Sorry, for posting again. I checked this site again and did not find my comment. So I thought maybe something went wrong.

I am really sorry.

Hi,

I tried the code and it is working fine as long as the .mdb is specified with an absolute path. But when I try to use only the Database name, because it is located in the same folder as the .htm or when I try to use the Intranetlink it does not work. Does this not work at all or am I doing something wrong?

Best Regards,
Klaus.

Hi,

I found this code and it is working great, when the path to file is specified on an Harddisk. But how can I get this code working with a database placed on the server, e.g. http://myserver/mydatabase/database.mdb?

Anyone who got this working?

Any help would be appreciated.

Best Regards,
Klaus.

Hi Mike,
I was able to run this code locally on windows platform, but when I put it into the server, It didn’t work. I am getting the following message
“the connection cannot be used to perform this operation. It is either closed on invalid in this context”.

Does the connection string need to be specified differently ? I updated the path for the var strDbPath (used /folder/file.mdb), but kept everything else same for var conn_str.
var conn_str = “Provider=Microsoft.Jet.OLEDB.4.0;Data Source=” + strDbPath.

Would you know how to resolve this error. I can be reached at yiu51car@yahoo.com

hi Michael,
You are really great.I was actually struggling for the last two weeks..in other forums ..i was told that we need to use server side scripting even when db is located locally..great effort..and effort appreciated.

Hi Michael,

I know there is a long time to this artical , but realy I need your example
In my application, I’m using js to connect a database. I tested your first code , but when I debugged the source code. A message poped up and said : ActiveXObject is not defined, also for my bad luck the files you have attached to reply Peifang don’t work.
So please if you could send me this files.

Thank you

To Michael Sync,

I have a program that I’ve created completely in javascript (html wrapped in an ebook exe program) that people love except for the fact that they need to complete all the tasks within my program to create their project; many of them have said they would like the ability to input some data and then return to the program and have the program automatically fill-in what data they inputted previously.

I know cookies will not work, because they will not hold enough data; is it possible to have some kind of javascript database within the program that the software could auto write to and auto retrieve from.

I’ve never worked with databases, but if this is something that can be done, I’m willing to pay for it.

Thanks
