Hi,

If you are loading a local html file with a file:/// URL, you will have some restrictions.
Chromium do that for safety reasons and that's why it's recommended to load local files in CEF with a custom resource handler.

Check the CustomResourceBrowser demo.

Hello,I have tried load it from Chromium_OnGetResourceHandler
if request.Url = 'http://printerpage/' then
begin
TempStream := TFileStream.Create(ExtractFilePath(Application.ExeName) +
'printerpagesetting.html',fmOpenRead);//which has a swf embedded in it
Result := TCustomResourceHandler.Create(browser, frame, '', request,
TStream(TempStream), CefGetMimeType('html'));
end
else if request.Url = 'http://printerpage/flashwithprintbutton.swf' then
Begin
TempStream := TFileStream.Create(ExtractFilePath(Application.ExeName) +
'flashwithprintbutton.swf',fmOpenRead);//press the button will show system printer setting well in ie(win10)
Result := TCustomResourceHandler.Create(browser, frame, '', request,
TStream(TempStream), CefGetMimeType('swf'));
end;

But the flash button still have (no right?) to show printer setting, what's wrong or any other solution

I know nothing about Adobe Flash programming but If you can't find a way to make it work you can also try the other workarounds for this kind of issues :

• Use a custom scheme. You could use URLs that start with 'myprotocol://' instead of 'http://' and load your contents from disk. Take a look at the SchemeRegistrationBrowser demo for more info.
• Another suggested workaround is using DATA urls.

Sorry for this, I have to add some information:
I test it in Chrome,IE,and Firefox, they can load and run print setting using file://......html , so i think it no need to understand how flash program it.....
but it can't work well in Cef4delphi demo browser...

Why?
I'm sorrry, but could you give us some demo on printer call (beside the window.print() using js )

thank you very much!

I'll take a look this weekend but I can't promise anything because I know nothing about Flash programming...
