             New QuickZip.DiskRequiredCallback(AddressOf Me.QuickDiskRequired), _

             Nothing, "d:\file.txt")



' This method will handle the DiskRequired events that are raised when creating

Private Function QuickDiskRequired(ByVal zipFile As String, ByVal diskNumber As Integer, _

                                   ByVal userData As Object) As Boolean

          Return False

     End If

End Function

XceedSfxPrefix sfx = new XceedSfxPrefix( new DiskFile( @"C:\Xceed Components\Sfx\xcdsfx32.bin" ) );



sfx.DialogStrings[ DialogStrings.Title ] = "Welcome to Xceed Zip for .NET!";

sfx.DefaultDestinationFolder = @"C:\";

sfx.ExistingFileBehavior = ExistingFileBehavior.OverwriteOlderOnly;



QuickZip.Zip( @"a:\sfx.exe", string.Empty, true, true, false, sfx, 

              new QuickZip.DiskRequiredCallback( this.QuickDiskRequired ), 

              null, @"d:\file.txt" );



// This method will handle the DiskRequired events that are raised when creating

// spanned or split zip files.

private bool QuickDiskRequired( string zipFile, int diskNumber, object userData )

{

     if( MessageBox.Show( "Disk #" + diskNumber.ToString() + " is required.", "Disk Required", 

                          MessageBoxButtons.OKCancel ) == DialogResult.OK )

          return true;
