• SQL Server What's the performance difference between WITH and a subquery?

  Hello Everyone, Does anyone know if there is a performance difference between the new WITH clause t-sql and the subquery On a basic functionality level, they seem to perform the same function but I was wondering if there are any performance difference between the 2 Thanks, Joseph I'm guessing that you mean 'common table expression (CTE)' ..

• Visual Studio 2008 (Pre-release) Expressions Invoking Other Expressions

  Hi all, I've been playing with the LINQ May CTP. I'm particularly interested in the expression tree stuff. It looks really great, but there is one aspect that is not quite working the way I had hoped. I'm posting to see if I'm missing something or if this is likely to be addressed in the future. Ok, so I can write a lambda expression like this: Func<int, int> add5 = x => x + 5; And then I can write another lambda expression that uses that one: Func<int, int> add5AndDouble = x => add5(x) * 2; This all works great. Now let's say that instead of working with delegates I want to work with expression trees. I'd like to be able to do the exact same thing: Expression<Func<int, int>> add5Tree = x ...Show All

• Windows Forms Cannot get custom action to build in my setup project

  Uggh, This seems like it should be so simple. I've created a Win32 dll, with an exported function as follows: UINT __stdcall Uninstall ( MSIHANDLE hModule ) { /* display's a msg box 4 now */ } Then I created a .def file for the project that defines the export as follows: LIBRARY "UninstallCustomActions.dll" EXPORTS Uninstall This builds fine, and I can use dll explorer tools to examine the exported functions, and mine is there and looking good. However, now I add this project output (I tried adding the dll directly as well) to the installation project, create a custom action for uninstall and select this dll. I set the EntryPoint property to Uninstall, and make sure the InstallerClass property ...Show All

  When trying to publish the results from a webtest to source control I get the message of "Attempted to perform an unauthorized operation".

• Visual C# Trying to determine Class by a string value

  I'm having a DUH moment here and hopefully someone can answer it before I'm bald... I have a string that contains the name of the class and I want to create a new instance of the class that's referrred to. I have: string classToUse = "StartMeUp"; I have a class called StartMeUp that does some function... Of course, I want to create a statement similiar to: StartMeUp smu = new StartMeUp(); However, I've forgotten how to use the string to get to an object name... any helpers out there You're correct... when I tried it, I couldn't come up with logic to do that step, but due to having a short deadline for the prototype, I implemented a switch to determine which class to run, although I'm going to try this ...Show All

• Software Development for Windows Vista How to install additional filters into the XPSDrv Filter Pipeline.

  There are a number of references in the documentation that suggest it should be possible to add additional filters, beyond those supplied by the printer driver's manufacturer, to the pipeline. Specifically, the latest Windows Driver Kit (build 5744) says this (on the topic of Filter Pipeline Configuration File): Vendor driver functionality should be primarily in R1 (print processing) and R3 (rendering). You should limit Administrator modification to R0, R2, and RE. The separate regions allow filters from several pipeline configuration files to be combined together in a deterministic way. A separate pipeline configuration can, for example, specify a watermark and an accounting filter that are to be inserted into every dri ...Show All

• SQL Server Addicted to Stored Procedures: A time series problem. Is it possible?

  It's been about two weeks since I first began using SQL Stored procedures and now I am thinking already about changing many of my plans and doing those operations in them. There is a problem I want to address and see if it is possible to accomplish it in SQL Server instead of the client C# code. I have a time series. In simplified presentation it is a table of two columns. The first one is float, the second is DateTime. There might be quite a few rows in the table: A1 ... DT1 A2 ... DT2 ................ An.... DTn What I need to do is to find patters among A1,A2,....An elements. They vary in magnitude in a rather random order. They constitute what some would call a Markov chain. I demonstrate what I want in a couple of real life example ...Show All

• Visual Studio Shared Memory Provider: No process is on the other end of the pipe.

  I'm unable to install SQL Express 2005 on a windows 2003 server.  I have installed it on several 2003 servers, but for some reason, the one I need it on will not install.  I have tried the manual install, and the command line install.  Both give the same error.  Setup gets to the point where it is configuring the server, and then I get the following error. SQL Server Setup could not connect to the database service for server configuration. The error was: [Microsoft][SQL Native Client]Shared Memory Provider: No process is on the other end of the pipe. At this point in time, I can go to services and see that the SQL Service is running, so it has started.  However, upon failure, when I hit cancel, the process ro ...Show All

• Visual Studio Team System The good, the bad, the ugly

  Good: First let me tell you this has already been very useful to me. When I set up our transactional replication in SQL 2005 the nonclustered indexes weren't replicating properly (even though I set the option through the GUI). Obviously the replicas were slow and since they were being used, I was unable to try to recreate the replication schema. Instead I whipped up Database Pro and did a schema compare on our publisher and subscribers and scripted out the non-clustered index. It worked perfectly and I was able to apply the scripts on our replicas. Thanks. Bad: However we are creating a new database (actually 4 different databases) in SQL 2005 using schemas, CLR, and Service Broker. I simply imported the entire database schema fro ...Show All

• Visual Basic vb.net vs vb6 pros and cons help

Now, we develop a range of office plugins for a client, and they currently use vb6, they also do some other projects with vb6. I want them to change to vb.net They have asked me for a list of Pros for switching, and also some Cons. The pros i have are: .Net is future proofed, VB6 will not be supported by Microsoft for much longer One standard platform to run on (.Net) removing problems of windows versions and missing dlls  full OOP support and a generic Api for office application development.
