As I understand, he's looking for an "Automated" way to create VCL-components on the fly, in this case TClientDataSets, not the table-data that is IN a TClientDataSet.
You might want to investigate the TReader and TWriter objects, which Delphi internally uses to stream-in and -out DFM-files.

Here is what the help file has to say on the subject: Call *SaveToFile* to write a client dataset's data to an external file for later use by this or other client datasets. FileName is the name of the external file to use. If the file already exists, its current contents are overwritten. If an empty string is passed for the FileName <DBClient.TCustomClientDataSet.FileName.html> parameter (or, in Delphi, if this parameter is omitted), the data is saved to the file specified by the FileName <DBClient.TCustomClientDataSet.FileName.html>property. Format indicates what format to use when saving the data, binary (dfBinary) or XML (dfXML), or UTF8-based XML (dfXMLUTF8).
