Invalid Class String

Are you getting the error below?

Server objecterror 'ASP 0177 : 800401f3'

Server.CreateObject Failed

Invalid class string

This error will usually be caused by one of two things...

A mistype in the Server.CreateObject method
-ex
-set conn = Server.CreateObject("adodd.connection")

as you can see, the adodd, should be adodb
Another possible cause, would be trying to use an object that has not been installed on the server.
-ex.
-set obj = Server.CreateObject("some.class")

this would give you the error because more than likely, you don't have some.class installed on the server. A real world example of this would be trying to use JMail this does not come installed on servers, and must be downloaded and registered for it to work.

The first one can be solved by carefully going through your code to try to catch the mistype. the second one must be dealt with by the server adminstrator.

Yes I have got this same error on windows NT server (option pack 4.0) I' moved the files to another server running windows 2000 and its working, so its not the script. Are you able to point me in the right direct as to correcting the problem. I obviously need to check the components installed plus install the needed one - how?

well, lets start with this... What are you trying to instantiate?
Chances are it's some kind of mail, upload, or xml component that hasn't been installed on that server. You need to get in contact with the administrator of the box to install whatever you're trying to call

I have checked the code against the sample on this website (from Martha Graham) and mine matches.

Dim objCDO

Dim from, mailto, Subject, Body, redirect_url

redirect_url = "tenrox_thanks.asp?pdf_file=" & Request("pdf_file")
MailTo = "tenrox@rodbard.com"
Subject = "Tenrox Registration Form - " & Request("BrochureRequested")
From = Request("E-mail")

Set objCDO = Server.CreateObject("CDONTS.NewMail")

objCDO.To = MailTo
objCDO.From = From

objCDO.Subject= Subject

objCDO.Body = Body

objCDO.Send

'Cleanup
Set objCDO = Nothing

Response.Redirect(redirect_url)

I would appreciate any help you can give.

Thanks,

Larry Rodbard
