Hi I faced this Interoperability problem if any one have answers let
me know about it.

I developed the COM interface in VC++ as follows :


	interface IModuleConfig
	{
		HRESULT SetValue(GUID guid, VARIANT* var);
	}

	class CModuleConfig : public IModuleConfig
	{
	};

HRESULT CModuleConfig :: SetValue(GUID guid, VARIANT* var)
{

	if(var.vt == VT_BOOL)
	{
		m_bFound = var->boolVal;
	}

	return S_OK;
}




I converted it into aC# as follows :

	[ComImport,Guid["Guid of IModuleConfig :"]
	public interface IModuleConfig
	{
		int SetValue(Guid guid,Object obj);
	}


	m_pConfig = Activator.CreateInstance(CModuleConfig);
	IModuleConfig m_pModuleConfig = m_pConfig as IModuleConfig;

	m_pModuleConfig.SetValue( guid,true);

	The "true" value is not properly send to the COM component Any one
have an idea about it ?...

Try it like this

void SetValue(Guid guid, ref Object obj);
