I'm trying to run a macro via python but I'm not sure how to get it working...

I've got the following code so far, but it's not working.

import win32com.client
xl=win32com.client.Dispatch("Excel.Application")
xl.Workbooks.Open(Filename="C:\test.xlsm",ReadOnly=1)
xl.Application.Run("macrohere")
xl.Workbooks(1).Close(SaveChanges=0)
xl.Application.Quit()
xl=0

I get the following traceback:

Traceback (most recent call last):
  File "C:\test.py", line 4, in <module>
    xl.Application.Run("macrohere")
  File "<COMObject <unknown>>", line 14, in Run
  File "C:\Python27\lib\site-packages\win32com\client\dynamic.py", line 282, in _ApplyTypes_
    result = self._oleobj_.InvokeTypes(*(dispid, LCID, wFlags, retType, argTypes) + args)
com_error: (-2147352567, 'Exception occurred.', (0, u'Microsoft Excel', u"Cannot run the macro 'macrohere'. The macro may not be available in this workbook or all macros may be disabled.", u'xlmain11.chm', 0, -2146827284), None)

EDIT

import win32com.client
xl=win32com.client.Dispatch("Excel.Application")
xl.Workbooks.Open(Filename="C:\test.xlsm",ReadOnly=1)
try:
    xl.Application.Run("test.xlsm!testmacro.testmacro")
    # It does run like this... but we get the following error:
    # Traceback (most recent call last):
        # File "C:\test.py", line 7, in <module>
        # xl.Workbooks(1).Close(SaveChanges=0)
        # File "C:\Python27\lib\site-packages\win32com\client\dynamic.py", line 192, in __call__
        # return self._get_good_object_(self._oleobj_.Invoke(*allArgs),self._olerepr_.defaultDispatchName,None)
    # com_error: (-2147352567, 'Exception occurred.', (0, None, None, None, 0, -2147352565), None)
except:
    # Except isn't catching the above error... :(
    xl.Workbooks(1).Close(SaveChanges=0)
    xl.Application.Quit()
    xl=0

I would expect the error is to do with the macro you're calling, try the following bit of code:

Code

import os, os.path
import win32com.client

if os.path.exists("excelsheet.xlsm"):
    xl=win32com.client.Dispatch("Excel.Application")
    xl.Workbooks.Open(os.path.abspath("excelsheet.xlsm"), ReadOnly=1)
    xl.Application.Run("excelsheet.xlsm!modulename.macroname")
##    xl.Application.Save() # if you want to save then uncomment this line and change delete the ", ReadOnly=1" part from the open function.
    xl.Application.Quit() # Comment this out if your excel script closes
    del xl
