  • Very slow startup of ASP.NET applications

    - by Conrad
    I have an ASP.NET applications with quite small number of pages. The problem I see is that the startup time is quite slow. As far as I can tell, most of the time is spent in JIT. Pre-compiling the applications seem not very helpful in reducing the #methods JIT as reported thru PerfMon. Does anybody know what I can do to reduce the startup time further? Is it true that there is no way to pre-jit an ASP.NET application using NGEN?

  • Getting a .Net remoting service accessible with IP v6 and IP v4

    - by jon.ediger
    My company has an existing .Net Remoting service that listens on a port, fronting interfaces used by external systems. This all works great with IP v4 based communications. However, this service now needs to support both IP v4 communications and IP v6 communications. I have found info that the system.runtime.remoting section of the app.config should include two channels as follows: <channel ref="tcp" name="tcp6" port="9000" bindTo="[::]" /> <channel ref="tcp" name="tcp4" port="9000" bindTo="0.0.0.0" /> I've tried this. For communications to this service and a direct response back, this works great. Some of the communications instead return a stream back, either for uploading or downloading large files. These calls fail with the an ArgumentException: IPv4 address 0.0.0.0 and IPv6 address ::0 are unspecified addresses that cannot be used as a target address. Parameter name: hostNameOrAddress How should these config values be modified so that the client will know how to communicate back to the .Net remoting service?

  • Random "Not Found" error with Silverlight accessing ASP.NET Web Services

    - by user245822
    I'm developing an application with Silverlight 3 and ASP.NET Web Services, which uses Linq to SQL to get data from my SQL Server database. Randomly when the user causes an action to get information from any of my web service methods, Silverlight throws the exception "The remote server returned an error: NotFound.", of type "CommunicationException", with the InnerException status of "System.Net.WebExceptionStatus.UnknownError". Almost 10% of requests gets this error. If the user tries to get the same information again, normally the request has no erros and the user gets the data. When debugging in Visual Studio only Silverlight stops on the exception, and I see no reason for the web service not being found.

  • WCF REST vs. ADO.NET Data Services

    - by ray247
    Hi there, Could someone compare and contrast on WCF Rest services vs. ADO.NET Data Services? What is the difference and when to use which? Thanks, Ray. Edit: thanks to the first answer, just to give a bit background on what I'm looking to do: I have a web app I plan to put in the cloud (someday), the DAL is built with ADO.NET Entity Framework. And, I need to figure which web service data access technology would best fit my case.

  • Using Monotouch with Google .NET APIs

    - by Bryan
    I am using Mike Bluestein's article, http://mikebluestein.wordpress.com/2009/09/27/using-monotouch-with-the-net-library-for-the-google-data-api/, to build an application that communicates with the google APIs. When I try to add references to my project, the imported projects say "incompatible target framework: v2.0". I can change version to 1.0, 3.0, or 3.5 with the same results. If I add the .dll to the monotouch project I get a compilation error - monotouch failed with no output 134. Any suggestions?

  • Multiple skins in ASP.NET MVC using StringTemplate

    - by Jamie
    I am considering the StringTemplate view engine for my ASP.NET MVC application. This application will be built with one skin, but I then expect many more, often very similar skins to be developed for it. This is primiarly the reason for my choice of StringTemplate as the view engine, as there will be zero logic in the views. In my head, I envisaged having each skin in a directory under the 'Views' directory in the folder structure, then maintaining a data structure which maps hostnames to skin directories. An obvious disadvantage of this approach is that I will have to explicitly specify my view files - an alternative might be to hack the implementation of the View() method to change the /views/controller/action standard path and insert an extra layer. Is anyone aware of any examples of implementations along these lines using ASP.NET MVC and StringTemplate at present? Can anyone forsee any potential problems with my approach? Thanks in advance.

