A way for c++ code to access records from the UniVerse database?

I know t开发者_如何学Chere is some kind of connection between .NET and UniVerse, by using UniObjects. But I believe that obligates use of .NET, and C# or VB.NET.

Also, I know by reading UniVerse manual that UniVerse can call C/C++ code from within UniVerse, but what I want is the other way around.

1. Can UniObjects be used for c++ project in .NET?
2. Can plain c++ (by plain i mean without using .NET platform) retrieve and store the data from and to UniVerse database?

Yes, although you have to hunt for it.

On the U2 DevZone site Rocket Software has just launched, there is an article about writing a PDO Driver for PHP access. This driver is written in C (iirc) and has all the source code supplied. It uses the U2 InterCall to interact with the U2 system (UniVerse & UniData). You should be able to use this as a way of making calls to the UniRPC process (this is what UniObjects calls).

You have to sign up to the site to access the article & source code, but sign up is free.

There is a library called icsdk. This will let you do just about anything that UniObj would let you do from a java or .NET framework but from C. I don't have the manuals with me to check right now, but if you can get the documentation from Rocket, you want to look up the ICS, or Intercall sections.
