  • .NET DataGridView rows' default alignment all set to left

    - by Xster
    DataGridView gets bound to DataTable. I then try to set some columns' DefaultCellStyle.Alignment to right. It doesn't work. After a bunch of tinkering, it turns out that every single row's DefaultCellStyle.Alignment is set to left and overrides it. DataGridView.DefaultCellStyle or RowsDefaultCellStyle doesn't do anything. Makes sense since a particular row's DefaultCellStyle is more specific but what gives. Why are they all set to something and not NotSet? How do I get rid of it instead of iterating through all rows?

  • Pros/cons of reading connection string from physical file vs Application object (ASP.NET)?

    - by HaterTot
    my ASP.NET application reads an xml file to determine which environment it's currently in (e.g. local, development, production). It checks this file every single time it opens a connection to the database, in order to know which connection string to grab from the Application Settings. I'm entering a phase of development where efficiency is becoming a concern. I don't think it's a good idea to have to read a file on a physical disk ever single time I wish to access the database (very often). I was considering storing the connection string in Application["ConnectionString"]. So the code would be public static string GetConnectionString { if (Application["ConnectionString"] == null) { XmlDocument doc = new XmlDocument(); doc.Load(HttpContext.Current.Request.PhysicalApplicationPath + "bin/ServerEnvironment.xml"); XmlElement xe = (XmlElement) xnl[0]; switch (xe.InnerText.ToString().ToLower()) { case "local": connString = Settings.Default.ConnectionStringLocal; break; case "development": connString = Settings.Default.ConnectionStringDevelopment; break; case "production": connString = Settings.Default.ConnectionStringProduction; break; default: throw new Exception("no connection string defined"); } Application["ConnectionString"] = connString; } return Application["ConnectionString"].ToString(); } I didn't design the application so I figure there must have been a reason for reading the xml file every time (to change settings while the application runs?) I have very little concept of the inner workings here. What are the pros and cons? Do you think I'd see a small performance gain by implementing the function above? THANKS

  • .NET threading question

    - by MusiGenesis
    Is there any essential difference between this code: ThreadStart starter = new ThreadStart(SomeMethod); starter.Invoke(); and this? ThreadStart starter = new ThreadStart(SomeMethod); Thread th = new Thread(starter); th.Start(); Or does the first invoke the method on the current thread while the second invokes it on a new thread?

  • streaming XML serialization in .net

    - by Luca Martinetti
    Hello, I'm trying to serialize a very large IEnumerable<MyObject> using an XmlSerializer without keeping all the objects in memory. The IEnumerable<MyObject> is actually lazy.. I'm looking for a streaming solution that will: Take an object from the IEnumerable<MyObject> Serialize it to the underlying stream using the standard serialization (I don't want to handcraft the XML here!) Discard the in memory data and move to the next I'm trying with this code: using (var writer = new StreamWriter(filePath)) { var xmlSerializer = new XmlSerializer(typeof(MyObject)); foreach (var myObject in myObjectsIEnumerable) { xmlSerializer.Serialize(writer, myObject); } } but I'm getting multiple XML headers and I cannot specify a root tag <MyObjects> so my XML is invalid. Any idea? Thanks

    - by Matthieu
    Hi, I'm looking for a tool that allows me to analyze the compilation of a VS Solution (about 30 VS projects inside). I would like to know after the global solution compilation, which projets fail and forward errors to developers. Of course, I could analyze the compilation report... but I'm pretty sure that great tools are available ! What is for you the best one ? Thanks a lot !

  • Deserializing JSON in WCF throws xml errors in .Net 4.0

    - by Syg
    Hi there. I'm going slidely mad over here, maybe someone else can figure out what's going on here. I have a WCF service exposing a function using webinvoke, like so: [OperationContract] [WebInvoke(Method = "POST", BodyStyle = WebMessageBodyStyle.Wrapped, RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json, UriTemplate = "registertokenpost" )] void RegisterDeviceTokenForYoumiePost(test token); The datacontract for the test class looks like this: [DataContract(Namespace="Zooma.Test", Name="test", IsReference=true)] public class test { string waarde; [DataMember(Name="waarde", Order=0)] public string Waarde { get { return waarde; } set { waarde = value; } } } When sending the following json message to the service, { "test": { "waarde": "bla" } } the trace log gives me errors (below). I have tried this with just a string instead of the datatype (void RegisterDeviceTokenForYoumiePost(string token); ) but i get the same error. All help is appreciated, can't figure it out. It looks like it's creating invalid xml from the json message, but i'm not doing any custom serialization here. The formatter threw an exception while trying to deserialize the message: Error in deserializing body of request message for operation 'RegisterDeviceTokenForYoumiePost'. Unexpected end of file. **Following elements are not closed**: waarde, test, root.</Message><StackTrace> at System.ServiceModel.Dispatcher.OperationFormatter.DeserializeRequest(Message message, Object[] parameters)

  • Lucene (.NET) Document stucture and performance suggestions.

