Hi,
Could anybody please tell me why my web application refuses when I use
BindingContext. I am selecting from a database and
if
(this.BindingContext.Count==0)
Server.Transfer("Anotherpage.aspx");
SO that it goes to another page if there were no records meeting the
select criteria but the error I get is
C:\Inetpub\wwwroot\FrontPage\Result_id_search.aspx.cs(157):

Hello,
I know this has been discussed a lot already because I've been searching
around for information the last few weeks.
I'm trying to implement a DataGridComboBoxColumn class. I've found
several examples on the web. They all seem to have problems, though
that I've been unable to resolve.
The most promising example I have found is at:

Hi group. I´m trying to add new records to a sql server data table with:
BindingContext.AddNew();
This sentence clear all my textboxes and not add any record to the database,
the I use the next code, but appears an error about the duplicate primary
key, I suppose that this code is valid if I don´t use the databindings of
the textboxes :
DataTable myTable = dataSetUsuario1.Tables;

Hi,
I retrieved the employee table from the Pubs database into a single dataset
called, dataSet12. I dropped two textbox controls and a datagrid control
onto the same form and bound the controls at design time to dataSet12's
employee table. Now I want to move through the data by pressing a
button....
This code will change the data in the text boxes:
this.BindingContext.Position += 1;

Attempting to eliminate flicker showing (form) and hiding seems to have no
effect as I have it below.
if I move the lines: Me.Show()
Me.ShowInTaskbar = True
f.Close()
to the end of the load procedure the flicker goes away and produces effects
that destroy my multiple binding scheme.
This Line: Me.CurrentDate.Text = CStr(Now) is has a problem with

Hi,
I created a dataform with the data form wizard which
created some textboxes and 1 checkbox. When I add a row
(see section "Add Row" for code) the newly added is not
accessible.
A label "lblNavLocation" generated by the wizard shows
that a row has been added but I can not navigate to it.
See section "PositionChanged" for code.

I have a form with combo boxes, text boxes, and radio buttons bound to a
dataset table (Students) taken from an Access database. The main control is
cboStudents, which lists all the students from the table. The Datasource,
Datamember, and Valuemember properties of cboStudents have been set
appropriately, and the Tag property is set to StudentID, the primary key on
the table. Then I bind the text property of the textboxes and comboboxes...

Just another quick question:
I have the following bit of code:

As Object, ByVal e As System.EventArgs) Handles
cboPasswordListsDepartment.SelectedIndexChanged

I have created a UserControl that encapsulates a third party data grid.
My goal was to create my own DataSource and DataMember properties that
forward the binding to the third party grid, then use binding like
normal.
The problem I am running into is that my UserControl ends up with a
different BindingContext then the ParentForm it is contained in and
thus all other controls on the parent form. (I want various controls
on the form 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:

Overview:
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,...

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.

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...
