• .NET Development UDP in VB.NET framework 2.0

  I am having trouble locating code examples for using the 2.0 UDPClient in a non-blocking fashion. Can anyone point me to examples in 2.0, or post some code to get me started I tried a few examples from msdn2 but the either dont work, don't work fully, and/or I dont understand what I am doing with Async :( What I need is for a winforms app to be able to send udp messages to one or more known ip address, and also receive udp messages at any time from one or more other remote clients. A class I could drop into my program would be ideal, but any examples would more than greatly appreciated. I have done a fair amount of tcp coding in 1.1, and even written full blown servers, but this is my first forray into udp and 2.0, and I'm a little lost ...Show All

• SQL Server How to see the query run on my server?

  Is there a way to view the exact queries sent to my server For example, suppose someone is running a report whose SQL query I would like to see, but it's not available to me for some reason. Would I be able to find a record of the incoming query Kiitos! Yes, it is possible, if you have the SQL Admin privelege, then you can use SQL Server Profiler tool which is meant to trace activities against a specific SQL Server instance. You have abilities to define filters and scope your data gathering to a subset of your interest. I specifically say that because you will surprised how bug your output can get depending on the activity. Some useful links - http://msdn2.microsoft.com/en-us/library/ms1 ...Show All

• Visual Studio 2008 (Pre-release) VS.NET dockable tab groups in WPF?

  Has anyone seen WPF classes which support all of the VS.NET 2005 dockable, expander, floating tab groups  I know there are partial classes that support some behavior in the November CTP, but, of course, I'm looking for something thats got it all ready to go.

• Visual Studio Team System Problem resolving merge conflict

  Merging from Main to Dev Get a conflict on file A Click on resolve conflict Dialog says building change summary Processor is shoots to 50% usage, fan kicks in and it never comes back. Let it run for 8 hours(over night) and it never came back. I have reduced the merge to just this one file and it will not return from resolve conflict. You can hit cancel and the dialog goes away but it never recovers from eating half of the processor. You basically have to kill VS. We've fixed this, thankfully.

• .NET Development static object garbage collection

  I have code that gets lists from that database and stores these lists in a static hashtable. this hashtable is in an abstract base class. My question is when is this hashtable GC'd, when the last object that inherits from the base goes out of scope never some other time When the application domain is destroyed, that would be the case, e.g. when the application ends. But you can also release the instance of the hashtable by getting rid of the reference to it, e.g. by setting the static variable to null or to a new instance. ...Show All

• Visual Studio Team System SQL Server collation is not set to one supported by Team Foundation Server.

  I get the error: "SQL Server collation is not set to one supported by Team Foundation Server." in the System Health Check. I've reinstalled the sql server three times (I've tried both the developer edition and the enterprise edition). My current collation is set to "Latin1_General_CI_AI" so this shouldn't be a problem!

I right-click the login in question and select Properties. I select the Status page. So I see I can deny, disable and lock out this login.
