I have built a control that runs an on-line help system. Depending on the
category you selected via dropdownlist, it goes out and gets the child
subcategories, and if there are any, adds a new dropdownlist to the screen
for selection. This continues until there are no children, and then it
checks for a help article list based on that last selection and displays
actual articles for display.
Adding the controls and getting everything...

Trying to figure out the technique which should be used
to add rows to a datagrid. I am thinking that I would
want an "Add" button on the footer, but I am not quite
sure how to do that. Is that the best method? Do you
have a sample of how to do this?

Hello
I wrote a program with code behind in C# to add row into table
dynamically and the program worked very well in .Net Framework 1.1. When I
run this program in .Net Framework 2.0 beta version, the program is not
working as in version 1.1. So what is the problem? Microsoft declared that
the version 2.0 is fully backward support, but it is not. Is that the
problem with 2.0 version?
I find out the problem in version 2.0. After...

where pc.category_id = $category_id

Hi
I have this table which I create on runtime with some rows from my
database.
What I want to do is when I create the table I want to create a button/
linkbutton/link or something beside each entry from the database and
when the user clicks on this button i want to remove the database
entry from the table.
So I guess my question is, how do I create a button with an onClick
event on runtime that knows what row it belong to.. So i can...

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,...

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.
