Use VB to distinguish between an xlsx event from C# Interop or Excel program

由 随声附和 提交于 2019-12-08 04:00:43
问题 I have an event that I want triggered when a user closes a .xlsx file. I also have a C# program that regularly checks the content within that same file. The problem I have is that when my C# program (which uses Interop) closes the .xlsx file, it triggers my VB code. Is there a way to isolate access to the excel file so that I know it was edited within the Excel program? I only want my VB code triggered when a user edits the file within Excel. Thanks 回答1: I decided to simply have my C# program

问题 How can I convert an existing xlsx Excel file into xls while retaining my Excel file formatting? I use Anaconda Python 3, so I'm not sure I can use xlutils ... I was not able to install it via conda install xlutils because of lots of incompatibilities. So now I use this code without the xlutils.copy() : import xlrd, xlwt wb = xlrd.open_workbook(my_xlsx_excel_file) # wb = xlutils.copy(wb) wb.save(my_xlsx_excel_file[:-1]) And I get this error: AttributeError: 'Book' object has no attribute
