For i = 0 To 12
pic = Me.Controls("picturebox" & i)
pic.Image = Image.FromFile("C:\Dev\Images\TEST400.jpg")

Help plz
Your image files should be saved as TEST1.jpg,TEST2.jpg, ......TEST12.jpg etc.
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim pic As PictureBox
For i = 1 To 12
pic = Me.Controls("picturebox" & i)
pic.Image = Image.FromFile(#"C:\Dev\Images\TEST" + i.ToString +".jpg")
Next i
End Sub
Note: I just wrote this code here only. Its not tested.

I tried doing it again erased it and it still didn't walk he was still running.
When I press the run it works ok. But when I press the walk it won't do the walk animation! Also when I start the program it starts running already. I want it to not run when the program is started I want it to run when I press the buttons.
The Run command starts Timer1. When Timer1 is done it starts Timer2. When Timer2 is done it goes back to Timer1. So run is just toggling back and forth between Timer1 and Timer2.
The Walk command starts Timer5, which starts Timer4 --> Timer3 --> Timer2 --> Timer1...and then gets stuck in the Run cycle toggling between Timer1 and Timer2.
What should the Walk sequence be?
If you don't want anything to be animating, then select each Timer and set the Enabled property to FALSE. Make sure you aren't turning any Timers on in the Load() event of your Form.
Try something like this out:
Public Class Form1
Private runSequence() As Image
Private walkSequence() As Image
Private runIndex As Integer = -1
Private walkIndex As Integer = -1
Private WithEvents trmRun As New System.Windows.Forms.Timer
Private WithEvents trmWalk As New System.Windows.Forms.Timer
Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
runSequence = {My.Resources.SONICRUN1_removebg_preview, My.Resources.SONICRUN2_removebg_preview,
My.Resources.SONICRUN3_removebg_preview, My.Resources.SONICRUN4_removebg_preview}
walkSequence = {My.Resources.SONICWALK1_removebg_preview, My.Resources.SONICWALK2_removebg_preview,
My.Resources.SONICWALK3_removebg_preview, My.Resources.SONICWALK4_removebg_preview,
My.Resources.SONICWALK5_removebg_preview, My.Resources.SONICWALK6_removebg_preview,
My.Resources.SONICWALK7_removebg_preview, My.Resources.SONICWALK8_removebg_preview}
trmRun.Interval = 100
trmRun.Enabled = False
trmWalk.Interval = 100
trmWalk.Enabled = False
End Sub
Private Sub btnRUN_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnRun.Click
trmWalk.Stop()
trmRun.Start()
End Sub
Private Sub btnWALK_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnWalk.Click
trmRun.Stop()
trmWalk.Start()
End Sub
Private Sub trmRun_Tick(sender As Object, e As EventArgs) Handles trmRun.Tick
runIndex = runIndex + 1
If runIndex = runSequence.Length Then
runIndex = 0
End If
PictureBox1.Image = runSequence(runIndex)
End Sub
Private Sub trmWalk_Tick(sender As Object, e As EventArgs) Handles trmWalk.Tick
walkIndex = walkIndex + 1
If walkIndex = walkSequence.Length Then
walkIndex = 0
End If
PictureBox1.Image = walkSequence(walkIndex)
End Sub
End Class
I really need some help with this dilemma.
I have two pictures of a light bulb. In one picture the light bulb is shining brightly and in the other it’s turned off. I’m supposed to overlap these pics and make it turn on and off by clicking on the image but I just can’t figure out the code for it. How do you toggle between these images? I am not allowed to use a button to do this. I've got to click on the pic to change it. Please help! Link below as I do not have enough rep to post actual images yet.

