Download: Chilkat .NET Assemblies

C# example program showing how to create a .zip with progress monitoring event callbacks.

    // Called by Zip.WriteZip, WriteZipAndClose, or WriteExe
    public void OnWriteZipPercentDone(object source, Chilkat.WriteZipPercentDoneEventArgs args)
    {

	// To abort the Zip while in progress, set the Abort flag = true
	//args.Abort = true;
    }

    // Callback from with Zip.AppendFiles or Zip.AppendFilesEx
    public void OnDirToBeAdded(object source, Chilkat.DirToBeAddedEventArgs args)
    {
	// The directory may be excluded by settings args.Exclude = true
	//args.Exclude = true;
	
	listBox1.Items.Add(args.DirName);
    }
    
    // Callback from with Zip.AppendFiles or Zip.AppendFilesEx
    public void OnToBeAdded(object source, Chilkat.ToBeAddedEventArgs args)
    {
	listBox1.Items.Add(args.FileName);
	
	// The file may be excluded by setting args.Exclude = true
	//args.Exclude = true;
    }

    // Called during WriteZip, WriteZipAndClose, or WriteExe
    // This is called for each file/directory just before it is to be compressed
    // and written into the .zip.

	zip.NewZip("test.zip");

	zip.AppendFromDir = "c:/temp/";