  • SQL - .NET - SqlParameters - AddWithValue - Are there any negative performance implications when Par

    - by hamlin11
    http://msdn.microsoft.com/en-us/library/system.data.sqlclient.sqlparametercollection.addwithvalue.aspx I'm used to adding sql parameters to a sqlCommand using the add() function. This allows me to specify the type of the sqlParameter, but it requires another line to set the value. It's nice to use the AddWithValue function, but it skips the "specify the parameter type" step. I'm guessing this causes the parameters to be sent over as strings contained within single quotes (''), but I'm not sure. Is this the case, and does this cause significantly slower performance of the stored procedures? Note: I understand that it is nice to validate user data on the .NET side of things by specifying the data type for params -- I'm only concerned about reflection-type overhead of AddWithValue either on the .NET or SQL side.

  • Integrating FedEx Web Services into .Net, stuck at step 1

    - by Matt Dawdy
    I'm signed up, I've downloaded sample code, I've got a WSDL...and yet I have no idea how to get this stuff into my existing .Net application. The WSDL was in a zip file, not a URL so I can't just "Add Web Reference." I've run the wsdl tool from the .Net command prompt, and it made a nice class for me...yet dropping that into my web_reference folder doesn't give me any kind of instantiatable class. I know I'm missing something stupid. Can someone point me in the right direction please?

  • Asp.NET MVC Areas

    - by RailRhoad
    So we finally got "areas" in our ASP.NET MVC framework! I'm able to get them up and going but one thing that bothers me is the amount of development servers it instantiates! So I currently have 6 areas, and when I run it I get 6 dev server instances running. Is this really necessary? MSDN is having me setup these areas as seperate web apps, couldn't we get these down into class libraries somehow?

  • How to structure VB.NET windows forms applications

    - by Jon
    What is the best way to structure a VB.NET windows forms application so that code can be reused and the app can be extended easily. I used to create lots of new forms. This lead to lots of repeated code and forms which did similar things. Now, for forms which do similar jobs, such as view/edit/delete items from a specific db table, I create a form with the required controls, have the form create an instance of a class with params such as a collection of the controls and a string containing the db table name. Then the individual controls call functions of the class. Advanced forms will inherit and extend this basic form class. 1) Has there already been work done in this area? 2) Are there books / articles available which discuss the options available on this topic? Thanks!

  • Debugging ASP.NET Strings Downloaded to Browser (Montréal instead of Montréal)

    - by jdk
    I'm downloading a vCard to the browser using Response.Write to output .NET strings with special accented characters. Mime type is text/x-vcard and French characters are appearing wrong in Outlook, for example Montréal;Québec .NET string shows as Montréal Québec in browser. I'm using this vCard generator code from CodeProject.com I've played with the System.Encoding sample code at the bottom of this linked MSDN page to convert the unicode string into bytes and then write the ascii bytes but then I get Montr?al Qu?bec (progress but not a win). Also I've tried setting content type to both us-ascii and utf-8 of the response. If I open the downloaded vCard in Windows Notepad and save it as ANSI text (instead of default unicode format) and open in Outlook it's okay. So my assumption is I need to cause download of ANSI charset but am unsure if I'm doing it wrong or have a misunderstanding of where to start. Update: Looking at the raw HTTP, it appears my French characters are being downloaded in the unexpected format so it looks like I need to do some work on the server side... (full size)

  • protobuf-net - backticks, Dictionaries & .proto files

    - by JosephH
    I'm trying to talk to a C# program that uses protobuf-net from an iphone using http://code.google.com/p/metasyntactic/wiki/ProtocolBuffers Unfortunately the .proto file I've been given (generated from the C# source code) includes an a line that protoc is rejecting: repeated Pair_Guid_List`1 Local = 6; It appears that this is because the source data is a C# Dictionary, with a Guid key and a class as the value. Is there a way to cope with this better? The protobuf-net version in use is r278.zip. (The C# sending and receiving these protobufs all works fine, it's just when we add the iphone into the mix that this becomes an issue.)