Firstly, i think that you should take a look here in order to understand the way images comparisson takes place. Secondly, the proper event to change the picture is the PictureBox.Click...
The code should be like the following one:
Public Class Form1
Dim imageBulbOff As Image = My.Resources.BulbOff
Dim imageBulbOn As Image = My.Resources.BulbOn
Private Sub Form1_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load
PictureBox1.Image = imageBulbOff
End Sub
Private Sub PictureBox1_Click(sender As System.Object, e As System.EventArgs) Handles PictureBox1.Click
If PictureBox1.Image Is imageBulbOff Then
PictureBox1.Image = imageBulbOn
Else
PictureBox1.Image = imageBulbOff
End If
End Sub
End Class
When I use an OpenFileDialog, and select a file and click open etc, etc...
I want a label on the same form to automatically update with the directory path. At the moment I have this working, However the label updates on click, not automatically on the directory change.
CODE:
Private Sub Label4_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Label4.Click
Label4.Text = OpenFileDialog2.FileName
End Sub
Cna I change the "Label4_Click" to something else for an auto update?
How are you displaying the OpenFileDialog? You need to update the Label from there!...
Something like:
Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
If OpenFileDialog2.ShowDialog = Windows.Forms.DialogResult.OK Then
Label4.Text = OpenFileDialog2.FileName
End If
End Sub
This code is throwing TwitterAPIException on this line
profilepic.ImageLocation = twitter.AccountInformation.ProfileImageUrl
I have a feeling it may be because it isn't authenticating but I'm not sure. any idea why i might be getting this, also how can i in my code check if twitter has authenticated me before trying to actually read data?
I have removed the private keys for privacy
Imports TwitterVB2
Public Class Form1
Dim twitter As New TwitterAPI
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
End Sub
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles verify_btn.Click
twitter.AuthenticateWith("", "", "", "")
profilepic.BackColor = Color.White
profilepic.ImageLocation = twitter.AccountInformation.ProfileImageUrl
tw_name.Text = "HI" + twitter.AccountInformation.Name
For Each Tweet As TwitterStatus In twitter.HomeTimeline
tweets.AppendText(vbNewLine + vbNewLine + Tweet.User.ScreenName + vbNewLine + Tweet.Text + vbNewLine + Tweet.CreatedAtLocalTime + vbNewLine + vbNewLine + "..............................")
Next
End Sub

I'm the developer of TwitterVB. :)
Because I stopped updating the library in 2011, TwitterVB was never updated to work with version 1.1 of the Twitter API. I've gotten many, many requests to address this specific issue, so I have made an updated version of the DLL available here:
https://github.com/DWRoelands/TwitterVB/releases/tag/3.1.1
Please note that I have done no testing and that this DLL should be considered "pre-release". If you have questions or issues, I'll do my best to answer them. You can reach me via my GitHub page:
https://github.com/DWRoelands
Trying to add event handlers to radio buttons that are created on user input, looking at this and this as examples.
However I get an error that answerOptions is not an event.
Create the radio buttons
Private answerOptions(n) As RadioButton
...
Private Sub showQuestion(n As Integer)
For i = 0 To answerOptions.Length - 1
answerOptions(i) = New RadioButton
AddHandler answerOptions, AddressOf Me.Radios_Click
With answerOptions(i)
' --------- SET TEXT, LOCATION ETC.
End With
Me.Controls.Add(answerOptions(i))
Next
End Sub
Planning on then handling events with
Private Sub Radios_Click(sender As Object, e As EventArgs) Handles answerOptions.checked
End Sub
I want things to happen when the radios are checked. Don't want to use checkboxes as I want to limit one selection at a time.
Try this in your form or page
Private Sub ClickButton(ByVal sender As System.Object, ByVal e As System.EventArgs)
Dim Rbtn As RadioButton
Rbtn = CType(sender, RadioButton)
MsgBox(Rbtn.Text)
End Sub
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim i As Integer
Dim Rbtn As New RadioButton()
For i = 0 To 19
Rbtn = New RadioButton()
With Rbtn
.Name = "RBtn" & i
.Text = .Name
.Checked = False
.Left = 20
.Top = (i * 20)
.Visible = True
Me.Controls.Add(Rbtn)
AddHandler Rbtn.Click, AddressOf ClickButton
End With
Next
End Sub
