Question

This was continuation to my previous question.

I dont want PARAMS CHANGE_LOG data in my XML file while saving the data in ClientDataSet using ClientDataSet1.SaveToFile() method.

My code looks like this:

ClientDataSet1.Insert;
ClientDataSet1.FieldByName('Name').AsString:= 'AAA';
ClientDataSet1.Append;
ClientDataSet1.SaveToFile('c:\Test.xml',dfxml);

How can i achieve this.

Set the LogChanges property of your CLientDAtaSet to False, and it will not bulid the ChangeLog for you...

Thanks Bob. Can you suggest me which is more effective MergeChangeLog or LogChanges=False – Bharat Oct 22 '10 at 12:48
@Bharat - If you won't make use of the change log, setting 'LogChanges' to false is more effective. When LogChanges is true, data editing becomes slower over time (until changes are merged). – Sertac Akyuz Oct 22 '10 at 19:06
Setting LogChanges to False is more efficient, since it never needs to save the deltas, and will just apply the changes with every post or insert/delete. – Bob Swart Nov 09 '10 at 21:49

Using ClientDataSet1.MergeChangeLog before saving the XML file solves the problem.

Code looks like this:

ClientDataSet1.MergeChangeLog;
ClientDataSet1.SaveToFile('c:\Test.xml',dfXML);
