Compress a String and Save as a Gzip File

See more Gzip Examples

This example demonstrates how to use the CompressStringToFile method to compress a string and write the result directly to a Gzip (.gz) file.

The input string is first converted to its byte representation using the specified character set (in this case, UTF-8). The resulting bytes are then compressed using the Gzip format, and the compressed output is written directly to the specified file.

This method is convenient when you want to generate a compressed file from in-memory text without needing intermediate objects such as BinData or StringBuilder.

loGzip = CreateObject('Chilkat.Gzip')

* The string to be compressed:
lcInputStr = "The quick brown fox jumps over the lazy dog."

* Compress the string using UTF-8 and write to a file:
lnSuccess = loGzip.CompressStringToFile(lcInputStr,"utf-8","output.gz")
IF (lnSuccess = 0) THEN
    ? loGzip.LastErrorText
    RELEASE loGzip
    CANCEL
ENDIF

? "Compression successful."
? "Gzip file written to output.gz"
