• web.config inheritance problem

  - by abszero

  Hello everyone, I am having an issue when I try and prevent inhertiance from a parent web.config down to a child specifically related to the node. My parent web.config contains about a dozen appSettings values while my child web.config contains none. Now, I originally began wrapping around only my system.net, web, etc nodes however when I ran my child application I recieved the following error: The configuration section 'appSettings' cannot be read because it is missing a section declaration I really wasn't sure what this meant and a google search didn't yield me any decent results so I attempted to move the location node to also encompass the field in my parent web.config but to no avail. My child web.config is pretty vanilla so I am not sure what the problem is. Any help you can provide would be greatly appreciated! Thanks. The child config is completely vanilla except for the addition of an Xml Namespace and a 'clear' in the config sections as follows: <configuration xmlns="http://schemas.microsoft.com/.NetConfiguration/v2.0"> <configSections> <clear /> <sectionGroup name="system.web.extensions" type="System.Web.Configuration.SystemWebExtensionsSectionGroup, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"> <sectionGroup name="scripting" type="System.Web.Configuration.ScriptingSectionGroup, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"> <section name="scriptResourceHandler" type="System.Web.Configuration.ScriptingScriptResourceHandlerSection, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" requirePermission="false" allowDefinition="MachineToApplication"/> <sectionGroup name="webServices" type="System.Web.Configuration.ScriptingWebServicesSectionGroup, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"> <section name="jsonSerialization" type="System.Web.Configuration.ScriptingJsonSerializationSection, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" requirePermission="false" allowDefinition="Everywhere" /> <section name="profileService" type="System.Web.Configuration.ScriptingProfileServiceSection, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" requirePermission="false" allowDefinition="MachineToApplication" /> <section name="authenticationService" type="System.Web.Configuration.ScriptingAuthenticationServiceSection, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" requirePermission="false" allowDefinition="MachineToApplication" /> <section name="roleService" type="System.Web.Configuration.ScriptingRoleServiceSection, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" requirePermission="false" allowDefinition="MachineToApplication" /> </sectionGroup> </sectionGroup> </sectionGroup> </configSections> The error in question is thrown at The parent web.config is far from vanilla as it is part of an Umbraco install.

• WPF command/click argument

  - by Joel Barsotti

  So I have a background in ASP.NET where a button could have a click handler or a command handler and then a command argument. That pattern was great for when you had a bunch of buttons that basically needed to execute the same block of code with only a slightly different argument. Is there a collary in WPF? From what I've seen of the Command in WPF is that it revolves around an action that is independent of the control that invokes it (and still doesn't provide a way to provide an argument). Which is not really what I need.

• mvc presentation model best-practices

  - by Andrew Florko

  Hello, everybody How do you usually convert business objects to presentation? For example: Business object Person { Id, FirstName, LastName, Patronymic ... } should be presented as "LastName F. P. " in html layout. We use Presentation classes hierarchy to represent data ready for output from Business model. Questions: Will you keep presentation model completely separated from Business Model. For example, can strong-typed views (MVC ASP.NET) aggregate formatted business data as well as raw business objects (that leads toward <%=Html.Encode(PersonHelper.ToShort(Model.Person))% html layout injections) What architecture layer do you choose for conversion (mvc controllers that formats business data from business layer, for instance). Thank you in advance

• How to remove check digit from a barcode

  - by Teddy

  Hi. I have barcodes generated with Code 39 symbology. Some of the barcodes contain check digit, and some does not. So, how can I prevent barcode scanner to pass the check digit to the pc? Or is there another way I can check if the barcode has a check digit in .Net? For example, the encoded data is 1642, but the the barcode scanner reads 16425 and I might have data a barcode with encoded data 16425. I need to distinguish both cases either in the code, or in the barcode scanner. Thanks.

• "Quoted-printable line longer than 76 chars" warning when sending HTML E-Mail

  - by Chris Roberts

  Hi, I have written some code in my VB.NET application to send an HTML e-mail (in this case, a lost password reminder). When I test the e-mail, it gets eaten by my spam filter. One of the things that it's scoring badly on is because of the following problem: MIME_QP_LONG_LINE RAW: Quoted-printable line longer than 76 chars I've been through the source of the e-mail, and I've broken each line longer than 76 characters into two lines with a CR+LF in between, but that hasn't fixed the problem. Can anyone point me in the right direction? Thanks!

