Is that possible? string raw ="http://www.google.com/search?hl=en&q={0}&aq=f&oq=&aqi=n1g10"; string search = string.Format(raw, HttpUtility.UrlEncode(searchTerm)); HttpWebRequest request = (HttpWebRequest)WebRequest.Create(search); request.Proxy = prox; using (HttpWebResponse response = (HttpWebResponse)request.GetResponse()) { using (StreamReader reader = new StreamReader(response.GetResponseStream(), Encoding.ASCII)) { HtmlElementCollection html = reader.ReadToEnd(); browserA=reader.ReadToEnd(); this.Invoke(new EventHandler(IE1)); } }

  • Java singleton VO class implementing serializable, having default values using getter methods

    - by user309281
    Hi All I have a J2SE application having user threads running in a separate JVM outside JBOSS server. During startup, J2SE invokes a EJB inside jboss, by passing a new object(singleton) of simple JAVA VO class having getter/setter methods. {The VO class is a singleton and implements serialiable(as mandated by EJB)}. EJB receives the object, reads all db configuration and uses the setter methods of new object to set all the values. It then returns back this updated object back to J2SE in the same remote call. After J2SE receives the object(singleton/serializable), if i invoke getter methods, I could see only default values set during object creation before EJB call, and not the values set by the EJB. Kindly throw some light on, why the received object from EJB does not see any updated values and how to rectify this. I believe it got to do with object initialization during deserialization. And i tried overriding readResolve() in the VO class, but of no help. With Regards, Krishna

  • How can I dynamically inject code to event handlers in Delphi?

    - by mjustin
    For debugging / performance tests I would like to dynamically add logging code to all event handlers of components of a given type. For example, for all Dataset components located ona TDatamodule, I would like to add some code for the BeforeOpen and the AfterOpen event to store the start and end time and send a line to a logger with the elapsed time in the AfterOpen event. I would prefer to do this dynamically (no component subclassing), so that I can add this to all existing datamodules and forms with minimal effort only when needed. Iterating all components and filtering by their type is easy, but for the components which already have event handlers assigned, I need a way to store the existing event handlers, and assign a new modified event handler which first does the logging and then will invoke the original code which was already present. Is there a design pattern which can be applied, or even some example code which shows how to implement this in Delphi?

  • How to use OptionParse to allow only one flag

    - by dorelal
    There are only three ways to invoke install.sh ./install.sh ./install.sh --force ./install.sh -f I can write it easily. However I am trying to make use of OptionParse. This is what I have so far. def self.parse option = {} optparse = OptionParser.new do |opts| opts.banner = "Usage: ./install.sh [--force]" opts.on('-f', '--force', '') do |dir| option[:force] = true end end begin optparse.parse! rescue OptionParser::InvalidOption => e puts e end end How do I provide feedback to user in case user provides something other than -f or --force.

  • Call JavaScript function from Silverlight 4.0 application

    - by Raha
    I am trying to call a function from a Silverlight application. It should be a very simple task to do but so far I am not getting the result that I am looking for. This is my Silverlight code: private void button2_Click(object sender, RoutedEventArgs e) { HtmlPage.Window.Invoke("SayHello", new string[] { "Salut!" }); } And this is the JavaScript code : function SayHello(theid) { alert(eval(theid)); var divStatusDiv = document.getElementById("divStatus"); divStatusDiv.style.backgroundColor = "Red"; } The alert message always show "undefined" but when I press "OK" the colour of that DIV gets changed to Red as it should be. Why am I getting "Undefined" all the time ?

  • How to test silverlight behaviors using Rhino Mocks?

