Occurs when first volume should be inserted while extracting or testing a multi-volume archive.


public static event OnRequestFirstVolumeDelegate OnRequestFirstVolume;

public delegate void OnRequestFirstVolumeDelegate(object sender, string volumeFileName, bool cancel);



Public Shared Event OnRequestFirstVolume As OnRequestFirstVolumeDelegate

Public Delegate Sub OnRequestFirstVolumeDelegate(ByVal sender As Object, ByVal volumeFileName As String, ByVal cancel As Boolean)




Write an OnRequestFirstVolume event handler to perform asking the user for inserting a first volume of the multi-volume archive.

See also OnRequestLastVolume and OnRequestMiddleVolume events.

Also you can override default file name for this volume. Use Cancel to abort current operation.
