How can I easily add the rows of DataTable1 to the rows of DataTable2. Both
queries are from the same table. I can always use the column names with
myRow, but I was wishing for a shortcut. When I try this it doesn’t
work.
for (int i = 0; i < dataTable1.Rows.Count; i++)
{
myRow = dataTable2.NewRow();
myRow = dataTable1.Rows;
dataTable2.Rows.Add(myRow);

Hey all,
I am very new to ASP.Net (and .Net in general), but that isn't stopping the
boss from wanting to begin new projects in it. This latest project has me
kinda stumped and after a couple days of struggling, I figure asking you all
(the experts) will keep me from going down some dark and dangerous road.
The project I have is a fairly simple one, in theory anyway. The gist is to
create a page where the user enters an IDNumber,...

I have an untyped datatable that has financial numbers and controls that
were populated by code (not a simple fill from a DA). Now I want to insert
subtotals into it. I wrote a sub to do so that uses InsertAt(myrow,i).
When I trace through the sub it is doing the insertat and the value of i is
correct. But when I bind my dataset to a datagrid all of my inserted rows
are at the end? code is below.
What am I doing wrong?
thanks,

I have something strange going on.. My .aspx page contains a file upload
control, a "Import Data" button, a "newTransactions" <asp:table>,
a"SaveTrans" button and an confMsg label.
First the user selects a file, then clicks Import Data. The page now reads
the PostedFile and displays each line as a new row in the newTransactions
table. All of this works fine.
For now, I've programmed SaveTrans_Click to display the number of rows in

I have a DataList on my page which contains multiple DropDownLists. My
page defaults to showing six rows in the DataList. I want the ability
to dynamically add rows if needed. Right now I'm just using an empty
table with X rows, and adding a new row to the table that the DataList
is bound to. However, I can't figure out a way to do this and at the
same time maintain the current viewstate of the existing controls.

I modify a single row in a DataTable By setting the FirstName column in a
specific row to another name. ( Without Accepting Changes ).
However, this statement still returns the rows with the 'New Value in it'
shouldnt it be the values before I made the change or have I missed
something.
r = Ds1.Tables(0).Select(Nothing, Nothing, DataViewRowState.OriginalRows)

Hi all,
Would someone be able to tell me the most 'graceful' way of removing
unwanted rows from a dataset based on a condition prior to update? OR,
resetting the rows all to unchanged after they are initally added to the
recordset.
I create a dataset, which begins empty after the initial .Fill.
Then I create several rows with some default information, leaving one

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:
