  • Beginner C# image loading woes - NullReferenceException

    - by Seth Taddiken
    I keep getting a "NullReferenceExeption was unhandled" with "Object reference not set to an instance of an object." written under it.

  • Universities 2030: Learning from the Past to Anticipate the Future

    - by Mohit Phogat
    What will the landscape of international higher education look like a generation from now? What challenges and opportunities lie ahead for universities, especially “global” research universities? And what can university leaders do to prepare for the major social, economic, and political changes—both foreseen and unforeseen—that may be on the horizon? The nine essays in this collection proceed on the premise that one way to envision “the global university” of the future is to explore how earlier generations of university leaders prepared for “global” change—or at least responded to change—in the past. As the essays in this collection attest, many of the patterns associated with contemporary “globalization” or “internationalization” are not new; similar processes have been underway for a long time (some would say for centuries).[1] A comparative-historical look at universities’ responses to global change can help today’s higher-education leaders prepare for the future. Written by leading historians of higher education from around the world, these nine essays identify “key moments” in the internationalization of higher education: moments when universities and university leaders responded to new historical circumstances by reorienting their relationship with the broader world. Covering more than a century of change—from the late nineteenth century to the early twenty-first—they explore different approaches to internationalization across Europe, Asia, Australia, North America, and South America. Notably, while the choice of historical eras was left entirely open, the essays converged around four periods: the 1880s and the international extension of the “modern research university” model; the 1930s and universities’ attempts to cope with international financial and political crises; the 1960s and universities’ role in an emerging postcolonial international development apparatus; and the 2000s and the rise of neoliberal efforts to reform universities in the name of international economic “competitiveness.” Each of these four periods saw universities adopt new approaches to internationalization in response to major historical-structural changes, and each has clear parallels to today. Among the most important historical-structural challenges that universities confronted were: (1) fluctuating enrollments and funding resources associated with global economic booms and busts; (2) new modes of transportation and communication that facilitated mobility (among students, scholars, and knowledge itself); (3) increasing demands for applied science, technical expertise, and commercial innovation; and (4) ideological reconfigurations accompanying regime changes (e.g., from one internal regime to another, from colonialism to postcolonialism, from the cold war to globalized capitalism, etc.). Like universities today, universities in the past responded to major historical-structural changes by internationalizing: by joining forces across space to meet new expectations and solve problems on an ever-widening scale. Approaches to internationalization have typically built on prior cultural or institutional ties. In general, only when the benefits of existing ties had been exhausted did universities reach out to foreign (or less familiar) partners. As one might expect, this process of “reaching out” has stretched universities’ traditional cultural, political, and/or intellectual bonds and has invariably presented challenges, particularly when national priorities have differed—for example, with respect to curricular programs, governance structures, norms of academic freedom, etc. Strategies of university internationalization that either ignore or downplay cultural, political, or intellectual differences often fail, especially when the pursuit of new international connections is perceived to weaken national ties. If the essays in this collection agree on anything, they agree that approaches to internationalization that seem to “de-nationalize” the university usually do not succeed (at least not for long).

  • Image first loaded, then it isn't? (XNA)

    - by M0rgenstern
    I am very confused at the Moment. I have the following Class: (Just a part of the class): public class GUIWindow { #region Static Fields //The standard image for windows. public static IngameImage StandardBackgroundImage; #endregion } IngameImage is just one of my own classes, but actually it contains a Texture2D (and some other things). In another class I load a list of GUIButtons by deserializing a XML file. public static GUI Initializazion(string pXMLPath, ContentManager pConMan) { GUI myGUI = pConMan.Load<GUI>(pXMLPath); GUIWindow.StandardBackgroundImage = new IngameImage(pConMan.Load<Texture2D>(myGUI.WindowStandardBackgroundImagePath), Vector2.Zero, 1024, 600, 1, 0, Color.White, 1.0f, true, false, false); System.Console.WriteLine("Image loaded? " + (GUIWindow.StandardBackgroundImage.ImageStrip != null)); myGUI.Windows = pConMan.Load<List<GUIWindow>>(myGUI.GUIFormatXMLPath); System.Console.WriteLine("Windows loaded"); return myGUI; } Here this line: System.Console.WriteLine("Image loaded? " + (GUIWindow.StandardBackgroundImage.ImageStrip != null)); Prints "true". To load the GUIWindows I need an "empty" constructor, which looks like that: public GUIWindow() { Name = ""; Buttons = new List<Button>(); ImagePath = ""; System.Console.WriteLine("Image loaded? (In win) " + (GUIWindow.StandardBackgroundImage.ImageStrip != null)); //Image = new IngameImage(StandardBackgroundImage); //System.Console.WriteLine( //Image.IsActive = false; SelectedButton = null; IsActive = false; } As you can see, I commented lines out in the constructor. Because: Otherwise this would crash. Here the line System.Console.WriteLine("Image loaded? (In win) " + (GUIWindow.StandardBackgroundImage.ImageStrip != null)); Doesn't print anything, it just crashes with the following errormessage: Building content threw NullReferenceException: Object reference not set to an object instance. Why does this happen? Before the program wants to load the List, it prints "true". But in the constructor, so in the loading of the list it prints "false". Can anybody please tell me why this happens and how to fix it?

