Redis provides three commands to count the items within a sorted set: ZCARD, ZCOUNT, ZLEXCOUNT.
The ZCARD command is the basic test for the cardinality of a set. (It is analogous to the SCARD command for sets.) . ZCARD returns the count of the members of a set.

If you do not only wish to display static objects, but have your UI respond to changes to correlating objects, you need to understand the basics of the INotifyPropertyChanged interface.
Assuming we have our MainWindowdefined as

As you may have noticed in the example above, we are rewriting the same step multiple times:
Given the user is on the login page
This can be exceptionally tedious, especially if we have more than one given step that is reused. Gherkin provides a solution for this by giving us another keyword to ...
In some cases you may want to rerun the same scenario over and over, substituting out the arguments. In this case, Gherkin provides several new keywords to accommodate this situation, Scenario Outline: and Example:. The Scenario Outline keyword tells Cucumber that the scenario is going to run multip...
Since Bootstrap 4 is a major rewrite, many of the Bootstrap 3.x class names have changed or been removed. The restructuring of components such as the Navbar, and the introduction of new CSS classes and Flexbox support means that upgrading to 4.x is not a simple conversion process from 3.x.
However,...

A character type is an enumeration that includes a character literal:
type Roman_Numeral is
('I', 'V', 'X', 'L', 'C', 'D', 'M', Unknown);`
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;
A fixed point type definition specifies a delta, and a range. Together, they describe how precisely real values should be approximated as they are represented by powers of two, not using floating point hardware.
Shoe_Ounce : constant := 2.54 / 64.0;
type Thickness is delta Shoe_Ounce range 0.00 .....
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...

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...