    - by Derek
    I have slightly adapted the custom behavior code that can be found here: http://www.reflectionit.nl/blog/default.aspx?guid=d81a8cf8-0345-48ee-bbde-84c2e3f21a25 that controls a MediaElement. I need to know how to go about testing this with Rhino Mocks e.g. how to instantiate a new ControlMediaElementAction in test code and then call the Invoke method etc. Doing something simple like this in test code: mMediaElementControlBehaviour = new ControlMediaElementAction (); gives me an exception "The type initializer for 'System.Windows.DependencyObject' throw an exception. Thinking it was the instantiation of the MediaElement, I tried this two lines of code: MediaElement mediaElementStub = MockRepository.GenerateStub(); this.Container.RegisterInstance(mediaElementStub); This gave the exception 'Can't create mocks of sealed classes' If someone can point me in the right direction, it would be apreciated. Silverlight 4, Rhino Mocks 3.5 Silverlight v2.0.50727 Thanks,

  • What is a right way to use servlets?

    - by vikp
    Hi, I'm studying EJB3. I have a session bean which provides services to create/update customer accounts. This session bean offers services on the lines of: public void addCustomer(Customer c); public void updateCustomer(Customer c); Ideally I'd like to have a single servlet: CustomerServlet and it would invoke the session beans that I have listed above. Problem is that I have two JSPs: UpdateAccount.jsp and CreateAccount.jsp. Both of these JSPs have a form with a method POST and action "CustomerServlet". How can I distinguish in a customer servlet which operation I should carry out: createAccount or updateAccount? I guess the alternative is to have a separate servlet for each operation... Thank you

  • JBoss classloading when 2 WARs have the same class

    - by Pacman
    I have a web applications A.war which has two servlets AServlet and BServlet. Both instantiate a helper class com.mycompany.Foo.class (this is my own class, not a third party library). Now I want to split the two servlets into two separate WARs: A.war will have only AServlet and a new B.war will have BServlet. AServlet will invoke BServlet via HTTP GET. Both WARs will have com.mycompany.Foo.class. I want to deploy both WARs on the same JBoss instance. The question is, will there be any classloading issues due to the same class being present in both WARs, and the WARs being deployed on the same JBoss instance?

  • C++/CLI Mixed Mode DLL Creation

    - by Adam Haile
    I've got a native C++ DLL that I would like to have a C++/CLI wrapper layer for. From what I understood, if you simple added a C++/CLI class to the project, VS would compile as mixed mode, but I was apparently wrong as VS doesn't seem to be even touching the managed code. So, given a pre-existing native code-base what exactly, step-by-step, do you need to do to create a mixed mode DLL, so that I can can link into that code from any .NET language? *I need to do this because my native code uses C++ classes that I cannot P/Invoke into.

  • Obtain Update Table Lock at start of Stored Procedure in SQL Server

    - by Jim Hurne
    I'm writing a SQL Server stored procedure in which I want to lock a table for update before executing the body of the stored procedure. I don't want to prevent other processes from reading the table, but I do want to prevent other processes updating the table. Here is my first attempt: CREATE PROCEDURE someProcedure BEGIN SET TRANSACTION ISOLATION LEVEL READ COMITTED BEGIN TRANSANCTION SELECT COUNT(*) FROM TheTable WITH (UPDLOCK, TABLOCK) -- Pause procedure so that we can view the locks with sp_lock WAITFOR DELAY '00:15' -- Do stuff COMMIT END When I execute the stored procedure, and invoke sp_lock, I see that the table is indeed locked. However, it's locked with an Exclusive lock instead of an update lock: spid | dbid | ObjId | IndId | Type | Resource | Mode | Status ------------------------------------------------------------------ 63 | 10 | 233208031 | 0 | TAB | | X | GRANT How can I get an update (U) lock instead?

  • How to check whether the form has any ShowDialog() forms open?

    - by kornelijepetak
    I have a form MainForm with several properties/methods that are accessed from another thread. At some point I might open a form AuxForm with ShowDialog() and then while that modal form is open, the other thread still modifies the MainForm's properties. This is all desired. In one of the methods accessed from another thread I need to execute some code, but only if the modal AuxForm is not open. Is there any way to check this (by using .NET WF Form properties) or I need to use a flag variable? NOTE: None of these properties/methods modify the controls (so no Invoke is required).

