How to return a database connection from a function?

Question

I need to modify some legacy code that was written in classic ASP (VBscript).

I have a line that sets a database connection like this:

set m_conn=OpenConn()

I believe that the OpenConn() function is in a DLL somewhere. This is bad news because we can't locate the source for that dll. So, I've been working on a replacement for that function. This is what i have so far:

function OpenConn()

dim conn
set conn = server.CreateObject("adodb.connection")
conn.open "XXXXconnection-stringXXXXX"  
OpenConn = conn

end function

When I try to run the original line set m_conn=OpenConn() (line 50) I get an ASP error:

Microsoft VBScript runtime error '800a01a8' 

Object required: '[string: "Provider=SQLOLEDB.1;"]' 

/path/to/include.asp, line 50

I'm not too clear on how this syntax is supposed to work. Usually, I work in C#, but when I need to do things like this in ASP I'd use syntax like this:

set conn = server.createobject("adodb.conection")
conn.activeconnection = "connectionstring"
conn.execute "sql"
set conn = nothing

Anyway, I'm looking for the correct syntax for OpenConn() so that set m_conn=OpenConn() will work correctly.

Thanks for any help.

After a little more poking around, I figured it out.

The function definition should have been:

function OpenConn() 

    dim conn 
    set conn = server.CreateObject("adodb.connection") 
    conn.open "XXXXconnection-stringXXXXX"   

    set OpenConn = conn  ' change - added "set"

end function
