Hi. This issue is for an ActiveX Automation interface for scripting MaximDL. I'm making 3rd party autofocus software while shooting by using MaximDL. I need to get filter-index which is current shooting by calling this function. maximDL.Filter This procedure works well at MaximDL 6. It means the MaximDL 6 gives filter-index for the filter which current whooting. In case of maximDL 5 (v5.24), single shooting mode works well but the MaximDL 5 never give the filter-index in "Autosave" batch shooting mode. Why its not working? I think this is a kind of bug. Does anybody know for this??
