Methods
Function CompressFile(ByVal inFilename As String, ByVal outBz2Filename As String) As Boolean
Compresses a file to create a BZip2 compressed file (.bz2). Returns true for success, false for failure.
Function CompressFileToMem(ByVal inFilename As String) As Byte()
BZip2 compresses a file to an in-memory image of a .bz2 file. Returns a NULL object reference on failure. Returns an empty byte array on failure
Function CompressMemToFile(ByVal inData As Byte(), ByVal outFilename As String) As Boolean
BZip2 compresses and creates a .bz2 file from in-memory data. Returns true for success, false for failure.
Function CompressMemory(ByVal inData As Byte()) As Byte()
Compresses in-memory data to an in-memory image of a .bz2 file. Returns an empty byte array on failure
Function SaveLastError(ByVal filename As String) As Boolean
Saves the last error information to an XML formatted file.
Function UncompressFile(ByVal inFilename As String, ByVal outFilename As String) As Boolean
Unzips a .bz2 file. Returns true for success, false for failure.
Function UncompressFileToMem(ByVal inFilename As String) As Byte()

Function UncompressMemToFile(ByVal inData As Byte(), ByVal outFilename As String) As Boolean
Unzips from an in-memory image of a .bz2 file to a file. Returns true for success, false for failure.
Function UncompressMemory(ByVal inData As Byte()) As Byte()
Unzips from an in-memory image of a .bz2 file directly into memory. Returns a NULL object reference on failure. Returns an empty byte array on failure
Function UnlockComponent(ByVal regCode As String) As Boolean
