I've got a similar problem. I want to save a bitmap in a long raw-field in a ORACLE db. I don't know

1st) how to read data from this long raw field
2nd) how to show the bitmap in a picturebox or in an image
3rd) how to write data of a bitmap into the long raw field, so thet i

can read it later on.

Thanks for help
