Hello.
       I have the WebMatrix 1.30Mb version with MSDE 1.0.0.0 and
IExpress Setup 1.0.3705.0 .NET Framework. Since I reinstalled my
XP Home OS I cannot write to the database. I can read to, and I
can also manually add data to a database table, but not programatically.
I've asked the ASP.NET forum and they don't know, at least in a form
that a beginner like me can understand. I've tried changing all the
permissions I could access, to no avail. I'm depressed !

Right click the folder and go to properties. You should see a 'Security' tab. If you don't try this:

Open 'My Computer'. Click 'Tools' and then 'Folder Options'. Then click on the 'View' Tab and scroll all the way to the bottom. Uncheck 'Use Simple File Sharing(Recommended)' and click 'Ok' or 'Yes' to the warning.

Once that has been done you should be able to go the the folder where your db.mdb is at and right click on the folder and give <machine name>\aspnet account write access to the folder.

You must be using NTFS and NOT FAT16 or FAT32.

My sincere apologies. I made two stupid errors -
one in the original program and another one in
the test program. All works OK now. Thanks, and
sorry to waste your time.
