  • C++ AMP, for loops to parallel_for_each loop

    - by user1430335
    I'm converting an algorithm to make use of the massive acceleration that C++ AMP provides. The stage I'm at is putting the for loops into the known parallel_for_each loop. Normally this should be a straightforward task to do but it appears more complex then I first thought. It's a nested loop which I increment using steps of 4 per iterations: for(int j = 0; j < height; j += 4, data += width * 4 * 4) { for(int i = 0; i < width; i += 4) { The trouble I'm having is the use of the index. I can't seem to find a way to properly fit this into the parallel_for_each loop. Using an index of rank 2 is the way to go but manipulating it via branching will do harm to the performance gain. I found a similar post: Controlling the index variables in C++ AMP. It also deals about index manipulation but the increment aspect doesn't cover my issue. With kind regards, Forcecast

  • Save a tab in a jQuery Modal Window for future Display

    - by Shauni
    Hello, long time reader, first time poster. I’m coming with an issue that many of you will find trivial but I’m bashing my head against it for too long time and I can’t seems to find any clue on the internet. As a total scrubs with JavaScript, I’m trying to use JQuery.ui smartmodal windows (v 1.8.rc1) for displaying two football teams in two separate tabs. Like France in Tab(0) and England in Tab(1). When I open this modal window, the first tab (France) is always opened by default. Everything’s fine until here : I’m trying to improve this modal window by remembering what was the last Tab the user was looking when he closed the modal, for reopening it (in spite of the first tab, by default) when the user will reopen this modal latter on. I’ve already tried to use the “selecting & loading a jquery tab programatically » method but without any kind of success, and I’m slowly running out of options (and time). Thanks for reading me, if you have any idea on how can I use a parameter in the smartmodal call, that would greatly help me.

  • Hiding Url for asp.net page

    - by user204588
    Hello, I'm creating an html page that is posted to another page for processing. I don't want users to see the weird URL they are redirected to and I was using FRAMES but I can't figure out how to add my HTML page dynamically because I need the variables and either add frames or try another way to accomplish this. So, based on how I'm creating the page below, how can I hide the URL and add something that I want. Here is how I'm creating the page. StringBuilder sb = new StringBuilder(); sb.Append("<html><head></head>"); sb.Append("<body onload=\"document.frmLaunch.submit();\">"); sb.Append("<form name=\"frmLaunch\" action=\"" + variableTargetURL + "\" method=\"post\">"); sb.Append("<input type=hidden name=\"testVariable\" value=\"" + variableTest + "\">"); sb.Append("</form>"); sb.Append("</body></html>"); HttpResponse response = HttpContext.Current.Response; response.Clear(); response.Write(sb.ToString()); response.End();

  • Installing Image_Graph and using with BASE

    - by PPowerHouseK
    Hello all, I have Windows 7 with the latest XAMPP installation. I configured BASE to work, for the most part. My problem is that in BASE, when I click on the graph alerts button, I get this error: Error loading the Graphing library: Check your Pear::Image_Graph installation! * Image_Graph can be found here:at http://pear.veggerby.dk/. Without this library no graphing operations can be performed. * Make sure PEAR libraries can be found by php at all: pear config-show | grep "PEAR directory" PEAR directory php_dir /usr/share/pear This path must be part of the include path of php (cf. /etc/php.ini): php -i | grep "include_path" include_path => .:/usr/share/pear:/usr/share/php => .:/usr/share/pear:/usr/share/php</code> I think it may have to do with the include path of the php.ini so here is what it currently says: ;;;;;;;;;;;;;;;;;;;;;;;;; ; Paths and Directories ; ;;;;;;;;;;;;;;;;;;;;;;;;; ; UNIX: "/path1:/path2" ;include_path = ".:/php/includes" ; ; Windows: "\path1;\path2" ;include_path = ".;c:\php\includes" ; ; PHP's default setting for include_path is ".;/path/to/php/pear" ; http://php.net/include-path include_path = ".;C:\xampp\php\PEAR" I am really at a loss as to how to resolve this. I searched for a while for some documentation but most referred to installing on ubuntu. I don't know any pear or php, so if you know how to fix this please explain thoroughly. I am willing to supply as much information as needed.

  • Persisting object changes from child form to parent form based on button press.

