用CreateDesktop新建一個(gè)桌面，什么都沒(méi)有的桌面，然后在新桌面環(huán)境中運(yùn)行了explorer所以就有了和windows一樣功能的桌面，這個(gè)時(shí)候你就有了兩個(gè)桌面了，下面要做的就是用SwitchDesktop切換不同的桌面了

在不同桌面中打開(kāi)的程序在其他桌面的任務(wù)欄包括系統(tǒng)托盤(pán)上不可見(jiàn)，不過(guò)任務(wù)管理器中還是可見(jiàn)的這樣你就非常方便的做很多事了，很多...  而且還可以非?？斓霓D(zhuǎn)到正常狀態(tài)上可以讓會(huì)責(zé)罵你的人比如老板什么的無(wú)話可說(shuō)，因?yàn)樗麄兪裁匆部床坏?nbsp; : )

或者你也可以給你用戶定制一個(gè)個(gè)性化的桌面。改改上面的代碼可以得到你要的效果的。
