我用vb做了一个ocx，在网站上运行用singcode对这个ocx进行了签名（我的证书是用 makecert做的）
用chktrust检查了也是正确的但我用Package & Deployment Wizard将这个ocx打成cab包后放在服务器上。
在客户机中使用的时候仍然必须改变ie的安全级别才能下载安装这个ocx
请问怎么解决这个问题

第二步：用VB自带的MKTYPLIB将编译成objsafe.tlb
MKTYPLIB objsafe.odl /tlb objsafe.tlb第三步：在工程中引用objsafe.tlb第四步：加入安全模块basSafeCtl到工程中

End Type Public m_fSafeForScripting As Boolean
Public m_fSafeForInitializing As Boolean Sub Main()

End Sub第五步：设置工程的启动属性为Sub Main第六步：在OCX工程的代码前加上Implements IObjectSafety以实现安全接口
第七步：拷贝一下两个过程到工程中 Private Sub IObjectSafety_GetInterfaceSafetyOptions(ByVal riid As _
Long, pdwSupportedOptions As Long, pdwEnabledOptions As Long)
Dim Rc As Long
Dim rClsId As udtGUID
Dim IID As String
Dim bIID() As Byte pdwSupportedOptions = INTERFACESAFE_FOR_UNTRUSTED_CALLER Or _
INTERFACESAFE_FOR_UNTRUSTED_DATA If (riid <> 0) Then
CopyMemory rClsId, ByVal riid, Len(rClsId) bIID = String$(MAX_GUIDLEN, 0)
Rc = StringFromGUID2(rClsId, VarPtr(bIID(0)), MAX_GUIDLEN)
Rc = InStr(1, bIID, vbNullChar) - 1
IID = Left$(UCase(bIID), Rc) Select Case IID
Case IID_IDispatch
pdwEnabledOptions = IIf(m_fSafeForScripting, _
INTERFACESAFE_FOR_UNTRUSTED_CALLER, 0)
Exit Sub
Case IID_IPersistStorage, IID_IPersistStream, _
IID_IPersistPropertyBag
pdwEnabledOptions = IIf(m_fSafeForInitializing, _
INTERFACESAFE_FOR_UNTRUSTED_DATA, 0)
Exit Sub
Case Else
Err.Raise E_NOINTERFACE
Exit Sub
End Select
End If
End Sub Private Sub IObjectSafety_SetInterfaceSafetyOptions(ByVal riid As _
Long, ByVal dwOptionsSetMask As Long, ByVal dwEnabledOptions As Long)
Dim Rc As Long
Dim rClsId As udtGUID
Dim IID As String
Dim bIID() As Byte If (riid <> 0) Then
CopyMemory rClsId, ByVal riid, Len(rClsId) bIID = String$(MAX_GUIDLEN, 0)
Rc = StringFromGUID2(rClsId, VarPtr(bIID(0)), MAX_GUIDLEN)
Rc = InStr(1, bIID, vbNullChar) - 1
IID = Left$(UCase(bIID), Rc) Select Case IID
Case IID_IDispatch
If ((dwEnabledOptions And dwOptionsSetMask) <> _
INTERFACESAFE_FOR_UNTRUSTED_CALLER) Then
Err.Raise E_FAIL
Exit Sub
Else
If Not m_fSafeForScripting Then
Err.Raise E_FAIL
End If
Exit Sub
End If Case IID_IPersistStorage, IID_IPersistStream, _
IID_IPersistPropertyBag
If ((dwEnabledOptions And dwOptionsSetMask) <> _
INTERFACESAFE_FOR_UNTRUSTED_DATA) Then
Err.Raise E_FAIL
Exit Sub
Else
If Not m_fSafeForInitializing Then
Err.Raise E_FAIL
End If
Exit Sub
End If Case Else
Err.Raise E_NOINTERFACE
Exit Sub
End Select
End If
End Sub第八步：编译后，打包的最后一步设置安全为TRUE,检查CAB中的INF文件是否有 HKLM,"SOFTWARE\Classes\CLSID\{DD8ECE41-DBF1-47F3-969C-2C86AFD8331A}\Implemented Categories\{7DD95802-9882-11CF-9FA9-00AA006C42C4}"