    - by Shyran
    I have created a form that is used for both adding and editing a custom object. Which mode the form takes is provided by an enum value passed from the calling code. I also pass in an object of the custom type. All of my controls at data bound to the specific properties of the custom object. When the form is in Add mode, this works great as when the controls are updated with data, the underlying object is as well. However, in Edit mode, I keep two variables of the custom object supplied by the calling code, the original, and a temporary one made through deep copying. The controls are then bound to the temporary copy, this makes it easy to discard the changes if the user clicks the Cancel button. What I want to know is how to persist those changes back to the original object if the user clicks the OK button, since there is now a disconnect because of the deep copying. I am trying to avoid implementing a internal property on the Add/Edit form if I can. Below is an example of my code: public AddEditCustomerDialog(Customer customer, DialogMode mode) { InitializeComponent(); InitializeCustomer(customer, mode); } private void InitializeCustomer(Customer customer, DialogMode mode) { this.customer = customer; if (mode == DialogMode.Edit) { this.Text = "Edit Customer"; this.tempCustomer = ObjectCopyHelper.DeepCopy(this.customer); this.customerListBindingSource.DataSource = this.tempCustomer; this.phoneListBindingSource.DataSource = this.tempCustomer.PhoneList; } else { this.customerListBindingSource.DataSource = this.customer; this.phoneListBindingSource.DataSource = this.customer.PhoneList; } }

  • long startup time...Need help

    - by Jeff
    My app is all done and working great. So now I ran it on a old iPhone and the app takes 17.3 seconds to start!?!? i spent a lot of time looking into it and i found that the reason it is taking so long to load is i have a lot of views and each view has a png background image. All my views and made in IB and in my code: #import "MyTestAppDelegate.h" #import "MyTestViewController.h" @implementation MyTestAppDelegate @synthesize window; @synthesize viewController; - (void)applicationDidFinishLaunching:(UIApplication *)application { // Override point for customization after app launch [window addSubview:viewController.view]; [window makeKeyAndVisible]; } - (void)dealloc { [viewController release]; [window release]; [super dealloc]; } @end At the end of the code where is says: [window addSubview:viewController.view]; the app seems to be loading all the views in the nib at the same time. All the png's from all the views are about 12mb. There is no need for the app to load all the views at the same time during startup. Is there a way i can only load the first "home" view at startup? (All the views are part of the same nib.)

  • NullPointerException on Activity Testint Tutorial

    - by Bendik
    Hello, I am currently trying the activity testing tutorial (Found here), and have a problem. It seems that whenever I try to call something inside the UIThread, I get a java.lang.NullPointerException. public void testSpinnerUI() { mActivity.runOnUiThread( new Runnable() { public void run() { mSpinner.requestFocus(); } }); } This gives me: Incomplete: java.lang.NullPointerException and nothing else. I have tried this on two different samples now, with the same result. I tried with a try/catch clause around the mSpinner.requestFocus() call, and it seems that mSpinner is null inside the thread. I have set it properly up with the setUp() function found in the same sample, and a quick assertNotNull( mSpinner ) shows me that mSpinner is in fact not null after the setUp() function. What can be the cause of this? EDIT; ok, some more testing has been done. It seems that the application that is being tested resets between each test. This essentially makes me have to reinstantiate all variables between each test. Is this normal?

  • Help regarding multi-threading in MFC,please help me firends!

    - by kiddo
    Hello all,in my application there is a small part of function,in which it will read files to get some information,the number of filecount would be utleast 50,So I thought of implementing threading.Say if the user is giving 50 files,I wanted to separate it as 5 *10, 5 thread should be created,so that each thread can handle 10 files which can speed up the process.And also from the below code you can see that some variables are common.I read some articles about threading and I am aware that only one thread should access a variable/contorl at a me(CCriticalStiuation can be used for that).For me as a beginner,I am finding hard to imlplement what I have learned about threading.Somebody please give me some idea with code shown below..thanks in advance file read function:// void CMyClass::GetWorkFilesInfo(CStringArray& dataFilesArray,CString* dataFilesB, int* check,DWORD noOfFiles,LPWSTR path) { CString cFilePath; int cIndex =0; int exceptionInd = 0; wchar_t** filesForWork = new wchar_t*[noOfFiles]; int tempCheck; int localIndex =0; for(int index = 0;index < noOfFiles; index++) { tempCheck = *(check + index); if(tempCheck == NOCHECKBOX) { *(filesForWork+cIndex) = new TCHAR[MAX_PATH]; wcscpy(*(filesForWork+cIndex),*(dataFilesB +index)); cIndex++; } else//CHECKED or UNCHECKED { dataFilesArray.Add(*(dataFilesB+index)); *(check + localIndex) = *(check + index); localIndex++; } } WorkFiles(&cFilePath,dataFilesArray,filesForWork, path, cIndex); dataFilesArray.Add(cFilePath); *(check + localIndex) = CHECKED; }

