Hi,

I'm wanting to be able to convert data from an OLE object embedded with paintbrush directly to an image stored as binary inside the database.

What we have is a form where any user of the system can come along and place a screen shot of something. I have decided to use an ole object embedded with paintbrush. When they click on the ole object it will open up paint brush, they click edit->paste or ctrl+v. They click close and when they click save I'm wanting to be able to convert whatever data is inside the ole object directly to a collection in the database.

I'm rather stumped on how to do this and/or if it is possible. Is this possible and if so how?


Cheers,
James

I think you'll find that the bitmap will be stored in the OleObject in the oleData property which is an array of OleData objects. I think that you could add a method to OleObject in your schema that would iterate thorught the oleData array and compile a Binary (just add each OleData.block to your Binary and then return it. I think you'll find that this is the bitmap that Paintbrush created. Somebody asked me this yonks ago and I think what I'm suggested should work.

Give it a try and see what you get.

You'll be sidestepping encapsulation etc. and using stuff for internal use so you'll need to consider the usual issues regarding use of unpublished/private stuff.
