Question

我创建了win32应用程序，我想附加一个ActiveX，所以我继续这样做

#include "stdafx.h"
#include "test.h"
#include <Windows.h>
#include <iostream>
#include <exdisp.h>



#using <System.dll>
using namespace std;
using namespace System;

// Constants

namespace {
   TCHAR * windowClassName = TEXT("win32host");
   TCHAR * windowTitle     = TEXT("Win32 interface");
   int          windowWidth     = 600;
   int          windowHeight    = 600;
}

    HWND container;

LRESULT CALLBACK WindowProc( HWND hWnd, UINT messg, WPARAM wParam, LPARAM lParam )
{
switch(messg)
{
case WM_SIZE:
// Redimensionnement du conteneur quand la taille de la fenêtre change:
MoveWindow(container,0,0,LOWORD(lParam), HIWORD(lParam),1);
break;
case WM_CLOSE:
// Détruire la fenêtre principale:
DestroyWindow(hWnd);
break;
case WM_DESTROY:
// Envoyer le message de sortie du programme:
PostQuitMessage( 0 );
break;
default:
//Retour:
return( DefWindowProc( hWnd, messg, wParam, lParam ) );
}
return 0;
}

int CALLBACK WinMain(
   HINSTANCE hInstance,
   HINSTANCE hPrevInstance,
   LPSTR lpCmdLine,
   int nCmdShow)
{

   // Register our Window class
   WNDCLASS wndclass;
   wndclass.style = CS_VREDRAW | CS_HREDRAW;
   wndclass.lpfnWndProc = &WindowProc;
   wndclass.cbClsExtra = 0;
   wndclass.cbWndExtra = 0;
   wndclass.hInstance = hInstance;
   wndclass.hIcon = NULL;
   wndclass.hCursor = NULL;
   wndclass.hbrBackground = reinterpret_cast <HBRUSH> (COLOR_BTNFACE + 1);
   wndclass.lpszMenuName = NULL;
   wndclass.lpszClassName =windowClassName;
   ::RegisterClass(&wndclass);

   // Create our main, raw win32 API window
   // We create the window invisible (meaning that we do not provide WS_VISIBLE as the window style parameter), because making it visible and then
   // adding a HwndSource will make it flicker.
   HWND mainWindow = ::CreateWindow(
      windowClassName,
      windowTitle,
      0,
      CW_USEDEFAULT,
      CW_USEDEFAULT,
      windowWidth,
      windowHeight,
      NULL,
      NULL,
      hInstance,
      0);
   ::ShowWindow (mainWindow, nCmdShow);
   ::UpdateWindow( mainWindow );

//ocx

    typedef HRESULT (WINAPI *PFonc)(IUnknown*, HWND,IUnknown**);   
    HINSTANCE hDLL2 = ::LoadLibrary(TEXT("atl.dll"));   
    if (!hDLL2) 
      return 1;   
    //PAttachControl AtlAxAttachControl = (PAttachControl) GetProcAddress(hDLL2, (LPCSTR)"AtlAxAttachControl");
    PFonc AtlAxAttachControl = (PFonc) ::GetProcAddress(hDLL2,"AtlAxAttachControl");
    CLSID clsid = GetClsid();
    IID DIID__DLiveX = GetDIID__DLiveX();
    RECT rect;
    ::GetClientRect(mainWindow,&rect);

    container = ::CreateWindowEx(WS_EX_CLIENTEDGE, L"EDIT",L"",WS_CHILD | WS_VISIBLE,100,100,rect.right,rect.bottom,mainWindow,0,hInstance,0);

    HRESULT hr = ::CoInitialize(0);


IWebBrowser2 *pIwb;
IUnknown*       unkn;
hr = ::CoCreateInstance(CLSID_WebBrowser,0,CLSCTX_ALL,IID_IWebBrowser2,(void**)&pIwb);
hr = AtlAxAttachControl(pIwb,container,0);
     if(FAILED(hr)){
         MessageBox(0, L"FAILED(AtlAxAttachControl(pitd, container, NULL))", L"Error", MB_ICONERROR | MB_OK);
    }
     pIwb->GoHome();
     pIwb->Navigate2((VARIANT*)L"www.google.com",0,0,0,0);

   // Start message processing
   ::MSG message;
   while (::GetMessageA(&message, 0, 0, 0)) {
      switch (message.message) {
      case WM_QUIT:
         break;
      default:
         ::TranslateMessage(& message);
         ::DispatchMessage(& message);
         break;
      }
   }
   CoUninitialize();
   FreeLibrary(hDLL2);
   return 0;
}

但是当我执行我的程序时，我有两个窗口，一个我的原始空，而另一个风中的Activex，

感谢。

我做了一些小改动，它编译并只显示一个包含ActiveX的窗口：

#include "stdafx.h"
#include <iostream>
#include <windows.h>
#include <comdef.h>
#include <exdisp.h>
#include <oledlg.h>

using namespace std;

