Debugger extensibility: how to set editor to read-only in debug mode?

Question

Hi,

we created a custom debug engine and now want to set the editor windows to read-only because we do not want to support edit-and-continue.

What is the easiest way to achieve this?

What we did is: we manually set the editor windows to read-only. We tried two different ways: either by calling method SetStateFlags of IVsTextLines or by calling FindAndLockDocument of IVsRunningDocumentTable. Both work, but have an ugly side effect: when the file is already open in the editor in debug mode and you double-click on the file name in the solution/project explorer, you get a popup saying "The document ... is already open. Do you want to close it?".

So: how can we get rid of this popup or is there another way to set editor windows to read-only during debugging that does not have this side-effect?

By the way: the editor windows stay editable for both J. Davis' sample engine (http://archive.msdn.microsoft.com/debugenginesample) as well as for IronPythonTools.

Thanks and best regards,

Bernhard
