Modules & VBA :: Open One Database Form Another And Pass Variable To It

I have a button on my main db, that opens a second db using hte following code:

----------------------
'Dealing with external objects, use inline error trapping
On Error Resume Next
Dim appAccess As Object

Dim db As Database
Dim strAppPathName As String
Dim strAppName As String
Dim strTimesheetPathName As String

[Code] ....

This code works great to open the other db, and handles wheter the other db is already open or not, but I cant seem to pass the variable to the other db using the startup switch /cmd.

I suspect if I used the shell method it would pass the cmd , but I havnt found any way to test if the db is already open with the shell method.

How can I pass a variable to the other db when opening it using VBA?
