Description & Usage

lstrlen determines the length of a string. The length of a string is considered to be the number of characters it contains, not counting any possible terminating null character. This function can also determine the length of a string to which a pointer refers.

Return Value

The function returns the length of the string, measured in number of characters.

Visual Basic-Specific Issues

This function is very useful, in conjunction with lstrcpy, for "converting" a pointer to a string into an actual string.

Parameters

lpString

Either the string to determine the length of or a pointer to the string to determine the length of.

Example

' This code is licensed according to the terms and conditions listed here. ' Display the length of the string "Hello, world!" Dim slength As Long  ' receives the length of the string slength = lstrlen("Hello, world!")  ' find the length of the string Debug.Print "The string 'Hello, world!' contains"; slength; "characters."
