Lesson 12 : The Formatting Functions


12.1 The Tab function

The syntax of a Tab function is Tab (n); x

The item x will be displayed at a position that is n spaces from the left border of the output form. There must be a semicolon in between Tab and the items you intend to display (VB will actually do it for you automatically).

Example 12.1

Private Sub Form_Activate
Print "I"; Tab(5); "like"; Tab(10); "to"; Tab(15); "learn"; Tab(20);"VB"
Print
Print Tab(10); "I"; Tab(15); "like"; Tab(20); "to"; Tab(25); "learn"; Tab(20); "VB"
Print Print Tab(15); "I"; Tab(20); "like"; Tab(25); "to"; Tab(30);"learn"; Tab(35); "VB"
End sub

Figure 12.1: Output of Example 12.1

12.2 The Space function

The Space function is very closely linked to the Tab function. However, there is a minor difference. While Tab (n) means the item is placed n spaces from the left border of the screen, the Space function specifies the number of spaces between two consecutive items. For example, the procedure

Example 12.2

Private Sub Form_Activate()
Print "Visual"; Space(10);"Basic"
End Sub

Means that the words Visual and Basic will be separated by 10 spaces

12.3 The Format function

The Format function is a very powerful formatting function which can display the numeric values in various forms. There are two types of Format function, one of them is the built-in or predefined format while another one can be defined by the users.

(a) The syntax of the predefined Format function is

Format (n, “style argument”)

where n is a number and the list of style arguments is given in Table 12.1


Table 12.1: List of Style Arguments

Style argument Explanation Example
General Number To display the number without having separators between thousands. Format(8972.234, "General Number")=8972.234
Fixed To display the number without having separators between thousands and rounds it up to two decimal places. Format(8972.2, "Fixed")=8972.23
Standard To display the number with separators or separators between thousands and rounds it up to two decimal places. Format(6648972.265, "Standard")= 6,648,972.27
Currency To display the number with the dollar sign in front has separators between thousands as well as rounding it up to two decimal places. Format(6648972.265, "Currency")= $6,648,972.27
Percent Converts the number to the percentage form and displays a % sign and rounds it up to two decimal places. Format(0.56324, "Percent")=56.32 %

Example 12.3

Private Sub Form_Activate()
Print Format (8972.234, "General Number")
Print Format (8972.2, "Fixed")
Print Format (6648972.265, "Standard")
Print Format (6648972.265, "Currency")
Print Format (0.56324, "Percent")
End Sub

The syntax of the user-defined Format function is

Format (n, “user’s format”)

Although it is known as user-defined format, we still need to follows certain formatting styles. Examples of user-defined formatting style are listed in Table 12.2

Table 12.2: User-Defined Formatting Functions

Format Description Output
Format(781234.576,"0") Rounds to whole number without separators between thousands  781235
 Format(781234.576,"0.0") Rounds to 1 decimal place without separators between thousands  781234.6
 Format(781234.576,"0.00") Rounds to 2 decimal place without separators between thousands  781234.58
  Format(781234.576,"#,##0.00") Rounds to 2 decimal place with separators between thousands  781,234.58
 Format(781234.576,"$#,##0.00") Displays dollar sign and Rounds to 2 decimal place with separators between thousands  $781,234.58
 Format(0.576,"0%") Converts to percentage form without decimal place  58%
 Format(0.5768,"0%") Converts to percentage form with two decimal places  57.68%

Example 12.4

Private Sub Form_Activate()
Print Format(781234.57,"0")
Print Format(781234.57, "0.0")
Print Format(781234.576,"0.00")
Print Format(781234.576,"#,##0.00")
Print Format(781234.576,"$#,##0.00")
Print Format(0.576, "0%")
Print Format(0.5768, "0.00%")
End Sub
