Hi,
I have a grid on which the Validating event contains a pop up that
prompts the user for yes or no. If the user click yes the event is
cancel otherwise it's not (e.Cancel = True vs e.Cancel = False)
The problem is that if the user clicks no, I would expect things to
keep being processed normally, that is if the user leaves the grid by
clicking on the node of a Treeview and then clik 'No', the node in the
tree should be selected, but...

I was going along fine in my test to see how to manipulate the
DataGrid (dgTrans) and its columns. I have a single form with one
DataGrid (dgTrans) on it. The code I have in my form load event is:
Dim dt As New DataTable("WorkOrders")
Dim colSelect As New DataColumn
Dim colStatus As New DataColumn
Dim colWO As New DataColumn
Dim colEmployee As New DataColumn

Hi.
A scenario has come up in which I'm not sure how to handle. What is
happening is the user enters information in a cell of the grid. If the
user then quits the application as soon as he finishes entering the
data, the data entered in the cell is not saved. I have the following
code in the closing event of the form:
If DataSet.HasChanges Then

Hi all,
I used XMLSpy to validate my XML but it catched one error at a time.
Is there anyway to make XMLSpy to catch all errors at once. If XMLSpy
does not have this feature, what software out there can do this? I
have a very large document with many related files and validating one
by one is a hassle. I want to see all errors and fix it all before
coming back to validate again. Thanks.

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
