This is a pretty straightforward query: allDevices.Where(d => d.Options.Any(o => o.Name == “Foot Pedal” && o.Installed)); Remember that a lambda is just a function. It can call other functions, declare variables, and everything else you can do in normal code. solved Linq and List of Lists
You missed px in css translate(0, npx) is correct, jQUery css({}) function won’t add default px when css property has multiple param this would be correct, if single param $(“<selector>”).css({‘height’: wHeight}) but translate() properly takes multiple params so you will need to add unit with value $(‘.test’).css({“-moz-transform”:”translate(0,” +wHeight+ “px)” }); solved jQuery translate value adding … Read more
You can do something like this: Pattern pat = Pattern.compile(“((?:[^\u0003]*\u0003){30}[^\u0003]*)\u0003(.*)”); Matcher matcher = pat.matcher(input); if (matcher.matches()) { String leftPart = matcher.group(1); String rightPart = matcher.group(2); } The pattern works as follows: The first capture group finds a substring with exactly 30 occurrences of the separator \u0003; the subpattern that finds a substring with no separators, … Read more

Abc &obj11 = fun1(); This line makes the program ill-formed; the C++ specification forbids temporaries to be bound to a reference that is not const. A compliant C++ compiler would emit an error to this effect. Presumably you are using the Microsoft Visual C++ compiler, which is well-known for allowing the binding of a temporary … Read more
this.name = other.name; I think that should work. Update: I forgot you want to swap their names, so: String aux = this.name; this.name = other.getName(); other.setName(aux); You will need a setName and getName methods since “name” is private. 5 solved How do you change the contents of an object in JAVA?

This is taking the pairs by value: void swap (pair a, pair b) // a is a copy of pairs[i] and b is a copy of pairs[j] The change you make to a and b inside the function will be discarded when the function exits. a and b are local to the function only. Take … Read more
JQuery is a JavaScript Library. It simplifies JavaScript programming. It is a lightweight. It takes a lot of common tasks that require many lines of JavaScript code to accomplish, and wraps them into methods that you can call with a single line of code. It also simplifies a lot of the complicated things from JavaScript, … Read more
To use Matcher you start by compiling a Pattern, then you call matcher(String) and then you see if it matches. Finally, you can parse the values. Something like, String str = “views: 120 upvotes: 540”; Pattern p = Pattern.compile(“views:\\s*(\\d+)\\s+upvotes:\\s*(\\d+)”, Pattern.CASE_INSENSITIVE); Matcher m = p.matcher(str); if (m.matches()) { int views = Integer.parseInt(m.group(1)); int upvotes = Integer.parseInt(m.group(2)); … Read more
You could do this easily in two ways: Pass a ‘print token’ between the threads using two semaphores: thread 1 prints, signals semaphore A, waits on semaphore B then loops. Thread 2 waits on semaphore A, prints, signals semaphore B and loops. Write in-line, single-threaded code. 1 solved How can I get my threaded program … Read more
Unless you have a global char*[] you want to return from this function, yes, you need dynamic allocation, it is the only way you can safely return a variable created inside the function, for all variables stored in the stack will be destroyed as soon as the function finishes. char** myfun() { char **p = … Read more
JLabel is a subclass of JContainer.
