    Hi, I have recently signed up for a travel affiliate program and I create a module with search fields to search in the affiliate program. What I need is a component with ..., so when I make a search the search results to shows in the ... in the component. In this way I can chose which other module to show or not with the search results. Could someone tell me how to do it or tell me a similar module/component. I would be grateful if you provide me with an answer or a solution of any kind! Thank you in advance!

  • How to get Augmented Reality: A Practical Guide examples working?

    - by Glen
    I recently bought the book: Augmented Reality: A Practical Guide (http://pragprog.com/titles/cfar/augmented-reality). It has example code that it says runs on Windows, MacOS and Linux. But I can't get the binaries to run. Has anyone got this book and got the binaries to run on ubuntu? I also can't figure out how to compile the examples in Ubuntu. How would I do this? Here is what it says to do: Compiling for Linux Refreshingly, there are no changes required to get the programs in this chapter to compile for Linux, but as with Windows, you’ll first have to find your GL and GLUT files. This may mean you’ll have to download the correct version of GLUT for your machine. You need to link in the GL, GLU, and GLUT libraries and provide a path to the GLUT header file and the files it includes. See whether there is a glut.h file in the /usr/include/GL directory; otherwise, look elsewhere for it—you could use the command find / -name "glut.h" to search your entire machine, or you could use the locate command (locate glut.h). You may need to customize the paths, but here is an example of the compile command: gcc -o opengl_template opengl_template.cpp -I /usr/include/GL -I /usr/include -lGL -lGLU -lglut gcc is a C/C++ compiler that should be present on your Linux or Unix machine. The -I /usr/include/GL command-line argument tells gcc to look in /usr/include/GL for the include files. In this case, you’ll find glut.h and what it includes. When linking in libraries with gcc, you use the -lX switch—where X is the name of your library and there is a correspond- ing libX.a file somewhere in your path. For this example, you want to link in the library files libGL.a, libGLU.a, and libglut.a, so you will use the gcc arguments -lGL -lGLU -lglut. These three files are found in the default directory /usr/lib/, so you don’t need to specify their location as you did with glut.h. If you did need to specify the library path, you would add -L to the path. To run your compiled program, type ./opengl_template or, if the current directory is in your shell’s paths, just opengl_template. When working in Linux, it’s important to know that you may need to keep your texture files to a maximum of 256 by 256 pixels or find the settings in your system to raise this limit. Often an OpenGL program will work in Windows but produce a blank white texture in Linux until the texture size is reduced. The above instructions make no sense to me. Do I have to use gcc to compile or can I use eclipse? If I use either eclipse or gcc what do I need to do to compile and run the program?

  • Achieving C# "readonly" behavior in C++

    - by Tommy Fisk
    Hi guys, this is my first question on stack overflow, so be gentle. Let me first explain the exact behavior I would like to see. If you are familiar with C# then you know that declaring a variable as "readonly" allows a programmer to assign some value to that variable exactly once. Further attempts to modify the variable will result in an error. What I am after: I want to make sure that any and all single-ton classes I define can be predictably instantiated exactly once in my program (more details at the bottom). My approach to realizing my goal is to use extern to declare a global reference to the single-ton (which I will later instantiate at a time I choose. What I have sort of looks like this, namespace Global { extern Singleton& mainInstance; // not defined yet, but it will be later! } int main() { // now that the program has started, go ahead and create the singleton object Singleton& Global::mainInstance = Singleton::GetInstance(); // invalid use of qualified name Global::mainInstance = Singleton::GetInstance(); // doesn't work either :( } class Singleton { /* Some details ommited */ public: Singleton& GetInstance() { static Singleton instance; // exists once for the whole program return instance; } } However this does not really work, and I don't know where to go from here. Some details about what I'm up against: I'm concerned about threading as I am working on code that will deal with game logic while communicating with several third-party processes and other processes I will create. Eventually I would have to implement some kind of synchronization so multiple threads could access the information in the Singleton class without worry. Because I don't know what kinds of optimizations I might like to do, or exactly what threading entails (never done a real project using it), I was thinking that being able to predictably control when Singletons were instantiated would be a Good Thing. Imagine if Process A creates Process B, where B contains several Singletons distributed against multiple files and/or libraries. It could be a real nightmare if I can not reliably ensure the order these singleton objects are instantiated (because they could depend on each other, and calling methods on a NULL object is generally a Bad Thing). If I were in C# I would just use the readonly keyword, but is there any way I can implement this (compiler supported) behavior in C++? Is this even a good idea? Thanks for any feedback.

  • Why do debug symbols so adversely affect the performance of threaded applications on Linux?

    - by fluffels
    Hi. I'm writing a ray tracer. Recently, I added threading to the program to exploit the additional cores on my i5 Quad Core. In a weird turn of events the debug version of the application is now running slower, but the optimized build is running faster than before I added threading. I'm passing the "-g -pg" flags to gcc for the debug build and the "-O3" flag for the optimized build. Host system: Ubuntu Linux 10.4 AMD64. I know that debug symbols add significant overhead to the program, but the relative performance has always been maintained. I.e. a faster algorithm will always run faster in both debug and optimization builds. Any idea why I'm seeing this behavior?

  • Browser graphics: Java Applet vs Flash vs anything else?

    - by Andrey
    Hello! We sell photoalbums which our customers create theirselves using a client album editor program (for Windows). Now we are going to develop an online program so customers could create their albums in the browser: upload photos and edit them. This is going to be a rich browser application with full graphics support. The problem is what technology to use? Our server application is build in Java and we think about Java Applets so that we could reuse some Java-code. We are also not very familiar with Flash. But some people say that Flash is preferred. Maybe there're some modern technologies now? SVG or some Google technologies (like GWT but with graphics support) or something? What do you think? Thanks in advance!

  • How to store Hierarchical K-Means tree for a large number of images, using Opencv?

    - by AquaAsh
    I am trying to make a program that will find similar images from a dataset of images. The steps are 1)extract SURF descriptors for all images 2)store the descriptors 3)Apply knn on the stored descriptors 4)Match the stored descriptors to the query image descriptor using KNN Now each images SURF descriptor will be stored as Hierarchical k means tree, now do I store each tree as a separate file or is it possible to build some sort of single tree with all the images descriptors and updated as images are added to dataset. This is the paper I am basing the program on www.ijest.info/docs/IJEST10-02-03-13.pdf.

  • How to indicate to user that a command affects a subset of a multiple selection?

    - by Zamboni
    Here is an example that illustrates my question. I have a program that lists 1000 items. I select 10 of 1000 items. The program enables a button indicating that a command is available for my selection. I click the button, and a window appears. I make some change in the window and click OK. The command changes 5 of the 10 items in my multiple selection, and those 5 changed items now reflect a modified state in my list. My question is: How do I indicate to user that the command affects a subset of a multiple selection before clicking OK? Can anyone cite examples of existing products that handle this scenario well?

  • JSP cant find bean Class using "" modifiers

    - by Ravana
    Hey I'm using Netbeans for my IDE and I'm getting an error when I try to run my EJB program. I get an error when I declare and give the path of the class in my JSP to a bean. <jsp:useBean id="book" class="BookBean.Book" scope="application" /> <jsp:setProperty name="book" property="*" /> When I run the program I get this error javax.servlet.ServletException: java.lang.InstantiationException: class BookBean.Book : java.lang.IllegalAccessException: Class java.beans.Beans can not access a member of class BookBean.Book with modifiers "" and java.lang.InstantiationException: class BookBean.Book : java.lang.IllegalAccessException: Class java.beans.Beans can not access a member of class BookBean.Book with modifiers "" I removed the "" and put in '' to see if that works, but it doesn't. Any idea? I also put a breakpoint there and it def. is the root of the problem. Thanks.

  • How to run xunit in Visual Studio 2012?

    - by user1978421
    I am very new to unit testing. I have been following the procedures for creating a unit test in visual studio 2012 on http://channel9.msdn.com/Events/TechEd/Europe/2012/DEV214. The test just won't start. And it will prompt me "A project with an Output Type of Class Library cannot be started directly. In order to debug this project, add an executable project to this solution which references the library project. Set an executable project as the startup project. Even though I attached the unit test class code to a console program, the test does not start and the test explorer is empty. In the video, it doesn't need to have any running program. The lady only created a class library, and the test will run. what should I do? Note. there is no "create unit test" on the mouse right click menu

  • Make DLL dependent to other DLLs (Visual Studio IDE)

    - by Artefacto
    I'm having an inconsistency when compiling a DLL (let's call it x.dll) by calling cl.exe obj1.obj obj2.obj ... lib1.lib lib2.lib ... /link /out:x.dll /dll /debug and When using the IDE (which calls link directly, I believe). Let's say lib1.lib is an import library for lib1.dll. Opening the DLL generated by calling cl.exe in the depency walker shows it depends on lib1.dll. However, when using the IDE, the generated program is smaller and does not depend on lib1.dll. This IDE-generated image makes the program that uses x.dll crash sometimes. The question is: how do I get the correct behaviour from the IDE?