  • Could someone help me debug my app (not very big)?

    - by Alex
    Not sure if this kind of help is accepted to ask for here, tell me if it isn't. It has to get done before tomorrow, it's not entirerly finished but it should work somewhat ok by now. I'm trying to use the Eclipse debugger (not very used to it). I have my top-level or main class, which is Game, in which I have a constructor and a main method. In the main method I create a new "Game", initiating the constructor. public static void main(String[] args){ Game chess = new Game(); } public Game(){ Board board = new Board(); That's the first thing the debugger reacts to: Thread [main] (Suspended) ClassNotFoundException(Object).<init>() line: 20 [local variables unavailable] ClassNotFoundException(Throwable).<init>(String, Throwable) line: 217 ClassNotFoundException(Exception).<init>(String, Throwable) line: not available ClassNotFoundException.<init>(String) line: not available URLClassLoader$1.run() line: not available AccessController.doPrivileged(PrivilegedExceptionAction<T>, AccessControlContext) line: not available [native method] Launcher$ExtClassLoader(URLClassLoader).findClass(String) line: not available Launcher$ExtClassLoader.findClass(String) line: not available Launcher$ExtClassLoader(ClassLoader).loadClass(String, boolean) line: not available Launcher$AppClassLoader(ClassLoader).loadClass(String, boolean) line: not available Launcher$AppClassLoader.loadClass(String, boolean) line: not available Launcher$AppClassLoader(ClassLoader).loadClass(String) line: not available Game.<init>() line: 15 Game.main(String[]) line: 11 Line 11 is the one line in my main method, line 15 is the instantiation of "board".

  • Where to start to create an HTML website with 2 tables read from csv files using anything but php

    - by CodingIsAwesome
    I want to design a website which displays on loading two tables each with it's respective data from a csv file. Then every minute the website automatically refreshes. This problem seems so simple! But yet the solution eludes me. All of the files will be contained in 1 directory, not on a server but on a local machine. Such as sitting on the desktop. I understand if I use javascript I have to use ADO, and I'm still trying to work out how to use ASP. I am new with both languages. So far the only restriction is that I can't use PHP. So the jist so far as I can think right now is: 1. read the file 2. place the file into an array by splitting at the commas 3. write the array into td's ????? 4. then print all this out into a div ???? I have googled my heart out and can't seem to find what I'm looking for. or even piece together what I'm looking for. Everything with javascript and ADO's leads me to dead ends, I can't find anything on ASP that is helpful. Could someone please write up some sample code for a resource? Or have a better solution?

  • ASP.NET UserControl Caching

    - by Adam
    Hi, This thing is driving me nuts. I have a UserControl that is called WebUserControl. I need to cache this control, so I put the following in the WebUserControl.ascx: <%@ OutputCache Duration="240" VaryByParam="FeedName" %> Then I have the Default.aspx file in which I have: <div class="divInnerLeft" id="L1" runat="server"> <uc1:WebUserControl FeedId="a1" ID="a1" runat="server" FeedName=""/> </div> <div class="divInnerMiddle" id="M1" runat="server"> <uc1:WebUserControl FeedId="a3" ID="a3" runat="server" FeedName=""/> </div> In the Page_Load event I set the FeedName property - according to the user preferences. The problem is that after initially loading the page, the controls are generated OK. But then, in the Page_Load event they are not available again. So the a1 and a3 are null and I cannot set the FeedName for different user. How to solve this? Thanks!

