Calling a C++ function from Python

[saleem145]

Hello,

I am trying the following code --

Code: Select all

startDate = spreadsheet.NamedRanges.getByName("START_DATE").getReferredCells().getValue()
endDate = spreadsheet.NamedRanges.getByName("END_DATE").getReferredCells().getValue()
fields = spreadsheet.NamedRanges.getByName("FIELDS").getReferredCells().getDataArray()

service = CreateUnoService("my_module.MyService1")
service.initializeDataset(start_date, end_date, fields)

The last line is failing. Any suggestions. I have the code working from basic.

Thanks,

Saleem

createUnoService is a Basic function, not Python. It is equivalent to the ServiceManager's createInstance() method.

Try

Code: Select all

ctx = XSCRIPTCONTEXT.getComponentContext()
oMSF = ctx.getServiceManager()
oMSF.createInstance("some service")

Hi Charlie,

That's not the issue. I have my own CreateUnoService implemented.

Code: Select all

def CreateUnoService(serviceName):

    sm = uno.getComponentContext().ServiceManager

    return sm.createInstanceWithContext(serviceName, uno.getComponentContext())

BTW: I got the plotting add-on to work.

Thanks,

Why don't you use an object inspector?
Why don't you split up the long lines?

Code: Select all

onames = spreadsheet.NamedRanges
onamed = onames.getByName("START_DATE")

# this fails if the named has relative parts:
orange = onamed.getReferredCells()

# this fails because a range object has no value:
nval = orange.getValue()

ocell = orange.getCellByPosition(0,0)
nval = ocell.getValue()