    - by Josh Handel
    Hello, I am indexing about 100M documents that consist of a few string identifiers and a hundred or so numaric terms.. I won't be doing range queries, so I haven't dugg too deep into Numaric Field but I'm not thinking its the right choose here. My problem is that the query performance degrades quickly when I start adding OR criteria to my query.. All my queries are on specific numaric terms.. So a document looks like StringField:[someString] and N DataField:[someNumber].. I then query it with something like DataField:((+1 +(2 3)) (+75 +(3 5 52)) (+99 +88 +(102 155 199))). Currently these queries take about 7 to 16 seconds to run on my laptop.. I would like to make sure thats really the best they can do.. I am open to suggestions on field structure and query structure :-). Thanks Josh PS: I have already read over all the other lucene performance discussions on here, and on the Lucene wiki and at lucid imiagination... I'm a bit further down the rabbit hole then that...

  • .NET Remoting Connecting to Wrong Host

    - by Dark Falcon
    I have an application I wrote which has been running well for 4 years. Yesterday they moved all their servers around and installed about 60 pending Windows updates, and now it is broken. The application makes use of remoting to update some information on another server (10.0.5.230), but when I try to create my remote object, I get the following exception: Note that it is trying to connect to 127.0.0.1, not the proper server. The server (10.0.5.230) is listening on port 9091 as it should. This same error is happening on all three terminal servers where this application is installed. Here is the code which registers the remoted object: public static void RegisterClient() { string lServer; RegistryKey lKey = Registry.CurrentUser.OpenSubKey("SOFTWARE\\Shoreline Teleworks\\ShoreWare Client"); if (lKey == null) throw new InvalidOperationException("Could not find Shoretel Call Manager"); object lVal = lKey.GetValue("Server"); if (lVal == null) throw new InvalidOperationException("Shoretel Call Manager did not specify a server name"); lServer = lVal.ToString(); IDictionary props = new Hashtable(); props["port"] = 0; string s = System.Guid.NewGuid().ToString(); props["name"] = s; ChannelServices.RegisterChannel(new TcpClientChannel(props, null), false); RemotingConfiguration.RegisterActivatedClientType(typeof(UpdateClient), "tcp://" + lServer + ":" + S_REMOTING_PORT + "/"); RemotingConfiguration.RegisterActivatedClientType(typeof(Playback), "tcp://" + lServer + ":" + S_REMOTING_PORT + "/"); } Here is the code which calls the remoted object: UpdateClient lUpdater = new UpdateClient(Settings.CurrentSettings.Extension.ToString()); lUpdater.SetAgentState(false); I have verified that the following URI is passed to RegisterActivatedClientType: "tcp://10.0.5.230:9091/" Why does this application try to connect to the wrong server?

  • asp.net mvc: What is the correct way to return html from controller to refresh select list?

    - by Mark Redman
    Hi, I am new to ASP.NET MVC, particularly ajax operations. I have a form with a jquery dialog for adding items to a drop-down list. This posts to the controller action. If nothing (ie void method) is returned from the Controller Action the page returns having updated the database, but obviously there no chnage to the form. What would be the best practice in updating the drop down list with the added id/value and selecting the item. I think my options are: 1) Construct and return the html manually that makes up the new <select> tag [this would be easy enough and work, but seems like I am missing something] 2) Use some kind of "helper" to construct the new html [This seems to make sense] 3) Only return the id/value and add this to the list and select the item [This seems like an overkill considering the item needs to be placed in the correct order etc] 4) Use some kind of Partial View [Does this mean creating additional forms within ascx controls? not sure how this would effect submitting the main form its on? Also unless this is reusable by passing in parameters(not sure how thats done) maybe 2 is the option?] UPDATE: Having looked around a bit, it seems that generating html withing the controller is not a good idea. I have seen other posts that render partialviews to strings which I guess is what I need and separates concerns (since the html bits are in the ascx). Any comments on whether that is good practice.

  • ASP.NET Memory Usage in IIS is FAR greater than in DevEnv. Is this normal?

    - by Tom
    Greetings! I have an ASP.NET app that scrapes data from a handful of external pages, parses the relevant bits and displays them in a table. Total data retrieved is 3-4MB and the resulting page is about 1MB. I am using synchronous WebRequest GetResponse for the retrieval, but the same problem existed using an asynchronous BeginGetResponse/EndGetResponse process. There is no database access, no session storage, no caching, but an in-memory list of about 100 objects (total 1MB of data), plus a good amount of AJAX (AjaxControlToolkit). This issue appears on the very first run of the app, even if I have restarted IIS. The issue: When I run the app on my dev computer, the maximum commit charge is about 1.5GB. The biggest user, measured by Task Manager's VM Size, is WebDev.WebServer.exe (600MB). The app runs perfectly. When I run it on my rent-a-server (IIS 7.5, 1GB RAM), the maximum commit charge is over 3.8GB. The biggest user is w3wp.exe at 2.7GB. IIS grinds to a halt and spits out a timed-out error page. Given my limited server budget and the hope of having multiple simultaneous users, I'm kind of in a panic. Is this normal? If I bump the server RAM up to 4GB, will that be enough? Will multiple users require even more memory? Could the culprit be AJAX or the list of objects? Thanks for any insight you can provide.