  • C++ privately contructed class

    - by Nona Urbiz
    How can I call a function and keep my constructor private? If I make the class static, I need to declare an object name which the compiler uses to call the constructor, which it cannot if the constructor is private (also the object would be extraneous). Here is the code I am attempting to use (it is not compilable): I want to keep the constructor private because I will later be doing a lot of checks before adding an object, modifying previous objects when all submitted variables are not unique rather than creating new objects. #include <iostream> #include <fstream> #include <regex> #include <string> #include <list> #include <map> using namespace std; using namespace tr1; class Referral { public: string url; map<string, int> keywords; static bool submit(string url, string keyword, int occurrences) { //if(Referrals.all.size == 0){ // Referral(url, keyword, occurrences); //} } private: list<string> urls; Referral(string url, string keyword, int occurrences) { url = url; keywords[keyword] = occurrences; Referrals.all.push_back(this); } }; struct All { list<Referral> all; }Referrals; int main() { Referral.submit("url", "keyword", 1); }

  • c++ code cons/pros

    - by VirusEcks
    below i have a code that runs in most of my simple programs .. . i want to know if it's good/bad ... and cons/pros . . win32 header file: win32.h #include <windows.h> #include <process.h> #include <stdarg.h> main header file: inc.h #include "win32.h" #ifndef INCS #define INCS #define DD #else #define DD extern #endif #ifndef VARS #define titlen L"my program" #endif DD wchar_t gtitle[512]; DD wchar_t gclass[512]; DD wchar_t gdir[32767]; #include "resources.h" #include "commonfunctions.h" then all files have something like this commonfunctions.h DD inline bool icmp( const char *String1, const char *String2 ) { if ( _stricmp( String1, String2 ) == 0 ) { return true; } return false; } DD inline bool scmp( const char *String1, const char *String2 ) { if ( strcmp( String1, String2 ) == 0 ) { return true; } return false; } all global variables have DD infront of them and all functions have DD too . is there a bad side of this ? . i came up with this idea and it wasn't problematic at all in small programs . but before i apply it in a large project will it be problematic ?. thanks in advance.

  • Unsure how to come up with a good design

    - by Mewzer
    Hello there, I am having trouble coming up with a good design for a group of classes and was hoping that someone could give me some guidance on best practices. I have kept the classes and member functions generic to make the problem simpler. Essentially, I have three classes (lets call them A, B, and C) as follows: class A { ... int GetX( void ) const { return x; }; int GetY( void ) const { return y; }; private: B b; // NOTE: A "has-a" B int x; int y; }; class B { ... void SetZ( int value ) { z = value }; private: int z; C c; // NOTE: B "has-a" C }; class C { private: ... void DoSomething(int x, int y){ ... }; void DoSomethingElse( int z ){ ... }; }; My problem is as follows: Class A uses its member variables "x" and "y" a lot internally. Class B uses its member variable "z" a lot internally. Class B needs to call C::DoSomething(), but C::DoSomething() needs the values of X and Y in class A passed in as arguments. C::DoSomethingElse() is called from say another class (e.g. D), but it needs to invoke SetZ() in class B!. As you can see, it is a bit of a mess as all the classes need information from one another!. Are there any design patterns I can use?. Any ideas would be much appreciated ....

  • Read large amount of data from file in Java

    - by Crozin
    Hello I've got text file that contains 1 000 002 numbers in following formation: 123 456 1 2 3 4 5 6 .... 999999 100000 Now I need to read that data and allocate it to int variables (the very first two numbers) and all the rest (1 000 000 numbers) to an array int[]. It's not a hard task, but - it's horrible slow. My first attempt was java.util.Scanner: Scanner stdin = new Scanner(new File("./path")); int n = stdin.nextInt(); int t = stdin.nextInt(); int array[] = new array[n]; for (int i = 0; i < n; i++) { array[i] = stdin.nextInt(); } It works as excepted but it takes about 7500 ms to execute. I need to fetch that data in up to several hundred of milliseconds. Then I tried java.io.BufferedReader: Using BufferedReader.readLine() and String.split() I got the same results in about 1700 ms, but it's still too many. How can I read that amount of data in less that 1 second? The final result should be equal to: int n = 123; int t = 456; int array[] = { 1, 2, 3, 4, ..., 999999, 100000 };

  • Why does applying this gradient style break my silverlight app ?

