The actions taken by the Colors dialog box are controlled by the following event procedures, associated with the OK and Cancel buttons. (Recall that the identifiers vbRed, vbBlue, vbBlack and vbMenuBar are predefined Visual Basic constants that represent the colors red, blue, black and gray, respectively.)

If Option4.Value = True Then Form2.BackColor = vbRed Form2.Label1.BackColor = vbRed ElseIf Option5.Value = True Then Form2.BackColor = vbBlue Form2.Label1.BackColor = vbBlue ElseIf Option6.Value = True Then Form2.BackColor = vbMenuBar 'Gray Form2.Label1.BackColor = vbMenuBar End If Dialog1.Hide End Sub Private Sub CancelButton_Click() Dialog1.Hide End Sub
The Fonts dialog box works the same way as the Colors dialog box. Here are the event procedures associated with the OK and Cancel buttons.
Private Sub OKButton_Click() If Option1.Value = True Then Form2.Label1.FontSize = 8 Form2.Text1.FontSize = 8 ElseIf Option2.Value = True Then Form2.Label1.FontSize = 10 Form2.Text1.FontSize = 10 ElseIf Option3.Value = True Then Form2.Label1.FontSize = 12 Form2.Text1.FontSize = 12 End If Dialog2.Hide End Sub Private Sub CancelButton_Click() Dialog2.Hide End Sub
Finally, the primary form includes the following two additional event procedures.
Private Sub Form1_Load() Load Form2 Load Dialog1 Load Dialog2 End Sub Private Sub Command1_Click() End End Sub
The first event procedure causes the three dialog boxes to be loaded into the computer s memory (but not displayed) when the application begins. The second event procedure simply ends the computation. Execution of the program produces results similar to those shown at the beginning of the example [see Figs. 5.22(a) and (b), 5.23(a) and (b), and 5.24(a) and (b)].
CHAP. 5]
MENUS AND DIALOG BOXES
5.7 MORE ABOUT THE MsgBox FUNCTION We first discussed the MsgBox function in Sec. 4.13, where we used it to create error messages. The form generated by this function is actually a type of dialog box which displays a given output string and one or more command buttons (e.g., OK), and returns a positive integer whose value depends on the action taken by the user. (In this situation, the user action consists of clicking on one of the available command buttons.) The choice of command buttons is determined by a nonnegative integer that is included in the function reference. In general terms, the function reference may be written as
integer variable = MsgBox(string, integer, title)
The value of the integer argument (default 0) defines the command buttons that appear within the dialog box. Also, title represents a string that will appear in the message box s title bar. It s default value (if not included as an explicit argument) will be the project name. The function s return value (a positive integer whose value depends on the particular command button selected by the user) is assigned to the integer variable shown on the left of the equal sign. Note that the integer argument and the return value are two different entities. Some of the more commonly used integer arguments and their resulting MsgBox command buttons are summarized below. Integer Argument 0 1 2 3 4 5 Resulting Command Buttons
OK OK, Cancel Abort, Retry, Ignore Yes, No, Cancel Yes, No Retry, Cancel
The value returned by the MsgBox function will depend upon the particular command button selected by the user during program execution. The possible values are summarized below. Command Button
OK Cancel Abort Retry Ignore Yes No
Return Value 1 2 3 4 5 6 7
EXAMPLE 5.8
Consider the Visual Basic code segment shown below. Initially, the variables CustomerName and AcctNo are assigned null values, and a value of 7 is assigned to the integer variable Verify. Assigning this value to Verify causes the Do-Loop structure to continue to execute repeatedly, until Verify is assigned a different value within the loop. Meaningful values are assigned to the input variables during each pass through the loop. (Let us disregard the details of where these values originate.) The message box shown in Fig. 5.31 is then displayed. Notice the three command buttons (Yes, No and Cancel), as determined by the second argument (3) in the MsgBox function access. Also, notice the message box title (Sample Message Box) in the title bar, as specified by the third argument in the MsgBox function access.
