Passing Unmanaged object reference to Unmanaged method in C++/CLI managed method

I am getting exception when i am trying to pass unmanaged object, to COM method in method written in managed C++/CLI class. Following is the code sample

//C++/CLI class 
public ref class PSIAAdaptorManagedWrapper
{
    CConfiguration *Configuration;
    void InitializeConfig();    
}

//C++/CLI Method implementation 
void PSIAAdaptorManagedWrapper::InitializeConfig() {
    Configuration = new CConfiguration();
    Configuration->IPAddress = "127.0.0.1";
    Configuration->UserName = "User";
    Configuration->password = "password";    
    SomeComObject->GetInitiConfig((void *) Configuration);  // Exception line
}

//signature of COM object from IDL file (observer parame开发者_如何学Gor it takes is in) 
[helpstring("method InitializeCameraConfig")]
HRESULT GetInitiConfig([in] void *configparam);

Above code compiles fine. But when execute I get "System.AccessViolation" runt time error on line. I think it is because, I am trying to allocate unmanaged memory in managed function. But I am not sure how to get around this.

It could be possible that a user name or password are incorrect. AccessViolation is best noted for those issues. Also, I dont see why anything should go wrong the way you are handling things in your code above.
