  • Is QtQuick.Controls available on Ubuntu 13.10

    - by javascript is future
    I was looking to do UI development in QML, and I really want it to look native. I found the QtQuick.Controls (http://qt-project.org/doc/qt-5.1/qtquickcontrols/qtquickcontrols-index.html), but when I try make a simple application, it tells me that QtQuick.Controls isn't installed. main.qml: import QtQuick 2.1 import QtQuick.Controls 1.0 Rectangle { height: 200 width: 200 } terminal: $ qmlscene main.qml file:///tmp/main.qml:2 module "QtQuick.Controls" is not installed Also, I downloaded the source from https://qt.gitorious.org/qt/qtquickcontrols/source/stable, ran qmake && make, but this returned the following output: cd src/ && ( test -e Makefile || /usr/lib/i386-linux-gnu/qt5/bin/qmake /tmp/qtquickcontrols/src/src.pro -o Makefile ) && make -f Makefile make[1]: Går til katalog '/tmp/qtquickcontrols/src' cd controls/ && ( test -e Makefile || /usr/lib/i386-linux-gnu/qt5/bin/qmake /tmp/qtquickcontrols/src/controls/controls.pro -o Makefile ) && make -f Makefile make[2]: Går til katalog '/tmp/qtquickcontrols/src/controls' g++ -c -g -O2 -fstack-protector --param=ssp-buffer-size=4 -Wformat -Werror=format-security -D_FORTIFY_SOURCE=2 -O2 -fvisibility=hidden -fvisibility-inlines-hidden -std=c++0x -fno-exceptions -Wall -W -D_REENTRANT -fPIC -DQT_NO_XKB -DQT_NO_EXCEPTIONS -D_LARGEFILE64_SOURCE -D_LARGEFILE_SOURCE -DQT_NO_DEBUG -DQT_PLUGIN -DQT_QUICK_LIB -DQT_QML_LIB -DQT_WIDGETS_LIB -DQT_NETWORK_LIB -DQT_GUI_LIB -DQT_CORE_LIB -I/usr/share/qt5/mkspecs/linux-g++ -I. -I/usr/include/qt5 -I/usr/include/qt5/QtQuick -I/usr/include/qt5/QtQml -I/usr/include/qt5/QtWidgets -I/usr/include/qt5/QtNetwork -I/usr/include/qt5/QtGui -I/usr/include/qt5/QtGui/5.1.1 -I/usr/include/qt5/QtGui/5.1.1/QtGui -I/usr/include/qt5/QtCore -I/usr/include/qt5/QtCore/5.1.1 -I/usr/include/qt5/QtCore/5.1.1/QtCore -I.moc/release-shared -o .obj/release-shared/qquickaction.o qquickaction.cpp qquickaction.cpp:49:39: fatal error: private/qguiapplication_p.h: No such file or directory #include <private/qguiapplication_p.h> ^ Is there some PPA I could use, or do I have to wait for Trusty to get out, before I can use native controls from Qt?

  • How to display Sharepoint Data in a Windows Forms Application

    - by Michael M. Bangoy
    In this post I'm going to demonstrate how to retrieve Sharepoint data and display it on a Windows Forms Application. 1. Open Visual Studio 2010 and create a new Project. 2. In the project template select Windows Forms Application. 3. In order to communicate with Sharepoint from a Windows Forms Application we need to add the 2 Sharepoint Client DLL located in c:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\ISAPI. 4. Select the Microsoft.Sharepoint.Client.dll and Microsoft.Sharepoint.Client.Runtime.dll. (Your solution should look like the one below) 5. Open the Form1 in design view and from the Toolbox menu Add a Button, TextBox, Label and DataGridView on the form. 6. Next double click on the Load Button, this will open the code view of the form. Add Using statement to reference the Sharepoint Client Library then create two method for the Load Site Title and LoadList. See below:   using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Security; using System.Windows.Forms; using SP = Microsoft.SharePoint.Client;   namespace ClientObjectModel {     public partial class Form1 : Form     {         // url of the Sharepoint site         const string _context = "theurlofthesharepointsite";         public Form1()         {             InitializeComponent();         }         private void Form1_Load(object sender, EventArgs e)         {                    }         private void getsitetitle()         {             SP.ClientContext context = new SP.ClientContext(_context);             SP.Web _site = context.Web;             context.Load(_site);             context.ExecuteQuery();             txttitle.Text = _site.Title;             context.Dispose();         }                 private void loadlist()         {             using (SP.ClientContext _clientcontext = new SP.ClientContext(_context))             {                 SP.Web _web = _clientcontext.Web;                 SP.ListCollection _lists = _clientcontext.Web.Lists;                 _clientcontext.Load(_lists);                 _clientcontext.ExecuteQuery();                 DataTable dt = new DataTable();                 DataColumn column;                 DataRow row;                 column = new DataColumn();                 column.DataType = Type.GetType("System.String");                 column.ColumnName = "List Title";                 dt.Columns.Add(column);                 foreach (SP.List listitem in _lists)                 {                     row = dt.NewRow();                     row["List Title"] = listitem.Title;                     dt.Rows.Add(row);                 }                 dataGridView1.DataSource = dt;             }                   }       private void cmdload_Click(object sender, EventArgs e)         {             getsitetitle();             loadlist();          }     } } 7. That’s it. Hit F5 to run the application then click the Load Button. Your screen should like the one below. Hope this helps.

