I am learning to program C++ .net and am having difficulty with one of the
exercises and wondered if someone could help?
I am including the code for a console app I wrote according to the exercise
that is supposed to create a connection to the
Northwind.mdb database. I modified the code for the ConnectionStrin g to
include the path to where I found Northwind.mdb
to be located on my machine. When I run the program, I get the following
error:
An unhandled exception of type 'System.Invalid OperationExcept ion' occurred
in system.data.dll Additional information:
The 'Microsoft.Jet. OLEDB.4.0: Data Source=C:\Progr am Files\Microsoft
Office\Office\S amples\northwin d.mdb' provider is not
registered on the local machine.
Can anyone help me?

Hi,
You have a bug in your connection string:
S"Provider=Micr osoft.Jet.OLEDB .4.0:" ...blabla
There should be semicolon instead of colon
S"Provider=Micr osoft.Jet.OLEDB .4.0;" ...blabla
Hope this helps

Hello,
I am trying to learn how to manipulate a table via a Windows Form in vb
..NET. I am able to create the form1, and in the load event, I can put in the
necessary ADO connection statements to query Northwind. So the environment
is set up correct.
Can anyone point me to an example where I can enter search criteria from the
form, and get the results back and display them, or update them from the main
form? I can't seem to find one.

Can't open Northwind
I remembered doing walkthrough using Northwind. However it wasn't an http
project but a file project using the development server. Northwind allowed
me to add, edit and insert, and the web page looked fine.
I opened a simple project just to see whether I could get my sqlserver on
the internet. (vs studio 2005, sqlserver 2005)

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows.
