Can you show the code you use to call sqlite3_bind_blob() as well?

You ought to think very carefully before storing anything resembling
raw hbitmap data into your database. You will be embedding obscure
dependencies on windows (vs macos or unix), arcane hardware requirements
such as row lengths being a multiple of 16 or 32 bytes, or whether
the rows are scanned f
Have you confirmed that the pBuffer that would read out is byte for byte
the same as the bmBytes that you used to insert in to the database? If
they are the same, then sqlite did its job (or rather you called it
correctly...), and the trouble is somewhere else.

And what is the type of bmpFile? I guess what I'm getting at here is
that your real issue is more the problem of "How do I serialize a
HBITMAP structure to an array of bytes and restore it." more than "how
do I save it to the database". I think if you can take the database
out of the picture for
Yes I am able to do that. I fill out the BITMAPFILEHEADER and
BITMAPINFOHEADER information for the image, and then I do this:
bmpFile.Write(&bitmapfileheader, sizeof(BITMAPFILEHEADER));
bmpFile.Write(&bitmapinfoheader, sizeof(BITMAPINFOHEADER));
bmpFile.Write(pbyBitmap, size); //pbyBitmap is th
Are you able to load and save the bitmap to a file?

Hello,
I am having trouble figuring out how to successfully write an image to the
SQLite database as a Blob, using C++.
I have an HBITMAP that I would like to be able to store to and retrieve from
the DB. If I understand what I have read correctly, I am supposed to write out
the actual byte da
