RestoreResource Method

Syntax
QString RestoreResource(const QString& qsRevision, const QString& qsToResourcePath);
Remarks
This method restores a the specified Revision of a file resource, saving it to the given path ToResourcePath. Restoring a deleted file resource can also be done using this method as long as the revision Id is known (there's no way to obtain revision Ids for file resources which have already been deleted; this is a limitation of the Dropbox API).
Revision must be a revision Id. ToResourcePath must be a file path (and it must end with the desired name of the file resource being restored).
Error Handling
This method returns a String value; after it returns, call the GetLastErrorCode() method to obtain its result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message.
