• Thread problem updating Windows Forms control in XNA C#

  - by Luis

  I'm development a network card game, and for now i've two players connected but there is a problem with one of them, this one can't do anything on the game. Looks that screen was blocked. I'm think that is because a code i used before. That code is: if (InvokeRequired) { this.Invoke(new MethodInvoker(delegate { ... })); return; } The code above is surrounding code to changing Button values, make connection with server and create game window. Without this code a warning is shown. InvalidOperationException was unhandled Cross-thread operation not valid: Control 'startGameButton' accessed from a thread other than the thread it was created on.

• SQL SERVER – Retrieving Random Rows from Table Using NEWID()

  - by pinaldave

  I have previously written about how to get random rows from SQL Server. SQL SERVER – Generate A Single Random Number for Range of Rows of Any Table – Very interesting Question from Reader SQL SERVER – Random Number Generator Script – SQL Query However, I have not blogged about following trick before. Let me share the trick here as well. You can generate random scripts using following methods as well. USE AdventureWorks2012 GO -- Method 1 SELECT TOP 100 * FROM Sales.SalesOrderDetail ORDER BY NEWID() GO -- Method 2 SELECT TOP 100 * FROM Sales.SalesOrderDetail ORDER BY CHECKSUM(NEWID()) GO You will notice that using NEWID() in the ORDER BY will return random rows in the result set. How many of you knew this trick? You can run above script multiple times and it will give random rows every single time.

• After suspend, my monitor wont turn back on

  - by David

  I set my pc to suspend after 5 minutes of inactivity, when I return to my computer I mash a couple of keys and the pc turns back on and the drives start spinning etc etc, but I get no signal to either of my monitors. My peripherals are powered as the num/caps lock lights turn on and off. I should add I have two monitors, I have the same problem on both. As I am writing the last line from my previous paragraph keeps disappearing. I press control z and it comes back but kinda weird. Thanks in advance for any help :)

• Impact of variable-length loops on GPU shaders

  - by Will

  Its popular to render procedural content inside the GPU e.g. in the demoscene (drawing a single quad to fill the screen and letting the GPU compute the pixels). Ray marching is popular: This means the GPU is executing some unknown number of loop iterations per pixel (although you can have an upper bound like maxIterations). How does having a variable-length loop affect shader performance? Imagine the simple ray-marching psuedocode: t = 0.f; while(t < maxDist) { p = rayStart + rayDir * t; d = DistanceFunc(p); t += d; if(d < epsilon) { ... emit p return; } } How are the various mainstream GPU families (Nvidia, ATI, PowerVR, Mali, Intel, etc) affected? Vertex shaders, but particularly fragment shaders? How can it be optimised?

• How to write functionally in a web framework

  - by Kevin Burke

  I love Rich Hickey, Clojure and Haskell and I get it when he talks about functions and the unreliability of side-effecting code. However I work in an environment where nearly all the functions I write have to read from the database, write to the database, make HTTP requests, decrement a user's balance, modify a frontend HTML component based on a click action, return different results based on the URI or the POST body. We also use PHP for the frontend, which is littered with functions like parse_str(), which modifies an object in place. All of these are side-effecting to one degree or another. Given these constraints and the side-effecting nature of the logic I'm coding, what can I do to make my code more reliable and function-able?

• BizTalk 2009 - Service Instances: Last 100

  - by StuartBrierley

  Having previously talked about the lack of the traditional HAT in BizTalk 2009, the question then becomes how do you replicate some of the functionality that was previsouly relied on? I have already covered the Last 100 Messages Received, the Last 100 Messages Sent, and the Last 50 Suspended Messages queries so what about service instances? The BizTalk 2009 Group Hub allows you to search for suspended service instances and also running service instances, but not the two together. In BizTalk 2004 we had a query in HAT to return the last 100 service instances.  Lets create a direct replacement in the BizTalk 2009 Hatless environment. Basically we are creating a query to search for the last one hundred tracked service instances:

• Obtain rectangle indicating 2D world space camera can see

  - by Gareth

  I have a 2D tile based game in XNA, with a moveable camera that can scroll around and zoom. I'm trying to obtain a rectangle which indicates the area, in world space, that my camera is looking at, so I can render anything this rectangle intersects with (currently, everything is rendered). So, I'm drawing the world like this: _SpriteBatch.Begin( SpriteSortMode.FrontToBack, null, SamplerState.PointClamp, // Don't smooth null, null, null, _Camera.GetTransformation()); The GetTransformation() method on my Camera object does this: public Matrix GetTransformation() { _transform = Matrix.CreateTranslation(new Vector3(-_pos.X, -_pos.Y, 0)) * Matrix.CreateRotationZ(Rotation) * Matrix.CreateScale(new Vector3(Zoom, Zoom, 1)) * Matrix.CreateTranslation(new Vector3(_viewportWidth * 0.5f, _viewportHeight * 0.5f, 0)); return _transform; } The camera properties in the method above should be self explanatory. How can I get a rectangle indicating what the camera is looking at in world space?

