Hi,
with SetDataBinding( ) a DataGrid shows a DataView. user can select some
rows in the grid by holding cotrol key. when user clicks on Delete button, I
should delete all selected rows. I am trying to delete these lines from the
dataview like this:
for (int i=0; i < dataView.Count; i++)
if (dataGrid.IsSelected(i))
dataView.Delete(i);

Ok, I know how to count the number of selected datagrid rows using the code
below. What has me stumped is how to determine when the selected rows
within a datagrid have been changed. The DataGrid object doesn't seem to
have a any type of a selection changed type of event I can grab.
THE QUESTION: Does anyone know how to determine when the selected row or
set of rows within a datagrid has changed ???
This is driving me nuts !

I'm using Net 1.1 (2003) SP1 & Windows 2000
Here's the issue ...
Rows 12 thru 24 are selected in a datagrid.
The user now unselects rows 12 thru 24 and selects rows 45 thru 70 ???
How can I tell that the user has reselected a different set of rows in a
datagrid.

Ok, I'm currently in a "knock down - drag out" tussle with the .Net 1.1

I've come to realize that a 'block' of rows highlighted within a datagrid do

one row may be 'selected' in a datagrid. By selected row I mean the row

Greetings.
I have a serious problem. I have multiple sets of tables, several of
which are chained more than two tables deep. That is, I have a parent, a
child, and a great-grandchild table.
Currently, I am allowing the parent to be edited by itself. In order to
get to a child table, a user needs to select a specific parent table ID.
I have set this up using panels, and putting a drop-down list in the
first panel, with its contents...

I have a dataset containing a parent table related to a child table. The
child table contains an ID field (which is configured as autonumber in the
datatable), the ID of the parent, plus some addition fields.
I'm able to get the datagrid to be properly populate with only the child
records relating to the specified parent by setting the
..DefaultView.RowFilter property.
Currently, to properly add a new child record, I need to manually...

Question: does datagrid1.isSelected(i) point to the same
row as datatable.row(i).delete after datagrid sorted??
I am using datagrid1.isSelected(i) to identify datatable rows that
have been selected by the user
Then I use datatable.rows(i).delete to delete those rows.
It works fine if I have not sorted the datatable first. But if

Good day Sirs & Madams, I know some of you will find this problem very simple. Kindly share a little knowledge to me on how to deal with this. Thank you.
I have a parent-child table relation. when bsParent is navigated, bsChild follows. In code, I did this to determine the rowstate:
dim dtParent as datatable = ds.Parent.copy
for i as integer to dtParent.defaultview.count - 1
if dtParent.defaultview(i).row.rowstate = datarowstate.modified...

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'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
