Re; Do I absolutely need to have Windows XP Professional?

Gentlemen:

Does anyone knows if I absolutely need to have Windows XP Professional in order to open and develop database applications in VS.NET Enterprise edition 2003 (database is MS Access)

I’m using Windows XP Home edition and have tried to open more than 10 database samples and got the same error message on every single one of them. “Object reference not set to an instance of the object”

I tried to build one testing database and when it comes to the part where you choose DATA > GENERATE DATABASE I got another error and the Datagrid will not bound to any table.

Please let me know if the problem is Windows XP Professional. It is anyone out there opening and building databases with Windows XP Home edition?


Thanks

That shouldn't be it at all, sounds like its either your code, or if you are using the wizard maybe a reinstall of VS is in order. Post your code.

Well, not that it may fix your problem, but if you're going to do developing, you might as well get Pro... especially since Home doesn't come with IIS...

Anyway, what database samples are you trying to use? (provide a link)

nemaroller / Edneeis:


These are the steps I’m taking to building a Testing database application:

1- Open MS Access > Blank Database, Place it on the Desktop named DB1 / one single table 5 fields, no records just the structure.
2- Open VS > New Project > Windows Application
3- Open Server Explorer
4- Connect to Database
5- Provider Jet 4.0
6- Go to desktop Select database DB1
7- Test Connection Succeeded > OK
8- Open Data Connection and Drag table to Form
9- Don’t Include Password
10- OleDB Connection and OleDB Data Adapter are created
11- Go to data menu and Generate dataset
12- Select new Dataset 1 and add this dataset to the designer > OK
13- THAT’S when the problems starts
14- I get and error windows that reads

“There were problems generating WindowsApplication2.Dataset1. To resolve this problem, build the project, fix any errors and then generate the dataset again.”

What problems do I need to fix I have not written a single line of code yet? It wont let me. Does anyone know why is this?


Andy

Well the wizard sucks sometimes. Do any of your fields have spaces in the name? Some small things like that choke the wizard sometimes.

Edneeis:

Can I email you only one of the 10 samples databases that are giving me errors too? These are from CDRom-Books

This forum won't let me attach 700k files.

Worked fine for me, might want to reinstall MDAC2.7 or Visual Studio.

Edneeis:


I know that Reinstalling VB is not the issue since I had the same problem with the Satndard edition.

Were can I download MDAC2.7 ?

Andy

Try a search at http://www.microsoft.com for the newest MDAC.

Also on step 11 instead of going to the Data menu try selecting the newly generated dataadapter. Then a menu will appear in the description part of the properties and you can 'generate a dataset' from there. It basically does the same thing as going to the Data menu but it should have your datasources already selected in the dialog that pops up.

Out of VS.NET, only ASP.NET doesn't work with Win XP Home edition. There are few other applications like Oracle Management Server do not work in Win XP Home. This is a problem for developers as nowadays most PCs/laptops come with WinXP Home pre-loaded.

If you are using Visual Studio 2003 Ent. (Dev. or Arch.) it comes with Windows 2000 Server. Just fire a copy of that on with a dual boot, or just 100% switch. 2000 Server is a great OS.
