• Game Technologies: DirectX, XNA, XACT, etc. Specular reflections aren't working right

  I'm having a problem with specular reflection.  It flickers as I move around my object. Sometimes when I'm looking at a face, and I swivel the camera just a few degrees, I get specular reflection.  When I swivel a few more, the reflection is gone - leading to the flicker. But specular reflection is only based on the position of the camera, not the direction it's looking.  So it confuses me that swiveling the camera would change the specular reflection in any way, much less so drastically. Also, I find it confusing that I should see specular reflection at all ...Show All

• .NET Development socket.Receive() on blocking socket throwing WSAEWOULDBLOCK exception?

  I'm using a UDP socket for network communication with socket.Blocking == true and SocketOption(ReceiveTimeout) set. After several thousand packet exchanges, socket.Receive() starts throwing WSAEWOULDBLOCK (SocketException.ErrorCode == 10034) and seemingly continues to do so indefinitely about every second or third call to socket.Receive().   Can someone shed some light on what might cause socket.Receive() to throw a WSAEWOULDBLOCK exception on a socket with Blocking == true I wouldn't expect a WSAEWOULDBLOCK exception on a blocking socket. This is happening with .Net 2.0 Beta2 on WindowsXP Pro with service pack 2 (and updates). T ...Show All

• Windows Forms How to serialize with TreeView?

  How to serialize with TreeView in .NET 2.0 Well, it's apparently not a good idea to serialize a UI component like a tree view, instead, you should serialize a data structure that represents the tree view. The problem with serializing a TreeView (or any other UI component) is that if you have to deserialize it, you have to remove the old version of your tree view and replace it with the deserialized version.  Which is anoying because if you created your form with the form designer in VS 2005, then you have to syncronize all your settings with the deserialized tree.  This is really anoying during des ...Show All

• Visual Basic Try...Catch statement Question

  I have a Try...Catch statement that contains 12 Operations inside it. On the catch I want to display a msgbox that tells exactly which operations failed. I was looking through the exception methods and couldn't find one that worked. All of the methods provided relative information but nothing specific. The reason I want to pinpoint exactly which operations failed is so that the user can email the error message to me and when I get it I will know exactly how to fix it. Thanks. Hey Troy. . . Lets go an entirely different direction!!! Lets let the wonderful Windows.Forms namespace work for us!!! play along with me - create a ...Show All

• Windows Forms How to debug data adapter fill errors

  Hi. I've got a C# application that uses an ODBC connection to retrieve data from a DB2 database. When running the application I get the following error: [OdbcException: ERROR [HY000] [IBM][Client Access Express ODBC Driver (32-bit)][DB2/400 SQL]SQL0802 - Data conversion or data mapping error.] Now it just so happens that this application is designed to retreive the data through a mail merge in word.

  Hi, I read that views can't be published with SQL Server 2005 replication. Is this planned for the future If not what alternatives are there for this Simple collecting the data needed in a new table ain't a solution for us (memory consuming). And joining the data on the PPC ain't a good solution either (memory and time consuming). We only want to pull the data. Greets, Ivo Klerkx Just to confirm your statement, it is true that (other than the INFORMATION_SCHEMA views) there is no support for other user-creatable Views in SQL Mobile, whether they are created on device or on the server/replicated ...Show All
