I have a Blob field containing text. I can retrieve the data via IMemoryBlobStream2, but do not know how to view the content. Anyone out there know how to view Blob text content?

IMemoryBlobStream::SaveToFile is the easiest way.

So I have to save to file, then open the file and read it? Is that what you are suggesting?

I can do that. Just seems wasteful, so I wanted to clarify.

Yes, that's what I'm suggesting. What do you want to do with the contents of the blob?

Ok, thanks for the quick response! That's fine. I just need to be able to view the contents, so it seemed like a long way around a short stick.

It's a 1 to N relationship between feature and Blob entries. Therefore, click on feature, run macro, view many blobs of text stored in a standalone table in the same map as the feature class. So I'll have to append the blob entries to the file each time. Ugly. I may do it once, so I don't have to constantly open/write/read files.
