I thought it was working fine. Then I tried it at home and it seems to be blowing up without any ryhme or reason:<br/> When I right click on the datawindow, it kicks off my event but sometimes ends with "Error: Array boundary exceeded at line 23 in open event of object w_available_drivers"<br/> Here is my code for defining and working with the array:<br/> drvr_req_end_dt = uf_rez_calc_end_datetime(2<wbr/>,drvr_req_<wbr/>start_dt)<br/> datastore ds_1<br/> ds_1 = create datastore<br/> ds_1.dataobject = "dws_get_drivers_from_oper<wbr/>ator_parms<wbr/>"<br/> ds_1.settransobject(sqlca)<wbr/><br/> long rows<br/> rows = ds_1.retrieve(drvr_req_sta<wbr/>rt_dt,drvr<wbr/>_req_end_d<wbr/>t)<br/> messagebox("rows returned before array definition",string(rows))<br/> string rez_drivers[]<br/> string driver_number<br/> long i<br/> long ni<br/> for i = 1 to rows<br/> driver_number = ds_1.getitemstring(i, "dr_no")<br/> ni = i - 1<br/> if not isnull(driver_number) then<br/> rez_drivers[ni] = trim(driver_number) ----IT BLOWS UP HERE---<br/> end if<br/> dw_2.settransobject(sqlca)<wbr/><br/> string day<br/> day = dayname(date(drvr_req_star<wbr/>t_dt))<br/> messagebox("Day",day)<br/> string yes<br/> yes = 'Y'<br/> string no<br/> no = ""<br/> if day = "Monday" then <br/> dw_2.retrieve(rez_drivers,<wbr/>yes,no,no,<wbr/>no,no,no,n<wbr/>o,no)<br/> end if<br/> if day = "Tuesday" then <br/> dw_2.retrieve(rez_drivers,<wbr/>no,yes,no,<wbr/>no,no,no,n<wbr/>o)<br/> end if<br/> if day = "Wednesday" then <br/> dw_2.retrieve(rez_drivers,<wbr/>no,no,yes,<wbr/>no,no,no,n<wbr/>o)<br/> end if<br/> if day = "Thursday" then <br/> dw_2.retrieve(rez_drivers,<wbr/>no,no,no,y<wbr/>es,no,no,n<wbr/>o)<br/> end if<br/> if day = "Friday" then <br/> dw_2.retrieve(rez_drivers,<wbr/>no,no,no,n<wbr/>o,yes,no,n<wbr/>o)<br/> end if<br/> if day = "Saturday" then <br/> dw_2.retrieve(rez_drivers,<wbr/>no,no,no,n<wbr/>o,no,yes,n<wbr/>o)<br/> end if<br/> if day = "Sunday" then <br/> dw_2.retrieve(rez_drivers,<wbr/>no,no,no,n<wbr/>o,no,no,ye<wbr/>s)<br/> end if<br/> dw_2.Modify("r_1.Brush.Hat<wbr/>ch='6'")<br/> Yes, I know there are some horrendous coding techniques shown here, but I am just trying to illustrate the issue. Thanks!! PEM<br/> Now I only added this line the way it is written is because I am passing the value to another window and the help said I had to pass the string as an array. Okay, so now I am learning all about arrays: here is the code:<br/> rez_drivers[ni] = trim(driver_number) ----IT BLOWS UP HERE---<br/> Thank you!!!!<br/> </div><div
