the changed datatable in the dataview to a datatable in C#?

hi
i bounded the same dataview to 2 different comboboxes. now, when i change
the selectedIndex of combobox1, it automatically changes the selectedIndex
of combobox2.
does this mean, that the combobox selects the item on the base of some kind
of a pointer on the dataview? if yes, is there a class inside the framework,
which i can use to change this pointer on the dataview myself?
thanx for any hint.

I have a window application. On one of the form, there is a listbox and a
few combox. The lstSchItem has a dataview as a datasource. The comboxes are
bind to its selected value but through the dataset table. Now when I change
the selection in the lstSchItem the comboxes are staying the same and not
reflecting the changes. I tried changing the binding to the dataview.table
but the comboxes are still not changing to reflect the...

I have a window application. In one of the form, a datagrid has a dataview
as its datasource. Initial filtering result would give the datavew 3 items.
When I double click on the datagrid to edit the selected lie item at which
case I would pop up a separate dialog box to do so, in the debugging code,
the dataview.count would return 0. I get a error message because I tried to
get values out of a dataview that holds 0 items. Does anyone...

Hi all, quick question , a DataView is
memory resident "view" of data in a data table therefore once populated you
can close the connection to the database. Garbage collection can then be
used to "clean up" the DataView once it is not referenced and will not
effect the number of connections to the database.
A DataReader on the other hand always maintains a connection to the database
and must be explicitly closed (Do not rely on garbage...

I'm using a DataGrid with a DataSet and I'm trying to filter the data being
displayed, using the following code as a test:
DataView theView = new DataView(theDataSet.Tables);
theView.RowFilter = "'Record ID' = '0'";
theView.RowStateFilter = DataViewRowState.ModifiedCurrent;
Debug.WriteLine(string.Format("RowFilter = {0}", theView.RowFilter));
RecordDataGrid.DataSource = theView;
RecordDataGrid.DataBind();

I have a form with a dataset and a datagrid.
I created a dataview on this dataset.
When the user modifies the datagrid, I look up this record in the dataview
to make sure it is unique.
Here is the confusion.........
I thought that the DataView is the view from the dataset, but it seems that
the dataview has the records that are in the datagrid, because everytime I
search for a record that I know is NOT in the dataset, it finds it. I...

Basically I have a DataGrid that I'm binding to the results of a stored
procedure call. The recordset is fairly small. Initially I'm creating a
DataSet from the results and binding it. There's a DropDownList on my page
that filters the records that are displayed in the grid.
How I'm currently handling this is when I initially bind, I create a
DataView from the table in the dataset. When the DropDownList changes
selection, I get the...

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...

Hello
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...
