  • How to choose between protobuf-csharp-port and protobuf-net

    - by PierrOz
    Hi Folks, I've recently had to look for a C# porting of the Protocole Buffer library originally developped by Google. And guess what, I found two projects owned both by two very well known persons here: protobuf-csharp-port, written by Jon Skeet and protobuf-net, written by Mark Gravell. My question is simple: which one do I have to choose ? I quite like Mark's solution as it seems to me closer to C# philisophy (for instance, you can just add attributes to the properties of existing class) and it looks like it can support .NET built-in types such as System.Guid. I am sure both of them are really great projects but what's your oppinion?

  • Set Proxy Credential in Web Browser Control

    - by rockacola
    I am working on a legacy code where an application uses AxSHDocVw.AxWebBrowser (NOT System.Windows.Forms.Control) to open up web pages and am extending it to take proxy into considerations. I have following example on http://www.pinvoke.net/default.aspx/wininet/internetsetoption.html to use InternetSetOption() to go through specified proxy and tested that it works. Now the hurdle is I tried everything but failed to pass username and password with following code: //-- Set Proxy Username bool resultF = InternetSetOption(IntPtr.Zero, INTERNET_OPTION_PROXY_USERNAME, username, username.Length+1); var errorF = Marshal.GetLastWin32Error(); //-- Set Proxy Password bool resultG = InternetSetOption(IntPtr.Zero, INTERNET_OPTION_PROXY_PASSWORD, password, password.Length+1); var errorG = Marshal.GetLastWin32Error(); Both resultF and resultG return true and has no errors but it still working. Any hint on what may be happening here? and what method do I have to debug this? Thanks in advance.

  • autocomplete dropdown in Infragistics ultrawebgrid cell

    - by Rama
    Hi, I want to an autocomplete dropdown control in the ultrawebgrid cell in edit mode, so user can type the data and value is filled in automatically if exists, invalid data should not be permitted. is this possible? I don't want to use webcombo, it is too heavy and I don't need a multi-column dropdown. I want a simple dropdownlist, but the ability for the user to type just like Google suggest, but all the values cached on the client, no roundtrip to server on each key stroke. the control should be like the following one http://www.asp.net/AJAX/AjaxControlToolkit/Samples/ComboBox/ComboBox.aspx thanks, RK

  • Problem with accessing variables/functions from subclass Objective C

    - by Mitul Ruparelia
    Hi, I am having a problem with accessing public variable 'activity', which is a UIActivityIndicatorView type, see class declaration below in QuickStartViewController.h: @interface QuickStartViewController : UIViewController <ABPeoplePickerNavigationControllerDelegate> { @public IBOutlet UIActivityIndicatorView *activity; } @property (nonatomic, retain) UIActivityIndicatorView *activity; @end The function is called from another class: #import "QuickStartViewController.h" @interface NumberValidator : QuickStartViewController.... See below: - (void)connectionDidFinishLoading:(NSURLConnection *)connection { [activity startAnimating]; NSLog(@"This function is called, but [activity startAnimating] still doesn't work..."); } Note: [activity startAnimating] works fine when called within the QuickStartViewController class Do you have any suggestions as to why [activity startAnimating] is not working?

  • How do I use AutofacWebTypesModule to Resolve HttpServerUtilityBase

    - by Scott Weinstein
    I have the following registrations builder.RegisterModule(new AutofacWebTypesModule()); builder.Register<MyType>(ctx => { var server = ctx.Resolve<HttpServerUtilityBase>(); ... }); When I try to resolve MyType via a constructor on an Controller, I get the following exception. What am I doing wrong? Autofac.Core.DependencyResolutionException was unhandled by user code Message=No scope matching the expression 'value(Autofac.Builder.RegistrationBuilder`3+<c__DisplayClass0[System.Web.HttpServerUtilityBase,Autofac.Builder.SimpleActivatorData,Autofac.Builder.SingleRegistrationStyle]).lifetimeScopeTag.Equals(scope.Tag)' is visible from the scope in which the instance was requested.

