I have used this method many a time in previous applications without any
hitches at all and i'm trying to use it in my current application and it
isn't working.
The only difference I can see is that I am using a strongly typed dataset
(and hence datatables and datarows), does that make this function not work?
I figured as my TaskRow inherited from DataRow that there shouldn't be a
problem.
The code, put simply is as follows:

I thought this was weird?? is this a bug in framework 1.0??? (1.0 is the
version I am running against)
---------------------------
dim dtAll as new datatable
dim dtTmp as datatable
dtTmp = LoadDataTable("select top 100 from table...")
for i=0 to dtTmp.rows.count -1
''''ERROR ON THIS LINE'''
dtAll.Rows.Add(dtTmp.rows(i))

Hi,
We are in the process of designing an ASP.NET app, where a user will
enter some 'Customer ID' to be queried in the database. If the ID is
valid, several stored procedures will be called to populate multiple
webpages containing customer information. There isn't a one-to-one
correlation between the stored procedure and a webpage. In other
words, a webpage may have to refer to 1 or more DataTables to populate
itself. Therefore, a...

Hi
Can anybody help me with the following, hopefully simple, question?
I have a table which I've connected to a dataset. I wish to add a new column
to the beginning of the table
and to fill it with incremental values e.g. if the tables looks
like this:

I have written some code to manipulate data/records in a MASTER (order
header) and DETAIL (order details) tables.
What I have written is too extensive to post but essentially trying to:
1. Assign to a datarow (dr1) the first record of the MASTER table
2. Assign to another datarow (dr2) the second record of the MASTER table
3. If dr1.field1 = dr2.field1, then proceed, otherwise do stop
4. Assign to a third datarow (dr3) the first record...

Hi Everyone,
I have been writing xBase applications for many years but I am new to
VB/SQL for larger applications.
In xBase, I would start the main program (form) by opening up all the
datafiles (dbf) and indexes (cdx) that I would need to reference
throughout the application. I would also keep these files open
throughout the application.

We are developing an application (using .Net in MS Studio 2003 using the
Access jet engine as a backend) that is doing quite a bit of number
crunching. The first part of the application was written using collections,
but we have now found that manipulating the data in virtual tables
(datasets) seems a better way to go. However, we have not attempted to
rewrite the previous code to compare the processing of one compared to the
other. Has...

How do I create an array of datarows from a sorted list?
I put a bunch of datarows into a sorted list to sort them. Then I got
an array of the sorted elements. However, I cannot typecast them. I
get an invalid cast error. I notice that in the debugger, that arrays
of datarows are listed as {Length=xx}, but my arrays are listed as
{system.array} and refuse to typecast.
Public Class mySortedList
Inherits SortedList

Hello:
We wrote an entire application where we add our DataRows to our
DataTables immediately. However, we have to shut off our constraints
to do this. We would like to use detached DataRows to circumvent this.
What do you normally do to track detached DataRows? Is there a way to
retrieve them? or do I have to stored them in some temporary location?
Thanks for any input!

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...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....
Now, this would greatly impact the work of software developers. The idea...