  • infix formula in the input

    - by gcc
    input: sqrt(2 - sin(3*A/B)^2.5) + 0.5*(C*~(D) + 3.11 +B) a b /*there are values for a,b,c,d */ c d input : sqrt(2 - asin(3*A/B)^2.5) +cos(0.5*(C*~(D)) + 3.11 +B) a b /*there are values for a,b,c,d */ c d input: sqrt(2 - sin(3*A/B)^2.5)/(0.5*(C*~(D)) + sin(3.11) +ln(B)) /*max lenght of formula is 250 characters*/ a b /*there are values for a,b,c,d */ c /*each variable with set of floating numbers*/ d As you can see infix formula in the input depends on user. My program will take a formula and n-tuples value. Then it calculate the results for each value of a,b,c and d. If you wonder I am saying ;outcome of program is graph. I dont know way how to store the formula so that I can do my job with easy. can you show me? a,b,c,d is letters cos,sin,sqrt,ln is function

  • [C#] Running elevated applications on user login with UAC?

    - by Alex
    I need to start a program every time the user logs in, but I cannot do this without being met by a UAC dialog asking for permissions for that application. Is there any way to have an application start up on user login without the user having to answer the UAC prompt? I was thinking about running a service, but this would be a last resort. I saw something about an Application Compatibility Toolkit to disable UAC for certain applications, but I feel this is too big of a hassle - even services would be easier to program. I was just wondering if there is an even easier solution I am missing. Thanks in advance.

  • Samsung UMPC, Built in Camera doesn't support DirectX how can I use it?

    - by Markive
    The Samsung Q1 Ultra, is the perfect device for my software except that the built in camera seems to be incompatible with standard DirectX drivers, so my .Net camera implementation can't use the device. I have limited experience in this area.. Even Skype can't access this camera, but a little program from Samsung can.. I've looked at the program's assemblies and it's too obfuscated to see inside so I can't see anyway to use them.. What sort of camera could this be? Are there any .Net classes / implementations I can use to access this camera?

  • How much memory is reserved when i declare a string?

    - by Bhagya
    What exactly happens, in terms of memory, when i declare something like: char arr[4]; How many bytes are reserved for arr? How is null string accommodated when I 'strcpy' a string of length 4 in arr? I was writing a socket program, and when I tried to suffix NULL at arr[4] (i.e. the 5th memory location), I ended up replacing the values of some other variables of the program (overflow) and got into a big time mess. Any descriptions of how compilers (gcc is what I used) manage memory?

  • Screen Resolution Question VS2008 - C++ CLI

    - by MrMcC
    Hi, I have a program that has a SIZE of 800x600. I want to make this program expand if it is maximized, so that all the elements(buttons, picturebox's) change size to fit the new ratio depending on the users windows screen resolution. The way I am thinking to approach this is to take the users screen resolution and manual change the size of everything, and do this for all common resolutions, if a user has some rare resolution, ill just make it so the maximize/minimize buttons are disabled. But this will be very very time consuming as there are lots of elements in the forms, and their are multiple forms..... Basically, is there a shortcut? Perhaps a built in feature or some kind of add in for VS2008. What are some methods to tackle this issue?

  • Redirect window of command line tool to your app (Windows)

    - by dribler
    Hello, is there a way (on Windows XP+) to redirect the output of a window created by a process created with e.g. CreateProcess to a window of your own program? I'd like to make a nicer GUI for ffplay.exe which is an open source video player. It is a command line tool, which opens a simple window in which it plays back the video. Can I "capture" this window and display the output in my own program somehow? Thanks for any hints you can provide.

  • Reordering Lists like playlists in the media player

    - by CrazyBS
    Hi, I have a list of items that are displayed using a ListView from a SQLCursor. The SQL table includes(as well as other things) a _id field and an order field. I use the order field to sort the list before it gets to the ListView. What I need is a widget like the MediaPlayer has in its playlist view. It allows you to click the icon and drag the item in the playlist around and put it into a new order. With that ability I can then retrieve the new order and update the SQL table with the new order. However, I am not having any luck finding any clues to help me add that functionality into my program. The question is whether I can use existing functions to help me, or do I need to manually program motion events and such until I get nearly the same functionality.

  • Compiling C Source with Makefile in Windows

    - by humoeba
    I'm trying to compile a downloaded program in Windows. The program is usually run in Linux, but is programmed to also run in Windows (the code has #if defined(_WIN32)'s in it, and claims to work with borland free tools). When I try to use make from the command line, it tells me "Incorrect command line argument: -C". In the makefile, there are many lines that say "make -C" followed by a directory name. Does this syntax not work in Windows? What is a correct way to do this? Is there any way to compile this for native use in Windows with this makefile?
