• EMail Signing (Outlook) Using Smartcard Minidriver [Windows]

  - by Baget

  Hi I'm developing a Smart card Minidriver and I'm trying to Sign an Email using Outlook 2007. I have implemented all of the necessary functions in the minidriver. I'm able to create a "Smartcard User" certificate and save it and it's private key on the smartcard (using Microsoft Certificate Services via the Minidriver). When I try to sign an EMail via Outlook I'm getting Error Message (Internal Error), the last call to the minidriver is for ReadFile with "cmapfile" When I try to sign an EMail via Outlook with a difference non-smartcard certificate it's work fine. When I try to sign a Data using CryptoAPI (based on Windows SDK Sample) it's working fine. I'm using Windows 7. someone got any idea how to debug this issue? I tried to enable the CAPI2 eventlog, it don't give me any good information.

• Intercept a request to read a particular file and instead generate the apparent output of that file

  - by Mike Atkinson

  Sorry for the long and yet still somehow vague title! A friend of mine has a Flash Action script running on a LAMP server that currently reads an xml config file. He's asked me if it's possible to remove the xml file, and replace it somehow with a system (lets call it an 'auto xml generator') that intercepts the request to read that file and generates an output, so it appears to all intents and purposes as if the file still exists and contains the contents that has actually been returned from our auto xml generator Hours of Googling has failed to come up with any promising leads, can anyone offer any advice? Thanks very much! Mike

• Core Location Best Placement and User Interruption

  - by b.dot

  Hi All, My application uses Core Location in three different views. It's working perfectly. In my first view, I subclass the CLLocationManager and use protocol methods for location updates to my calling class. Before I install the framework and code in my other classes, I was wondering: Is the protocol method the best way? What happens to the Core Location execution if the user exits the view or quits the app while it's trying to get a location fix? Is the location task terminated with the GPS system turned off immediately? If the user simply switches to another view, is it OK to assume that I can start Core Location in the next view without regard to the last? Where should the first update location call be placed. Should the application delegate instantiate the CLLocation Manager class using protocol so that it can update any of the views chosen or should each class instantiate the manager. Any feedback would be appreciated. Thanks.

• Java servlet and UTF-8 problem

  - by Gabriele

  I have some problem with UTF-8. My client (realized in GWT) make a request to my servlet, with some parametres in the URL, as follow: http://localhost:8080/servlet?param=value When in the servlet I retrieve the URL, I have some problem with UTF-8 characters. I use this code: protected void service(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { request.setCharacterEncoding("UTF-8"); String reqUrl = request.getRequestURL().toString(); String queryString = request.getQueryString(); System.out.println("Request: "+reqUrl + "?" + queryString); ... So, if I call this url: http://localhost:8080/servlet?param=così the result is like this: Request: http://localhost:8080/servlet?param=cos%C3%AC What can I do to set up properly the character encoding?

• Generic HTTP Handler in ASP.Net

  - by Bruno Brant

  Hello all, I want to write a custom HTTP Handler in ASP.Net (I'm using C# currently) that filters all requests to, say, .aspx files, and then, depending on the page name that comes with the requests, I redirect the user to a page. So far, I've written a handler that filter "*", that is, everything. Let's say I receive a request for "Page.aspx", and want to send the user to "AnotherPage.aspx". So I call Redirect on that response and pass "AnotherPage.aspx" as the new page. The problem is that this will once more trigger my handler, which will do nothing. This will leave the user without any response. So, is there a way to send the request to the other handlers (cascade the message) once I've dealt with it? Thanks, Bruno

• Binding elements when modal window loads from AJAX (jQuery)

  - by thinkswan

  I'd like to set up a drag'n'drop list inside a modal window. The window's content is loaded via an AJAX call, so I believe I need to use jQuery's .live() method. Here is my current code: $('#cboxLoadedContent').live('load', function() { // Event for sortable page lists $('ul#pageList').sortable(); }); How can I set up bindings when the modal window loads? The modal window comes from the colorbox plugin. Note: I'm guessing that 'load' is not the right event to use, because if I throw a simple alert() in there, it doesn't even show up when the window loads.

