  • XamlWriter fails to serialize objects in WinForms app

    - by Eddie
    Apparently XamlWriter doesn't works correctly in a WinForms application. XamlWriter uses MarkupWriter.GetMarkupObjectFor(object obj). I suppose that there's a problem to determine the full list of properties to serialize. var ar = new AssemblyReference(AppDomain.CurrentDomain.GetAssemblies().First()); var str = XamlWriter.Save(ar); Running an ASP.NET or WPF application I got this result: <AssemblyReference AssemblyName="mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" HintPath="file:///c:/WINDOWS/Microsoft.NET/Framework/v2.0.50727/mscorlib.dll" SpecificVersion="False" xmlns="clr-namespace:Ivolutia.TypeModel;assembly=ivoTypeModel" /> But running the same code in a WinForms application I got this: <AssemblyReference xmlns="clr-namespace:Ivolutia.TypeModel;assembly=ivoTypeModel" /> this is the class definition: public class AssemblyReference : DependencyObject { public string AssemblyName { get; set; } public string HintPath { get; set; } public bool SpecificVersion { get; set; } public AssemblyReference() { } public AssemblyReference(Assembly assembly) { AssemblyName = assembly.FullName; HintPath = assembly.CodeBase; } public override string ToString() { return AssemblyName; } }

  • Google Chrome, IE problem with adjusting style before AJAX

    - by orokusaki
    When I'm using AJAX, I typically do something before each request to let the user know that they'll be waiting for a second. This is usually done by just adding an animated loading gif. When I do this, Firefox does what you'd expect and adds the gif before moving control to the next line (where the AJAX is called). In Chrome, it locks the browser and doesn't make any DOM changes at all (let alone load an image), including even changing the color of something, until the AJAX is done. This isn't just AJAX though. It's anything that holds control, and it never makes DOM changes until the control is given back to the window. Example (using jQuery): function submit_order() { $('#my_element').css('color', '#FF0000'); // Make text red before calling AJAX $.getJSON('/api/', my_callback) // Note, in IE and Chrome #my_element isn't turned red until the AJAX finishes and my_callback is run } Why does this happen, and how can I solve it? I can't use ASYNC because of the nature of the data (it would be a big mess). I experimented with using window.setTimeout(myajaxfunc, 150) after setting the style, to see if it would set the style, then do the timeout, but it appears it isn't an issue with just AJAX, but rather the control of the script in general (I think, hence the title making mention to AJAX because this is the only time I ever run into this problem). This doesn't have anything to do with it being in a function BTW.

  • Facebook app submit action type

    - by Axel
    I've been reading about this on StackOverflow and facebook doc, yet I dont seem to be able to submit my action type. I have the following code from the FB doc <script type="text/javascript"> console.log("Function begins"); function postForm() { console.log(FB); FB.api( '/me/concoursvelirium:form', 'post', { recipe: 'http://concours.gestev.com/fbvel2012/form.php' }, function(response) { console.log("Stay"); if (!response || response.error) { console.log("error: " + response); } else { console.log('Cook was successful! Action ID: ' + response.id); } }); } </script> I have added my values from FB autogenerated values: <head prefix="og: http://ogp.me/ns# fb: http://ogp.me/ns/fb# concoursvelirium: http://ogp.me/ns/fb/concoursvelirium#"> <meta property="fb:app_id" content="194081877384051" /> <meta property="og:type" content="concoursvelirium:form" /> <meta property="og:url" content="Put your own URL to the object here" /> <meta property="og:title" content="Sample Form" /> <meta property="og:image" content="https://s-static.ak.fbcdn.net/images/devsite/attachment_blank.png" /> And yet I see no output in the console past the console.log(FB); I have no idea what I'm doing wrong. I'm also getting the Unsafe JavaScript attempt to access frame with URL error, but I have read here that I should just ignore it. Ty, Axel

  • Keeping files or database records? Java and Python

    - by danpalmer
    My website will use a Neural Network to predict thing based on user data. The user can select the data to be used in training the network and then use their trained network to predict things. I am using a framework to create, train and query the networks. This uses Java. The framework has persistence for saving a network to an XML file. What is the best way to store these files? I can see several potential ideas, but I need help on choosing which is best: Save each network to a separate XML file with a name that is stored in the database. Load this each time. Save all the networks to the same XML file with each network having a different name that is stored in the database. Somehow pass what would normally be written to an XML file to the Django site for writing to the database. This would need to be returned to the Java code when a prediction needs to be made. I am able to do 1 or 2, but I think their performance will be quite limited and I am on shared hosting at the moment, so I don't know how pleased they would be with thousands of files. Also, after adding a few thousand records to one XML file, I was noticing a massive performance hit on saving to it. If I were able to implement version 3 somehow I think it would be best. No issues with separate processes accessing the database and I think performance would be better. Not to mention having no files lying around. However, the stuff in the neural network framework I am using (Encog) for saving to a file needs access to a Java file object, not a string that could be saved to a database. Unless there is some Java magic I can do here (I know very little Java), the only way I can see of doing this would be with a temporary files but I don't know if this is the correct way to do it. I would appreciate any ideas on the best way to implement any of the above 3 ideas or any alternatives. Thanks!

