I am using the code below, but Visual Studio always gives me this error:

\r\n

"MyExtractProgress is not declared"

\r\n

What should I declare it as?

\r\n

\r\n

  Dim ZipToUnpack As String = "C1P3SML.zip"  
   Dim TargetDir As String = "C1P3SML"  
   Console.WriteLine("Extracting file {0} to {1}", ZipToUnpack, TargetDir)   
   Using zip1 As ZipFile = ZipFile.Read(ZipToUnpack)   
       AddHandler zip1.ExtractProgress, AddressOf MyExtractProgress   
       Dim e As ZipEntry   
       ' here, we extract every entry, but we could extract    
       ' based on entry name, size, date, etc.   
       For Each e In zip1   
           e.Extract(TargetDir, ExtractExistingFileAction.OverwriteSilently)   
       Next  
   End Using

Thanks!
\r\n

It is an event handler; it's documented in the .chm file. If you look for the ZipFile.ExtractProgress property, it gives you an example that includes this code:

\r\n
Public Shared Sub MyExtractProgress(ByVal sender As Object, ByVal e As ExtractProgressEventArgs)\r\n    If (e.EventType Is ZipProgressEventType.Extracting_EntryBytesWritten) Then\r\n        If ExtractTest.justHadByteUpdate Then\r\n            Console.SetCursorPosition(0, Console.CursorTop)\r\n        End If\r\n        Console.Write("   {0}/{1} ({2:N0}%)", e.BytesWritten, e.TotalBytesToWrite, (CDbl(e.BytesWritten) / (0.01 * e.TotalBytesToWrite)))\r\n        ExtractTest.justHadByteUpdate = True\r\n    ElseIf (e.EventType Is ZipProgressEventType.Extracting_BeforeExtractEntry) Then\r\n        If ExtractTest.justHadByteUpdate Then\r\n            Console.WriteLine\r\n        End If\r\n        Console.WriteLine("Extracting: {0}", e.NameOfLatestEntry)\r\n        ExtractTest.justHadByteUpdate = False\r\n    End If\r\nEnd Sub\r\n
\r\n

Such an event handler would make sense only if you are using the code within a Cosnole app. If it is a WinForms app, you will want to update a status textbox, or a progressbar, or something else with each call of the event handler.
