I'm using the ink picture control and I'm having trouble getting my code to work.  I think I'm on the right track but I just cant figure it out.  Please help me I've been stuck on this for days. Thanks in advance  :)
Dim inkBounds As Rectangle
 
        With inkBounds
 
            .X = 0
 
            .Y = 0
 
            .Width = InkPicture1.Width
 
            .Height = InkPicture1.Height
 
        End With
 
        Dim img As Image
 
 
        img.Save(IO.Directory.GetCurrentDirectory() & "\test_out.jpg", System.Drawing.Imaging.ImageFormat.Jpeg)

I dont know what you are trying to do but the following lines would definitely produce error
Dim img As Image
img.Save(IO.Directory.GetCurrentDirectory() & "\test_out.jpg", System.Drawing.Imaging.ImageFormat.Jpeg)

And the error would be "Object reference not set to an instance of an object".

Please explain what you are trying to do.

I'm using the ink picture control, something you would use on a tablet pc.  Basically all i want to do is save the contents of the ink picture to a jpeg.

Do this
InkPicture1.Image.Save(IO.Directory.GetCurrentDirectory() & "\test_out.jpg", System.Drawing.Imaging.ImageFormat.Jpeg)

Okay I tried the line of code that you provided but still not having any luck.  Ive downloaded the tutorial, but the problem is he saves it as  a rtf file and not a jpeg.  Doing that only allows you to view the picture inside the program.

InkPicture1.Image.Save("C:\test_out.jpg", System.Drawing.Imaging.ImageFormat.Jpeg)

I keep getting an object reference not set to an instance of an object exception.  Do you think the rest of the code is right?

From the code you have given above in the question, DELETE EVERYTHING. You do not need any of that.

Just use this like and make sure the name of the control is correct and it exists.

If Not Isnothing(InkPicture1.Image) Then
   InkPicture1.Image.Save("C:\test_out.jpg", System.Drawing.Imaging.ImageFormat.Jpeg)
Else
   Messagebox.show ("No image!")
End If

The above code would probably show you the messagebox, then try the following link

It just keeps giving me exceptions.  The name of the control is correct and everything should work.  I'm wondering since its a windows xp tablet software control, if its vista that's screwing up

Lol sorry i still need a little help.  I dragged and dropped a savefiledialog on my form and converted the C# code this far:
Dim r As New Renderer
        Dim b2 As Bitmap
        Dim g1 As Graphics
 
 
 
 
 
 
 
 
        If SaveFileDialog1.ShowDialog = Windows.Forms.DialogResult.OK Then
 
 
 
            r.Draw(g1, InkPicture1.Ink.Strokes)
 
 
        End If
 
 
 
 
    End Sub
