Chapter 2 P. 1 Introducing more controls (on the Toolbox) (Fig. 2.1) - Text box - Frame - Option button - Check box - Image Example P. 44 Figure 2.2 Message formatter Text boxes The white box next to “Your Name” The white box next to the words “Message” Frame The box enclosing the Color buttons The box enclosing the Style buttons Option buttonThe buttons labeled Red, Green, Blue, Black. Check boxes The boxes labeled Bold, Italic, and Underline. Image The picture of the CD at the lower left. More Controls

Chapter 2 P. 2 Labels The label containing “Your Name” The box containing “Message” The two blank boxes at the bottom of the screen The label containing “Click Me” Command buttons - Display, Clear, Print, Exit Create the form in the book Create the labels Create the label containing “Your Name” - you need not change the Name - in Properties change Caption to “Your Name” Create the label containing “Message” - you need not change the Name - in Properties change Caption to “Message” Create one blank label at the bottom center of the form - in Properties change Name to lblMessage - in Properties delete Caption

Chapter 2 P. 3 - create the label containing “Click Me” - you need not change the Name - in Properties change Caption to “Click Me” Note: You need to change the name of a label if you refer to the label in the code; i.e., if you place some message in the label. Create the text boxes - create text box by “Name” (user types a name at run time) - create a Text box next to “Your Name” - in Properties change Name to txtName - in Properties delete the Text - create text box by “Message” (user types a message at run time) - create a Text box next to “Message” - in Properties change Name to txtMessage - in Properties delete the Text

Chapter 2 P. 4 - center the message in this box (this can be done only at design time) - in Properties set Multiline to True - in Properties set Alignment to 2-Center Note: The Name of a text box begins with txt. Note: A label box has a Name and Caption. A text box has a Name and Text. Example You can write lblMessage.Caption = txtMessage.Text in the code. This places the message in the second text box into the label box. (This will go into the code for the Display button.) Create the frames (for the Color and Style) A frame is a control which contains several other controls.

Chapter 2 P. 5 - create the Color frame - in the Toolbox use the Frame tool to draw a frame - in Properties change Name to fraColor - in Properties change Caption to Color - create the Style frame - in the Toolbox use the Frame tool to draw a frame - in Properties change Name to fraStyle - in Properties change Caption to Style Create the check boxes for Style - create the check box for Bold - in the Toolbox use the Check box tool to draw a check box within the Style frame - in Properties change Name to chkBold - in Properties change Caption to Bold - create the check boxes for Italic and Underline

Chapter 2 P. 6 Note: you must draw the check boxes and option buttons inside the appropriate frame; you can not create them and then drag them into the frame. Place the Image onto the form The VB folder contains several Images, which you can copy into your form. Simply use Copy and Paste. - in the Toolbox use the Image tool to draw a control for the Image - in Properties change Name to imgCDROM - copy in the picture - in Properties select Picture (Fig ) - find the picture you want (the CD-ROM) - select Program Files, Dev Studio, VB, Graphics, Icons, Computer, CDROM

Chapter 2 P. 7 - double-click on the image - copy in the other picture - create a new Image frame - copy the other image into the frame - when both pictures are on the frame, drag one image frame on top of the other Note: copying one picture on top of another will hide one of the pictures. In the code we will see how to show each of the pictures alternately. - set other properties - enlarge the image - resize the Image control - in Properties set Stretch to True - hide the picture - set Visible to False (in the code)

Chapter 2 P. 8 - giving a 3-dimensional appearance to controls - in Properties select Borderstyle to 1 - 3D - in Properties select Appearance and 1-3D Working with multiple controls Select multiple controls “Draw” a box around the controls with the cursor or hold the Shift key and click on the controls Deselecting a group of controls Click outside the selected group Moving controls as a group Click and drag Setting properties for multiple controls Align controls

Chapter 2 P. 9 Setting properties for user convenience Defining keyboard access keys (for command buttons, option buttons, and check boxes) - in Properties put the & symbol before a letter in the Caption for a command button - the letter will appear underlined on the form - the user can hit Alt and that letter to activate the command Example In the message formatter there is an underline under R in the word Red. If the user hits Alt R, then the message appears red. Setting the default and cancel properties Default- in Properties set Default to True - user activates this button with Return Cancel- in Properties set Cancel to True - user activates this button with Esc

Chapter 2 P. 10 Set the tab order for controls - in Properties select Tabindex - type in a number indicating the order in which you want the control to be chosen when the program runs - Example In Properties set Tabindex to 4. When you run the program, if you hit the Tab key, this control will be the fourth one to be activated. Coding for the controls Clearing text boxes and labels (in code) - text box - set the Text to “ “ - Example txtName.text= “ “ -label - set the Caption to “ “ - Example lblMessage.Caption = “ “

Chapter 2 P. 11 Resetting the focus Definition The focus is the control which holds the cursor when the program starts. Example To set the focus in the Name text box, the command is txtName.SetFocus. (In the Text formatter, this command occurs in the code for the Clear control.) Setting the value properties of option buttons and check boxes (in code) Example Check the Red option button optRed.Value=True Example Check the Bold check box chkBold.Value = 1 OR chkBold.Value = Checked Example Uncheck the Bold check box chkBold.Value = 0 OR chkBold.Value = Unchecked

Chapter 2 P. 12 Changing the font properties of controls - before running the program - in Properties select Font - in the dialogue box check the desired properties - in code - assign the appropriate font property and value -Example txtName.Font.Bold = True lblMessage.Font.Size = 12 lblTitle.Font.Italic = True Changing the color of text (in code) - set the ForeColor to one of the color constants vbBlack, vbRed, etc. (see P. 55)

Chapter 2 P. 13 Changing multiple properties of a control Example Book P. 56 The codetxtTitle.Visible = True txtTitle.ForeColor = vbWhite txtTitle.Font.Bold = True txtTitle.Font.Italic = True txtTitle.SetFocus can be rewritten asWith txtTitle.Visible = True.ForeColor = vbWhite End With Concatenating text Use the &symbol Example lblMessage.Caption = “Hello” & “ “ & txtMessage.text

Chapter 2 P. 14 Continuing program lines Use &_ Example lblMessage.Caption = “If you return the winning number,” &_ txtName.text &”, you will be rich!” Using the value of controls Example lblMessage.Caption = txtName.text
