Hi all, I've been trying to understand exactly how to insert a newly created
DataRow into a DataRowCollection at a specified row value without much luck.
At first I was just appending the collection with the Add method. That
worked fine, but not the InsertAt method. It always inserts the new row at
the end, just like Add did. Thanks for wathever help you can give.
Cheers,
Derrick

Hello,
I am trying to use the find method to locate a particular record in a
table. The code is :
objectfindTheseVals = new object;
findTheseVals = station_ID; // an integer
findTheseVals = dt; // a datetime
DataRow foundRow = dsStationDays.Tables.Rows.Find(
findTheseVals);

I have sub classed the DataRow class and added the IComparable

When calling the Find function of a DataRowCollection, one has two options:
Overloads Public Function Find(ByVal key As Object) As DataRow
or
Overloads Public Function Find(ByVal keys() As Object) As DataRow
This function is easy to use if the primary key of your DataTable consists
of only one field. How can you use the Find functions if the primary key
consists of two database fields (composite key)?

Hi all,
I have 2 asp .net 2.0 projects currently being developed. One is in
VB .Net and the other in C#. In the VB .Net project I can cross-reference
a datatable object using the datatable.rows.item(i).item(j) , but in the
C# project I can not do it. That is, I do get:
error 'System.Data.DataRowCollection' does not contain a definition for
'Item'
They are running under the same development evironment. (i.e. Asp .Net 2.0)

Hi,
my name is Iram.
I'm upgrading my winform application which was developed
in .NET 1.1 to .NET 2.
There is a code section that works well in .NET 1.1, but in .NET 2 raises an Exception of:{"Object reference not set to an instance of an object."} System.Exception {System.NullReferenceException}
The code is:
DataRowCollection rc;
DataRow newSearchRow;
rc = searchQuestions.Rows;
newSearchRow = searchQuestions.NewRow();

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...

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,...
