Plugins_Wrapper

If you plan to create a wrapper or an external tool to read the dll, here is an example with a plugin created with IID_IVdjPluginBasic8

HRESULT LoadDLL(TCHAR *strFileName)
{
HRESULT hr;
HMODULE hDLL;
typedef HRESULT (VDJ_API *dllGetClassObjectType)(IN REFCLSID rclsid, IN REFIID riid, OUT LPVOID FAR* ppv); 
IVdjPlugin8 *pClf;
TVdjPluginInfo8 info8; 

hDLL = LoadLibrary(strFileName);
if( hDLL == NULL ) return S_FALSE;

dllGetClassObjectType dllGetClassObject1 = (dllGetClassObjectType) GetProcAddress(hDLL,"_DllGetClassObject@12");   
	if( dllGetClassObject1 == NULL ) 
	{
		FreeLibrary(hDLL);
		return S_FALSE;
	}

	hr = dllGetClassObject1(CLSID_VdjPlugin8, IID_IVdjPluginBasic8, (void**) &pClf);   // find, create and get the class defned in the VirtualDJ plugin
	if(hr==CLASS_E_CLASSNOTAVAILABLE)
	{		
		FreeLibrary(hDLL);
                 return S_FALSE;
	}

	if(hr==NO_ERROR) 
	{
               pClf->hInstance = ....; // give a HINSTANCE to the VirtualDJ plugin

              hr = pClf->OnGetPluginInfo(&info8);  // get the info from the VirtualDJ plugin

               pClf->Release();

             FreeLibrary(hDLL);
	      return S_OK;
}
}
