I am writing a fairly Maths-intensive application for an Engineering firm and am trying to based it on a database. I am using class modules to tie in with each table in the database and use the following code to connect (copied from COM tutorial 2):
I am trying to keep the number of global variables as low as possible. If the class module is called Joint then for example I will put this code locally and pass parameters between subroutines:Code:Private Sub Class_Initialize() Set rs = New Recordset rs.ActiveConnection = "Provider=Microsoft." & _ "Jet.OLEDB.4.0;Data Source=" & App.Path & _ "\CentralDB.mdb;" & "Persist Security Info=False" rs.Open "select * from JointTypes", , adOpenKeyset, adLockOptimistic End Sub Private Sub Class_Terminate() rs.Close Set rs = Nothing End Sub
The program works very well, but it is too slow as it is having to connect to the database all the time and I need a way of keeping the CurrentRecord the same when switching between different subs, modules, forms etc as the program is quite complicated.Code:Dim uJoint as Joint Set uJoint= New Joint
This may seem a really elementary question but remember I am totally new at this (since yesterday when I read the database and COM tutorials)
Thanks
