I'm very new to Python, well IronPython to precise, and have been having problems when using Excel.
The problem I'm having is the closing of my Excel object. I'm able to successfully quit the Excel Application that I create, but when I open a Workbook in the Application I can't successfully Quit Excel (by this I mean I can quit it, but the Excel process isn't getting killed and I have to manually go this through Task Manager). I've given a sample of code below to hopefully make things clearer. I've then given all of the information I think might be useful (sorry if I've gone over the top!). import System import clr from System.Data import * from System.Web import * from System.Web.UI import * from clr import * clr.AddReference("Microsoft.Office.Interop.Word") clr.AddReference("Microsoft.Office.Interop.Excel") clr.AddReference("Microsoft.Office.Interop.PowerPoint") clr.AddReference("Office") from Microsoft.Office.Interop.Word import ApplicationClass as WordApplication from Microsoft.Office.Interop.Excel import ApplicationClass as ExcelApplication from Microsoft.Office.Interop.PowerPoint import ApplicationClass as PowerPointApplication from Microsoft.Office.Interop.Word import WdReplace from Microsoft.Office.Interop.Excel import XlCellType from Microsoft.Office.Interop.Excel import XlSearchDirection from System.Type import Missing from System import GC missing = Missing FileLocation = "C:\\test.xls" ExcelApp = ExcelApplication() workbook= None workbook = ExcelApp.Workbooks.Open(FileLocation, missing, missing, missing, missing, missing, missing, missing, missing, missing, missing, missing, missing, missing, missing) workbook.Save() workbook.Close(SaveChanges=0) ExcelApp.Quit() workbook = None ExcelApp = None GC.Collect() GC.WaitForPendingFinalizers() I've simpilised the code by taking all of my Workbook processing from it and the problem is still occurring. As I said above if I don't create the workbook, then ExcelApp closes as expected (there are no stray processes). I've read many articles and postings over the last few days regarding this, but have had no luck with anything I've seen, examples of this are now given. I've tried adding the below code, but with no luck. ExcelApp.ActiveWorkbook.Save() ExcelApp.ActiveWorkbook.Close(SaveChanges=0) ExcelApp.Workbooks.Close() I've also tried the below (again with no luck). System.Runtime.InteropServices.Marshal.ReleaseComObject(workbook) System.Runtime.InteropServices.Marshal.ReleaseComObject(excelApp) And, I've also tried the following (again with no luck!). del(workbook) del(excelApp) It may seem strange using the Garbage Collector (well I wouldn't have thought about using it here), but it was something that I read about using for code written in C#. I've tried the code in C# (what I normally write in) and all works fine, the only real difference is that I'm setting the objects to NULL in C# and None here in IronPython - Does this make a difference, is there something else I should be setting it to? The Workbook object HAS to be set to NULL in C#, it's then picked up by the Garbage Collector and the task disappears from the Task Manager. I did think of killing the actual EXCEL.EXE process at the end of my code, but there might be several versions of the containing application running on the same box, so I can't kill all of the Excel processes. As I said above, I'm sorry if I've gone over the top in my description. Any ideas or pointers would be greatly appreciated as I'm now going round in circles. Thanks in advance.
