The following code crashes my Managed DirectX app but only when DirectX is in debug mode...

[source lang = "c#"]
                Color bg = Color.Transparent;
               // Color bg = Color.Black;

                if (this.clearRequired)
                {
                    this.initializer.Device.Clear(ClearFlags.Target, bg, 1, 0);
                    this.clearRequired = false;
                }

Anybody know how this could happen? Thanks in advance, Devin

This is probably one of the debug assertations. Since you use the debug runtimes you ought to see a nice error description in the debug output view.

This usually indicates a wrong parameter or state.

Thanks, but what's the debug output view? Is that something in DirectX or Visual Studio?

I believe he's referring to the Output window in Visual Studio, at the bottom of the screen.

Yep, sorry, i meant the default output view of Visual Studio.

Note that on assertations i sometimes have to press Ignore once to actually get the debug info in the output view. I don't know if that applies to managed DirectX as well.

OK. I see now. I wasn't sure what the output window even was. I'm somewhat new to VS and am still learning. I usually get the debug window and fix the errors I see in that window. But this is the portion that has errors in the output window (I'm not sure what to do with it though? Help?)...
