Can anyone tell me the best way to update a dataset while it is being
edited/viewed in the DataGridView control? Is this something that
should be inserted into one of the grid's events? or should you update
after closing the grid/form, etc.?
Also, can you tell me the best book to buy that fully explains the
DataGridView control?
Thanks.

Hi all
I have a datagridview, and I want it to show and enable editing of a
table in my mysql database.
I get the results from the sql-query into the dataset, and when I view
the dataset in the debuger with the dataset viewer, I can see that the
dataset is filled with my data, but the datagridview is all grey,
showing no columns and no data.

button to save the data to an XML file.
When they click on Save, I call the subroutine below. The first time
that I call it, it works fine. However, if the user makes some more
changes in the DataGridView and then wants to save again, I get the
following error message:

Hi everyone,
I have a strongly typed dataset, with my main form having a datagridview that is binded to an access database. The main form has three buttons one to create a new entry in the database one to edit an entry in the database and one to close an entry in the database. All three buttons work in the similar way, such that the entry you select in the datagridview is the entry you want to close or edit. When I click on the open or edit...

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
Here is the code in...