  • SOA Starting Point: Methods for Service Identification and Definition

    As more and more companies start to incorporate a Service Oriented Architectural design approach into their existing enterprise systems, it creates the need for a standardized integration technology. One common technology used by companies is an Enterprise Service Bus (ESB). An ESB, as defined by Progress Software, connects and mediates all communications and interactions between services. In essence an ESB is a form of middleware that allows services to communicate with one another regardless of framework, environment, or location. With the emergence of ESB, a new emphasis is now being placed on approaches that can be used to determine what Web services should be built. In addition, what order should these services be built? In May 2011, SOA Magazine published an article that identified 10 common methods for identifying and defining services. SOA’s Ten Common Methods for Service Identification and Definition: Business Process Decomposition Business Functions Business Entity Objects Ownership and Responsibility Goal-Driven Component-Based Existing Supply (Bottom-Up) Front-Office Application Usage Analysis Infrastructure Non-Functional Requirements  Each of these methods provides various pros and cons in regards to their use within the design process. I personally feel that during a design process, multiple methodologies should be used in order to accurately define a design for a system or enterprise system. Personally, I like to create a custom cocktail derived from combining these methodologies in order to ensure that my design fits with the project’s and business’s needs while still following development standards and guidelines. Of these ten methods, I am particularly fond of Business Process Decomposition, Business Functions, Goal-Driven, Component-Based, and routinely use them in my designs.  Works Cited Hubbers, J.-W., Ligthart, A., & Terlouw , L.

  • How to go from Mainframe to the Cloud?

    - by Ruma Sanyal
    Running applications on IBM mainframes is expensive, complex, and hinders IT responsiveness. The high costs from frequent forced upgrades, long integration cycles, and complex operations infrastructures can only be alleviated by migrating away from a mainframe environment.  Further, data centers are planning for cloud enablement pinned on principles of operating at significantly lower cost, very low upfront investment, operating on commodity hardware and open, standards based systems, and decoupling of hardware, infrastructure software, and business applications. These operating principles are in direct contrast with the principles of operating businesses on mainframes. By utilizing technologies such as Oracle Tuxedo, Oracle Coherence, and Oracle GoldenGate, businesses are able to quickly and safely migrate away from their IBM mainframe environments. Further, running Oracle Tuxedo and Oracle Coherence on Oracle Exalogic, the first and only integrated cloud machine on the market, Oracle customers can not only run their applications on standards-based open systems, significantly cutting their time to market and costs, they can start their journey of cloud enabling their mainframe applications. Oracle Tuxedo re-hosting tools and techniques can provide automated migration coverage for more than 95% of mainframe application assets, at a fraction of the cost Oracle GoldenGate can migrate data from mainframe systems to open systems, eliminating risks associated with the data migration Oracle Coherence hosts transactional data in memory providing mainframe-like data performance and linear scalability Running Oracle software on top of Oracle Exalogic empowers customers to start their journey of cloud enabling their mainframe applications Join us in a series of events across the globe where you you'll learn how you can build your enterprise cloud and add tremendous value to your business. In addition, meet with Oracle experts and your peers to discuss best practices and see how successful organizations are lowering total cost of ownership and achieving rapid returns by moving to the cloud.

  • What are some practical uses of the "new" modifier in C# with respect to hiding?

    - by Joel Etherton
    A co-worker and I were looking at the behavior of the new keyword in C# as it applies to the concept of hiding. From the documentation: Use the new modifier to explicitly hide a member inherited from a base class. To hide an inherited member, declare it in the derived class using the same name, and modify it with the new modifier. We've read the documentation, and we understand what it basically does and how it does it. What we couldn't really get a handle on is why you would need to do it in the first place. The modifier has been there since 2003, and we've both been working with .Net for longer than that and it's never come up. When would this behavior be necessary in a practical sense (e.g.: as applied to a business case)? Is this a feature that has outlived its usefulness or is what it does simply uncommon enough in what we do (specifically we do web forms and MVC applications and some small factor WinForms and WPF)? In trying this keyword out and playing with it we found some behaviors that it allows that seem a little hazardous if misused. This sounds a little open-ended, but we're looking for a specific use case that can be applied to a business application that finds this particular tool useful.