• Protecting against transaction concurency (Transaction type; Transaction IsolationLevel)

  - by Vytas999

  Middle-tier component will execute the data access routines in application. The component will call several SQL Server stored procedures to perform database updates. All of these procedure calls run under the control of a single transaction. The code for the middle-tier will implement the following objects: SqlCommand comm = connection.CreateCommand(); SqlTransaction trans; How i must add code to component to specify the highest possible level of protection against such errors(two users try to update the same data concurrently).

• Can I have conditional construction of classes when using IoC.Resolve ?

  - by Corpsekicker

  I have a service class which has overloaded constructors. One constructor has 5 parameters and the other has 4. Before I call, var service = IoC.Resolve<IService>(); I want to do a test and based on the result of this test, resolve service using a specific constructor. In other words, bool testPassed = CheckCertainConditions(); if (testPassed) { //Resolve service using 5 paramater constructor } else { //Resolve service using 4 parameter constructor //If I use 5 parameter constructor under these conditions I will have epic fail. } Is there a way I can specify which one I want to use?

• JDBC resultset close

  - by KM

  I am doing profiling of my Java application and found some interesting statistics for a jdbc PreparedStatement call: Given below is the environment details: Database: Sybase SQL Anywhere 10.0.1 Driver: com.sybase.jdbc3.jdbc.SybDriver connection pool: c3p0 JRE: 1.6.0_05 The code in question is given below: try { ps = conn.prepareStatement(sql); ps.setDouble(...); rs = ps.executeQuery(); ...... return xyz; } finally { try { if (rs != null) rs.close(); if (ps != null) ps.close(); } catch (SQLException sqlEx) { } } From JProfiler stats, I find that this particular resultspace.close() statement alone takes a large amount of time. It varies from 25 ms to 320s while for other code blocks which are of identical in nature, i find that this takes close to 20 microseconds. Just to be sure, I ran this performance test multiple times and confirmed this data. I am puzzled by this behaviour - Thoughts?

• Use a "x-dom-event-stream" stream in javascript ?

  - by rnaud

  Hello, HTML5 draft contains an API called EventSource to stream data (notifications) trough javascript using only one server call. Looking it up, I found an exemple on Opera Labs of the javascript part : document.getElementsByTagName("event-source")[0] .addEventListener("server-time", eventHandler, false); function eventHandler(event) { // Alert time sent by the server alert(event.data); } and the server side part : <?php header("Content-Type: application/x-dom-event-stream"); while(true) { echo "Event: server-time\n"; $time = time(); echo "data: $time\n"; echo "\n"; flush(); sleep(3); } ?> But as of today, it seems only Opera has implemented the API, neither Chrome nor Safari have a working version (Am I wrong here ?) So my question is, is there any other way in javascript, maybe more complex, to use this one stream to get data ?

• Serialize WPF component using XamlWriter without default constructor

  - by mizipzor

  Ive found out that you can serialize a wpf component, in my example a FixedDocument, using the XamlWriter and a MemoryStream: FixedDocument doc = GetDocument(); MemoryStream stream = new MemoryStream(); XamlWriter.Save(doc, stream); And then to get it back: stream.Seek(0, SeekOrigin.Begin); FixedDocument result = (FixedDocument)XamlReader.Load(stream); return result; However, now I need to be able to serialize a DocumentPage as well. Which lacks a default constructor which makes the XamlReader.Load call throw an exception. Is there a way to serialize a wpf component without a default constructor?

• audioPlayerDidFinishPlaying not being called during scrolling UITableView

  - by Rob

  One of my views is a UITableView which acts as the delegate for an AVAudioPlayer and this table essentially plays sounds when you select a certain row with options to repeat the sound after its finished playing. However, I noticed that if I select a cell with repeat ON for a certain sound and then scroll through the UITableView to select a different sound, it will not call audioPlayerDidFinishPlaying (and therefore not repeat) until after scrolling has stopped. As soon as I stop scrolling, it repeats just fine. Or if I don't scroll at all, it repeats just fine. What could be happening during scrolling that the UITableView is no longer acting as the delegate and calling audioPlayerDidFinishPlaying? Any thoughts?

