I'm automating some excel related tasks which take a long time.
我正在自动执行一些需要很长时间的excel相关任务。
I'm creating an excel instance using:
我正在使用以下方法创建一个excel实例:
excel = win32.gencache.EnsureDispatch('Excel.Application')
wb = excel.Workbooks.Add()
however, after the script starts running, if i select an open excel workbook(not the one python is working on), The python script crashes. However, if I open a new excel workbook and type stuff into it, the python script is unaffected.
然而,在脚本开始运行后,如果我选择一个打开的excel工作簿(不是一个python正在处理),python脚本崩溃。但是,如果我打开一个新的excel工作簿并在其中键入内容,则python脚本不受影响。
Is there a particular way I can call excel to prevent this from happening? Or any other solution?
是否有一种特殊方式可以调用excel来防止这种情况发生?或任何其他解决方案?
EDIT: This seems to work.
编辑:这似乎工作。
excel = win32.DispatchEx('Excel.Application')

Why don't you do it like this?
你为什么不这样做?
from win32com import client
excel=client.Dispatch("Excel.Application")

Here's a way to create a new instance and use static cache (which is faster and gives an ability to use kwargs):
这是一种创建新实例并使用静态缓存的方法(它更快并且能够使用kwargs):
from win32com.client import gencache
import pythoncom
clsid = "Word.Application"
clsid = pythoncom.CoCreateInstanceEx(clsid, None, pythoncom.CLSCTX_SERVER,
None, (pythoncom.IID_IDispatch,))[0]
if gencache.is_readonly:
#fix for "freezed" app: py2exe.org/index.cgi/UsingEnsureDispatch
gencache.is_readonly = False
gencache.Rebuild()
olApp = gencache.EnsureDispatch(clsid)