  • iPhone Serialization problem

    - by Jenicek
    Hi, I need to save my own created class to file, I found on the internet, that good approach is to use NSKeyedArchiver and NSKeyedUnarchiver My class definition looks like this: @interface Game : NSObject <NSCoding> { NSMutableString *strCompleteWord; NSMutableString *strWordToGuess; NSMutableArray *arGuessedLetters; //This array stores characters NSMutableArray *arGuessedLettersPos; //This array stores CGRects NSInteger iScore; NSInteger iLives; NSInteger iRocksFallen; BOOL bGameCompleted; BOOL bGameOver; } I've implemented methods initWithCoder: and encodeWithCoder: this way: - (id)initWithCoder:(NSCoder *)coder { if([coder allowsKeyedCoding]) { strCompleteWord = [[coder decodeObjectForKey:@"CompletedWord"] copy]; strWordToGuess = [[coder decodeObjectForKey:@"WordToGuess"] copy]; arGuessedLetters = [[coder decodeObjectForKey:@"GuessedLetters"] retain]; // arGuessedLettersPos = [[coder decodeObjectForKey:@"GuessedLettersPos"] retain]; iScore = [coder decodeIntegerForKey:@"Score"]; iLives = [coder decodeIntegerForKey:@"Lives"]; iRocksFallen = [coder decodeIntegerForKey:@"RocksFallen"]; bGameCompleted = [coder decodeBoolForKey:@"GameCompleted"]; bGameOver = [coder decodeBoolForKey:@"GameOver"]; } else { strCompleteWord = [[coder decodeObject] retain]; strWordToGuess = [[coder decodeObject] retain]; arGuessedLetters = [[coder decodeObject] retain]; // arGuessedLettersPos = [[coder decodeObject] retain]; [coder decodeValueOfObjCType:@encode(NSInteger) at:&iScore]; [coder decodeValueOfObjCType:@encode(NSInteger) at:&iLives]; [coder decodeValueOfObjCType:@encode(NSInteger) at:&iRocksFallen]; [coder decodeValueOfObjCType:@encode(BOOL) at:&bGameCompleted]; [coder decodeValueOfObjCType:@encode(BOOL) at:&bGameOver]; } return self; } - (void)encodeWithCoder:(NSCoder *)coder { if([coder allowsKeyedCoding]) { [coder encodeObject:strCompleteWord forKey:@"CompleteWord"]; [coder encodeObject:strWordToGuess forKey:@"WordToGuess"]; [coder encodeObject:arGuessedLetters forKey:@"GuessedLetters"]; //[coder encodeObject:arGuessedLettersPos forKey:@"GuessedLettersPos"]; [coder encodeInteger:iScore forKey:@"Score"]; [coder encodeInteger:iLives forKey:@"Lives"]; [coder encodeInteger:iRocksFallen forKey:@"RocksFallen"]; [coder encodeBool:bGameCompleted forKey:@"GameCompleted"]; [coder encodeBool:bGameOver forKey:@"GameOver"]; } else { [coder encodeObject:strCompleteWord]; [coder encodeObject:strWordToGuess]; [coder encodeObject:arGuessedLetters]; //[coder encodeObject:arGuessedLettersPos]; [coder encodeValueOfObjCType:@encode(NSInteger) at:&iScore]; [coder encodeValueOfObjCType:@encode(NSInteger) at:&iLives]; [coder encodeValueOfObjCType:@encode(NSInteger) at:&iRocksFallen]; [coder encodeValueOfObjCType:@encode(BOOL) at:&bGameCompleted]; [coder encodeValueOfObjCType:@encode(BOOL) at:&bGameOver]; } } And I use these methods to archive and unarchive data: [NSKeyedArchiver archiveRootObject:currentGame toFile:strPath]; Game *currentGame = [NSKeyedUnarchiver unarchiveObjectWithFile:strPath]; I have two problems. 1) As you can see, lines with arGuessedLettersPos is commented, it's because every time I try to encode this array, error comes up(this archiver cannot encode structs), and this array is used for storing CGRect structs. I've seen solution on the internet. The thing is, that every CGRect in the array is converted to an NSString (using NSStringFromCGRect()) and then saved. Is it a good approach? 2)This is bigger problem for me. Even if I comment this line and then run the code successfully, then save(archive) the data and then try to load (unarchive) them, no data is loaded. There aren't any error but currentGame object does not have data that should be loaded. Could you please give me some advice? This is first time I'm using archivers and unarchivers. Thanks a lot for every reply.

