Hi Jacek:
The latest wine can call BeforeNavigate2event now. 
But on windows the BeforeNavigate2event can be called two times,
the first is : "BeforeNavigate2:app:meihua ", 
the second is: "BeforeNavigate2:res://ieframe.dll/unknownprotocol.htm#app:meihua"
I will try to add a handle as you advice.

Thank you very much.

Hi Changhui,

No, there is no such thing as app protocol handler on Windows and we shouldn't have one. This means that loading will (correctly) fail for this protocol, but BeforeNavigate2 should happen before it has a chance to fail. To support that, we have our own onclick handler for anchor elements, where we initiate loading. See HTMLAnchorElement_handle_event in htmlanchor.c.

I tried your test app and it works find for me with recent Wine. Are you testing it against current Git?

I found that the real reason is urlmon!get_protocol_cf return MK_E_SYNTAX(0x800401e4) when it open this registry key “HKEY_CLASSES_ROOT\PROTOCOLS\Handler\app” failed.
Do you think the right way is implement a new 'app:' protocol handle like "HKEY_CLASSES_ROOT\PROTOCOLS\Handler\http"?

Thank you!

Hi, this verify test need the user click the app: hyperlink in browser,
so it is hard to write a test in dlls/ieframe/tests.

I upload the test html file and a test exe here:

To run the test, extract mfc_web.zip, then run the mfc_web.exe, click the Go button;
A message "BeforeNavigate2 app:xxx" will popup when click the app: hyperlink 
if the BeforeNavigate2 event was triggered as like IE in windows, or nothing.

It doesn't seem right. There is nothing special about app: protocol handling, BeforeNavigate2 should be called in this case the same way as for any other protocol. You need to find the real reason why it's not called instead of calling it in an error case. The bug is likely to be in mshtml.
