windows – Delphi2010中的CoInternetIsFeatureEnabled

我试图在WebBrowser控件中单击链接时停用恼人的声音,而不更改用户注册表.我发现文档可以通过 CoInternetIsFeatureEnabled完成,也解释了 here.但我不知道如何在Delphi 2010上实现它,因为我在将URLMon单元包含到项目中后得到“未声明的标识符”错误并且没有太多文档在那里.

有任何想法吗？

CoInternetIsFeatureEnabled()和CoInternetSetFeatureEnabled()不包含在D2010的UrlMon.pas副本中.您必须手动声明它们,例如：

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; 

type
  INTERNETFEATURELIST = (
    FEATURE_OBJECT_CACHING,FEATURE_ZONE_ELEVATION,FEATURE_MIME_HANDLING,FEATURE_MIME_SNIFFING,FEATURE_WINDOW_RESTRICTIONS,FEATURE_WEBOC_POPUPMANAGEMENT,FEATURE_BEHAVIORS,FEATURE_DISABLE_MK_PROTOCOL,FEATURE_LOCALMACHINE_LOCKDOWN,FEATURE_SECURITYBAND,FEATURE_RESTRICT_ACTIVEXINSTALL,FEATURE_VALIDATE_NAVIGATE_URL,FEATURE_RESTRICT_FILEDOWNLOAD,FEATURE_ADDON_MANAGEMENT,FEATURE_PROTOCOL_LOCKDOWN,FEATURE_HTTP_USERNAME_PASSWORD_DISABLE,FEATURE_SAFE_BINDTOOBJECT,FEATURE_UNC_SAVEDFILECHECK,FEATURE_GET_URL_DOM_FILEPATH_UNENCODED,FEATURE_TABBED_BROWSING,FEATURE_SSLUX,FEATURE_DISABLE_NAVIGATION_SOUNDS,FEATURE_DISABLE_LEGACY_COMPRESSION,FEATURE_FORCE_ADDR_AND_STATUS,FEATURE_XMLHTTP,FEATURE_DISABLE_TELNET_PROTOCOL,FEATURE_FeedS,FEATURE_BLOCK_INPUT_PROMPTS,FEATURE_ENTRY_COUNT
  );

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