Referencing Controls created at run time.

Hi all. I've found a small bit of code that allows me to create a bunch of
picture boxes at run time, but I still need an example of how to handle the
controls in code. I need to access the mouse events for each individual
picture and place graphics and text in the boxes. Can anyone help?

Add an event handlerfor each event you want to handle using AddHandler.
Note
that you are naming all of your picture boxes the same name in your loop.

I want to create a new picture box for every record in a database table,

run time.

need, I also don't know how many handlers I will need.

Hello

small example:

Public Class Form1
>
Dim pictures() As PictureBox
Const NO_OF_PICTURES As Int32 = 15
>
>
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As

ReDim pictures(NO_OF_PICTURES - 1)
For picture As Int32 = 0 To NO_OF_PICTURES - 1
pictures(picture) = New PictureBox
With pictures(picture)
.BackColor = Color.Red
.Width = 30
.Height = 30
.Top = 50
.Left = picture * 35 + 10
.Visible = True
.Tag = picture.ToString
AddHandler .Click, AddressOf Picture_Click
End With
Me.Controls.Add(pictures(picture))
Next picture
>
End Sub

>
Private Sub Picture_Click(ByVal sender As System.Object, ByVal e As
System.EventArgs)

Dim picture As PictureBox = CType(sender, PictureBox)

MsgBox("Picture " & picture.Tag.ToString & " clicked")
>
End Sub
>
>
>
Private Sub Form1_FormClosed(ByVal sender As Object, ByVal e As
System.Windows.Forms.FormClosedEventArgs) Handles Me.FormClosed

If pictures IsNot Nothing Then
For picture As Int32 = 0 To NO_OF_PICTURES - 1
With pictures(picture)
RemoveHandler .Click, AddressOf Picture_Click
End With
Next picture
End If
>
End Sub
>
End Class

In Button1_Click die picture boxes are created and a handler is adder
(allways to the same sub!).
In Picture_Click the parameter sender says, which picture box is clicked.
If reffered them by the tag property.
Finally in Form1_FormClosed all handlers are removed again - I think this
should be done if you load new data.
