return value CoCreateInstance not documented in MSDN

Hello everyone,


The return value of CoCreateInstance is -2146232576, which is un-documented in MSDN.

http://msdn2.microsoft.com/en-us/library/ms686615.aspx

What does it mean? What is wrong with my code?

Code:

HRESULT hr = CoCreateInstance(CLSID_MyDriver,
			NULL,
			CLSCTX_INPROC_SERVER,
			IID_IMyDriver,
			reinterpret_cast<void**>(&driver_interface));

if (FAILED(hr))
{
	if (hr == REGDB_E_CLASSNOTREG)
	{
		printf("Couldn't create the instance!... 0x%x\n", hr);
	}
	else if (hr == CLASS_E_NOAGGREGATION)
	{
		printf("Couldn't create the instance!... 0x%x\n", hr);
	}
	else if (hr == E_NOINTERFACE)
	{
		printf("Couldn't create the instance!... 0x%x\n", hr);
	}
	else if (hr == S_OK)
	{
		printf("Couldn't create the instance!... 0x%x\n", hr);
	}
	else
	{
		printf("Couldn't create the instance!... 0x%x\n", hr);
	}
}

thanks in advance,
George

Convert that to hex: 0x80131700 Then Google it.

It seems to be something .NET related. It's an undocumented error code alright. In fact I can't find any error text description or error code name anywhere. I don't see any threads that give any answers other than make sure you are using an administrator account, and reinstalling .NET.

I don't think MS want us to know what that error code means.