  • How to make a class serializable without Serializable attibute in .net

    - by Ashwani K
    Hello All: I have one debugger visualizer for seeing list of class object in the form of data table. But the limitation for the code is that the class should be serializable i.e. should be marked as [Serializable] and if the class is not marked Serializable then the debugger crashes. So, can anybody tell me how to make a class Serializable at run time if the class is not marked Serializable. Thanks Ashwani

  • .NET CF on Windows CE - problem with filtering system messages

    - by mack369
    Hello, I'm trying to get every windows message that tells that the user has touched the screen. It works everywhere, except the button, when it is disabled. It seems that the application doesn't get any message when clicked on disabled control. I'm using OpenNetCF Application2 class for filtering messages: Application2.AddMessageFilter(Device.PowerManager); Application2.Run(new MainForm()); PowerManager class contains a following method (as required by IMessageFilter interface): public bool PreFilterMessage(ref Microsoft.WindowsCE.Forms.Message m) { log.DebugFormat("windows message {0} - 0x{0:X}", m.Msg); if (m.Msg == 0x0201 || m.Msg == 0x8001 || m.Msg == 0x0005) { return this.ResetPowerManager(); } return false; } in the log file there is no indication of a windows message when clicking on disabled button. I'm wondering how is it possible and how can I get this message.

  • What's the best practice to setup testing for ASP.Net MVC? What to use/process/etc?

    - by melaos
    hi there, i'm trying to learn how to properly setup testing for an ASP.Net MVC. and from what i've been reading here and there thus far, the definition of legacy code kind of piques my interests, where it mentions that legacy codes are any codes without unit tests. so i did my project in a hurry not having the time to properly setup unit tests for the app and i'm still learning how to properly do TDD and unit testing at the same time. then i came upon selenium IDE/RC and was using it to test on the browser end. it was during that time too that i came upon the concept of integration testing, so from my understanding it seems that unit testing should be done to define the test and basic assumptions of each function, and if the function is dependent on something else, that something else needs to be mocked so that the tests is always singular and can be run fast. Questions: so am i right to say that the project should have started with unit test with proper mocks using something like rhino mocks. then anything else which requires 3rd party dll, database data access etc to be done via integration testing using selenium? because i have a function which calls a third party dll, i'm not sure whether to write a unit test in nunit to just instantiate the object and pass it some dummy data which breaks the mocking part to test it or just cover that part in my selenium integration testing when i submit my forms and call the dll. and for user acceptance tests, is it safe to say we can just use selenium again? Am i missing something or is there a better way/framework? i'm trying to put in more tests for regression testing, and to ensure that nothing breaks when we put in new features. i also like the idea of TDD because it helps to better define the function, sort of like a meta documentation. thanks!! hope this question isn't too subjective because i need it for my case.

  • Excel Autofilter in VB.NET

    - by Fabri
    In my application I'm exporting an Excel file by getting the layout of a HTML page. So, in my codebehind, I'm modifying the HTML layout and inserting itens on it like if it was a webpage. Doing it that way, I don't need to use any external library and, as the data I'm exporting is just a table, I don't need nothing complex to handle it. My question is: there is a way to create an AutoFilter by just modifying the HTML tags? I mean, like if a put a < bColumn Name in the HTML, when exporting to Excel it will become Bold, it is possible to do the same thing with the AutoFilter?

  • Copy EXIF Metadata from TIF to JPEG in C# / VB.NET

    - by George
    Hello! I would really appreciate if you could shed light on this problem. I have 2 images, one was created from TIF file with metadata, the other is an in-memory image that will be saved as jpeg. Then I use this routine to transfer exif metadata from first image to the second one (that is from the one created from tif file to the in-memory image): For Each _p In image1.PropertyItems image2.SetPropertyItem(_p) Next And this works perfectly fine. All exif items are successfully copied. I confirmed this by using watches in debug mode. The problem comes when you save image2 as jpeg using this: Dim eps As EncoderParameters = New EncoderParameters(1) eps.Param(0) = New EncoderParameter(Encoder.Quality, 85) Dim ici As ImageCodecInfo = GetEncoderInfo("image/jpeg") image2.Save("C:\1.jpg", ici, eps) Only very few EXIF properties are saved with image2 jpeg file however, namely only camera model and camera maker. However If I save image2 as TIF, all properties from the original tif will be there. Can anyone explain why is that? Thanks.
