Hello,
I have an application where I want to load new DocumentWindows when doubleclicking a PDF file. The DocumentWindow contains a WebBrowser control that should load AdobeReader and show the PDF file.

Today I have one DocumentWindow with a WebBrowser control that updates when I change PDF file, but now when I want to open more windows I got this error:

The runtime has encountered a fatal error. The address of the error was at 0x657aa70d, on thread 0x2450. The error code is 0x80131623. This error may be a bug in the CLR or in the unsafe or non-verifiable portions of user code. Common sources of this bug include user marshaling errors for COM-interop or PInvoke, which may corrupt the stack.

The DocumentWindow is created and added to the Workspace but the error occur when I try selecting the new tab (DocumentWindow). I have tried comment out the WebBrowser code and then it works so there is something with the WebBrowser control, maby AdobeReader.

Is this a known error??

DocumentWindow code:

<docking:DocumentWindow x:Class="ToolDraw.UI.Popups.DrawingPopup"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

            <Border HorizontalAlignment="Stretch" CornerRadius="5" BorderThickness="2" Margin="3" BorderBrush="#FF595959" VerticalAlignment="Stretch">
                <Grid VerticalAlignment="Stretch" HorizontalAlignment="Stretch">
                    <WebBrowser Margin="3" VerticalAlignment="Stretch" Helpers:WebBrowserHelper.BindableSource="{Binding CurrentSelectedDrawingFile.LocalDrawingFileName}" />
                </Grid>
            </Border>
        </Grid>
    </Border>
    
</docking:DocumentWindow>
C# Code:

var dockSite = ((DockingMainWindow) _viewAwareStatus.View).dockSite;
            var window = new DrawingPopup();
            dockSite.DocumentWindows.Add(window);
            
            //var window = new DocumentWindow(dockSite, null, item.LocalDrawingFileName, null, control);
            window.Open();

Hi Patrik,

Sorry, this isn't something that has been reported before. But it sounds like it's an issue relating to the WebBrowser and/or Adobe Reader, and not our controls. I'd recommend you try reporting this to Microsoft, as they would ultimatley have to provide any fix.
