VB.NET Tutorial 35 - Arrays (Visual Basic 2008/2010)

[Thomaxonal]

Obviously, someone being awake for more than 24 hours (at least..) then making an informative and instructional video for anyone to view at anytime and for free isn't quite good enough for 2 people.

[Thomaxonal]

Hey, does the For Next loop automatically increment by one per loop because you're specifying it to go from 0 to the length of the array?

Would there be a way to make it increment by 2 or a number other than one? In particular if the array was bigger than 5 elements long!

[SuaveProspect]

I know VB has capability of 2 DIMensional arrays, possible 3 Dim (like a cube).

Is there any app or idea for 4 or 5 Dim Arrays?

[SuaveProspect]

To cybersphere:

You would have to create many "Group Boxes" your "Project" would be huge, you screen uncontrollable, have to reset all variables....so on and so forth. Are you that lazy?

i am trying to Design and implement a program to store details about members in the fitness club, i am a beginner if anybody knows how to help please inbox me

[Samox70]

how pro you can also do

Msgbox

msgbox

msgbox..

I dont see a difference lmfao..

[xXNdeUrfeXx]

how do you use a loop to load the data into the array (using InputBox function) and another loop to output it to a listbox?

[Stevoid1990]

@xXNdeUrfeXx

From experience from other languages i'd imagine something like

arrayname = arrayname + string

[MsJunior511]

español please ..!

[cybersphere]

Rather than creating a new project for each new concept I'm exploring, I prefer to have one test project with a general module containing functions exploring different programming themes. I can then call these functions from the immediate window.This means I don't even have to leave design mode.

[acerjojo12]

I love your ascent dude...

[sopi351]

your voice not clear bro...

[owoxon]

@sopi351 your just deaf

[sopi351]

@owoxon u better learn English firstly and do the tutorials.u sounds like a ponzi

[FactoryModz]

@sopi351 shut the fuck up and get back in your hole before your uncle gets home.

[john55223]

How would you make it search for certain arrays, and edit those arrays, of different programs

[david2020able]

Thank You for the tutorials ,can you please do tutorial about shared memory in vb 2010,

like store a string in the memory and call this string usening another aplication

you cool thanks

I want to use the timer to call an array to change a label text. I don't know what to type for the timer. Does it need to be and if statement with Timer.Interval = 1000? Or what?

Anyone?

[chrisxbox3]

@ckd04 Here mate what you do is declare the time as a integer outside the events eg dim tmr as integer Next what you do is set tmr = 0 in the form load. Now open up a Event Click for what ever you called your timer. Inside that event put tmr = tmr + 1 Now everytime your time interval hits 1000 tmr will go up by 1, So put a if statement inside tht event If tmr = 1 then lblExample.show ElseIf trm = 2 lblExample2.show ElseIf trm = 3 Application.Exit And so on That is at least the timer part

[MrVBMagic]

Lol at first I thought that this was a tutorial for making 35 arrays. :P

Great tutorial by the way.

[Kingruler21]

What arrays can be useful for?i don t understand.

[Lacihun1]

@Kingruler21

Storing bunch of data, for example storing a list of number. Or store data from a .txt file (line by line)

[nathanm95]

i need to make a programme were a user types in some names and then the programme out puts the typed in names but in alphabetical order please help!!!

[fytr4lyf1]

@nathanm95

Array.Sort(arrayname)

[boxingcarracer]

is it same as

for i = 0 to i = 4

MessageBox.Show(tvshows(i))

i = i + 1

Next

[TheAgentbrady101]

@boxingcarracer Yes but in a for loop, you don't need to add the "i=i+1" part, that's the point in a for loop, unless you're trying to count by twos

[boxingcarracer]

@TheAgentbrady101 thank you sir. ..

[TheAgentbrady101]

@boxingcarracer Sounded sarcastic, wasn't being a smartass, just wanted to help...

[1111kalo]

thanks you

you very good

[lazicdusan9]

All is cartoons xD

[lazicdusan9]

@lazicdusan9 only supernatural is movie

[rb7brady]

@lazicdusan9 aha no

[ShadowDreadblade]

Well i suggest to add a mini add on tutorial on this, that shows two dimentional or even multi dimentional arrays. It would be useful for many students out there.

[ibenny100]

Great tutorial But you didn't really explain a real world case where arrays would be useful.

[kanchangupta19]

Very Nice....It helps me a lot...

[dominiquevaldes]

Can you make a sub that is byref so other subs can access a string of numbers. Everytime i try, it puts a squiggly under the number. Can anyone help?

[gala232]

Thanks!

[DrKillaser]

guys... if im an expert in one advanced programming language, and i want to learn another new language, will it be like learning a new language (such as English speaker learning German (same family)) or it would be more like learning the slangs of the same language (US english and GB English slangs are different, but the language is the same)

Notice the "if" condition.. xD.. im not an expert, yet.

[aintisaword]

When I do the for loop it just says family guy for all five.

[jetpaq]

Brilliant as usual,Thanks so much !

[Olemassacre]

Hey man. Can you set a time on arrays with out a timer?