• Disable outbound links without letting others know that

  - by tadoman

  Is there a way I can tell google not to follow external links ( pointing to other sites) without letting other know. I know you can disable outbound links by putting rel=nofollow or something in robots.txt. But that's something others can see as well. I'm just wondering if there's a way to tell google not to follow those links without letting others know that... like a setting in webmaster tools or something similar ( there's definetly one way. I could set an exception in my conf file for my server to check the user agent to be "googlebot" and then serve a different version of robots.txt. So that when a different user would check that link it would return a different robots.txt thant the one served to googlebot. However I'm not too sure google would be too happy about this) Thank you

• Workaround the flip queue (AKA pre-rendered frames) in OpenGL?

  - by user41500

  It appears that some drivers implement a "flip queue" such that, even with vsync enabled, the first few calls to swap buffers return immediately (queuing those frames for later use). It is only after this queue is filled that buffer swaps will block to synchronize with vblank. This behavior is detrimental to my application. It creates latency. Does anyone know of a way to disable it or a workaround for dealing with it? The OpenGL Wiki on Swap Interval suggests a call to glFinish after the swap but I've had no such luck with that trick.

• What is the best way to find a python google app engine coach?

  - by David Haddad

  i'm a software engineer and have been building Google App Engine apps with Python for about a year. I have a pretty good familiarity with the main concepts: web app framework, modeling, queues, memcache, django templates, etc. Where I think I'm lacking is in methodology. Architecting the app, using git for versioning, designing an writing unit tests. I'm totally convinced to incorporate these practices in my development style, and have started reading up on them. However I've learned that I'm a much faster learner when I have someone experienced to ask questions to and interact with. IRC channels and forums like stack overflow are great. But sometimes you want something more dynamic that produces results faster. So my question is how can a person find an experienced engineer that is familiar with the technologies he uses and that is willing to give them a couple of hours of Skype coaching sessions per week in return for an hourly fee...

• Saving an interface instance into a Bundle

  - by user22241

  All I've have an interface that allows me to switch between different scenes in my Android game. When the home key is pressed, I am saving all of my states (score, sprite positions etc) into a Bundle. When re-launching, I am restoring all my states and all is OK - however, I can't figure out how to save my 'Scene', thus when I return, it always starts at the default screen which is the 'Main Menu'. How would I go about saving my 'Scene' (into a Bundle)? Code import android.view.MotionEvent; public interface Scene{ void render(); void updateLogic(); boolean onTouchEvent(MotionEvent event); } I assume the interface is the relevant piece of code which is why I've posted that snippet. I set my scene like so: ('options' is an object of my Options class which extends MainMenu (Another custom class) which, in turn implements the interface 'Scene') SceneManager.getInstance().setCurrentScene(options); //Current scene is optionscreen

• Unity3D Android - Move your character to a specific x position

  - by user3666251

  Im making a new game for android and I wanted to move my character (which is a cube for now) to a specific x location (on top of a flying floor/ground thingy) but I've been having some troubles with it.I've been using this script : var jumpSpeed: float = 3.5; var distToGround: float; function Start(){ // get the distance to ground distToGround = collider.bounds.extents.y; } function IsGrounded(): boolean { return Physics.Raycast(transform.position, -Vector3.up, distToGround + 0.1); } function Update () { // Move the object to the right relative to the camera 1 unit/second. transform.Translate(Vector3.forward * Time.deltaTime); if (Input.anyKeyDown && IsGrounded()){ rigidbody.velocity.x = jumpSpeed; } } And this is the result (which is not what I want) : https://www.youtube.com/watch?v=Fj8B6eI4dbE&feature=youtu.be Anyone has any idea how to do this ? Im new in unity and scripting.Im using java btw. Ty.

