Game Technologies: DirectX, XNA, XACT, etc. frames per second benchmark for games
Hello all, I'm John, a newbie to real-world apllication development. My experience so far has been in the classroom working with C/C++, no DirectX knowledge yet. I would l ike to write a program that will allow users to benchmark games by analyzing frames per second (FPS). My main hurdle at this point is retrieving the FPS information from the games. I believe the answer lies in understanding DirectX programming. Here's a brief summary of what I want to do in my program: - allow the user to start/stop benchmark process. - while benchmark is running - gather d ...Show All
Windows Forms DataGridView - Invisible Cell Error
Hi, I have a potential problem with the datagridview. When I have an empty table, and start editing the first row, but press ESC to cancel the edit, I get an error "Current cell cannot be set to an invisible cell.".

I will, however, leave the question open for a while just in case someone from the community knows the answer to your question. ...Show All
Visual Studio package load failure in referencing external assembly
When my DomainModel project references (and uses) an external assembly, I get a package load failure. An example: - Create a new minimal language definition project - Add to your solution a class library project (ClassLibrary1), which will contain only the default project class (Class1) - Add a value property to any class in the domain model. Assign to the value property type a new symple type (namespace = ClassLibrary1, name = Class1) - Generate code and run. Package load failure happens when trying to load a language diagram. Is there any workaround Thanks, -- AFurtado Is this still the case, that external ...Show All
SQL Server Is there a way to protect an olap db meta data - technically
Hi we try to bild an olap db as core of a nsolution we provide and want to secure the olap db meta data. Is there a way to secure the meta data for the olap db technically (like a procedure in TSQL with encryption - for the whole SSAS DB) Because at the moment everyone with admin permission could connect by VS2005 and extract the whole solution. Best Regards HANNES I see. Unfortunately this is not possible yet with Analysis Services. Even theoretically it is bit hard to implement. Even if you were to encrypt your cube design with some key. You still need to provide such key to Analysis Server be able to decrypt it to read defini ...Show All

Software Development for Windows Vista SDK for low speed connection?
Far from the town, i have a low speed connection.. :-( For me, 1 Go is a dream I will never reach .....!!! Is there any other way to get the Last SDK You have two main options: Download the SDK using a download manager that can stop and resume if you have internet connection issues. Many will also allow you to set the priority of the download, so that it will not affect the total speed of your internet connection Download using the setup.exe. This web setup uses the power of Internet Explorer caching to download just some smaller individual files rather than the entire SDK at once. You may still experience some slownes ...Show All
Game Technologies: DirectX, XNA, XACT, etc. Where is DirectX going?
I read somewhere *cof* http://www.managed-world.com/SoonDirectXDirect3DNothingElse.aspx *cof* that Microsoft is deprecating a large part of DirectX (DirectInput, DirectSound) he then hints about learning Shaders http://www.managed-world.com/AdviceLearnShadersNow.aspx so the question is, should I not bother to learn DirectInput, DirectSound, etc... what should I be learning if I want to develop DirectX applications in the future is DirectX the future of graphics programming or is there something else coming (XAML anyone ) thanks for your comments heh heh.. I was just joking to myself that the next thin ...Show All

SQL Server Using error handling techniques in cursor routine
Hi everyone! I am trying to use error handling within a cursor routine. I have an Error Handling label outside the cursor that handles errors generated outside the cursor or when @@Fetch <> 0, but doesn't work for capturing errors inside the cursor routine. The cursor has a value that I am using for updating data. This requires a transaction for each pass. I also must select the max value of a selected field from the table where these updates occur. If an error occurs in any part of the transaction, I want to capture the error, select it from the sysmessages table, write it to a table, roll back the transaction and move to the next ...Show All

SQL Server Lowering priority on thread - SQL Server 2005 (64 Bit)
Hi all, Is it possible to lower the priority of threads running in SQL Server 2005 (64 bit) I know that the Kenn Henderson author of ; The Guru’s Guide to SQL Server series of books, have developed an extended stored procedure: xp_setpriority which does the work for 32 bit version (I presume it will work for the 32bit of SQL Server 2005). But I’m in need of using a similar work-around for 64 bit. My case is that I can have multiple jobs running on the SQL Server – slowing down the system, but need to keep an opening for a client 24/7 and not be late returning the records the client wants.
