• Visual Studio 2008 (Pre-release) DLinq Designer / SQLMetal in Orcas January CTP

  Hello, Just looking at using Linq to SQL (Dlinq) in my final year disseration as it has some really interesting points for me to talk about. I was trying to create a database file (sorry, not sure what the true terminology is) using either the DLinq designer or SQLMetal but I can't seem to find it in the CTP. Will I have to wait until the Feb CTP or use the old May CTP to access this Or am I just missing something Thanks for your time. Ben It looks like we take a few steps back for every step forward. Its understandable for a CTP, but it cost me about $60 to download. I wish I has known before hand. Regards Craig ...Show All

• Visual C# Any way to mix C++ templates and C#?

  I've been trying to write a small library that depends on C++ templates (C# generics are just too restrictive for my purposes), but I'd like to be able to access and use the final library from C#. I haven't been able to dig up much information about this, but my observations so far are that: 1: If I just define a class template in a managed C++ assembly, it's inaccessible from another assembly (This makes perfect sense given how and when C++ templates are instantiated. I'm actually surprised this is possible between two managed C++ assemblies) 2: If I specialize the class template, the resulting type is not accessible from a C# assembly either. That is, I do something like this in my C++ assembly: template <typename T ...Show All

• Visual C# Windows Service -- do I need to reinstall my service every time I change something?

  Question changing code in my Windows Service. Let's say I have a Windows service, MyService, which uses dll1 and dll2. When I build I see MyService.exe and dll1.dll and dll2.dll. Let's say I have changes in dll1 and dll2 but not in MyService. Assuming that I stop the service first, is it sufficient to just copy in the new dlls and restart the service, or do I have to actually do a re-install of the service I can think of no reason why I should have to reinstall (isn't it just the exe that gets installed ), and when I tried just copying over the modified dll it worked, but I thought I'd ask the question to be sure having been bitten by COM in a similar situation a couple of years ago.

• Windows Forms TabOrder for multiple groupboxes and other container controls

  vb2005 i have a form which has multiple groupboxes, tablelayoutpanels, and other container controls. i would like to set up a TabOrder which not only stores how to tab within each container control, but also stores on which order do i want to tab from one control to the next. for example, if i have 2 groupboxes on top, and 2 groupboxes on bottom, how do i set up a tab order that goes Up-Down within each groupbox, and Left-Right from container to container thanks! I believe this would just be a simple matter of setting your tab order in each control within each group. So in group box one (top left) each control you want tabbed into would be numbered 0 to m. In group box two (top right) each control you wa ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. What does creators club include right now?

  I'm a little puzzled about what the creators club actually includes, I've checked the FAQs and can't really find an answer. I have however managed to find the following: "The XNA Creators Club is available on Xbox LiveR Marketplace for $49 (U.S.) for a four-month subscription, or $99 (U.S.) for an annual subscription. Both subscriptions provide aspiring game developers with access to thousands of game assets from Microsoft and key partners such as Turbo Squid Inc., as well as white papers, specialized starter kits, samples and technical product support to help turn Your World, Your Game into a reality."

• SQL Server Formatting dates on a chart when sourced from SSAS2k5

  I am creating a few charts in SSRS that are sourced from a cube in AS. On the x-axis is time, which is what I assume a date-like field in the cube. On the y-axis is the measure. My problem is that I cannot seem to get the dates to format on the chart - regardless of the format code I use, the dates appear in long format, like "Thursday, November 23 2006". Are the dates from SSAS just string values That's what I feared...thanks for the confirmation. Hopefully something to look forward to in Katmai [better integration between SSAS and SSRS, that is] ...Show All

• Visual C++ VS 2005 Compile C in C99 mode?

  Hi, Due to the fantastic debugger and Intellisense technology Visual studio provides, I am now attempting to write my C code in VS.Net 2005. I was able to compile C files, but the most annoying thing is that I cannot declare locals in "for" loops. Is there a way to configure the C compiler in VS.net 2005 to use C99 mode Thanks, Bahadir No, VC does not support C99 and probably won't for quite some time to come. There's support for a couple of C99 things (including for C++ mode), such as "long long", variadic macros, __restrict (which works like restrict), __FUNC* identifiers, __pragma (which is similar to _Pragma). Of course, you might want to think about using C++ mode -- after all ...Show All
