Embedding dual CEF browsers

[dapu92]

Hello, i am making an application in which the user is supposed to log in and then fetch list of url and then surf those url. So far i have managed to create two embedded browser by using CreateBrowserSync() and i am making the first browser go small once the user has logged in and then it surfs the pages in another browser which earlier was of size 0. Now the issue is if i close the application, the application crashes some times.

I am using following :

WM_CLOSE : CefQuitMessageLoop() return 0;
WM_DESTROY:return 0;

Please let me know what all information i need to provide other than this. This is my first question on this forum, so i am not sure how exactly to ask and what details are needed to be provided.

You should wait for OnBeforeClose to be called for all browsers before quitting the message loop.

Actually it crashes while surfing also, say after 8 hours or sometimes like 3 hrs and some times after 13 hrs. But onBeforeClose() will not solve it, can you suggest me any fix for that too.

Actually it crashes while surfing also

What is the symbolized call stack for this crash?

I will run it again using visual studio, and then will take screenshot once it crashes and will post here. Thanks for replying !

Hello, i got dump of crash and this was the call stack of that. I got almost same dump 3 times and other than those 3 it had crashed earlier two times in those two other dump the call stack was referring to avcu32.dll(Bitdefender). So i uninstalled the AV and other stuff and then i got the following.

The issue i am facing is that it runs perfectly on Win7 but when it is running on Win8/Win8.1 then it is good until i maximize window and leave it for sometime. I tried on laptop with WIn8.1 installed and Win8 & win8.1 in a VM. If you want i can post my handler and main file code here too.

What CEF version are you using?

I am using cef 3.2171.1979 which came with binary.

Also i have one more question, shall i create another one or ask here ? the question is how to disable web security, i tried passing commandline argument --disable-web-security but no use. Basically i am trying to show the facebook, youtube in iframe.So far i have learnt that I have to either disable web security or modify response headers to allow cross origin access. Thank you for quick replies.
