Linking a VB6 and VB.Net Project

I have a system written in vb.net that is a membership system. Also, I have a system that processes finger prints and returns a value (a member number). I need to link these two programs together so that when a finger print is scanned in the vb6 exe, it sends the member number to the vb.net project. This will then show the member.

The VB.Net Project is finished in regards to its function, but a plug-on function for it is to work with finger prints. So I need it to receive the said member number from the vb6 project.

I cant make the finger printing side of things in vb.net as the components I've used are not .net compatible, which would of made my life a lot simpler.

Hope this is in the right place and thanks in advance for any help.

Welcome to the forums. :wave:

How about sending the member number to a database that both programs connect to and read from?

Is there a way to make the programs 'talk' to each other without a middle man (database /file)?

EDIT: And thanks for the welcome :).

Winsock control maybe?

Aren't you already storing your finger print information in a database? Using that would be the easiest and would require the least amount of application programming changes.

The Finger Print information is stored in a specialised file and consists of mathematical algorithms that dictate the identity of each finger print. There is also a separate xml database of member information.

The member id for the xml file is the same as the member id that is related to the finger print algorithm.

you might be able to make your vb6 app an active x exe with a COM interface exposing everything you need. Then you could use interop services to access it from dot net.

Thanks for that idea... It might be worth a look at.

However, how can I go about sending information to and from vb6 to vb.net through winsock controls? I have tried and cant get it to work.
