VB6, VS6 versus VB.NET, VS.NET compatibility with Access 2000/XP apps

I have Office XP Pro and Developer Edition and SQL Server
installed on my local development machine.

Given the option of installing;
Visual Studio 6.0 Enterprise Edition

AND/OR
Visual Studio.NET Enterprise Architect Edition.
I would prefer to move forward with the .NET but ...

My question is if I use the VS.NET can I design VB.Net
code or standalone modules to be compatible or interact with
existing Access Databases/Office 2000 and Office XP and
Office XP Developer Edition?
I do not have any critical apps that would need to be
upgraded. I just want to write new components and class
modules to let them be used in Access and SQL server apps.

Is it okay -- even advisable to have VS6 and VS.Net
installed on a single local machine with one partition?

I need to install one of these soon. My main use will be VB
for now but web apps later. Your thoughts are most
appreciated.

Thanks,
Maureen

I know of no problems in having Visual Studio 6.0 and Visual Studio.NET
installed on the same computer.
In fact, I am now developing an application with a VB 6.0 "Front End" which
calls a VB.NET dll.
The two Visual Studios are totally separate applications.

Thanks, Turtle.

So any reference to VB6 or VB.net would work with any Access
(97,2000, XP) application -- front end ?
(I realize that this is is a broad and sweeping statement
on my part. Essentially, that is my question.

Pretty broad, indeed.

VB6.0 dll's are made to compile into COM objects, which are generally easy
to call from Access -
although Access gets a bit finicky about the visuals of ActiveX controls
from VB.
If you just want to write calculations, etc in your dlls, you should be
fine.

VB.NET uses a different paradigm from COM for its parts to talk to each
other.
That works great within pure .NET applications, and makes deployment a snap.
However, if you want to call a VB.NET object from "non-managed" code (e.g.
Access), you must make it into a COM object. VB.NET has a couple of wizards
which will do this for you in a couple of different ways -
any "expertise" I may have here gets pretty thin at this point.
I've done it and had it pretty much work, although personally I'm still
struggling with getting events and exceptions across the divide.

Now if you want to have your VB6.0 or VB.NET application call Office
operations, that's a whole different question...

But to get back to your general question -
as long as your VB6.0 or VB.NET "applicatio n" exposes a COM interface,
you can set a reference to it in your Access code and interact with that
interface.

Hi, I'm trying to access the values of properties -- summary and custom without opening Word to do a cleanup op but the customer i'm doing it for only has Office 2000. I'm using c# in .net 2003 and having trouble. I've looked on msdn and can find a pia for Office xp but no mention of Office 2000. Is this possible or do will I have to go back to VS6 and do it in VB?

I have two clients now who want to have an Access 2000 & 2002 application running on NT Server 2000 do some file updating at night when nobody is in the office. I have used Windows scheduler to schedule the apps to start at 4:00 am, but at that time of night, nobody is logged on to the server. Is it possible to get Access to run on a server when nobody is logged on? Many thaks Mike Thomas

I recently picked up a copy of Office 2003, but have installed it (replacing my existing installation of Office XP Pro) yet because... I am in the middle of a client project using Access 2002 with Access 2000 file format (the client has Office 2000 in their offices). I am concerned that replacing Office XP Pro (Access 2002) with Office 2003 (Access 2003) may cause backward compatibility issues. Can anyone comment on this?

When I ordered my new laptop, Sony didn't offer Access 2003 in its bundles. Recently, I have begun to design Access databases using an copy of Access 2002 from my previous laptop. It works fine, but I would like to have all the office apps on the same version. So I have a few questions: 1) Is the file format the same as 2002? Can 2002 users read 2003 files? 2) What are the major reasons for upgrading to 2002 ?

Hello, An ACCESS application (mde) is installed on a computer looking at an mdb file on the same machine. As far as I know the application is installed thru a Wise Installer script. The installation process performs an installation of ACCESS 2000 RUNTIME thru a SAGEKEY script. The application is designed to run only in within the scope of ACCESS 2000 RUNTIME. Everything works fine.

Hello, There is a enterprise web application that is based on asp.net technologies and works on Microsoft IIS. The total number of users is 850. When the load of system gets very high, the system stops working and all users are receiving an error (see at the bottom).

This is just a quick poll for all you web devs out there: What browsers do you test on/are concerned about compatibility with? Obviously, you're going to test on current-generation browsers such as IE6, IE7, Firefox 1.5/2, Opera 8/9, Safari 2, etc. How old must a browser be before you stop worrying about it? Anybody here still test on IE4? Thanks,

I know you guys are heavy duty coders, while I do ad-hoc analysis, and rarely write code.

Hi all, So I bought a new laptop 10 days ago to test my apps with Vista. (home premium) Apparently Office 2007 is pre-installed.

First thing that troubles me of course is 'the ribbon', but my question now is about speed. I opened one of my Access 2000-apps in Access 2007. Speed and...

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
