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
