<BODY>

Country: <SELECT NAME="Country">

' Construct path to database

sPath = Request.ServerVariables("Path_Translated")

sPath = Left(sPath,InStrRev(sPath,"\")) & "Countries.mdb"

' Open Connection & Recordset

set oSample = Server.CreateObject("ADODB.Connection")

oSample.Open _

"Provider=Microsoft.Jet.OLEDB.4.0;" & _

"Persist Security Info=TRUE;" & _

"Data Source=" & sPath, "Admin", ""

' Check for default...

mCountry = Trim(Request("Country"))

' Create the List

Set oRS=oSample.Execute _

("SELECT ID,COUNTRY " & _

"FROM COUNTRIES " & _

"ORDER BY ID")

DO WHILE NOT oRS.EOF

mSelected = ""

IF mCountry=trim(oRS("Country")) then mSelected=" SELECTED"

<OPTION<%=mSelected%>><%=oRS("Country")%></OPTION>

oRS.MoveNext

Loop

</SELECT><BR>

</FORM>

</BODY>

</HTML>

Key points of the sample:

sPath is used to construct the path to the database based on the home directory of the script. This means

that the database must be in the same directory as the script., otherwise, set sPath to the absolute path

of the database.

The database is assumed to a be an Access 2000 Database with a table Countries with a character field

Country.

Forms are assumed to point at the same script which created it unless action is specified.

The IF mCountry=... statement is used to insert the word SELECTED into the OPTION containing the previous

country value, should one have been passed in by a submit.

If you have problems running this script, your database drivers may be out of date. Go to