  • Disaster Recovery Example

    Previously, I use to work for a small internet company that sells dental plans online. Our primary focus concerning disaster prevention and recovery is on our corporate website and private intranet site. We had a multiphase disaster recovery plan that includes data redundancy, load balancing, and off-site monitoring. Data redundancy is a key aspect of our disaster recovery plan. The first phase of this is to replicate our data to multiple database servers and schedule daily backups of the databases that are stored off site. The next phase is the file replication of data amongst our web servers that are also backed up daily by our collocation. In addition to the files located on the server, files are also stored locally on development machines, and again backed up using version control software. Load balancing is another key aspect of our disaster recovery plan. Load balancing offers many benefits for our system, better performance, load distribution and increased availability. With our servers behind a load balancer our system has the ability to accept multiple requests simultaneously because the load is split between multiple servers. Plus if one server is slow or experiencing a failure the traffic is diverted amongst the other servers connected to the load balancer allowing the server to get back online. The final key to our disaster recovery plan is off-site monitoring that notifies all IT staff of any outages or errors on the main website encountered by the monitor. Messages are sent by email, voicemail, and SMS. According to Disasterrecovery.org, disaster recovery planning is the way companies successfully manage crises with minimal cost and effort and maximum speed compared to others that are forced to make decision out of desperation when disasters occur. In addition Sun Guard stated in 2009 that the first step in disaster recovery planning is to analyze company risks and factor in fixed costs for things like hardware, software, staffing and utilities, as well as indirect costs, such as floor space, power protection, physical and information security, and management. Also availability requirements need to be determined per application and system as well as the strategies for recovery.

  • Business Forces: SOA Adoption

    The only constant in today’s business environment is change. Businesses that continuously foresee change and adapt quickly will gain market share and increased growth. In our ever growing global business environment change is driven by data in regards to collecting, maintaining, verifying and distributing data.  Companies today are made and broken over data. Would anyone still use Google if they did not have one of the most accurate search indexes on the internet? No, because their value is in their data and the quality of their data. Due to the increasing focus on data, companies have been adopting new methodologies for gaining more control over their data while attempting to reduce the costs of maintaining it. In addition, companies are also trying to reduce the time it takes to analyze data in regards to various market forces to foresee changes prior to them actually occurring.   Benefits of Adopting SOA Services can be maintained separately from other services and applications so that a change in one service will only affect itself and client services or applications. The advent of services allows for system functionality to be distributed across a network or multiple networks. The costs associated with maintain business functionality is much higher in standard application development over SOA due to the fact that one Services can be maintained and shared to other applications instead of multiple instances of business functionality being duplicated via hard coding in to several applications. When multiple applications use a single service for a specific business function then the all of the data being processed will be consistent in terms of quality and accuracy through the applications. Disadvantages of Adopting SOA Increased initial costs and timelines are associated with SOA due to the fact that services need to be created as well as applications need to be modified to call the services In order for an SOA project to be successful the project must obtain company and management support in order to gain the proper exposure, funding, and attention. If SOA is new to a company they must also support the proper training in order for the project to be designed, and implemented correctly. References: Tews, R. (2007).

  • Necessary Infrastructure for large project with many components communicating through IPCs

    - by jluzwick
    I have a fairly in depth question which probably doesn't have an exact answer. As a software engineer, I am usually tasked with working on a program or project with minimal understanding of how other components or programs in the project interact with each other. When one program fails in a sea of multiple components and processes, what infrastructure elements are necessary to ensure that the problem can be accurately tracked to the violating application? More specifically, what infrastructure elements should be necessary for this large project and which are optional but very helpful. One such example I can think of is some form of a common logging infrastructure that allows for a developer or tester to easily browse through a log that contains numerous components for messages that might allude to the culprit program along with a "trail" of what happened before the issue occurred. I'm thinking of something similar to Androids alogcat tool. These necessary infrastructure elements should be language-agnostic. While these elements should be understood by all engineers on the team in question, which elements should be understood at great detail by the technical system engineers and what should the individual software engineers be responsible for adding to their tools to allow for such infrastructures to take hold? Please feel free to ask for clarification if something does not make sense as I understand this question is very broad and needs some refinement. I will refine as necessary from the answers and comments I receive. Thanks for any help!

  • How to keep a window from overlapping into another workspace?

    - by user1477
    It's annoying to me how if a window is even a couple pixels off the right edge of my screen, when I switch to that right workspace, the system thinks that the window is there. The unity launcher bar gets hidden because of it and switching to that window keeps you on the current workspace where you can't even see the window cause it's only a couple pixels. KDE seems to do this much better where when you switch to another workspace, the window just isn't there. But well I don't want KDE. Any way of getting that same behavior without the switch?

