I use PB will excel import database, using the OLE and in the global variable declaration oleobject excelserver, but the problem when running
Error: null object reference at line 3 in the selectionchanged event of object ddlb_sheet of w_excel
Why is that? Who can answer? Thank you very much!

Oleobject excelserver 
Excelserver=create oleobject object creation//? 
Excelok=excelserver. Connecttonewobject (" excel. Application ") 

If it is imported into the DW, and saved to the database, you can also use ImportFile function import 

String null_str 
SetNull (null_str) 
Ll_rtn=dw_detail. ImportFile (null_str)
