Visual Studio 2008 (Pre-release) Bug Fixes
Hi, Being a developer I know that writing software is a tedious business. I would just like to know how much time is spent by the WPF team going through bugs at the official bug logging site ( connect.microsoft.com) The reason why I am asking is because I logged a few bugs that are really critical for the application we are developing, and I would like a "timeline" as how long the whole process would take before the changes is added in a next CTP (which already to long to wait) or maybe a patch Thank you very much, Jaco Hi, Ok no problem. 1. I always add legit Text and/or XAML content, otherwise the it would not display. The reason I am doing it this way is because the RichT ...Show All

Gadgets Can someone test my gadget please?
I posted my gadget a couple weeks ago and it has gotten a good number of downloads (~1500 atm) but mostly negative response. I suspect the problem is that I developed and tested this gadget on Vista RTM, but the Gallery only lets you choose "RC1" as the newest compatibility level (stupid ). I have not had any problems loading into the Sidebar on any RTM machine. What would really help me is to get a few people try to load it up and make sure it is working properly under a variety of environments (RC1, RC2, Beta, RTM, whatever), so I can figure out what the issue is that people are having. You won't be able to test the full functionality of the gadget because it requires you to have a particular type of webcam to stream video. ...Show All

Visual Studio Express Editions The Newbie Guide to Installation of Visual Studio 2005 Express Edition (Dont do the mistake I did!).
Just 2 days back I had downloaded Visual C# 2005 Express Edition from the link below http://msdn.microsoft.com/vstudio/express/visualcsharp/download/ I was in a hurry to download it and straight away clicked on the DOWNLOAD NOW link on the Right Panel. Now what that does is it installs an Installer onto your system,around 3 MB and then you have to Connect to the net and then download the entire package which inturn runs the setup. So today I wanted to take the back-up of those files,only to find that there are no Setup Files located in my Directory There was a Directory Called Visual Studio Express Edition 2005-ENU.I tried to run the setup directly..but it hanged. So what if your computer crashes or you need to b ...Show All
SQL Server Remote Source and Destination Performance
Given the following scenario, what kind of performance should be expected in transferring about half a million rows We are seeing about a 9 minute execution time. Is this reasonable for about 460,000 records moving from source to target, with 3 inner joins from the source Source: Server A.OLTPDB Target: ServerA.DataMartDB Server A is running SQL Server 2000. SSIS is running on a different machine, Server B. The reason for this is that we are distributing the SSIS package for use with a BI product built on SSAS 2005 and the requirements are such that the client could very well have the source OLTP database on a different physical machine than the data mart. My understanding is therefore that: 1. SSIS will do all of the hea ...Show All
Visual C# advice needed on using lock()
currently i'm coding class that involves buffered file writing. scenario is pretty usual: you instantiate class, set properties, when needed call class methods. my class internally processes passed to methods string values and stores them in MemoryStream buffer. if buffer exceeds the specified value FlushBuffer() method is called, buffer is written to file. what i want to do is to run FlushBuffer() method in separate thread to not 'freeze' or slow-down operations that are running in the class caller thread since file io is relatively slow process. but this involves problems. if thread with FlushBuffer() method is running while the user calls class method that should process and store some string value in the buffer then some prev ...Show All
Visual Studio Team System The application for project is not installed (project types .rptproj and .dwproj)
It used to work, but then... Visual Studio 2005 was hummin' and I had a number of BI projects in both Report Services and Analysis Services. I wanted to add source control and decided to install the Team Suite and I did something wrong. I just don't know what it was. In the end, I deinstalled every Visual Studio 2005 (including, of course,the Team stuff)and SQL Server 2005 application, and reinstalled old faithful Visual Studio 2005, but nothing has worked. I'm missing the Business Intelligence project templates completely and I'm guessing that if I had them, I wouldn't get either of the following 2 messages when I try to open existing projects: "The project application for 'c:\...\SOS.dwproj' is not installed. Make sure the ...Show All

Hi dear all, does anybody know the maximum length for an mdx formula for a calculated member in SSAS Kind regards Frederikm There is a syntax error in your formula somewhere, and the error message should give you an idea about location of this error.
