PROGRAM zprogram. ... MESSAGE i050(sabapdemos). It may be inconvenient to define a message class for the entire program, so it is possible to define the message class that the message comes from in the MESSAGE statement itself. This example will display message 050 from the message class sabapd...

In cases where you need to ensure model validation using Jquery, .valid() function can be used. The model class fields [Required] [Display(Name = "Number of Hospitals")] public int Hospitals{ get; set; } [Required] [Display(Name = "Number of Beds")] public int Beds { get; ...

Most special characters can be escaped using the caret(^). Take a look at the following example. echo > Hi echo ^> Hi This first command would not output > Hi because > is a special character, which means redirect output to a file. In this case, the file is named "Hi" Ho...

From this website, the OP has noticed a problem. Cause Consider the following code snippet. if 1==1 ( set /a result = 2*(3+4) ) At your first glance, you may think CMD.exe would process it like so: The condition is true, execute code block Set variable result's value to 14 Continu...

When there's an expression with a pipe the cmd starts two threads on both sides of the pipe and the expression is parsed twice (for each side of the pipe) so carets need to be doubled. On the left side: echo ^^^&|more On the right side: break|echo ^^^&

Another heuristic commonly used instead of union by size is the union by rank heuristic Its basic idea is that we don't actually need to store the exact size of the sets, an approximation of the size (in this case: roughly the logarithm of the set's size) suffices to achieve the same speed as union...

While in combination with path compression, union by rank nearly achieves constant time operations on union-find data structures, there is a final trick that allows us to get rid of the rank storage altogether by storing the rank in out-of-bounds entries of the parentarray. It is based on the follow...

std::boolalpha and std::noboolalpha - switch between textual and numeric representation of booleans. std::cout << std::boolalpha << 1; // Output: true std::cout << std::noboolalpha << false; // Output: 0 bool boolValue; std::cin >> std::boolalpha >> bool...

std::ends - inserts a null character '\0' to output stream. More formally this manipulator's declaration looks like template <class charT, class traits> std::basic_ostream<charT, traits>& ends(std::basic_ostream<charT, traits>& os); and this manipulator places charact...

std::ws - consumes leading whitespaces in input stream. It different from std::skipws. #include <sstream> ... std::string str; std::istringstream(" \v\n\r\t Wow!There is no whitespaces!") >> std::ws >> str; std::cout << str; // Output: Wow!There is n...

Detailed instructions on getting wsdl set up or installed.

As the powershell is installed by default on every windows system from 7/2008 and above it can be used for more complex calculations: @echo off set "expression=(2+3)*10/1000" for /f %%# in ('"powershell %expression%"') do set result=%%# echo %result% Mind the additional do...

WSH/JScript is installed on every windows system since NT so using it for more complex calculations makes it pretty portable. JScript is easier for combining it with batch file : @if (@codesection==@batch) @then @echo off set "expression=2*(2+3)/1000" for /f %%# in ('cscript //nologo...

Here can be found the most comprehensive math library that emulates pen and paper calculations and allows working with bigger numbers. Here are another examples of pen and paper emulations: ADD , Comparison , Multiply Some math functions implementations can be found here.

Arrow function is the new way of defining a function in ECMAScript 6. // traditional way of declaring and defining function var sum = function(a,b) { return a+b; } // Arrow Function let sum = (a, b)=> a+b; //Function defination using multiple lines let checkIfEven = (a) => { ...

this in function refers to instance object used to call that function but this in arrow function is equal to this of function in which arrow function is defined. Let's understand using diagram Understanding using examples. var normalFn = function(){ console.log(this) // refers to global/windo...
