Resource Availability - MS Project Professional VBA

Hello

I'm creating a custom user form  in MS Project 2010 VBA (the company is using MS Project Server).

The form lets the user find a resource with particular skill set and assign to the project.

I'm using SQL ProjectServer_Published database to get the list of resources and skills available.

Now I'm trying to add resource availability to the form and would need resource work and capacity by day.

I can't find this information in the published database (reporting database is refreshed once a day so it won't be accurate enough)

Is there a way to get this information in MS Project Professional VBA either using SQL Published Database or VBA code?

Regards

Tomek
