• Visual Studio 2008 (Pre-release) LINQ install fails (May CTP)

  Hi, When starting the installer, I get the message: "Cannot find a valid Product to install LINQ with" and then tells me that I need a version of Visual Studio 2005 installed in the next dialog. I do have Visual Studio 2005 Professional (German) installed and I never had such problems with other previews that involved VS 2005 (e.g. Orcas). I believe that the problem is related to the german language version of VS 2005 since there was also a language problem in the last preview (you had to copy some files after installation). The last CTP however installed at least. Does anyone have a workarround for this I know that other languages then englisch are not officially supported, but if there is anything I can do to make i ...Show All

• SQL Server Export more than 65536 records to csv / excel

  Hi I have some reports which for some parametercombinations return more than 65536 rows. This obviously causes an error when I try to export them to CSV or excel, and the records are truncated at 65536 in the csv file, after the error. All these records are in one single table, and the reports are deployed in SQL Server 2005 reporting services. Can anyone suggest a way to make this work (splitting the data in separate worksheets or files) Thanks Shomik Setting pagebreaks in your table will cause a new sheet for every pagebreak when exported to Excel. You will need to determine a criteria for inserting the pagebreak (such as every 10,000 rows or something similar). ...Show All

• Visual Studio Express Editions Computed Column

  I am having trouble finding the correct sytax for formulae in creating computed columns. I would like to create three computed columns in my table in my database. The first is an average of the last 20 prices, the second is the average plus one standard deviation and the third is the average minus one standard deviation. I would appreciate any help. I have tried even simple formula but nothing seems to work, i keep getting error messages. Thanks for the tips. The tutorial was a great help in the beginning and I will probably add alot of it to my project. The Spreadsheet Gear program looks awesome, but expensive. I am not really code adverse, just trying to do things the most efficient way. This has been a great learning process...mor ...Show All

• Visual Studio 2008 (Pre-release) WCF Performance: ASP.NET Client

  I'm trying to compare performance of WCF services (recent release) with ASMX webservices in the scenario when service is called from ASPX page, under load (hundreds of concurrent users). Here is the client code in aspx.cs: MyServiceCleint proxy = new MyServiceClient(); proxy.MyTestMethod(); proxy.Close(); MyTestMethod() here doesn't really do anything, just a stub that returns an empty string; WCF security is disabled - so there should be no extra overhead. WCF service is hosted in IIS. It seems like WCF service performs much worse than similar ASMX service - WCF is more than hundred times slower ( !). I have tried different modes/settings such as ConcurrencyMode, InstanceContextMode and Throttling as described here: http:/ ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. A Few Questions

  I've been programming for a while, but I can't grasp a few basic concepts of game development, so I have a few questions (actually a lot of questions, but i'll only ask a few) I see a lot of documentation talking about 3D stuff, but I'm interested in 2D and it's hard for me to relate 3D tutorials to 2D. What exactly is the SpriteBatch class, and how should it be used Would I derive an "enemy" class from SpriteBatch I don't understand the way a "camera" works.. if you move a camera, is the actual camera moving or are all the sprites moving Do I have to move them manually I fully understand there is a help file, and I have looked at it and I will continue looking at it.. ...Show All

• Windows Search Technologies Search result appears in "Indexed Locations" but not in "Everywhere" on Vista

  My custom protocol handler is finally working to the point where I can search for keywords indexed from a custom store and get the appropriate results back. BUT, this only works if I search specifically in "Indexed Locations". If I go into the search textbox in the start menu and just type in a search term, it searches by default in a location called, "Everywhere". This location should be a superset of "Indexed Locations", but search results for items indexed via my protocol handler do not appear here. They only appear if I actually NARROW the search to look only in indexed locations. Can someone explain why this would be the case, and how I can fix my code so that my results appear when a user searches ...Show All

• Windows Forms Drawing parts of an Image

  Hi - quick question. I need to use DrawImage/DrawImageUnscaled to draw certain source areas from a certain Bitmap, using a Graphics object, many times. I've tried many variations of the call and they all are very slow... 30~50 iterations takes almost a second. There's nothing I can do about the size of my image file either, unforunately. Making it a small-size PNG doesn't help at all. Also, I really want to avoid using DirectX here for the reasons of simplicity, load-up speed, and also the fancy advanced features like gradient brushes, etc. that I really need. So, to my actual question - is there any other way to greatly improve my speed without using another technology than GDI+ Thanks in advance... P.S. I should add that I can't reall ...Show All

• SQL Server Using a parent-child dimension where you track and report as per the history

  Hi, At this point, I'm simply trying to see if what I'm trying to do is possible. If anyone has tried this before, I'd appreciate to know how they've done it. Say I have a single DSV with a single table such as the following: TABLE Members ( ChildID int, ParentID int, Period datetime ) which contains data like this: ChildID ParentID Period 1 4 2006-10-01 2 4 2006-10-01 3 4 2006-10-01 4 5 2006-10-01 5 6 2006-10-01 6 NULL 2006-10-01 1 5 2006-11-01 2 4 2006-11-01 3 4 2006-11-01 4 5 2006-11-01 5 6 2006-11-01 6 NULL 2006-11-01 In words: In 2006-10-01, 4 has three childs and is under 5 which is under 6.

• SQL Server Report Services Configuration Error

  Hello, I am a complete Newbie with SQL Server 2005. Can someone help with this problem or at least point me in the right directio for diagnosing it correctly. I'm learning the Standard SQL product on Windows XP Pro, and everything on my computer has the latest updates (from Windows Updates). I had previously installed SQL Express, but removed all products associated with that according to steps listed at Microsoft's site (pre-installation steps for SQL Server 2005 Standard, as they relate to the removal of SQLExpress). My problem is I can't run "Reporting Services Configuration". When I try to run it, the main window opens with "Report Server Installation Instance Selection" window, and immediately I get an ...Show All

• .NET Development Cross-Thread Events

  Is there any way of directly raising an event in another thread The way I implement such a task now is by using SynchronizationContext.Post to call a method in the other thread and then raise the event from there. If it is possible to directly raise an event in another thread I doubt that it would cut down on the overhead, but it would reduce the complexity and size of the code. Hi, I do it using the same technique as you, posting using the synchronization object. I have seen implementations where you build a proxy object that can expose methods to raise events. This proxy is visible in both threads (static if the sync is between two threads only or instanceable if there will be many objects). Therefor ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Setting project up to be cross platform

  Hello Any advice on what's the best practice for setting up your game to run on both PC and Xbox Even better if there could be an included example of this. I'd like to develop my game on the PC and only running the 360 version periodically. In the past I've set up seperate builds so I'd have a release\debug versions for PC, PS2 and Xbox1. I've seen posts mentioning creating one solution with two projects in and then adding the source to the other project as a link. I have my project like this but I find I'm having to add any new source files twice, once to the PC version and once to the 360 version. The same goes for any data I decide to add. This doesn't seem the best way of dealing with it so has anybody come acros ...Show All
