Hi guys sory for being ooff grade 9 was a little ruf and yet gr 10 its still the same anyway>For my question
I ve got a picture box and in some size modes we all know you cant see everything so aamm then i fought about scrolling and i saw the crtl didnt have tht setting build in so amm ya if yuu guys could give me a example it would be gladly appreciated;)

What do you mean? what are you trying to say? Do u want the picture box to have a scroll? please clarify your complaint... thanks

I think he is wanting the picture to adjust to the size of the PictureBox. To do this, your code would look something like this:

Public Class Form1

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        'Sets the Title of the OpenFileDialog Box
        OpenFileDialog1.Title = "Choose Image to Open"
        'Sets the FileName(the Text in the TextBox of the OpenFileDialog Box)
        OpenFileDialog1.FileName = "Please Open an Image..."
        'Sets the Filter to 3 Types of images
        OpenFileDialog1.Filter = ".JPEG (.jpg)|*.jpg|.GIF (.gif)|*.gif|.PNG (.png)|*.png"
        'Shows the Dialog
        OpenFileDialog1.ShowDialog()
    End Sub

    Private Sub OpenFileDialog1_FileOk(ByVal sender As System.Object, ByVal e As System.ComponentModel.CancelEventArgs) Handles OpenFileDialog1.FileOk
        'Loads the Image into the PictureBox
        PictureBox1.Load(OpenFileDialog1.FileName)
        'Centers the Image
        Me.PictureBox1.SizeMode = PictureBoxSizeMode.CenterImage
        'Stretches it to fit the PictureBox
        PictureBox1.SizeMode = PictureBoxSizeMode.StretchImage
    End Sub

    Private Sub PictureBox1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles PictureBox1.Click
        'Opend the image in your default viewer
        Process.Start(OpenFileDialog1.FileName)
    End Sub
End Class

In this code, I made it where the OpenFileDialog opens when you start the application and then when you open the image, it will stretch and fit the PictureBox component. Also, I added it where when you click the image it opens up to the original size. You can view my notes for guidance if you would like.

If this is not what you are wanting to accomplish, then please continue to provide us with more information to assist you on you issue.

If you want a scrollable picturebox then do the following:

1. Add a panel to the form
2. Set the panel to the size you want the picturebox to be.
3. Set the panel's autoscroll = true
4. Set the panel's borderstyle = none
5. Add a picturebox to the panel.
6. Set the picturebox's location to 0,0
7. Set the picturebox's anchor to left or top, if not already
8. Set the picturebox's sizemode = autosize.
9. Set the panels borderstyle to the desired style.

When the picture is to big the picturebox will increase in size and the scrollbars will appear on the panel. You should handle the picturebox's MouseEnter event to set focus to the panel. That way the mouse wheel will scroll the picture up and down.

IM gona show code soon becuase there is a problem im currently Converting it from C# to vb2010 code

The problem here is tht he didnt include Image Location i would really like too know why
it doesnt have it in:?: and maybe if i can put this property back:idea:

You can add the property back by simply adding another property named ImageLocation. Look at the other properties.


You can also do the steps I provided and add this to your form. It should do the same thing as that.

Private Sub PictureBox1_MouseEnter(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles PictureBox1.MouseEnter
        Panel1.Focus()
    End Sub

    Private Sub PictureBox1_SizeModeChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles PictureBox1.SizeModeChanged

        Select Case PictureBox1.SizeMode

            Case PictureBoxSizeMode.AutoSize, PictureBoxSizeMode.Normal
                'Make scrollable
                PictureBox1.SizeMode = PictureBoxSizeMode.AutoSize
                Panel1.AutoScroll = True
                PictureBox1.Dock = DockStyle.None

            Case Else
                'if strecth then strech it. otherwise center it with the
                'same aspect ratio
                If PictureBox1.SizeMode <> PictureBoxSizeMode.StretchImage Then
                    PictureBox1.SizeMode = PictureBoxSizeMode.Zoom
                End If

                Panel1.AutoScroll = False
                PictureBox1.Dock = DockStyle.Fill

        End Select

    End Sub

Do you mean how to make it where it opens in a larger window when you click it and you can make it minimize back into its original size?
