Programmatically setting folder/file permission for sharing folders

I am trying to find a way of sharing a folder on the computer as a network share.
This is very easy done manually, but I need some help in finding out how this can be done programmatically.

I need to do the following (ASAP........)
1. Set a specified folder as a network share including access permissions.
2. Set the different properties for files/folders in the share

How can this be achieved?
Could somebody help me with some code examples?  Preferably in VB.NET, but C# is also OK.
Or links to pages that give this information?

Thank you for your input!

The last sample is working and is able to create the share, however I don't understand how to set the different security settings of the folder.
It needs to be different for different users. It only shares the folder with full permissions for all, and that is very risky......

I found this info, but that was all:
In SHARE_INFO_502 structure you can specify the permissions by specifying a Security Descriptor that has the required ACL. If you set the value of shi502_security_descriptor variable to 0, then a null DACL is set on the file share meaning that Everybody has full access to this share.
