This VB example shows how to create a Zip archive that contains "files" whose contents originate from in-memory data.

' Create a Zip compression archive containing entries
' that are compressed directly from memory.
Private Sub Command2_Click()
    
    ' Create a Chilkat Zip object
    Dim ZipFile As ChilkatZip2
    Set ZipFile = New ChilkatZip2
    
    ZipFile.UnlockComponent UnlockCode.Text
    
    ' Initialize the Zip object.  OutputZip.Text is a Text control
    ' containing the name of the Zip file that will be created.
    ZipFile.NewZip OutputZip.Text
    
    ' Add the data to the Zip object.
    Dim e As ChilkatZipEntry2
    Set e = ZipFile.AppendData("myData.txt", TextData.Text)
    
    If (e Is Nothing) Then
        MsgBox ZipFile.LastErrorText
        Exit Sub
    End If
          
    ' Compress and write to disk.
    success = ZipFile.WriteZipAndClose()
    If (success = 0) Then
        MsgBox ZipFile.LastErrorText
    Else
        MsgBox "Created Zip!"
    End If
    
    Set ZipFile = Nothing
    
    Exit Sub
    
End Sub

Private Sub Form_Load()
    OutputZip.Text = CurDir$ + "\memoryData.zip"
    
End Sub
