asp.net runs in a browser, and is not part of the operating system. You need to run in the OS to talk to Serial ports. That's why you can't find anything.

This is the asp.net discussion.
If you want to communicate with serial ports or usb ports, to need to write a windows, mac or linux application, which is a different discussion and topic altogether.
The old versions of vb had a modem control, that will open a port for transmitting and receiving, but that was back in 1998, over 14 years ago.
Modern day programs that do that are written in c++, and sample code for that would not be enough to get you started.

For an existing C# 2010 web form application, I developed a few new pages for the site last year. My code is separate from the production web site. I now want to add my code to the production code.
In the application I have 2 new web pages and one dbml file. (linq to sql).
Do you have recommendations on how to add this code to the production website. I want to wamke certain everything is 'wired' together correctly. How would you suggest I add my 2 new web pages with the least amount of recoding required?

Well if the files are separate ( new files with unique names ), you should be able to just drop them in and run a test to make sure they work. Then you'll probably have to make some menu changes.
If your replacing files, rename the extensions to old or something, add your new files, and run your test. if all is good, delete the old files.
If your unsure of your code, or just really cautious, then do it early Sunday morning or late Sunday night, sometime when traffic is low.

Where will your data come from? How will you match it to the first column?
You could populate the stored procedure according to your needs with a column containing the appropriate data from within the database (where data should be handled) and then bind that to the grid.

It would be better to use datalist to do that. DataList is actually made to handle such scenarios.
Set the datalist Datasource to the datatable containing this data. Set the repeatdirection=vertical. repeatlayout=table and repeatcolumns=2. Thats it you have what you want.

Better option is to use of Datalist..Datalist fullfills your requirement without any efforts.

What does this mean? If you have a question then please edit the above post and enter the details. If you want to know what interview questions you are likely to be asked for some job, then try a Google search, there are lots of different ones around.

It depends on individuals who is taking the interview and who is giving it.
Their ability, knowledge-base, need/requirement for the position, etc drives it.
It's suggestible that you prepare what you have done in last 2 years and go ahead. One need to be a little hands on to be strong on a given area.
Still, if you feel like going through questions, Google for it OR look for similar questions asked earlier here: CP Search result[^]
