automation object type library reference
 

I am having trouble guessing the data type of some of the
automation functions. I am controlling Excel from a C++
app using excel.exe to create wrapper classes for
Application, Workbooks etc.

example: in C++ the Sheets.SaveAs code reguires before,
after, count, etc as arguments. I know what they all mean
from the VBA object model help; but are they shorts, longs
etc to cast the colevariant you have to use??

Does anyone know where I can get hold of an online
reference so I can look these things up quickly???

automation object type library reference
 

the help file in Excel VBA shows all the arguments to be variant.

In VBA thats the case, however in c++ if you initialize an
application object as "oExcel" for example, then the
following code references a WorkBook (provided oBook and
oBooks have been initialized).

oBook = oBooks.get_Item(COleVariant((short)1));

whereas

oBook = oBooks.get_Item(COleVariant((double)1));



fails, (obvious: but some are not; I was in a hurry) what
I am trying to find is a reference that indicates what
data type each argument is supposed to be. I know one
exists because I have seen it before, but not needed it
until now.

thanks for the reply.
