二級VB輔導(dǎo)：用VB實現(xiàn)“一點即填”

在申請 Email 信箱、主頁空間時我們經(jīng)常要填寫表 單，比如要填姓名、住址、身份證號、E-mail 地址、個人 簡介等等??每次都重復(fù)的填寫，好煩哪！
    面對這種情況，大家可能首先想到的是上網(wǎng)上找一款 填表軟件。但現(xiàn)有的軟件不是用剪貼板傳遞就是采用拖放技 術(shù)，而且使用時必須運行填表軟件，使用起來并不是很方便。 因此我們決定自己編寫一個軟件，將它集成到IE的右鍵菜單 里，使用時只要在要輸入的輸入項上單擊鼠標(biāo)右鍵，然后選 擇相應(yīng)的項即會自動輸入，從而實現(xiàn)“一點即填”。
    本程序首先要在IE的右鍵菜單上添加項目，這可通過 操作注冊表來實現(xiàn)，然后利用一個JavaScript程序判斷所選 的是不是可輸入框，如果是，將我們事先保存的數(shù)據(jù)填上。 下面介紹具體的實現(xiàn)過程。
    一、設(shè)計界面
    進入 VB，選擇“標(biāo)準(zhǔn) EXE”新建一工程，選擇“工 程”菜單下的“部件”，在彈出的對話框中選擇“Microsoft Windows Common Controls 6.0”，然后按照下表在窗體 上添加控件，設(shè)置完成的界面如圖 1 所示：
    控件類型 Name 屬性
    標(biāo)簽 label1 Caption：名稱 標(biāo)簽 label2 Caption：內(nèi)容 文本框 txtname
    文本框 txtcont
    命令按鈕 command1 Caption：添加 命令按鈕 command2 Caption：刪除 列表框 listview1 為它加入兩個列，列標(biāo)題分別為“名稱”和“內(nèi)容”，并
    且把 View 屬性修改成 3-lvwReport，把 GridLines 改成 True。
    二、程序源代碼
    首先在工程中添加一個標(biāo)準(zhǔn)模塊并輸入如下代碼，這 些代碼用于注冊表操作：
