  • Spring 3 Annotations

    - by jboyd
    I can't get spring annotations to work at all, I'm just trying to get the simplest thing to work... .../mycontext/something - invokes method: @RequestMapping(value = "/something") @ResponseBody public String helloWorld() { System.out.println("hello world"); return "Hello World"; } My main problem is no matter how hard I try, I can't find a complete SIMPLE example of the configuration files needed, every spring tutorial is filled with junk, I just one one controller to handle a request with a mapping and can't get it to work does anyone know of a simple and complete spring example. pet-clinic is no good, it's way too complicated, I have a tiny basic use case and it's proving to be a real pain to get working (this always happens with Spring)

  • C++11 VS 2012 functor seems to choke when I have more than 5 parameters

    - by bobobobo
    function <void ( int a, int b, int ia, int ib, bool rev, const Vector4f& color )> benchTris = [&pts]( int a, int b, int ia, int ib, bool rev, const Vector4f& color ) { } The error is: error C2027: use of undefined type 'std::_Get_function_impl<_Tx>' with [ _Tx=void (int,int,int,int,bool,const Vector4f &) ] main.cpp(374) : see reference to class template instantiation 'std::function<_Fty>' being compiled with [ _Fty=void (int,int,int,int,bool,const Vector4f &) ] Works ok if I remove ONE parameter, for example a from the front: function <void ( int b, int ia, int ib, bool rev, const Vector4f& color )> benchTris = [&pts]( int b, int ia, int ib, bool rev, const Vector4f& color ) { // ok } Is there some parameter limit I don't know about?

  • How to save big "database-like" class in python

    - by Rafal
    Hi there, I'm doing a project with reasonalby big DataBase. It's not a probper DB file, but a class with format as follows: DataBase.Nodes.Data=[[] for i in range(1,1000)] f.e. this DataBase is all together something like few thousands rows. Fisrt question - is the way I'm doing efficient, or is it better to use SQL, or any other "proper" DB, which I've never used actually. And the main question - I'd like to save my DataBase class with all record, and then re-open it with Python in another session. Is that possible, what tool should I use? cPickle - it seems to be only for strings, any other? In matlab there's very useful functionality named save workspace - it saves all Your variables to a file that You can open at another session - this would be vary useful in python!

  • How to share WinForms and code between 2 projects

    - by Richard Bysouth
    Hi I have a working Windows Forms app (split into an EXE and a few DLLs). Now I've been asked to look at creating another app (MyAppLite) that has only a very small subset of the functionality. Think of it as similar to MS Word Viewer vs. MS Word. Everything that I need to build MyAppLite is contained in the main solution - essentially I need to use a couple of the WinForms and whatever bits in the DLLs they call into. What would be the best way to do this? I was thinking of creating another Project in my solution for MyAppLite, then adding the necessary source files as links (using Add Existing Item Add As Link in Solution Explorer). I definitely wouldn't want to maintain 2 copies of the source code. FYI it's a .NET 2.0 VB app, using VS2008. thanks Richard

    - by Coppermill
    I have created an Attribute, call MyAttribute, which is performing some security and for some reason the Constructor is not being fired, any reason why? public class Driver { // Entry point of the program public static void Main(string[] Args) { Console.WriteLine(SayHello1("Hello to Me 1")); Console.WriteLine(SayHello2("Hello to Me 2")); Console.ReadLine(); } [MyAttribute("hello")] public static string SayHello1(string str) { return str; } [MyAttribute("Wrong Key, should fail")] public static string SayHello2(string str) { return str; } } [AttributeUsage(AttributeTargets.Method)] public class MyAttribute : Attribute { public MyAttribute(string VRegKey) { if (VRegKey == "hello") { Console.WriteLine("Aha! You're Registered"); } else { throw new Exception("Oho! You're not Registered"); }; } }

  • REST doesn't work with Sever-Client-Client setup

    - by drozzy
    I am having a problem with my current RESTful api design. What I have is a REST api which is consumed by Django web-server, which renders the HTML templates. REST api > Django webserver > HTML The problem I am encountering is that I have to reconstruct all the URLS like mysite.com/main/cities/<id>/streets/ into equivalent rest api urls on my web-server layer: api.com/cities/<id>/streets/ Thus I have a lot of mapping back and forth, but as far as I know REST says that the client (in this case my web-server) should NOT need to know how to re-construct the urls. Can REST be used for such a setup and how? Or is it only viable for Server-Client architecture. Thanks

  • How *restrict / *__restrict__ works in C / C++?

