In traditional object-oriented languages, x = x + 1 is a simple and legal expression. But in Functional Programming, it's illegal. Variables don't exist in Functional Programming. Stored values are still called variables only because of history. In fact, they are constants. Once x takes a value, it...

A single line comment starts with two hyphens (--) and extends up to the end of the line. Example : -- This process models the state register process(clock, aresetn) begin if aresetn = '0' then -- Active low, asynchronous reset state <= IDLE; elsif rising_edge(clock) then --...

Starting with VHDL 2008, a comment can also extend on several lines. Multi-lines comments start with /* and end with */. Example : /* This process models the state register. It has an active low, asynchronous reset and is synchronized on the rising edge of the clock. */ process(clock, ...

These are the “bit fiddling” types. They have logical operators, too, such as xor, and they “wrap around” at the upper bound, to 0 again. type Bits is mod 2**24; L : Bits := 2#00001000_01010000_11001100# or 7;

A floating point type is characterised by its (decimal) digits which state the minimal precision requested. type Distance is digits 8; Earth : Distance := 40_075.017;

Decimal fixed point types are typically used in accounting. They are characterised by both a delta and a number of decimal digits. Their arithmetical operations reflect the rules of accounting. type Money is delta 0.001 digits 10; Oil_Price : Money := 56.402; Loss : Money := 0.002 / 3; -- ...

If you're accepting user input for folder paths, you might need to check for trailing backslashes (\) before building a file path. The FSO.BuildPath method makes this simpler: Const sourceFilePath As String = "C:\Temp" '<-- Without trailing backslash Const targetFilePath As Strin...

In this example you will explore how to export the following data from Acumatica ERP in a single call via the REST Contract-Based API: all stock items existing in the application all sales order of the IN type If you need to export records from Acumatica ERP, use the following URL: http://&l...

In this example you will explore how to export the following data from Acumatica ERP in batches via the REST Contract-Based API: stock items existing in the application in batches of 10 records all sales orders in batches of 100 records To export stock items in batches of 10 records with mult...

If you add controls from third party libraries in a C# WPF project, the XAML file will normally have lines like this one. xmlns:xctk="http://schemas.xceed.com/wpf/xaml/toolkit" This will perhaps not work with FsXaml. The designer and the compiler accepts that line, but there will prob...

Let's assume you have a ListView wich is supposed to display every User object listed under the Users Property of the ViewModel where Properties of the User object can get updated programatically. <ListView ItemsSource="{Binding Path=Users}" > <ListView.ItemTemplate> ...

This example implements a linked list with many of the same methods as that of the built-in list object. class Node: def __init__(self, val): self.data = val self.next = None def getData(self): return self.data def getNext(self): return self.ne...

Once using is used to introduce the name cout from the namespace std into the scope of the main function, the std::cout object can be referred to as cout alone. #include <iostream> int main() { using std::cout; cout << "Hello, world!\n"; }

If a using-declaration occurs at class scope, it is only allowed to redeclare a member of a base class. For example, using std::cout is not allowed at class scope. Often, the name redeclared is one that would otherwise be hidden. For example, in the below code, d1.foo only refers to Derived1::foo(c...
