Thanks Vania that looks much more like something I can convert to vb.  Appreciate your help.

Hi Nick,

....

private void btnSave_Click(object sender, RoutedEventArgs e)

{

var ms = new MemoryStream();

SaveFileDialog saveFileDialog =

new Microsoft.Win32.SaveFileDialog();

saveFileDialog.DefaultExt =

"png";

saveFileDialog.Filter =

"PNG Files (*.png)|*.png";

saveFileDialog.FilterIndex = 1;

if (saveFileDialog.ShowDialog() == true)

{

using (Stream stream = saveFileDialog.OpenFile())

{

StreamWriter sw = new StreamWriter(stream, System.Text.Encoding.UTF8);

sw.Write(ms.ToString().ToCharArray());

sw.Close();

stream.Close();

}

}

This code works fine in WPF.  I use it in my examples to save barcode image on the disc.

WriteableBitmap

There didn't seem to be a .Render or .InValidate when trying in a WPF App.

Found a workaround reference on the 'net saying as being available in Silverlight and not WPF.  The article said to use RenderTargetBitmap instead.

Then again my translation of that and the code from C# to vb.net could perhaps be a problem also.

Hi Nick,

I have not tested the code provided by Vania myself, however, I don't recognize anything about it that would indicate it being Silverlight-specific.  Have you been able to test it yourself and verify it working in a WPF application?

Thanks,

I think that probably works great in Silverlight what to do in just WPF?

Appreciate you help!