• Best and simple data structure

  - by anshu

  I am trying to create the below matrix in my vb.net so during processing I can get the match scores for the alphabets, for example: What is the match for A and N?, I will look into my inbuilt matrix and return -2 Similarly, What is the match for P and L?, I will look into my inbuilt matrix and return -3 Please suggest me how to go about it, I was trying to use nested dictionary like this: Dim myNestedDictionary As New Dictionary(Of String, Dictionary(Of String, Integer))() Dim lTempDict As New Dictionary(Of String, Integer) lTempDict.Add("A", 4) myNestedDictionary.Add("A", lTempDict) The other way could be is to read the Matrix from a text based file and then fill the two dimensional array. Thanks.

• Cufon JS is not loading

  - by UXdesigner

  I've developed a website in html/css and it works perfectly fine. Now I'm working with the coder, integrating this to a .NET framework, changing the website to .apsx instead of html, but during the build of the website, the only error that is marked is the load of Cufon , it simply can't load and the structure and syntax of all the commands are the same I used with the html site that actually works. There are no path problems so far. What do you guys think would be this problem ? Thank you for your kind help.

• How do you run PartCover with spaces in the path?

  - by nportelli

  I have a msbuild file that I'm trying to run from Hudson CI. It outputs like this "C:\Program Files\Gubka Bob\PartCover .NET 2\PartCover.exe" --target "C:\Program Files\Microsoft Visual Studio 9.0\Common7\IDE\MSTest.exe" --target-args "/noisolation" "/testcontainer:C:\CI\Hudson\jobs\Video Raffle\workspace\Source\VideoRaffleCaller\Source\VideoRaffleCaller.Test.Unit\bin\Debug\VideoRaffleCaller.Test.Unit.dll" --include "[VideoRaffleCaller*]*" --output "Coverage\partcover.xml" I get this error Invalid switch "raffle\workspace\source\videorafflecaller\source\videorafflecall er.test.unit\bin\debug\videorafflecaller.test.unit.dll". For switch syntax, type "MSTest /help" WTF? Looks like PartCover doesn't handle spaces in the --target-args well. Or am I missing some quotes somewhere? Has anyone gotten something like to to work?

• Scrambling URLS for dynamic data

  - by ggonsalv

  What is the best method to obfuscate the urls created in Dynamic Data? eg \Products\List.aspx?ProductId=2 could become \Products\List.aspx?x=UHJvZHVjdElkPTI= where "ProductId=2" is base 64 encoded to prevent casual snooping on \Products\List.aspx?ProductId=3 \Products\List.aspx?ProductId=4 etc...? I will probably have to inherit from an existing object and override some function The question is which object and what function GetActionPath of the Metamodel object seems interesting, but how does the DynamicRoute "{table}/{Action}.aspx" play in into it... Right now on Asp.net 1.1 site I use an custom implementation of the following code. http://www.mvps.org/emorcillo/en/code/aspnet/qse.shtml It is HTTPModule that uses regular expression to rewrite all the querystrings and also with reflection changes the Querystring collection with decoded values. So where is the hook to affect the change.

• Multi tenancy with Unity

  - by Savvas Sopiadis

  Hi everybody! I'm trying to implement this scenario using Unity and i can't figure out how this could be done: the same web application (ASP.NET MVC) should be made accessible to more than one client (multi-tenant). The URL of the web site will differentiate the client (this i know how to get). So getting the URL one could set the (let's call it) IConnectionStringProvider parameter (which will be afterward injected into IRepository and so on). Through which mechanism (using Unity) do i set the IConnectionStringProvider parameter at run time? I have done this in the past using Windsor & IHandlerSelector (see this) but it's my first attempt using Unity. Any help is deeply appreciated! Thanks in advance

• How can I use a custom ValidationAttribute to ensure two properties match?

  - by Brandon Linton

  We're using xVal and the standard DataAnnotationsValidationRunner described here to collect validation errors from our domain objects and view models in ASP.NET MVC. I'd like to have a way to have that validation runner identify when two properties don't match through the use of custom DataAnnotations. Right now I'm forced into doing it outside of the runner, this way: if (!(model.FieldOne == model.FieldTwo)) errors.Add(new ErrorInfo("FieldTwo", "FieldOne must match FieldTwo", model.FieldTwo)); My question is: can this be done using property-level validation attributes, or am I forced into using class-level attributes (in which case, I'd have to modify the runner...and my follow up question would be how best to retrieve them in that case). Thanks!

• Best package for basic web-based file manager

  - by alchemical

  I'm looking for a basic web-based file management application. It must have an affordable price, and fairly easy installation would be a plus. ASP.Net / IIS based would be easiest for me to work with. Basically, I'd like it to create a secure web site where myself and a few people can exchange various types of files, etc. I'm looking for a package I can install on my own server rather than a web-based service, as I think I can get more space at a good price point this way. I could go custom coding, but I figure this is such a generic need, there must be something already mature out there at a decent price. What has worked best for you?

