Format datetime variable type

.NET Framework Developer's Guide

Custom DateTime Format Strings
You can exercise greater control over how a DateTime object is formatted by using custom DateTime format specifiers to create your own custom DateTime format string. Combine one or more custom format specifiers to construct a DateTime formatting pattern that yields the output you prefer. In fact, most of the standard DateTime format specifiers are aliases for formatting patterns specified in the currently applicable DateTimeFormatInfo Class.

My Example:

// PPI: I need to format date like this "01/12 - 12:05", but (/) was replaced
// with (-) so I invented an formula :D
dteCreditDate.ToString("dd_MM - hh:mm").Replace("_", "/")

ASCII Table references

ASCII stands for American Standard Code for Information Interchange. Computers can only understand numbers, so an ASCII code is the numerical representation of a character such as 'a' or '@' or an action of some sort. ASCII was developed a long time ago and now the non-printing characters are rarely used for their original purpose. Below is the ASCII character table and this includes descriptions of the first 32 non-printing characters. ASCII was actually designed for use with teletypes and so the descriptions are somewhat obscure. If someone says they want your CV however in ASCII format, all this means is they want 'plain' text with no formatting such as tabs, bold or underscoring - the raw format that any computer can understand. This is usually so they can easily import the file into their own applications without issues. Notepad.exe creates ASCII text, or in MS Word you can save a file as 'text only'

VB.NET Array usage

The following code shows how to declare an array in VB .NET. The value 10 gives the upper bound for the array. The lower bound is always 0 so this array contains 11 elements numbered 0 through 10.


Dim values(10) As Integer
As in VB 6, you can declare an array without bounds it. Later you can use ReDim to give it a size.
Dim values() As Integer
...
ReDim Preserve values(5)

Declare multi-dimensional arrays by separating the dimensions with commas.
Dim values1(9, 9) As Integer ' A 100 element array.
Dim values2(,) As Integer ' No bounds yet.
ReDim values2(9, 9) ' Give it bounds.

If you declare an array without bounds, you can initialize it during the declaration. Put the array items inside parentheses, separated with commas. The system automatically figures out what dimensions to use.

' An array with three values,
' indexes 0 through 2.
Dim values() As Integer = {1, 2, 3}

To initialize an array of objects, use the object constructors inside the value vector.
Dim primary_colors() As Pen = { _
New Pen(Color.Red), _
New Pen(Color.Green), _
New Pen(Color.Blue) _
}

For multi-dimensional arrays, put values for an array of one fewer dimensions inside more parentheses and separated by commas.
' A 2-D array with six values,
' indexes (0, 0) through (1, 2).
Dim values(,) As Integer = { _
{1, 2, 3}, _
{4, 5, 6}}

' A 3-D array with 12 values,
' indexes (0, 0, 0) through (1, 1, 2).
Dim values(,) As Integer = { _
{{1, 2, 3}, _
{4, 5, 6}}, _
{{7, 8, 9}, _
{10, 11, 12}} _
}