  • sync Framework for Compact Framework

    - by CF_Maintainer
    Has anyone got sync framework to work on a mobile device as a sync mechanism in place of RDA or Merge replication? If yes, could you point me to any resources available. If one was to start a green field compact framework based application, what would one use as the sync mechanism (sync framework/RDA/Merge replication/any other...)? Thanks

  • assembly registers beginner

    - by Dnaiel
    So I've been getting into a bit of assembly lately and I'm a beginner so i was wondering if someone could clarify something. I take it every process has it's own set of registers, and each thread can modify these registers right?. How then do multiple threads use the same registers without causing clashes? Or does each thread have its own set of registers?

  • Three20 TTLauncherView Tutorial?

    - by Graeme
    Hi, I'm attempting to use TTLauncherView from the Facebook Three20 project in my app, but I'm not having much luck (I'm a bit of a newbie at this). Does anyone have any good tutorials at using it that I could read? FYI basically I need to pull images that a user chooses from the iPhone camera album, and display them as icons that when pressed lead to another view. Thanks.

  • Implementing a listview inside a sliding drawer with a listview already present

    - by Parker
    I have an app whose main class extends ListActivity: public class GUIPrototype extends ListActivity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); final Cursor c = managedQuery(People.CONTENT_URI, null, null, null, null); String[] from = new String[] {People.NAME}; int[] to = new int[] { R.id.row_entry }; SimpleCursorAdapter adapter = new SimpleCursorAdapter(this,R.layout.drawer,c,from,to); setListAdapter(adapter); getListView().setTextFilterEnabled(true); } } I have a sliding drawer included in my XML, and I'm trying to get a separate listview to appear in the sliding drawer. I'm trying to populate the second listview using an inflater: View inflatedView = View.inflate(this, R.layout.main, null); ListView namesLV = (ListView) inflatedView.findViewById(R.id.content); String[] names2 = new String[] { "CS 345", "New Tag", "Untagged" }; ArrayAdapter<String> bb = new ArrayAdapter<String>(this, R.layout.main, R.id.row_entry, names2); namesLV.setAdapter(bb); This compiles, and runs, but the slidingdrawer is completely blank. My XML follows: <SlidingDrawer android:id="@+id/drawer" android:handle="@+id/handle" android:content="@+id/content" android:layout_width="fill_parent" android:layout_height="wrap_content" android:orientation="vertical" android:layout_gravity="bottom"> <ImageView android:id="@id/handle" android:layout_width="48px" android:layout_height="48px" android:background="@drawable/icon"/> <ListView android:layout_width="fill_parent" android:layout_height="wrap_content" android:id="@id/content"/> </SlidingDrawer> I feel like I'm missing a vital step. I haven't found any resources on my problem by Googling, so any help would be greatly appreciated.

  • Facebook FQL - How do I fetch the posts I made to a friend's wall

    - by simianarmy
    I have a facebook desktop app with some test users all having granted the stream_read & offline access permissions. I can easily retrieve posts to each users' stream & profile. What I cannot do easily is retrieve posts that a user has made to one of their friend's walls. In fact, this used to work with a rather complex multiquery, but has stopped working now, or is working only intermittently... Does anyone care to share their method if one exists or discuss what restrictions there might be to this type of complex querying?

  • 407 Proxy Authentication Required

    - by Hemant Kothiyal
    I am working on a website, in which I am retrieving XML data from an external URL, using the following code WebRequest req = WebRequest.Create("External server url"); req.Proxy = new System.Net.WebProxy("proxyUrl:8080", true); req.Proxy.Credentials = CredentialCache.DefaultCredentials; WebResponse resp = req.GetResponse(); StreamReader textReader = new StreamReader(resp.GetResponseStream()); XmlTextReader xmlReader = new XmlTextReader(textReader); XmlDocument xmlDoc = new XmlDocument(); xmlDoc.Load(xmlReader); This code is working fine on my development PC (Windows XP with .Net 3.5) But when I deploy this code to IIS (Both at Windows XP and at Windows Server 2003) it's giving me following error "The remote server returned an error: (407) Proxy Authentication Required." Sometimes it gives me "The remote server returned an error: (502) Bad Gateway." Following code is from my web.config <system.net> <defaultProxy> <proxy usesystemdefault="False" proxyaddress ="http://172.16.12.12:8080" bypassonlocal ="True" /> </defaultProxy> </system.net> Please help me ? [Edit] Even when i run the website for devlopment PC but through IIS it gives me error "The remote server returned an error: (407) Proxy Authentication Required."

