  • Moving Character in C# XNA Not working

    - by Matthew Stenquist
    I'm having trouble trying to get my character to move for a game I'm making in my sparetime for the Xbox. However, I can't seem to figure out what I'm doing wrong , and I'm not even sure if I'm doing it right. I've tried googling tutorials on this but I haven't found any helpful ones. Mainly, ones on 3d rotation on the XNA creators club website. My question is : How can I get the character to walk towards the right in the MoveInput() function? What am I doing wrong? Did I code it wrong? The problem is : The player isn't moving. I think the MoveInput() class isn't working. Here's my code from my character class : using System; using System.Collections.Generic; using System.Linq; using System.Text; using Microsoft.Xna.Framework; using Microsoft.Xna.Framework.Graphics; using Microsoft.Xna.Framework.Input; namespace Jumping { class Character { Texture2D texture; Vector2 position; Vector2 velocity; int velocityXspeed = 2; bool jumping; public Character(Texture2D newTexture, Vector2 newPosition) { texture = newTexture; position = newPosition; jumping = true; } public void Update(GameTime gameTime) { JumpInput(); MoveInput(); } private void MoveInput() { //Move Character right GamePadState gamePad1 = GamePad.GetState(PlayerIndex.One); velocity.X = velocity.X + (velocityXspeed * gamePad1.ThumbSticks.Right.X); } private void JumpInput() { position += velocity; if (GamePad.GetState(PlayerIndex.One).Buttons.A == ButtonState.Pressed && jumping == false) { position.Y -= 1f; velocity.Y = -5f; jumping = true; } if (jumping == true) { float i = 1.6f; velocity.Y += 0.15f * i; } if (position.Y + texture.Height >= 1000) jumping = false; if (jumping == false) velocity.Y = 0f; } public void Draw(SpriteBatch spriteBatch) { spriteBatch.Draw(texture, position, Color.White); } } }

  • Need help to install Ubuntu on Win7 Alienware M17xR3, installing not working

    - by Rodrigo
    Please I need help to install linux on my computer to start analyzing Next Generation Sequencing (molecular genetics) for my work. I've tried to install from all different ways and forms and it gave me different errors. First I will describe my system: Alienware M17x R3 Raid Drive 596GB (2x 298 GB) Windows7 primary partition C: The hardrive is divided in 3 primary partitions (can't do 4 don't know why) 1st: Fat16 no name capacity 40mbs almost not used (has files like command.com, dellbio.bin, dellrmk.bin and oobedone.flg) I dont know what this is for but is blocked and non system (Status:none). 2nd: Recovery NTFS 9GB (Status:system) and it seems to have boot files. 3rd: CD: Windos OS (status:boot). And I have 2 Logical drivers F: data for backup and games :D (300gb) G: For trying to install the Linux (Already tried with Fat32, Ext2, ext3 and ext4) Installing with Wubi on F: and G: Instalation looks good on windows ask to restart dos mode appears: try (HD0,0) non-ms:skip try (HD0,1) NTFS5: No Wibildr try (HD0,2) NTFS5: Error: "Prefix" is not set. Installing with Wubi on C: Installation looks good on windows ask to restart dos mode apears: Mount denied becouse NTFS volume is already exclusive opened, the volume may be already mounted or another software may use it which could be identified for example by the help of the 'FUSER' command Mount devdm-4 Could not find installation files /ubuntu/install custom-installation Run 'Chkdsk /r' on windows and restart...blablablalba... that should correct. done this didn't work. Tried installing with USB drive and after burning a CD with the Iso file download from the official website: I've tried the option to install along windows with a G: drive in FAT32, EXT2,3 and 4, I've tried to leave unallocated data, without the driver G at all... appears this everytime: http://i.stack.imgur.com/eo2Ie.png pres ok it ask me to: Not possible to install the boot loader at the location: specify new location: I've tried to select all the drivers non is accepted If I ask to continue without installing the boot loader he ask me to install later by myself which I'm trying to figure it out but I'm not really good to understand how ppl get to the programming part like a DOS to write down couse I'm a newb and I've dont work on dos or linux before... I've read that the boot loader has to be installed on the primary partition, but I'm not sure what I can delete from those 2 partitions that would let me get 1 extra... and it seems that the one that windows use is protected to write down so the software is not touching it... Please if someone have any idea to help me out... I've got a course tomorrow of how to use the software to analyze the data and I wanted to take my computer with me, so I've passed the last 3 days trying to search different ways to solve. My question is also post on the bugs.launchpad.net link here: lounchpad.net bug #882695

