I want to fire a database update off of a single change to a single cell in
the datagrid. This apparently cannot be done using keypress, keyup, keydown,
etc. I've read George Shepard's FAQ and while I may have overlooked it, I
have not found an answer. I now am using the CurrentCellChanged event, and
this is satisfactory IF the user moves off...

I am using VB2005 beta and the datagridview is pulling data from one of
three tables in an Access database. For some reason when I edit the feilds

by the datagridview into a separate datatable without having to loop through

the original datatable...

When viewing a datatable in a datagridview one of the columns in it is a
"note" field which can be quite long. I would like to have the note
field of the currently selected row of the datagrid display in a textbox
below the datgridview. I currently have it fixed so if you click on a
row the note field from that row is put in the textbox. ...

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.
