Here are two examples for compressing from file to file. One for compression, the other for decompression.
| VB.NET - Compression |
 Copy Code |
Dim compressor As New XceedStreamingCompressionLib.XceedStreamingCompressionClass()
compressor.License( "your license key" )
Dim bytesRead As object = Nothing
compressor.CompressionFormat =
New XceedStreamingCompressionLib.XceedBZip2CompressionFormatClass()
Try
compressor.ProcessFile( "c:\test\file.txt", 0, 0,
XceedStreamingCompressionLib.EXCFileProcessing.cfpCompress,
true, "c:\test\file.cmp", false, bytesRead )
Catch except As System.Runtime.InteropServices.COMException
MessageBox.Show( except.ToString() )
End Try |
| VB.NET - Decompression |
Copy Code |
Dim compressor As New XceedStreamingCompressionLib.XceedStreamingCompressionClass()
compressor.License( "your license key" )
Dim bytesRead as Object = Nothing
compressor.CompressionFormat = New XceedStreamingCompressionLib.XceedBZip2CompressionFormatClass()
Try
compressor.ProcessFile( "c:\test\file.cmp", 0, 0,
XceedStreamingCompressionLib.EXCFileProcessing.cfpDecompress,
true, "c:\test\file2.txt", false, bytesRead )
Catch except As System.Runtime.InteropServices.COMException
MessageBox.Show( except.ToString() )
End Try |
