and this is my code on form2....
what i need is, when i clicked the btnRed on form1, on form2 only the PnlRed show..
when the BtnGreen is clicked, Pnlgreen on form2..
my problem is both panel colors show when i click only one button.. what should i do? can someone help me please.
Add a Form level variable to frmChanger with its datatype as Color and its scope as Friend (so it can be seen from frmColor). This code is using the default instance of the form. You don't really need a separate form for each color. You only want to have a different color shown. How about a single panel that will have different colors instead of multiple panels.
In the Form1 code (your frmColor)
Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
Form2.panelColor = Color.Red
Form2.Show()
End Sub
Repeat for the other buttons with = Color.Green etc.
In Form2 (your frmChanger)
Friend panelColor As Color
Private Sub Form2_Load(sender As Object, e As EventArgs) Handles MyBase.Load
Panel1.BackColor = panelColor
End Sub

i have a baseform and a few forms inherited from that.
Call them BaseForm and Form1, Form2
I want to select a color in Form1 and these color is set in all inherited forms.
That works, if the form is open after the color is changed.
Let me explain.
I open Form1
select the color and set a global variable(glColorVariable).
The Backgroundcolor in the Baseform.Designer.vb is set
me.backcolor=glColorVariable
The color in Form1 didn't change
If i now open form2 the color in form2 IS changed.
How can i ... repaint my Baseform in Form1 so the color is changed.
Thank you verry much!

You can't loop forms so that you can change a parameter on them.
I think the Assembly.GetExecutingAssembly().GetTypes() is dead end for this.
One solution, if you fill an list element with your forms.
Dim Forms As New List(Of Form)
Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
Forms.Add(My.Forms.Form1)
Forms.Add(My.Forms.Form2)
Forms.Add(My.Forms.Form3)
End Sub
Sub SetBackColors(ByVal c As Color)
For Each f In Forms
f.BackColor = c
Next
End Sub
Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
SetBackColors(Color.Red)
End Sub
Private Sub Button2_Click(sender As Object, e As EventArgs) Handles Button2.Click
Form2.Show()
Form3.Show()
End Sub
or what Jimi wrote, use DataBindings:
Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
Form2.DataBindings.Add("BackColor", Me, "BackColor", False, DataSourceUpdateMode.OnPropertyChanged)
Form3.DataBindings.Add("BackColor", Me, "BackColor", False, DataSourceUpdateMode.OnPropertyChanged)
End Sub
Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
Me.BackColor = Color.Red
End Sub
Private Sub Button2_Click(sender As Object, e As EventArgs) Handles Button2.Click
Form2.Show()
Form3.Show()
End Sub
I'm writing a VB program that has multiple positions where when the user hovers over an item, the same image appears.
Currently I have:
Private Sub PictureBox1_MouseMove(sender As Object, e As MouseEventArgs) Handles PictureBox1.MouseMove
PictureBox1.Image = Image.FromFile(picturePath)
End Sub
Private Sub PictureBox2_MouseMove(sender As Object, e As MouseEventArgs) Handles PictureBox2.MouseMove
PictureBox2.Image = Image.FromFile(picturePath)
End Sub
Private Sub PictureBox3_MouseMove(sender As Object, e As MouseEventArgs) Handles PictureBox3.MouseMove
PictureBox3.Image = Image.FromFile(picturePath)
End Sub
Private Sub PictureBox4_MouseMove(sender As Object, e As MouseEventArgs) Handles PictureBox4.MouseMove
PictureBox4.Image = Image.FromFile(picturePath)
End Sub
Private Sub PictureBox5_MouseMove(sender As Object, e As MouseEventArgs) Handles PictureBox5.MouseMove
PictureBox5.Image = Image.FromFile(picturePath)
End Sub
Private Sub PictureBox6_MouseMove(sender As Object, e As MouseEventArgs) Handles PictureBox6.MouseMove
PictureBox6.Image = Image.FromFile(picturePath)
End Sub
Private Sub PictureBox7_MouseMove(sender As Object, e As MouseEventArgs) Handles PictureBox7.MouseMove
PictureBox7.Image = Image.FromFile(picturePath)
End Sub
This works fine, however, I am looking to condense my code. Surely there is a way of making this into just 1 or 2 private subs.
Note that this is just a snippet of my code.
The names of the objects are easily named PictureBox1, PictureBox2 etc.
Regards
Hugo.
Private Sub PictureBox_MouseMove(sender As Object, e As MouseEventArgs) Handles PictureBox1.MouseMove, PictureBox2.MouseMove, PictureBox3.MouseMove, PictureBox4.MouseMove, PictureBox5.MouseMove, PictureBox6.MouseMove, PictureBox7.MouseMove
DirectCast(sender, PictureBox).Image = Image.FromFile(picturePath)
End Sub
So i have a form as below:
Public Class IPADSOFT
Private Sub Button6_Click(sender As Object, e As EventArgs) Handles Button6.Click
IPADSOFTTS.Show()
End Sub
Private Sub Button8_Click(sender As Object, e As EventArgs) Handles Button8.Click
Me.Hide()
End Sub
Private Sub Button7_Click(sender As Object, e As EventArgs) Handles Button7.Click
HOME.Show()
Me.Hide()
End Sub
End Class
which has 3 checkboxes labeled IPADSOFTBOX1, IPADSOFTBOX2, IPADSOFTBOX3
So... i have another form as follows:
Public Class IPADSOFTTS
Private Sub onload()
If IPADSOFT.IPADSOFTBOX1.Checked Then
Button1.Visible = True
Button3.Visible = True
Button5.Visible = True
End If
End Sub
Private Sub Button8_Click(sender As Object, e As EventArgs) Handles Button8.Click
Me.Hide()
End Sub
Private Sub Button2_Click(sender As Object, e As EventArgs) Handles Button2.Click
End Sub
Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
End Sub
Private Sub Button7_Click(sender As Object, e As EventArgs) Handles Button7.Click
HOME.Show()
IPADSOFT.Hide()
Me.Hide()
End Sub
End Class
Now the idea is that all the buttons on that second form are set to visible-false and i want the page to check which checkboxes are checked on the last form and then make the required buttons on this form visible... but it isnt working
What am i doing wrong?? i apologise im very very new to vb.net
Open the second form with this
Dim newForm As New IPADSOFTTS With
{.MainForm = Me}
newForm .Show()
Set Public MainForm As IPADSOFT below the Public Class of second form
Then use in the Load event
if MainForm.IPADSOFTBOX1.Checked = true then
'Do whatever
End if
i am getting really annoyed by this piece of code for visual basic
please can you help. i have looked on YouTube and everywhere else even the vb website!!! i would really appreciate it if someone could help me out

