hi,

I have created a little time reporter (Web Application) that has a button to export time sheets to excel.

when I debug the application by hitting F5 and then I click the button to export time sheets to excel, everything goes well but when browse to my application (http://server:888/app1) the button does not work and it generate followin exception:
System.Exception: Cannot create ActiveX component.

it generates at this line of my code:
oExcel = CreateObject("Excel.Application")

Hi Medes

this forum is specific for questions concerning the VSTO technology. You're automating Excel in a web application, which is outside the scope of this forum. You need to ask this question in a more appropriate forum, one that deals with web issues. The ASP.NET forums are here

FWIW, from what I've seen discussed here-and-there, you're probably running into Security problems. Perhaps Internet Explorer isn't set up to allow what you want to do?