  • Send HTTP Post with default browser with C#

    - by Paul
    Hello, I am wondering if it is possible to send POST data with the default browser of a computer in C#. Here is the situation. My client would like the ability to have their C# application open their browser and send client information to a webform. This webform would be behind a login screen. The assumption from the application side is that once the client data is sent to the login screen, the login screen would pass that information onto the webform to prepopulate it. This would be done over HTTPS and the client would like this to be done with a POST and not a GET as client information would be sent as plain text. I have found some wonderful solutions that do POSTS and handle the requests. As an example http://geekswithblogs.net/rakker/archive/2006/04/21/76044.aspx So the TL;DR version of this would be 1) Open Browser 2) Open some URL with POST data Thanks for your help, Paul

  • Low coupling and tight cohesion

    - by hidayat
    Of course it depends on the situation. But when a lower lever object or system communicate with an higher level system, should callbacks or events be preferred to keeping a pointer to higher level object? For example, we have a world class that has a member variable vector<monster> monsters. When the monster class is going to communicate with the world class, should I prefer using a callback function then or should I have a pointer to the world class inside the monster class?

  • Is there a way to extracting semantic informations from PDF? (converting PDF to pure XHTML)

    - by Eonil
    Hi. I'm finding a way to extract semantic structural informations (like title, heading, paragraph or lists) from PDF. Because I want to get a pure structural data from PDF. Finally, I want to create an pure XHTML from the PDF. With only structural informations. No design or layout. I know, PDF can be created without any structural information. I don't consider those PDFs. Only regularly well-structured PDFs are considered. I'm new to PDF. So I don't know it offers regular semantic structure or not. If it exists, it's library will offer it. So I want to know whether PDF spec has those information, and best way to get those information if exists.

  • TypeScript or JavaScript for noob web developer [closed]

    - by Phil Murray
    Following the recent release by Microsoft of TypeScript I was wondering if this is something that should be considered for a experienced WinForm and XAML developer looking to get into more web development. From reviewing a number of sites and videos online it appears that the type system for TypeScript makes more sense to me as a thick client developer than the dynamic type system in Javascript. I understand that Typescript compiles down to JavaScript but it appears that the learning curve is shallower due to the current tooling provided by Microsoft. What are your thoughts?

  • how do I get dual monitors to work properly in Ubuntu 11.10 on a Dell Latitude D630?

    - by wes cook
    I have spent a lot of time trying to get dual monitors to work on Ubuntu 11.10 on my Dell Latitude D630 (nVidia NVS 135m video card). - For starters, the System Displays settings app always only showed one unknown monitor, even though I had the external Acer monitor connected. - So I downloaded and installed the nVidia drivers. According to what I read I would need to only use the nVidia driver app (nVidia X Server Settings), so that's what I've done. (System Displays settings continued to only show a single monitor anyway). - nVidia settings app only showed on monitor until I changed the BIOS setting to use the onboard video for external monitor (not the dock video, which it was set to, even though I don't have a docking station). - The nVidia setting app now recognized both monitors. So, I setup the X Server display config as Separate X screen for both monitors. My laptop screen shows up as AUO 1440x900 and my external monitor as Acer E211H 1920x1080. - Everything seemed like it would work, but the external monitor was just a complete white screen. The external monitor was non-functional, even though sometimes it would show the background image - still nothing would show up over there. - So, I checked the Enable Xinerama box. - Now, after logging out and back in, the wallpaper extends to both screens but I get no taskbar at the bottom or top, no system menus, and I have to press the power button to restart or log off. - After experimenting with all the shells, the only one that shows the menus and taskbars when I log in is Gnome Classic. - This is pretty much the same symptoms as found here: How do I fix 11.10 GUI?. - So, I resign myself to the older shell. - Everything works fine until ... I unplug the external monitor ... this is a laptop after all. - Anyway, after doing some work on the road, I plug back in and I still see both screens and it's functional except, ... - Now, the laptop screen (with the taskbar and menu bar) has 4 black bars at the top that windows cannot cover. The top bar is the menu bar (with Applications, Places, the date and time and the system menu on the right). But the next 3 bars (the same height as the top menu bar) are empty and are just reducing the max size of windows on that screen. - See screenshot here: http://i39.tinypic.com/35d2kh1.png - So ... 1. How do I get rid of those extra 3 black bars? They're taking valuable screen space. 2. (less critical) How do I successfully use both screens in the Ubuntu or Ubuntu 2D shell?

