Dataset EnableControls/DisableControls

[luca]

Hi,
I'm working on Windows 11.

I've compiled my applications with the last version of Lazarus (4.6 32/64 bits).

I've this code

Code: Pascal  [Select][+][-]

1. ...
2.  qry.DisableControls;
3.  qry.Close;
4.  qry.Open;  
5.  if qry.eof then exit;
6. ...
7.  

With the program compiled with Lazarus version 2.2.0 all is fine: no error when I move to the grid linked to the qry dataset.
With version 4.6 I receive an Access violation when I move to the grid.

I know, there is a problem on code above: if the qry is empty the controls are not enable again because no call to EnableControls is done before exit.

But my question is: has anything changed in the new version regarding the management of data controls?

Thanks

Try removing qry.DisableControls and see how that works for you...

I have a few database apps, and I'm recompiling these all the time.  All have grids, and most having reporting/export code that iterates through datasets similar to your above, and I've seen no changes to the management of data controls in any of my apps.

Can you paste more complete code that reproduces your issue?
