• Game Technologies: DirectX, XNA, XACT, etc. Render target save'n'restore

  I've a func that do some work including rendering into rt. So, i need to save old rt at the beginning of my rendering, and then restore it at the end ( when smb call my func, he may have rendering to texture enabled, or just rendering to the backbuffer, and he don't wont to worry about restoring his rt after call of my func ). Is there any way to implement such a behaviour using XNA Not sure it will help, but the common approach for working with RT's in XNA is like this: 1) Create a RenderTarget2D in a device supported format 2) While rendering call GraphicsDevice.SetRenderTarget( 0, renderTargetThatYouJustCreated ) 3) When done rendering restore the old backbuffer by calling GraphicsDevice.SetRenderTa ...Show All

• SQL Server Client Certificates with SQL Mobile replication

  I am currently trying to replicate a SQL Mobile 2005 database with a SQL Server 2005 database through web synchronization using SSL Server AND Client Certificates. On IIS, with "Require Client Certificates" unchecked, I can replicate fine. Once I turn it on, I get a message from replication saying "A Secure Socket Layer connection is required to access this site". I have installed a client certificate in IE, and can access the https:// servername /Ojt/sqlcesa30.dll site (I tried removing the client certificate, and I was denied access, then reinstalled it and it worked - so I think that part is working). Does anyone have any experience with this My production operating environment requires client-side certificates. ...Show All

• Visual C++ How to avoid rebuilding

  Hi, I have a header file which is included by some fifty odd files..If i even make a small change as adding a comment to the header file a rebuild is taking place.. Will the pch file resolve this issue..by including that header file in stdafx.h Please help me on this.. Thanks & Regards, AFAIK if you change teh header file, it means that, there are some changes in specific definitions. Unfortunately C++ compiler is not that much smart to handle changed areas . if you change header file, and if you include it somewhere else, that file will also will be part of compilation. else your change will be void. The changes are made in the stdafx, most of the cpp file will recompiled because precompiled header are used by most of the CPP fi ...Show All

• Visual Studio Express Editions C# and the game loop

  My primary interest in learning C# is to write games and yet it appears that much of the C# beginner tutorials focus code that is largely event-driven. I also caught a few discussions in blogs recently that had a intense debate on how to get C# to properly execute a real-time game loop and from what I could discern of the discussions, this task seemed to have an air of in-depth "hacking" about it - as though C# is simply not designed to do things this way. The discussions on the blog sites were also very unclear on the topic of game loops and as a relative beginner, the explanations behind the issues were simply beyond me. Now given that C# is being hailed as a great language to create games, how come there's no clear discussi ...Show All

• Windows Forms Stopping long running SQL in OleDb

  I have a program that will execute various SQL statements and return their results to the user. On occasion the user will enter a SQL statement that will cause them to sit for a while waiting. In such cases I want to give them the option to cancel the request that they made.

• Visual C++ CLIstCtrl in CRecordView

  Hello, I have placed a CListCtrl onto a CRecordView of an SDI app. I have tried to get to the messaging produced by the horizontal and vertical scrollbars of the CListCtrl object. The scrollbar events do not seem to get trapped by any message in the CRecordView. I have tried OnNotify(), OnHScroll(), PreTranslateMessage(). Spy++ shows WM_HSCROLL/WM_VSCROLL messages are produced in the CRecordView, but they don't seem to get routed through the above message handlers. What do I need to do for the WM_HSCROLL/WM_VSCROLL messages to pass through an appropriate message handler in my CRecordView Any help would be helpful :-) Thanks!

• Visual C# win. service, config sect. handler, & security settings?

  I have a section handler that reads in plugins to load. everything works fine when I run the app as a stand alone (on my computer & the common dev box), but when I run it as a service (on the dev machine) it fails. here's where it fails. the section handler loads plugins. for each plugin, i recursively walk the assembly's dependency tree and load up any assemblies that havent been loaded. it starts by caching everything in the app domain before any plugins are loaded. then all assemblies & their containing types are cached. I use that cache data to load the assemblies & reference their types inside the section handler. when it runs as a service, it doesnt load the plugins. I have added the following a ...Show All

• SQL Server Encryption and bulk insert

  Hello, I need to build a table with encrypted data with the source data coming from a .csv. The account number from the .csv will need to be encrypted in the final table and I will also need to have a hashed or MAC index on the account number. I'm guessing that I can do this with a stored procedure using a temp table to load the unedited data and then load the actual table from there. The table will be built from a download every evening. The key and certificate for the encryption are already set. I have been able to load data directly to the table providing values. But, I have been struggling getting a bulk insert to work. I'd appreciate any ideas or examples. Thanks! Could you please explain w ...Show All
