Hello,
I am having trouble with a datagrid.
I received help online to create the datagrid the way I needed it, so I'm
not entirely clear on how/why it works.
I use the following code to populate the rows of my datagrid.
The variable _arrstr contains my column headers.
For i = 0 To (_dataset1.Tables(0).Rows.Count) - 1

HI all..
I have a huge table that I want to display in a datagrid, the problem is
that if I make a dataset, the entire table must go to the dataset to the
data begin to display, and it takes much time...
I need to start show data after a row pushed to the dataset, so I think
of using the datareader to populate a datatable and bind the datatable
to the datagrid.

I'm sure this is a fairly basic question, but I've been looking all over the
web for days for suggestions on how to do this.
I've got a datagrid that's bound to a dataset on my form. It includes
several columns, the last of which (with the header Quantity) contains int16
values. When a user selects a row, I would like to have a combobox on the
form display the values from 1 to the number in the Quantity column (e.g.,
the selected row has...

I am populating a multiselect Listbox from a dataset, with the content of
the listbox filled by one table, and the selections determined from another
table. So far, I have been keeping the dataset a denormalized mirror of the
database, but I'm not having much luck getting the selection logic down (I
haven't found a 'hook' where I can access the listbox object as an object to
set the listitem's selected property before it gets rendered)..

Hi All ...
I'm writing a small shopping cart app (school assignment) and need to list
all the books that a user selects.
I have created a "BookBasket" object that contains among other things an
arraylist of the user selected books. The "book" object contains isbn,title
price and quantity information.
I'd like to display the contents of the BookBasket in a datagrid control.

Trying to learn about manipulating collections of objects, and populating
these objects dynamically from datasources. Could someone post a code sample
that shows the following:
Instantiating a collection object -- say, a dictionary.
Populating that collection object with custom objects, say, Person. What I
really want to see is how to populate the properties of those Person objects
from a datasource: instantiate one Person, fill...

How do I set field default values at runtime? Say I want a check box
that is bound to a boolean field to default to false for a certain set
of criteria, and then true for others? I also need to do this with other
fields, not just boolean....
Thanks,
Aaron

I am trying to populate a Crystal Report from data in my DataGrid. The
reason for this is that I want the user to be able to change values
without updating the database, but still have their report reflect the
values they anticipate committing to see hypothetical totals of
columns from a set of records. These records are displaying properly
on my DataGrid but I'm not sure how to get Crystal Reports 10 to use
as its datasource the dataset...

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...

Dear forum friends,
With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies. I'm particularly interested in Zigbee because I've heard it does some...

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...

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...
