  • When are reference files(dlls) loaded?

    - by Daniel
    I wrote a program that makes a reference to Microsoft.Web.Administration.dll, which is not present on Windows Server 2003. The program checks for the os and does not reference the dll if the os is 2003. if(OSVersion == WindowsServer2003) //do the job without referencing the Microsoft.Web.Administration.<br> else if(OSVersion == WindowsServer2008) //reference the Microsoft.Web.Administration.dll file.<br> When I tested this program on Windows Server 2003, an error occured telling me it couldn't locate the Microsoft.Web.Administration.dll. But when I separated the if-else block into 2 different methods as below, and the error did not occur. if(OSVersion == WindowsServer2003) //do the job without referencing the Microsoft.Web.Administration.<br> else if(OSVersion == WindowsServer2008) //DoIt2008Style(); So I wanted to know about reference file loading time in more detail. could you point me to some resources?

  • Download file using java apache commons?

    - by Kyle
    How can I use the library to download a file and print out bytes saved? I tried using import static org.apache.commons.io.FileUtils.copyURLToFile; public static void Download() { URL dl = null; File fl = null; try { fl = new File(System.getProperty("user.home").replace("\\", "/") + "/Desktop/Screenshots.zip"); dl = new URL("http://ds-forums.com/kyle-tests/uploads/Screenshots.zip"); copyURLToFile(dl, fl); } catch (Exception e) { System.out.println(e); } } but I cannot display bytes or a progress bar. Which method should I use?

  • WxWidgets custom events

    - by Klaus
    Hello, I'm trying to use a custom event in my WxWidgets C++ application, like described here. In the constructor of my wxApp: Connect(wxID_ANY, wxCommandEventHandler(APP::OnMyEvent)); Then the function that should catch the event: void APP::OnMyEvent(wxCommandEvent& event) { exit(0); //testing } Finally, to test it: wxCommandEvent MyEvent(wxEVT_COMMAND_BUTTON_CLICKED); wxPostEvent(this, MyEvent); I launch the thing...but it seems that the event is not posted or not caught. Does someone understand this behaviour ?

  • Flex Builder 3 executing old source codes

    - by Gorro
    I'm facing this problem again and again, but can't find any solution (except mine, which is not as a good one I guess). Don't know why, sometimes Flex Builder executes old source codes after making changes. While debugging I see how it steps through a source (e.g. changing local variables) which does not exist (even if I delete all that block or function). My way to solve that is to delete the project (backing up the source codes of course) and create a new one, add the backed up sources to the project and rebuild. It starts to work as it should work, but this way is not as comfortable, especially if sources are on a remote machine and you need to configure .net back-end. Anyone knows how to solve?

  • Bypassing Browser popup blocking when automatic session timout occurs

    - by Joseph
    Hi all, Please help regarding the following issue. I have enabled the "Block popup" option in browser. We are doing a session validation using a background ajax call to check the session is active or not. If the session is not active for a desired interval a popup window will come for notification. Now comming to the problem . since the session notification popup is comming automatically without any client interaction, This popup is blocked by the browser. But if a client clicks anyother popup window in the form that popup window will not be blocked by the browser.

  • NET Framework Validation Library

    - by Kane
    As I see it most applications have a requirement for some form of validation and a number of fantastic free offerings are available (I.E., Fluent Validation, Validation Block, Spring, Castle Windsor, etc). My question is why does the .NET Framework not include any inbuilt validation libraries? I am aware the .NET Framework allows a developer the ability to build their own validation libraries/methods/etc. and anything provided as part of the .NET Framework would not always meet everyone’s needs. But surely something could have been included? ASP.NET has a minimal set of validators but these have not really been extended since .NET 2.0 was released.

  • "Ambiguous template specialization" problem

    - by Setien
    I'm currently porting a heap of code that has previously only been compiled with Visual Studio 2008. In this code, there's an arrangement like this: template <typename T> T convert( const char * s ) { // slow catch-all std::istringstream is( s ); T ret; is >> ret; return ret; } template <> inline int convert<int>( const char * s ) { return (int)atoi( s ); } Generally, there are a lot of specializations of the templated function with different return types that are invoked like this: int i = convert<int>( szInt ); The problem is, that these template specializations result in "Ambiguous template specialization". If it was something besides the return type that differentiated these function specializations, I could obviously just use overloads, but that's not an option. How do I solve this without having to change all the places the convert functions are called?

