• Visual C# Intellisense breaks on Indexer of C5 generic collection library

  Hello, I noticed a problem when trying to use indexers of the great C5 Collection Library ( http://www.itu.dk/research/c5/ ) . The library makes much better use of Interfaces than the collection classes in System.Collections.Generic and work fine most of the time, except when one tries to access members of the type stored in the collection class via the Indexer. So, to illustrate, when I have myArrayList defined as C5.ArrayList<string>, type myArrayList.First and then type the dot I get the list of available members of the string class shown by Intellisense. Just as it should be. However, when I do the same with myArrayList[0] and then type the dot, nothing happens. This is quite annoying. It appears to me that the problem might be ...Show All

• Windows Forms Advanced Cell formatting - DataGridViewColumn

  Using StringTo() method for Formatting cell within the DataGridViewColumn: I have created custom DataGridViewColumn and DataGridViewCell based on user defined data type. It stores float numbers that represent various strings. For example number 0.001 represents string "00", number 1.002 is formatted as "1T", number 0.5 is "05" while integers are formatted as they are (100 => "100") etc. Override ToString() method is used to provide the conversion from a number to a string. I now need to force my custom column to display the formatted strings instead of the float values that I stored in database, i.e. when I type 0.001 into the cell, I need to display "00" but the value of the c ...Show All

• Software Development for Windows Vista sAPO property project compile error

  Hello, guys. I'm trying to compile sAPO property project in WDK 5472. But everytime I do that, I got the error message that "PKEY_Device_FriendlyName" is not defined.

• Game Technologies: DirectX, XNA, XACT, etc. Save projects under new filenames?

  XNA Game Studio doesn't have a command to save projects under new filenames or make copies of projects. For example, create a new project while going through a tutorial from a web site. Is it possible to save projects under new filenames or make copies of projects I'm not sure if copying project folders will work because there is "Namespace" parameter at the top of the source code and if there are any files in any folders that are used by the program that I'm writing, the program may not find the files when running. ...Show All

• Visual Studio Impossible to uninstall GAT or GAX

  Hello, I have an exception when I try to repair or to remove the GAT, because there is problems with registered guidance packages which don't exist yet. So I tried to manually unregister all the guidance package, following the instructions on the Clarius's Blog. I unregistered all the guidance packages found in the manifest file (RecipeFramework.xml). But if there is other registered guidance packages unknown (because I have no more the files), it is impossible to unregister them because I don't know their name and GUID. So it is always impossible to repair or remove GAT ! The exception said "The manifest file doesn't contain an entry for the guidance package Guidance Package Development". Usually, in this case, you instal ...Show All

• .NET Development Cryptic exception...A call to SSPI failed...

  Hi All, Been working this issue for a few days now, here's the deal. I have a bit of VB.NET code that uses an SslStream object to communicate with a Java application over SSL. The Java application uses JSSE to facilitate SSL. The VB.NET SslStream code works fine on any machine thus far except for one. On this particular machine, when the VB.NET code calls the AuthenticateAsClient method, the following exception is raised: System.Security.Authentication.AuthenticationException: {"A call to SSPI failed, see inner exception."} Data: {System.Collections.ListDictionaryInternal} HelpLink: Nothing InnerException: {"Invalid flags specified"} Message: "A call to SSPI failed, see inner exception."

• Visual Studio SP1 for ReportViewer Redistributable?

  Hi Everyone. Now that VS.2005 SP1 is out and seems to include an updated ReportViewer control, is there an update to the ReportViewer Redistributable with those same fixes Our product installs this redistributable silently, and we render reports locally (i.e. RDLC), so installing the full Visual Studio service pack would not help us.