    - by Moraru Lilian
    Here is some code I wrote: #include <iostream> using namespace std; int main(void) { int i = 7; int *__restrict__ a = &i; *a = 5; int *b = &i, *c = &i; *b = 8; *c = 9; cout << **&a << endl; //*a return 0; } From what I've read, if I do " *a = 5 ", it changes the value of the memory he, "a", is pointing to, after that the memory to which he is pointing to should not be modified by anyone else except "a", which means that these program is wrong because "b" and "c" modify it after that. Or, even if "b" modifies "i" first, after that only "a" should have access to that memory( "i" ). Am I getting it correctly?

  • Unable to catch exception from Activator.CreateInstance.

    - by Patrik Hägne
    OK, I admit it this code will just look weird to you, and that's because it is weird. This is just code to reproduce the behavior, not code I want to use. class Program { static void Main(string[] args) { try { Activator.CreateInstance(typeof(Func<int>), new object[] { new object(), IntPtr.Zero }); } catch { Console.WriteLine("This won't print!"); } Console.Write("Actually this will not print either!"); Console.ReadLine(); } } No matter what exception type I try to catch (the actual exception thrown is an ArgumentException as far as I can tell) the code inside the catch block will not execute. Actually execution will just stop at the Activator.CreateInstance-line.

  • Export contacts from ACT, Salesforce, Outlook, QuickBooks, etc.

    - by Mike Wallace
    What API's / SDK's / software tools are available to export contacts from popular CRM and accounting packages? What I'd like to do is offer an address book in my web application and have a button that says "Upload your contacts from X". The user could then click a few buttons and his contacts would be automagically uploaded from X. A company called Plaxo has a widget that does exactly what I am looking for, BUT: They only support a limited number of data sources (I am most interested in ACT, Salesforce, Outlook, and QuickBooks), and They only support e-mail addresses. I am most interested in street addresses ("123 Main St, Anywhere, CA, 90123")

  • Sencha Touch 2: List does not display in Panel

    - by jrboddie
    I am working on an MVC app in Sencha Touch 2 and am having trouble getting a list to display in a nested panel. The structure of the app has a main view which is a tab panel. One of the items in the tab panel is a defined panel, xtype: 'homepanel'. An item in this panel is the list, xtype: 'newslist' that is linked to the appropriate store and model files. The list does not display unless I change its parent 'homepanel' to a type, Ext.navigation.View. What am I missing in the definition of 'homepanel' as a Panel that prevents the display of the list? Ext.define('ACSO.view.Home', { extend: 'Ext.Panel', //<--works if Ext.navigation.View xtype: 'homepanel', requires: [ 'Ext.TitleBar', 'ACSO.view.NewsList' ], config: { title: 'Home', iconCls: 'home', cls: 'home', scrollable: true, styleHtmlContent: true, items: [ { xtype: 'newslist' } ] } });

  • How is conversion of float/double to int handled in printf?

    - by Sandip
    Consider this program int main() { float f = 11.22; double d = 44.55; int i,j; i = f; //cast float to int j = d; //cast double to int printf("i = %d, j = %d, f = %d, d = %d", i,j,f,d); //This prints the following: // i = 11, j = 44, f = -536870912, d = 1076261027 return 0; } Can someone explain why the casting from double/float to int works correctly in the first case, and does not work when done in printf? This program was compiled on gcc-4.1.2 on 32-bit linux machine.

  • Process-wide hook using SetWindowsHookEx

    - by mfya
    I need to inject a dll into one or more external processes, from which I also want to intercept keybord events. That's why using SetWindowsHookEx with WH_KEYBOARD looks like an easy way to achieve both things in a single step. Now I really don't want to install a global hook when I'm only interested in a few selected processes, but Windows hooks seem to be either global or thread-only. My question is now how I would properly go about setting up a process-wide hook. I guess one way would be to set up the hook on the target process' main thread from my application, and then doing the same from inside my dll on DLL_PROCESS_ATTACH for all other running threads (plus on DLL_THREAD_ATTACH for threads started later). But is this really a good way? And more important, aren't there any simpler ways to setup process-wide hooks? My idea looks quite cumbersome und ugly, but I wasn't able to find any information about doing this anywhere.

  • Rotate a 2d matrix to the right

    I want a 2d matrix to rotate to the right, it compiles fine but when I try to the run it freezes. For example I want {{10,20,30},{40,50,60}} to rotate into {{40,10},{50,20},{60,30}} import java.util.*; public class Rotate{ public static int[][] rotate(int[][] m) { int [][] rotateM = new int[m[0].length][m.length]; for (int i= 0; i< m.length; i= i++){ for (int j= 0; j< m[0].length; j= j++){ rotateM[i][j] = m[j][m.length-i-1]; } } return rotateM; } public static void main(String[]args){ int[][]m = {{10,20,30}, {40,50,60}}; System.out.println(Arrays.toString(rotate(m))); } }

  • How do I replace colours in a movieclip?

