Not using by means that the technology used is incidental, and the focus is on the approach being shown to be feasible. Without more context it's impossible to say what the intended import of the sentence is and whether by would actually be better or not. And that means that this question is Not A Real Question.
User kokos answered the wonderful Hidden Features of C# question by mentioning the using keyword. Can you elaborate on that? What are the uses of using?
By using a joystick or a pointing device, an on-screen keyboard allows people with mobility impairments to type data. The second sentence states that the on-screen keyboard is the one that uses the joystick or pointing device to allow impaired people to type data.
I have seen numerous sentences in which placement of the word "using" immediately following a noun causes just such ambiguity as in the first sentence. In some cases, introduction of extra verbiage such as "through the use of" or "by using" helps. In other cases, it is best to rewrite to avoid confusion and obtain a clearer, more concise sentence.
The Using scope modifier is supported in the following contexts: Remotely executed commands, started with Invoke-Command using the ComputerName, HostName, SSHConnection or Session parameters (remote session) Background jobs, started with Start-Job (out-of-process session) Thread jobs, started via Start-ThreadJob or ForEach-Object -Parallel ...
183 In C++11, the using keyword when used for type alias is identical to typedef. 7.1.3.2 A typedef-name can also be introduced by an alias-declaration. The identifier following the using keyword becomes a typedef-name and the optional attribute-specifier-seq following the identifier appertains to that typedef-name.
Yes Yes. Either way, when the using block is exited (either by successful completion or by error) it is closed. Although I think it would be better to organize like this because it's a lot easier to see what is going to happen, even for the new maintenance programmer who will support it later:
Updating the using keyword was specifically for templates, and (as was pointed out in the accepted answer) when you are working with non-templates using and typedef are mechanically identical, so the choice is totally up to the programmer on the grounds of readability and communication of intent.
With could work, but it sometimes connotes along with, as in with a companion, which is not the case. Using is the best bet, since that connotes using a tool, which is what we want. Also, do exploration is clunky, and sounds wrong. Explore means the same thing, but sounds much more natural: Explore using Mobile Robot.
