	In VSDB when a breakpoint is hit the edit window jumps to that line of code and the breakpoint symbol on the left is overlaid with an arrow indicating that the code is stopped at that point. Can this not be done from the VMDB plug-in? I know that the line number is given in the Output window but the marker would be nice. (another cosmetic request )

	Yes I would like that but can't find how to do it, hence the code line is highlighted instead

	Have you asked on MSDN? They are not nearly as responsive as you are here, but if there is a way, someone will probably point it out.

	Good idea. I don't think i did. I can never work out where to ask questions on msdn, usually ask in the wrong place and get frustrated. Do you have a link please? I know it sounds silly but I'm a million miles an hour at the moment. Would like to ask the question but haven't got time to wade through any confusion. Appreciated it you know.

	I do not know it off the top of my head, but I will poke around and let you know what I find.

	I went to msdn.microsoft.com and clicked on Forums.� From there I did a search on "writing debugger extensions" had a number of hits which lead me to this article, Creating a Custom Debug Engine. http://msdn.microsoft.com/en-us/library/bb145934(v=vs.110).aspx Next I did a search on "custom breakpoint marker" and turned up this thread. http://social.msdn.microsoft.com/Forums/en-US/vsdebug/thread/875134be-33be-4cbb-... and this http://social.msdn.microsoft.com/Forums/en-US/vsx/thread/4859c58c-0773-4c91-98ff... Seems like there are many relevant threads from that search.� You can backtrack from one of the threads to the top of the sub-forum, or use the Ask a question controls at the top of each thread. BTW, as responsive as you are in your own forums I'm not surprised your going a million miles an hour.� I don't see when you would have time to code!

	Thanks for the links they will be useful at some stage, it all came flooding back when I read them. To implement the marker I need to write a simulated debugger for the system so that I can implement the IDebugStackFrame2 interface. According to the links I need to do some stuff like this before the interface can be used Quote: 1. The OnModuleLoad event sent to the SDM. 2. The OnLoadComplete event sent to the SDM. 3. The OnBreakpoint event sent to the SDM The interface is only available as follows:- Quote: This interface is obtained only when the program being debugged has been stopped at a breakpoint (either caused by a user-set breakpoint or an exception). From this interface, an expression context can be obtained to evaluate expressions, a list of registers can be returned, or the call stack can be obtained and examined. So know I know why I gave up I think I found a few open source debugger examples but it was going to be a time consuming task to wade through and hook everything back to the arduino project (let alone understand how it all works). Since then the vm debugger has matured which might make the task easier. This post has been a good reminder thanks and will be useful when I or ano (hint everyone) take a look at it. Thanks for the note about the responses, sometimes it slows things down but at others it reminds me what is important. You can see why the web site and documentation is poor. I need to do a doc that's next on my list