  • Can web applications running on IIS7 Windows Server 2008 R2 be forced to immediately detect changes to hosts file?

    - by Brenda Bell
    We have several web applications running on several load-balanced servers. We want to have our web applications communicate with each other without first traversing outside the load balancer. For example: http://appA.example.com is running on 192.0.2.1 and 192.0.2.2 http://appB.example.com is also running on 192.0.2.1 and 192.0.2.2 The load balancer's public IP address is 198.51.100.3 By default, when appA on 192.0.2.1 makes a call to a WCF service hosted in appB, the HTTP request is routed to 192.51.100.3; this establishes a new session and the load balancer will direct the call to either of the two servers We want the call to be routed to the instance of appB running on the same server so we add 192.0.2.1 appB.example.com to the hosts file on 192.0.2.1. This eventually works, but we either have to wait for the app pool to naturally recycle or do a manual reset before appA sees the new address. Is there any way to have the change automatically detected without having to recycle the app pool?

  • Determining cause of random latency/loading issues

    - by Sherwin Flight
    I'm not sure exactly what details to post in regards to my issue, because I'm not sure what is relevant. Prior to the end of September my websites all loaded quickly, in almost all cases. Loading time wasn't usually more than a few seconds. However, since the end of September I noticed a big increase in page loading times. In some cases pages were taking 30 seconds or more to load. I do have a remote monitoring service monitoring some of the sites as well, and the image below shows the response times over the past month. The response times shown at the beginning of this graph were what the usual response times were prior to this issue occurring. You can see that there has been a significant increase in response times from the beginning to the end of this graph. The thing is, the problem is not happening 100% of the time. If I click through the site, or even just keep refreshing the page, about 25% of the time the pages load quickly, the remaining 75% of the time they load slowly. Sometimes the pages take so long to load that they time out, and don't load at all. I have contacted my hosting provider, and they said things at their end was fine. I don't believe the problem is my home internet provider, because all other websites load without a problem. The server is located in Texas, USA. This also raises another interesting point. My remote monitor checks my site from two locations, California, USA, and London, England. As you can see in the chart below the response time is actually shorter when checked from London, which doesn't seem to make sense, since the server is physically closer to the California monitoring location. I would have expected the London monitoring location to have higher response times since they are physically farther away. I should also point out that in some traceroute test I've done it seem like the first connection to the server seems to take the longest, then after that the rest of the page loads quickly. Below is a little chart showing the times for the first connection to the server. So, what could be causing this problem, and what steps can I take to resolve it or at least narrow down the problem? Sending the request to the server was very quick, and receiving the reply back seems pretty quick, but the WAIT time is really long. So it connects, sends the request, but then waits close to 30 seconds before it starts receiving data back. I am also aware that there are things I can do to speed up page loading times, like reducing the number of css/js files used on a page, compressing images, etc. This is not really what the source of the problem is though, because nothing has really changed on the site since before the problem started, and other sites on the same server are loading slowly as well. Any help or advice is much appreciated.

  • Apt Configuration problem

    - by Paul
    I am trying to load v11.04 onto my HP desktop hard drive using a USB drive. I used the same USB drive to load the system on my Dell netbook and it loaded successfully. But trying to load on the desktop I get the error " Apt configuration problem. An attempt to configure apt to install additional packages from the CD failed" The installer then crashes. I have nothing in the CD drive. I can boot the system from the USB drive and it works fine. I have tried all options on the load with the same crash each time. I baffled as I successfully loaded my netbook with the same USB with no problems.

