Hello,
Thanks for reviewing my question. I am getting the following error when
trying to create a form using the DataForm Wizard:
"The following error occurred: Value cannot be null. Parameter name: type.
I follow the Wizard instructions by creating a new dataset, selecting the
connection and I select the table. When I click the next button I get the
error? Any ideas?

I built a dataform using the VB.net wizard. I have two
tables, with one relation, Parent to Child, linked on one
common key. The dataform loads the data fine, and when I
click on the Add button, it appears to add a record (the
record count goes up) but unlike single table dataforms,
the form does not automatically move to the new record.
In fact, though the record count increases by one (and
you even get an error saying the primary key...

Has anyone noticed that the VS Dataform wizard doesn't gen correctly
DISPLAYED results if you have an IDENTITY key defined for your table
(normal stuff, IMHO)? If your dataset is empty the first "Add" will display
TWO records on the resulting form. This is because they are creating a
'temporary' dataset with the changes; i.e., new record in this case, and
then they MERGE it into the existing dataset, which has a new row defined by

Couple of questions about upgrading an existing installation of VB2003
(Pro) to 2005 (Pro):
1. Not having dabbled in VB2005 yet, I'd feel more comfortable also
keeping a working VB2003 environment available to me for program
maintenance etc. Is there likely to be any problem in doing this?
And, as an addendum to this question and something that may be obvious
but not to me! To what extent is VB2005 tied to v2.0 of the Framework?

I create 2 data OleDbDataAdapters, one with the wizard, and one in
code. I know the adapter created in code is OK because I use it to
fill a data table.
However, when I try to use the same SQL insert statement in the two
adapters, the adapter created with the wizard works fine, but the
adapter created in code gives me an error "Object reference not set to
an instance of an object". The code is below. What am I doing wrong?

I am trying out the dataform wizard in visual studio using a sql server

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:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
