Perhaps I'm doing something wrong here, but I haven't found examples for using SetStudyPersistentIntFromChart() and I'm stuck. Attached is a simple chartbook with two studies, one "driving" the other. It works for a few times, but repeatedly changing the "Master" length in the study input dialog and hitting "Apply" eventually gives me a crash in the debugger, sometimes a heap crash and sometimes a read access violation. Cheers, Dale V1580 |

We will look into this. There potentially is a problem we did not consider in this particular case.

We cannot reproduce any problem and we need specific instructions to reproduce it. Really you need to provide us an example which does not use new and delete because that is complicating it and could be where the problem is.

When using new and delete, the main thing is to make sure the pointer is not used after it has been deleted and that it is not deleted twice. And that the pointer is not used by any other instance of the study. And sc.FreeDLL must be set to 0. Sierra Chart Support - Engineering Level Your definitive source for support.
