Random Debugging Goodies - (Jackson Davis's Blog)

I have uploaded another walkthrough for the new debug engine sample. This one explains breakpoints, breakpoint binding and stopping events in the sample engine. It is available along-side the other walkthroughs and the actual sample download at http:...

The Visual Studio Debugger team has just released a QFE that fixes several problems with the debugger in VS 2008. This fixes several issues while debugging multi-threaded applications in both managed and native code as well as some issues with breakpoints...

The Debug engine sample available at http://code.msdn.microsoft.com/debugenginesample has been updated for VS 2010. Changes include porting to use Microsoft.VisualStudio.Debugger.InteropA.dll as the primary PIA, updating registration to load in VS 2010...

One feature that is clearly missing from the current debug engine sample is stepping. The reason it is missing is it only requires one AD7 method to initiate the step and one AD7 event when the step is complete. However, the actual implementation of stepping...

I just released a new sample for writing a Visual Studio Debug Engine. The new engine sample is available at: http:// code.msdn.microsoft.com/debugenginesample This sample ships under the Microsoft Public License which means there is no warentee or...

I have written a guided walkthrough for the new Debug Engine Sample available in VSIP. The walkthrough contains a high-level architecture description and a source code walkthrough of how the sample engnes launches debug processes. It demonstrates: launching...

I have uploaded another walkthrough for the new debug engine sample. This one explains threads and modules in the sample engine, the AD7 events corresponding to them, and the objects that implement them. It is available along-side the other walkthroughs...

I found this old blog post on my box today. I had never gotten around to posting it.Hopefully, this will be useful to someone. In my last SOS post I promised to give a discussion on the CLR data structures you need to debug managed code with SOS...

One little known feature of Visual Studio 2005 is its ability to load and use the SOS debugging extension. SOS (Son of Strike) is an extension for the debuggers available in Debugging Tools for Windows that makes it possible to symbolically debug managed...

One thing we get a lot of reports about from people writing custom debug engines is if the engine is doing engine launch (using LaunchSuspended like the engine sample does) and the engine doesn't launch a true win32 process, the debugger will fail the...

I get a lot of questions about port suppliers from people who are attempting to write a debug engine. There appears to be a lot of confusion on the subject. IMHO, the concept of Port, and PortSupplier is one of the most confusing aspects of the AD7 architecture...

Ian Huff (a developer on Intellitrace) just published a nice article on that new feature of VS 2010. If you're curious about the how Intellitrace works and how it can help track down "no-repro" bugs, this is a good read: http://visualstudiomagazine...

A fix for a widely reported crash in the Visual Studio 2008 SP1 IDE is now available. This fixes a crash that occurs after changing layouts and then changing modes. The layout changes can be undocking/docking windows, and the mode changes are starting...
