  • How to connect to a WCF service using IP of the host machine where the service is hosted?

    - by Kumar
    I have a secured WCF service (https://<MachineName>:sslport/services) self hosted in a machine. Different instances of same service are deployed in differnt machines. From a client app, I am able to connect to theses services through code, i.e. using ChannelFactory() with the same endpoint address. But if I try to access the service using the endpoint address as https://<ipAddress>:sslport/services replacing machines name with machine IP address, I am getting some error stating "could not establish trust relationship". I know this is an error caused by SSL certificate that it could not establish a trust relationship. Are there any settings or any possibilities to make this work?

  • How to set up Google DFP (DoubleClick for Publishers) for a site?

    - by Manoj Kumar
    I have a website and I have an AdSense account as well. I have integrated AdSense and ads are also getting displayed (480 x 60). Somewhere I read that I can manage the ads that are being shown in my website (480 x 60) and filter out the ads on a CPM/CPC basis. NOTE: I don't have any ads to be displayed on other's websites. I just want to show other's ads on my website. Now, can I use Google DFP to manage the ads? I mean is Google DFP useful for me to filter the ads and get me more revenue?

  • Which tools helps to start Ubuntu GUI when boot?

    - by Vimal Kumar
    I am on the way to create a Live CD from scratch. I used Virtual Box for this purpose. I installed Ubuntu base from ubuntumini.iso and installed gnome-shell. And installed Remastersys and created a backup.iso. Burned in a CD and boot from a PC. It end in CLI. Not lead to GUI. I tried the same ISO in VirtualBox. But it work properly there. I think I missed some packages which help to start GUI. Can you help me to identify the packages missed to include in the CD?

  • Oracle Virtualization Friday Spotlight - November 8, 2013

    - by Monica Kumar
    Hands-on Private Cloud Simulator In One Hour Submitted by: Doan Nguyen, Senior Principal Product Marketing Director My aeronautics instructor used to say, "you can’t appreciate flying until you take flight." To clarify, this is not about gearing up in a flying squirrel suit and hopping off a cliff (topic for another blog!) but rather about flying an airplane. The idea is to get hands-on with the controls at the cockpit and experience flight before you actually fly a real plane. After the initial 40 hours of flight time, the concept sank in and it really made sense.This concept is what inspired our technical experts to put together the hands-on lab for a private cloud deployment and management self-service model. Yes, we are comparing the lab to a flight simulator! Let’s look at the parallels: To get trained to fly, starting in the simulator gets you off the ground quicker. There is no need to have a real plane to begin with. In a hands-on lab, there is no need for a real server, with networking and real storage installed. All you need is your laptop The simulator is pre-configured, pre-flight check done. Similarly, in a hands-on lab, Oracle VM and Oracle Enterprise Manager are pre-configured and assembled using Oracle VM VirtualBox as the container. Software installations are not needed. After time spent training at the controls, you can really appreciate the practical experience of flying. Along the same lines, the hands-on lab is a guided learning path, without the encumbrances of hardware, software installation, so you can learn about cloud deployment and management.  However, unlike the simulator training, your time investment with the lab is only about an hour and not 40 hours! This hands-on lab takes you through private cloud deployment and management using Oracle VM and  Oracle Enterprise Manager Cloud Control 12c in an Infrastructure as a service IaaS model. You will first configure the IaaS cloud as the cloud administrator and then deploy guest virtual machines (VMs) as a self-service user. Then you are ready to take flight into the cloud! Why not step into the cockpit now!

  • How do I get Catalyst 11.10 with ATI Radeon Mobility HD 5470 working on an HP DV7?

    - by S Kumar
    I have a HP DV7 with a HD 5470 512M card. Installation of the Catalyst 11.10 is repeatedly failing on a fresh install of Ubuntu 11.10. Catalyst 11.8 proprietary drivers were working well with Ubuntu 11.04. I have tried installing directly from the .run and generating the distribution specific packages. Nothing has worked. After installation which goes through successfully, the system hangs on reboot after the flashing dots. I have to replace the /etc/X11/xorg.conf to get the X working. I have followed instructions as per the http://wiki.cchtml.com/index.php/Main_Page wiki. Request for support to ATI/AMD gives the response that this model is unsupported on Linux by HP :). Updated 14-Nov I have reverted back to the open source drivers which work well enough for me.