    - by Oli
    I am trying to take a movieclip of a character and change the colour of their clothes. The character is comprised of vectors. So far I have semi-sucessfully used this method: stop the movieclip take the bitmap data from the current frame use threshold to replace the colour store the resulting bitmap data in an array add an onenterframe function - clear the current frame and add the bitmap data from the processed data in the array So - this works pretty well. Each frame is only processed once at the beginning and then the write to the movieclip is very quick. However! As the replacement is being performed on a bitmap there is an amount of aliasing that takes place to remove jaggies/pixelation. This produces colours that are not matched using threshold. So the main colour is replaced correctly but it is surrounded by a halo of mixed colours :( I am sure there should be a better way to do this. Any ideas or answers would be greatly apreciated - Thanks.

  • SDK for writing DVD's

    - by Matt Warren
    I need to add DVD writing functionality to an application I'm working on. However it needs to be able to write out files that are being grabbed "live" from a camera, over a long period of time. I can't wait until all the files are captured before I start writing them to the DVD, I need to write them out in chunks as I go along. I've looked at IMAPI v2, but the main problems seems to be that you need to point it to all the files you plan to write out to disk before you start the burning process. I know it has to concept of "sessions", which means you can write to the DVD in several parts, before you finally "close" it. But I was wondering if there were any other DVD writing SDK's that allow you to be constantly writing files to a DVD and in particular files that are only in memory. It would be more efficient if I didn't have to write the captured images out to hard before they are burned to DVD. The solution needs to work under .NET on Windows XP and vista

  • Processing files with C# in folders whose names contain spaces

    - by Nigel Ainscoe
    There are plenty of C# samples that show how to manipulate files and directories but they inevitably use folder paths that contain no spaces. In the real world I need to be able to process files in folders with names that contain spaces. I have written the code below which shows how I have solved the problem. However it doesn't seem to be very elegant and I wonder if anyone has a better way. class Program { static void Main(string[] args) { var dirPath = @args[0] + "\\"; string[] myFiles = Directory.GetFiles(dirPath, "*txt"); foreach (var oldFile in myFiles) { string newFile = dirPath + "New " + Path.GetFileName(oldFile); File.Move(oldFile, newFile); } Console.ReadKey(); } } Regards, Nigel Ainscoe

  • how to profile multi threaded c++ app on linux?

    - by anon
    I used to do all my linux profiling with gprof. However, with my multi threaded app, it's output appears to be inconsistent. Now, I dug this up http://sam.zoy.org/writings/programming/gprof.html howver, it's from a long time ago -- and in my gprof output, it appears my gprof is listing functions used by non-main threads. So, my questions are: 1) in 2010, can I easily use gprof to profile multi threaded linux c++ apps? (ubuntu 9.10) 2) what other tools should I look into for profiling? thanks!

  • How to solve such system with given parts of it? (maple)

    - by Kabumbus
    So I had a system #for given koefs k:=3; n:=3; #let us solve system: koefSolution:= solve({ sum(a[i], i = 0 .. k) = 0, sum(a[i], i = 0 .. k)-(sum(b[i], i = 0 .. k)) = 0, sum(i^n*a[i], i = 0 .. k)-(sum(i^(n-1)*b[i], i = 0 .. k)) = 0 }); So I have a vector like koefSolution := { a[0] = 7*a[2]+26*a[3]-b[1]-4*b[2]-9*b[3], a[1] = -8*a[2]-27*a[3]+b[1]+4*b[2]+9*b[3], a[2] = a[2], a[3] = a[3], b[0] = -b[1]-b[2]-b[3], b[1] = b[1], b[2] = b[2], b[3] = b[3]} I have a[0] so I try solve({koefSolution, a[0] = 1}); why it does not solve my system for given a[0]? ( main point here is to fill koefSolution with given a[] and b[] and optimize.)

    - by kwhohasamullet
    Hi Guys, We are a web design company going down the road of setting up a revision management system and all the processes around how we are going to use it etc. We mainly develop our websites on a Joomla and what i wanted to know is how other companies manage their repositories when dealing with a CMS. We mainly deal with template building as well as occasionally customising components/plugins we installed. My main questions are: -Is the best way to store all files (including the Joomla files) in the repo or just files that you make/ change yourself? -Do you keep a copy of the Database somewhere to account for database changes Thanks in advance
