I have a fairly simple form with databound text boxes, but changes (or new
records) are not recognized. The text boxes are successfully populated with
data (from the database) and I can cycle through all the records. Using a
datagrid works fine for updating.
I've based this on the first sample project from the book "C# Professional
Projects" (Premier Press). I've read many posts concerning this (and the MS
KB as well), and most seem...

Hello.
I am developing an Access 2000 form, and I want to populate a
databound list box using a saved query that requires parameters.
Is there any way to do this? I tried creating a DAO querydef
object and setting the parameters, and then assigned the querydef
object to the list box "rowsource" property. This did not work.
Thanks
-Mark

This is driving me nuts, it is such a simply thing to do but i cannot for the
life of me work out how you are suposed to do it. I want to update the data
in DropDownListB based on what is selected in DropDownListA. I am not trying
to do anything fancy with AJAX, i am happy to use Post Backs. If it were two
controls just on the page then i would simply specify a control parameter for
the SelectCommand of the SQLDataSource control which...

I'm using ASP.NET 2.0, C#, SQL Server 2005, and databound controls like the
DataList and the GridView. Right now I'm using SqlDataSource as part of very
quick and dirty site; I'm not looking to tier things.
I want the topmost/first data element in a particular control to NOT be
displayed. This should be possible by either telling the renderer to hide
the first element programmatically, or by deleting it from the data store
that it has...

I am looking for a resource to learn how to do multithreading in a data
bound app. So far, I have figured out that I can't update a databound object
on a worker thread, because that triggers a cross-thread call to the UI
control that it is bound to.
I have created a simple demo to explore the problem. The demo has a
dataGridView control, a bindingSource control, a backgroundWorker control
and a Go button. The grid is bound via the...

My latest problem: I am converting an ASP script that dynamically
generated a table with radio buttons, presented the table to a web user,
then processed which of the items that the user selected.
I already know that I can't use the table, because Microsoft saw fit not
to preserve the data within dynamic tables. After much poking and
prodding, I have managed to create a view (one of probably hundreds I
will have to create to do our...

Hi Team,
Very serious problem with my DB2 V8.1 Fixpack 6 running in AIX 5.1

going down. Several trap files are generated in the db2 diag log

I have a windows client database management application written in C# that connects to remote web services to do all the heavy work. The thin-client app uses strong typed datasets, all maintained at the web service, with a web reference to those datasets via exposed s on the web service.
The client app has a series of windows forms designed to manage particular types of data. For example, there's a manage users form. On each of these...

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

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,...

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.

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...
