How to unload a PDB symbol?

Question

_{Sunday, April 19, 2015 9:27 PM}

I inadvertently loaded the PDB by checking "Microsoft Symbol Servers" in this page and pressing "Load" button -- screenshot here: http://tinypic.com/r/2hwh4du/8. Now when I debug my code (using step over), the crt0dat.c source is automatically opened and the execution flow enters into it. Very annoying. So what can I do to undo this? It seems that there is a "Delete" button there that seems to do the desired job, but I don't know how to open that "No Symbols Loaded" page again. Any help? Thanks a lot.

You can open during debugging 'Modules' window (Debug->Windows->Modules), right clicking respective module. There you may uncheck 'Always Load Automatically', then next time, when you start debugging pdb will not be loaded.
Or choose 'Symbol Settings ...' which opens Debugging / Symbols page (also reachable through 'Debug->Options' under 'Debugging' node choosing 'Symbols' ), where you may add module-name in 'Specify excluded modules'.
Here you can also add remove locations, where VS looks for symbols.

With kind regards
