使用COM简单操作IE

主要使用IWebBrowser接口。​

代码如下：

 

#include <Windows.h>
#include <ExDisp.h>
#include <assert.h>
#include <iostream>
using namespace std;

int main()
{
  HRESULT hr;
  IWebBrowser2 *pWebBrowser2 = NULL;

  OleInitialize(NULL);


  hr = CoCreateInstance(CLSID_InternetExplorer,NULL, CLSCTX_LOCAL_SERVER,
    IID_IWebBrowser2, (void**)&pWebBrowser2);
  assert(SUCCEEDED(hr));

  VARIANT vEmpty;
  VariantInit(&vEmpty);
  BSTR bstrURL = SysAllocString(L"http://www.baidu.cn");
  hr = pWebBrowser2->Navigate(bstrURL, &vEmpty, &vEmpty, &vEmpty, &vEmpty);
  if (SUCCEEDED(hr))
  {
    pWebBrowser2->put_Visible(VARIANT_TRUE);
    //pWebBrowser2->put_FullScreen(VARIANT_TRUE);
    //pWebBrowser2->put_Width(200);
    Sleep(3000);
    pWebBrowser2->Refresh();
    pWebBrowser2->GoHome();

  }
  else
  {
    pWebBrowser2->Quit();
  }
  SysFreeString(bstrURL);
  pWebBrowser2->Release();

  OleUninitialize();
  return 0;
}
