Syntax

FUNCTION Invoke (BYVAL errorCode AS HRESULT, BYVAL createdController AS Afx_ICoreWebView2Controller PTR) AS HRESULT

Parameters

Name		Description
`[Invoke](#invoke)`		Provides the result of the corresponding asynchronous method.
`errorCode`		[in] An HRESULT code to check for errors.
`createdController`		[in] A pointer to the ICoreWebView2Controller interface.

Description

Implementation of the ICoreWebView2CreateCoreWebView2ControllerCompletedHandler callback interface.

The controller is created during the processing of the Invoke method of the CWebView2CreateCoreWebView2EnvironmentCompletedHandlerInternal class by calloing the CreateCoreWebView2Controller of the ICoreWebView2Environment interface. A pointer to the ICoreWebView2Controller interface is provided by WebViewin the Invoke method of the CWebView2CreateCoreWebView2ControllerCompletedHandlerInternal class.

Examples

FUNCTION CWebView2CreateCoreWebView2EnvironmentCompletedHandlerInternal.Invoke (BYVAL errorCode AS HRESULT, BYVAL createdEnvironment AS Afx_ICoreWebView2Environment PTR) AS HRESULT CWV2_DP("") IF errorCode = S_OK AND m_pWebView2 <> NULL THEN

m_pWebView2->m_pEnv = createdEnvironment
  m_pWebView2->m_pEnv->AddRef
  ' // Create controller
  DIM pController AS CWebView2CreateCoreWebView2ControllerCompletedHandlerInternal PTR
  pController = NEW CWebView2CreateCoreWebView2ControllerCompletedHandlerInternal(m_pWebView2)
  m_pWebView2->m_pEnv->CreateCoreWebView2Controller(m_pWebView2->m_hWnd, cast(ANY PTR, pController))
  ' // Get the runtime versión
  DIM wszVersion AS LPWSTR
  IF m_pWebView2->m_pEnv->get_BrowserVersionString(@wszVersion) = S_OK THEN
     m_pWebView2->m_BrowserVersion = *wszVersion
     CoTaskMemFree(wszVersion)
