Knowledge of Dim

[Ugleh]

For all the coding language I know, Variables is a must. It helps everything go smoothly, and thats what Dims are in Vb.Net, it represents Variables.

Now their are different types of Dims, and I will explain them all.
Now the basic dim is the string

Dim Var1 as String
Var1 = "Hello"

Or

Dim Var1 as String = "Hello"

You can also dim the sting using a textbox like

Dim Var1 as String
Var1 = Textbox1.text

Now you might think its not that useful but it is, lets take this for example. We want to put the Date in a message box, you cant just put

        MsgBox(DateTime = Today())

You will get an error, so what you do is this

        Dim TodayDate As DateTime = Today()
        MsgBox(TodayDate)

Giving it no error.

Now we have strings down, and custom Values, lets get to the rest.

Boolean
Boolean is a value of only True or False, an example would be

Dim a As Boolean = True

String
String is just words, a sentence, or a phrase. An example is above and below.

Dim Sti as String
Sti = "Hello There world!"

Byte
a Byte is an 8 bit unsigned integer, meaning its a data value, and a number.

Dim fileData As Byte

Char
Char is a variable type. It can hold one character at a time (the Char is short for Character).

Dim OneCharacter As Char
OneCharacter = "A"

DateTime
DateTime is also a Var type, this one you can go here for all the unique types.

Dim TodayDate As DateTime = DateTime.Now
        MsgBox(TodayDate)

Decimal
Decimals is numbers that aren't full, like 3.24. If you where to use a string for 3.24 it would just read it as 3, and not the full decimal.

Dim Dec as Decimal
Dec = 3.24

Dim myVar as <data type goes here>

There are afew more but these are the most commonly used. Hope you get the knowledge of Dims now.

I couldn't explain it better myself.
