Yes, Tim is correct. The Font property is not supported by the PictureBox
control.

Thank you,
Sergiy.

| The actual issue is with getting and setting the Font property. It looks
| like it's not supported for the PictureBox. If you create your own
property
| to store the font it should work. Add the code below to your PicBody
class.
|
| Private _Font As Font = New Font("Tahoma", 8, FontStyle.Regular)
|
| Public Overrides Property Font() As System.Drawing.Font
| Get
| Return _Font
| End Get
| Set(ByVal Value As System.Drawing.Font)
| _Font = Value
| End Set
| End Property
