• SQL Server Plug-in Algorithm in data mining using SQL Server 2005??

  Hi, actually i want to implement a c# component that can help third party data mining algorithm and i want managed plug-in algorithm (without wrapper),. is it possible to write whole application in c# as Analysis servisce is in c++ , can we implement it in c# thanks in advance ~Chinmay If you're trying the re-implement the COM interfaces in C#, it will be much harder than the managed C++ wrapper we've provided - you'll need to do your own research in that case. Testing the wrapper would be a combination of whitebox testing and a sample plug-in written using your custom wrapper methods (similar to the one we supply with our Managed Plug-in API Framework). ...Show All

• SQL Server Getting Report Server Running on Local Instance of SQL Express

  I have installed SQL 2005 Tools which installed Visual Studio 2005 including SQL Server Reporting Services Designers. I thought this would create a local instance of SQL Server 2005 but it did not.

How do I configure this local instance to be used for Report Server RS Configuration Manager Machine Name: "localmachinename" Instance Name: greyed out No report servers were found on the specified machine.

• Visual Studio Tools for Office Finding the current Table

  Hi, I have a Smart document with XML tags inside of a Word.Table. The rows repeat these XML tags so I end up with Word.XMLNodes. This is not a problem, but I would like to have different information load into my action pane when different XMLNodes are entered meaning that I want the user to enter information into the action pane, then be able to come back to the same node and populate the action pane with the previously entered information. I would also like to have different information for each XML node created by the user(as rows are added to the table). How do I get the row index of the entered node Thank you in advance for your help and support. Getting the row index of the current selection ...Show All

• Visual Basic Visual Studio 2005 Windows Service Starts but Timer does not execute unless in debug mode

  This is a very interesting one. I am able to deploy my VS 2005 Windows Service with a release configuration but when I do so, it does not begin to execute the timer until I am attached to the process. The timer is enabled and set to execute every 3 seconds but never does. I am using an account in which the same service works in VS 2003 so I do not think it is permissions. If anyone has any insight into this behavior I would appreciate it thanks... Hi All, I've a simple windows service written using VS 2005.

• Software Development for Windows Vista Video "pixelisation" using Video Mixing Renderer 9

  Hi, I'm working on a mpeg2 ts file video player relying on existing directshow decoder filters. This works great under XP SP2 with for example NVidia puredecoder, or any other mpeg2 decoders. Running my application under Vista RC2 Ultimate Edition, the video is pixelized as if the video was zoomed in. If I play the same file with Windows Media Player, video is perfect. This test has been done with default Microsoft MPEG2 decoder filter, and it seems to be the same with any other decoders. Does this have something to do with the Video Mixer Renderer 9 Did I miss something with it under Vista I also made a quick test with Video Mixer Renderer 7, unfortunately, it is the same result. If anyone can point me on the right way to ...Show All

• SQL Server SQL 2005 database will not attach in XP

• Visual Studio Team System Rename directory gets warning?

  I get a dialog popup saying. "Some of the files you are adding to your project are located outside of the project's binding root. These files cannot be source controlled unless they are moved. If the project's hierarchy on disk mimics the hierarchy in the source control database, you might be able to control these files by changing the project's bindings." Two conditions to note, I had built the code before so got a lot of warnings: <Directory> "Cannot be deleted because it is not empty" I also had the solution loaded when I did it, which probably wasn't a good idea. Is this expected, is there a way to avoid it Hi: From what I see in your ...Show All

• Windows Forms Sending email in vb.net 2005(using vb) not with smtp but the users outlook (mapi)??

  I have an application that I need to send mulitiple emails from. There are about 10 users who will have permission. However my IT Group has locked down the smtp server and will not allow "Applications" use the smtp method.