  • Map tiling - What kind of projection?

    - by ikky
    Hi. I've taken a large image and divided it in to square tiles (256x256). It is made for google maps also, so the whole image is divided into z_x_y.png (Depending on zoom level). z=0 = 1x1 tile z=1 = 2x2 tilesthe z=2 = 4x4 tiles My imageMap is "flat" and is not based on a sphere like the worldmap. I'm gonna use this map on a windows mobile app (which has no google API), and all the "points of interests" is inserted into a database by longitude and latitude. And since i have to make this for the windows mobile, i just have XY coordinate system. Is it enough to just use this: MAP_WIDTH = 256*TILES_W; MAP_HEIGHT = 256*TILES_H; function convert(int lat, int lon) { int y = (int)((-1 * lat) + 90) * (MAP_HEIGHT / 180); int x = (int)(lon + 180) * (MAP_WIDTH / 360); ImagePoint p = new ImagePoint(x,y); // An object which holds the coordinates return p; } Or do i need a projection technique? Thanks in advance. Please ask, if something is unclear.

  • MapKit/Location Manager crashes app when unloading view

    - by AppGolfer
    I has a bug where my application crashed "EXC_BAD_ACCESS" when I hit the back key on my navigation bar and the view unloaded that had a MapKit (mapView) and used the Location Manager. Tried for days to fix the bug and finally came up with a fix for anyone that comes across this problem: Add this code to your dealloc (void)dealloc { mapView.delegate = nil; locationManager.delegate = nil; [mapView release]; [locationManager release];

  • iPhone contacts app styled indexed table view implementation

    - by KSH
    My Requirement: I have this straight forward requirement of listing names of people in alphabetical order in a Indexed table view with index titles being the starting letter of alphabets (additionally a search icon at the top and # to display misc values which start with a number and other special characters). What I have done so far: 1. I am using core data for storage and "last_name" is modelled as a String property in the Contacts entity 2.I am using a NSFetchedResultsController to display the sorted indexed table view. Issues accomplishing my requirement: 1. First up, I couldn't get the section index titles to be the first letter of alphabets. Dave's suggestion in the following post, helped me achieve the same: http://stackoverflow.com/questions/1112521/nsfetchedresultscontroller-with-sections-created-by-first-letter-of-a-string The only issue I encountered with Dave' suggestion is that I couldn't get the misc named grouped under "#" index. What I have tried: 1. I tried adding a custom compare method to NSString (category) to check how the comparison and section is made but that custom method doesn't get called when specified in the NSSortDescriptor selector. Here is some code: `@interface NSString (SortString) -(NSComparisonResult) customCompare: (NSString*) aStirng; @end @implementation NSString (SortString) -(NSComparisonResult) customCompare:(NSString *)aString { NSLog(@"Custom compare called to compare : %@ and %@",self,aString); return [self caseInsensitiveCompare:aString]; } @end` Code to fetch data: `NSArray *sortDescriptors = [NSArray arrayWithObject:[[[NSSortDescriptor alloc] initWithKey:@"last_name" ascending:YES selector:@selector(customCompare:)] autorelease]]; [fetchRequest setSortDescriptors:sortDescriptors]; fetchedResultsController = [[NSFetchedResultsController alloc] initWithFetchRequest:fetchRequest managedObjectContext:managedObjectContext sectionNameKeyPath:@"lastNameInitial" cacheName:@"MyCache"];` Can you let me know what I am missing and how the requirement can be accomplished ?

  • LINQ to SQL vs Entity Framework for an app with a future SQL Azure version

    - by Craig L
    I've got a vertical market Dot Net Framework 1.1 C#/WinForms/SQL Server 2000 application. Currently it uses ADO.Net and Microsoft's SQLHelper for CRUD operations. I've successfully converted it to Dot Net Framework 4 C#/WinForms/ SQL Server 2008. What I'd like to do is also offer my customers the ability to use SQL Azure as a backend storage for their data instead of local/LAN SQL Server. If I know SQL Azure is in my application's future, should I: A. Switch to LINQ to SQL B. Swith to Entity Framework C. Stick with ADO.Net and SQLHelper Thanks !

