hi
i have a problem with System.Data.DataViewRowState.
i have a ReadOnly datagrid,
a dataView and a dataTable.
i'm using the dataView's filter property to filter the data (firstName =
'Dani').
the problem is that i don't understanh how the ViewRowState works:
i have an external form that changes the value of the dataTable.

We've suddenly started getting a problem with a call to clear the contents
of a DataTable. This is on a live customer site that's been working fine
until yesterday. As far as we know they've not changed or updated the
server in any way.
"There is no row at position 42"
at System.Data.RBTree`1.GetNodeByIndex(int32 userIndex)
at System.Data.DataTable.Clear(Boolean clearAll)
at system.Data.DataTable.Clear()

Hi,
I am working with strongly typed datatables.
What is the most efficient way to build a new DataTAble based on the result
of DataTable.Select?
At this point I use a foreach loop to do the work manually. I am looking for
an automated way.
Thank you,
Max

I have a function that creates a DataSet, populates its many DataTables and
then returns the DataSet.
I want to bind separate controls to each of the DataSet's DataTables, e.g. a
separate GridView for each DataTable.
As far as I can tell, the ObjectDataSource only binds to the DefaultView of
the DataSet's first DataTable. I'd like to know how to bind to the other
DataTables or, if this is not possible, what alternative technique is...

Hello,
I have a Gridview control (.net 2.0) that I'm having trouble getting the
Update button to fire any kind of event or preforming the update. The
datatable is based on a join so I don't know if that's what's causing the
behavior or not. It seems like the Update button should at least do
something.
When the Edit button is clicked, the grid goes into Edit mode and the Cancel
button takes the grid out of Edit mode. So, I don't get what...

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...

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
