Returns a specified number of characters from a string.
Mid(string, start[, length])
string
The string expression from which characters are returned. If string contains Null, Null is returned.
start
The character position in string at which the part to be taken begins. If start is greater than the number of characters in string, Mid returns a zero-length string ("").
length
The number of characters to return. If omitted or if there are fewer than length characters in the text (including the character at start), all characters from the start position to the end of the string are returned.
To determine the number of characters in string, use the Len function.
The following example uses the Mid function to return six characters, beginning with the fourth character, in a string:
Dim MyVar
MyVar = Mid("VB Script is fun!", 4, 6) ' MyVar contains "Script".
Notes
The MidB function is used with byte data contained in a string. Instead of specifying the number of characters, the arguments specify numbers of bytes.
The behavior of the MidB function depends on the byte ordering of the hardware platform, and the number of bytes used to represent Unicode characters in the system software. The function will produce different results on each supported operating system. Use with caution. The described behavior pertains to the Win32 version.
