vs2005 c++ MFC IE8 新增變數 指令碼錯誤 此網站的某個載入項執行失敗
今天在做C++ MFC，給對話方塊中控制元件Edit Control新增變數時，出現一個指令碼錯誤，“此網站的某個載入項執行失敗..."，這個錯誤可夠莫名其妙的，網上查閱了一些資料發現問題所在，原因是我前幾天為了除錯javascript，更新了IE到IE8（IE8可以斷點除錯javascript）,IE8增加了安全級別，當MFC在新增變數時會執行IInternetSecurityManager 介面，IE8阻止其執行。解決方法是：在登錄檔中開放1207策略，如果是vs2005，則需要重新安裝sp1補丁，vs2008不需要。以下是英文參考資料：
Some VS2005 and VS2008 Wizards Pop Up Script Error.
Visual C++ team has discovered that after installing the current release of Internet Explorer (Internet Explorer 8), some VC++ wizards do not function correctly. The products affected are Visual Studio 2005 and Visual Studio 2008. Following are the affected wizards:
- Add Function
- Add Variable
- Smart Device – New Project Creation
- Smart Device – Add Class
Invoking any of the above wizards in VS2005 or VS2008 will pop up a script error if IE8 is installed on the machine. We have a workaround for those who have encountered this error.
Please follow the following steps:
- Open regedit (on a 64-bit OS, open the 32-bit regedit)
- Under “HKEY_CURRENT_USER/Software/Microsoft/Windows/CurrentVersion/Internet
Settings/Zones”, create a new key called 1000 (if it isn't already there)
- Under 1000, create a DWORD entry with:
o Name = 1207
o Type = REG_DWORD
o Data = 0x000000
For the workaround to work on VS2005 however, the VS2005 SP1 (and VS2005 SP1 Update for Windows Vista) has to be installed.
Following is a brief explanation of the problem and the workaround:
The VC++ Wizards Engine implements the IInternetSecurityManager interface. In this implementation it allows or disallows specific actions under certain policies that Internet Explorer queries it about. In IE8 a custom Security Manager now also gets queried about the URLACTION_ACTIVEX_OVERRIDE_REPURPOSEDETECTION policy which IE previously did not delegate to custom security managers when the engine wasn’t running in the iexplore.exe process. The IE engine then fails this action because we don’t have a policy entry for it in the custom zone for VC++ Wizards. We are still investigating whether this change in IE8 is by design and will possibly be addressing it by a fix in either the Wizard or IE components depending on the outcome.
The above workaround lets the policy 1207 (URLACTION_ACTIVEX_OVERRIDE_REPURPOSEDETECTION) to be allowed in zone 1000 (custom zone of VC++ Wizards engine). This allows the wizard code to work as intended.
We apologize for the inconvenience this issue may have caused you.
Thank you
