Using character codes
Strings can contain a number of elements. In previous examples, I show you
strings that contain control character constants such as 
vbCrLf
. This con-
stant actually contains two control characters: a carriage return and a line
feed. The carriage return sends the cursor back to the beginning of the line;
the line feed places the cursor on the next line. The result of using both con-
trol characters together is the same as pressing Enter on the keyboard.
Strings can also use a special function, 
Chr
, to create special characters. You
can combine this function with the Character Map utility (normally available
on the Start
➪
Programs
➪
Accessories menu) to produce any character that
you need for your program. Figure 4-2 shows a typical Character Map display.
(Vista doesn’t include Character Map in the list of applications. To access
Character Map in Vista, choose Start
➪
Run. Type 
Charmap
in the Open field
of the Run dialog box and click OK.)
When you hover the mouse over a character, the balloon help displays the
Unicode character number in hexadecimal or base 16 (see the upcoming
“Defining hex and octal values” section for details). Selecting the character
displays the Unicode number in the lower-left corner of the Character Map
dialog box and displays the character in a larger size. Listing 4-3 shows the
Chr
function in use.
