Add Binary Data to a ZIP Using AddBd

See more Zip Examples

This example demonstrates how to use the AddBd method to add binary data from a BinData object as a file entry within a ZIP archive.

The data is created entirely in memory, added to the ZIP as data/binary.dat, and then written to disk.

Ruby

require 'chilkat'

success = false

# Create a new ZIP archive.
zip = Chilkat::CkZip.new()

success = zip.NewZip("inMemoryData.zip")
if (success == false)
    print zip.lastErrorText() + "\n";
    exit
end

# Create a BinData object containing binary content.
bd = Chilkat::CkBinData.new()

# Append some bytes as hexadecimal.
# The decoded bytes will become the contents of the ZIP entry.
success = bd.AppendEncoded("000102030405060708090A0B0C0D0E0F","hex")
if (success == false)
    print bd.lastErrorText() + "\n";
    exit
end

# Add the BinData contents as a file entry within the ZIP.
# The file will be stored as "data/binary.dat" inside the ZIP archive.
success = zip.AddBd("data/binary.dat",bd)
if (success == false)
    print zip.lastErrorText() + "\n";
    exit
end

# Write the ZIP archive to disk and close it.
success = zip.WriteZipAndClose()
if (success == false)
    print zip.lastErrorText() + "\n";
    exit
end

print "ZIP archive created successfully." + "\n";