• C# replacing out parameters with struct

  - by Jonathan

  I'm encountering a lot of methods in my project that have a bunch of out parameters embedded in them and its making it cumbersome to call the methods as I have to start declaring the variables before calling the methods. As such, I would like to refactor the code to return a struct instead and was wondering if this is a good idea. One of the examples from an interface: void CalculateFinancialReturnTotals(FinancialReturn fr, out decimal expenses, out decimal revenue, out decimal levyA, out decimal levyB, out decimal profit, out decimal turnover, out string message) and if I was to refactor that, i would be putting all the out parameters in the struct such that the method signature is much simpler as below. [structName] CalculateFinancialReturnTotals(FinancialReturn fr); Please advise.

• Sharing unique links on social media vs SEO

  - by MJWadmin

  We're currently implementing a voucher system on our site which will allow our users to obtain a 25+% discount on certain products, provided they donate 10% of the purchase price to charity. We will offer the ability to share the discounts via social media in return for larger discounts to the sharer for each person who clicks through the link and buys an item. I understand that social links have SEO benifits, but this appears to be based on lots of people sharing the same link. If our voucher users share a unique link i.e. http://ourdomain.com/sipsfesdf rather than a fixed link http://ourdomain.com/product-name will we still receive the same benifts? Should we instead share something like http://ourdomain.com/product-name/sipsfesdf Thanks in advance.

• What is your most unusual javascript concept you've ever seen ?

  - by Cybrix

  Hi, I've learned javascript at school but since I'm working with it and study about it every day, I've found very particular aspect of javascript that I didn't know about. Which at first, was very hard to understand for me and finally, I found it very usefull and easy to implement. And in the final, it gives to my code some kind of "beauty". An example I've once seen: function getter( input ) { result = { foo1 : 'bar1', foo2 : 'bar2', foo3 : 'bar3' }[input] || input || "default"; return result; } Do you guys have other examples of particular use you make of Javascript ? Thank you PS: I use the term particular use because it might be unusual for any Javascript beginner. I believe this question is most likely to belong to the community wiki.

• How can I gain access to a player instance in a Minecraft mod?

  - by Andrew Graber

  I'm creating Minecraft mod with a pickaxe that takes away experience when you break a block. The method for taking away experience from a player is addExperience on EntityPlayer, so I need to get an instance of EntityPlayer for the player using my pickaxe when the pickaxe breaks a block, so that I can remove the appropriate amount of experience. My pickaxe class currently looks like this: public class ExperiencePickaxe extends ItemPickaxe { public ExperiencePickaxe(int ItemID, EnumToolMaterial material){ super(ItemID, material); } public boolean onBlockDestroyed(ItemStack par1ItemStack, World par2World, int par3, int par4, int par5, int par6, EntityLiving par7EntityLiving) { if ((double)Block.blocksList[par3].getBlockHardness(par2World, par4, par5, par6) != 0.0D) { EntityPlayer e = new EntityPlayer(); // create an instance e.addExperience(-1); } return true; } } Obviously, I cannot actually create a new EntityPlayer since it is an abstract class. How can I get access to the player using my pickaxe?

• ejabberd won't look at my host_config option

  - by John

  I'm new with ejabberd. What I want is to have a host myhost.domain.com which has an ldap authentication method. This all works fine if i modify the global options in AUTHENTICATION section in my ejabberd.cfg file. I am able to create two clients( defined in my LDAP directory ), and comunicate between them. Like i said, this works fine. But by aplying this authentication method globaly, it means that every hostname that i declare must use that. So i'm looking at {host_config, "myhost.domain.com" ...} But somehow i can't get ejabberd to look at that configuration, it just skips it. If i declare it like: {xhost_config, ...}, than in my ejabberd.log file i get a bad return error( so it knows that the configuration is there, but it won't look at it). Any suggestions? Thanks.

