CDOSYS.dll and CDOEX.dll problem

ayush patel

Hi everybody,

I wrote a windows service and I have to do sme email functionality in it. I used SMTP and added system.web reference to the project. there are no compilation errors as such but there is a run time error saying

System.Web.HttpException: Could not create an object of type 'CDO.Message'. Please verify that the current platform configuration supports SMTP mail.
at System.Web.Mail.SmtpMail.LateBoundAccessHelper.get _LateBoundTyp()
at System.Web.Mail.SmtpMail.CdoSysHelper.Send(MailMes sage message)
at System.Web.Mail.SmtpMail.Send(MailMessage message)
at export.SMTP..ctor(String filename)

i looked up and realized I need cdoex.dll or cdosys.dll in my project. i could not see both Microsoft CDO for Windows 2000 or Microsoft CDO for Exchange 2000 in the COM references list. But I do have them in my system. I tried adding them manually in the bin folder of my project. But no use.i dont know whats the problem.

i also tried registering them using regsvr32 "\WINDOWS\System32\CDOSYS.dll" and also for cdoex.dll but that is also throwing an error saying

loadlibrary("\windows\system32\cdosys.dll") failed-the specified module could notbe found.

I am using localhost as my SMTP server and it is relaying anonymous messages also. there are no authentication problems.

does anybody know what the heck is happening. its just a simple smtp emial functionality.Service worked fine till friday. it also sent emails.i dont know what happened suddenly.

please help

Do you need to use CDO?
Are you using VS2003? Becuase the SMTP classes moved in .NET2.0 and onward to a different location.

Hi, thanks for replying

I did not think i would need CDO but application throws an error saying

System.Web.HttpException: Could not create an object of type 'CDO.Message'. Please verify that the current platform configuration supports SMTP mail.

all i thought i needed was system.web.mail but i dont know why the above error came up
