I have a patent docketing system that's reporting feature is an Access
database. I had to “build†a licensing module into the software and somehow
the new reports etc. that I have generated are not being recognized by the
database.
When I go to Start/Administrative Tools/Data Source (ODBC) and go to the tab
to configure the system dsn, when I get to the drop down containing the
server names, there are three; two with exactly the same name (Argon) and one
that is Argon2.
I was told by the owner’s of the software that to create a new view, I
needed to go into Enterprise Manager and drop the current view and also go
into the Access database and drop that view, then re-create the link to the
view in the Linking Manager. I have done this, but it is not recognizing the
“connection.†When I try to run the report, I get a message saying that it
can’t find the view, but I know the view is there because I can go and look
at the data generated in Access.
I went to Doug Steele’s website, and found an article about making a module
for a DSN-less connection and tried to incorporate that code into my database
and well, although I don’t think I screwed anything up too bad, it still is
not working. If this would work, would it fix the problem with the dsn? I
am sure I didn’t “fill in all the holes†in the code that I needed to, so the
code is not running. This is the code:
Option Compare Database
Type TableDetails
TableName As String
SourceTableName As String
Attributes As Long
IndexSQL As String
Description As Variant
End Type
