Returns the expression as an array. @(Get-ChildItem $env:windir\System32\ntdll.dll) Will return an array with one item @(Get-ChildItem $env:windir\System32) Will return an array with all the items in the folder (which is not a change of behavior from the inner expression.

A very common use-case in web applications is performing multiple asynchronous (eg. HTTP) requests and gathering their results as they arrive or all of them at once (eg. in Angular2 with the HTTP service). 1. Gathering async responses one by one as they arrive This is typically done with mergeMap(...

To run ARM assembly code you will need a machine with an ARM processor. If you are on Linux you can use the following commands to compile your program: as -o prog_object.o my_prog_source.s Link to get the executable: ld -o run_prog prog_object.o Run using: ./run_prog If you run echo $? it wil...

In kafka, each consumer from the same consumer group gets assigned one or more partitions. Note that it is not possible for two consumers to consume from the same partition. The number of flink consumers depends on the flink parallelism (defaults to 1). There are three possible cases: kafka pa...

There are several ways to search a given value in std::set or in std::multiset: To get the iterator of the first occurrence of a key, the find() function can be used. It returns end() if the key does not exist. std::set<int> sut; sut.insert(10); sut.insert(15); sut.insert(22); ...

This iteration changes a value from a starting point to an end, optionally by a specified value for each step. The default change is 1. DEFINE VARIABLE i AS INTEGER NO-UNDO. DO i = 10 TO 15: DISPLAY i WITH FRAME x1 6 DOWN . DOWN WITH FRAME x1. END. Result: ---------------i ...

Dictionaries can be constructed by passing it any number of pairs. julia> Dict("A"=>1, "B"=>2) Dict{String,Int64} with 2 entries: "B" => 2 "A" => 1 You can get entries in a dictionary putting the key in square brackets. julia> dic...

Converting date and time strings to numeric arrays can be done with datenum, though it may take as much as half the time of reading a large data file. Consider the data in example Textscan. By, again, using textscan and interpret date and time as integers, they can rapidly be converted into a numer...

The LineChart class presents the data as a series of data points connected with straight lines. Each data point is wrapped in XYChart.Data object, and the data points are grouped in XYChart.Series. Each XYChart.Data object has two fields, which can be accessed using getXValue and getYValue, that co...

Consider you have a Parent Frame(Frame-Parent). and 2 child frames(Frame_Son,Frame_Daughter). Lets see various conditions and how to handle. 1.From Parent to Son or Daughter: driver.switchTo().frame("Frame_Son"); driver.switchTo().frame("Frame_Daughter"); 2.From Son to Pa...
