  • Alternative to System.Web.HttpUtility.HtmlEncode/Decode?

    - by Jörg Battermann
    Is there any 'slimmer' alternative to the System.Web.HttpUtility.HtmlEncode/.Decode functions in .net 3.5 (sp1)? A separate library is fine.. or even 'wanted', at least something that does not pull in a 'whole new world' of dependencies that System.Web requires. I only want to convert a normal string into its xml/xhtml compliant equivalent (& back).

  • Is there a WinForm control inspector application?

    - by Simon Gillbee
    I'm looking for something that provides interactive meta-data about a running .NET WinForms application. Basically, I'd like to be able to hover over a running WinForms application and have the inspector highlight the various controls and let me inspect properties such as size, position, parent, etc. I could have sworn I've seen this somewhere, but all my searching is turning up nada.

    Is the SAP RFC SDK (wdtfuncs.ocx, wdtlog.ocx respectively Interop.SAPFunctionsOCX.dll, Interop.SAPLogonCtrl.dll) an acceptable / recommended way to connect (Microsoft) applications via RFCs with SAP ? Will there be a support and maintenance of the SDK in the future (especially in ECC 6.0) ? Are there people who use these controls in .NET applications ?

  • Invoking a WCF service using claims based authentication

    - by ashwnacharya
    I have a WCF service deployed in a server machine. We are using claims based authentication to authenticate the WCF service caller. The WCF service is restricted by using IIS Authorization rules. How do I programmatically invoke the WCF service using .NET? The client app uses a proxy generated using SVCUtil. calling the service reads the credentials from a configuration file (not the app.config file, in fact the client application does not have a *.config file).

  • Is there a way of recover from an Exception in Directory.EnumerateFiles ?

    - by Magnus Johansson
    In .NET 4, there's this Directory.EnumerateFiles() method with recursion that seems handy. However, if an Exception occurs within a recursion, how can I continue/recover from that and continuing enumerate the rest of the files? try { var files = from file in Directory.EnumerateFiles(@"c:\", "*.*", SearchOption.AllDirectories) select new { File = file }; Console.WriteLine(files.Count().ToString()); } catch (UnauthorizedAccessException uEx) { Console.WriteLine(uEx.Message); } catch (PathTooLongException ptlEx) { Console.WriteLine(ptlEx.Message); }

  • Why does mage not generate a compatibleFrameworks attribute

    - by Kev Hunter
    We are using mage to generate our applications manifests as part of our build process. Upon upgrading to .Net 4 we now find it generates an invalid manifest. The reason is there is no compatibleFrameworks attribute being set in the application manifest which we generate every build. Is there anyway we can make Mage add this element of should we only ever update existing manifests

  • How to use HttpContext.Current on asynchronous threads?

    - by Eran Betzalel
    I've a schedule tasks mechanism (very similar to DotNetNuke's) in my business logic library (a DLL that is used by ASP.Net website). When I use HttpContext.Current inside on of these tasks, it returns with a null value, because the current async thread (or task) was not initiated from a user's request. How can I use HttpContext.Current in these asynchronous threads? P.S - I think my question is more best-practices related than technical.

  • Encoding Special Characters For Outlook HTML Email

    - by n0chi
    I have an asp.net / C# page which takes a comment, and then emails that comment. Sometimes when the user enters "&" in the comment, the comment is being truncated. So for example if the comment is "test & test" the email only sends out "test ". I have tried HttpUtility.HtmlEncode - but it looks like the issue is on the outlook side and not on the C# side.

  • WatiN or Selenium?

    - by David Thomas Garcia
    I'm going to start building some automated tests of our presentation soon. It seems that everyone recommends WatiN and Selenium. Which do you prefer for automated testing of ASP.NET web forms? Why did that product work better for you? As a side note, I noticed that WatiN 2.0 has been in CTP since March 2008, is that something to be concerned about?

  • MVVM Light Toolkit throws an System.IO.FileLoadException

    - by joebeazelman
    I'm running VS 2010 along with Expression Blend 4 beta.

  • Extend linq-to-sql partial class to avoid writing a property?

    - by Curtis White
    I have a linq-to-sql class. I have a property "Password" for which I want to call the underlying ASP.NET Membership provider. Thus, I do not want this property written out directly but via my own code. I basically want to create a facade/proxy for this property such that I may use the underlying membership provider or a custom stored procedure. I want to accomplish without modifying the LINQ-TO-SQL designer generated code, if at all possible.
