Thank you for your answer.
I actually tried the data types we use int, double, Variant_Bool. They
work fine. We do not use VARIANT or SAFEARRAY to limit porting effort to
other platforms.
The String type does not work correctly. Do you use a BSTR in Unicode
character set? Where can I find information about the string data type
used in ooBasic? Is there an example in the OpenOffice documentation about
the use of the string type during library calls?
What would be a simple example of ?functions in one IDispatch object??
The examples with IDispatch in the openOffice documentation and
development kit are using the syntax like
mgr = getProcessServiceManager()
o = mgr.createInstance("org.openoffice.sheet.addin.RNG")
from the simple Calc Addin Example
(http://wiki.services.openoffice.org/wiki/Calc/Add-In/Simple_Calc_Add-In)
How would the IDL with one dispatch object like in my case.
Thanks in advance for your help.