  • Testing web applications written in java

    - by Vinoth Kumar
    How do you test the web applications (both server side and client side code)? The testing method has to work irrespective of the framework used (struts, spring web mvc) etc. I am using Java for the server side code, Javascript and HTML for the client side code. This is the sample test case of what I am talking about: 1. When you click on a link, the pop up opens. 2. Change some value in the pop up (say a drop down value) and it gets saved in the DB. 3. Click the popup again, you get the changed values. Can we simulate this kind of thing using unit test cases? Is JUnit enough for this?

  • Object of type 'customObject' cannot be converted to type 'customObject'.

    - by Phani Kumar PV
    i am receiving the follwing error when i am invoking a custom object "Object of type 'customObject' cannot be converted to type 'customObject'." Following is the scenario when i am getting the error i am invoking a method in a dll dynamically. Load an assembly CreateInstance.... calling MethodInfo.Invoke() passing int, string as a parameter for my method is working fine = No exceptions are thrown. But if I try and pass a one of my own custom class objects as a parameter, then I get an ArgumentException exception, and it is not either an ArgumentOutOfRangeException or ArgumentNullException. "Object of type 'customObject' cannot be converted to type 'customObject'." I am doing this in a web application. The class file containing the method is in a different proj . also the custom object is a sepearte class in the same file. there is no such thing called a static aseembly in my code. I am trying to invoke a webmethod dynamically. this webmethod is having the customObject type as an input parameter. So when i invoke the webmethod i am dynamically creating the proxy assembly and all. From the same assembly i am trying to create an instance of the cusotm object assinging the values to its properties and then passing this object as a parameter and invoking the method. everything is dynamic and nothing is created static.. :( add reference is not used. Following is a sample code i tried to create it public static object CallWebService(string webServiceAsmxUrl, string serviceName, string methodName, object[] args) { System.Net.WebClient client = new System.Net.WebClient(); //-Connect To the web service using (System.IO.Stream stream = client.OpenRead(webServiceAsmxUrl + "?wsdl")) { //--Now read the WSDL file describing a service. ServiceDescription description = ServiceDescription.Read(stream); ///// LOAD THE DOM ///////// //--Initialize a service description importer. ServiceDescriptionImporter importer = new ServiceDescriptionImporter(); importer.ProtocolName = "Soap12"; // Use SOAP 1.2. importer.AddServiceDescription(description, null, null); //--Generate a proxy client. importer.Style = ServiceDescriptionImportStyle.Client; //--Generate properties to represent primitive values. importer.CodeGenerationOptions = System.Xml.Serialization.CodeGenerationOptions.GenerateProperties; //--Initialize a Code-DOM tree into which we will import the service. CodeNamespace nmspace = new CodeNamespace(); CodeCompileUnit unit1 = new CodeCompileUnit(); unit1.Namespaces.Add(nmspace); //--Import the service into the Code-DOM tree. This creates proxy code //--that uses the service. ServiceDescriptionImportWarnings warning = importer.Import(nmspace, unit1); if (warning == 0) //--If zero then we are good to go { //--Generate the proxy code CodeDomProvider provider1 = CodeDomProvider.CreateProvider("CSharp"); //--Compile the assembly proxy with the appropriate references string[] assemblyReferences = new string[5] { "System.dll", "System.Web.Services.dll", "System.Web.dll", "System.Xml.dll", "System.Data.dll" }; CompilerParameters parms = new CompilerParameters(assemblyReferences); CompilerResults results = provider1.CompileAssemblyFromDom(parms, unit1); //-Check For Errors if (results.Errors.Count > 0) { StringBuilder sb = new StringBuilder(); foreach (CompilerError oops in results.Errors) { sb.AppendLine("========Compiler error============"); sb.AppendLine(oops.ErrorText); } throw new System.ApplicationException("Compile Error Occured calling webservice. " + sb.ToString()); } //--Finally, Invoke the web service method Type foundType = null; Type[] types = results.CompiledAssembly.GetTypes(); foreach (Type type in types) { if (type.BaseType == typeof(System.Web.Services.Protocols.SoapHttpClientProtocol)) { Console.WriteLine(type.ToString()); foundType = type; } } object wsvcClass = results.CompiledAssembly.CreateInstance(foundType.ToString()); MethodInfo mi = wsvcClass.GetType().GetMethod(methodName); return mi.Invoke(wsvcClass, args); } else { return null; } } } I cant find anything static being done by me. any help is greatly appreciated.

