I have a form with a single textbox control which is bound to a
DataRelation in a typed dataset. The textbox displays the name of the
product depending on the language selected from a combobox. When you
select a different language, the textbox must show the name of the
product in the selected language. This is done by setting the RowFilter
property of the DefaultView on the table where the text comes from. If
no text exists (that is, no...

Dear ASP.NET Programmers,
I have a question about a script I'm trying to code and invoke when a button
(btnSave) is pressed on the page. This script should only run when a textbox
(txtAD) on the page is left blank. I tried to use a code snippet with the
"return confirm" function but without success. The code should check whether
the textbox is empty or not, and if empty, it should ask the user to
continue and then run the next code. How...

Question - How can I write a If statement to see if a control (textbox)
actually exists on a page? Upon page_load, a certain control may or may not
be visible on the page so I need to first check to see if it actually exists
and then if it does, get the value from it. If I try to read it or check if
its "visible" if it's not on the page then of course, it'll error.
Thanks!

I have a form.
It has serveral text boxes for user data entry.
I could of course write code to check if each is empty before proceeding to
save this data to a file.
Is there any global way to control if any of these text boxes is empty or
are we really forced to do it on a one by one basis doing If....End is so
many times?

I am using vb.net 2005 and SQL server 2000. In my table I have a date field
of type "smalldatetime". In my vb application, the user may or may not enter
a date value into the appropriate text box. I then want to pass the value of
this text box as a datetime variable to my stored procedure which inserts or
updates the row.
As I mentioned above, the textbox may be left blank - hence I would want to
pass a null to the stored proc. How do I...

I have found articles on line about using word interop for spell checking
with visual studio applications.
Most of the articles are several years old, though - VS2003, maybe 2005. I
couldn't find anything for VS2008.
Are there any new improvements in spell checking with VS2008?
Thanks
Bill

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. 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...