  • Securing an ASP.NET MVC 2 Application

    - by rajbk
    This post attempts to look at some of the methods that can be used to secure an ASP.NET MVC 2 Application called Northwind Traders Human Resources.  The sample code for the project is attached at the bottom of this post. We are going to use a slightly modified Northwind database. The screen capture from SQL server management studio shows the change. I added a new column called Salary, inserted some random salaries for the employees and then turned off AllowNulls.   The reporting relationship for Northwind Employees is shown below.   The requirements for our application are as follows: Employees can see their LastName, FirstName, Title, Address and Salary Employees are allowed to edit only their Address information Employees can see the LastName, FirstName, Title, Address and Salary of their immediate reports Employees cannot see records of non immediate reports.  Employees are allowed to edit only the Salary and Title information of their immediate reports. Employees are not allowed to edit the Address of an immediate report Employees should be authenticated into the system. Employees by default get the “Employee” role. If a user has direct reports, they will also get assigned a “Manager” role. We use a very basic empId/pwd scheme of EmployeeID (1-9) and password test$1. You should never do this in an actual application. The application should protect from Cross Site Request Forgery (CSRF). For example, Michael could trick Steven, who is already logged on to the HR website, to load a page which contains a malicious request. where without Steven’s knowledge, a form on the site posts information back to the Northwind HR website using Steven’s credentials. Michael could use this technique to give himself a raise :-) UI Notes The layout of our app looks like so: When Nancy (EmpID 1) signs on, she sees the default page with her details and is allowed to edit her address. If Nancy attempts to view the record of employee Andrew who has an employeeID of 2 (Employees/Edit/2), she will get a “Not Authorized” error page. When Andrew (EmpID 2) signs on, he can edit the address field of his record and change the title and salary of employees that directly report to him. Implementation Notes All controllers inherit from a BaseController. The BaseController currently only has error handling code. When a user signs on, we check to see if they are in a Manager role. We then create a FormsAuthenticationTicket, encrypt it (including the roles that the employee belongs to) and add it to a cookie. private void SetAuthenticationCookie(int employeeID, List<string> roles) { HttpCookiesSection cookieSection = (HttpCookiesSection) ConfigurationManager.GetSection("system.web/httpCookies"); AuthenticationSection authenticationSection = (AuthenticationSection) ConfigurationManager.GetSection("system.web/authentication"); FormsAuthenticationTicket authTicket = new FormsAuthenticationTicket( 1, employeeID.ToString(), DateTime.Now, DateTime.Now.AddMinutes(authenticationSection.Forms.Timeout.TotalMinutes), false, string.Join("|", roles.ToArray())); String encryptedTicket = FormsAuthentication.Encrypt(authTicket); HttpCookie authCookie = new HttpCookie(FormsAuthentication.FormsCookieName, encryptedTicket); if (cookieSection.RequireSSL || authenticationSection.Forms.RequireSSL) { authCookie.Secure = true; } HttpContext.Current.Response.Cookies.Add(authCookie); } We read this cookie back in Global.asax and set the Context.User to be a new GenericPrincipal with the roles we assigned earlier. protected void Application_AuthenticateRequest(Object sender, EventArgs e){ if (Context.User != null) { string cookieName = FormsAuthentication.FormsCookieName; HttpCookie authCookie = Context.Request.Cookies[cookieName]; if (authCookie == null) return; FormsAuthenticationTicket authTicket = FormsAuthentication.Decrypt(authCookie.Value); string[] roles = authTicket.UserData.Split(new