Inside VB using Crystal Report

How to Intract with the Crystal Report Data like Report Title and Date. Can I change the Date or title of the field from the Visual Basic?

How can I Calculate the Accumulation of the field in the Crystal Report.
I give the example Below. Here I want the balance Column

Debit      Credit        Balance
100          0             100
0            65               35
70            0             105
0            50               55
170       115               55

Edited text of question.

There are two methods that you can use to sum up your column.
1) Creating a new formula by going to menu item Insert->formula field and specify a new formula name. eg TotBalance. This will bring up the formula builder. Type in:
Sum ({tblProd.Balance})

where tblProd.Balance refers to your table's balance field. Drag the formula to your footer and place it there.

2) Assume that you have a group header and footer defined. Right click on the balance field in the detail section. Choose Insert subtotal and choose the group name. The sum field will automatically be added for you at the footer.

And for your other question, you can use a formula to control whatever is displayed as the field title. Create a new formula and named it TitleCol. In the formula builder, you can change it as you will. Eg:

If {tblProd.Balance} = 0 then

the method above allows you to change the title field to display as balance or total

Good Luck!
