• Visual Studio Team System Update of SettingValue.Value throws exception

  Hi, Following Dmitriy’s example ( http://forums.microsoft.com/msdn/ShowPost.aspx PostID=11246 ) I created an AddIn that analyzes an SDM diagram. During the analysis I’m trying to manipulate values of a particular SettingValue of a producer endpoint. This value is represented by a ComplexSettingValue[]. I have no problems to read and update existing elements of this array. But when I’m trying to reset it to a new array of this type because I want to add new entry I’m getting an “internal error” exception.     Any ideas Nel Dmitriy, Thanks a lot. It worked! Nel   P.S.

• .NET Development I need a simple MSDOS utility to count lines in a VC++ project.

  You know, something like the character, word, line count utility in UNIX. If you'd like the same wc command, you might try the GNU Utilities for Windows at http://unxutils.sourceforge.net/ . It includes wc.exe (along with many other Unix-like utilities).

• Software Development for Windows Vista WorkflowInstance.EnqueueItem Method

  Can I use this method to raise an External Event after an CallExternalMethodActivity has been finished and been persisted and the ListenActivity is waiting The question goes back to this entry ... If yes what would be expected as the second parameter public void EnqueueItem( IComparable queueName , object item , IPendingWork pendingWork , object workItem ); You really can't - as the second parameter is a type called MethodMessage - which is internal to System.Workflow.Activities.dll. You really only want to use EnqueueItem when *you* are the one creating the queue - not the Exter ...Show All

• Visual C# VS.NET 2005 RC1 -- Is clipboard ring missing from IDE?

  It used to be one of my favorite features! Formerly, from the C# (for example) code editor in the IDE, open the 'Tool Box' tab, and there was a stack of all the things you'd put on the clipboard while editing.  I can't seem to figure out where it went too...hopefully not the bit bucket... TIA, Howard Hoffman Howard, The clipboard ring still exists, though it's no longer exposed through the toolbox.  In order to access it, hit Ctrl+Shift+V multiple times and it will cycle through the clipboard ring. Hope that helps! Anson Horton [ansonh@microsoft.com] Visual C# IDE PM ...Show All

• .NET Development Updating Access from Data Table - slightly confused

  I'm using vb2005 to create a front end to an access database. Being new to this I'm slightly confused over what the wizards will create automatically as opposed to what I have to code. I've used the table adapter configuration wizard and specified that I want it to create methods to update a table called 'Categories' in the database. This is a simple table with a text field for the category name and an autonumber field (CategoryID) as the primary key. Now, I've read the supplied help info and a few newgroup posts about how to update a table row containing an autonumber field by using the RowUpdated event of the adapter class.
