Evaluate an expression while debugging a dump file in WinDBG or Visual Studio

I know that the answer is probably no, but since I am slightly desperate, I ask in case there is some trick I don't know.

I need to call a function while debugging a dump file, but apparently this is impossible either using windbg or visual studio on windows.

any hope for me?

Solution

  • I struggle to see how this is possible.

    A dump file, in it's basic form, is a collection of data, not an executable environment. If you try to call a function using, say, .call in WinDbg, whilst looking at a dump file, you will likely get this message:

    No runnable debuggees error......

    or something like that.

    In order for you to call a function, the program's code must be loaded into a memory address that can be executed against. In other words, you must open/attach a debugger to the running process (.exe, etc) you wish to interact with.
