• .NET Development Safely pass data from a socket's BeginReceive method?

  Hey there! I'm writing a class called "Connection" that creates a telnet connection to a server, and I'm using a socket to handle the connection. I use BeginReceive to asynchronously receive data, and an event to pass the received data to anything handling it. Here's the sub that handles data receiving: Private Sub OnReceiveData(ByVal ar As IAsyncResult) Dim s As Socket = DirectCast(ar.AsyncState, Socket) Dim ReceivedBytes As Integer = s.EndReceive(ar) If ReceivedBytes > 0 Then RaiseEvent ReceivedData(Me, ASCII.GetString(Buffer, 0, ReceivedBytes)) Sock.BeginReceive(Buffer, 0, Buffer.Length - 1, SocketFlags.None, New AsyncCallback(AddressOf OnReceiveData), s) Else Disconnect() End If End Sub Now, when I mad ...Show All

• .NET Development ConnectionString.InitialCatalog or Connection.ChangeDatabase

  Hi If an application connects to two databases on a Sql Server 2005 instance, is it better to specify the database in the ConnectionString.InitialCatalog property or to select the database after a connection has been established by using the Connection.ChangeDatabase method I'm assuming that the ChangeDatabase method is better because it will create a single database connection pool instead of two database connection pools. Is this correct Thanks It's better not to base this sort of decision on the current implementation, as this is the sort of thing that is liable to change in future versions of the framework. Personally if I've got two databases then I'll define two connection string ...Show All

• Windows Forms searching..........

  Hi can someone point me in the right direction of searching multiple drives and subdirectories for files. It would be good if it was not a so accurate search eg. if I entered bobby in the text box, it would still display bobbybrown.mp3 in the text box. so it like will find words that are similer. Oooh,no, what I just gave you is a clue, you must translate all my c# code to VB.net code, let me translate it for you.

• Game Technologies: DirectX, XNA, XACT, etc. Is Boo a viable option for Scripting for both PC and XBox360?

  I'm just wondering if anyone has tried getting Boo to work for scripting on the XBox360, or is there some feature that Boo takes advantage of on the PC that isn't available on the console I've been reading that IronPython isn't an option, and LuaInterface wouldn't work either, since P/Invoke doesn't seem to be supported for security reasons. Can anyone shed some light It would be greatly appreciated. Thanks, Kevin As you mentioned, the reason LuaInterface doesn't work on the Xbox 360 is because LuaInterface uses native code (via P/Invoke). IronPython uses dynamic code generation (System.Reflection.Emit) which is not supported on the Xbox 360 framework. The best place to find out if you can use Boo is to a ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Are there any Notification callbacks in the Audio API?

  Been looking through the help and I don't see any way to find any information on a playing audio clip. This is pretty critical if you are trying to sync animations up to the audio. There is a .GetVariable method on the Cue object, but that appears to get a static variable set in the XACT project. I see a promising variable named 'Distance' in the XACT project, but when I query that while the audio is playing I get back 0. So, is there any way to get some information on how far along a clip is playing I think the DirectX api has a WavePlaying callback or something like that. Any hope of that making it to XNA Just thought I would ask here before going to the connect site. Notifications for XACT were cut fr ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. CreateFromAxisAngle???

  I'm trying to get a sprite to rotate around a point, but it's moving in a straight line instead of an arc. My code looks something like this: Vector3 n = Vector3.Normalize(new Vector3( originX, originY, 0.0f)); Matrix rotationMatrix = Matrix.CreateFromAxisAngle(n, degrees); Vector3 rotatedPointV1 = Vector3.Transform(v1, rotationMatrix); where (originX, originY) is the point I'm rotating around and degrees is my angle of rotation. I'd like to move the sprite to rotatedPointV1. What am I doing wrong If you want to rotate a sprite around a point in the sprite's local coordinate system (for example, to get the sprite to rotate around it's center point instead of it's upper ...Show All
