Hi Experts,
Looking for a very quick bit on of advice on how to make some python
code run. I'm a newbie to both VBA and Python, so i apologise if this
is very easy but i'm about to tear my hair out after googling for the
last 3 days.
I have written a large python script which inside of it creates an
Excel table, the name of this file and how many objects can change for
each project i run.
I have then written a VBA script which takes the info from Excel and
drops it into a PowerPoint Pres.
Both of these procedures work fine, but i am coming unstuck when i try
to apply the macro, (or .xla) file to the new tables autmatically. Can
anyone give me any guidance on this?
The macro is called sub is CTP and the add-in file is CTP.XLA
Below is the code i've managed to 'Stick' together
Mike
import win32com.client
xl = win32com.client.Dispatch("Excel.Application")
ppt = win32com.client.Dispatch("PowerPoint.Application")
xl.Visible = 1 #open MS Excel
ppt.Visible = 1 #open MS Powerpoint
xl.Workbooks.Open('Z:\\projects\\surveys\\SPSS - Generic files\\big
output.xls') #A table for a project
xl.Workbooks.Open('Z:\\projects\\surveys\\SPSS - Generic
files\\CTP.xla') # Stored macro add-in
ppt.Presentations.Open('Z:\\projects\\surveys\\SPS S - Generic
files\\Basic Template.ppt')
xl.Application.ExecuteExcel4macro('CTP!CTP.xla()"[big output.XLS]')
It doesn't really make sense to apply a *file* to a *file* - you apply
a sub or function in that file to a range in the other file (I'm
assuming that your table is stored as a range of cells). What
ExcecuteExcel4Macro is expecting as input is a string along the lines
of
'CTP!MacroName(Workbooks("big output").Range("A1:C100"))'
(experiment with using "" instead of " since VBA requires embedded " to
be escaped by "" - but since you are writing this in Python it might
not be necessary). Maybe experiment with writing a VBA macro in Excel
which can successfuly launch the macro you need and then translate the
appropriate snippet to your python script. Also - are you sure that the
add-in macro is an old-style Excel4 macro? That would make it about 10
years old or deliberately retro. If not - the run method might be more
appropriate.
You should probably open the workbooks in such a way that big
output.xls is the active workbook (and not ctp.xla) since most add-ins
assume that the calling workbook is the active workbook (although - I
don't know how an old-style pre-VBA Excel4 macro handled things). Thus
you would probably want to open big output.xls last (or use
xl.Application.Workbooks("big output").Activate ) to make sure that it
is the active workbook. Also - do you even have to open ctp.xla
explicitly? If it is an installed add-in then that line might be
redundant.
A final potential problem is that big output.xls might require a
reference to ctp.xla. This sometimes happens when you try to invoke
add-in code from another VBA project - but I would think that the
ExecuteExcel4macro would bypass that.
I can't comment on the python part of the equation - I am a complete
newbie there.
You might consider reposting this in microsoft.public.excel.programming
since many of the regular posters there know a lot about automating
Excel from scripting languages. They could at least help you with the
VBA side of the equation.
I hope that my random thoughts don't misguide you too much.