  • Compiling a class using Java code using process

    - by Noona
    I have this piece of code that compiles a class called tspClassName, when I compile using this code: Process compileProc = null; try { compileProc = Runtime.getRuntime().exec("javac -classpath ." + File.separator + "src" + File.separator + File.separator + "generated." + tspClassName + ".java -d ." + File.separator + "bin"); // catch exception if (compileProc.exitValue() != 0) { System.out.println("Compile exit status: " + compileProc.exitValue()); System.err.println("Compile error:" + compileProc.getErrorStream()); it outputs this: "Compile exit status: 2 Compile error:java.io.FileInputStream@17182c1" The class tspClassName.java compiles without errors otherwise, so I am guessing it has to do with the path,and in my eclipse project, the tspClassName.java resides in package homework4.generated inside src, is there something wrong with the path that I use in the code? thanks

  • Ruby on Rails - Send JavaScript to view

    - by Eef
    Hey, I am creating a website in Ruby on Rails. I have a controller action that renders a view like so: def show time_left = Time.now.to_i - 3.hours.to_i @character = current_user.characters.find(params[:id]) respond_to do |format| format.html # show.html.erb format.xml { render :xml => @character } end end This is fine as it renders the show.html.erb as I like. I would like however to somehow pass time_left to the view as a Javascript variable as this value is use by a countdown JQuery plugin. I could put a javascript block on the page in the HTML and print a instance variable out like so: <script type="javascript"> $('#countdown').countdown('<%= @time_left =>')</script> But I would like to keep all my JS in a external file and off the page could anyone give some advice on how to implement this? Cheers Eef

  • Error using MVCContrib TestHelper

    - by Brian McCord
    While trying to implement the second answer to a previous question, I am receiving an error. I have implemented the methods just as the post shows, and the first three work properly. The fourth one (HomeController_Delete_Action_Handler_Should_Redirect_If_Model_Successfully_Delete) gives this error: Could not find a parameter named 'controller' in the result's Values collection. If I change the code to: actual .AssertActionRedirect() .ToAction("Index"); it works properly, but I don't like the "magic string" in there and prefer to use the lambda method that the other poster used. My controller method looks like this: [HttpPost] public ActionResult Delete(State model) { try { if( model == null ) { return View( model ); } _stateService.Delete( model ); return RedirectToAction("Index"); } catch { return View( model ); } } What am I doing wrong?

  • ASP.NET and IsNew on the page level

    - by tyndall
    Never seen this before in ASP.NET development. I'm trying to refactor out 40 single-page ASP.NET pages to code-behind style. What does this code do? // Validate required parameters (if "new", then nothing is required) if (!this.IsNew()) { if (string.IsNullOrEmpty(_billId)) { responseErrorNo = 4; Utils.SendError(respErrNum); } } Its on a single-page design ASP.NET page in the block in the Page_Load method. On a code-behind page this code ( .IsNew) is not recognized. What am I missing here? Is there an MSDN page on IsNew of the "page"?

  • How to Stop Current Playing Song When using one thread with JLayer?

    - by mcnemesis
    I recently used a solution to the one-thread-at-a-time problem whe using Jlayer to play mp3 songs in Java. But this solution by Kaleb Brasee didn't hint at how you could stop the player, i.e how could one then call player.close()? Kaleb's code was: Executor executor = Executors.newSingleThreadExecutor(); executor.execute(new Runnable() { public void run() { /* do something */ } }); and this is the code I put in run() if(player != null) player.close(); try{ player = new Player(new FileInputStream(musicD.getPath())); player.play(); }catch(Exception e){} The problem is that much as this solves the problem of keeping the gui active while the music plays (in only one other thread -- what i'd wanted), I can't start playing another song :-( What could I do?

  • How to log C++ exception if running outside debugger, otherwise rethrow

    - by Stefan Monov
    I wanna do something like this: int main() { try { runApp(); } catch(std::exception const& ex) { if(runningInDebugger()) throw; // let the IDE show me what went wrong else displayMsgBox("Something went wrong! " + ex.what()); } } Needs to work at least in VS2008 but the more debuggers it supports, the better. I want it to check for a debugger at runtime. I don't want to do "#ifdef NDEBUG", because I prefer not to do release builds at all (can't be bothered). So what should I use as a "runningInDebugger()" check?

  • JQuery response is null but actual response is not

    - by Paul Petrick
    I'm using JQuery to make an Ajax call. I used a sniffer to catch the response text: {"error_code":0,"message":"SUCCESS","data":{"session_token":"3efd9dde-a839-4e91-9415-4c2f6cba5b7b"}} But the response returned on the success callback is null. Anyone got any ideas? (see jquery code below. Jquery code: $.ajax({ type: "GET", url: "http://184.72.58.99/matchaapi/API/User/Login", data: { email: emailval, password: pwordval, developer_key: devkey }, dataType: "json", cache: false, beforeSend: function(xhr) { xhr.setRequestHeader( "Content-Type", "application/json; charset=utf-8" ); }, success: function(resp) { alert(resp); $("#status p").html(resp.message); }});

  • Getting column index out of range, 0 < 1

    - by Natraj

EntityManager entityMgrObj = emf.getEntityManager(); entityMgrObj.clear(); Query query = entityMgrObj.createNativeQuery("select * from company_user where user_id = 1001); List<CompanyUserDO> companyUserDOObj = null; try { companyUserDOObj = query.getResultList(); } catch (Exception e) { System.out.println(e.getMessage()); } When the query.getResultList() executes I get "Column index out of range, 0 < 1" error. Can somebody let me know what is wrong in the above code?

