  1. Clearly Visual Basic: Programming with Visual Basic 2008 Chapter 4 I Need a Tour Guide

  2. Objectives • Create a Visual Basic 2008 Windows application • Use the Label and PictureBox tools to add a control to a form • Set the properties of an object • Save a solution Clearly Visual Basic: Programming with Visual Basic 2008

  3. Objectives (continued) • Size and align objects using the Format menu • Lock the controls on a form • Start and end an application • Close and open an existing solution Clearly Visual Basic: Programming with Visual Basic 2008

  4. OK, the Algorithm is Correct. What’s Next? • User interface • What appears on the screen and with which you interact while using a program • Integrated development environment (IDE) • Contains the tools and features you need to create, run, and test your programs Clearly Visual Basic: Programming with Visual Basic 2008

  5. Clearly Visual Basic: Programming with Visual Basic 2008

  6. Creating a Visual Basic Windows Application • Windows applications in Visual Basic • Composed of solutions, projects, and files • Solution • Can contain several projects • Project • Container that stores files associated with project Clearly Visual Basic: Programming with Visual Basic 2008

  7. My Wizard Quick Start Create a folder in C:\users\yourName\  called VBBefore you create your first application click on TOOLS- OPTIONSGo to Projects and solutionsVisual Studio Project Locations:  C:\users\you\VB                   User Templates:    C:\users\you\VB                   Item Templates:    C:\users\you\VB                    Check the following:                       Always show Error list Item in Solution Explorer                       Track Active Item in Solution Explorer                       Always show Solution                       Save New Projects when created Create a new VB Window ApplicationName it My Wizard ProjectPin the Control Toolbar and Properties Window (Properties window is Alphabetic)Name the Form1 Text property:  Wizard Application Clearly Visual Basic: Programming with Visual Basic 2008

  10. So Many Windows • You will find it easier to work in the IDE if: • You either close or auto-hide the windows you are not currently using • Auto Hide button • Toggle button: clicking it once activates it; clicking it again deactivates it Clearly Visual Basic: Programming with Visual Basic 2008

  11. Clearly Visual Basic: Programming with Visual Basic 2008

  12. Creating the User Interface • Windows Form Designer window • Where you create (or design) your application’s user interface • Form • The foundation for the user interface in a Windows application • Automatically includes a title bar that contains a default caption Clearly Visual Basic: Programming with Visual Basic 2008

  13. Clearly Visual Basic: Programming with Visual Basic 2008

  14. Creating the User Interface (continued) • Controls • Objects added to a form • Picture box • Displays an image on a form • Label controls • Display text that user is not allowed to edit while application is running Clearly Visual Basic: Programming with Visual Basic 2008

  15. Clearly Visual Basic: Programming with Visual Basic 2008

  16. Save, Save, Save • Good practice • Save current solution every 10 or 15 minutes • To save a solution • Click on File on the menu bar, then click Save All • Mini Quiz 1. A ____ control displays text that the user is NOT allowed to edit while an application is running 2. The _________ contains the toos you use to add objects to a form 3. GUI stands for _____________________ Clearly Visual Basic: Programming with Visual Basic 2008

  17. Whose Property Is It? • Properties • Determine object’s appearance and behavior • Name and current value of each property • Appear in the Properties window when the object is selected • Select the Form • Change the Text Property to Wizard Application • Change StartPosition to Center Screen • Change font to Segoe 9 Point Clearly Visual Basic: Programming with Visual Basic 2008

  18. Change the Properties Window to Alphabetical Clearly Visual Basic: Programming with Visual Basic 2008

  19. Whose Property Is It? (continued) • Exercises • Change the values assigned to some of the form’s properties • Change two properties of each label control • Change two properties of each picture box Clearly Visual Basic: Programming with Visual Basic 2008

  20. Using the Format Menu • Format menu • Provides several options for manipulating controls in the interface • Exercises • Make the PictureBox1 control the same size as the PictureBox2 control • Align the top borders of the two picture boxes • Click the task box and Choose Imagefind the images and import them to the screen • Wizard 1 –Size Mode = Stretch • Wizard 2- Size Mode = Auto Size Clearly Visual Basic: Programming with Visual Basic 2008

  21. Change Label1’s text property to Wizard 1 and Label2’s Text Property to Wizard 2Change the Location property of Wizard 1 to 40,212 and the location property of Wizard 2 to 175, 212 Clearly Visual Basic: Programming with Visual Basic 2008

  22. Lock Them Down • Locking the controls • Prevents them from being moved inadvertently as you work in the IDE • Unlock and then lock the controls • Right Click the Form and Choose Lock Controls Clearly Visual Basic: Programming with Visual Basic 2008

  23. Clearly Visual Basic: Programming with Visual Basic 2008

  24. OK, Let’s See the Interface in Action • You can start an application by: • Clicking Debug on the menu bar and then clicking Start Debugging or • You can simply press the F5 key on your keyboard Clearly Visual Basic: Programming with Visual Basic 2008

  25. Clearly Visual Basic: Programming with Visual Basic 2008

  26. Closing the Current Solution • To close a solution • Use the Close Solution option on the File menu • When you close a solution • All projects and files contained in the solution are also closed Clearly Visual Basic: Programming with Visual Basic 2008

  27. Opening an Existing Solution • To open an existing solution • Use the File menu or the Start Page • If a solution is already open in the IDE • It is closed before another solution is opened Clearly Visual Basic: Programming with Visual Basic 2008

  28. Exiting Visual Studio • To exit Visual Studio • Use either the Close button on its title bar or • The Exit option on the File menu Clearly Visual Basic: Programming with Visual Basic 2008

  29. Summary • Creating the user interface • Fourth step in the problem-solving process • Windows applications in Visual Basic • Composed of solutions, projects, and files • Label controls • Display text that user is not allowed to edit while an application is running Clearly Visual Basic: Programming with Visual Basic 2008

  30. Summary (continued) • Picture boxes • Used to display images on a form • Good practice to save a solution every 10 or 15 minutes • Form’s StartPosition property • Specifies the position of the form when it first appears on the screen Clearly Visual Basic: Programming with Visual Basic 2008

  31. Summary (continued) • Font property • Determines the type, style, and size of font used to display text on the form • Picture box control’s Image property • Specifies name of file containing the image to display • Good practice to: • Lock the controls in place on the form Clearly Visual Basic: Programming with Visual Basic 2008

  32. Mini Quiz • The name of the image file assigned to a picture box control is stored in the control’s __________ property • The value assigned to a label control’s ______ property appears in side the Control • A control’s Location Property specifies the location of the control’s _________corner on the form • How did you make the two picture boxes the same size? • To start a VB application, click Debug, and then click _________________ • Actually the best way to start a VB program is to press the F5 KEY • REVIEW QUESTIONS • A Windows form automatically contains:a. Close, Maximize, Minimize buttons b. a default caption c. a title bard. all of the above • To display the text “ABC Company” at the top of your interface, use a:a. Form b. Label C. Picture Box D. None of theses • You use the ______ window to set characteristics of an objecta. Characteristics b. Designer c. Object d. Properties • The ______ property determines the position of a form when it is rana. StartPosition b. Location c. StartLocation d. InitialPosition • When aligning 2 objects, the first control selected is called the:a. initializer b. Positioning c. reference d. none of the these
