    Database Programming using DLL

    Hi,
    for Example
    I have created an activex dll project in vb and opened a class by name class1.Where i have written a function getdb()in this function i wrote the following code which gives the database connection

    public function getdb()
    dim conn as adodb.connection
    set conn =new adodb.connection
    conn.open"dsn="";uid=";Pwd="";"
    End function

    Now i created another class by name class2 in the same dll and wrote a function

    GetRecords(s as double,y as double)as double

    Now i want to use that class1 where i wrot a connection to database in this class to retreive the records.

    Now i created a standard exe project where opened a form and want to dispaly the records which iretreived in class2 of the dll

    How can i do this can any body help me in this regard.
    I want the code and procedure to do this
    I hope the Guirus will help me in this regard

    Thanking You All
    Naveen

    Re: Database Programming using DLL

    put this code on the function getdb()

    set getdb=conn



    now when you call the function is called it returns the connection
    on the function getRecords add this code

    dim gdb as new class1
    dim db as adodb.connection
    set db=gdb.getdb
