UNIVERSITY OF CHAKWAL FACULTY OF COMPUTER SCIENCE AND INFORMATION TECHNOLOGY COMPUTER SCIENCE AND INFORMATION TECHNOLOGY DEPARTMENT Introduction to Information and Communication Technologies Lab Instructor: Engr. Samina Bilquees Lab Manual 3  Microsoft Word 2016 Statement Purpose: The objective of this lab is to cover all features of Microsoft Word 2016 Design and Layout Tab. The Design and layout tab is where you can change the appearance of the entire Word document. Resources required: 1. A desktop computer 2. Microsoft Office 2016 Microsoft Word 2016 Design Tab: 1 Document Formatting: THEMES The first section of the Design tab is Themes. Themes is a great feature if you are typing an elaborate document and want to use a variety of fonts and colors and then duplicating those fonts and colors on another document or throughout a long document. A document theme is a set of formatting choices that include a set of theme colors, a set of theme fonts that you can specify a heading and body text font, and a set of theme affects you can choose, lines and fill effects. Style Set: 2 You can save this document‟s current style set and use it in other documents by right-clicking and then clicking save. Theme Colors: Quickly change all the colors used in your document by picking a different color palette. This will update the colors available to you in the color picker along with any theme colors in your document. No matter what palette you choose, your document will look perfectly coordinated. 3 Theme Fonts: Quickly change the text in your document by picking a new font set. For this to work, your text must be formatted using the „body‟ and „heading‟ fonts. 4 Paragraph Spacing: Quickly change the line and paragraph spacing of your document. This option will change the spacing of your entire document including new paragraphs. You can choose between predefined values or specify your own. 5 Effects: Quickly change the general look of objects in your document. Each option uses various borders and visual effects, such as shading and shadow, to give your objects a different look. 6 Page Background Watermark To include a watermark on the page, such as „Confidential‟ or „Draft‟, select Watermark from the Page Background group and then select one of the pre-defined watermarks or Custom Watermark to specify the text you would like to see appear as a watermark on the page. Page Color Allows you to change the color of document's background. This includes solid colors and fill eff- ects (gradients, textures, patterns, and pictures). 7 Page Borders Allows you to add borders around your document. There are many choices that can be made for creating borders, such as using art, the line style, colors, the setting of it, the width, and more. 8 Example: Page Border with Art and Shading: 9 Layout Tab: Margins To set the margin for your document, click on Margins and then select from the list of pre- defined margins or click Custom Margins to enter your own margins. 10 Orientation To change the page orientation of your document, click on Orientation and then select Portrait or Landscape. Size To change the paper size, click on Size and then select from the list of pre-defined paper sizes or click More Paper Sizes to enter a customized size. 11 Columns To create columns within your document, click on Columns and then select from the list of pre- defined column types or click More Columns to enter a customized column style. 12 Example: 13  Breaks: Choose different ways to jump to the next "top" area. A Page Break, for example, will jump from your current position to the top of the next page; a Column Break will jump from your current position to the top of the next column. And so on. 14  Line Numbers: You can add numbers to the side of each line, if you wish.  Hyphenation: You can have the computer break words into parts and add hyphens, to make Justified or other-aligned text look more even. 15 By clicking on the dialog box button, you can get the Page Setup dialog box. Margins Tab: Change margins and orientation. 16 Paper Tab: Change paper size and printer tray options. Layout Tab: Set Header & Footer preferences. 17 Paragraph The Paragraph group will allow you to set indentations and line spacing for your document.  Indent: You can change only the left or right indents  Spacing: Add or remove extra spacing after paragraphs. Position You can set/arrange picture at any position of page. 18 Bring Forward and Send Backward  To move an object one step closer to the front of the stack, click the arrow next to Bring Forward, and then click Bring Forward.  To bring an object to the top of the stack, click the arrow next to Bring Forward, and then click Bring to Front.  To move an object one step down within the stack, click the arrow next to Send Backward, and then click Send Backward.  To move an object to the bottom of the stack, click the arrow next to Send Backward, and then click Send to Back. Selection Pane This tool helps you find graphic objects in your document and change their visibility and order. You can use the feature to hide, rename, reorder, and select graphics in your documents. Align, Group and Rotate Pictures Using this option, you can align pictures, you can treat them in group and you can also rotate them with your desired angles. 1- Insert images (You may do it from insert tab>shapes) 2- Select images 3- Click on align or group or rotate. 19  Lab Tasks: Marks: 10 A.

This is an important practical barrier for the advancement of research and innovation in this field, which is difficult to achieve without a sufficient testbed to try and evaluate the innovations. Artificial examples (i.e. built by the innovators themselves) hardly provide an objective basis for measuring the usefulness and performance of new proposals, not to mention the considerable cost implied in building the testbed, just for experimentation purposes. The semi-automatic generation of web services, from such a widespread commodity as are web applications, can help with this necessity, and is an interesting research problem by itself. Of course, the expected quality of automatically generated services should not be the same as that of manually defined ones, but we aim at achieving a sufficient quality for the services to be useful for a variety of purposes, where of course, if needed, the generated web services can be completed or refined by a programmer. Moreover, such a facility as we are proposing here can be helpful in the transition from the current World Wide Web of applications to a (Semantic) Web of services. The idea of the automatic generation of web services from web applications has already been addressed in former research works. Because of its relevance for our research, it is worth citing the work developed by Pham (2004), which already proposes the creation of web services from web applications. In Pham‟s proposal, web services are used only as gateways to web applications, so that any program can invoke programmatically the functionalities provided by web applications. When the generated web services are called, they translate their input parameters to HTTP parameters, send them to the application server, and wait for the response. Our work takes a step further from this, by recognizing or generating data types, finding associations of types with ontology concepts, if any, and automatically classifying the generated services. Overall, our research aims to push forward the goals undertaken by Pham et al towards the generation of semantically- enhanced web service descriptions. It is also interesting to cite the early work by Sahuguet et al (1999) in a similar direction. Although this work does not use an explicit notion of web service, since web service standards had not yet seen the light by that time, their approach is very similar to the one proposed by Pham. The main differences can be attributed to the status of the technology at the time of publication – while Pham uses web service languages and tools to build a gateway to web applications, Sahuguet et al. use non-standard descriptions (manually generated) and generate Java applications as a gateway to the functionality. The process flow of our approach to the generation of web services is shown in Figure 1. The input to the automatic generation system is the entry web page of an application. The page is parsed (“HTML parser” box in the figure) into a easier to process in-memory data structure, which is analyzed in order to produce a WSDL description (WSDL Generator module) for the service to be generated, plus some additional semantic descriptions (Semantics Generator module). An implementation of the WSDL service is automatically generated (Service Implementor module) and deployed into a web service support platform (Axis and Tomcat have been used). Once the service is deployed, it can be invoked from any web service client that adheres to the generated WSDL description. One such client is automatically generated for testing purposes. Calls to the generated web service (SOAP requests) are automatically deferred to the original web application (HTTP request) by the generated service implementation. The result (a web page source code) is returned to the service client (SOAP response). The steps enumerated above will be explained in more detail in each of the following subsections. More precisely, in section 2.1, we explain how WSDL descriptions are extracted from the web interface of applications. In section 2.2, the linkage 22 of web services with web application functionality, and the deployment of the service, are described. Then, in section 2.3, we show how the execution of the generated web services is managed. 23
