• .NET Development Safely pass data from a socket's BeginReceive method?

  Hey there! I'm writing a class called "Connection" that creates a telnet connection to a server, and I'm using a socket to handle the connection. I use BeginReceive to asynchronously receive data, and an event to pass the received data to anything handling it. Here's the sub that handles data receiving: Private Sub OnReceiveData(ByVal ar As IAsyncResult) Dim s As Socket = DirectCast(ar.AsyncState, Socket) Dim ReceivedBytes As Integer = s.EndReceive(ar) If ReceivedBytes > 0 Then RaiseEvent ReceivedData(Me, ASCII.GetString(Buffer, 0, ReceivedBytes)) Sock.BeginReceive(Buffer, 0, Buffer.Length - 1, SocketFlags.None, New AsyncCallback(AddressOf OnReceiveData), s) Else Disconnect() End If End Sub Now, when I mad ...Show All

• SQL Server Service problems after SP1 upgrade

  We have an instance of SQL 2005 enterprise that was upgraded to SP1 over the past weekend. This instance has been very stable and the server hardly ever has any issues. After upgrading to SP1 a couple times a day SQL service has been terminating unexpectedly. The following events are being logged - Application Log: Event ID 17311 SQL Server is terminating because of fatal exception c0000005. This error may be caused by an unhandled Win32 or C++ exception, or by an access violation encountered during exception handling. Check the SQL error log for any related stack dumps or messages. This exception forces SQL Server to shutdown. To recover from this error, restart the server (unless SQLAgent is configured to auto restart). SQL Ev ...Show All

• Visual Basic UserDomainName - Domain or Workgroup?

  Hi all, I've used System . Environment . UserDomainName to find out what domain/workgroup the user is on, but how do I know if its actually a domain or workgroup that they've logged onto. I want to be able to do stuff if they're not logged into a domain. Thanks in advance... Scott There may be a more official way but I found this: http://www.devx.com/tips/Tip/26562 type=kbArticle&trk=MSCP Basically you attempt to enumerate the DC name for the "domain" part of the user name, if it pops back with a name then you are in a domain, empty then workgroup. Not tried it and seems a bit untidy but may work. Had a bit of a play, do not have a domain ...Show All

• SQL Server Error 28092 when upgrading from Express to Workgroup Edition

  Hello, when I try to upgrade SQL Server 2005 using this command line: setup.exe /qb SKUUPGRADE=1 UPGRADE=SQL_Engine INSTANCENAME=Z1 SQLACCOUNT=NT-AUTORITAT\SYSTEM SECURITYMODE=SQL SAPWD=XXXXXX I get error 28092 (administrator rights needed). It seems like the upgrade tries to use Windows authentification although I've told it to use SQL Server authentification. Or did I miss a parameter in my command line If I do the upgrade manually it works without needing Windows authentification. This error means that the user who is running the setup is not sysadmin in the SQL instance. It makes sense this happens on Vista because of AUC the user is not recognize as NT administrator.

• Visual Studio Team System Hierarchical work items

  Hi all I played a little with the work items in VSTS and I wondering if it is possible to define hierarchical work items. This would be a feature that I need for shore. I saw that there is an "Add related work item" menu, but using this is not really giving me the hierarchical feeling that I need. Is there a way to define hierarchical work items Regards. George. We don't have inbuilt support for hierarchical work items in v1. We are currently working on providing this ability in next release. You could work around it by using a Parent field to WIT definition to build a hierarchy. If you really want the support you could build it using our linking extensibility but this will be quite a bit of ...Show All

• .NET Development type resolution ?

  My problem is the following ...   1. I want to write a plugin loader that loads a concrete plugin implementing IPlugin 2. I Plugin does something when its methods are called. Some methods take a parameter e.g. IPlugin.PerformWork(ISomeInterface RealImpl); assuming an implementation MyPlugin : IPlugin { /*SOMETHING HERE*/ PerformWork(ISomeInterface RealImpl) { Console.WriteLine("PLUGIN PERFORM WORK"); SayHelloWorld(); SaySomething(); } 3. How ISomeInterface looks like is defined in another library e.g. interface ISomeInterface { void SayHelloWorld(); void SaySomething(); } now I load the plugin from within my plugin loader and execute PerformWork(..) on the plugin.

• Visual Studio Visual Studio 2003 help very slow

  I have Visual Studio 2003 with the MSDN library installed locally. When I search in the help the topics are found instantly, but when I click on the topic the help goes off to the web and downloads the help topic. This would be all well and good but it sometimes takes up to 5 minutes to do this during which time Visual Studio and all other running programs are unusable. I have ensured that ALL the help is installed locally, but I cannot find any options to specify 'Load help locally', not from the web! Has anybody else experienced the same problem More importantly does anybody know a solution! Thanks in advance. Thanks for the reply... I tried that this morning, initially it looked to be quicker but a lit ...Show All

• Visual C++ FindWindow usage

  Hi all. I've narrowed my searches of the FindWindow function down and found out a lot what i was doing wrong. However i still have a problem, the function compiles and works fine, because i used if/else statements to make sure it was working up until the end. Im trying to get the address bar of IE but i keep failing. I remembered Spy++ 6.0 and used it to find out the class that the address bar is in.