[beckham7england4ever]

Thank you for this tutorial :D your channel is useful!!

[CrisIsRatedX]

Cant you just put

Dim tvshows() as string

So then it will hav unlimited values????

[Olemassacre]

@CrisIsRatedX Why would you do that? When you have all the values you want, count them and then enter the value in the array.

[Zolga00]

Lisp

[makoto114]

Do you have a tutorial for select case statements?

[liamick2006]

Does anyone know how to write a function in VB that returns the smallest value in an array of integers?? really annoying me

[elijahhezekiah1]

hey do you  think they make visual studios for mac??

[CrisIsRatedX]

@elijahhezekiah1 no because Visual Studios is a Microsoft program and Apple uses a different coding language that wont work with vs

[Lacihun1]

@elijahhezekiah1

Try Java instead of VB.NET it's platform independent. ;)

[mhkhattab]

can anyone help me with how to introduce a mathematical function to my form

[GriffinWiebel]

And all nighter? Why?

[kkorovesis]

sorry my mistake

[kkorovesis]

i dont know why but the programm need to declare the i first

so i Dim i as integer an the it works

[WhiteLightflame]

good video, but I needed to know something that wasn't covered. I have an array of objects (picture boxes) and I am trying to reference the array for collision detection on all of the picture boxes so that I don't have to go through all of them and state collision restrictions separately, how would I go about this?

[Makaveliz1]

thanxxxxxxxxxx

great lesson , u explained it better than the teacher at the uni. loooool

all the best.

[moustafa0122585186]

You were good,next time get some sleep :D

como meto un valor de un textbox a un arreglo

[hasnaeighrach]

thanks but i want to ask if there is another way to post up a table of number

and how we can let the users fill it

[chigozie123]

I am working on a number occurrences project. I need to be able to show how many times each number occurs in the array when a user types a bunch of numbers in, but now I am stuck on being able to show the amount of each number that the user types into the textbox. Help please!

[crazy13d2000]

Hi..

I need to know how can I pass data readed (using StreamReader) from a file to an array. I will be using that data to calculate the tax amount of a user. I have 2 arrays; 1 called strFields() to get each data readed, and another one called infoTax() to do the process of cal.

thank you.

[suupertramp]

i have an [Object reference not set to an instance of an object] problem

here is my code in the form: Dim testarray() As String Private Sub Button1_Click(etc) For i = 0 To 5 testarray(i) = "HELLO NUMBER " & i MessageBox.Show(testarray(i)) Next End Sub

and it throws the error at the top, why is that

[xtan1001]

why do you use "MessageBox.Show()" when you can just type "MsgBox()"

[motster246]

@xtan1001 for me it only works when i type MsgBox(), i dont know why

thank you so much, this video is a big help to me, because i am just a beginner, and i want to learn more, thanks for sharing

[upperkatt]

Can you make a memory game tutorial? I would love making such a game, that's one of my favorite games.

[esmatulah]

very helpful thanks

[twakskawt]

Hi there, first of all I want to say a BIG thank you for uploading your tutorials here in youtube. It's really a big help for a beginner like me. BTW, i just want to kindly ask if it is possible for an array to have two values? For example if i press Button2 twice, it will give me a value of "b" instead of "a". TIA

[ashleydooder]

First thanks for the VB.net help, very good!

Is there any material on how to add a textbox value to an array? I want to add 20 different words to a string array using a textbox for entry. Ive tried looping through but wont work......

Many thanks

[KHODAIE]

Write an Anagram Game that contains an array of 20 pre-set words. The game randomly selects a word and scrambles its letters. A Label displays the scrambled word for the user to guess. If the user guesses correctly, the game should display an indicator message as either a correct or a wrong answer. A new word would be selected if the guess is correct. Otherwise display a message and let the user try again up to 3 attempts.

[lullabynasdaq]

with less code:

Dim tvshows() as String = {"south park", "family guy", "american dad", "the simpsons", "supernatural"}

[sniperboy102]

you make a better a better professor than mine

[TheWorldswonder]

trying to manipulate images for a layout using an array but no matter how big the array defines only 2 images display.

Form has image defined pbNTaken. the idear is to create an array and copy this image into each element then display elemats as needed.

Problem is it only displays one image ( last image coppied into array.

Can you help?

[malachasmic]

@malachasmic I forgot to mention that the coding is located in a command button called btnSaveBooking

[bjvirk]

thanks for the video, how about parrallel arrays,

[marcky89869]

or maybe for a cooler way

dim random as new random

dim numbers as integer

dim array(19) as integer

dim i as integer

for i = 0 to array.length - 1

numbers = random.next(0,101)

array(i) = numbers

next

this will fill in random numbers between 0 and 100 till the last array index

[marcky89869]

hint: If you want to full and array with number without having to code the whole thing. look at this example.

dim array(20) as integer

dim i as integer

for i = 0 to array.length - 1

array(i) = i

next

this will fill in each array index the value of i ;) So you dont have to do it like so:

array(0) = 0

array(1) = 1

...etc
