Hi
I'm creating a dataview "on the fly" in order to sort some data prior to writing out the information to a MS SQL table
I have used two methods in order to determine the sort order of the DataView. (I'm writing in C# with the v1.1.4322 of the .NET Framework, in Window2K server"). First of all, here are the two methods I have used in order to apply the sorting property to the DataView
1. Simply defining the sort order and colum

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...

Based on a prior posting, I've written a function to convert a
recordset to a dataview. The first call to the function for a given
recordset works perfectly, but the second call always returns a
dataview with a count = 0. Can someone explain why and how I might
work around this problem?
Here is the code for my function:
Public Shared Function GetViewFromRS(ByVal pRS As ADODB.Recordset) _
As DataView

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...

I want to create a dataview with a sort on multiple columns. However,
when I use FindRows, I only want to search some of the columns, not
all. Is this possible? I have not been able to make it happen.
Dim objKeys(2) as Object
objKeys(0) = "CL"
objKeys(2) = 4000

I have a datagrid that is two levels down from the dataview (i.e.
grandchild). I have spent 3 hours trying to get the syntax of determining
it's real datasource (i.e. not it's source based on it's relationship with
the dataview).

I'm trying to find a way to keep from having to fill a DataView after
every PostBack to a page. Basically, the design is that I have a
DataView that I fill, which I then set as the DataSource to a DataGrid
on my page. This works well, however, like I said, I would like to
keep from having to fill the DataView on each PostBack. So, naturally,
what I did was checked whether or not the request was a PostBack by
checking the IsPostBack...

Hi All,
I am using .net framework 1.1 and c#. I have one problem regarding dataview.
I have one dataview to which sorting may be applied or may not be applied. I have one UI component where I am displaying the dataview. All rows in dataview are displayed in the sequence as they appear in dataview. i.e. there is direct mapping between dataview rows and UI rows.
I have subscribed ColumnChanged event of the datatable on which dataview is...

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

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,...
