  • OpenCV - DLL missing, but it's not?

    - by charles-22
    I am trying just a basic program with OpenCV with the following code: #include "cv.h" #include "highgui.h" int main() { IplImage* newImg; newImg = cvLoadImage("~/apple.bmp", 1); cvNamedWindow("Window", 1); cvShowImage("Window", newImg); cvWaitKey(0); cvDestroyWindow("Window"); cvReleaseImage(&newImg); return 0; } When I run this, I get The program can't start because libcxcore200.dll is missing from your computer. Try reinstalling the program to fix this problem. However, I can see this DLL. It exists. I have added the following to the input dependencies for my linker C:\OpenCV2.0\lib\libcv200.dll.a C:\OpenCV2.0\lib\libcvaux200.dll.a C:\OpenCV2.0\lib\libcxcore200.dll.a C:\OpenCV2.0\lib\libhighgui200.dll.a What gives? I'm using visual studio 2008.

  • XML-RPC with java

    - by Mona
    hi, I'm developing a server in XML-RPC using Java , but when i compile it , i get this error ServeurSomDiff.java:33: cannot find symbol symbol : method addHandler(java.lang.String,java.lang.String) location: class org.apache.xmlrpc.webserver.WebServer server.addHandler("SOMDIFF",new ServeurSomDiff ()); here 's my server : import java.util.Hashtable; import org.apache.xmlrpc.webserver.*; public class ServeurSomDiff { public ServeurSomDiff (){ } public Hashtable sumAndDifference (int x, int y) { Hashtable result = new Hashtable(); result.put("somme", new Integer(x + y)); result.put("difference", new Integer(x - y)); return result; } public static void main (String [] args) { try { WebServer server = new WebServer(8000); server.addHandler("SOMDIFF",new ServeurSomDiff()); server.start(); System.out.println("Serveur lance sur http://localhost:8000/RPC2"); } catch (Exception exception) {System.err.println("JavaServer: " + exception.toString()); } } } any ideas on how to fix this . thanks

  • CruiseControl: How to read logs from exec task

    - by Marty
    I start an external groovy script via cruisecontrol, which basically works. My problem is that if the groovy script fails I only get the "error string found" in my cruise webapp and email; its even not in the log files. The groovy script writes it output to stdout and to a logfile. How it is possible to display the output of an external script in the cruisecontrol logs? <project name="proj"> <schedule> <exec workingdir="/myscripts/folder" command="//bin/groovy" args="build.groovy -p ${project.name}.properties" errorstr="Exception"/> </schedule> </project>

  • Popularity of Git/Mercurial/Bazaar vs. which to recommend

    - by Will Robertson
    Going by the number of questions on this site for these three distributed version control systems, it seems like Git either is more popular, or is more difficult (hence requiring more questions), or has more features (hence requiring more questions). Or most probably a combination of the three. (Let's say that popularity on this site equates to popularity at large.) Here are the numbers at time of writing: [subversion] or [svn]: 2353 [git]: 726 [mercurial] or [hg]: 169 [bazaar] or [bzr]: 50 The recent historical popularity of Subversion is clearly reflected by the number of questions, indicating at least a small tipping of the scales towards Git over the Mercurial or Bazaar. It's not entirely satisfactory having three competing yet largely equivalent open source products to choose from. Personally I use Git and I'm fine with the other two. But when it comes to recommending one system over the others, I'd like to ask: can we start recommending one safely yet?

  • Prevent Windows Explorer from interfering with Directory operations.

    - by Bruno Martinez
    Sometimes, no "foo" directory is left after running this code: string folder = Path.Combine(Path.GetTempPath(), "foo"); if (!Directory.Exists(folder)) Directory.CreateDirectory(folder); Process.Start(@"c:\windows\explorer.exe", folder); Thread.Sleep(TimeSpan.FromSeconds(5)); Directory.Delete(folder, false); Directory.CreateDirectory(folder); It seems Windows Explorer keeps a reference to the folder, so the last CreateDirectory has nothing to do, but then the original folder is deleted. How can I fix the code?

