  • 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???

  • 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.)

  • 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.

  • 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)

  • 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.

  • How to server-side cache ASP.NET custom HttpHandler response

    - by Joel
    I've got a custom HttpHandler in my ASP.NET application, that basically builds and returns a javascript object. I have no experience with server-side caching, and my (possibly incompetent) google searches aren't returning anything basic enough to get me started. Could anyone provide a very simple example to give me an idea of how to access and use the server-side cache from a custom HttpHandler, or, leave some links to get me started? Thanks a lot. Additional info: I'm on IIS 6, and my code-behind is in C# (although a VB example would work as well).

  • 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. This error doesn't happen until I try to login. Here are the details of my error from IIS; I get the same error in VS: Parser Error Message: Password format specified is invalid. Source Error: Line 31: <add Line 32: name="SqlProvider" Line 33: type="System.Web.Security.SqlMembershipProvider" Line 34: connectionStringName="AdventureWorksConnectionString2" Line 35: applicationName="AddFileToSQL2" Source File: C:\Inetpub\AddFileToSQL2\web.config Line: 33 And the relevant contents of my web.config are: <connectionStrings> <add name="Master" connectionString="server=MSSQLSERVER;database=Master; Integrated Security=SSPI" providerName="System.Data.SqlClient" /> <add name="AdventureWorksConnectionString" connectionString="Data Source=SIDEKICK;Initial Catalog=AdventureWorks;Integrated Security=True" providerName="System.Data.SqlClient" /> <add name="AdventureWorksConnectionString2" connectionString="Data Source=SIDEKICK;Initial Catalog=AdventureWorks;Integrated Security=True; " providerName="System.Data.SqlClient" /> </connectionStrings> <system.web> <membership defaultProvider="SqlProvider" userIsOnlineTimeWindow="15"> <providers> <clear /> <add name="SqlProvider" type="System.Web.Security.SqlMembershipProvider" connectionStringName="AdventureWorksConnectionString2" applicationName="AddFileToSQL2" enablePasswordRetrieval="false" enablePasswordReset="true" requiresQuestionAndAnswer="true" requiresUniqueEmail="false" passwordFormat="encrypted" /> </providers> </membership> <!-- Set compilation debug="true" to insert debugging symbols into the compiled page.

The Network Service account has SELECT, EXECUTE, INSERT, UPDATE access to this database. But one problem I see is that all of the tables in this database are empty except for aspnet_SchemaVersions, which just has 2 records (common and membership). Is this right? I added users and roles via ASP.NET Configuration wizard, and I believe I set this up correctly since I followed the Microsoft tutorial at http://msdn.microsoft.com/en-us/library/ms998347.aspx.

  • .net activeX object

    - by Ali YILDIRIM
    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.

  • Response.TransmitFile() with UNC share (ASP.NET)

    - by frankadelic
    In the comments of this page: http://msdn.microsoft.com/en-us/library/12s31dhy.aspx ..it says that TransmitFile() cannot be used with UNC shares. As far as I can tell, this is the case; I get this error in Event Log when I attempt it: TransmitFile failed. File Name: \\myshare1\e$\file.zip, Impersonation Enabled: 0, Token Valid: 1, HRESULT: 0x8007052e The suggested alternative is to use WriteFile(), however, this is problematic because it loads the file into memory. In my application, the files are 200MB, so this is not going to scale. Is there a method in ASP.NET for streaming files to users that's: scalable (doesn't read entire file into RAM or occupy ASP.NET threads) works with UNC shares Mapping a network drive as a virtual directory is not an option for us. I would like to avoid copying the file to the local web server as well. Thanks

  • Asp.net RenderControl method not rendering autopostback for dropdownlist

    - by Tanya
    Hi all, i am bit confused as to why asp.net does not render a dropdownlist with the autopostback property set to true when using the RenderControl method. eg Dim sw As New IO.StringWriter Dim tw As New HtmlTextWriter(sw) Dim table As New Table table.Rows.Add(New TableRow) Dim tr As TableRow = table.Rows(0) tr.Cells.Add(New TableCell) Dim tc As TableCell = tr.Cells(0) Dim ddlMyValues As New DropDownList ddlMyValues.ID = "ddl1" ddlMyValues.Items.Add("Test1") ddlMyValues.Items.Add("Test2") ddlMyValues.Items.Add("Test3") ddlMyValues.AutoPostBack = True tc.Controls.Add(ddlMyValues) table.RenderControl(tw) Debug.WriteLine(sw.ToString) my output renders the dropdown list without the onchange="javascript:setTimeout('__doPostBack(\ddl1\',\'\')', 0)" that is generated by asp.net when using the dropdownlist normally. Is there a work around to this?

