It is reproducible in CefClient. If you don't load start page and call LoadString directly, the page itself is not getting loaded. Attached cefclient.patch file.

It has been created in version CEF3 1271.

We have spend some time trying to port from CEF 1 to CEF 3 . This has been a good amount of work due to the multi-process architecture requiring to implement custom marshalling...we are almost finishing but now just found out that some fundamental functions like LoadString (this issue and 579) has not worked properly since 2012.

Initially we used following build: cef_binary_3.1547.1412_windows32
LoadString worked fine with supplied http URL. But I can not make it to work when supply some file URL. I tried following:
file:///dummy.html (this works with CEF1)
file:///C:/dummy.html
file:///C|/dummy.html

Then we tried to update to following build: cef_binary_3.1621.1450_windows32
Now we can not make LoadString to work at all even with http URL.

We trying to call LoadString in OnAfterCreated and in OnBeforeBrowse callbacks in following way:

CefString Content = L"test page";
CefString Url = L"http://localhost";
browser->GetMainFrame()->LoadString(Content, Url);

Any ETA on a fix for LoadString ?

@ commentcomment 5.: LoadString is inherently flawed due to the requirement of creating render processes -- you're better off using standard network loading (browse to a URL and handle via a custom scheme handler or GetResourceHandler). See https://code.google.com/p/chromiumembedded/wiki/GeneralUsage.

@ commentcomment 6.: Thank you very much for the explanation and advise. I already finished implementing using this method and getting ready to test it.