• Code refactoring with Visual Studio 2010 Part-4

  - by Jalpesh P. Vadgama

  I have been writing few post with code refactoring features in Visual Studio 2010. This post also will be part of series and this post will be last of the series. In this post I am going explain two features 1) Encapsulate Field and 2) Extract Interface. Let’s explore both features in details. Encapsulate Field: This is a nice code refactoring feature provides by Visual Studio 2010. With help of this feature we can create properties from the existing private field of the class. Let’s take a simple example of Customer Class. In that I there are two private field called firstName and lastName. Below is the code for the class. public class Customer { private string firstName; private string lastName; public string Address { get; set; } public string City { get; set; } } Now lets encapsulate first field firstName with Encapsulate feature. So first select that field and goto refactor menu in Visual Studio 2010 and click on Encapsulate Field. Once you click that a dialog box will appear like following. Now once you click OK a preview dialog box will open as we have selected preview reference changes. I think its a good options to check that option to preview code that is being changed by IDE itself. Dialog will look like following. Once you click apply it create a new property called FirstName. Same way I have done for the lastName and now my customer class code look like following. public class Customer { private string firstName; public string FirstName { get { return firstName; } set { firstName = value; } } private string lastName; public string LastName { get { return lastName; } set { lastName = value; } } public string Address { get; set; } public string City { get; set; } } So you can see that its very easy to create properties with existing fields and you don’t have to change anything there in code it will change all the stuff itself. Extract Interface: When you are writing software prototype and You don’t know the future implementation of that then its a good practice to use interface there. I am going to explain here that How we can extract interface from the existing code without writing a single line of code with the help of code refactoring feature of Visual Studio 2010. For that I have create a Simple Repository class called CustomerRepository with three methods like following. public class CustomerRespository { public void Add() { // Some code to add customer } public void Update() { //some code to update customer } public void Delete() { //some code delete customer } } In above class there are three method Add,Update and Delete where we are going to implement some code for each one. Now I want to create a interface which I can use for my other entities in project. So let’s create a interface from the above class with the help of Visual Studio 2010. So first select class and goto refactor menu and click Extract Interface. It will open up dialog box like following. Here I have selected all the method for interface and Once I click OK then it will create a new file called ICustomerRespository where it has created a interface. Just like following. Here is a code for that interface. using System; namespace CodeRefractoring { interface ICustomerRespository { void Add(); void Delete(); void Update(); } } Now let's see the code for the our class. It will also changed like following to implement the interface. public class CustomerRespository : ICustomerRespository { public void Add() { // Some code to add customer } public void Update() { //some code to update customer } public void Delete() { //some code delete customer } } Isn't that great we have created a interface and implemented it without writing a single line of code. Hope you liked it. Stay tuned for more.. Till that Happy Programming.

• Default program startup display

  - by Tony Martin

  I have a dual display setup and would like to be able to set which display a piece of software starts on. Most software seems to return to the last display but Stellarium always starts in the primary display. Does Linux have a way of forcing the startup display or is it something the individual program has to manage? Thanks. EDIT And with no changes on my part Stellarium is behaving nicely and remembering which screen it was on. Still nice to know if there is a way of forcing this.

• setPosition of Sprite onUpdate in AndEngine

  - by SSH This

  I am trying to get a "highlighter" circle to follow around a sprite, but I am having trouble, I thought I could use the onUpdate method that's available to me in SequenceEntityModifier but it's not working for me. Here is my code: // make sequence mod with move modifier SequenceEntityModifier modifier = new SequenceEntityModifier(myMovemod) { @Override protected void onModifierFinished(IEntity pItem) { // animation finished super.onModifierFinished(pItem); } public float onUpdate(float pSecondsElapsed, IEntity pItem) { highlighter.setPosition(player2.getX() - highlighterOffset, player2.getY() - highlighterOffset); return pSecondsElapsed; } }; When onUpdate is completely commented out, the sprite moves like I want it to, everything is ok. When I put the onUpdate in, the sprite doesn't move at all. I have a feeling that I am overriding the original onUpdate's actions? Am I going about this the wrong way? I am new to Java, so please feel free to advise if this isn't going to work. UPDATE: The player2 is the sprite that I'm trying to get the highlighter to follow.

• MVC, when to separate controllers?

  - by Rodolfo

  I'm starting with MVC and have a newbie question. What would be the logic criteria to define what a controller should encompass? For example, say a website has a 'help' section. In there, there are several options like: 'about us', 'return instructions', 'contact us', 'employment opportunities'. Each would then be accessed like 'mysite.com/help/aboutus', 'mysite.com/help/returns', 'mysite.com/help/contactus', etc. My question is, should I have a 'help' controller that has 'about us', 'returns', 'contact us', 'employment' as actions with their respective view, or should each of those be a different controller-action-view set? What should be the line of reasoning to determine when to separate controllers?

• Returning Images from ASP.NET Web API

  - by bipinjoshi

  Sometimes you need to save and retrieve image data in SQL Server as a part of Web API functionality. A common approach is to save images as physical image files on the web server and then store the image URL in a SQL Server database. However, at times you need to store image data directly into a SQL Server database rather than the image URL. While dealing with the later scenario you need to read images from a database and then return this image data from your Web API. This article shows the steps involved in this process. http://www.bipinjoshi.net/articles/4b9922c3-0982-4e8f-812c-488ff4dbd507.aspx
