How to drop Blobfields into Explorer
hi friends,
i need a step by step explaination about:
i have a blob-field and a field with the filename in a table. i wish that the user is able to multiselect rows in a dbgrid and drag them on the explorer.
after dropping there, the blobs should extracted from the table and created as file with the filename in the directory, where the drop finished.

well,
have checked out the
dragdrop-components from melander,
and have done a test with the TDropFileSource-Component.
this works proper enough for my needs,
and was easy to implement.

well done hubdog,
congrates to your first 1000 expert-points ;-)
