    Picturebox Array (VB Express)

    Hi there,

    Is it possible to create an array of picturebox controls during
    run-time. I wish to create a new image/picturebox everytime a user
    clicks the button on a form, and they need to be objects so that the
    user can move/drag them around.


    The only examples I can find dont work as I am using VB Express (2005?)

    and the examples are writting in VB6.


    Is anyone able to help please?


    Toby.

      At class level in your form:

      Private m_pictureboxes As New ArrayList()

      In the Click event handler of your button:

      Dim _pic As New PictureBox

      _pic.Location = New System.Drawing. Point(<x>, <y>)

      _pic.Size = New System.Drawing. Size(<w>, <h>)

      ' set any other properties as required

      ' wire up the desired event handlers
      AddHandler _pic.<event>, AddressOf <event_handle r>

      Me.Controls.Add (_pic)

      m_pictureboxes. Add(_pic)

      where:

      <xand <yare the coordinates of the desired iniial position
      <wand <hare the width and height values for the desired size
      <eventis the desired event
      <event_handleri s the desired event hander (predefined)

      e.g.

      Private Sub PictureBox_Clic k(ByVal sender As System.Object, ByVal e As
      System.EventArg s)

      CType(sender, PictureBox).Bac kColor = Color.CadetBlue

      End Sub

      If you 'add' 3 pictureboxes by clicking the button three times and then
      click a picturebox, it's background colour will change.

      Obviously you will have to implement a mechanism for varying the <xand <y>
      values otherwise all the pictureboxes will be drawn in the same place.

          Toby,

          Instead of the label1 and label2 you can use pictureboxes

              Thanks very much for the responses, looks like I was almost there, but
              your examples have been a godsend! :-)

              Thanks again.

                  Toby.
                  Stepahnie,

                  How can I reference the image property of a picturebox in an array. I
                  would ahve assumed it was:

                  m_picturebox(1) .image

                  but that brings up errors. How can I change properties of these
                  controls in the array?

                  Thanks.
