Hi,
I have a problem that might be easy to solve(possibly, I've just overlooked
an easy solution). Here we go:
I have a dataset with 2 datatables in it. Now, I need to do the following:
if ds.table(0).rows(0).item("col1") = ds.table(1).rows(0).item("col2") then
txtResult.text = ds.table(1).rows(0).item("col3")

Hi,
I've got a simple console app that just reads an XML file into a DataSet
then prints out a description of each table in the DataSet, including
column names and row values for each column. I'm getting some strange
results depending the input XML file I use. I was wondering if somebody
could help me understand what is going on or point me to a good reference.
The code for my program looks like this:

Hi,
I have an app that uses a typed dataset to persist user data. The dataset
has a multiple tables with multiple table relations. The problem I am
running into is that the user data is dynamic and is not predictable at
design time. What I mean by this is the forms that user inputs data is not
static - it changes dynamically at runtime based on user input. This makes
it difficult to persist the data in a dataset with multiple...

I have a dataset with multiple data tables. I need to bind this to a wizard
interface, where each portion of the wizard udates the information in one of
the datatables. I am using formviews in each screen of the wizard since this
seems to be the only way to databind anything in ASP.Net 2.0. I could not
set the datasource to go against the dataset directly, since the methods to
populate the dataset are in the dataadapter objects, and...

The code i'm writing is using VB .NET and is for a web service returning a
dataset, which is in turn to be used by an ASP .NET application displaying a
datagrid.
I'm currently populating a datagrid using a "select top 1 column 1, column2,
column3 from tblTable" statement. As there will only ever be one row
returned I want to be able to to switch the column names to be row1 and the
column values to be row 2
i.e. select house, street,...

I want to list all of the items in a dataset in a textbox. The dataset
has multiple tables. When I try to use the code below, even though I
dim myState as the DataTable("state"). It still looks for othe rows in
the dataset.

I have a function that creates a DataSet, populates its many DataTables and
then returns the DataSet.
I want to bind separate controls to each of the DataSet's DataTables, e.g. a
separate GridView for each DataTable.
As far as I can tell, the ObjectDataSource only binds to the DefaultView of
the DataSet's first DataTable. I'd like to know how to bind to the other
DataTables or, if this is not possible, what alternative technique is...

Hi Guys
Is there any way in c# (or vb.net) to extract a datatable of data from a dataset with multiple datatables which has relationships set up (containing combined data from the datatables)?
I currently have 2 datatables in the dataset. The first one contains the header records with columns such as Id, DateCreated, DateModified, etc
The second datatable contains the detail records and has columns such as Id, BatchId (which links to...

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...