    - by Robotsushi
    I am having some issues with applying a gradient to a RadButton. I have a gradient definition in my styles resource dictionairy like so : <LinearGradientBrush x:Key="GridView_HeaderBackground" EndPoint="0.5,1" StartPoint="0.5,0"> <GradientStop Color="#FF5B5B5B" Offset="1"/> <GradientStop Color="#FF868686"/> <GradientStop Color="#FF4F4F4F" Offset="0.42"/> <GradientStop Color="#FF0E0E0E" Offset="0.43"/> </LinearGradientBrush> When i apply this gradient directly to the background of a RadButton everything works. Here is the button and the template definition: Button <telerik:RadButton Margin="5,10,5,0" Click="RadButton_Click" Tag="30" Content="30 Days" Style="{StaticResource SliderButton}" Background="{StaticResource GridView_HeaderBackground}" /> Template: <!-- Style Template for Slider RadButton --> <Style x:Key="SliderButton" TargetType="telerik:RadButton"> <Setter Property="Height" Value="30" /> <Setter Property="Foreground" Value="#FFFFFF" /> <Setter Property="BorderThickness" Value="0" /> <Setter Property="Margin" Value="5,2" /> </Style> However when applying this gradient in the resource dictionary, my application will not load it simply gets to the silverlight loading screen and then never proceeds Here is the button and template which breaks my app. Button: <telerik:RadButton Margin="5,10,5,0" Click="RadButton_Click" Tag="30" Content="30 Days" Style="{StaticResource SliderButton}" /> Template: <!-- Style Template for Slider RadButton --> <Style x:Key="SliderButton" TargetType="telerik:RadButton"> <Setter Property="Background" Value="{StaticResource GridView_HeaderBackground}" /> <Setter Property="Height" Value="30" /> <Setter Property="Foreground" Value="#FFFFFF" /> <Setter Property="BorderThickness" Value="0" /> <Setter Property="Margin" Value="5,2" /> </Style> When i observe the js error console in google chrome i notice the following error is produced: "Cannot find a resource with the name/key ResourceWrapper"

  • Safe json parsing with jquery?

    - by user246114
    Hi, I am using jquery with json. My client pages generate json, which I store on my server. The clients can then fetch the json back out later, parse, and show it. Since my clients are generating the json, it may not be safe. I think jquery uses eval() internally. Is that true? Is there a way to use the native json parsers from the browsers where available, otherwise fall back to manual parsing if not? I'm new to jquery so I don't know where I'd insert my own parsing code. I'm doing something like: $.ajax({ url: 'myservlet', type: 'GET', dataType: 'json', timeout: 1000, error: function(){ alert('Error loading JSON'); }, success: function(json){ alert("It worked!: " + json.name + ", " + json.grade); } }); so in the success() method, the json object is already parsed for me. Is there a way to catch it as a raw string first? Then I can decide whether to use the native parsers or manual parsing (hoping there's a jquery plugin for that..). The articles I'm reading are all from different years, so I don't know if jquery has already abandoned eval() already for json, Thank you

  • Image does not update when file name remains the same in XCode 3.1.2

    - by vman049
    Hi Everyone, I'm using XCode version 3.1.2 and am developing for iPhone using the Simulator with iOS 2.2.1 on Leopard. I had an image file named "img.jpg" in my project which I decided to switch for a different file. After adding the new file into the XCode Resources folder, I removed the first file and renamed the new file to the same name as the previous one, "img.jpg." When I run my program, however, the Simulator loads the old image instead of the new one, even though the old one has been deleted from disk (not just the reference). I tried changing the name of the file to "img2.jpg," and it worked like it should - loading the new image, but I want to keep the name "img.jpg." I ran a search with Spotlight for "img.jpg" to see if there was another copy stored somewhere that XCode was using, but it only returned my new image file. I have tried uninstalling the app from the Simulator and running the application again, but that also does not fix the problem. What must I do for XCode to recognize that I want to use the new image file and not the old one? Thanks for your help!!

