Hi,
I have an Excel application which loads DLL when opened.After making some DB
operations it emails itself by using MailLogon and SendMail methods.(Actually
DLL code makes these)
This works perfectly.
Now my problem is,
I want to make an ASP.Net application and when user clicks a button , I want
a BAT file to be activated and open this workbook.Everything is fine.But When
excel file finishes all operations and tries to Logon mail system (which is
outlook) , it gaves an error "Exception from HRESULT: 0x800A03EC" . This
problem does not occur when I double click BAT file by myself it sends email
but does not send when I run this BAT file from ASP.NET .I think I am missing
an update for MS EXcel but I can not handle it.Does anyone have any idea?
I am in a deadlock!!!

Thanks in advance.
