18 Days Ago

Hi all,

I have a window service from which i am calling a windows application in c#.
and i am using web browser in window application to get html from a link,
but problem is that web browser's Browser_DocumentCompleted event is firing only first time when service calls application,only for the first page, it is not going on second page,not firing again,

but if we run the application alone it fires till the end of paging....working fine....

but i have to call it from service.
this is the code ---------