  • Is it possible to increase the levels of abstraction I can hold in my head/reason about at once? How would I go about this? [closed]

    - by invaliduser
    I'd like to be able to read through fifteen pages of assembly code and know what it does. I'd like to be able to write programs that write programs that write programs that write programs. We've made a lot of strides in taking load off our brains by with good tools (Chrome dev mode/Firebug for web stuff, REPL's for many languages, IDEs), but I'd like my brain to be able to handle a bigger load, as opposed to paring the load down with tools.

  • Loading assets in Monogame

    - by Matebu
    I'm creating a MonoGame application on Visual Studio 2012, yet when trying to load a texture I get the following problem: Could not load Menu/btnPlay asset! I have set content directory: Content.RootDirectory = "Assets"; Also the file btnPlay.png has properties set: Build Action: Content and Copy to Output directory: Copy if newer. My constructor and LoadContent functions are totally empty, but have a look yourself: public WizardGame() { Window.Title = "Just another Wizard game"; _graphics = new GraphicsDeviceManager(this); Content.RootDirectory = "Assets"; } protected override void LoadContent() { // Create a new SpriteBatch, which can be used to draw textures. _spriteBatch = new SpriteBatch(GraphicsDevice); Texture2D texture = Content.Load<Texture2D>("Menu/btnPlay"); _graphics.IsFullScreen = true; _graphics.ApplyChanges(); } How do I properly load a texture?

  • TOP CPU usage for whole system

    - by heike
    I am using a machine that has using cat /proc/cpuinfo | grep processor | wc -l returning 8 I am trying to load the server using a load generator that I wrote, and capture the behaviour of TOP command for idle (as the software that is tested on server runs on ROOT). Doing the load as an increasing step function, I capture the idle state every second, and see the result. Strange thing is that when I increase the load every 1 minute, the idle state is infact increasing (??). This honestly does not make sense .. I thought with more load, the idle state will decrease, and the cpu usage will increase. Is there any reasonable explanation for this behaviour, maybe for the server utilization itself? Thanks for any feedback -- ok, no idea for the down vote. but I try to find this behaviour a lot, can not find any reasonable things to explain this ..

  • (Phaser) Preload Future States in Create?

    - by Brian
    I'm a first time user of Phaser, been trying to make a simple point and click type game. I'm trying to keep things very modular, so I'm defining a list of levels (states) in a JSON, and then every level has its own JSON containing the objects within that level. However, I'm encountering an issue in that, when changing states, I get a black flash while the assets for the next state load (this happens whether I iterate through the JSON list or define everything manually). From what I've read, all sprites should be loaded in the preload stage, however, by doing this I'm causing that tiny but noticeable black pause. I know one way would be to simply load every asset at the start of the game, but that seems incredibly inefficient (wouldn't that fill up the memory immensely?). I would rather load a state's assets from the "parent" state. However, in my quick test (which maybe I did wrong) it seems that game.load doesn't work properly if done within the create stage? What is the best approach to doing this?

  • PHP: Writing non-english characters to XML - encoding problem

    - by Dean
    Hello, I wrote a small PHP script to edit the site news XML file. I used DOM to manipulate the XML (Loading, writing, editing). It works fine when writing English characters, but when non-English characters are written, PHP throws an error when trying to load the file.

  • Property being immediately reset by ApplicationSetting Property Binding

    - by Slider345
    I have a .net 2.0 windows application written in c#, which currently uses several project settings to store user configurations. The forms in the application are made up of lots of user controls, each of which have properties that need to be set to these project settings. Right now these settings are manually assigned to the user control properties. I was hoping to simplify the code by replacing the manual implementation with ApplicationSettings Property Bindings. However, my first property is not behaving properly at all. The setting is an integer, used to record a port number typed into a text box. The setting is bound to an integer property on a user control, and that property sets the Text property on a TextBox control. When I type a new value into the textbox at runtime, as soon as the textbox loses focus, it is immediately replaced by the original value. A breakpoint on the property shows that it is immediately setting the property to the setting from the properties collection after I set it. Can anyone see what I'm doing wrong? Here's some code: The setting: [global::System.Configuration.UserScopedSettingAttribute()] [global::System.Diagnostics.DebuggerNonUserCodeAttribute()] [global::System.Configuration.DefaultSettingValueAttribute("1000")] public int Port { get{ return ((int)(this["Port"])); } set{ this["Port"] = value; } } The binding: this.ctrlNetworkConfig.DataBindings.Add(new System.Windows.Forms.Binding("PortNumber", global::TestProject.Properties.Settings.Default, "Port", true, System.Windows.Forms.DataSourceUpdateMode.OnPropertyChanged)); this.ctrlNetworkConfig.PortNumber = global::TestProject.Properties.Settings.Default.Port; And lastly, the property on the user control: public int PortNumber { get{ int port; if(int.TryParse(this.txtPortNumber.Text, out port)) return port; else return 0; } set{ txtPortNumber.Text = value.ToString(); } } Any thoughts? Thanks in advance for your help. EDIT: Sorry about the formatting, trying to correct.

