<HEAD>
<TITLE>ASPHole - Fill List Box Example</TITLE>
</HEAD>
<BODY>
<FORM METHOD=POST>
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>
<INPUT TYPE=SUBMIT>
</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If you have problems running this script, your database drivers may be out of date.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
