Hi there,

I am working on an application where I need
to insert a Bitmap in an Access 7.0 Table
throw DAO under VC++4.2.

Does anyone know how to do such a thing ???
Any piece of code or any helpful information
would be great.

Thank you,

Hi there,
Here is the solution for what you asked, I faced the same problem few months
ago.
Bitmap are considered Binary data, and DAO needs data to be in COleVariant to
be inserted.
Now, what you need is how to convert binary data( Bitmap) to COleVariant and
vice versa.
There is a very helpful Microsoft KBase article that has the title" How to
access Binary data using dbDoa" (PSS ID #: Q152294) under the ( C Compiler )
topics.
And because you are working on Win95 (32-bit) you need to modify the line
that use memcpy to be CopyMemory and this is the 32-bit version of memcpy !!!

Enjoy and best regards,
yours
