HTMLID_FIND = 1;
//查找对话框
HTMLID_VIEWSOURCE= 2; //查看源代码
HTMLID_OPTIONS =3;
//Internet选项
procedure WB_FindDialog(WebBrowser: TWebbrowser;
nCmdId:Cardinal);overload;
var
CmdTarget : IOleCommandTarget;
vaIn, vaOut: OleVariant;
PtrGUID: PGUID;
begin
New(PtrGUID) ;
PtrGUID^ := CGID_WebBrowser;
if WebBrowser.Document <> nil
then
try
WebBrowser.Document.QueryInterface(IOleCommandTarget, CmdTarget)
;
if CmdTarget <> nil
then
try
CmdTarget.Exec(PtrGUID, nCmdId, 0, vaIn, vaOut) ;
finally
CmdTarget._Release;
end;
