ReplacePart Method
Replaces the contents of the specified part in the package.
Syntax
officedoc.replacePart([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
If the part specified by the PartName property exists, the corresponding physical file will be replaced with the contents of the PartData property. The package file will be modified in place right away.
If the part doesn't exists, it's stored in interleaved format, or PartData is null or empty, an error will be raised.