char[] { '|' }); FormsIdentity fi = (FormsIdentity)(Context.User.Identity); Context.User = new System.Security.Principal.GenericPrincipal(fi, roles); }} We ensure that a user has permissions to view a record by creating a custom attribute AuthorizeToViewID that inherits from ActionFilterAttribute. public class AuthorizeToViewIDAttribute : ActionFilterAttribute{ IEmployeeRepository employeeRepository = new EmployeeRepository(); public override void OnActionExecuting(ActionExecutingContext filterContext) { if (filterContext.ActionParameters.ContainsKey("id") && filterContext.ActionParameters["id"] != null) { if (employeeRepository.IsAuthorizedToView((int)filterContext.ActionParameters["id"])) { return; } } throw new UnauthorizedAccessException("The record does not exist or you do not have permission to access it"); }} We add the AuthorizeToView attribute to any Action method that requires authorization. [HttpPost][Authorize(Order = 1)]//To prevent CSRF[ValidateAntiForgeryToken(Salt = Globals.EditSalt, Order = 2)]//See AuthorizeToViewIDAttribute class[AuthorizeToViewID(Order = 3)] [ActionName("Edit")]public ActionResult Update(int id){ var employeeToEdit = employeeRepository.GetEmployee(id); if (employeeToEdit != null) { //Employees can edit only their address //A manager can edit the title and salary of their subordinate string[] whiteList = (employeeToEdit.IsSubordinate) ? new string[] { "Title", "Salary" } : new string[] { "Address" }; if (TryUpdateModel(employeeToEdit, whiteList)) { employeeRepository.Save(employeeToEdit); return RedirectToAction("Details", new { id = id }); } else { ModelState.AddModelError("", "Please correct the following errors."); } } return View(employeeToEdit);} The Authorize attribute is added to ensure that only authorized users can execute that Action. We use the TryUpdateModel with a white list to ensure that (a) an employee is able to edit only their Address and (b) that a manager is able to edit only the Title and Salary of a subordinate. This works in conjunction with the AuthorizeToViewIDAttribute. The ValidateAntiForgeryToken attribute is added (with a salt) to avoid CSRF. The Order on the attributes specify the order in which the attributes are executed. The Edit View uses the AntiForgeryToken helper to render the hidden token: ......<% using (Html.BeginForm()) {%><%=Html.AntiForgeryToken(NorthwindHR.Models.Globals.EditSalt)%><%= Html.ValidationSummary(true, "Please correct the errors and try again.") %><div class="editor-label"> <%= Html.LabelFor(model => model.LastName) %></div><div class="editor-field">...... The application uses View specific models for ease of model binding. public class EmployeeViewModel{ public int EmployeeID; [Required] [DisplayName("Last Name")] public string LastName { get; set; } [Required] [DisplayName("First Name")] public string FirstName { get; set; } [Required] [DisplayName("Title")] public string Title { get; set; } [Required] [DisplayName("Address")] public string Address { get; set; } [Required] [DisplayName("Salary")] [Range(500, double.MaxValue)] public decimal Salary { get; set; } public bool IsSubordinate { get; set; }} To help with displaying readonly/editable fields, we use a helper method. //Simple extension method to display a TextboxFor or DisplayFor based on the isEditable variablepublic static MvcHtmlString TextBoxOrLabelFor<TModel, TProperty>(this HtmlHelper<TModel> htmlHelper, Expression<Func<TModel, TProperty>> expression, bool isEditable){ if (isEditable) { return htmlHelper.TextBoxFor(expression); } else { return htmlHelper.DisplayFor(expression); }} The helper method is used in the view like so: <%=Html.TextBoxOrLabelFor(model => model.Title, Model.IsSubordinate)%> As mentioned in this post, there is a much easier way to update properties on an object. Download Demo Project VS 2008, ASP.NET MVC 2 RTM Remember to change the connectionString to point to your Northwind DB NorthwindHR.zip Feedback and bugs are always welcome :-)

