從 Visual Basic 6.0 CD-ROM（安裝目錄） 中獲取 OLE 自動化類型庫生成器。若要執(zhí)行此操作將所有四個文件從 /Common/Tools/VB/Unsupprt/Typlib/ 文件夾復制到您的項目文件夾中。

將以下文本復制到記事本，，將文件保存為 Objsafe.odl 項目文件夾中：

[

????????? uuid(C67830E0-D11D-11cf-BD80-00AA00575603),

????????? helpstring("VB IObjectSafety Interface"),

????????? version(1.0)

????????????? odl

????????? ]

????????? interface IObjectSafety:IUnknown {

????????????? [helpstring("GetInterfaceSafetyOptions")]

????????????? HRESULT GetInterfaceSafetyOptions(

??????????????????????? [in]? long? riid,

??????????????????????? [in]? long *pdwEnabledOptions);

????????????? [helpstring("SetInterfaceSafetyOptions")]

????????????? HRESULT SetInterfaceSafetyOptions(

??????????????????????? [in]? long? riid,

??????????????????????? [in]? long? dwOptionsSetMask,

??????????????????????? [in]? long? dwEnabledOptions);

?????????? }

?????? }

?

在命令提示符使用 CD <path>

?將移動到項目文件夾，然后鍵入以下命令來生成.tlb 文件的命令：MKTYPLIB objsafe.odl /tlb objsafe.tlb

利用tlb注冊工具將文件注冊?

從 Visual Basic 創(chuàng)建 ActiveX 控件項目

在 項目 菜單上單擊 引用 ，瀏覽到并添加 Objsafe.tlb，您早先創(chuàng)建的。

添加一個新的模塊到您的項目與下面的代碼并命名模塊 basSafeCtl

Option Explicit

????? Public Const IID_IDispatch = "{00020400-0000-0000-C000-000000000046}"

????? Public m_fSafeForInitializing As Boolean

????? Sub Main()

????????? m_fSafeForScripting = True

????????? m_fSafeForInitializing = True

在工程屬性中把啟動對象改成Sub Main確保上述代碼會被執(zhí)行。m_fSafeForScripting 和m_fSafeForInitializing兩件變量的值分別指定了腳本安全和初始化安全取值。

打開您的控件的代碼窗口。將下面的代碼行添加到聲明部分中

Implements IObjectSafety

將下面的兩個過程復制到您的控件的代碼

生成.ocx控件，用web頁面引用。控件與頁面交互時IE不再提示安全問題。
