StrCompare Return Values
Return Value	Description

Additional Information

The StrCompare function compares the strings by checking the first character in each string, the second character in each string, and so on—until it finds an inequality or reaches the ends of the strings.

The language driver for the language that you select determines which string is greater or if the strings are the same. If you do not use a language driver, Windows uses an internal function. With a double-byte character set (DBCS) version of Windows, this function can compare two DBCS strings.