  • Database users in the Oracle Utilities Application Framework

    - by Anthony Shorten
    I mentioned the product database users fleetingly in the last blog post and they deserve a better mention. This applies to all versions of the Oracle Utilities Application Framework. The Oracle Utilities Application Framework uses up to three users initially as part of the base operations of the product. The type of database supported (the framework supports Oracle, IBM DB2 and Microsoft SQL Server) dictates the number of users used and their permissions. For publishing brevity I will outline what is available for the Oracle database and, in summary, mention where it differs for the other database supported. For Oracle database customers we ship three distinct database users: Administration User (SPLADM or CISADM by default) - This is the database user that actually owns the schema. This user is not used by the product to do any DML (Data Manipulation Language) SQL other than that is necessary for maintenance of the database. This database user performs all the DCL (Data Control Language) and DDL (Data Definition Language) against the database. It is typically reserved for Database Administration use only. Product Read Write User (SPLUSER or CISUSER by default) - This is the database user used by the product itself to execute DML (Data Manipulation Language) statements against the schema owned by the Administration user. This user has the appropriate read and write permission to objects within the schema owned by the Administration user. For databases such as DB2 and SQL Server we may not create this user but use other DCL (Data Control Language) statements and facilities to simulate this user. Product Read User (SPLREAD or CISREAD by default) - This is the database that has read only permission to the schema owned by the Administration user. It is used for reporting or any part of the product or interface that requires read permissions to the database (for example, products that have ConfigLab and Archiving use this user for remote access). For databases such as DB2 and SQL Server we may not create this user but use other DCL (Data Control Language) statements and facilities to simulate this user. You may notice the words by default in the list above. The values supplied with the installer are the default and can be changed to what the site standard or implementation wants to use (as long as they conform to the standards supported by the underlying database). You can even create multiples of each within the same database and pointing to same schema. To manage the permissions for the users, there is a utility provided with the installation (oragensec (Oracle), db2gensec (DB2) or msqlgensec (SQL Server)) that generates the security definitions for the above users. That can be executed a number of times for each schema to give users appropriate permissions. For example, it is possible to define more than one read/write User to access the database. This is a common technique used by implementations to have a different user per access mode (to separate online and batch). In fact you can also allocate additional security (such as resource profiles in Oracle) to limit the impact of specific users at the database. To facilitate users and permissions, in Oracle for example, we create a CISREAD role (read only role) and a CISUSER role (read write role) that can be allocated to the appropriate database user. When the security permissions utility, oragensec in this case, is executed it uses the role to determine the permissions. To give you a case study, my underpowered laptop has multiple installations on it of multiple products but I have one database. I create a different schema for each product and each version (with my own naming convention to help me manage the databases). I create individual users on each schema and run oragensec to maintain the permissions for each appropriately. It works fine as long I have setup the userids appropriately. This means: Creating the users with the appropriate roles. I use the common CISUSER and CISREAD role across versions and across Oracle Utilities Application Framework products. Just remember to associate the CISUSER role with the database user you want to use for read/write operations and the CISREAD role with the user you wish to use for the read only operations. The role is treated as a tag to indicate the oragensec utility which appropriate permissions to assign to the user. The utilities for the other database types essentially do the same, obviously using the technology available within those databases. Run oragensec against the read write user and read only user against the appropriate administration user (I will abbreviate the user to ADM user). This ensures the right permissions are allocated to the right users for the right products. To help me there, I use the same prefix on the user name for the same product. For example, my Oracle Utilities Application Framework V4 environment has the administration user set to FW4ADM and the associated FW4USER and FW4READ as the users for the product to use. For my MWM environment I used MWMADM for the administration user and MWMUSER and MWMREAD for my associated users. You get the picture. When I run oragensec (once for each ADM user), I know what other users to associate with it. Remember to rerun oragensec against the users if I run upgrades, service packs or database based single fixes. This assures that the users are in synchronization with the ADM user. As a side note, for those who do not understand the difference between DML, DCL and DDL: DDL (Data Definition Language) - These are SQL statements that define the database schema and the structures within. SQL Statements such as CREATE and DROP are examples of DDL SQL statements. DCL (Data Control Language) - These are the SQL statements that define the database level permissions to DDL maintained objects within the database. SQL Statements such as GRANT and REVOKE are examples of DCL SQL statements. DML (Database Manipulation Language) - These are SQL statements that alter the data within the tables. SQL Statements such as SELECT, INSERT, UPDATE and DELETE are examples of DML SQL statements. Hope this has clarified the database user support. Remember in Oracle Utilities Application Framework V4 we enhanced this by also supporting CLIENT_IDENTIFIER to allow the database to still use the administration user for the main processing but make the database session more traceable.

