Come again? I'm not sure what a binary memo is and I'm not sure what part of the process you are referring to? Are you saying that I can convert the binary to memo text, save it to the oracle server and then when I need to download it, convert it back into binary, save as a file and then load it up as an OLE object? I hope so, it sounds like a much better solution.

Cheers, Pablo

But now I am using ADO (+VFP or VB) to get the data back out again. I've had loads of problems getting either language to recognise the format of the data, so I saved the blob as a file. Even this didn't work, but when I looked closely at the start of each file in a text editor there was the fragment Visual FoxPro[Class] e.g. Visual FoxProExcel.Sheet.8.