  • MVP on Asp.Net WebForms

    - by Nicolas Irisarri
    I'm not clear about this.... When having a gridview on the View, is the controller who has to set up the Data source, columns, etc? or I just have to expose the DataBinding stuff, fire it from the controller and let the html/codebehind on the view handle all the rendering and wiring up? To be more precise: on the view should I have private GridView _gv public _IList<Poco> Source { get {_gv.DataSource;} set {_gv.DataSource = value; _gv.DataBind();} } Or should it be (from http://stackoverflow.com/questions/153222/mvp-pattern-passive-view-and-exposing-complex-types-through-iview-asp-net-web) private GridView _datasource; public DataSource { get { return _datasource; } set { _datasource = value; _datasource.DataBind(); } } Maybe I'm having it all wrong .... Where can I find an example that is not a "Hello world" example on MVP for ASP.Net???

  • ModelBinding to and EntitySet (MVC2 & LinqToSQL)

    - by Myster
    Hi all There seems to be an issue with the default model binder when binding to an EntitySet causes the EntitySet to be empty. The problem is described here and here: Microsoft's response is: ... We have now fixed this and the fix will be included in .NET Framework 4.0. With the new behavior, if the EntitySet passed into Assign is the same object as the one its being assigned to, no action will occur. With a work around being to edit the code generated like so: public override EntitySet<Thing> Things { get { return this._Things; } set { //CORRECTION: _Things= new EntitySet<Thing>(); _Things.Assign(value); //WAS: this._Things.Assign(value); } } As you can imagine this is not ideal as you have to re-add the code every time, does anyone have a better solution?

  • How to use PDFBox 1.0 in .net / C# environment using IKVM

    - by Evan
    Id like to use PDFBox to generate PDF highlight files in my .net project. PDFBox states that it can be used in .net via IKVM http://www.pdfbox.org/userguide/dot_net.html BUT running ikvmc (latest version) to generate the DLLs on PDFBOX.1.0.0.jar generates a whole lot of NoClassDefFound warnings. How should I fix this, and what other DLLs do I need to include in my project? It seems as though file names have changed from the older documentation/articles I have read on the matter. thanks in advance.

  • Configuration Error ASP.NET password format specified is invalid

    - by salvationishere
    I am getting the above error in IIS 6.0 now when I browse my C# / SQL web application. This was built in VS 2008 and SS 2008 on a 32-bit XP OS. The application was working before I added Login controls to it. However, this is my first time configuring Login/password controls so I am probably missing something really basic.

  • .net activeX object

    Hi, I am trying to use my .net image editor user control as an activeX object in a web form. After internet search, I created a asp.net web site from VS2008 and added the following code <object classid="res/ImageEditor.dll#ImageEditor.Editor" height="400" width="400" id="myControl1" name="myControl1" > </object> <INPUT id="Button1" type="button" value="Btn" name="Btn" onclick="return Button1_onclick()"> </script> <script language=javascript> function Button1_onclick() { alert(document.getElementById("myControl1").WatermarkText); } </script> I have two problems 1-) When i first create the project i see the user control on browser but, after rebuilding the user control and changing the dll file at web site, the object no more appears on browser. Instead i see something like an error image. 2-) i can not access public properties. The user control is marked as "make com visible", and register for com is checked at properties.

  • Permission denied: cannot call non-public or static methods remotely.

    - by rstat1
    Ok I've found a solution to this particular error message on here already. But my case is slightly different. There are no "non-public" or "static" methods in my code. All are public. What I'm trying to do is pass a FrameworkElement (more specifically a web browser control) that was created in one process over to another process for display and use. Also I'm not using (and would to avoid using) any of the framework 3.5 addin stuff. Fails at the following line everytime. fe = FrameworkElementAdapters.ContractToViewAdapter(tab.ReturnBrowserObject) tab.ReturnBrowserObject returns an INativeHandleContract which the above line is suppose to convert to a FrameworkElement.
