Hi Joe, the first exception I believe is something to do with mixing unmanaged with managed code (shouldn't be the qualifier 'unsafe' used??? - sorry, but don't know the tricks of mixing unmanaged with managed code)
But, have a look here http://forum.openscenegraph.org/viewtopic.php?t=13944 , it was for C# sample.The unmanaged code is wrapped into dll of exposing a function (unmanaged) that is initializing and running the viewer from unmanaged dll. The second exception is I believe you are not setting the inheriteddata. If you still want to try with mixing managed and unmanaged, You don't need to set up the viewer as embedded. Only pass the handle of the form's client area - something like traits->inheritedWindowData = new osgViewer::GraphicsWindowWin32::WindowData(this->Handle->ToInt32()) in your form init Nick On Mon, Jul 7, 2014 at 10:42 AM, Bluish Joe <mirco.andr...@tesigroup.it> wrote: > Hi Trajce, very kind! > It's managed C++ (even if I would finally use OSG in a C++Builder > application, but I fear I will need to build OSG in Visual Studio and make > a a wrapper.......). > > I tried many examples.
