Color to hex

I'm not finding the correct syntax. This is what I have...

Code:

---

    Private Sub PictureBox1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles PictureBox1.Click
        If Pathstr <> "" Then
            Dim bitmap As New Bitmap(Pathstr)
            Dim LocalMousePosition As Point
            LocalMousePosition = PictureBox1.PointToClient(Cursor.Position)
            bgc = bitmap.GetPixel(LocalMousePosition.X, LocalMousePosition.Y)
            Label12.BackColor = bgc
        Else
            MsgBox("Please Drop an image before choosing color")
        End If
        ColorDialog1.Color = bgc
        ColorDialog1.FullOpen = True
        If ColorDialog1.ShowDialog <> Windows.Forms.DialogResult.Cancel Then
            Label12.BackColor = ColorDialog1.Color
        End If
        Dim intColor2Dec As Integer
        intColor2Dec = Convert.ToInt32(bgc)
        TextBox1.Text = Microsoft.VisualBasic.Conversion.Hex(intColor2Dec)
    End Sub

The Bold is where I am failing to convert to hex. What can I do to get this right?

Well, bgc is a color, which has a .ToARGB method, which returns an integer, that can be converted to a string with .ToString("X"), so it seems like all you'd need is:

TextBox1.Text = bgc.ToARGB.ToString("X")

I haven't tried it, though.

That was it. Thanks