  • Packaging Swing apps with integrated JavaFX content

    - by igor
    JavaFX provides a lot of interesting capabilities for developing rich client applications in Java, but what if you are working on an existing Swing application and you want to take advantage of these new features?  Maybe you want to use one or two controls like the LineChart or a MediaView.  Maybe you want to embed a large Scene Graph as an initial step in porting your application to FX.  A hybrid Swing/FX application might just be the answer. Developing a hybrid Swing + JavaFX application is not terribly difficult, but until recently the deployment of hybrid applications has not simple as a "pure" JavaFX application.  The existing tools focused on packaging FX Applications, or Swing applications - they did not account for hybrid applications. But with JavaFX 2.2 the tools include support for this hybrid application use case.  Solution  In JavaFX 2.2 we extended the packaging ant tasks to greatly simplify deploying hybrid applications.  You now use the same deployment approach as you would for pure JavaFX applications.  Just bundle your main application jar with the fx:jar ant task and then generate html/jnlp files using fx:deploy.  The only difference is setting toolkit attribute for the fx:application tag as shown below: <fx:application id="swingFXApp" mainClass="${main.class}" toolkit="swing"/>  The value of ${main.class} in the example above is your application class which has a main method.  It does not need to extend JavaFX Application class. The resulting package provides support for the same set of execution modes as a package for a JavaFX application, although the packages which are created are not identical to the packages created for a pure FX application.  You will see two JNLP files generated in the case of a hybrid application - one for use from Swing applet and another for the webstart launch.  Note that these improvements do not alter the set of features available to Swing applications. The packaging tools just make it easier to use the advanced features of JavaFX in your Swing application. The same limits still apply, for example a Swing application can not use JavaFX Preloaders and code changes are necessary to support HTML splash screens. Why should I use the JavaFX ant tasks for packaging my Swing application?  While using FX packaging tool for a Swing application may seem like a mismatch at face value, there are some really good reasons to use this approach.  The primary justification for our packaging tools is to simplify the creation of your application artifacts, and to reduce manual errors.  Plus, no one should have to write JNLP by hand. Some specific benefits include: Your application jar will include a launcher program.  This improves your standalone launch by: checking for the JavaFX runtime guiding the user through any necessary installations setting the system proxy for Java The ant tasks will generate JNLP and HTML files for your swing app: avoids learning unnecessary details about JNLP, and eliminates the error-prone hand editing of JNLP files simplifies using advanced features like embedding JNLP and signing jars as BLOBs to improve launch performance.you can also embed the signing certificate details to improve the user's experience  allows the use of web page templates to inject the generated code directly into your actual web page instead of being forced to copy/paste the generated code snippets. What about native packing? Absolutely!  The very same ant task can generate a native bundle for a Swing application with JavaFX content.  Try running one of these sample native bundles for the "SwingInterop" FX example: exe and dmg.   I also used another feature on these examples: a click-through license agreement for .exe installers and OS X DMG drag installers. Small Caveat This packaging procedure is optimized around using the JavaFX packaging tools for your entire Swing application.  If you are trying to embed JavaFX content into existing project (with an existing build/packing process) then you may need to experiment in order to find the best way to integrate the JavaFX packaging steps into your existing build procedure. As long as you can use ant in your build process this should be a workable approach. It some cases solution could be less than ideal. For example, you need to use fx:jar to package your main jar file in order to produce a double-clickable jar or a native bundle.  The jar will be created from scratch, but you may already be creating the main jar file with a custom manifest.  This may lead to some redundant steps in your build process.  Hopefully the benefits will outweigh the problems. This is an area of ongoing development for the team, and we will continue to refine and improve both the tools and the process. Please share your experiences and suggestions with us.  You can comment here on the blog or file issues to JIRA. Sample code Here is the full ant code used to package SwingInterop.  You can grab latest JavaFX samples and try it yourself:  <target name="-post-jar"> <taskdef resource="com/sun/javafx/tools/ant/antlib.xml" uri="javafx:com.sun.javafx.tools.ant" classpath="${javafx.tools.ant.jar}"/> <!-- Mark application as Swing-based --> <fx:application id="swingFXApp" mainClass="${main.class}" toolkit="swing"/> <!-- Create doubleclickable jar file with embedded launcher --> <fx:jar destfile="${dist.jar}"> <fileset dir="${build.classes.dir}"/> <fx:application refid="swingFXApp" name="SwingInterop"/> <manifest> <attribute name="Implementation-Vendor" value="${application.vendor}"/> <attribute name="Implementation-Title" value="${application.title}"/> <attribute name="Implementation-Version" value="1.0"/> </manifest> </fx:jar> <!-- sign application jar. Use new self signed certificate --> <delete file="${build.dir}/test.keystore"/> <genkey alias="TestAlias" storepass="xyz123" keystore="${build.dir}/test.keystore" dname="CN=Samples, OU=JavaFX Dev, O=Oracle, C=US"/> <fx:signjar keystore="${build.dir}/test.keystore" alias="TestAlias" storepass="xyz123"> <fileset file="${dist.jar}"/> </fx:signjar> <!-- generate JNLPs, HTML and native bundles --> <fx:deploy width="960" height="720" includeDT="true" nativeBundles="all" outdir="${basedir}/${dist.dir}" embedJNLP="true" outfile="${application.title}"> <fx:application refId="swingFXApp"/> <fx:resources> <fx:fileset dir="${basedir}/${dist.dir}" includes="SwingInterop.jar"/> </fx:resources> <fx:permissions/> <info title="Sample app: ${application.title}" vendor="${application.vendor}"/> </fx:deploy> </target>

  • How do I connect to SDF on a Mobile device from desktop application?

    - by pitprog
    C# WinForms .Net 3.5 to SQL CE 3.5 on Mobile 6.1 Device I'd like to make a connection from a desktop application to a SDF database on my Windows Mobile device while it's connected via ActiveSync. Visual Studio lets me create a Data Connection to my device. The connections tests OK and I can view the data in the database using Visual Studio. I then create a form and try to fill a DataGridView. When I run the program I get an error that the path to the data base is not valid. How am I supposed to specify the Mobile device path in the connection string? In my App.Config, I've tried variations on the path, but none of them work: connectionString="Data Source=Mobile Device\Program Files\SqlCeViaActiveSync\Orders.sdf" connectionString="Data Source=\Mobile Device\Program Files\SqlCeViaActiveSync\Orders.sdf" connectionString="Data Source=Program Files\SqlCeViaActiveSync\Orders.sdf" connectionString="Data Source=\Program Files\SqlCeViaActiveSync\Orders.sdf" The full connection string section looks like this: <connectionStrings> <add name="SqlCeViaActiveSync.Properties.Settings.OrdersConnectionString" connectionString="Data Source=Mobile Device\Program Files\SqlCeViaActiveSync\Orders.sdf" providerName="Microsoft.SqlServerCe.Client.3.5" /> </connectionStrings> Also, I did make a reference to Microsoft.SqlServerCe.Client, as I found a few articles that mentioned it was necessary. Can anyone point me to some recent articles/samples or let me know what I'm doing wrong? Thanks!

