group数据窗口 怎样具体读取每个 分组的数据

This code finds the number of the row at which a break occurs in group 1.
It then checks whether the department number is 121. The search begins at row 0:

boolean lb_found

long ll_breakrow

lb_found = false

ll_breakrow = 0

DO WHILE NOT (lb_found)

    ll_breakrow = dw_1.FindGroupChange(ll_breakrow, 1)

    // If no breaks are found, exit.

    IF ll_breakrow <= 0 THEN EXIT

    // Have we found the section for Dept 121?

    IF dw_1.GetItemNumber(ll_breakrow, &

        "dept_id") = 121 THEN

            lb_found = true

    END IF

    // Increment starting row to find next break

    ll_breakrow = ll_breakrow + 1

LOOP

IF lb_found = false THEN

    MessageBox("Not Found","The Department was not found.")
ELSE
        ... // Processing for Dept 121

END IF
