• Visual Studio Express Editions Listbox Error

  I have two listboxes set up on one form. I have a button that once pushed I want it to compute the mean for the listbox that it's coded for. My problem is the info computes correctly for listbox1 but not for listbox2. I get an error that I'm converting from string to double on the second box. Also the data on the second box prints down in the middle of the box instead of at the top. Here is a copy of my code. Can someone tell me where I'm going wrong. Public Class Form1 Dim x As Single , y As Single , mean As Integer , sd As Single , a As String , z As String , p As Integer Private Sub TextBox1_TextChanged( ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox1.TextCh ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Homing missile (working on from the going beyong tutorial)

  I've worked a bit on from the going beyond tutorial and added another model to the project. My problem a bit matematical. How do i calculate which way the missile(with a vector3 position) should turn and when to stop turning when its pointing at another Vector3 position Extra credit question: I've added an background like they suggested in the tutorial. Even used the layerDepth parameter, and set that depth to 1.0f. as suggested. But my background still covers my models! How do i get it to actually being in the background The direction your missile should FACE is: Vector3 targetDir = targetPosition - yourPosition. If you're working in 2d, you can find the angle by doing Math.Atan(targetDir.Y / target ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Rants on XNA 1.0

  This is my first reaction when I installed and tried the 1.0 of XNA. To summarize my feeling: it's still 95% for XBox and no nearer to replace the old MDX 1.0. So I decided not to migrate from MDX to XNA though I want to do that very much. I feel like MDX 2 more; amen to MDX 2. The hardest issue for me is the content pipeline, which is very necessary, but the workflow is fixed and it assumes the contents are only built before the program runs. The helper functions wrapping D3DX can only be used with types in the content pipeline. I have to utilize the full content pipeline just for generating something dynamically, of course with significant performance cost. Or I have to write those D3DX utilities my self. Currently I don't have a good id ...Show All

• .NET Development Socket transfer of TIF results in unreadable TIF file.

  Hi everyone, bare with me, this is my first post here. Currently, we have a program that connects to a server and retrieves three types of files (TXT, CSV, and TIF). The program now needs to be in VB .NET without changing the server code. In my code below, I can successfully receive textual files (TXT and CSV) files byte-for-byte without a problem. The resulting files work perfectly too. However, when I try to retrieve the TIF, my program outputs the correct number of bytes but the file is corrupt. I was wondering if anyone can point me in the correct direction. <CODE> Public Function readFile(ByVal strBuff As String, ByVal fileSize As Int32) As String Dim returnData As String = "" 'Holds returned data from s ...Show All

• Smart Device Development Dose CE 6.0 provide Multi-user interface support

  I try to develop the Multi-user login screen like the one provided by windows xp. I don't have the idea whether CE 6.0 provides this functionality or not. Somebody help please , I'll appreciate!! Windows Embedded CE 6.0 provides some 'multi user' support. You'd need to customize the Startup UI component to implement this kind of functionality.

• Game Technologies: DirectX, XNA, XACT, etc. General strategy question about XNA

  What is MSFT's strategy with GSE I mean, is it a stripped-down version of GS Pro meant to spark interest in GS Pro Is it actually going the core of GS Pro, and the hobbyist/student community is acting as both first adopters and beta (or even alpha) testers of the product Is it a way for MSFT to foster some kind of indie/small game shop Xbox360 game development (The latter would seem to be slightly odd: the actual dev kits, I gather, are not a minor expense, in addition to what I'm assuming are certification and any other testing expenses; I would think that releasing an alternate path for Xbox game development might cannibalize an existing revenue stream...) It would seem to me to be just simpler to wait for GS Pro to come out, and l ...Show All

  i saw this thing on something called xna racer, and it amazed me that we could do this with xna http://www.kotaku.com/gaming/xna/clips-xna-racer-preview-213594.php does anyone know anything about getting this What if I'm just a PC user Will I be able to get my hands on that starter kit I'm currently learning and using XNA, and I really want to continue using it, but I don't own an XBOX 360, nor I plan on buying one because I've always been a PC gamer.

• .NET Development Binary Serialization of CollectionBase

  I have just hit a brick wall whilst building custom binary serialization for my object graph. The issue I am having relates to the Deserialization of a collection. The "Designs" collection inherits from CollectionBase. The items stored in the Collection of the type "Design" The class "Design" Inhertis "PhysicalJobEntity" which Inherits "JobEntity" I inherit the class "Design" to create any type of object whether it be a truck, house or can of drink. So to paint a clear picture I will use an example. I create three classes "Truck", "House" and "Drink". All of these inherit from design. I run the app and create 1 instance of each of these cl ...Show All

• Windows Forms Ascii File Save Problems

  Hi, In my game I am saving the data in an ASCII file using the Streamwriter function. The data is saved automatically during play (every X minutes of game time) and also when the player exits the main display form. (The user is never prompted during file save and the data is saved to a fixed file name and folder). The ASCII files can range in size from a few KBytes to 3-4 MBytes. During game play there are no problems with this file save. However, some players are experiencing intermittent problems with the file save triggered by display form exit (I call the file save during the FormClosing Event). Always when there are problems then the data written to the file is incomplete - perhaps as much as 10% can be missing. The data does ...Show All

• Commerce Server Everything's going great, except ...

  Hi All. I'm doing my first CS2007 installation and I've got 3 main problems: 1. can't use the OrdersWebService (please see my earlier post at http://forums.microsoft.com/MSDN/ShowPost.aspx PostID=1093625&SiteID=1 ) 2. I can open the CatalogManager but the "Tasks" panel is empty/closed/unavailable. I guess this is a permissions thing but I've been through it again and again and I can't see anything obvious (of course) 3. I can't open the MarketingManager - I get "you are not authorized to use this web service". Another permissions problem, but where I've made sure to add myself to the MarketingManager authstore as administrator, made sure I can write to it, can use the Marketing web service, but no luck. ...Show All
