Re: MS Access DAO -> ADO.NET Migration

The SQLCe engine requires the 2.0 Framework. Do you have that installed?
What version of Visual Studio and SQL Server is installed? I built database
tables from scripts and wrote my own batch processor to run them. These are
included in the EBook examples.

Bill,

Perhaps you have an answer to the post two lines up.

I have other problems concerning the actual updating of data from my
accumulating DataTable but the basics of defining the tables with
attendant columns in a new SSCE data base are still not completely solved.
However, it does build the SSCE database, just some of the definitions are
not included.

Also, SSEv31VSTools-ENU.exe with the SQL data management utilities will
simply not install on my machine.

I also share your frustration with the Microsoft doc. You'll also find
that Intellisense does not help either. That's because it leads you to
think that specific types, methods, properties and events are exposed when
they are not--you won't find out until runtime. To deal with this issue, I
wrote my first EBook that walks through the entire namespace and documents
how it really works. It's written for developers that are somewhat
familiar with the SqlClient namespace and ADO.NET in general (and those
that have read my Hitchhiker's Guide to Visual Studio and SQL Server book.
This book is available at
http://www.hitchhikerguides.net/EBooks/Titles/5582.aspx.

Incidentally, Microsoft chose to change the name from SQL Server
Everywhere Edition to SQL Server 2005 Compact Edition about three weeks
ago. This version of the SQLCe DBMS engine has been tuned to run in a
Windows Forms environment. It's a fully relational database that supports
a subset of the TSQL SQL syntax. It's easy to deploy (just copy 6 DLLs),
is fully encryptable (so it's safer for data you take to the field) and
has twice the capacity of JET (4GB). SQLCe is also designed to act as a
Subscriber to a SQL Server-hosted Publication. This can make it even
easier to construct a distributed architecture around SQLCe. MS is still
doing work on the Visual Studio and SQL Server Enterprise Manager
development tools but the EBook shows how to get around these limitations
until the next SP or Orcas ships.

Early next year, I'll be publishing the next in my series of EBooks. This
time on SQLCe Replication. I'm waiting for MS to finish work on a new
replication scheme that promises to be easier to use than their current
approaches.

I had your problem basically and am working at the moment to transfer
existing Access 97 databases, (with data), to SQL Server Everywhere, the
new/old database referred to by William (Bill) Vaughn. He suggested to me
that I use this new database for .NET 2005 development where the
DataBase requirements are similar to what I had in a VB6/Access97 desktop
application.

I am working on an app to migrate the Access 97 database to the SSEv
database and it is going relatively smoothly. Although, there are some
problems as I have defined in a post a little above yours.

I do not expect to edit relationships within the predefined database OR
re-define existing tables BUT, I have seen reference to code which can
do this.

If you try to find code samples - do yourself a favor, use Google as
William (Bill) Vaughn valiantly suggests. Microsoft help is, in many
cases, gibberish, which will not solve your query and will just make you
angry and frustrated. I wonder when Microsoft will catch on a construct
a serious library of code samples instead of the meager offerings
available.

If any of the Google search results take you to forums which require
that you 'join', be careful. Some of these forums even want you to pay
to join without you knowing if a solution is actually available there.

Be careful about using Sponsored Links as these must have some financial
incentives involved otherwise they would not be there. It costs money to
put a Sponsored Link on a Google Search result page. Every click means
that money is earned by Google.

If you want to go down this route, use 'Reply to Sender' as well as
'Reply to group' and I will send you my code which is a near completed
application in VB.NET. I do not want to post my email address here.

I need an exchange of info and opinions from another programmer who is
having similar, if not identical problems.

I have an VB6 program that I wrote that access Microsoft Access
databases using DAO. DAO has methods and properties that are Access
specific (such as viewing and editing relationships or indexes on the
tables) I want to write a new version of the program in VB 2005, and I
want to use ADO.NET to access the data. Are there ways of changing the
indexes or relationships of the MS Access database using ADO.NET? Or do
I still need to use DAO to perform these operations?

As a side note, with a few tests that I've done already with some
queries, it seems like DAO is much faster than ADO.NET at running
queries and returning results. I am using the DataReader...does anyone
have any information about the differences etc? Thanks in advance...