  • How can I use System.Web.Caching.Cache in a Console application?

    - by Ron Klein
    Context: .Net 3.5, C# I'd like to have caching mechanism in my Console application. Instead of re-inventing the wheel, I'd like to use System.Web.Caching.Cache (and that's a final decision, I can't use other caching framework, don't ask why). However, it looks like System.Web.Caching.Cache is supposed to run only in a valid HTTP context. My very simple snippet looks like this: using System; using System.Web.Caching; using System.Web; Cache c = new Cache(); try { c.Insert("a", 123); } catch (Exception ex) { Console.WriteLine("cannot insert to cache, exception:"); Console.WriteLine(ex); } and the result is: cannot insert to cache, exception: System.NullReferenceException: Object reference not set to an instance of an object. at System.Web.Caching.Cache.Insert(String key, Object value) at MyClass.RunSnippet() So obviously, I'm doing something wrong here. Any ideas? Update: +1 to most answers, getting the cache via static methods is the correct usage, namely HttpRuntime.Cache and HttpContext.Current.Cache. Thank you all!

  • When to use SOAP over REST

    So, how does REST based services differ from SOAP based services, and when should you use SOAP? Representational State Transfer (REST) implements the standard HTTP/HTTPS as an interface allowing clients to obtain access to resources based on requested URIs. An example of a URI may look like this http://mydomain.com/service/method?parameter=var1&parameter=var2. It is important to note that REST based services are stateless because http/https is natively stateless. One of the many benefits for implementing HTTP/HTTPS as an interface is can be found in caching. Caching can be done on a web service much like caching is done on requested web pages. Caching allows for reduced web server processing and increased response times because content is already processed and stored for immediate access. Typical actions performed by REST based services include generic CRUD (Create, Read, Update, and Delete) operations and operations that do not require state. Simple Object Access Protocol (SOAP) on the other hand uses a generic interface in order to transport messages. Unlike REST, SOAP can use HTTP/HTTPS, SMTP, JMS, or any other standard transport protocols. Furthermore, SOAP utilizes XML in the following ways: Define a message Defines how a message is to be processed Defines the encoding of a message Lays out procedure calls and responses As REST aligns more with a Resource View, SOAP aligns more with a Method View in that business logic is exposed as methods typically through SOAP web service because they can retain state. In addition, SOAP requests are not cached therefore every request will be processed by the server. As stated before Soap does retain state and this gives it a special advantage over REST for services that need to preform transactions where multiple calls to a service are need in order to complete a task. Additionally, SOAP is more ideal for enterprise level services that implement standard exchange formats in the form of contracts due to the fact that REST does not currently support this. A real world example of where SOAP is preferred over REST can be seen in the banking industry where money is transferred from one account to another. SOAP would allow a bank to perform a transaction on an account and if the transaction failed, SOAP would automatically retry the transaction ensuring that the request was completed. Unfortunately, with REST, failed service calls must be handled manually by the requesting application. References: Francia, S. (2010). SOAP vs. REST.

  • Current State EA: Focus on the Integration!!!

    - by Eric A. Stephens
    A recent project has me at the front end of a large implementation effort covering multiple software components. In addition to the challenges of integrating 15-20 separate and new software components there is the challenge of integrating the portfolio into an existing environment. Like other clients I've worked with and other environments I've worked in for many years, this is typical. The applications are undocumented and under patched leading to a mystery for any architect leading change.  We can boil down most architecture development methodologies (ADM) into first understanding the current/baseline state and then envisioning one or more future states. Many pundits emphasize the need to focus on the future/target states. I agree since enterprise architecture (EA) is about where you are going and not so much where you have been. But to be effective in the future, I contend some focused time needs to be spent on the current state. And specifically on the integration. Integration is always the difficult part of a project (I might put it more coarsely at a cocktail party). While I don't have a case study, my anecdotal experience suggests poorly integrated application portfolios tend to cost more to operate and create entropy when trying to respond to new changes and opportunities. In the aforementioned project, I was able to get one of our EAs assigned to focus on just integration almost immediately. While we're still early in the process, this EA is uncovering all sorts of information that will greatly assist our future state planning for this solution. This information is driving early decision making that we anticipate will accelerate our efforts moving forward. #next_pages_container { width: 5px; hight: 5px; position: absolute; top: -100px; left: -100px; z-index: 2147483647 !important; } #next_pages_container { width: 5px; hight: 5px; position: absolute; top: -100px; left: -100px; z-index: 2147483647 !important; } #next_pages_container { width: 5px; hight: 5px; position: absolute; top: -100px; left: -100px; z-index: 2147483647 !important; } #next_pages_container { width: 5px; hight: 5px; position: absolute; top: -100px; left: -100px; z-index: 2147483647 !important; }
