Compress Text from StringBuilder to Gzip (BinData Output)

See more Gzip Examples

This example demonstrates how to use the CompressSb method to compress text stored in a StringBuilder into Gzip format.

The text is first converted to its byte representation using the specified character set (in this case, UTF-8). These bytes are then compressed, and the resulting Gzip data is written to a BinData object in memory.

This approach is useful when working with dynamically generated text that you want to compress without first writing it to a file. The example also shows how the compressed data can optionally be saved to a .gz file.

Dim gzip As New Chilkat.Gzip
Dim sb As New Chilkat.StringBuilder
Dim bd As New Chilkat.BinData

// Add some text to the StringBuilder:
success = sb.Append("The quick brown fox jumps over the lazy dog.")

// Compress the text using UTF-8 encoding:
success = gzip.CompressSb(sb,"utf-8",bd)
If (success = False) Then
    System.DebugLog(gzip.LastErrorText)

End If

// The BinData now contains the Gzip-compressed bytes.
System.DebugLog("Compression successful.")
System.DebugLog("Compressed size (bytes): " + Str(bd.NumBytes))

// (Optional) Save to a .gz file:
success = bd.WriteFile("text.gz")