  • Better way to write this Java code?

    - by Macha
    public void handleParsedCommand(String[] commandArr) { if(commandArr[0].equalsIgnoreCase("message")) { int target = Integer.parseInt(commandArr[1]); String message = commandArr[2]; MachatServer.sendMessage(target, this.conId, message); } else if(commandArr[0].equalsIgnoreCase("quit")) { // Tell the server to disconnect us. MachatServer.disconnect(conId); } else if(commandArr[0].equalsIgnoreCase("confirmconnect")) { // Blah blah and so on for another 10 types of command } else { try { out.write("Unknown: " + commandArr[0] + "\n"); } catch (IOException e) { System.out.println("Failed output warning of unknown command."); } } } I have this part of my server code for handling the types of messages. Each message contains the type in commandArr[0] and the parameters in the rest of commandArr[]. However, this current code, while working seems very unelegant. Is there a better way to handle it? (To the best of my knowledge, String values can't be used in switch statements, and even then, a switch statement would only be a small improvement.

  • adding numeric values of variable number of forms

    - by user306472
    I'm trying to use jquery to loop through a block of forms that contain numeric data and add it all up to be displayed in a form with id grand. I have the ability to dynamically add new forms, so the number of forms I'm looping through will change. Here's my jquery code I wrote that isn't working for whatever reason: $('#table').delegate('input#grand', 'focus', function(){ var grand = $(input.expend).map(function(){ return this.value; }); $(grand).each(function(){ var g = 0; g+= $(this); $('input#grand').val(g); }); });

  • Difference in select for update of ... in Oracle Database 10g and 11g

    - by sax
    Hi, I found out that Oracle Database 10g and 11g treat the following PL/SQL block differently (I am using scott schema for convenience): DECLARE v_ename bonus.ename%TYPE; BEGIN SELECT b.ename INTO v_ename FROM bonus b JOIN emp e ON b.ename = e.ename JOIN dept d ON d.deptno = e.deptno WHERE b.ename = 'Scott' FOR UPDATE OF b.ename; END; / While in 10g (10.2) this code ends successfully (well NO_DATA_FOUND exception is raised but that is expected), in 11g (11.2) it raises exception "column ambiguously defined". And that is definitely not expected. It seems like it does not take into account table alias because I found out that when I change the column in FOR UPDATE OF e.empno (also does not work) to e.mgr (which is unique) it starts working. So is this some error in 11g? Any thoughts?

  • Controlling CodeModel's code output formatting: putting lines between namespace declarations

    - by devoured elysium
    I'm making some experiments with Visual Studio's CodeModel. I tried creating a file with two namespaces in there through VS's Code Model: CodeModel codeModel = projItem.ContainingProject.CodeModel; codeModel.AddNamespace("Namespaces.FirstNamespace", "namespacestest.cs"); codeModel.AddNamespace("Namespaces.SecondNamespace", "namespacestest.cs"); the output of such code is: //file namespacestest.cs namespace Namespaces.FirstNamespace { } namespace Namespaces.SecondNamespace { } Which is almost what I'm looking for. The only catch here is that I'd like to control the spacing: having at least one line between the first and the second namespace. Does by chance anyone know of a way of achieving this? This is what I want: //file namespacestest.cs namespace Namespaces.FirstNamespace { } namespace Namespaces.SecondNamespace { } Thanks

  • Does this variable need to be declared volatile?

    - by titaniumdecoy
    Does the out variable in the MyThread class need to be declared volatile in this code or will the "volatility" of the stdout variable in the ThreadTest class carry over? import java.io.PrintStream; class MyThread implements Runnable { int id; PrintStream out; // should this be declared volatile? MyThread(int id, PrintStream out) { this.id = id; this.out = out; } public void run() { try { Thread.currentThread().sleep((int)(1000 * Math.random())); out.println("Thread " + id); } catch (InterruptedException e) { e.printStackTrace(); } } } public class ThreadTest { static volatile PrintStream stdout = System.out; public static void main(String[] args) { for (int i = 0; i < 10; i++) { new Thread(new MyThread(i, stdout)).start(); } } }