  • Is it possible to implement X-HTTP-Method-Override in ASP.NET MVC?

    - by Greg Beech
    I'm implementing a prototype of a RESTful API using ASP.NET MVC and apart from the odd bug here and there I've achieve all the requirements I set out at the start, apart from callers being able to use the X-HTTP-Method-Override custom header to override the HTTP method. What I'd like is that the following request... GET /someresource/123 HTTP/1.1 X-HTTP-Method-Override: DELETE ...would be dispatched to my controller method that implements the DELETE functionality rather than the GET functionality for that action (assuming that there are multiple methods implementing the action, and that they are marked with different [AcceptVerbs] attributes). So, given the following two methods, I would like the above request to be dispatched to the second one: [ActionName("someresource")] [AcceptVerbs(HttpVerbs.Get)] public ActionResult GetSomeResource(int id) { /* ... */ } [ActionName("someresource")] [AcceptVerbs(HttpVerbs.Delete)] public ActionResult DeleteSomeResource(int id) { /* ... */ } Does anybody know if this is possible? And how much work would it be to do so...?

  • How to use Speech 2 Text in Microsoft Surface

    - by Roflcoptr
    I'd like to use some speech 2 text in my microsoft surface application. I saw that it is possible, but I don't really know where to start. Is there any framework/library available, or a code snippet, or a tutorial?? I don't even know exactly what i should google for ;) ===EDIT=== I read that it is necessary to use a grammar to recognize words. So if I want to proceed free text, is there a predefined grammar for the english language? Or is it a better choice to don't use speech2text but just audio files instead?

  • JSF f:event preRenderView is triggered by f:ajax calls and partial renders, something else?

    - by Andrew
    So we have an f:event: <f:metadata> <f:event type="preRenderView" listener="#{dashboardBacking.loadProjectListFromDB}"/> </f:metadata> Which is triggered as desired on initial page load (render). However this preRenderView event is also triggered by an ajax partial page render, which re-renders an h:panelgroup with the id projectListing, as below. <h:commandButton action="#{mrBean.addProject}" value="Create Project" title="Start a new project"> <f:ajax render="projectListing" /> </h:commandButton> I only want the dashboardBacking.loadProjectListFromDB to be called for the initial page render, but not when there is an ajax partial render. Is there a more appropriate event or method I could be using?

  • Pulling and pushing between two google code repositories

    - by Kim L
    I'll start by quoting google's blog Project owners can now create multiple repositories for their project, and they can choose to make any of those new repositories a clone of any of the project's other repositories. These project clones share the same commit access permissions as the original project and make it easier for project members to work together on new features. A common pattern in the Mercurial world is to place each "official" branch into a separate repository with naming conventions like "project-crew", "project-stable", and so on. I've done exactly this. I have my default repository and then I've cloned that repository to a repo named "dev". I intend to use the default repository as my stable repo and then the dev repo as my primary development repo. Now I'm just wondering how on earth I should go about to pull and push between the default and the dev repositories?

  • Is it actually possible to programmatically manage the state of an FTP server in IIS7?

    - by nbolton
    I'm able to manage FTP sites via the IIS manager, however, all attempts so far to manage the state of FTP sites using other means have failed, including: Using the IIS7 API (Microsoft.Web.Administration) Using WMI (with IIS6 compatibility enabled) Using the AppCmd tool in System32\inetsrv Related questions: Why am I unable to get Site.State for an FTP site, when using Microsoft.Web.Administration? Are there any workarounds I haven't tried? My objective is to manage (start/stop/query the state of) the FTP sites with C# code (as you can see from the 3 above attempted workarounds). When querying the FTP server state using WMI, it returns code 4, which means "Stopped", even though the site is definitely shown as running in IIS manager. AppCmd is useless, as it returns "Unknown" for FTP sites: c:\Windows\System32\inetsrv>appcmd list site SITE "Default Web Site" (id:1,bindings:http/*:80:,state:Stopped) SITE "Default FTP Site" (id:2,bindings:ftp/*:21:,state:Unknown)

