Hi,
I have defined a module called "Utility Functions" in MS-Access. In
that module, I have defined a function called NullToZero.
I used this function in one of my stored Queries in Access. This works
fine when I run the query in Access itself.
Now, when I call the query from Visual Basic through an OleDbCommand
and an OleDbConnection , I get the exception: "undefined function in
expression"
Is there a special way to call Modules in Access from Visual Basic?
If I call the query from Visual Basic without NullToZero, it works
fine. But, I require that the values updated by my stored query writes
0 instead of Null values. Is there a way out? Or do I have to run the
query and then record by record update null values to 0?
Please let me know. Thanks!

Sorry, not going to happen, you will need to come up with another solution.
If it was SQL server, I woud use the COALESCE function.
When you query a MDB file using DotNet, you are using the Jet SQL engine.
Access need not even be installed on the system being used, therefore Visual
Basic for Applications may not be available, therefore the modules, macros
and forms are totally ignored by OleDbCommand.

Hi there,
I have two scripts. The first "main.py" sets some variables
and then imports another called "gen.py". The idea is to
provide "main.py" that defines some paths, variables etc.
without using Windows environment variables. Various other "hackers"
will make additional Python scripts (subroutines) like "gen.py"
that utilize variables set by the "main.py" and which "main.py" calls.
I can do this with "subprocess" module by setting...

Hi,
I have an Access Data Project (.adp) that I am trying to open and
execute from Python. I am using the win32com.client, and I have
successfully opened the application, but I'm getting an exception when
I try to execute the function (actually a "Sub" that returns void, but
that shouldn't matter). Here's what I have so far:

Hello,
The title doesn't completely cover the question I have, but it's a bit more
complicated problem we have.
We are using a database, based on Acces, but developed by a third party
developer who sells it under his own name. So, functionally it's a very
specific database for a specific purpose.
Now we want to make certain changes in this database, but for reasons of

Hi
I have distributed an mdb file that works fine on my PC using Access 2003,
but when a copy I sent to someone running Access2003 he gets the error
message "missing the intranet or the website".
This is driving me nuts.
Could anyone please shed some light on what is causing this and any possible
fixes. Very much appreciated.

I was asked to provide a proposal. I provided a proposal on my application
and the prospective client likes what I have but is wary of it having been
developed in Access.
I don't understand this concern since my front-end application will be linked
to a SQL SERVER backend.
But there seems to be this "conventional wisdom" among IT people that Access
is a toy database. Okay, let's redefine that as "Jet" is a toy database

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
