Hi,
how can I save the content of a long binary data field from a SQLTable (MS
Access) to a file?
Best regard, Timm.

Use the field value from the dataset directly. Something like:
hFile := FCreate( "SomeFile.dat" )
FWrite( hFile, ::oDataSet:LongBinaryField, Len(
::oDataSet:LongBinaryField ) )
FClose( hFile )

Jose,
many thanks for your answer!
I already tried something similar to your solution but I can´t open
the created file. I expected to get a graphic file (bmp or jpg) but the
file seems to have an other content.
Best regards, Timm.

Perhaps it contains an 'OLE object', that is, an 'OLE compound document'. If
so, I'm affraid it's not an easy task to get it. You'll have to deal
directly to several COM interfaces at low level.