  • Bring to front DatePicker on an UITextField

    - by crazyfr
    Hi, When an UITextField is firstResponder, I would like to bring to front an UIDatePicker (bottom part of the screen) without the "going down keyboard" (no call to UITextField resignFirstResponder). The aim is to process like UIKeyboard of UITextField which pop-up on nearly everything when it becomeFirstResponder. modalViewController seems to be fullscreen only. - showDatePicker:(id)sender { if([taskName isFirstResponder]) [taskName resignFirstResponder]; [self.view.window addSubview: self.pickerView]; // size up the picker view and compute the start/end frame origin (...) [UIView commitAnimations]; } This example is an animation of keyboard going down, and DatePicker going up, behind and not in front. Do you know a solution ? A piece of code would be welcome. Thanks in advance.

  • PHP : How to understand bitmask value of access from ini_get_all function

    - by justjoe
    i'm start to use ini_get_all function to retrieve all configuration option on a shared host server. in the end i got this chunk of array : [allow_call_time_pass_reference] => Array ( [global_value] => 1 [local_value] => 1 [access] => 6 ) [allow_url_fopen] => Array ( [global_value] => 1 [local_value] => 1 [access] => 4 ) The PHP manual just give descripstion : It's possible for a directive to have multiple access levels, which is why access shows the appropriate bitmask values. so, can anybody explain about 'access' ? ans how to understand its bitmask values ?

  • BFS traversal of directed graph from a given node

    - by p1
    Hi, My understanding of basic BFS traversal for a graph is: BFS { Start from any node . Add it to que. Add it to visited array While(que is not empty) { remove head from queue. Print node; add all unvisited direct subchilds to que; mark them as visited } } However, if we have to traverse a DIRECTED graph from a given node and not all nodes are accessible from the given node [directly or indirectly] how do we use BFS for the same. Can you please explain in this graph as well: a= b = d = e = d a= c = d Here if the starting node is b , we never print a and c. Am I missing something in the algorithm. P.S: I used "HashMap adj = new HashMap();" to create the adjacencey list to store graph Any pointers are greatly appreciated. Thanks.

  • Replace text in folder names

    - by dannyb
    How can I replace the same text in folder names in linux? Say I have "Photos_Jun", "Photos_July", "Photos_Aug", etc. whats the simplest way I can rename them like "Photos Jun", "Photos July", etc (basically I want to replace the underscore with a space " ". I have about 200 of these folders. I was looking at solution: http://stackoverflow.com/questions/1836563/how-can-i-easily-bulk-rename-files-with-perl It looks like what im looking for however, I dont know how to make a regular expression to match folders that are alphanumeric followed by a "_". All files have non-numeric names, so I think [a-zA-Z] is the right way to start. perl -e 'foreach $f (glob("File\\ Name*")) { $nf = $f; $nf =~ s/(\d+)$/sprintf("%03d",$1)/e; print `mv \"$f\" \"$nf\"`;}' Thanks for any help!

  • What calendar appears to count days since december 28, 1800?

    - by Sander Marechal
    Hello, I have been tasked to read in some data from some weird old system. The system contains many dates but they are all oddly formatted. They are integer numbers ranging from approximately 55,000 to 80,000. I know two dates for certain: 58,112 equals February 2, 1960 61,439 equals March 16, 1969 It appears to me that those integer numbers are the number of days elapsed since December 28, 1800. But I think that's a very strange date to start a calendar on. There is probably going something on with leap years and what-not that is doing to bite me in the ass later on. Does anyone recognise this calendar? Can anyone tell me what the proper way is to convert those integers to human readable dates? Thanks in advance!

