Numbering of records in a Group

I just started learnig CR.
1) I want to know how to serially number records which form part of a particular group. "Group Number" gives the group a num and "Record Number" gives a global num. I want each list in a group should have a distinct set of numbers.
Sorry if the question is very silly, I enquired couple of people but no help!

2) I also want to know how do we display a CR from VB and print it to deskjet printer.

Version info:
CR 9 & CR 4.2
VB6Write your own formulas to count them.
e.g. in group header
whileprintingrecords;
numbervar x := 0;

in detail:
whileprintingrecords;
numbervar x := x + 1;|||Like I said in the first instance Iam a novice in CR (that explains my username). Though you have stated to add some variables in group header and increment in detail section, I donot see any "code window" as in VB where I can add the code suggested. I would be happy if you could take some pains to explain me that as well.

Also let me know how to connect, open & print CR9 report through VB6, the database being Access 2003. The connection needs to be dynamic i.e. I should be able to manipulate the connxn programatically through VB6.|||Nobody has responded.
