Hi there !
How can I pass one dimentional array to / from COM server ?
Do I have to use SAFEARRAYS to do this ?

An array of what exactly? Different data types can be passed in different
ways.

That, or a Variant array. But again, it depends on what exactly you are
trying to pass in the first place.

For example an array of double or float values

Re:DCOM and Arrays

Take a look at the documentation in safearry.h, located in
$(BCB)\Include\Vcl\
It has examples of creating and reading SAFEARRAYs.
They're quite straight forwardto use...

A Variant array will work for that, but you can use a SAFEARRAY as well if
you like.

Re:DCOM and Arrays

OK.
There's a good document about SAFEARRAYS
"SAFEARRAYs Made Easier" at BDN
