Answer 1

2. 调用方法:
WebBrowser.ExecWB nCmdID, nCmdExecOpt, [pvaIn], [pvaOut]
3. 参数说明:
(a).nCmdID
OLECMDID_OPEN = 1,
OLECMDID_NEW = 2,
OLECMDID_SAVE = 3,
OLECMDID_SAVEAS = 4,
OLECMDID_SAVECOPYAS = 5,
OLECMDID_PRINT = 6,
OLECMDID_PRINTPREVIEW = 7,
OLECMDID_PAGESETUP = 8,
OLECMDID_SPELL = 9,
OLECMDID_PROPERTIES = 10,
OLECMDID_CUT = 11,
OLECMDID_COPY = 12,
OLECMDID_PASTE = 13,
OLECMDID_PASTESPECIAL = 14,
OLECMDID_UNDO = 15,
OLECMDID_REDO = 16,
OLECMDID_selectALL = 17,
OLECMDID_CLEARselectION = 18,
OLECMDID_ZOOM = 19,
OLECMDID_GETZOOMRANGE = 20
OLECMDID_updateCOMMANDS = 21
OLECMDID_REFRESH = 22
OLECMDID_STOP = 23
OLECMDID_HIDETOOLBARS = 24
OLECMDID_SETPROGRESSMAX = 25
OLECMDID_SETPROGRESSPOS = 26
OLECMDID_SETPROGRESSTEXT = 27
OLECMDID_SETTITLE = 28
OLECMDID_SETDOWNLOADSTATE = 29
OLECMDID_STOPDOWNLOAD = 30
上面的关键词都可以在浏览器的菜单里面找到对应的选项﹐大家一看就明白的﹗
(b).nCmdExecOpt
OLECMDEXECOPT_DODEFAULT = 0, //默认
OLECMDEXECOPT_PROMPTUSER = 1, //提醒用户
LECMDEXECOPT_DONTPROMPTUSER = 2, //不提醒用户
OLECMDEXECOPT_SHOWHELP = 3

所以我觉得第二个参数应当是2，也就是
document.all.WebBrowser.ExecWB(6,2);

追问

第二个参数是2也会提示
