Hi Sergei,
Thank you for your reply.
As it is out of my comfort zone, I leave it to up to you (if or when you
implement this)
TIA

It has to be done in a different and more complex way, by using VariantChangeTypeEx to convert the
variant(array) to varOleString type, then converting latter to ansistring.
This way, in Windows the job will be delegated to OS, which is Delphi compatible. For non-Windows,
the relevant code ends up in VariantChangeTypeEx (varutils.inc).
Also, you'll need to access the variant array with SafeArray* functions, and make checks that it is
actually one-dimensional and its element type is eligible for conversion.

Hi,
I am now working on fcl-db TBinaryField, which has Value: Variant
property.
As I understand documentation, this variant should be returned as
variant array of bytes.
Later when are assigning values of fields into params also this
variant array is copied (into TParam).
But when I want/need read parameter value as string (binary string)
then "variant convert error" occurs.
It is because in cvarutil.inc in Function VariantToAnsiString(const
VargSrc : TVarData) is not supported conversion from variant array
into string.
So my question is if it is acceptable to add there support for
converting byte array to string ?
Something like attached diff.
Please let me know, if this can be accepted/applied ?
Thanks
-Laco.
