VB.NET 2010 Embed Font

I'm trying to figure out how to embed a font into an application.  I don't want the font to be installed on the user's machine, but rather simply be used in a single control on the form.  I've tried numerous "embed font" code snippets only to run into errors with each one.

Any help appreciated.

That is precisely one of the code snippets I checked out that did nothing but produce errors.

This project is in C#.  I don't have any C# IDEs installed on my system.

I came up with a method on my own:

Imports System.Drawing.Text
Imports System.Runtime.InteropServices

Public Class FontResource
    Private PFC As PrivateFontCollection = Nothing

    Public Sub New(ByVal Res() As Byte)
        LoadFont(Res)
    End Sub

    Public ReadOnly Property GetInstance(ByVal Size As Single, ByVal style As FontStyle) As Font
        Get
            If PFC Is Nothing Then Return Nothing
            Return New Font(PFC.Families(0), Size, style)
        End Get
    End Property

    Public Function LoadFont(ByVal Res() As Byte) As Boolean
        Try
            PFC = New PrivateFontCollection
            Dim fontMemPointer As IntPtr = Marshal.AllocCoTaskMem(Res.Length)
            Marshal.Copy(My.Resources.VeraMono, 0, fontMemPointer, Res.Length)
            PFC.AddMemoryFont(fontMemPointer, Res.Length)
            Marshal.FreeCoTaskMem(fontMemPointer)
            Return True
        Catch ex As Exception
            Return False
        End Try
    End Function

End Class


Then call the resource by:

        Dim fnt As New FontResource(My.Resources.VeraMono)
        txtSQL.Font = fnt.GetInstance(8, FontStyle.Regular)


If anyone sees a problem with this method, please let me know.

Correction... While this method throws no errors, and does change the size of the text, it does not actually use the embedded font.  >:(

Grr.  As it turns out, Textboxes have no "UseCompatibleTextRendering" property.  Still looking for suggestions.
