LoadFromFile Method

Copies contents of a file-based vault into the in-memory vault.

Syntax

cbmemdrive.loadFromFile(fileName, [callback])

Callback

The 'callback' parameter specifies a function which will be called when the operation completes (or an error is encountered). If the 'callback' parameter is not specified, then the method will block and will not return until the operation completes (or an error is encountered).

The callback for this method is defined as:

function(err){ }

'err' is the error that occurred. If there was no error, then 'err' is 'null'.

'err' has 2 properties which hold detailed information:

err.code
err.message

Remarks

This method loads the contents of the vault, specified by FileName, into the class.

If the in-memory vault is not opened, LoadFromFileopens an in-memory vault. If the in-memory vault is already opened, it is closed by this method.

If the vault is encrypted, then before calling LoadFromFile, the application should set proper values to VaultEncryption and VaultPassword properties.

Note: This method can only be called when Active is true, and cannot be called within events.
