CloneCursor

Posted: 2008/03/14 03:58

Hi!

I'm trying to use the CloneCursor.
Wenn I edit this cloned cursor (edit...post) the process runs without any message, but the correction will not be saved.

cursor2.CloneCursor(cursor1, false);
cursor2.edit;
cursor2.fieldbyname('f1').AsString := 'new value';
cursor2.post;

Database: MSAccess

Please help me!

CloneCursor will not work for TADQuery. It works only for TADClientDataSet.

It does not copy Adapter property value.

Thanks!!!!!!!!

So it is ok:

cursor2.CloneCursor(cursor1, false);
cursor2.Close;
cursor2.Adapter := cursor1.Adapter;
cursor2.open;

Strange! In AnyDAC demo (fCloneCursor.pas) is without copy of Adapter, and unfortunatly there is no documentation.

Thanks again!

I have one more (perhaps studip) question:
After editing to cloned cursor how can I the changes synchronize with the "parent" cursor?
- it does not work automatic
- refreshrecord hilfs, but only for the current record
- refresh of parent cursor causes a GPF

- reconcile ...? -no result
- ...?

Actually, both cursors refers to the same physical record storage.
So, just try to call Resync([]).
