Envisioning the Solution

  • A solution concept is developed based on the existing business strategy. A developing team creates the solution concept on the basis of the business requirements and scope of the solution.
  • A project team identifies and understands the current business process in order to incorporate it in the proposed or new system.
  • During the Envisioning phase of the business project, the project team evaluates the current business situation. The team analyzes the difference between the current and expected business situation. A gap analysis is performed to identify a path towards the desired state of a business. The team also identifies and outlines the scope of the project.
  • A team identifies basic solution concept during the Envisioning phase.
  • A feasibility study determines and documents a project’s viability. The analysis of the feasibility study identifies whether a particular business concept can be realized as a scalable design.
  • During the Envisioning phase, various tasks are identified that address the goals and constraints of the project. During this phase, the project team determines the objectives of the solution by identifying business problems or opportunities.
  • A team analyzes business feasibility of a solution during the Envisioning phase.
  • The project scope is the number and complexity of tasks to be performed by a software solution. The scope comprises the overall project requirements and incorporates the constraints imposed on the project by resources, time, and other limiting factors.
  • Pass Microsoft .NET Certification in first attempt.

  • Project scope defines what will or will not be included in a project. Therefore, the project scope is the number and complexity of tasks to be performed by a software solution.
  • A team prepares the functional specification that will contain the scope of the solution. The project scope is the number and complexity of tasks to be performed by a software solution.
  • A developer plans and creates modules in order to define scope components in a project.
  • A project team identifies and analyzes the current and expected business system of an organization.
  • The project team identifies a set of initial risks during the Envisioning phase. The best technique to manage a risk is to identify all the potential risks with high priority level and to prevent them by following a good mitigation and prevention strategy.
  • During the solution development, greatest potential risks of an organization are identified.
  • A project team monitors the status of high-priority risks of an organization. The team identifies a set of initial risks during the Envisioning phase. This set of risks is continuously updated at the later phases of the project.
  • A team should identify the biggest threat that can occur within the organization. It should also try to control and mitigate the threat to the organization.
  • Risk Management is a decision-making process that involves the organization, users, and the project team. It deals with the uncertainties that might occur during the application development. This ensures that all the vital assets and resources of the organization are safeguarded.
  • A team identifies business risks of an organization.

Developing applications that use system types and collections

  • Use the CausesValidation property of the ImageButton class to set a value to indicate whether validation is performed on a Web server control when an ImageButton control is clicked.
  • Installation packages are created for deploying a Web application by using a Web Setup project. A merge module project is used for components to be added to the application.
  • Use the Web Setup project and Deployment project to create installation packages for the deployment of Web-based applications such as XML Web services, Web applications etc., to a Web server.
  • Use a RequiredFieldValidator control to check whether or not an input control contains a value.
  • Use a RegularExpressionValidator control to check whether or not the value entered into a form field matches the pattern specified by a regular expression.
  • Use the validation error messages to be displayed on a Web page in a message box by setting the ShowMessageBox property of the ValidationSummary control to true. By setting the ValidationSummary property of the ValidationSummary control to false, the validation summary will not be displayed on the Web page.
  • Create and sort an array of data using the System namespace.

Creating User Services

  • The SessionID property of the HttpSessionState class identifies an active ASP.NET session by using a unique session ID.
  • The @ Import directive is used to explicitly import a namespace into an ASP.NET application.
  • The @ Implements directive is used to implement a specified .Net Framework interface in a Web page.
  • The CodeBehind attribute of the @ Page directive specifies the name of the compiled file that contains the class associated with the page.
  • The ErrorPage attribute of the @ Page directive is used to set the URL if an unhandled exception occurs. Sam can set this target to the home page.
  • The Language attribute of the @ Page directive specifies the language used while compiling the inline rendering and code declaration blocks.
  • The Inherits attribute of the @ Page directive specifies a code-behind class for the page to inherit. It can be any class that is derived from the Page class.
  • Public variables and objects can be accessed from all other procedures and functions in all the modules in the same project.
  • The public class Manager : HeadOfDept declaration will create a class named Manager, which implements the HeadOfDept interface.

Creating User Services

  • The identity object of the IIdentity interface is used during the authentication process, when a user’s identity is verified. It contains information about a user who is being validated, such as username and password.
  • The principal object of the IPrincipal interface is used during the authentication process, when the application determines the data that can be accessed by a user and code to be executed. It contains information about a user’s identity, such as username and password, as well as information about a user’s role, such as manager or associate.
  • The correct sequence of the classes of the System.Windows.Forms namespace in descending order is as follows:
    1. Control
    2. ScrollableControl
    3. ContainerControl
    4. Forms
  • The MinimumSize property of the Form class is used to get or set the minimum size up to which a form can be resized.
