Save a Picturebox Image to a .bmp file in vb.net.  SavePicture is not available

I have a form that contains a picturebox that I've loaded up with an image and added the ability to freehand draw (Pen, Drawpath) in the picturebox.  I used to be able to leverage the SavePicture function to save that image to file but now am unable to find a solution in vb.net.

Thanks in advance.

try a function like:

Public Function saveImageByPic(ByVal pic As PictureBox, ByVal sNewFile As String, ByVal saveFormat As System.Drawing.Imaging.ImageFormat) As Boolean
        Dim bAns As Boolean
        Dim saveExt As String
        Try
            pic.Image.Save(sNewFile, saveFormat)
            bAns = True 'return true on success
        Catch
            bAns = False 'return false on error
        End Try
        Return bAns
    End Function

Thanks for the quick response.

Actually, I've already tried that.  It generates a file of an image before I painted on it.  I need it to generate a file that contains the image w/ the doodle.

Here's the snippet I used to doodle.
Private Sub pbtest_Paint((ByVal sender As Object, ByVal e As System.Windows.Forms.PaintEventArgs) Handles pbtest.Paint

Dim CurrentPen = New Pen(Color.FromArgb(myAlpha, strPencilColor), strPencilWidth) 'Set up the pen
            e.Graphics.DrawPath(CurrentPen, MousePath_EyeOutline)  'draw the path! :)

Any other ideas?

sorry, i should have clarified..

When i use the following, it saves a copy of the original image to the destination strFileName.  What I need is to save a copy of the image including my doodle.

pbtest.Image.Save(strFileName & ".jpg", System.Drawing.Imaging.ImageFormat.Jpeg)

You can try something like the below (VB2005) but I'm not sure if it's the best approach.


        Dim bmp As New Drawing.Bitmap(PictureBox1.Image.Width, PictureBox1.Image.Height)
        PictureBox1.DrawToBitmap(bmp, New Rectangle(0, 0, bmp.Width, bmp.Height))
        bmp.Save("c:\test.bmp")
