Problem is it is not work on Vista and 7. I am using SetDynamicTimeZoneInformation with SeTimeZonePrivilege on Windows Note Len may not be able to determine the actual number of storage bytes required when used with variable-length strings in user-defined data types.This is VB6 source code that I would be using to change time zone in one of our applications.

For sample code that uses LenB, see the second example in the example topic. With user-defined types, LenB returns the in-memory size, including any padding between elements. Instead of returning the number of characters in a string, LenB returns the number of bytes used to represent that string. Note Use the LenB function with byte data contained in a string, as in double-byte character set (DBCS) languages. With user-defined types, Len returns the size as it will be written to the file. One (and only one) of the two possible arguments must be specified. If varname is a Variant, Len treats it the same as a String and always returns the number of characters it contains. If varname contains Null, Null is returned. If string contains Null, Null is returned.Īny valid variable name. The Len function syntax has these parts: PartĪny valid string expression. Returns a Long containing the number of characters in a string or the number of bytes required to store a variable.
