Compressing from file to file (VB example)
In This Topic
Here are two examples for compressing from file to file. One for compression, the other for decompression.
| Visual Basic - Compression |
 Copy Code |
Dim xComp As New XceedStreamingCompression
Call xComp.License( "your license key" )
Dim vaBytesRead As Variant
Set xComp.CompressionFormat = New XceedBZip2CompressionFormat
On Error Resume Next
Call xComp.ProcessFile("c:\temp\source.txt", 0, 0, cfpCompress, True, _
"c:\temp\compressed.cmp", False, vaBytesRead)
If Err.Number = 0 Then
Call MsgBox("Compression successful!")
Else
Call MsgBox(Err.Description)
End If |
| Visual Basic - Decompression |
Copy Code |
Dim xComp As New XceedStreamingCompression
Call xComp.License( "your license key" )
Dim vaBytesRead As Variant
Set xComp.CompressionFormat = New XceedBZip2CompressionFormat
On Error Resume Next
Call xComp.ProcessFile("c:\temp\compressed.cmp", 0, 0, cfpDecompress, True, _
"c:\temp\decompressed.txt", False, vaBytesRead)
If Err.Number = 0 Then
Call MsgBox("Decompression successful!")
Else
Call MsgBox(Err.Description)
End If |
