windows - TWebbrowser 中的点击声音

Question

来自这个答案 CoInternetIsFeatureEnabled in Delphi2010

有谁知道如何停止滴答声。当我将它放入单独的 pas 文件时，这在 Delphi XE 中似乎不起作用。有一些缺失。以及它无法编译的其他原因，所以我有点卡住了。

这是我所做的。

unit untUrlMon;

interface

uses
    Windows;

const
  GET_FEATURE_FROM_THREAD = $00000001;
  GET_FEATURE_FROM_PROCESS = $00000002;
  GET_FEATURE_FROM_REGISTRY = $00000004;
  GET_FEATURE_FROM_THREAD_LOCALMACHINE = $00000008;
  GET_FEATURE_FROM_THREAD_INTRANET = $00000010;
  GET_FEATURE_FROM_THREAD_TRUSTED = $00000020;
  GET_FEATURE_FROM_THREAD_INTERNET = $00000040;
  GET_FEATURE_FROM_THREAD_RESTRICTED = $00000080;

  SET_FEATURE_ON_THREAD = $00000001;
  SET_FEATURE_ON_PROCESS = $00000002;
  SET_FEATURE_IN_REGISTRY = $00000004;
  SET_FEATURE_ON_THREAD_LOCALMACHINE = $00000008;
  SET_FEATURE_ON_THREAD_INTRANET = $00000010;
  SET_FEATURE_ON_THREAD_TRUSTED = $00000020;
  SET_FEATURE_ON_THREAD_INTERNET = $00000040;
  SET_FEATURE_ON_THREAD_RESTRICTED = $00000080;

  INTERNETFEATURELIST = (

function CoInternetIsFeatureEnabled(FeatureEntry: INTERNETFEATURELIST; dwFlags: DWORD): HRESULT; stdcall; external 'urlmon.dll'

implementation

function CoInternetSetFeatureEnabled(FeatureEntry: INTERNETFEATURELIST; dwFlags: DWORD; fEnable: BOOL): HRESULT; stdcall; external 'urlmon.dll'

begin
  if CoInternetIsFeatureEnabled(FEATURE_DISABLE_NAVIGATION_SOUNDS, GET_FEATURE_FROM_PROCESS) = S_FALSE then
    CoInternetSetFeatureEnabled(FEATURE_DISABLE_NAVIGATION_SOUNDS, SET_FEATURE_ON_PROCESS, True); 
end;

Answer 1

我想你需要这样的东西:

unit untUrlMon;

implementation

uses
  Windows;

const
  SET_FEATURE_ON_PROCESS = $00000002;
  FEATURE_DISABLE_NAVIGATION_SOUNDS = 21;

function CoInternetSetFeatureEnabled(FeatureEntry: DWORD; dwFlags: DWORD; fEnable: BOOL): HRESULT; stdcall; external 'urlmon.dll';

initialization
  CoInternetSetFeatureEnabled(FEATURE_DISABLE_NAVIGATION_SOUNDS, SET_FEATURE_ON_PROCESS, True); 

end.
