Hi,
Any idea how to deal with this error, i'm reading from a fingerprint data Bin file and trying to save it as Binary Data Type
---------------------------
Microsoft Dynamics NAV

The expression Binary cannot be type-converted to a Binary value.

OK

Hi Ral,
What is code looked like? Did you use Memory Stream dotnet object?
add a blob field, called e.g. content, to your data table with properties subtype=bitmap and compressed=false.
let's say the data table is called bindata.
use following command to import the fingerprint binary file to the field:
bindata.content.IMPORT('c:\temp\fingerprint.bin');
to read that data from the field, use:
// recNo is the prim. key of table bindata
// variable ch is of type char
// variable file is of type FILE
bindata.GET(recNo);
bindata.CALCFIELDS(content);
IF bindata.content.HASVALUE THEN BEGIN
file.CREATE('c:\temp\fp-out.bin');
file.TEXTMODE(FALSE);
bindata.content.CREATEINSTREAM(inStream);
WHILE NOT inStream.EOS DO BEGIN
inStream.READ(ch);
file.WRITE(ch);
END;
file.CLOSE;
END;
