• Game Technologies: DirectX, XNA, XACT, etc. Early Out

  Hi. I tried at the "regular" DirectX forums but since there was no answers or even faint ideas I am gonna post my question here. I have a fairly simple shader which loops over a numer of calculations. With ps_3_0 can we exit an loop and the fragment program early on if a certain condition is obtained for( ... ){ if( b > constant ) return Output; } } return Output; The compiler tells me that it doesnt support asymetric returns. For reference I will post a little more of the shader which causes the compiler to complain: for ( int i=0; (i<iStepsViewRay); i++){    ...Show All

• .NET Development X509 key not loaded correctly for FTPS server authentication ?

  I have written an FTP service in VB.NET. Am attempting to add SSL authentication. I believe it is either not doing the handshake correctly, or else it does not like the way I loaded the server certificate.  Let me paraphrase the salient portions of code to show what I am doing, and the resulting exception: Public SSLCertificate As X509Certificate SSLCertificate = New X509Certificate("D:\TEMP\MyPrivateKey.pfx", "myprivatekeyspassword") Private mTCPClient As TcpClient (client connection has been negotiated in clear text at this point - I ensure the socket is clear of all available data prior to attempting to negotiate) Private mSSLStream ...Show All

• .NET Development SerialPort Class Help DataReceived

  I'm using the DataReceived from the V.2 .NET SerialPort class. I'm communicating with a microprocessor board and i can write to it fine. I'm having trouble reading from it. It sends a single byte at a time without an EndCharacter. I can see the byte being sent on my oscope and with an older Turbo Basic program it does read the byte. My problem is that my DataReceived event isn't being thrown. I have my ReceivedBytesThreshold set to 1 and i still can't see anything. Here is my code just see if the event can be thrown: Private Sub SerialPort1_DataReceived( ByVal sender As Object , ByVal e As System.IO.Ports.SerialDataReceivedEve ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Still using Visual C++ 6.0? Try Visual C++ Express Edition with DirectX!

    This is just a short, friendly post to encourage all of you still using an 8 year old C++ compiler to consider using today's new release of Visual C++, including the free Visual C++ Express Edition!   Why move away from Visual C++ 6.0   The list of improvements is extremely lengthy, even for the express edition, but here's a few key reasons for those of you writing DirectX-based software: 1) The latest SDKs no longer with with Visual C++ 6.0 2) The Express Edition is free, and includes the same complete, optimizing version of the C++ compiler that you get in the higher level versions of Visual Studio 2005.  Read here ...Show All

• Software Development for Windows Vista Binding workflow parameters with activity properties

  Can someone provide a code snippet to show how to bind workflow parameters with (custom) activity properties. Note that the workflow is to be composed dynamically. I am trying to compose a WF dynamically by stringing together certain predefined activities that have some properties defined on them. I would like the WF to take certain parameters such that they are bound to appropriate properties in the activities (.i.e parameterizing the activities). As much possible I would like to use a built-in WF class like for eg. SequentialWorkflow class (and not define a custom WF class) for constructing my workflow. thx Jay ...Show All