• Objective C message dispatch mechanism

  - by Dolphin

  I am just staring to play around with Objective C (writing toy iPhone apps) and I am curious about the underlying mechanism used to dispatch messages. I have a good understanding of how virtual functions in C++ are generally implemented and what the costs are relative to a static or non-virtual method call, but I don't have any background with Obj-C to know how messages are sent. Browsing around I found this loose benchmark and it mentions IMP cached messages being faster than virtual function calls, which are in turn faster than a standard message send. I am not trying to optimize anything, just get deeper understanding of how exactly the messages get dispatched. How are Obj-C messages dispatched? How do Instance Method Pointers get cached and can you (in general) tell by reading the code if a message will get cached? Are class methods essentially the same as a C function (or static class method in C++), or is there something more to them? I know some of these questions may be 'implementation dependent' but there is only one implementation that really counts.

• Simple way to return anonymous types (to make MVC using LINQ possible)

  - by BlueRaja The Green Unicorn

  I'd like to implement MVC while using LINQ (specifically, LINQ-to-entities). The way I would do this is have the Controller generate (or call something which generates) the result-set using LINQ, then return that to the View to display the data. The problem is, if I do: return (from o in myTable select o); All the columns are read from the database, even the ones (potentially dozens) I don't want. And - more importantly - I can't do something like this: return (from o in myTable select new { o.column }); because there is no way to make anonymous types type-safe! I know for sure there is no nice, clean way of doing this in 3.5 (this is not clean...), but what about 4.0? Is there anything planned, or even proposed? Without something like duck-typing-for-LINQ, or type-safe anonymous return values (it seems to me the compiler should certainly be capable of that), it appears to be nearly impossible to cleanly separate the Controller from the View.

• How do I debug a DLL from VS2008?

  - by GregH

  I have a program written in VB.Net (Visual Studio 2008) that uses a DLL written in Visual C++ by another developer. I'd like to be able to step in to the C++ code as my code makes calls to methods in the DLL. Since the DLL is it's own solution, I don't think it can be included in my solution/project. I tried putting the DLLs pdb file in the debug/bin directory with the rest of my build and pdb files. However, when I get to the point in stepping through my code, and it gets to the dll call, it just steps right over the dll code. Do I have to manually load symbols? Not sure what I'm doing wrong. Thanks.

• C# unit test code questions

  - by 5YrsLaterDBA

  We start use C# build-in unit test functionality. I have VisualStudio 2008 created unit test code for me. I have few question above the generated code. Following are code I copied from the generated file: #region Additional test attributes // //You can use the following additional attributes as you write your tests: // //Use ClassInitialize to run code before running the first test in the class //[ClassInitialize()] //public static void MyClassInitialize(TestContext testContext) //{ //} // //Use ClassCleanup to run code after all tests in a class have run //[ClassCleanup()] //public static void MyClassCleanup() //{ //} // //Use TestInitialize to run code before running each test //[TestInitialize()] //public void MyTestInitialize() //{ //} // //Use TestCleanup to run code after each test has run //[TestCleanup()] //public void MyTestCleanup() //{ //} // #endregion If I need the initialize and cleanup methods, do I need to remove those "My" from the method name when I enable them? //Use ClassInitialize to run code before running the first test in the class //[ClassInitialize()] //public static void MyClassInitialize(TestContext testContext) //{ //} Do I need to call the "MyClassInitialize" method somewhere before running the first test or it will be called automatically before other methods are called. Similar questions for other three methods, are they called automatically at right time frame?

• Get the ID of the Current Textbox using JQuery

  - by Aaron Salazar

  I have a form with 3 text boxes that all do the same thing. They each call the JQuery function below after each keypress. Since I have 3 textboxes that all do the same thing, I'd like this function to work for all three. How do I change this function so that it'll grab the textbox's ID that is currently being edited instead of just the one? $(function() { $('#DocId').live('keydown', function() { var styleValue = $(this).val(); $('#tableContent').load( '/CurReport/TableResults', { style: styleValue } ); }) }); Thank you, Aaron

• Communicating with the PC via USB connection in Android

  - by Danny Singh

  I'm fairly new to android programming and need some information for a 4th year forensics course project. Basically I am trying to create a suite of tools for live analysis of an android phone. I know how to get the information I need on the phone, but I was wondering if there was a way to communicate that information back to the PC? I want to be able to run a program from a PC, which, when the phone is docked, will allow the user to access information about the phone (ie currently running services/processes, bluetooth/wifi connections, etc). I have a bunch of methods that will run on the phone and get all the information, but I want to be able to call those methods from the PC, execute on the phone, then have the information sent back to the PC to display to the user instead of just displaying it on the phone. This is to leave as small a footprint on the phone as possible. Thanks a lot.