  • Building ARM assembler vorbis decoder lib 'Tremolo' for iPhone

Googling for the ARM instruction set, the above instructions look valid to me. I've tried toggling thumb support, and building for just armv7 instead of armv6, but neither helped.

  • Why is ExecuteFunction method only available through base.ExecuteFunction in a child class of Object

    - by Matt
    I'm trying to call ObjectContext.ExecuteFunction from my objectcontext object in the repository of my site. The repository is generic, so all I have is an ObjectContext object, rather than one that actually represents my specific one from the Entity Framework. Here's an example of code that was generated that uses the ExecuteFunction method: [global::System.CodeDom.Compiler.GeneratedCode("System.Data.Entity.Design.EntityClassGenerator", "4.0.0.0")] public global::System.Data.Objects.ObjectResult<ArtistSearchVariation> FindSearchVariation(string source) { global::System.Data.Objects.ObjectParameter sourceParameter; if ((source != null)) { sourceParameter = new global::System.Data.Objects.ObjectParameter("Source", source); } else { sourceParameter = new global::System.Data.Objects.ObjectParameter("Source", typeof(string)); } return base.ExecuteFunction<ArtistSearchVariation>("FindSearchVariation", sourceParameter); } But what I would like to do is something like this... public class Repository<E, C> : IRepository<E, C>, IDisposable where E : EntityObject where C : ObjectContext { private readonly C _ctx; // ... public ObjectResult<E> ExecuteFunction(string functionName, params[]) { // Create object parameters return _ctx.ExecuteFunction<E>(functionName, /* parameters */) } } Anyone know why I have to call ExecuteFunction from base instead of _ctx? Also, is there any way to do something like I've written out? I would really like to keep my repository generic, but with having to execute stored procedures it's looking more and more difficult... Thanks, Matt

  • Globals are bad! But should I use them in this context?

    - by Matt
    Would setting the $link to my database be one thing that I should use a GLOBAL scope for? In my setting of (lots of functions)...it seems as though having only one variable that is in the global scope would be wise. I am currently using the functions to transfer it back and forth so that way I do not have it in the global scope. But it is a bit of a hindrance to my script. Please advise.

  • Loops on a Matlab program

    - by lebland-matlab
    I have 3 sets of 10 vectors each, and I want to take 2 vectors from the first set , 2 vectors from the second set and 3 vectors from the third set . My goal is to make a loop to implement the following program, knowing that after each calculation, the result shall be saved in a new file. My problem is that I can not handle the indices included in the strings. I try to use multiple loops to scan the 3 sets in the order of indices. loops should contain the following program clc; clear all; load('C:\Users\Documents\MATLAB\myFile\matrice_F.mat'); load('C:\Users\Documents\MATLAB\myFile\matrice_G.mat'); F = m_F; G = m_G; load('C:\Users\Documents\MATLAB\myFile\matrice_J.mat'); load('C:\Users\Documents\MATLAB\myFile\matrice_K.mat'); J = m_J; K = m_K; load('C:\Users\Documents\MATLAB\myFile\matrice_N.mat'); load('C:\Users\Documents\MATLAB\myFile\matrice_O.mat'); load('C:\Users\Documents\MATLAB\myFile\matrice_P.mat'); N = m_N ; O = m_O; P = m_P; [A,B,C,D,E] = myFun(F,G,J,K,N,O,P); file_name = 'matrice_final.mat'; save(file_name,'A','B','C','D','E');

  • Saving/Associating slider values with a pop-up menu

    - by James
    Hi, Following on from a question I posted yesterday about GUIs, I have another problem I've been working with. This question related to calculating the bending moment on a beam under different loading conditions. On the GUI I have developed so far, I have a number of sliders (which now work properly) and a pop-up menu which defines the load case. I would like to be able to select the load case from the pop-up menu and position the loads as appropriate, in order to define each load case in turn. The output that I need is an array defining the load case number (the rows) and a number of loading parameters (the itensity and position of the loads, which are controlled by the sliders). The problem I am having is that I can produce this array (of the size I need) and define the loading for one load case (by selecting the pop-up menu) using the sliders, but when I change the popup menu again, the array only keeps the loading for the load case selected by the pop-up menu. Can anyone suggest an approach I can take with (specifically to store the variables from each load case) or an example that illustrates a similar solution to the problem? The probem may be a bit vague, so please let me know if anything needs clearing up. Many Thanks, James

  • How do I store an array of a particular type into my settings file?

