• Game Technologies: DirectX, XNA, XACT, etc. Can DX10 card emulate DX9 card?

  Hi masters,   I have two noob questions. Can a DX10 Card emulate a DX9 card for easy backward compatibity Can DX10 APIs emulate DX9 APIs   why     Best regards.. There is no emulation needed. Vista fully support Direct3d9 - it has to for the Vista shell. Therefore any D3d10 card must also fully support d3d9 D3D10 APIs do *not* support D3D9 calls in the same way that D3D9 supported previous APIs. D3D9 is provided and fully supported on vista so if you want to support both you must code that into your engine. ...Show All

• Visual Basic Updating multiple tables from one form using TableAdapters

  Hi, I am new to VB.net but have been programming in other languages for years. TablesAdapters are new to me... Most of my forms have one tableadapter on it - or only one that updates. Those work fine. However I have one form that is like a master form that needs to insert records to several different tables. For instance - there is the customer table which has a one to many relationship to the job table (on cust_id) which has a one to many relationship to the job_details table (on job_id). I have filled them with the tableadapter and added a new record. When I go to save this data to the database, the customer table updates cor ...Show All

• SQL Server Transactional Replicating hanging SQL Server 2005

  Hi, It appears that every 5 or so days, my transactional replication is hanging.  I see that I have a couple thousand undistributed commands and this number keeps growing.  It forces me to generate a snapshot in order to sync up.  When generating the snapshot, I will get frequent messages like "waiting for a response from server...".  So I will keep stopping and starting syncronization.  Eventually the snapshot will go out, with a delay after generation.  Has anyone experienced this   Your help is much appreciated. Thanks, Nick What do you mean "hang"   ...Show All

• Windows Forms Dynamically creating user-scoped settings...

  How do I programmatically persist settings in an ApplicationSettingsBase-derived class   The ability to create type-safe user-scoped properties at design-time is great, but I need to allow third party controls to create them at runtime.  I've also tried adding a UserScoppedSetting of type NameValueCollection and adding values to it at runtime, but the values don't seem to be persisted.
