.NET Forum / Visual Studio.NET / Extensibility / March 2008debug engine, frame omission optimization vs local symbols
with frame pointer omission, EBP is not used to address local variables. The Visual C/C++ debugger gives a message "vCX0069 - variable needs stack frame" in this case. In my Visual Studio debug engine, I would like to give a similar message. How can I detect this situation? Hi Jan, Regarding on the display a "vCX0069 - variable needs stack frame" like message in Visual Studio, do you mean you want to develop a debug assistant or any other extension component in Visual Studo that will do the detection? If convenient, would you provide more about the background of the component you want to write and the detailed about the problem you meet and the result you expect? Thus, I can help you do some further research on that.

Hello Steve, using the VSIP SDK / VSSDK, we have our own debug engine that provides debugging to our own project type in Visual Studio (Gregg M should remember this, if he is still there). We just discovered this problem: when the user enables frame omission optimization, we can no longer display variables in the watch window. The C/C++ debugger marks this with the message I mentioned below and I would like to do the same. But I have not figured out yet how to detect the frame omission optimization at execution time. Regards, Jan > Hi Jan, > [quoted text clipped - 51 lines] > >in this case. In my Visual Studio debug engine, I would like to give a > >similar message. How can I detect this situation? Hi Jan, Thanks for your reply. Currently, I'd like to leverage some further resources so as to help you address this issue. Would you send me an email to the following address: "stcheng" + "@" + "microsoft.com" I'll collect some further information from you offline.

Are you using dbghelp symbol API's, or the DIA sdk? This is going to be a bit tricky to try and figure out, because our own native DE and C++ EE uses the private MSPDB api's. So trying to use the VC++ EE as a reference probably won't help much in this instance. Thanks, Ed Dore [MSFT] Hello Ed, I am using dbghelp.dll version 6.5.3.7, but could not find anything in there that helps me.
