How to access prefs in wWinMain

[Hoài Nông]

Hi every one,

Could you help me access prefs in wWinMain.

My code (chrome\app\chrome_exe_main_win.cc):

#include "components/prefs/pref_service.h"

#include "chrome/browser/profiles/profile_manager.h"

....

int APIENTRY wWinMain(HINSTANCE instance, HINSTANCE prev, wchar_t*, int) {

...

const std::string test1 = ProfileManager::GetActiveUserProfile()->GetPrefs()->GetString("test.prefs_1");

...

}

Error:

lld-link: error: undefined symbol: public: static class Profile * __cdecl ProfileManager::GetActiveUserProfile(void)

>>> referenced by .\..\..\chrome\app\chrome_exe_main_win.cc:309

>>>               obj/chrome/chrome_initial/chrome_exe_main_win.obj:(wWinMain)

Thank!

Hi. You can't do that for many reasons.

Could you explain what it is that you're trying to accomplish by accessing a Profile's preferences in chrome_exe_main_win.cc? Perhaps we can help you find a different way to achieve your goal.

Prefs are a fine way to save state, but that needs to be done from within the context of the browser process after Local State and/or Profile preferences have been brought up. chrome_exe_main_win.cc is used for all process types and is far, far too early to do anything relating to prefs. I suggest you look for a place in src/chrome/browser to do your work. ChromeBrowserMainParts is a thing that does various bits of work during browser process startup/shutdown. CreatePrimaryProfile is the thing that ordinarily creates the first Profile. Maybe that'll give you some clues.

I'm afraid that's outside of my field. You could try searching around in https://source.chromium.org/chromium. Otherwise, hopefully someone else here on the list can point you in the right direction.
