Retrieving a Variable from a Built-in Object

The following example demonstrates how to retrieve the value of variable stored in the Session object.

STDMETHODIMP CHowtos1::OnStartPage (IUnknown* pUnk)  
{
  HRESULT hr;  
  IScriptingContext *piContext;
  
  //Get IScriptingContext Interface
  hr = pUnk->QueryInterface(IID_IScriptingContext, (void**)&piContext);

  //Get Response Object Pointer
  IResponse* piResponse = NULL;
  hr = piContext->get_Response(&piResponse);

  //Create a VARIANT to receive the Session Variable's Value 
  VARIANT vtOut;
  VariantInit(&vtOut);

  //Get Session Object Pointer
  ISessionObject *piSession = NULL;
  hr = piContext->get_Session(&piSession);
  
  //Get the Value for Session Variable "Var1"
  hr = piSession->get_Value(OLESTR("Var1"), &vtOut);

  //Write the value of Var1 to the HTML page
  piResponse->Write(vtOut);

  //Release Interface Pointers
  piSession->Release();  
  piResponse->Release();
  piContext->Release();

  return S_OK;
}
