In my solution I have two projects. One project contains windows forms and
other user interface stuff. The other project contains data classes and
typed data sets (.xsd).
I've referenced prjFrontEnd with prjData.
I am dragging a dataset object onto the form into design mode. I can select
a typed dataset from its current project, but when I click in the drop down
"Referenced Datasets" and then click the dataset from the other project
(which now show up in the drop down list) I get the following error message.
--
Could not add an instance of prjData.dsMachi neInfo to the designer.
To resolve this problem, build the project, fix any errors, and add the
instance to the designer again.
--
I have done that, and there are no errors in either project but this error
will not go away.
Does anyone have any suggestions?

D,
Did you set a reference to that other project using
Project-> Add References -> Tab projects
Assuming you have added that other project to your current project
Cor
Yep all that was fine.
Funny enough, I re-started the IDE and all worked fine.
I wish I had done that first before writing that long newsgroup post ..

Hi,
I'm trying to write an app that reads data from a table
into a string variable for later use in my program.
Below is a snippet of the code I'm using, which compiles
ok, but at runtime I get and error 'Object reference not
set to an instance of an object.' as soon as I try to
access the data in the fields, I.e. at the line that
reads 'KeyFlags(i) = rstFields("keyflag").value'

I'm not sure if I'm going down the correct route...
I have a class which exposes a number of properties of an object (in this
case the object represents a customer). Can I then use this object to
databind to text boxes etc?
I can't use a dataset as the object has loads of derived logic, for example
updating one property may actually update several database fields for
example.

I have a windows form that was created in the normal way using the form
designer. I do not wish to use this form directly though, I want to use it
as a basis for some other forms. I have added a MustOverride Sub and have
added MustInherit to the class definition. I then created a second form,
this time by adding a class module, and specifying that it inherits from my
first form.
It all works fine, but when I double-click on the...

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
