• .NET Development WeakReference and TrackResurrection

  I would like to understand the difference between short and long WeakReference in .Net, and in particular how they are respectively intended to be used. I think a have a clear view of the short weak reference behavior and purpose. But my understanding of the long weak reference is limited. In particular, I do not really understand the resurrection metaphor, is-it possible to re-root the reference from within the finalizer Thanks in advance, Joannes There is no safe pattern that I know of, and due to the non-deterministic, unordered finalization of objects, I doubt it's possible to design one (every obje ...Show All

• Windows Forms bind to indexer

  Hi, It's possible to bind to a indexer (ex: a["name"]) in VS 2005 beta2 (specially for datagridview) OK - you may be looking for something like the sample below - it takes virtual properties from a "model" and presents them to the DataGridView as "real" properties.  It involves implementing ICustomTypeDescriptor - and although a bit complex this is extremely powerful (and how ADO.NET does a similar thing).  It should be fairly simple to adapt your Entity type to this: class EntitySample : ICustomTypeDescriptor {     Dictionary< string , object >  ...Show All

• Microsoft ISV Community Center Forums Defining a range according to the number of responses

  Dear all, I'm a new user of Visual Basic (version 6.3) and need to write a Macro for use in Excel. I need the Macro to calculate Rank values for an unpredictable number of scores. The number of scores that need to be Ranked will vary and I don't know how to incorporate this variation into the Visual Basic Macro. In my current spreadsheet there are 11 scores (Sorted in descending order) in column DS (cells DS2:DS12). The Visual Basic code is as follows (DT is the column where the Rank values will be sorted): Range("DT2").Select ActiveCell.FormulaR1C1 = "=RANK(RC[-1],C[-1],1)" Selection.AutoFill Destin ...Show All

• Visual Studio Express Editions VB Express with Office

  I just downloaded VB Express (thanks, Microsoft! ), and was wondering if it has the capability to interface with Office, as its big brother, VB .net, does.  My primary development language is VBA (mostly Excel and Word, some Access), but can see the flexibility in using stand-alone Windows apps with Office.  Is MS planning on offering VB Tools for Office, as big VB has   Try http://uk.builder.com/programming/windows/0,39026618,39283157,00.htm .

• Game Technologies: DirectX, XNA, XACT, etc. DX sdk 2005 october and vs2005

  As far as I can tell, the october version of the sdk should have support for net 2.0 and as such is updated for vs2005. The question is then why the installer can still not recognize that you have vs2005 installed and thus let you add the visual studio integration. It seems that you need to install BOTH vs2003 and vs2005 to have this integration. If you do this then you (that means I) experience that the shader debugger when run from debug/directx/run with dx debug,  does compile the project but does not start it. When running the application without debug and attaching the shader debugger, it complains about missing debug info. Why thi ...Show All

• Visual C# Excluding files from release mode?

  I have a couple classes (one per file) that are derived from abstract base classes that are only there to give me easy unit test access to some math functions in the base class. Is there a way I can exclude them from a release build since they aren't used except by the unit test project You can try surrounding your class file between #if DEBUG and #endif pre-processor statements. The DEBUG symbol isn't defined in Release mode, so effectively your class won't be included in Release mode. ...Show All
