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.

VB.NET

Dim success As Boolean = False

' Create a new ZIP archive.
Dim zip As New Chilkat.Zip

success = zip.NewZip("inMemoryData.zip")
If (success = False) Then
    Debug.WriteLine(zip.LastErrorText)
    Exit Sub
End If


' Create a BinData object containing binary content.
Dim bd As New Chilkat.BinData

' Append some bytes as hexadecimal.
' The decoded bytes will become the contents of the ZIP entry.
success = bd.AppendEncoded("000102030405060708090A0B0C0D0E0F","hex")
If (success = False) Then
    Debug.WriteLine(bd.LastErrorText)
    Exit Sub
End If


' 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) Then
    Debug.WriteLine(zip.LastErrorText)
    Exit Sub
End If


' Write the ZIP archive to disk and close it.
success = zip.WriteZipAndClose()
If (success = False) Then
    Debug.WriteLine(zip.LastErrorText)
    Exit Sub
End If


Debug.WriteLine("ZIP archive created successfully.")
