VS-2019 Debugging MFC

VS-2019 Debugging MFC

David Webber 136

I'm using MFC as a shared DLL in a program with an EXE and a number of my own DLLs, some of which use MFC.

Using VS-2019, when I step through my program's DEBUG build, it won't step into the MFC library source code.

How do I get it to do so?

Do you have the "just my code" debugging option set?

In addition to unchecking "Just My Code" you will also need to setup up the debugger to load the symbol files for the MFC Dlls. specify-symbol-dot-pdb-and-source-files-in-the-visual-studio-debugger

Thank you,

I've checked that justMyCode is unset in both the VS Debug/Options menu and in each of the project properties.
And following your link I now seem to be downloading the .pdb's from Microsoft. (I need to try and use the versions on my computer so I can work off line, but we're OK for now.) Thanks.

Hi @David Webber ,

As RLWA32's answer, you could specify the symbol file location in debugging options, and vs will load it for your mfc DLL.

You can use the MFC symbol files that were installed with Visual Studio. In the debugging options uncheck the Microsoft Symbol Server and add the path to the symbol files that were installed with Visual Studio.
For example, in a VS2017 installation (32 bit VM) the locally installed MFC symbol files are used as follows -

Of course you would specify the appropriate path on your own system to use the local files.