  • Array Vs. Linked List

    - by Onorio Catenacci
    I apologize--this question may be a bit open-ended but I think there are probably definite, quantifiable answers to it so I'll post it anyway. A person I know is trying to learn C++ and software development (+1 to him) and he asked me why someone would want to use a linked list in preference to an array. Coding a linked list is, no doubt, a bit more work than using an array and he wondered what would justify the additional effort. I gave him the answer I know: insertion of new elements is trivial in linked list but it's a major chore in an array. But then I got to thinking about it a bit more. Besides the ease of insertion of a new element into a linked list are there other advantages to using a linked list to store a set of data vs. storing it in an array? As I said, I'm not meaning to start a long and drawn-out discussion. I'm just looking for other reasons that a developer might prefer a linked list to an array.

  • Zend_Soap_Client - Ignore HTTPS verification

    - by Vincent
    All, I want to use Zend_Soap_Client class to load WSDL from an HTTPS url. Currently, if I call like this, it gives me an error even if the WSDL is perfectly valid: $wsdlUrl = "https://abc.xyz.com/webservices/WeatherService.php?wsdl"; $soapClient = new Zend_Soap_Client($wsdlUrl); The error I receive is: SOAP-ERROR: Parsing WSDL: Couldn't load from 'https://abc.xyz.com/webservices /WeatherService.php?wsdl' : Start tag expected, '<' not found If I browse to the WSDL url in the browser, it loads up the WSDL just fine. I think Zend_Soap_Client is trying to validate the certificate and failing. Is there a way to set the SOAP option to ignore the HTTPS verification and just load the WSDL? Thanks

  • Lock-free multi-threading is for real threading experts...

    - by vdhant
    I was reading through an answer that Jon Skeet gave to a question and in it he mentioned this: As far as I'm concerned, lock-free multi-threading is for real threading experts, of which I'm not one. Its not the first time that I have heard this, but I find very few people talking about how you actually do it if you are interested in learning how to write lock-free multi-threading code. So my question is besides learning all you can about threading, etc where do you start trying to learn to specifically write lock-free multi-threading code and what are some good resources. Cheers

  • WPF: Aligning the base line of a Label and its TextBox

    - by Heinzi
    Let's say I have a simple TextBox next to a Label: <StackPanel> <StackPanel Orientation="Horizontal"> <Label Margin="3">MyLabel</Label> <TextBox Margin="3" Width="100">MyText</TextBox> </StackPanel> ... </StackPanel> This yields the following result: As you can see, the base lines of MyLabel and MyText are not aligned, which looks ugly. Of course, I could start playing around with the margins until they match up, but since this is such a common requirement I'm sure that WPF provides a much easier and more elegant solution, which I just haven't found yet...

  • How can a Delphi TForm / TPersistent object calculate its own construction and deserialization time?

    - by mjustin
    For performance tests I need a way to measure the time needed for a form to load its definition from the DFM. All existing forms inherit a custom form class. To capture the current time, this base class needs overriden methods as "extension points": start of the deserialization process after the deserialization (can be implemented by overriding the Loaded procedure) the moment just before the execution of the OnFormCreate event So the log for TMyForm.Create(nil) could look like: - 00.000 instance created - 00.010 before deserialization - 01.823 after deserialization - 02.340 before OnFormCreate Which TObject (or TComponent) methods are best suited? Maybe there are other extension points in the form creation process, please feel free to make suggestions. Background: for some of our app forms which have a very basic structure (with some PageControls and QuantumGrids) I realized that it is not database access and other stuff in OnFormShow but the construction which took most of the time (around 2 seconds) which makes me wonder where this time is spent. As a reference object I will also build a mock form which has a similar structure but no code or datamodule connections and measure its creation time.

  • Getting IIS Worker Process Crash dumps

    - by CVertex
    I'm doing something bad in my ASP.NET app. It could be the any number of CTP libraries I'm using or I'm just not disposing something properly. But when I redeploy my ASP.NET to my Vista IIS7 install or my server's IIS6 install I crash an IIS worker process. I've narrowed the problem down to my HTTP crawler, which is a multithreaded beast that crawls sites for useful information when asked to. After I start a crawler and redeploy the app over the top, rather than gracefully unloading the appDomain and reloading, an IIS worker process will crash (popping up a crash message) and continue reloading the app domain. When this crash happens, where can I find the crash dump for analysis?
