Still trying to figure out why my vb6 app takes so much longer to process data on a remote server than a corresponding classic asp web page...

How often should I open a data connection with a connection string?  Currently I open it once as the page processes on my classic asp page but I open and close it every time I access data on my vb6 app.  Should I just open it and leave it open on the vb6 app?

Sure, why not? Leave it open as long as you need it.

Ok so then do I declare the variable as a public variable in the main module?

I am a database guy, not much .Net coding anymore, but you should be using some kind of framework that allows connection pooling and opens, shares and closes your connections as needed.  It is true that opening and closing the connection for every database is expensive, so a pool that is opened once or as needed that shares them is desirable.
