HTML Application - Can Javascript Write To A Local Database?

IE 6.0 (not interested in other browsers at the moment)

I have looked everywhere I can find to look and googled until I am
cross-eyed and am hoping somebody knows what I'm doing wrong.

I have an HTML application (.hta) working fine, except one thing. I'm
trying to write to a local database from a .htm window (opened from
the main .hta window) and it doesn't work with any of the combinations
I've tried (and I admit to having tried a lot).

Here is one method I've tried:

strSQL = "Update myTable SET myField = 'myValue' WHERE myID = 12;"
var db = new ActiveXObject("ADODB.Connection");
db.Provider = "Microsoft.Jet.OLEDB.4.0";0
db.ConnectionString = "Data Source='c:myDirectorymyDatabase.mdb'";
db.Open;
db.execute(strSQL);

I can easily access the information in the myDatabase.mdb and display
it on the screen.

I can ask for updated information to be input on the screen.

But stuffing that updated information back into the database is the
problem.

Since I'm stuck in an .htm window, I don't have VBScript available, do
I? If VBScript isn't available and it isn't physically possible with
Javascript, then I'll have to revert to .hta windows, where I know I
have VBScript available. But I'd rather do it all in Javascript
within the .htm so as to avoid the security message that pops up when
the .hta opens a new .hta. For various reasons I don't think it is
possible for me to do this whole project within a single .hta.
