• Visual Studio 2008 (Pre-release) Using Network Load Balancing NLB with WCF - Failover to another cluster results in CommunicationException

  Hello, I'm trying to create a simple sample WCF service that is hosted in an NLB cluster on IIS. I have created the cluster successfully, and have a simple WCF client that prints out the name of the machine it is connected to when you click a button. If I goto the cluster node the client is connected to, and disable its LAN connection, then I can see the fail-over occuring: If I browse to a simple "Hello World" html file containing the machine name, I can see that the IE browser is successfully redirected to the other node. Unfortunately for my WCF client when I click the button to print the machine name, instead of getting the machine name of the 2nd node, I get a CommunicationException: The underlying connection was closed: A ...Show All

• SQL Server Pausing Log Shipping Plans

  We are doing an IP Restructuring on our DR site over the weekend due to some business and management requirements.I actually have 2 questions. I have implemented log shipping plans for our databases. Which means I will have to pause (disable) my log shipping plans while this is being done and resume (re-enable) after everything is comlete. Any insights on what else I need to do apart from these My second question is this. I am generating transaction log backups every 15 minutes and is averaging at 350MB (this much data every 15 minutes - not to mention that I've got around 40+ databases, all configured for log shipping just for this instance alone). My alert threshold is 45 minutes. My log shipping plan for one database starts failing pr ...Show All

• Visual C# HELP!!! Unresponsive keys in IDE! All of the special keys, including ENTER, DELETE, Arrows, etc! Very weird!!!

  I'm getting nuts with this! Suddenly, 2 days ago, my Visual Studio IDE stop responding to any control key (Enter, Insert, Delete, the Arrows, Home, End, Page Up, Page Down, all of them!), but still types in any other alphanumeric key (including the numbers in the keypad with NumLock on) Obviously this makes editing impossible, and is making me go out of my mind! This happens with any file type, in any language, even txt files, but only in Visual Studio’s IDE (even god old Notepad behaves perfectly normal and recognizes all keys) I’ve already done everything I could think of, including uninstalling and reinstalling Visual Studio several times (in one of them I “hunted”, and destro ...Show All

• Windows Forms clickonce deployment downloads frozen

  I have a windows forms application developed in VS.2005 in VB.NET 2.0 I've published the application to the my local IIS webserver for deployment. Within the local network, the application will download and install without any problems. But when trying to install the application at another office over the internet, the download seems to stop and hang when it gets to approximately 40-50 % completion. No error is displayed to the user, the download window remains open but the progress never changes once it stops. The only way to close the download window is to end the process via task manager. This happens with every attempt to install the application remotely. There are no other issues with network communication to/from the webserver ...Show All

• SQL Server Pivot Select

  Hi, I'm able to get Pivot to work but I'm having trouble limiting the record set. I want it to select only records from this FiscalYear.

• Visual C# when to use "static"

  When creating business applications that have you know 3 layer design as far as Data Access, Logic, Presentation.....Why would you want to use static methods in your logic and data access layers...what are some benfits of having static methods something like that, as simple as that may sound, remember there is memory and processor overhead involved in creating an instance of the the "objectname" that are not needed when executing the returnstr() function, thus it provides a proformance advantage to not have to create the object just to use the functionality that it exposes. ...Show All

• SQL Server Time Dimension Browsing Very Slow - ProClarity

  Hello, I have a problem when browsing the time dimension (when cube cells have values) I have a standard time dimension with the following levels Year-Quarter-Month-Day. My cube has values for the years 2003 .... until 2006. 2002 Does not have values. When I browse the time dimension for 2002 (the year where cube has no values), I have no problem..but when I browse the dimension for values in the other years.... I wait until 1 minut to make a drill down in the dimension Pane (whitout executing the query).
