Can I develop Database Applications with the Standard Version of Visual Basic.Net 200

[piscis]

Gentleman:

 

Can I develop Database Applications with the Standard Version of Visual Basic.Net 2003?

 

Every time that I try to open a sample database application that includes an Access Database I get the error shown below, I tried 10 different projects and get the same error.

 

�Object Reference not set to an instance of an Object�

 

Could you please tell me if it is a MUST to install SQL or any other file?

 

I�m Using;

Visual Basic.Net Standard Edition 2003

Windows XP Home Edition

Microsoft Access 2000

 

Thanks

Could you post the code in question please? Much easier to answer that way

um i think this is his question

Personally I was refering to the

 

�Object Reference not set to an instance of an Object�

 

part of the message, as far as I'm aware System.Data is a fundamental part of the .Net framework and as such I can't see any reason why not.

Guys:

 

On my computers folder with this path:

 

C:\Program Files\Microsoft Visual Studio .NET 2003\Setup\MSDE\msde_readme.htm

 

I found this:

 

Visual Studio .NET 2003 does not include Microsoft SQL Server Desktop Engine (MSDE). To download MSDE, go to http://go.microsoft.com/fwlink/?linkid=13962.

 

Do you think that might be the problem?

You shouldn't need MSDE to develop applications in MS Access.

MSDE is a SQL Server compatible database engine and doesn't (shouldn't?) have any impact on other databases.

I'm not developing applications in MS Access. I'm using VB.NET 2003 for developing database applications.

 

Why I cannot open ANY sample database application in VB.NET. I get the error shown above, I tried many different projects and get the same error..

 

Any Idea?

[PlausiblyDamp]

In your original post you did mention a sample project involving an Access Database

Every time that I try to open a sample database application that includes an Access Database I get the error shown below, I tried 10 different projects and get the same error.

hence the reason I mentioned MSDE not being required for Access development.

 

If you are developing for SQL Server then you will need access to either a MSDE or SQL Server based database - in which case the downloadable version would be a valid option.

 

As to the issue of Visual Studio 2003 Standard Edition (Professional?) supports ADO.Net then the following link from MS indicates that it does.

if the samples are opening an Access Database or a SQL database you may need to look at the ConnectionString being used by the samples.
