WMI引发异常“0x800706B5：接口未知。” [英] WMI raises exception "0x800706B5: The interface is unknown."

问题描述

我有一段代码可以无缝地工作到现在为止。它使用Windows Management Instrumentation API。我没有更改我的机器中的代码或任何内容（据我所知），但现在当代码在Visual Studio调试器（2008或2003）下运行时，它会引发异常，显然是在调用<$ c $时c> ConnectServer 在下面的代码中：

I have a piece of code that worked seamlessly until now. It uses the Windows Management Instrumentation API. I have not changed the code nor anything in my machine (as far as I know), but now when the code is run under the Visual Studio debugger (either 2008 or 2003), it raises an exception, apparently when calling ConnectServer in the code below:

HRESULT hRes;

// Initialize
CoInitialize(0);

// Create the locator
IWbemLocator* pIWbemLocator= NULL;
IWbemServices* pWbemServices= NULL;
hRes= CoCreateInstance(
    CLSID_WbemLocator,
    0,
    CLSCTX_INPROC_SERVER,
    IID_IWbemLocator, (LPVOID *) &pIWbemLocator);
if (hRes != S_OK)
{
    return false; // Could not create the locator
}

// Connect to the server
hRes= pIWbemLocator->ConnectServer(
    L"ROOT\\CIMV2",          // WMI namespace
    NULL,                    // User name
    NULL,                    // User password
    0,                       // Locale
    NULL,                    // Security flags
    0,                       // Authority
    0,                       // Context object
    &pWbemServices           // IWbemServices proxy
    );
if (hRes != S_OK)
{
    return false; // Could not connect to the server
}

如果我忽略异常，则会得到0xC0020043：RPC中发生内部错误。例外。



我相信代码是正确的，因为它已经使用多年了。我强调，在没有调试器的情况下执行仍然有效（发布和调试版本），所以我不能责怪我的Windows配置。但是当我想调试时我就陷入困境。



有人可以帮忙吗？

If I Ignore the exception, I then get a "0xC0020043: An internal error occurred in RPC." exception.

I am confident that the code is correct as it has been in use for years. And I stress that when executing without the debugger is still works (both Release and Debug builds), so I cannot blame my Windows configuration. But I am stuck when I want to debug.

Can anybody help ?

推荐答案

这里有一个样品。

试着让它运行。



有趣的区别是：

here is a sample.
http://msdn.microsoft.com/en-us/library/windows/desktop/aa390423(v=vs.85).aspx[^]

Try to get it running.

The interesting difference ist:

CoInitializeEx(0, COINIT_MULTITHREADED);

作为一个工作区，我已经针对这个特定的例外禁用了调试器的中断。



调试>例外......>添加> Win32异常> 输入无法找到界面和0x800706B5。然后取消选中例外。



似乎到目前为止工作，希望它在最不希望的时候不会重现......

As a workaroud, I have disabled the break into the debugger for this specific exception.

Debug > Exceptions... > Add > Win32 Exceptions > enter "The interface can not be found" and "0x800706B5". Then uncheck the exception.

Seems to work so far, hoping it will not resurface when the least desired...
