Can't write to Access db

[bamodeo]

I saw the previous posts about using FrontPage, however I have FTP'd a guestbook application to my site that does allow writing to the database without doing anything else. You can see it at:

http://www.joe13.com/guestbook

It came from a web site called webwizguide.com which has some good apps for free.

I scaled it down to a REALLY simple app, so I can understand how to do the programming. My test app is at:

http://www.joe13.com/test

If you enter a user ID of "jdoe" or "jsmith" it tells you that it is a duplicate user ID, which is true. So, I know it is reading the database ok.

However, when I try to create a record by entering another user ID, I get the error:


================================================== ============

Response.Redirect"user_added.htm"

I put in a comment where the code is dying.

My questions:

1) Is there any error handling that I can put in the code so I get more than the 500 error?

2) How do I get this to write to the database. I'd be happy to zip up the app and send it to anyone who is willing to look at it. It is simple as possible. Once I get the basics working, then I'll build a reall application around it.


Thanks!

Oops, the web site from where I downloaded the original application is:

You should see this error once you have done this.

ADODB.Recordset error '800a0cb3'

Current Recordset does not support updating. This may be a limitation of the provider, or of the selected locktype.

Bruce,

Yes, this is the error I now see. Can you (or anyone) help diagnose why? This is a simple application!


Any help is appreciated,

Brad

Your locktype is wrong..

check out this article : http://www.devguru.com/Technologies/ado/quickref/recordset_locktype.html

If you just want a simple asp sample to insert something into the db, see below

<%

Dim cnnSimple ' ADO connection
Dim rstSimple ' ADO recordset
Set cnnSimple = Server.CreateObject("ADODB.Connection")

' DSN
cnnSimple.Open ("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & Server.MapPath("\test.mdb"))
cnnSimple.Execute("insert into tblContact (FirstName,LastName,Email) values ('Peter','lucas','pete@nest.com')")
cnnSimple.close

%>

Hope this helps
