Simple solution - Works with VB6 / Win7
You can create graphics using Paint. Just make the transparent section in the color
you chose to be transparent. In this example I am using color (&H000001&)
Any pixels of this color (almost black) will be transparent.
(note: you can use any color to be transparent)

   ' Copy this code to your VB6 form
   ' ================================
   Declare Function GetWindowLong& Lib "user32" Alias "GetWindowLongA" ( _
      ByVal hwnd&, ByVal nIndex&)
   Declare Function SetWindowLong& Lib "user32" Alias "SetWindowLongA" ( _
      ByVal hwnd&, ByVal nIndex&, ByVal dwNewLong&)
   Declare Function SetLayeredWindowAttributes& Lib "user32" ( _
      ByVal hwnd&, ByVal crKey&, ByVal bAlpha As Byte, ByVal dwFlags&)
   Public Const GwlStyle& = (-16)
   Public Const GwlExStyle& = (-20)
   Public Const WsExLayered& = &H80000
   Public Const LwaColorKey& = &H1
   Public Const LwaAlphaA& = &H2

   ' ================================
Sub Form_Load()
      SetWindowLong Me.hwnd, GWL_EXSTYLE, GetWindowLong(Me.hwnd, GWL_EXSTYLE) Or WS_EX_LAYERED
      SetLayeredWindowAttributes Me.hwnd, &H000001&, 0&, LWA_COLORKEY
      Me.BackColor = &H000001& ' Make background transparent
End Sub
   ' ================================

Maybe.

I was thinking there's some overlap here with the resizer control and the need for a more advanced control container/picturebox.

Wouldn't it make sense to have a single container control with optional scrollbars/resizing/borders (a la resizer) plus theming/background picture/jerry-rigged transparency (a la tabcontrolpage) and call it XtremeContainer?

If you want to use the CJ controls Transparent property, use the CJ control TabControlPage as the container for the control(s).

This works.

Control is truly transparent at runtime (not design time). See image below.