  • What is the difference between System.Speech.Recognition and Microsoft.Speech.Recognition?

    - by Michael
    There are two similar namespaces and assemblies for speech recognition in .NET. I’m trying to understand the differences and when it is appropriate to use one or the other. There is System.Speech.Recognition from the assembly System.Speech (in System.Speech.dll). System.Speech.dll is a core DLL in the .NET Framework class library 3.0 and later There is also Microsoft.Speech.Recognition from the assembly Microsoft.Speech (in microsoft.speech.dll). Microsoft.Speech.dll is part of the UCMA 2.0 SDK I find the docs confusing and I have the following questions: System.Speech.Recognition says it is for "The Windows Desktop Speech Technology", does this mean it cannot be used on a server OS or cannot be used for high scale applications? The UCMA 2.0 Speech SDK ( http://msdn.microsoft.com/en-us/library/dd266409%28v=office.13%29.aspx ) says that it requires Microsoft Office Communications Server 2007 R2 as a prerequisite. However, I’ve been told at conferences and meetings that if I do not require OCS features like presence and workflow I can use the UCMA 2.0 Speech API without OCS. Is this true? If I’m building a simple recognition app for a server application (say I wanted to automatically transcribe voice mails) and I don’t need features of OCS, what are the differences between the two APIs?

  • C# PredicateBuilder Entities: The parameter 'f' was not bound in the specified LINQ to Entities quer

    - by Neothor
    I needed to build a dynamic filter and I wanted to keep using entities. Because of this reason I wanted to use the PredicateBuilder from albahari. I created the following code: var invoerDatums = PredicateBuilder.True<OnderzoeksVragen>(); var inner = PredicateBuilder.False<OnderzoeksVragen>(); foreach (var filter in set.RapportInvoerFilter.ToList()) { if(filter.IsDate) { var date = DateTime.Parse(filter.Waarde); invoerDatums = invoerDatums.Or(o => o.Van >= date && o.Tot <= date); } else { string temp = filter.Waarde; inner = inner.Or(o => o.OnderzoekType == temp); } } invoerDatums = invoerDatums.And(inner); var onderzoeksVragen = entities.OnderzoeksVragen .AsExpandable() .Where(invoerDatums) .ToList(); When I ran the code there was only 1 filter which wasn't a date filter. So only the inner predicate was filled. When the predicate was executed I got the following error. The parameter 'f' was not bound in the specified LINQ to Entities query expression. While searching for an answer I found the following page. But this is already implemented in the LINQKit. Does anyone else experienced this error and know how to solve it?

  • Creating .NET 3.0 sub-applications within .NET 1.1 applications in IIS/ASP.Net

    - by Karen
    I am basically trying to do the same thing as this question, create a new application within a folder so it could be accessed as follows. * http://www.domain.com/ < Main App * http://www.domain.com/newapp < New App The problem is that newapp is reading the web.config from the Main App, which is causing errors because it doesn't have all the same dlls etc. For New App, in IIS, the starting point is set at /newapp, so I am not sure why it is reading the web.config from / at all. It is set as it's own application. I am testing this in IIS6 on XP Pro, so not sure if that makes a difference. The Main App is dotnet 1.1, and New App is 3.0. Edit: Adding 'inheritInChildApplications to <location doesn't work in 1.1, you get an error: Parser Error Message: Unrecognized attribute 'inheritInChildApplications'

  • Multiple Silverlight Unit Test Projects in Solution

    - by IUnknown
    I am building out a number of Silverlight 4.0 libraries that are part of the same solution. I like to break them into separate projects and have a Unit Test project for each: SolutionX -LibraryProject1 ---Class1.cs ---Class2.cs -LibraryProject1.Test ---Tests1.cs ---Tests2.cs -LibraryProject2 ---Class1.cs ---Class2.cs ---CLass3.cs -LibraryProject2.Test ---Tests1.cs ---Tests2.cs ---Tests3.cs -LibraryProject3 ---Class1.cs -LibraryProject3.Test ---Tests1.cs This works great when using VS regular test projects and infrastructure because I can create and execute list of test that are aggregated from each Test project. But with the Silverlight Unit Test Framework since the Silverlight Unit Test Project must be the "start up project" I cannot figure how to run a collection of tests from each test project in one go. I have to run each separately then switch the starting project each time. I would prefer to avoid create complex build scripts or build definitions - is there a way to run all the tests at once? -Thanks