  • How to perform insert and update with Ado.net dataservices (EF and Inheritance)

    - by Thurein
    Hi, I have an entity model, in which I have a table per type inheritance. There are 3 types, first, Contact, which I defined as abstract in my EF model and the rest are Company and person types which are derived from contact type. Is it possible to perform an insert using ado.net dataservice and asp.net ajax library? I was trying the following client code : dataContext.insertEntity(person, "Contacts"); I was getting this response from server : Error processing request stream. Type information must be specified for types that take part in inheritance. Thanks.

  • Thrift and .NET - Is this is right combination?

    - by Vadi
    I've been evaluating various technologies for a Social Networking project. The Thrift kind of interested me to evaluate. The advantage I see using Thrift is I can even come with C++ services when the computation in any such business is huge and may not fits with .NET etc., Please suggest your comments. My Questions: Is the open-sourced one is production-ready? Is it the right stack for services layer to choose when the application (GUI) is primarily gets developed in ASP.NET and DB is SQL Server? Is there any other caveats

  • How to use HTML-5 data-* attributes in ASP.NET MVC

    - by sleepy
    I am trying to use HTML5 data- attributes in my ASP.NET MVC 1 project. (I am a C# and ASP.NET MVC newbie.) <%= Html.ActionLink("« Previous", "Search", new { keyword = Model.Keyword, page = Model.currPage - 1}, new { @class = "prev", data-details = "Some Details" })%> The "data-details" in the above htmlAttributes give the following error: CS0746: Invalid anonymous type member declarator. Anonymous type members must be declared with a member assignment, simple name or member access. It works when I use data_details, but I guess it need to be starting with "data-" as per the spec. My questions: Is there any way to get this working and use HTML5 data attributes with Html.ActionLink or similar Html helpers ? Is there any other alternative mechanism to attach custom data to an element? This data is to be processed later by JS.

  • Is .NET support for Win32 Code Interop?

    - by Usman
    Hello, I need to InterOp Win32 code (unmanaged Win32 DLL's and Exe) completely with .NET. I need to call Win32 unmanaged code(DLL exported functions) at runtime i.e (knowing the types of data types in Win32 signatures and need to pass data according to that type at runtime). This is 100% possible in case of COM. You can convert COM unmanaged code to managed assemblies using tlbimp.exe and use now reflection API to work with those managed types(actual were unmanaged types now converted managed using tlbimp). But same functionality I need to get in terms of Win32(i.e) in .NET framework. How?? I know MS provided Export table reading API ..but I couldn't find exact API for InterOp of Win32 unmanaged code Regards

  • ASP.NET MVC Response Filter + OutputCache Attribute

    - by Shane Andrade
    I'm not sure if this is an ASP.NET MVC specific thing or ASP.NET in general but here's what's happening. I have an action filter that removes whitespace by the use of a response filter: public class StripWhitespaceAttribute : ActionFilterAttribute { public StripWhitespaceAttribute () { } public override void OnResultExecuted(ResultExecutedContext filterContext) { base.OnResultExecuted(filterContext); filterContext.HttpContext.Response.Filter = new WhitespaceFilter(filterContext.HttpContext.Response.Filter); } } When used in conjunction with the OutputCache attribute, my calls to Response.WriteSubstitution for "donut hole caching" do not work. The first and second time the page loads the callback passed to WriteSubstitution get called, after that they are not called anymore until the output cache expires. I've noticed this with not just this particular filter but any filter used on Response.Filter... am I missing something? I also forgot to mention I've tried this without the use of an MVC action filter attribute by attaching to the PostReleaseRequestState event in the global.asax and setting the Response.Filter value there... but still no luck.

  • How do I use custom member properties for people on my .NET website

    - by Jordan S
    I am trying to make an asp.net website using Visual web dev and C# that accesses data in an SQL database. For my site, I need to be able to save and access additional user properties such as age and gender. I have been playing around with the built in .NET Login tools but I don't understand how to keep track of the additional properties (age, gender...) I could store all the users information in my own database but how do I correlate the users data in my DB to the usernames in the member database that is automatically created?

  • Graphical Countdown in Jquery/Javascript/ASP.NET

    - by Eduard Schlechtinger
    Hi designers/developers, I am looking for a way of graphically showing a countdown. I am working for a large Hospital and have written an Ambulance page that shows ambulance arriving in a datagrid with the time of arriving at the hospital in minutes and seconds (plus other info). They have asked me for somehow visually representing the information, so it fits with there other visually appealing Emergency Department web application (e.g. progress bar or something better): 1) Can somebody show me (visually appealing) design examples on how this could be done 2) Are there solutions in .Net (ASP.net or JQuery or Javascript) since this is our preferred technology Thanks so much!
