[Solved] Cannot get any multi-process code to load a page.

Your code doesn't make a whole lot of sense. How about you start at the beginning?

What are you trying to achieve? What platform are you using? What frameworks/technologies?

I'm just trying to get the bare bones needed to implement off-screen-rendering and JavaScript support on Windows (with an eye to Linux and Mac later). There's basically nothing implemented in my sample code because I'm just trying to get to grips with CEF3. That's why my handlers are just log statements and a couple stubbed in values - I want to see what CEF3 is doing.

I've read the cefsimple, cefclient, and other samples. I don't see what I'm doing that they're not... or vice versa.

Can you roughly explain how cefsimple is structured? Where is the browser created?

Are you integrating with an existing message loop?

Yeah. cefsimple on Windows starts in the cefsimple_win.cc file. It sets up CEF, hands it an instance of SimpleApp from simple_app.cc, and enters the message loop. SimpleApp creates the browser instance in the OnContextInitialized callback.

Based on this, it might be possible I'm creating a browser before CEF is ready. Although I'd expect to get no callback events in that case.

And, yes, I want to use an existing message loop. Eventually this will land in a game engine.

Waiting on the context does not change the behavior.

Off-screen rendering is necessarily complex and will not work if you implement the callbacks incorrectly. I suggest you start with a working example and go backwards from there instead of trying to implement it from scratch. There are examples in cefclient and a number of existing game engines (you can Google for those).

The OSR part doesn't bother me. I can't even get the main loop to run properly. Why does it work single-threaded but not multi-threaded?

[ScottD]

Solved! I've been using QtCreator as an IDE. Turns out you MUST use the manifest file on Windows or CEF is very unhappy.

Stupid Windows.

Your renderer process was crashing. For future problems remember to consult generated log file and I would recommend VS on Windows with extension that enables you to debug child processes as well
