Spc Function

Syntax

Spc(n)


n

Use: Required

Data Type: Integer

The number of spaces required.

Return Value

A String containing n spaces.

Description

Inserts spaces between expressions in a Print # statement, Debug.Print method, or Printer.Print method.

Rules at a Glance

  • Although Spc has more built-in "intelligence" than the Space function, it can be used only with the Print # statement and the Debug.Print method. For example, it isn't possible to use the Spc function to pad a fixed-length string as the Space function does. When dealing with the Printer object, far more flexibility is available by setting properties, such as CurrentX, for accurately placing text strings.

  • If the width of the device being printed to is greater than n, the print position is set to be immediately after the number of spaces printed by the Spc function.

  • If the width of the device being printed to is less than n, the print position is set to the current position plus the result of the formula n Mod devicewidth.

  • If n is greater than the difference between the current print position and the width of the device, Spc inserts a line break and then inserts spaces in accordance with the following formula:

    n - (devicewidth - currentposition)

  • When using a proportional font, the Spc function uses the average width of all characters for the particular font to determine the width of the space character to print.

  • When the number of fixed-width columns is important, you should use either the Space or the Tab function, since there isn't necessarily a relationship between the spaces provided by the Spc function and fixed-width columns.

Programming Tips and Gotchas

  • When placing output on the Printer object, use the TextWidth method to determine the actual width taken up by a given string in a given font and font size.

  • While on the surface it appears that Spc and Space are interchangeable functions that both simply return a given number of spaces, their internal workings are somewhat different. The Spc function can be used only in conjunction with a Print or Print # function. For example, you generate a design-time error if you try to write the following code:

    Dim sStr As String * 20
    'no can do
    sStr = Spc(20)