  • Deserialization on client side in Domain Service

    - by ankit
    I have 2 classes: Person and Contact. Person class has a property named ContactNumber which returns the Contact type, and this property is marked as a DataMember for serialization. I have marked Contact type as a DataContract. On the client side I am able to get the values, but when I try to insert a value and then do submit, I get the following exception: Failed to deserialize change-set.

  • Getting Raw XML From SOAPMessage in Java

    - by Daniel Lew
    I've set up a SOAP WebServiceProvider in JAX-WS, but I'm having trouble figuring out how to get the raw XML from a SOAPMessage (or any Node) object. Here's a sample of the code I've got right now, and where I'm trying to grab the XML: @WebServiceProvider(wsdlLocation="SoapService.wsdl") @ServiceMode(value=Service.Mode.MESSAGE) public class SoapProvider implements Provider<SOAPMessage> { public SOAPMessage invoke(SOAPMessage msg) { // How do I get the raw XML here? } } Is there a simple way to get the XML of the original request? If there's a way to get the raw XML by setting up a different type of Provider (such as Source), I'd be willing to do that, too.

  • How to debug a WCF Service with an HTTP Context?

    - by JL
    I need to debug a WCF service but it needs to have an HTTP Context. Currently I have a solution with a WCF service web site, when I click on debug it starts up and then fires up an html page that contains no test form. While the project is running I tried starting the wcftestclient manually, then provided the address of my service, it finds the service but when I invoke it, it bypasses the IIS layer (or development server), so the httpContext is null... What is the correct way to debug a WCF service through an IIS context?

  • Why is a menu item disabled when using SWTBot?

    - by reprogrammer
    I've written up a GUI test using SWTBot to test the Extract Method refactoring. I use editor.selectRange() to select a statement to extract into a method. But, when I run the unit test, the Extract Method refactoring menu item is disabled. Thus, SWTBot fails to invoke the refactoring. When we change org.eclipse.jdt.ui.actions.ExtractMethodAction so that the "Extract Method..." menu item is always enabled, our SWTBot passes. But, SWTBot should let us select the menu item without hacking the org.eclipse.jdt.ui plugin. The whole project containing the above unit test is available at github. I've also reported the problem on the Eclipse forum for SWTBot. But, we haven't received a solution from the forum.

  • Installing a condition handler in Common Lisp

    - by Paul Nathan
    The HTTP library Drakma on CLISP generates an error USOCKET:UNSUPPORTED due to a bug in Drakma+CLISP. However, it turns out that the CONTINUE restart seems to work fine. Therefore, I spent some time with CLtL and other references trying to determine how to write a restart handler. (defun http-request (url param) (handler-bind ((USOCKET:UNSUPPORTED #'(lambda (x) (invoke-restart 'continue))))) (drakma:http-request url :method :post :parameters param)) According to my best understanding, the above code should trap the error USOCKET:UNSUPPORTED. It doesn't; it seems to ignore the error binder. How do I fix this?

  • the callback sequence of viewDidAppear and viewDidDisappear between two view controllers

    - by olinYY
    As I know, there are at least two ways to present a UIViewController on another UIViewController, first is using presentModalViewController:animated: on UIViewController, another is using pushViewController:animated: on UINavigationController, it seems when 2 view controller changing their appearance, the invoke sequence of appear/disappear callbacks are different. Following is an example, A is a UINavigationController, and B is a normal view controller, the actual callback sequence are: (1) A using presentModalViewController:animated: to show B: [B viewWillAppear]; [A viewWillDisappear]; [B viewDidAppear]; [A viewDidDisappear]; (2) A using pushViewController:animated: to show B: [A viewWillDisappear]; [B viewWillAppear]; [A viewDidDisappear]; [B viewDidAppear]; So my question is that, are these different callback sequence stable, or there are no definite sequence we can rely on? If they are stable, is there any document mentions this behavior? Can anyone help? Thanks in advanced!
