How to click a outer link, and it will open the application to open the link.
How to deliver a url string to the application and it will be opened by the app ?
Thank you!

If you click on a HTTP/HTTPS link then you need to set your application as the default web browser in that computer.

Then get URL from the parameter using ParamStr :

If the appliccation is running, how to get the clicked url outside, thank you!

There is another problem, I cannot use single app. May be because the CreateGlobalCEFApp?

var
hMutex: THandle;
begin

hMutex := CreateMutex(nil, False, 'TheStandard');
if GetLastError = ERROR_ALREADY_EXISTS then
begin
CloseHandle(hMutex);
MessageBox(0,'You can not run a second copy of this App','',mb_OK);
application.Terminate;
end;

If your app is the default web browser it will be executed by windows and the URL will be in ParamStr.
