macro "do-op-on", which calls "ref-of" as well. (defmacro do-op-on (op name1 coord1 name2 coord2 &optional is1 i1 is2 i2) "Example: (do-op-on * A :x B :y i n) == A[i[n]].x*B.y" `(,op (ref-of ,name1 ,coord1 ,is1 ,i1) (ref-of ,name2 ,coord2 ,is2 ,i2))) As a result, instead of having this: (aref some-array 0) I have (aref NIL NIL) which is created in "ref-of". I suppose that I lose the symbol A from the call (normalize A). I just feel that the symbol does not survive the macroexpanson. The thing is, macroexpansoin works in REPL for each macro independently. Can anyone explain where is the mistake?

  • Can't get tokens when using OAuth with LinkedIn API

    - by Angela
    Hi, was wondering if anyone can help me to get this basic OAuth implementation to work using the LinkedIn API: The output for the indexes oauth_token and oauth_token_secret are blank. The file I refer to in OAuth.php are a set of classes to help generate the token requests and tokens. That file is here: http://www.easy-share.com/1909603316/OAuth.php <?php session_start(); require_once("OAuth.php"); $app_token = "YOUR APP TOKEN GOES HERE"; $app_key = "YOUR APP KEY GOES HERE"; $domain = "https://api.linkedin.com/uas/oauth"; $sig_method = new OAuthSignatureMethod_HMAC_SHA1(); $test_consumer = new OAuthConsumer($app_token, $app_key, NULL); $callback = "http://".$_SERVER['HTTP_HOST'].$_SERVER['PHP_SELF']."?action=getaccesstoken"; # First time through, get a request token from LinkedIn. if (!isset($_GET['action'])) { $req_req = OAuthRequest::from_consumer_and_token($test_consumer, NULL, "POST", $domain . "/requestToken"); $req_req->set_parameter("oauth_callback", $callback); # part of OAuth 1.0a - callback now in requestToken $req_req->sign_request($sig_method, $test_consumer, NULL); $ch = curl_init(); // make sure we submit this as a post curl_setopt($ch, CURLOPT_POSTFIELDS, ''); //New Line curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0); curl_setopt($ch, CURLOPT_HTTPHEADER,array ( $req_req->to_header() )); curl_setopt($ch, CURLOPT_URL, $domain . "/requestToken"); curl_setopt($ch, CURLOPT_POST, 1); $output = curl_exec($ch); curl_close($ch); print_r($req_req); //<---- add this line print("$output\n"); //<---- add this line parse_str($output, $oauth); # pop these in the session for now - there's probably a more secure way of doing this! We'll need them when the callback is called. $_SESSION['oauth_token'] = $oauth['oauth_token']; $_SESSION['oauth_token_secret'] = $oauth['oauth_token_secret']; echo("token: " . $oauth['oauth_token']); echo("secret: " . $oauth['oauth_token_secret']); exit;

  • Why does the proxy generated code create the wrong class namespace when a MessageContract is in my W

    - by DaleyKD
    I have created two WCF Services (Shipping & PDFGenerator). They both, along with my ClientApp, share an assembly named Kyle.Common.Contracts. Within this assembly, I have three classes: namespace Kyle.Common.Contracts { [MessageContract] public class PDFResponse { [MessageHeader] public string fileName { get; set; } [MessageBodyMember] public System.IO.Stream fileStream { get; set; } } [MessageContract] public class PDFRequest { [MessageHeader] public Enums.PDFDocumentNameEnum docType { get; set; } [MessageHeader] public int? pk { get; set; } [MessageHeader] public string[] emailAddress { get; set; } [MessageBodyMember] public Kyle.Common.Contracts.TrackItResult[] trackItResults { get; set; } } [DataContract(Name = "TrackResult", Namespace = "http://kyle")] public class TrackResult { [DataMember] public int SeqNum { get; set; } [DataMember] public int ShipmentID { get; set; } [DataMember] public string StoreNum { get; set; } } } My PDFGenerator ServiceContract looks like: namespace Kyle.WCF.PDFDocs { [ServiceContract(Namespace="http://kyle")] public interface IPDFDocsService { [OperationContract] PDFResponse GeneratePDF(PDFRequest request); [OperationContract] void GeneratePDFAsync(Kyle.Common.Contracts.Enums.PDFDocumentNameEnum docType, int? pk, string[] emailAddress); [OperationContract] Kyle.Common.Contracts.TrackResult[] Test(); } } If I comment out the GeneratePDF stub, the proxy generated by VS2010 realizes that Test returns an array of Kyle.Common.Contracts.TrackResult. However, if I leave GeneratePDF there, the proxy refuses to use Kyle.Common.Contracts.TrackResult, and instead creates a new class, ClientApp.PDFDocServices.TrackResult, and uses that as the return type of Test. Is there a way to force the proxy generator to use Kyle.Common.Contracts.TrackResult whenever I use a MessageContract? Perhaps there's a better method for using a Stream and File Name as return types? I just don't want to have to create a Copy method to copy from ClientApp.PDFDocServices.TrackResult to Kyle.Common.Contracts.TrackResult, since they should be the exact same class. Thanks in advance, Kyle
