Re: Random access violations

I was deleting some empty samples today and sporadically received access violation errors. What are these seemingly random errors and what causes them?

Exception occurred in application Recorder 6 at 09/01/2007 13:27:10.
Version : 6.9.3.102

Exception path:
EAccessViolation : Access violation at address 0053A21F in module 'Recorder.ex_'. Read of address 0000008A

Re: Random access violations

They are generally caused by code errors, but could be errors in Recorder code, or a 3rd party control or library, or even the data access components that are at fault. As a rule of thumb, if you can provide a method for reliably reproducing them then we are likely to be able to fix them or find a code workaround.

Re: Random access violations

Thanks John, I'll bear that in mind. As I say, this one is pretty random and so I couldn't provide a reliable method of reproduction. For what it's worth, I was deleting a bunch of empty samples in rapid succession using the keyboard (hitting delete, then enter). Every so often, the error would be thrown.
