Changing Datasource Active Property from True to False crashes IDE

I have a program written using the DBF control and the Datasource
control. If I change either one from True to False in the Active
property, it crashes the entire IDE.

Help!

Did you point the TDbf control correctly to an existing .dbf file? The
only crashes I ever had with TDbf were when it couldn't open a file...

Yes... it's connected and data controls working fine. Program runs
fine. But it won't allow me to change the filepath because the
datasource control is active. When I try to change it to false, the
IDE shuts down.

Hi Walt,

when I set DBF1.Active:= FALSE then App crashes - which is does not
lead to a shutdown on my PC because I activated all DEBUG switches in
the Project Properties Settings. Error Message is:

"Operation cannot be performed on an inactive dataset."


So, please, activate Debug Switches while developing (IO, Overflow,
Stack etc. ..)
Only disable them on compiling a release version of Your Application.
Or when You code timecritcal things as device drivers or native Audio
IO or so.

Cheers,
Peter
