Visual Studio VB.NET Global ADODB.CONN -

-

i building application requires me query as400 database 100 times per single use.

i have functions each of queries right written in following structure.

option explicit on shared function query1()     dim conn new adodb.connection     dim recordset1 new adodb.recordset     conn.open("databasename")     recordset1.open("select * table",conn)      return somevalue end function

my application runs pretty slow, around 30-40 seconds. i've done performance profiling using tools built visual studio 2013 , noticed repeatedly opening connections database taking significant portion of time.

my question is, can set global connection variable @ top level of routine have open connection once, , close once routine finished queries? think speed application?

something following:

option explicit on global conn adodb.connection conn.open(dsn = "database")  shared function query1(byval conn)     dim recordset1 new adodb.recordset     recordset1.open("select * table",conn)     return somevalue end function

thanks in advance !
