Hi all.
I have two database blob fields - IMAGE and THUMBNAIL.
I use TImageEnDBVect an i need to every time before
post image to DB, create small thumbnail (bmp or jpeg)
an save to THUMBNAIL field ...
Without anotations, only clear image to thumbnail.

But cannot find right way how to do this ...
Any ideas ?

Hi

You should be able to use the table events to determine when a change has been posted to the database (or do it when user clicks "Save" for example).

Then create a thumbnail from the TImageEnDBVect IEBitmap and post it to the database. Thumbnail methods are available in iexHelperFunctions:
