Can you issue commands from VB.Net to create and delete databases?
I would like to create, delete, and copy MSAccess tables and/or
databases from code. Can this be done? Can you show, or point me to
some source code? I'm a newbie.
TIA

Hi all,
If I want to provide a typed dataset from a webservice and if that dataset
has relations that are nested (isNested=True), then the relations(keyrefs)
are not available in the XSD that is offered. If I set IsNested to false or
default, then it is included in the XSD.
Is this a bug or by design?

I have a requirement where I need to create a dataset that consists of
a table inside a table ( a child table inside a parent table). I am not
really familiar with the data relations and not sure how to represent
this relation.
I did create a schema and it looks good on paper, but when I create a
dataset from this schema it does not allow me to write to the child
table. I am elaborate more if required.
This is what my schema looks...

Hello,
I am a newbye, and I'm trying to write a simple application.
I have five tables with three columns; all tables are identical; I need to
change some data in the first table and let VB updates the same data in all
other four tables in the right places.
I know it would be possible by using the ForeignKeyConstraint object. I have
created the tables using the DataSet Visual Tool and I know it doesn't

Hi,
I really hope someone can help me out here.
In relation to this thread ( http://www.thescripts.com/forum/thread349557.html ) I'm having a similar issue and getting nowhere fast!
In a nutshell I have a MDI Container which can load up several forms.
Upon loading of a form, I want this form to either access or load a dataset and populate controls that have been bound to various fields of the dataset.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
