• Game Technologies: DirectX, XNA, XACT, etc. Using an array in a vertex shader

  My understanding is that a vertex shader works on a single vertex at a time. If that's the case, I'm confused about how to call a shader using values that are in an array. Say I have a mesh of ten vertices, and I have a an array of 40 vector3's. Each index in this array contains a unique vector value and corresponds to a vertex in the mesh, so, the array represents four frames of data that I want to use in a calculation within a vertex shader How is it done Like I said my understanding is that the shader operates on a single vertex at a time, so I can't pass the whole vector3 array to the shader. I have to get the right index, and pass that value to a vector3 global in the shader, which doesn't sound like a big deal, right The problem is ...Show All

• Visual Basic Making my programs executable?

  I am fairly new to programming, and going to college for Software Engineering (just started); I was just wondering once you get all the code written out, and everything in place like you want it, how do you convert it to an .exe to where it will run on any machine Any help would be appreciated! You cannot do this in .NET anything created in .NET requires its resources/libraries (ie the .NET Framework) in answer to your question, you would need to create these applications in VB, C++ or VC++ VB is now outdated and replaced by VB.NET, everything is going .NET now :-) As said before, in the future you will not need to worry about having .NET on the computer since .NET is almost now a standard feat ...Show All

• Windows Forms Form doesn't have focus when its DialogForm closes.

  Hi all, I have a Form (Form1) that opens another Form (Dialog) when a button is pressed, but when this Dialog Form is closed, the Form (Form1) that opened this doesn't have focus and I have to tap the screen (Using PocketPC) twice inorder for any Control on the Form to get the focus and react to my actions. I have the following code in a method... if (frm != null) { if (frm.ShowDialog() == System.Windows.Forms.DialogResult.OK) return true; else return false; } ... that opens the forms, but this code is contained in a class and is called from the event on Form1. Is this the cause (the form open call being in another class ) As I don't get this problem anywhere else in my application. Even if I put in a statement that sets a control on ...Show All

• Software Development for Windows Vista Some questions

  Hi, Some generate questions: 1) For Sequential Workflow, I can track the Instance History without using SQLPersistenceService, but for the Statemachine workflow, I must start the SQLPersistenceService before I can get the tracking history, is that true 2) In Beta 2.2, I remember we have the script to create the SharedPersistenceAndTracking database. But for the RC version, where can we get the Sql Script to generate the Shared store 3) After the workflow completion, we can get the Output Properties within the workflow instance with e.OutputParameters("ClaimAmount"). But before the completion, how can be get the properties (such as the Claim Amount we send to the workflow when we start the workflow) from the Workflow T ...Show All

• SQL Server Sending email to multiple recipient

  I am trying to send emails to multiple recipient using the Send Mail Task, but it is failing with the error: " The specified string is not in the form required for an e-mail address." It works when I have only one emailID in the ToLine, I have a script task that build the emaiID list and saves it in a variable and the in the Send Mail Task, I am using the Expressions for ToLine to use this variable. If there is just one emailID in the list, everything works, but if there are multiple, it throws an error. For building the emailID list, I tried using "," as well as by ";". But none seem to work. Any help will be greatly appreciated. The Send Mail task likely doesn't su ...Show All

• Visual C# Compiling under dualcore systems

  Is it possible to get Visual Studio to use the full capabilities of multiple processors and/or dualcore processors I have a project in Visual Studio that takes 4 - 5 minutes to compile, and during the entire time, it's only using 50% of the available processor power. Obviously it's going to take time for the compiler to be upgraded to support multiple cores and multiple processors, but is it possible to at least compile two files at the same time - a copy of the compiler running on each core/processor One of the projects in question is a Visual C++ project with just over a hundred cpp files. The machine used to compile the project is a AMD X2 4800 with 2GB of RAM. Only Visual C++ can do multiprocessor ...Show All

• SQL Server Hierarchy Parent-Child

  Hi. I have a parent-child relationship in a table, by making use of an ID, and Parent ID. Firstly how do I manually change, or setup this hierarchy. Secondly, how do I do a rollup, along this hierarchy, sothat I can retrieve the aggregate values, using MDX I thank you in advance for your feedback. Hi. Sounds like you should start with the basics in Analysis Services about parent-child hierarchies. Here's a link to MSDN on-line which explains how parent-child hierarchies work in SSAS 2005. The subsequent links at the bottom of the page can guide you to more detail on creating the parent-child hierarchy in BI Studio. http://msdn.microsoft.com/library/default.asp url=/library/en-us/olapdma ...Show All

  Our company written a marco that used in MS Words and it as same as the "insert -> picture -> from file" dialogue, but we want to enhance it to get the filename automatically when the dialogue box is opened to instead of blank. Hi, Looks like the built-in dialog does not take a initial filename argument. You can change the folder using, Options.DefaultFilePath(wdPicturesPath) = "C:\" Instead try the Filedialog object.

• .NET Development Trace.Refresh() call fails

  Hello all. I am trying to catch changes in my app.config file and refresh Trace class on any change. I am using FileSystemWatcher class instance to be notified about any change.

I tried to edit app.config from FarManager application's editor and from notepad. How i can refresh the Trace object without getting this exception Thank you Yes. It seems your guess was correct. I tested TraceSource instance with Trace.Refresh and it is updated. Very said news, since it forces me to create a single-tone object in the code while i have a built-in one. Hope t ...Show All

• Visual Studio Tools for Office Features or Bugs in VSTO.

  Are these features or bugs I've found two things that there may be a reason for but I can think of none. 1. If you have a form field in a word document project that has a default value in it. You cannot populate that bookmark in code with a bookmarkname.Text = "AAA" line of code. It gives you an error along the lines of "Out of Range" or something like that. 2.