    - by joebeazelman
    For some reason, I can't seem to store an array of my class into the settings. Here's the code: var newLink = new Link(); Properties.Settings.Default.Links = new ArrayList(); Properties.Settings.Default.Links.Add(newLink); Properties.Settings.Default.Save(); In my Settings.Designer.cs I specified the field to be an array list: [global::System.Configuration.UserScopedSettingAttribute()] [global::System.Diagnostics.DebuggerNonUserCodeAttribute()] public global::System.Collections.ArrayList Links { get { return ((global::System.Collections.ArrayList)(this["Links"])); } set { this["Links"] = value; } } For some reason, it won't save any of the data even though the Link class is serializable and I've tested it.

  • How can I make this Matlab program possible?

    - by lebland-matlab
    I do not know how to combine the indices with the characters, Could you help me to make this program possible: clc; clear all; set1={F,G,FF,GG,X,Y,XX,L,BH,JK}; %set of name vectors set2={J,K,HG,UY,TR,BC,XW,IOP,ES,QA}; %set of name vectors set3={AJ,RK,DS,TU,WS,ZZE,ZXW,TYP,ZAA,QWW}; %set of name vectors for i=1:1:9 load('C:\Users\Documents\MATLAB\myFile\matrice_'set1(i)'.mat'); load('C:\Users\Documents\MATLAB\myFile\matrice_'set1(i+1)'.mat'); 'set1(i)' = m_'set1(i)'; 'set1(i+1)' = m_'set1(i+1)'; for j=1:1:9 load('C:\Users\Documents\MATLAB\myFile\matrice_'set2(j)'.mat'); load('C:\Users\Documents\MATLAB\myFile\matrice_'set2(j+1)'.mat'); 'set2(j)' = m_'set2(j)'; 'set2(j+1)' = m_'set2(j+1)'; for k=1:1:8 load('C:\Users\Documents\MATLAB\myFile\matrice_'set3(k)'.mat'); load('C:\Users\Documents\MATLAB\myFile\matrice_'set3(k+1)'.mat'); load('C:\Users\Documents\MATLAB\myFile\matrice_'set3(k+2)'.mat'); 'set3(k)' = m_'set3(k)' ; 'set3(k+1)' = m_'set3(k+1)'; 'set3(k+2)' = m_'set3(k+2)'; [Result1'index',Result2'index',Result3'index',Result4'index',Result5'index'] = myFun('set1(i)','set1(i+1)','set2(j)','set2(j+1)','set3(k)','set3(k+1)','set3(k+2)'); %% 9x9x8=648 index=1,2,...,648 file_name = 'matrice_final'index'.mat'; save(file_name,'Result1'index'','Result2'index'','Result3'index'','Result4'index'','Result5'index''); clear 'set3(k)' 'set3(k+1)' 'set3(k+2)' end clear 'set2(j)' 'set2(j+1)' end clear 'set1(i)' 'set1(i+1)' end

  • Maintain order of messages via proxies to app servers

    - by David Turner
    Hi, I am receiving messages from a 3rd party via a http post, and it is important that the order the messages hit our infrastructure is maintained through the load balancers and proxies until it hits our application server. Quick Diagram. (proxies in place due to security requirements.) [ACE load balancer] - [2 proxies] - [Application Servers] or maybe [ACE load balancer] - [2 proxies] - [ACE load balancer] - [Application Servers] My idea was that I would setup the load balancers in active-passive mode, to force all messages to use one proxy, and then both the proxies would hit a second load balancer that would be configured in active passive to hit one application server. Whilst the above is not ideal, it does give me resilience, and once the message is in my app servers, I enter a stateless world, and load balance across both nodes of my cluster. However, I am concerned that even a single proxy could send messages out of order, perhaps if 2 messages are recived very close together, message 2 might get processed faster than message 1. Is this possible? Likely? Is there a simple open source proxy (MOD_PROXY?) that can be easily configured to just pass messages through it, and to guarantee to send the messages through in the order they are received. If so which, and finally links to how I should configure it would be great. In fact any links to articles around avoiding "out of order" messages using hardware would be gratefully received. Thanks, ps for those that are interested, the app is a java spring integration application currently on a appliation server.
