How can I select the existing worksheet while using OLE2 to open the template workboo

Question

Source:
application:=ole2.create_obj('Excel.Application');
workbooks:=ole2.get_obj_property(application,'Workbooks');
args := ole2.create_arglist;
ole2.add_arg(args, 'c:\RptTemplate.xlt');
workbook:=ole2.invoke_obj(workbooks,'Open',args);
ole2.destroy_arglist(args);
worksheets:=ole2.get_obj_property(application,'Worksheets');
args := ole2.create_arglist;
ole2.add_arg(args, 'Sheet1');      
worksheet     :=ole2.invoke_obj(worksheets,'Select',args);
ole2.destroy_arglist(args);
Problem:
1. While executing the above code, error -305500 occurs after executing "worksheet := ole2.invoke_obj(worksheets','Select',args)". How can I select the sheet i wanted in the template ??
2. As I refer to the forms on-line document, it stated that the ole2 programmers documentation can provide all object types and methods that can be used with the OLE2. Does any link can provided to download the specified documentation ??

Answer 1

The error is probably that your Worksheets variable is actually empty. Looking at your code I think the problem is that you try and get the value of the worksheets collection from the application then you should try and get it from the Workbooks object.
