• Game Technologies: DirectX, XNA, XACT, etc. Dynamic for-loop in HLSL Pixel Shader

  Hi there, does somebody know if (how) it is possible to use a for loop in a HLSL pixel shader with a dynamic count For example: int count = 5 / a; for (int i = 0; i < count; i++)     ... I didn't manage, whatever I tried the effect creation fails. Even with shader model 3. Nico Suddenly it works! I don't know what I made wrong before. Anyway, when compiling a shader with a dynamic for loop there is a lot of preprocessing. Does anybody know what is going on The more I limit the dynamic count, the shorter the preprocessing. I just waited about 5 minutes for a loop with a count limit of 80 to compile (!). So my sha ...Show All

• .NET Development How do I programatically set the DataConnection if using Visual Basic 2005 Express?

  I'm using Visual Basic 2005 Express Edition and have created a project and statically linked it to existing data in an Access 2000 database. VB 2005 Express opens the database (visible in Data Sources pane) when I start the project explorer. That's fine while developing, but once the app moves into production, it needs to find the database location from a registry key and then open the db from the appropriate location. I know how to read registry keys within the app, but I don't see any code pertaining to opening the database within my current app. Under Solution Explorer, I see an app.config file containing XML code. That code cont ...Show All

This app will not be a traditional MDI app as there will not multiple instances of some forms, such as a login form, an about form, a splash screen and a change password form. I still want these forms to have a certain startup position in relationship to the MDI ...Show All

• SQL Server large tables overflow rows

  In SS05, I see that I can get more than 8KB on a page. Has anyone tried this -- will it hurt performance a lot Is it useful. Do you recommend it Hi Learningdba,   Larger rows will always hurt performance, since more I/O is required to handle the same amount of rows.   On the other hand - if you NEED to store that many data, than SQL Server 2005 handles it a lot better than SQL Server 2000. The text and image datatypes were, frankly, quite a pain to manipulate. varchar(max) and varbinary(max) are an enormous improvement.   -- Hugo Kornelis, SQL ...Show All
