• Game Technologies: DirectX, XNA, XACT, etc. HLSL Lighting vs FFP Lighting

  Hi there, I am trying to re-implement my fixed function lighting code in my shader effect. However, I am getting different results. They are similar, but not the same. Below is the code. FFP Code //material values this .mMaterial.Diffuse = Color .White; this .mMaterial.Specular = Color .LightGray; this .mMaterial.SpecularSharpness = 15.0F; //light values device.Lights[0].Type = LightType .Directional; device.Lights[0].Diffuse = Color .White; device.Lights[0].Direction = new Vector3 (0.8f, 0.0f, -1.0f); device.Lights[0].Enabled = true ; HLSL Code //global variables float4x4 g_WorldViewProjMtx : WORLDVIEWPROJECTION; float4x4 g_WorldMtx : WORLD; float3 g_LightDir; float4 g_LightCo ...Show All

• SQL Server Cursors - Curse or blessing?

  Could someone elaborate on or describe a circumstance when a cursor could be beneficial and when using a cursor would be a bad idea Adamus CURSE! Understand where I came from: I worked with Sybase before MS got the code and at one time the manuals were almost word-for-word identical. When Sybase came out with te release that included cursors my bosses boss mandated that we use cursors pretty much any place we could. Most of the developers in our organazation just blindly started using them. I started finding that they ran slower. About a year after all of this I started to look for a new job. MAN, I couldn't believe it, but in every single interview -- and I mean literally every one -- I got asked if I knew how to use cursors. ...Show All

• Commerce Server Extending Commerce OrderForm

  We have extended the OrderForm with a Strongly-Typed property ("OrderType") via the OrderObjectMappings.xml file and run the tool to update the scripts and OrderForm table. We have created an inherited Commerce Order Form Class which inherits from the Microsoft.CommerceServer.Runtime.Orders.OrderForm Class. The skeleton of the class is as follows: protected CommerceOrderForm(SerializationInfo info, StreamingContext context) : base(info, context) { m_dtmOrderDate = info.GetDateTime("OrderDate"); try { m_strOrderType = info.GetString("OrderType"); } catch (SerializationException) { m_strOrderTy ...Show All

• SQL Server Replaceable parameters in Subscriptions

  I see when creating a subscription that you can use @ReportName and @ExecutionTime in the subject and comment areas. Does anyone know if there are other @ items that can be utilized (This question was posted by JackBoughson on 07-16-2006 but that thread went astray and the question was never answered). Scott Thank you, I understand. However, I am not looking to extend the behavior. I am looking for documentation on other built-in @Values - it is unlikely that there are only two. Scott ...Show All

• Visual Studio 2008 (Pre-release) frameworkelementfactory grid columndefinitions

  hello, How do you define the columns and rows for a grid, when using a FrameworkElementFactory e.g. FrameworkElementFactory f = new FrameworkElementFactory(typeof(Grid)); f.SetValue(Grid.ColumnDefinitions, newNiceColCollection); except that Grid.ColumnDefinitions doesn't exist. FrameworkElementFactory has some custom logic for handling the ColumnDefinitions and RowDefinitions in a Grid. For those values, you treat them like children in the factory tree, for example: FrameworkElementFactory gridFactory = new FrameworkElementFactory ( typeof ( Grid )); FrameworkElementFactory columnDefinitionFactory = new FrameworkElementFactory ( typeof ( ColumnDefinition )); columnDefinitionFactory.SetValue(...); ...Show All

• Visual Basic DES File encryption problem

  Hello everyone. I'm working on a project that performs file encryption. With DES and 3DES. However I've been having a problem encrypting compressed files. The code that I used was a snippet that I found in the MSDN, this code seems to work perfectly with text files. I even analyzed the text files on a binary level and everything was perfect. Now whenever I try to encrypt a *.rar or a *.zip file I always get a "The file "" header is corrupt" and/or "Unexpected end of archive" errors. This is the code for the encryption and decryption algorithms: Sub EncryptFile(ByVal sInputFilename As String, _ ByVal sOutputFilename As String, _ ByVal sKey As String) ...Show All

• Visual C# How can I parse: name="My Value" into a Dictionary? (or other collection object)

  Let's say I have a long string like such: string s = "value=\"Hello World\" value2=\"Hello Goodbye\""; How can I put that into a collection object (eg. dictionary ) so I can access "value" and it would equal "Hello World" (WITHOUT the quotation marks) So... value = Hello World value2 = Hello Goodbye I'd like to access it something like: obj.GetValue("value") and it would return Hello World no worries, in future, its best not to delete the topic (unless its a multiple post) as other users who may have a problem like you had, could find the solution here :-) glad you got it ;-) ...Show All

• .NET Development How do I ensure async calls to a remote server are delivered in sequence?

  Hi there, I have a Singleton remote service object, and I'm invoking a method on it asynchronously from another process by using BeginInvoke. However, sometimes calls are delivered to the method in a different sequence than they were made by the calling process. Is there a way I can ensure that calls are delivered in the same order as they were made by the client, without having to make the client stop and wait for each call to return Thanks Alistair ...Show All