  • Overhead of calling tiny functions from a tight inner loop? [C++]

    - by John
    Say you see a loop like this one: for(int i=0; i<thing.getParent().getObjectModel().getElements(SOME_TYPE).count(); ++i) { thing.getData().insert( thing.GetData().Count(), thing.getParent().getObjectModel().getElements(SOME_TYPE)[i].getName() ); } if this was Java I'd probably not think twice. But in performance-critical sections of C++, it makes me want to tinker with it... however I don't know if the compiler is smart enough to make it futile. This is a made up example but all it's doing is inserting strings into a container. Please don't assume any of these are STL types, think in general terms about the following: Is having a messy condition in the for loop going to get evaluated each time, or only once? If those get methods are simply returning references to member variables on the objects, will they be inlined away? Would you expect custom [] operators to get optimized at all? In other words is it worth the time (in performance only, not readability) to convert it to something like: ElementContainer &source = thing.getParent().getObjectModel().getElements(SOME_TYPE); int num = source.count(); Store &destination = thing.getData(); for(int i=0;i<num;++i) { destination.insert(thing.GetData().Count(), source[i].getName(); } Remember, this is a tight loop, called millions of times a second. What I wonder is if all this will shave a couple of cycles per loop or something more substantial? Yes I know the quote about "premature optimisation". And I know that profiling is important. But this is a more general question about modern compilers, Visual Studio in particular.

  • Can a member struct be zero-init from the constructor initializer list without calling memset?

    - by selbie
    Let's say I have the following structure declaration (simple struct with no constructor). struct Foo { int x; int y; int z; char szData[DATA_SIZE]; }; Now let's say this struct is a member of a C++ class as follows: class CFoobar { Foo _foo; public: CFoobar(); }; If I declare CFoobar's constructor as follows: CFoobar::CFoobar() { printf("_foo = {%d, %d, %d}\n", _foo.x, _foo.y,_foo.z); for (int x = 0; x < 100; x++) printf("%d\n", _foo.szData[x]); } As you would expect, when CFoobar's constructor runs, garbage data gets printed out Obviously, the easy fix is to memset or ZeroMemory &_foo. It's what I've always done... However, I did notice that if add _foo to the constructor's initialization list with no parameters as follows: CFoobar::CFoobar() : _foo() { That this appears to zero-out the member variables of _foo. At least that was the case with g++ on linux. Now here's my question: Is this standard C++, or is this compiler specific behavior? If it's standard behavior, can someone quote me a reference from an official source? Any "gotchas" in regards to implicit zero-init behavior with more complicated structs and classes?

I am able to access servlet variables from the new servlet but I am not aware of how to access the value of the html generated code. thanks, Here is the servlet that gets the text input public class ServletB extends HttpServlet { public void doGet(HttpServletRequest request, HttpServletResponse response) throws IOException, ServletException { response.setContentType("text/html"); String value = System.getProperty("card"); PrintWriter out = response.getWriter(); out.println("<center><h1>Your preffered method of payment is "+value+"</h1><br />"); out.println("Please Enter Card Number<input type =\"text\" name = \"number\"/><form action=\"http://codd.cs.gsu.edu:9999/cpereyra183/servlet/ServletC\"><input type =\"submit\" value=\"Continue\" /><input type=\"button\" value=\"Cancel\" /></center>"); } }} This is the servlet the first servlet redirects to all I do is try to do is output the text input public class ServletC extends HttpServlet { public void doGet(HttpServletRequest request, HttpServletResponse response) throws IOException, ServletException { response.setContentType("text/html"); String value = System.getProperty("card"); PrintWriter out = response.getWriter(); out.println(request.getParameter("number")); } }

  • How to add an object to a html string?

    - by Philippe Maes
    I'm trying to load several images by a drop action and than resizing them and adding them as a thumbnail. The resize part is very important because the images can be very large and I want to make the thumbnails small of size. Here is my code: loadingGif(drop); for (var i=0;i<files.length;i++) { var file = files[i]; var reader = new FileReader(); reader.onload = function(e) { var src = e.target.result; var img = document.createElement('img'); img.src = src; var scale = 100/img.height; img.height = 100; img.width = scale*img.width; output.push('<div id="imagecontainer"><div id="image">'+img+'</div><div id="delimage"><img src="img/del.jpg"" /></div></div>'); if(output.length == files.length) { drop.removeChild(drop.lastChild); drop.innerHTML += output.join(''); output.length = 0; } } reader.readAsDataURL(file); } As you can probably tell I insert a loading gif image in my dropzone until all files are loaded (output.length == files.length). When a file is loaded I add html to an array which I will print if the load is complete. The problem is I can't seem to add the img object (I need this object to resize the image) to the html string, which seems obvious as the img is an object... So my question to you guys is: how do I do this? :)