  • Facebook dotnet app - not finding any user info

    - by Karen
    I am just starting to learn how to create a facebook app. I am using the MS dotnet libraries. Following this example and info: http://fbtutorial.qsh.eu/section1/fbml/step6.aspx I added some code in the default.aspx to print out the user name - but I am not getting any user information back. I understand that some user information is available even if the application is not authorized, such as name or user id. Example this code returns u=null: Facebook.Schema.user u = Master.Api.Users.GetInfo(); And this returns 0: this.Master.Api.Session.UserId Any suggestions as to why no information is getting returned? Thanks.

  • Retrieving Custom Attributes Using Reflection

    - by Scott Dorman
    The .NET Framework allows you to easily add metadata to your classes by using attributes. These attributes can be ones that the .NET Framework already provides, of which there are over 300, or you can create your own. Using reflection, the ways to retrieve the custom attributes of a type are: System.Reflection.MemberInfo public abstract object[] GetCustomAttributes(bool inherit); public abstract object[] GetCustomAttributes(Type attributeType, bool inherit); public abstract bool IsDefined(Type attributeType, bool inherit); System.Attribute public static Attribute[] GetCustomAttributes(MemberInfo member, bool inherit); public static bool IsDefined(MemberInfo element, Type attributeType, bool inherit); If you take the following simple class hierarchy: public abstract class BaseClass { private bool result;   [DefaultValue(false)] public virtual bool SimpleProperty { get { return this.result; } set { this.result = value; } } }   public class DerivedClass : BaseClass { public override bool SimpleProperty { get { return true; } set { base.SimpleProperty = value; } } } Given a PropertyInfo object (which is derived from MemberInfo, and represents a propery in reflection), you might expect that these methods would return the same result. Unfortunately, that isn’t the case. The MemberInfo methods strictly reflect the metadata definitions, ignoring the inherit parameter and not searching the inheritance chain when used with a PropertyInfo, EventInfo, or ParameterInfo object. It also returns all custom attribute instances, including those that don’t inherit from System.Attribute. The Attribute methods are closer to the implied behavior of the language (and probably closer to what you would naturally expect). They do respect the inherit parameter for PropertyInfo, EventInfo, and ParameterInfo objects and search the implied inheritance chain defined by the associated methods (in this case, the property accessors). These methods also only return custom attributes that inherit from System.Attribute. This is a fairly subtle difference that can produce very unexpected results if you aren’t careful. For example, to retrieve the custom  attributes defined on SimpleProperty, you could use code similar to this: PropertyInfo info = typeof(DerivedClass).GetProperty("SimpleProperty"); var attributeList1 = info.GetCustomAttributes(typeof(DefaultValueAttribute), true)); var attributeList2 = Attribute.GetCustomAttributes(info, typeof(DefaultValueAttribute), true));   The attributeList1 array will be empty while the attributeList2 array will contain the attribute instance, as expected.

  • Is event sourcing ready for prime time?

    - by Dakotah North
    Event Sourcing was popularized by LMAX as a means to provide speed, performance scalability, transparent persistence and transparent live mirroring. Before being rebranded as Event Sourcing, this type of architectural pattern was known as System Prevalence but yet I was never familiar with this pattern before the LMAX team went public. Has this pattern proved itself in numerous production systems and therefore even conservative individuals should feel empowered to embrace this pattern or is event sourcing / system prevalence an exotic pattern that is best left for the fearless?

