 Begins an asynchronous buffer write. Currently the CryptoStream class does not
 support asynchronous buffer writing.
 Public Function BeginWrite(
	  ByRef Buffer ( ) As Byte,
	  ByVal Offset As Long,
	  ByVal Count As Long,
	  Optional ByVal Callback As AsyncCallback,
	  Optional ByRef State As Variant ) As IAsyncResult
Parameters
- Buffer
 - 
[ByRef]
 Byte.
  The source array to copy the bytes from into the stream.
 
 
- Offset
 - 
[ByVal]
 Long.
  The starting index in the source Buffer to begin copying from.
 
 
- Count
 - 
[ByVal]
 Long.
  The maximum number of bytes to be copied into the stream.
 
 
- Callback
 - 
[ByVal]
 Optional.
 AsyncCallback.
  A user supplied object to be notified of the finish of the writing.
 
 
- State
 - 
[ByRef]
 Optional.
 Variant.
  User data that can be carried within the IAsyncResult object return.
 
 
Return Values
IAsyncResult -  An IAsyncResult object used to identify the corrisponding EndBread and report
