I have an application that uses a container. I chose as the active X object an Excel Shpeadsheet, but I notice that the container reference is to an Excel Workbook, OK fine. I use the properties and methods to select sheets in the workbook and to read and write data, no problems. The problem comes when I go to close down. I have tried closing all references, but when I finish Excel is still running long after I close labview. I have plenty of experience with straight out active x and have performed these same actions on Excel without the container. What is different about the container. It seems to automatically start Excel, but gives no way of closing it. I even tried calling the parent of the workbook(W
orkbooks), the parent of workbooks(Excel application) and closing down and deleting their references in reverse order of their creation, still Excel runs. Anyone out there solve this problem?
