• Visual Studio 2008 (Pre-release) ObjectContext - pluggable/overridable for caches, etc?

  In the Overview document, Object Services has some listed features including: change tracking and entity loading. My guess is that these are handled by (or via) System.Data.Objects.ObjectContext. Will this class be 'swappable' or otherwise allow extension by allowing pieces of implementation to be plugged in perhaps by implementing certain interfaces I am thinking about situations where you might want to handle change tracking differently or load entities from another unsupported source or plugin a high-level cache. Similarly, extensibility for update processing Cheers, -Matthew Hobbs About extensibility of the framework... i have a very common problem in my domain, It is, objects versions. I w ...Show All

• Software Development for Windows Vista Transaction not committing?

  I've missed something somewhere. :) If I drop a Code activity into a TransactionScopeActivity, and then if I call a SQL Server stored procedure that updates a row in a table in the database, merely closing the connection in the TransactionScopeActivity should commit the data (assuming no other error). But it's not, at least in my case. I've set the IsolationLevel to all manner of things: Serializable, ReadCommitted, ReadUncommitted...nothing seems to commit the data. The stored procedure checks that it's in a transaction and errors if not, so I know it's within a transaction. It returns the modified column value as an out parameter, and the value is good. But the row/column never get committed in the database. I'm totally convinced I ...Show All

• Visual C# VS 2005 IDE Bugs, problems and suggestions

  Hello, I can't find a way to submit bugs or suggestions regarding VS. So here's a topic for that. Apparently bugs in the VS 2005 IDE: - the Document Outline window doesn't show XML files structure as it did in VS 2003 - when an item is selected in the Class View window (e.g. a namespace or a class), the item's properties are not displayed in the Properties window, as it was in VS 2003.

• Visual C++ COM newbie question

  when i use COM objects from C++ i need GUID and interfaces definitions.. i usually get them from an header. I noticed also that when i add a reference to a COM object (dll) in a C# project, the enviroment get directly all those informations about classes and interfaces. this suggest me that i could use COM objects even without headers. So my question is, it is possible to retrieve guids and interfaces definitions from a com object thanks to everyone in advice :) C# IDE does this by reading COM component type library. To to the same in C++ use #import directory with COM Dll name. It reads type library and generates wrapper C++ class which can be used by client code. ...Show All

• Windows Forms ToolTip Owner Draw

  I have created a ToolTip class and set the OwnerDraw property to true. I have hooked the Draw and Popup events and it is working ok. The content that I am rendering contains graphics and text. I'm just wondering why the only way to popup a ToolTip forces you to specify some text, for example: _calloutToolTip.SetToolTip( _mainPicture.Renderer, "dummy" ); All the overloads for Show also expect text. Is there anyway round this No real problem here, just a little bit backwards with the API. A Show() overload with no text would be a bit more intuitive. Maybe for the next version of the product will create a Component (SmartTag - like the Outlook notifier) to encapsulate a tool tip / contex ...Show All

• Internet Explorer Development IWebBrowser2:Navigate() Err under IE7

  Hi, This is an IE7 specific issue since it's been working fine so far under IE6.

• Visual Studio Express Editions Importing VC++ 6 Project

  I have an AppWizard generated project that was built in Visual C++ 6.0. I recently installed Visual C++ 2005 Express, and have not been able to compile it. It can't find any of the afx*.h files. I noticed that someone posted that MFC is not supported on VC++ 2005 Express. Is this true If so, is that only for the Express edition or is MFC support being dropped entirely If it is true that MFC is not supported, can VC++ 6 and VC++ 2005 co-exist on the same computer I'd like to use 2005 for any new projects but I still need to support the old ones. The differences between the various versions of Visual C++ 2005 are explained here . ...Show All

  Reading the FAQ, it did state you could utilize audio... But my question is can you target music through the Window's Media Connection Any thoughts I am assuming you mean on the 360, and I can't see any reasons why not, most 360 games allow background music to be played while in the game Although with the whole no ingame networking restriction it could also restrict using the Windows Media Connection, but if you can wait a couple of hours you will find out I'm sure ...Show All
