Re: Passing array of strings
If you care about Automation compatibility (VB6 compatibility
is a goal for example, or scripting languages) then you should use
safe array of BSTR. Otherwise you can use a conformant array:
HRESULT passStrings([in] long sz, [in, size_is(sz)] BSTR* data);
HRESULT getStrings([out, ref] long *sz, [out, size_is(,*sz)] BSTR** data);
You can also use LPSTR and LPWSTR in place of BSTR for the
string type (e.g. C-style ANSI and UNICODE strings). Don't use
char* and wchar_t* explicitly (you can, but you must also specify
the [string] attribute).
Remember to make sure your interface does not derive from
IDispatch and that you do not specify the [oleautomation] attribute
if you use conformant arrays.