• How to Maintain per-Client State in a WCF Service?

  - by tbischel

  I've created a WCF service in which I would like it to maintain state between calls from the client. I figured the easiest way to do this was to add this attribute to the service: [ServiceBehavior(InstanceContextMode = InstanceContextMode.PerSession)] since this is supposed to keep a separate service alive for each client over the life of the client proxy (or timeout in the extreme case). I also added a test function that tracks a list of user inputs, and spits out a concatenated string with all the inputs over the life of the service. When I run this in the test client generated by visual studio, I find that the list I was using to hold past data is reset with each call. Is there something else I need to do to maintain state per session?

• file_get_contents() returns "failed to open stream" when used with Facebook access_token flow

  - by TMC

  file_get_contents() is returning "failed to open stream" when I call it on a Facebook oAuth access_token URL. Warning: file_get_contents(https://graph.facebook.com/oauth/access_token?client_id=XXXXX&redirect_uri=http://mydomain.com/fb/callback3.php&client_secret=xxxx&code=YYYY) [function.file-get-contents]: failed to open stream: No error in E:\\htdocs\fb\callback3.php on line 5 (I have removed ClientID, clientSecret and the oAuth Code). If I try to manually hit the Facebook access_token URL that my code is attempting to fetch, I get an actual payload returned in the browser: access_token=XYZ&expires=6508 (where XYZ is the access token) So for some reason, there is a problem with the access_token URL specifically when used with file_get_contents(). At first, I thought it was a security issue with my webhoster, but I have verified with phpinfo() that allow url open is indeed allowed. I have also tried this code and verified it works: $foo = file_get_contents('http://google.com'); echo $foo Anyone have any ideas why file_get_contents() is failing with the Facebook access_token URL?

• XML documentation to context sensitive help

  - by Yonas

  These days a number of commercial and open source tools have been developed for this purpose. However(unfortunately), non of them meet my requirement for specific problem I am dealing with. Currently, I am working on a project that exposes a different classes and functions to user as scripting interface. the user can use the objects from custom scripting interface and call methods to solve some specific problem. The problem I am facing is users of my classes need some sort of documentation in order to write their script efficiently. To address this problem am planing to use the compiler generated XML file to provide context sensitive help, which allows users to mouse over on any of the controls and corresponding methods from the GUI and read the reference documentation of the class/method. Now ... here are my questions: Can I get the sample source code? Can any one give me someone point me to some sort of best approach to address the problem?

• How to link a SQlite Extension Source File into Xcode for iPhone?

  - by crunchyt

  I use a statically linked library for Sqlite in an iPhone Xcode project. I am now trying to include a .C extension to Sqlite in this project. However, I am having trouble making the Sqlite in the build SEE the extension. The statically linked Sqlite library works fine. Also the .C extension works on my desktop, and builds fine as a statically linked library in Xcode. However, the custom functions it defines are missing when called. For example, I load the extension as so with no errors. SELECT load_extension('extension_name.so'); But when I try to call a function defined in the extension, I get this message DB Error: 1 "no such function: custom_function" Does anyone know much about linking a Sqlite extension into an Xcode project?

• How do I force one method to be executed before another method?

  - by RexOnRoids

  I've got 2 methods. One method starts playing an audio file (.mp3), the other method updates a UIToolBar to show a button (PLAY or PAUSE). These two methods are called in the following order: //Adds some UIBarButtonItems to a UIToolBar [self togglePlayer]; //Uses AVAudioPlayer [audioPlayer play]; I call the methods in the above order so that the (pause) button will be shown at the time the song starts playing. But, the problem is that the song starts playing first, and the UIToolBar remains unchanged for quite a while (from 2 to 5 secs) until the button is added and shown. What I want is for the button to be shown at the same time the song starts playing (i.e. NO DELAY). Is there any way to do this?

• Anything wrong with spamming GC.KeepAlive(KeyboardHookPointer)?

  - by Alex

  GC.KeepAlive() References the specified object, which makes it ineligible for garbage collection from the start of the current routine to the point where this method is called. Not really sure about what GC.KeepAlive does other than simply store a reference so the Garbage Collector doesn't collect the object. But does calling GC.KeepAlive() on an object permanently keep an object from being collected? Or do you have to re-call GC.KeepAlive() every so often (and if so, how often)? I want to keep my keyboard hook alive.