• Custom filename in a rolling Log4Net logfile?

  - by Brett Rigby

  Hello We have a ASP .Net application whereby we use Log4Net to log details within the app - nothing new there - and the rolling log filenames are in the usual format of: rolling-log.txt rolling-log.txt.1 rolling-log.txt.2 etc. A each user of the application adds to the logfile, the logfile can be difficult to read for a specific user's case and so, we'd like to modify the config file somehow to record the user's log details individually, each writing to a specific file, e.g. <applicationId>rolling-log.txt <applicationId>rolling-log.txt.1 <applicationId>rolling-log.txt.2 etc. where is each user's unique application Id, made up of a five digit number, e.g. 12345rolling-log.txt Any ideas on the best way to implement this, assuming that it's possible? Cheers Brett

• Why does Visual Studio 2008 change namespace characters in a generated file?

  - by Fredrik

  Hello, I am working on a asp.net 3.5 project in sweden, where some of the namespaces include swedish characters, such as 'å', 'ä' and 'ö'. When building the project and generating the design-file, visual studio replaces these characters with some other strange characters. This only happens when the characters occur in a namespace or class name. If a field or variable contain a swedish character, everything works fine. To clarify, the strange character occur in the design file when a namespace and/or control contain swedish characters. Does anyone know why this happens and if there is a solution for the problem that doesn't mean changing the names of the namespaces? Sincerely, Fredrik

• Calling Oracle Function with "complex" return value from C#

  - by devdimi

  I have an Oracle function returning record defined in the package, so one can do: select a,b,c FROM my_function(...); Calling this oracle function from .NET is as simple as executing normal sql query. Unfortunately the function has to do updates now and when it is called like this Oracle complains that updates are not allowed within selects and that makes sense. So now I am left with the choice to change the function call or to split the function. Basically I have to get rid of the select in the function call and need something like this in C#: EXEC :var:= my_func(...); where the type of var is custom tuple defined in the package. I have already tried using ParameterDirection.ReturnValue without success. Does anyone have an idea?

• How do I debug a DLL from VS2008?

  - by GregH

  I have a program written in VB.Net (Visual Studio 2008) that uses a DLL written in Visual C++ by another developer. I'd like to be able to step in to the C++ code as my code makes calls to methods in the DLL. Since the DLL is it's own solution, I don't think it can be included in my solution/project. I tried putting the DLLs pdb file in the debug/bin directory with the rest of my build and pdb files. However, when I get to the point in stepping through my code, and it gets to the dll call, it just steps right over the dll code. Do I have to manually load symbols? Not sure what I'm doing wrong. Thanks.

So wont be able to monetize. It would be great for static ads. Any idea/inputs?

• Is mspec better with or without nunit?

  - by Byron Sommardahl

  I've seen mspec used with nunit on some blogs and discussions. In fact, most of the examples on the web that I've seen demonstrate mspec with some kind of nunit dependancy or integration. My team is attempting to use mspec without nunit on a new ASP.NET MVC2 project. We're not at the spec-writing stage yet, so I can't tell what is better. What it your experience with this? Are there benefits to using mspec with nunit? Without?

• Is it possible to Embed Gecko or Webkit in a Windows Form just like a WebView?

  - by Martín Marconcini

  Hi, I'd love to know if there is such thing as a Gecko.NET ;) I mean, just like we can embed a WebView and that is an "instance" of IE7 inside any Windows Forms application (and tell it to "navigateto (fancy_url);", I'd love to use FireFox or WebKit. Anybody tried this? UPDATE: Please bear in mind that although it is possible to embed gecko using the mentioned controls, it is still impossible to print while using gecko. UPDATE March 2010: It’s still not possible to print natively using GeckoFX, however a couple of methods exist that may be enough, depending upon what you’re trying to do. See: http://geckofx.org/viewtopic.php?id=796 for more information.

• Sharp Architecture for Winform apps?

  - by CF_Maintainer

  The Sharp Architecture Contrib seems to suggest it is possible. It seemed like they had a dependency on "PostSharp" which has now been replaced with Castle interceptors. Has anyone used the Sharp Architecture for a non Web project? How was the experience? Does that mean one is locked in with castle as the IoC container when using Sharp architecture for non web purposes? If not Sharp Architecture, then what are some of the favored application frameworks for the non web world [spring.NET?] ? If one were to start a green field Winforms app, what application framework would be desirable?
