• 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 C# Regex, remove file extensions PLZ HELP !

  Hi ! Does anybody know how do I can remove all extensions of file with regex rules for example file: sdfkghsjhg3248-sdf_034--d3.org.filt.dat should be: sdfkghsjhg3248-sdf_034--d3 Right now I'm using quick fix: ^((\w*-*)+) But it is unlikely going to work with all possible filenames. PLZ HELP ! Hey there, I have looked into your problem and there is actually no way to really get just hte file name without the extension. All you can do is either remove everything and including the last dot in the filename or just take the eveything before the first dot in the filename ( which would be [\w-]+) Reason being is that filenames alone may contain dots, which is possible i can call my file my ...Show All

• Visual Studio 2008 (Pre-release) Using web services with xbap application

  I have created an wpf browser application that relies on calling a web service. However, whenever I call the web service, I recieve a "System.Net.WebPermissions" error message. The web service is located on a different server. How do I get this to work Thank you for the help. Steve I'm struggling with this too. I've created an xbap application, and an asmx web service, but I get the System.Net.WebPermission exception every time. Both the web service and the xbap are installed on the same IIS, different virtual directories (I'm not sure that it's possible to put them in the same directory ). Has anyone ever got an xbap application to connect to a database Or even got this alleged web s ...Show All

• Visual Basic Tough one, Share a Socket?

  Hello All, I have an off the shelf Windows app that is capable of calling a dll. Actually it calls a C++ wrapper which calls my VB.NET dll ( a VB.NET function ) and all is working fine. The VB.NET dll is designed to open a socket to a server and send messages using System.Net.Sockets. The VB.NET dll also starts a timer to send regular messages to the server in order to keep the socket open and displays a simple UI to handle additional messages that the user might want to send. All this is working fine...but here comes the problem. When the Windows app wants to send more messages it calls the dll that has previously created the UI and opened the socket that is now sending regular messages. That is to say the socket is already open an ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. MRT's on the xbox 360?

  With a chip dedicated to the framebuffer is it still possible to do MRT's on the 360 My initial tests suggest this is not the case but if anyone knows for sure I would appreciate it. We don't support MRT on Xbox in the current version of XNA. The underlying hardware does support MRT, but it needs to be handled in a very particular way because multiple targets tend not to fit into the 10 megabytes of EDRAM, so you have to render the scene in pieces and then stitch them together at the end of the rendering. We didn't have time to get that working in a clean and reliable way for XNA, so we decided not to expose this at all. ...Show All

  Does anyone have tried F# http://research.microsoft.com/ fsharp / fsharp .aspx If so, do you have any concerns/comments/regrets about it I've tried a little bit, but didn't use as much as it can be use, so I didn't see a real big difference with C# performance, but maybe I will use it much more in the future(Since I'm doing a optimization algorithm project at school). ...Show All

• SQL Server Create Table with variable name

  This should be simple, but... I want to create a table in a stored proc using a variable name instead of something hard coded. I was hoping to do something like.... CREATE PROCEDURE foo -- Add the parameters for the stored procedure here @TableName char = null AS BEGIN SET NOCOUNT ON ; CREATE TABLE @TableName ( [HRMONTH] [int] NULL, [HRYEAR] [int] NULL ) ON [PRIMARY] But no combination of names '@'s , etc, allows me to use a variable name that I passed into the procedure. What am I missing I will either receive a syntax error or the procedure will create a table called TableName rather than whatever TableName really stands for... Thanks, Tom ...Show All

• SQL Server SqlTransactions in a Multi-Threaded Environment

  I am currently working on a project in which I am using SqlTransaction objects with their IsolationLevel set to Serializable. I am wondering what would be the effect if multiple threads were to call this code at the same time Would the second transaction (created by the second thread on the same connection), for example, be queued until the first one (created by the first thread on the same connection) finishes Or would an exception be thrown for the second transaction In case an exception is thrown, would using the synchronization (locks) around critical sections solve the issue I guess it is easier to understand the scope of transactions in terms of multiple users, but it is confusing (for me) when I start thinking in terms of multip ...Show All