BTW:this is my first post so it is probably rubbish!!
I don't have enough points to comment.
First off, as others have said we can't recreate this since we have no idea what your Form looks like or what you are expecting it to do.
Secondly, you should turn on Option Strict in the Compile section of Project properties to avoid technical errors like ProgressBar2.Increment(0.6) since 0.6 isn't a valid integer.
I threw together a TabControl (which you never mentioned in the OP) with 3 tabs and the various buttons and progress bars you list in what seemed like a logical fashion to me and it ran just fine for what code you have. Clicked the button on each tab and each progress bar eventually got to 100%. I have no idea what else you were expecting.
If you remove all the empty subs and action listeners, it would be easier to detect the problem
i have two RadioButtons one for Light Blue and the other for Ghost White and a button to show the next Form (Form2)
i want to be able to check on a Radio Button and the backcolor of form2 changes to the checked Radio Button
this is what i have on my coding so far
Private Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
SecondForm.Show()
End Sub
Private Sub rbLightBlue_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles rbLightBlue.CheckedChanged
If rbLightBlue.Checked Then
SecondForm.BackColor = (Color.LightBlue)
End If
End Sub
Private Sub rbGhostWhite_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles rbGhostWhite.CheckedChanged
If rbGhostWhite.Checked Then
SecondForm.BackColor = (Color.GhostWhite)
End If
End Sub
The problem am having is making the background color change on Form2.
Any answer for this question will be very helpful.
I am not sure what you are doing, it probably has to do with how you are creating your SecondForm, this code does work, see if it helps you narrow it down.
Public Class Form1
Dim SecondForm As Form2 = New Form2
Private Sub rbLightBlue_CheckedChanged(sender As Object, e As EventArgs) Handles rbLightBlue.CheckedChanged
If DirectCast(sender, RadioButton).Checked Then
SecondForm.BackColor = Color.LightBlue
End If
End Sub
Private Sub rbGhostWhite_CheckedChanged(sender As Object, e As EventArgs) Handles rbGhostWhite.CheckedChanged
If DirectCast(sender, RadioButton).Checked Then
SecondForm.BackColor = Color.GhostWhite
End If
End Sub
Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
SecondForm.Show()
End Sub
End Class