// Constants

namespace {
   TCHAR * windowClassName = TEXT("win32host");
   TCHAR * windowTitle     = TEXT("Win32 interface");
   int          windowWidth     = 600;
   int          windowHeight    = 600;
}

    HWND container;

LRESULT CALLBACK WindowProc( HWND hWnd, UINT messg, WPARAM wParam, LPARAM lParam )
{
    switch(messg)
    {
        case WM_SIZE:
        // Redimensionnement du conteneur quand la taille de la fenêtre change:
        MoveWindow(container,0,0,LOWORD(lParam), HIWORD(lParam),1);
        break;
        case WM_CLOSE:
        // Détruire la fenêtre principale:
        DestroyWindow(hWnd);
        break;
        case WM_DESTROY:
        // Envoyer le message de sortie du programme:
        PostQuitMessage( 0 );
        break;
        default:
        //Retour:
        return( DefWindowProc( hWnd, messg, wParam, lParam ) );
    }
    return 0;
}

int CALLBACK WinMain(
   HINSTANCE hInstance,
   HINSTANCE hPrevInstance,
   LPSTR lpCmdLine,
   int nCmdShow)
{

   // Register our Window class
   WNDCLASS wndclass;
   wndclass.style = CS_VREDRAW | CS_HREDRAW;
   wndclass.lpfnWndProc = &WindowProc;
   wndclass.cbClsExtra = 0;
   wndclass.cbWndExtra = 0;
   wndclass.hInstance = hInstance;
   wndclass.hIcon = NULL;
   wndclass.hCursor = NULL;
   wndclass.hbrBackground = reinterpret_cast <HBRUSH> (COLOR_BTNFACE + 1);
   wndclass.lpszMenuName = NULL;
   wndclass.lpszClassName =windowClassName;
   ::RegisterClass(&wndclass);

   // Create our main, raw win32 API window
   // We create the window invisible (meaning that we do not provide WS_VISIBLE as the window style parameter), because making it visible and then
   // adding a HwndSource will make it flicker.
   HWND mainWindow = ::CreateWindow(
      windowClassName,
      windowTitle,
      0,
      CW_USEDEFAULT,
      CW_USEDEFAULT,
      windowWidth,
      windowHeight,
      NULL,
      NULL,
      hInstance,
      0);
   ::ShowWindow (mainWindow, nCmdShow);
   ::UpdateWindow( mainWindow );

    typedef HRESULT (WINAPI *PFonc)(IUnknown*, HWND,IUnknown**);   
    HINSTANCE hDLL2 = ::LoadLibrary(TEXT("atl.dll"));   
    if (!hDLL2) 
      return 1;   

    PFonc AtlAxAttachControl = (PFonc) ::GetProcAddress(hDLL2,"AtlAxAttachControl");

    RECT rect;
    ::GetClientRect(mainWindow,&rect);

    container = ::CreateWindowEx(
        WS_EX_CLIENTEDGE, 
        L"EDIT",
        L"",WS_CHILD | WS_VISIBLE,
        0,
        0,
        rect.right,
        rect.bottom,
        mainWindow,
        0,
        hInstance,
        0);

    HRESULT hr = ::CoInitialize(0);


    IWebBrowser2 *pIwb;
    hr = ::CoCreateInstance(CLSID_WebBrowser,0,CLSCTX_ALL,IID_IWebBrowser2,(void**)&pIwb);
    hr = AtlAxAttachControl(pIwb,container,0);

    if(FAILED(hr))
    {
         MessageBox(0, L"FAILED(AtlAxAttachControl(pitd, container, NULL))", L"Error", MB_ICONERROR | MB_OK);
    }
     pIwb->GoHome();
     pIwb->Navigate2((VARIANT*)L"www.google.com",0,0,0,0);

   // Start message processing
   ::MSG message;
   while (::GetMessageA(&message, 0, 0, 0))
   {
      switch (message.message) {
      case WM_QUIT:
         break;
      default:
         ::TranslateMessage(& message);
         ::DispatchMessage(& message);
         break;
      }
   }

   CoUninitialize();
   FreeLibrary(hDLL2);
   return 0;
}

Answer 2

我测试了duDE的代码，但它没有浏览到请求的URL。

我很惊讶ocx可以在没有ATL / MFC的win32中以这种方式轻松使用，但它确实有效。

我认为浏览失败的原因是：

     pIwb->Navigate2((VARIANT*)L"www.google.com",0,0,0,0);

将其更改为：

// create variant for url
VARIANT varUrl;
// init variant
VariantInit(&varUrl);
varUrl.vt = VT_BSTR;
varUrl.bstrVal = SysAllocString(L"www.google.com");
// browse to url
hr = pIwb->Navigate2((VARIANT*)&varUrl,0,0,0,0);
// release variant
VariantClear(&varUrl);

将ActiveX附加到win32应用程序中
