VB6 Tutorial 35: Formatting Functions
This lesson will take you through the formatting functions in Visual Basic 6 which you can use to format numeric or string expressions.
You have probably seen in many applications that you enter a number and that number is displayed in a different format for a better readability. Formatting functions are useful when you want to represent an expression in many different ways. For instance, you may want to convert an expression to currency format, phone number format, credit card number format or percentage format. Sometimes its necessary to represent the date-time values in a couple of ways. Visual Basic 6.0 has included many powerful functions in order to achieve this.
FormatNumber
The FormatNumber function converts an expression to the numeric format.
Example
Print FormatNumber(2234.789, 2)
Output: 2234.79
FormatCurrency
The FormatCurrency function converts an expression to the currency format.
Example
Print FormatCurrency(2234.789,2)
Output: $2234.79
FormatPercent
The FormatPercent function converts the expression to the percentage format.
Example
Print FormatPercent(.225, 2)
Output: 22.50 %
Displaying current Date/Time
Before showing you formatting date-time values, lets see how to display date and time. Remember that Time and Date are properties, not functions in the following example.
Private Sub cmdShowDateTime_Click()
'Displays current time
Print Time '12:53:12 PM
'Displays current date
Print Date '04-09-2012
'Displays current date,time
Print Now '04-09-2012 12:53:12 PM
End Sub
FormatDateTime
The FormatDateTime function displays a date/time value in different formats.
Example
Print FormatDateTime("2 - 3 -2012", vbLongDate)
Print FormatDateTime(Now, vbLongDate)
Print FormatDateTime(Time, vbShortTime) 'Displays current time
Print FormatDateTime(Time, vbLongTime)
Output:
02 March 2012
04 September 2012
12:01
12:03:28 PM
Format
The Format function is the most useful among all the formatting functions in the sense that it can be used to perform many formatting tasks. You can use this function to format date-time values, phone number or credit card number, currency and many others.
Example
Print Format(8765, "@@@@@@@")
Output: 8765
Three spaces before 8765.
You can use the Format function to format different types of expressions. The below example shows this.
Example
Print Format("abc", "@@@@@@@@@") ' abc
Converts into currency form
Print Format(123, "Currency") ' $123
Converts into uppercase
Print Format("xyz", ">&&&") ' XYZ
Converts into lowercase
Print Format("HELLO", "<&&&&&") ' hello
Converts into phone number or credit card no. form
Print Format(9845678972#, "&&&&-&&-&&&&") ' 9845-67-8972
Short Time
Print Format(Now, "hh:mm") ' 12:38
Print Format(Now, "hh:mm:ss") ' 12:38:00
Print Format(Now, "hh:mm AMPM") ' 12:38 PM
Print Format(Date, "dddd mmm dd, yyyy") ' Tuesday September 04, 2012
Print Format(Date, "dd mmmm") ' 04 September
