What does Internet Explorer do to notify other browsers about proxy settings change?
c++, google-chrome, internet-explorer, proxy, windows
Solution
You must send broadcast message WM_SETTINGCHANGE
upd. Parameters must be set to null like this: SendNotifyMessage(HWND_BROADCAST,WM_SETTINGCHANGE,(WPARAM)(0),(LPARAM)(0));
Or you can use InternetSetOption fuction from WinInet library like this: InternetSetOption(NULL,INTERNET_OPTION_SETTINGS_CHANGED,NULL,0);
Problem
I've come to a strange behaviour, if I change proxy settings on Windows 7 in ``` HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings ``` Google Chrome acts like nothing happened - even after restarting it. However when I start/restart Internet Explorer, somehow it "tells" Chrome about the changes and suddenly Chrome starts to use the proxy settings - even without restarting Chrome. What does Internet Explorer "do" so Chrome notices that? Is something similar, something that IE Explorer do, achieveable in C++ ? PS: `RegNotifyChangeKeyValue` does not seem to be the thing...