  • Wikipedia embedded in WinForms App Tutorial

    - by RHaguiuda
    Can anyone post a tutorial here on how to show a Wikipedia article in a .NET WinForms application (C# or VB)? If the article can be placed in a string it suffices, there`s no need to put it on any control. I found some information on Wikipedia's API. After reading it, I added the reference to web service but can`t find a way to make this work. And if it's possible, explain how images are downloaded from wiki (link or image itself).

  • Fail to profile remote java app using TPTP

    - by rperez
    Hi all, I am trying to profile CPU usage using TPTP. Application to profile run on Linux RH AS5. I installed and configured Agent Controller like described here I ran the java application using the command java '-agentlib:JPIBootLoader=JPIAgent:server=standalone,file=log.trcxml;CGProf' MyApp The monitoring station is All-In-one TPTP version 4.6.2. I followed the stepes described here on Eclipse - on the "Profile Configuration" I choose a new configuration for "Attach to Agent", set the host to my remote linux machine where MyApp is running, test connection succeed and when I get to the "Agents" tab, I see "Pending...", a background process "Feching children for host" is running and can't find anything which makes it impossible to profile. Any idea?

  • Python networkx DFS or BFS missing?

    - by sadawd
    Dear Everyone I am interested in finding a path (not necessarily shortest) in a short amount of time. Dijsktra and AStar in networkx is taking too long. Why is there no DFS or BFS in networkx? I plan to write my own DFS and BFS search (I am leaning more towards BFS because my graph is pretty deep). Is there anything that I can use in networkx's lib to speed me up? Thx

  • Winforms application hangs when switching to another app

    - by joseluisrod
    Hi, I believe I have a potential threading issue. I have a user control that contains the following code: private void btnVerify_Click(object sender, EventArgs e) { if (!backgroundWorkerVerify.IsBusy) { backgroundWorkerVerify.RunWorkerAsync(); } } private void backgroundWorkerVerify_DoWork(object sender, System.ComponentModel.DoWorkEventArgs e) { VerifyAppointments(); } private void backgroundWorkerVerify_RunWorkerCompleted(object sender, System.ComponentModel.RunWorkerCompletedEventArgs e) { MessageBox.Show("Information was Verified.", "Verify", MessageBoxButtons.OK, MessageBoxIcon.Information); CloseEvent(); } vanilla code. but the issue I have is that when the application is running and the users tabs to another application when they return to mine the application is hung, they get a blank screen and they have to kill it. This started when I put the threading code. Could I have some rogue threads out there? what is the best way to zero in a threading problem? The issue can't be recreated on my machine...I know I must be missing something on how to dispose of a backgroundworker properly. Any thoughts are appreciated, Thanks, Jose

  • Good resources for building web-app in Tapestry

    - by Rich
    Hi, I'm currently researching into Tapestry for my company and trying to decide if I think we can port our pre-existing proprietary web applications to something better. Currently we are running Tomcat and using JSP for our front end backed by our own framework that eventually uses JDBC to connect to an Oracle database. I've gone through the Tapestry tutorial, which was really neat and got me interested, but now I'm faced with what seems to be a common issue of documentation. There are a lot of things I'd need to be sure that I could accomplish with Tapestry before I'd be ready to commit fully to it. Does anyone have any good resources, be it a book or web article or anything else, that go into more detail beyond what the Tapestry tutorial explains? I am also considering integrating with Hibernate, and have read a little bit about Spring too. I'm still having a hard time understanding how Spring would be more useful than cumbersome in tandem with Tapestry,as they seem to have a lot of overlapping features. An example I read seemed to use Spring to interface with Hibernate, and then Tapestry to Spring, but I was under the impression Tapestry integrates to the same degree with Hibernate. The resource I'm speaking of is http://wiki.apache.org/tapestry/Tapstry5First_project_with_Tapestry5,_Spring_and_Hibernate . I was interested because I hadn't found information anywhere else on how to maintain user levels and sessions through a Tapestry application before, but wasn't exactly impressed by the need to use Spring in the example.

  • Porting iPhone app to iPad fails to sign?

    - by mobibob
    I am able to create a new application profile targeted for my iPad, however, when I convert from iPhone to "Universal" device, I am getting an error in signing. [BEROR]Code Sign error: a valid provisioning profile matching the application's Identifier 'rfc1034identifier' could not be found Also note: I am able to run it in the simulator (which does not require signing). It is a very old application ~OS version 2.x or 3.1 that had SDK problems which required more manual process to get the signing code into the build settings, so I would not be surprised if there is some residual foo in the build settings.