  • Query on MVVM pattern in WPF?

    - by Ashish Ashu
    I am implementing a MVVM pattern in my WPF application. My application main window is divided into four parts: Main Menu On the Top Outlook Navigation Control on the Left. A List View on the Middle. Another List view on the bottom. The Navigation control shows different setting (configuration) controls in the Tab items. All the four above are user controls which are placed in the main window. And corresponding to each user control there is separate view model which is bounded with a view model in the XAML of each control, however the model class remain the same between all the view model. And a MainWindow has a seperate View Model which is also bounded with a view model in the XAML of each control. Please help me out in framing a design in which each view models of all the controls above will interact with each other. Please let me know if my question is not clear to you!!

  • DataBinding a dictionary to a combobox in WPF.

    - by Ashish Ashu
    I have a Dictionary which is binded to a combobox. I have used dictionary to provide spaces in enum. public enum Option {Enter_Value, Select_Value}; Dictionary<Option,string> Options; <ComboBox x:Name="optionComboBox" SelectionChanged="optionComboBox_SelectionChanged" SelectedValuePath="Key" DisplayMemberPath="Value" SelectedItem="{Binding Path = SelectedOption}" ItemsSource="{Binding Path = Options}" /> This works fine. My queries: 1. I am not able to set the initial value to a combo box. In above XAML snippet the line SelectedItem="{Binding Path = SelectedOption}" is not working. I have declared SelectOption in my viewmodel. This is of type string and I have intialized this string value in my view model as below: SelectedOption = Options[Options.Enter_Value].ToString(); 2. I want if user selects Options.Enter_Value from the combo box , the combo box becomes editable and user can enter the numeric value in it. If user selects the second option Options.Select_Value then a dialog is poped up which allows user to select the predifined values. And the combo box becomes read only and shows the selected value. Please Help!!

  • Question on MVVM pattern on WPF ?

    - by Ashish Ashu
    I have a user control let say UC1 . This user control have viewmodel UC1_vm. In the usercontrol UC1 I have a canvas in which drawing curve logic is implemented. This drawing curve logic is based on the data points property in the view model ( UC1_vm). The data points property inside the view model change with different condition. The generation of data points is written in the View Model. I want to bind the data points property in the view model to the draw curve logic inside the User control (view). I want whenever the data point property is changed in the view model , the canvas calls the draw curve method. Can I set the set any property of canvas which when changed it calls the on paint logic auto matically? Please suggest me the approach of implementing this scenario!!

  • Home automation using Arduino / XMPP client for Arduino

    - by Ashish
    I am trying to setup a system for automating certain tasks in my home. I am thinking of a solution wherein a server side application would be able to send/receive commands/data to Arduino (attached with Arduino Ethernet Shield) via the web. Here the Arduino may both act as a sensor interface to the server application or command executor interface for the server app. E.g. (user story): The overhead water tank in my house has a water level sensor attached with Arduino (attached with Arduino Ethernet Shield). Another Arduino (attached with Arduino Ethernet Shield) is attached with a relay/latch. This relay/latch is then connected to a water pump. Now the server side application on the web is able to get/receive water level information from the Arduino on the water tank. Depending on the water level information received, the web application should send suitable signals/commands to Arduino on water pump to switch 'ON' or switch 'OFF' the water pump. Now for such a system to work across the web, I am thinking of using one of the type of solutions in order of my priority: Using XMPP for communication between server application and Arduino. Using HTTP polling. Using HTTP hanging GET. For solution number 1, I need to implement a XMPP client that would reside on Arduino. Is it possible to write a XMPP client small enough to reside on an Arduino? If yes what are the minimum possible XMPP client functionality that I need to write for Arduino, so that it would be able to contact XMPP servers solutions like GTalk, etc.? For solution number 2 and 3 I need guidance in implementation. Also which solution would be cost effective and easily extendable?
