• .NET Development Internals of remote object creation

  Hi all, When you have a code segment like the following: ChannelServices.RegisterChannel(new TcpClientChannel()); RemotingConfiguration.RegisterWellKnownClientType(typeof(TransactionMaintenance), "tcp://localhost:1235/TransactionMaintenance"); this.transactionMaintenance = new TransactionMaintenance(); I wasn't able to find a link between the type registration and the object instantiation. If you inspect the IL for this code the object instantiation is done with a newobj opcode just as would have been done for a local object. How does the CLR know that it should instantiate a remote class instead of a local one Thanks in advance. Alfred Gar ...Show All

• SQL Server New SQL Server 2000 worm?

  Hi all. My SQL Server 2000 SP4 installation running on Windows 2003 server (SP1, all patches current) has been infected TWICE by something that Sophos can't detect. The symptoms are that an account called SQLsys is created on the machine and is made an administrator. A service called "ApptoService spoolsrv" is created. An executable called syss.exe is also created in a few places. After infection the machine immediately starts attacking other computers on the network. I had Windows Firewall running, with ports open for SQL server and Remote Desktop. I ran the MBSA, it didn't find anything open. I even ran the beta MS web tool for ...Show All

  I hope this is an easy question. I've a lot of unresolved sybmol error messages while linking my executable. I think that I probably forgot to add the additional libraries that I wish to link against.

Take a look at http://msdn2.microsoft.com/en-US/library/ba1z7822(VS.80).aspx for adding your libraries to the linker command. Hope this helps! Thanks, Ayman Shoukry VC++ Team ...Show All

• SQL Server Replacing sqlserver 2000 with sqlserver 2005 express

  I have an app that uses a sqlserver 2000 jdbc driver to connect to a sqlserver 2000. Is it possible to do a direct replacement of sqlserver 2000 with sqlserver 2005 express just by reconfiguring the app to point to the express The app would still be using the sqlserver 2000 jdbc driver to try and make the connection. If that is a possibility, what can be some differences in the configuration Previously with 2000 the config information I entered is: server name: "machinename"( or ip). I've also tried "machiname/SQLEXPRESS" DB name: name of db instance port: 1433(default) user and pass. My attempts so ...Show All

• Visual Studio Team System Code coverage / signed assemblies / unit tests fail

  Hi, I'm using VS 2005 RC1 and having problems with a unit testing/code coverage/signed assembly combo meal. I have unit tests that succeed against the assemblies without code coverage turned on.

• Visual Basic Pointers In VB?

  Is there anyway of converting the following C# code to VB Vector3* myVector3 = (Vector3*)&someMatrix.M31; Thanks If Vector3 is a struct and M31 is a float, then both are value types and you need "real" pointers (using * and &), which you can only do in C# and C++. VB does not support this. Your best bet is to write these parts in C# and then reference the C# assembly from the rest of your VB class library. ...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.
