Load access application. (1 Viewer)

Iam new to ASP.NET and its a preriquisite for me to learn it.
I have it running under IIS and VS.NET
Problem:
I have a combobox which has the names of different databases on our server.
I have been told to develop an ASP.NET application to call these applications.
I have button on the page too. What I need is that,when i click this button it loads the access application selected in the dropdown.
This is the far i could get and I cant get going anymore.
Can some one help me please.

Guys help me.
This Javascript functions opens but it brings up the download dialog box.I want to do away with that.

function Database(){
var DatabaseName=Navigator.cbDatabases.value;
if(DatabaseName=="" || DatabaseName==1)
alert("Please Select A Database From The Drop DownList");
if((DatabaseName==2))
location.href='O:/Databases/Contacts3W/Contacts3W v1.mdb';
else
alert("Unknown User details! Access denied!");
Navigator.cbDatabases.value="";
}
