• Visual Studio 2008 (Pre-release) .ForEach on Dlinq objects and Linq CTPs

  In future version of LINQ will I be able to do a .ForEach directly on the Dlinq objects For example: var batches = from b in this.m_Database.Batches where b.EndTime == null select b; batches.ForEach(b => b.EndTime = DateTime.Now); Also will there be any other CTPs of Linq for Visual Studio 2005, or will I have to download the entire Orcas CTP if I want to use the newest features Thanks. Also will we be able to .ForEach on a query For example: List<string> test = new List<string>(); test.Where(s => s.Contains("LINQ")).Select(s => s).ForEach(s => s.ToLower()); ...Show All

• Visual C# BITS AddFileSet Function

  I am working with BITSInterop.cs from Microsoft and I am having problems getting this function to work properly. I have changed _BG_FILE_INFO to be an array in both IBackgroundCopyJob and IBackgroundCopyJob2 (AddFileSet(uint cFileCount, ref _BG_FILE_INFO[] pFileSet);). For testing purposes I am using this: _BG_FILE_INFO FileInfoTest; FileInfoTest.RemoteName = " http://STLSMSAPP29/SMS_DP_softlib$/9753/Package.Binary "; FileInfoTest.LocalName = "C:\\winnt\\options\\Software\\MIC\\9753\\Package.Binary"; _BG_FILE_INFO[] strctArrFileInfo = { FileInfoTest }; uint intCount = 1; bckGrndCpyJob2.AddFile(" http://STLSMSAPP29/SMS_DP_softlib$/9753/Package.Binary ", "C:\\winnt\\options\\Software\\MIC\\97 ...Show All

• SQL Server SELECT DISTINCT problem

  I am trying this query which return 247rows: select * from event_log where event_id like '%accounts enabled%' and this query which returns 242rows: select distinct description from event_log where event_id like '%accounts enabled%' but I want to combine both together, which means I want to select all columns in the table but it should have a unique description field.. i tried: select distinct description, event_log.* from event_log where event_id like '%accounts enabled%' but it returns 247rows..

• Visual Studio 2008 (Pre-release) Nested/Inner Classes and the x:Type Markup Extension

  I posted this on the Usnet discussion, but there seems to be more action here, so reposting... I want to use an TargetType="{x:Type Yadda.Stuff}" where Yadda is a class and Stuff is an inner class of Yadda. Is this possible in Xaml I'd rather not have the namespace polluted with a wrapper class that I'm using to populate a TreeView (as I can't modify the data class itself). Any help is appreciated. Sorry, you cannot refer to nested types in XAML via x:Type or anyother type reference. If you don't want to do the "pollution", you could build a new markupExtension.  Like this (read to end before doing...): using System; using System.Windows.Markup; namespace Microsoft.Sam ...Show All

• Visual Basic Best way to store ip information of users

  I am writing this in VB 2005     Hello, I hope this belongs in here for it seemed to fit.  I am making an application that requires me to get the IP, and data so other users can user operations such as file transfer, IM, and more.  I would like to get your opinions on the best way to store their information so the tool isn’t confused about who is on, who isn't and what their information is.  I have obtaining the information done (ex: use my own web script get the external IP).     The tool will have probably about 5 users on at the same time with maybe a total of 25 users that use it.   With my two methods, I have a server with 100GB of bandwidth and many mysql-d ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Humorous but somewhat serious question about XNA

  Microsoft has claimed the Nintendo Wii as a "kids toy;" however, if XNA can produce graphics and push performance up to what the Wii is capable of handling (games like Half-Life, Sims 2 from most XNA performance claims), does that mean that XNA is a kids toy too redshock wrote: Microsoft has claimed the Nintendo Wii as a "kids toy;" Can you link to this quote Saying "Microsoft has claimed" is a pretty broad brush, and one that I take exception to. The Wii has merits as a gaming device, but isn't in the same category as the Xbox 360, but nobody here in the Xbox org (that I know of) claims it's a "kids toy". So...back it up with some proof (or edit your po ...Show All

• SQL Server Trouble with establishing server connection in SQL Server 2005

  I have been developing a web application using Visual Web Developer with SQL Server Express. The application includes databases (I’m having users create accounts to become members, and I use their profile information to customize some of the web pages to the particular member). I have purchased Visual Studio 2005 Pro, which comes with SQL Server 2005 Developer Edition. I installed both of these without uninstalling Visual Web Developer (I wanted to have my work transfer from VWD to VS Pro). When I open Visual Studio Pro, my web application is there, with the pages I have coded. But when I try to connect to the data base (e.g., by logging in as a member), I get this error message: An error has occurred while e ...Show All

• .NET Development Profiling and inlining

  Does anyone know of a profiler which will allow me to analyze the performance of jit'ed assemblies taking into account optimization like inlining I've tried the profiler built in to Visual Studio 2005 and I've tried IBM Rational's Quantify. Both of them seem to somehow cause the JIT not to do inlining (it probably doesn't do any optimizations). Consequently when I look over the results and try to identify bottlenecks (in a rather complex and long-running algorithm), the results from both tools are completely skewed by the fact that a few small accessor functions, which are called very frequently are not inlined. Right now I'm left with temporarily manually inlining these functions just for the sake of running the profiler, and th ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. "Use of unassigned local variable" error on Xbox360 but not Windows

  Anyone know why the compiler produces an error when the following code is compiled in an Xb0x360 project but not when it is compiled on a Windows project public void GetTileRect( int tileX, int tileY, out Rectangle tileRect) { Rectangle myRect; myRect.X = tileX * tileWidth; myRect.Y = tileY * tileHeight; myRect.Width = tileWidth; myRect.Height = tileHeight; tileRect = myRect; } I get a "Use of unassigned local variable 'myRect'" when assigning it to tileRect. It's not a big deal, I can get around it by simply using "myRect = new Rectangle()". I'm just wondering why it works in one case but not the other. The same compiler is used for ...Show All

• SQL Server Cannot open MSDB database from DTS Meta Data

  We are running SQL Server 2000, SP4. I recently noticed that my DTS packages were missing from the local server. Since I had saved them as Structure Storage Files, I imported them back into DTS Local Packages. That was yesterday. Today I opened the Meta Data browser to see what was in it. (We don't use Meta Data Services.) It displayed a message:"An error occurred while trying to access the database information. The msdb database could not be opened." These (restore of DTS pkgs and Meta Data error) may not be related, but I need to know why I am getting this error, because I am about to upgrade to SQL Server 2005 for Workgroups. 1. Does anyone know what causes this error message 2. Are local DTS packages stored in the MSDB ...Show All
