• .NET Development SerialPort SerialDataReceivedEventHandler

  Hi, I can't figure out how to get the event handler to work when data is received on the com port. I've looked around the forums here and I downloaded a console sample program that I tested on my computer and it works. But when I try and apply the same Idea to my C# windows form program I can't get the event to fire. Am I doing something wrong Some other post on the forum were talking about using different threads for the SerialDataReceivedEvent handler...  Thanks in advance for your help.

• Visual Studio Team System Team Project Creation Fails because of Sharepoint

  OK this one is killing me.  I have done the install about 3 times and keep getting the same error.  When I go to create a new team project, I step through the wizard and click finish.  The wizard then goes on to create the Reporting Services Part, the Source Control part, and when it gets to Share Point it fails on authentication.  Everything is in a domain and I have used service accounts as specified per the install. Here is the kicker, when I am local (terminal serviced into team foundation server) all goes well, but when I am on my workstation it fails and does not give me a whole lot to go on.  It barks about p ...Show All

• Windows Forms DataGrid Not Updating

  In my first attempt at using a DataGrid I created one that pulls data from a table in a Microsoft Access database. The data displays fine. I have an update command that should update the row. I have a row updated event handler that checks to see if the update threw any exceptions. It comes back with no exceptions yet my update is not happening. The fields are not read-only so I'm puzzled as to how it could indicate success yet nothing is happening. any ideas No and that is part of my confusion. In the sample code I've seen they make it look like the "updatecommand" line in the .aspx field is ...Show All

• Visual Studio 2008 (Pre-release) Why will LINQ fail ?

  Microsoft tries to helping object developers to close the gap between the relational world and the object world.And they call this " object modelling approach " Dlinq. Using " custom business entities " in enterprise programming with Dlinq might seem the best thing after " sliced bread " but it isn't. For my part I have written my Mappers and used commercial OR/M tools. They mostly provide the same thing. __Read the table from the database. ___Put that into a some HELPER thing.( DAO,DAL,ORM) ____Put that into your custom business object _____Read from your business object.(if u can :) ) I see NO REASON for this " Unnecessary Pull ...Show All

• Visual C# StringBuilder.Length adds null character not space.

  According to the Class Library Documentation, the StringBuilder.Length property will do the following... "...If the specified length is greater than the current length, the end of the string value of this instance is padded with spaces ...." When I try this it is padded with a null character "\0". So then I have to do a sb.Replace('\0', ' '). Is this correct and common knowledge What fundamental thing am I missing I just checked the implementation of StringBuilder.Length (using .NET Reflector ) in both .NET Framework 1.1 and 2.0. Both append null characters when the set length is greater than the current le ...Show All

• Visual Studio Team System Adding new project alerts?

  Hello, I'm a s/w program manager. I would like to have TFS send mail alerts to team members when I create a new task for them. I would also like to have TFS send a mail to me when they mark a task complete. None of the out of box alerts seem to fit this bill. Is this possible to set up, if so how Many thanks, Jon It might also be worth thinking about using the bissubscribe tool for another way of doing this by hooking into the WorkItemChangedEvent and then monitoring certain fields of the work item when it changes.

• Visual C# webBrowser1_CanGoBackChanged event doesn't fire!?