  • A strong component keeps everything together

    - by Justin Paul-Oracle
    Most of the times you implement a WebCenter Content based system, you require some sort of customization. Sometimes these customizations need a Java class or two, or libraries (for example, the JavaMail API), or Database Objects (like new tables, views, indexes, etc). I have seen that libraries and Database Objects are usually put in place using manual steps. This means that the library jar files are copied to one of the common classes directory (set in the Content CLASSPATH variable) and/or the database scripts are executed manually. I have also seen people place the custom Java classes in the common classes directory. While this may seem like an easy solution, think about a scenario where you need to disable or uninstall the component or if you have to upgrade or migrate the system. You have to keep these manual steps documented and execute them every time you encounter the above scenarios. It is very common that some of these manual steps are missed when you have multiple teams and people working on the system. Here are a few points to ponder upon: Place all your custom Java classes within your component. Create a new directory, say ${COMPONENT_DIR}/classes, and place your code there. You can choose to bundle all your classes into a jar or you can place the entire class directory structure. Add a path entry to the Build Settings so that it is bundled with the component when you build it. You also need to update the Custom Class Path and the Custom Class Path Load Order under the Advanced Build Settings. This will ensure that the system CLASSPATH is updated to add this new directory. Create a new component for any new library that you want to add. Add the appropriate path entries to the Build Settings so that it is bundled with the component when you build it. You also need to update the Custom Class Path, Custom Class Path Load Order and/or the Custom Library Path under the Advanced Build Settings. Enter a comma separated list of features that this component will provide. When you create other components that will use the features exposed by this component, make sure that you specify a dependency to this library component by specifying the comma separated list of features in the Advanced Build Settings. The component wizard allows you to create custom install/uninstall Java code. The wizard will create a install filter class when you check the “Has Install” checkbox on the “Install/Uninstall Settings” tab. Consider using this filter class to create database objects when you install the component and drop the objects when you uninstall the component. If you do a lot of custom component development, consider creating a install/uninstall Java class, which can execute queries defined within the component. To sum up, whenever you write a new custom component, make sure that you bundle everything within the component.

  • When debugging on WinCE, how can I set Visual Studio to always load symbol files it knows about?

    - by tsellon
    I'm debugging a WinCE, C++ program in Visual Studio across an ActiveSync connection. Every time I start the process it fails to load symbol information. However, if I right click on the module and hit 'Load Symbols' it correctly locates the symbol information without any further prompting from me. Is there a way that I can set Visual Studio to either: (a) automatically load this symbol information, or (b) automatically break the process into the debugger once it's loaded (similar to what windbg does)? I'm guessing there's a setting somewhere, but I've yet to find it. Update: I forgot to mention in the original question that I'm not debugging with the instance of Visual Studio that created the exe.

  • ASP.NET Membership Password Hash -- .NET 3.5 to .NET 4 Upgrade Surprise!

    - by David Hoerster
    I'm in the process of evaluating how my team will upgrade our product from .NET 3.5 SP1 to .NET 4. I expected the upgrade to be pretty smooth with very few, if any, upgrade issues. To my delight, the upgrade wizard said that everything upgraded without a problem. I thought I was home free, until I decided to build and run the application. A big problem was staring me in the face -- I couldn't log on. Our product is using a custom ASP.NET Membership Provider, but essentially it's a modified SqlMembershipProvider with some additional properties. And my login was failing during the OnAuthenticate event handler of my ASP.NET Login control, right where it was calling my provider's ValidateUser method. After a little digging, it turns out that the password hash that the membership provider was using to compare against the stored password hash in the membership database tables was different. I compared the password hash from the .NET 4 code line, and it was a different generated hash than my .NET 3.5 code line. (Tip -- when upgrading, always keep a valid debug copy of your app handy in case you have to step through a lot of code.) So it was a strange situation, but at least I knew what the problem was. Now the question was, "Why was it happening?" Turns out that a breaking change in .NET 4 is that the default hash algorithm changed to SHA256. Hey, that's great -- stronger hashing algorithm. But what do I do with all the hashed passwords in my database that were created using SHA1? Well, you can make two quick changes to your app's web.config and everything will be OK. Basically, you need to override the default HashAlgorithmTypeproperty of your membership provider. Here are the two places to do that: 1. At the beginning of your element, add the following element: <system.web> <machineKey validation="SHA1" /> ... </system.web> 2. On your element under , add the following hashAlgorithmType attribute: <system.web> <membership defaultProvider="myMembership" hashAlgorithmType="SHA1"> ... </system.web> After that, you should be good to go! Hope this helps.
