问题描述

今天写代码给360安全浏览器窗口发消WM_CLOSE息竟然它不睬我，想问问大神怎么回事？

想想这种情况应该是不可能的，浏览器在windows系统下运作可以不听操作系统的命令？怎么可能，只可能我获得的东西不正确

void CtestDlg::OnBnClickedButton1()
{
// TODO: Add your control notification handler code here
STARTUPINFO suInfo;
PROCESS_INFORMATION procInfo;

memset (&suInfo, 0, sizeof(suInfo));
suInfo.cb = sizeof(suInfo);
suInfo.dwFlags = STARTF_USESHOWWINDOW;
suInfo.wShowWindow = TRUE;
CHAR chCmdLine[] = " http://www.baidu.com/";

HKEY key = NULL;
CHAR szXplorer[MAX_PATH];
DWORD dwBufLen;
DWORD type = REG_SZ;

ZeroMemory(szXplorer,MAX_PATH);

if(ERROR_SUCCESS == ::RegOpenKeyEx(HKEY_CLASSES_ROOT,
    "http\shell\open\command",
    0,
    KEY_QUERY_VALUE,
    &key))
{
    LONG lRet;
    lRet = ::RegQueryValueEx(key,NULL,NULL,&type,(LPBYTE)szXplorer,&dwBufLen);
    if(lRet == ERROR_SUCCESS)
        strcat(szXplorer, chCmdLine);
    RegCloseKey(key);
}

BOOL bRet = CreateProcess(NULL/*"C://Program Files//360Chrome//Chrome//Application//360chrome.exe"*//*"c://program files//internet explorer//iexplore.exe"*/,
    szXplorer, NULL, NULL, false,
    NORMAL_PRIORITY_CLASS, NULL, NULL, &suInfo, &procInfo);
if(bRet)
{
    CloseHandle(procInfo.hThread);
    CloseHandle(procInfo.hProcess);
}

m_dwProcessId = procInfo.dwProcessId;

}

void CtestDlg::OnBnClickedButton2()
{
// TODO: Add your control notification handler code here
HANDLE handle = OpenProcess(SYNCHRONIZE | PROCESS_TERMINATE, FALSE, m_dwProcessId);
EnumWindows(EnumWindowsProc, m_dwProcessId);
CloseHandle(handle);
}

BOOL CALLBACK CtestDlg::EnumWindowsProc(HWND hwnd, LPARAM lParam)
{
DWORD wndPid;
CString Title;
// lParam = procInfo.dwProcessId;

// This gets the windows handle and pid of enumerated window.
GetWindowThreadProcessId(hwnd, &wndPid);

// This gets the windows title text
// from the window, using the window handle
CWnd::FromHandle( hwnd )->GetWindowText(Title);

//  this makes sure that the PID matches that PID we started, and window
// text exists, before we kill it . I don't think this is really needed,
// I included it because some apps have more than one window.
if ( wndPid == (DWORD)lParam && Title.GetLength() != 0)
{
    //  Please kindly close this process
    ::PostMessage(hwnd, WM_CLOSE, 0, 0);
    return false;
}
else
{
    // Keep enumerating
    return true;
}

}

解决方案

是不是没取对句柄？用spy++看看。或者试试其他几个关闭的消息WM_DESTROY ，WM_CLOSE，WM_QUIT。或者发送鼠标点击消息，参数传关闭按钮的坐标。

解决方案二：

它如果能轻易发一个消息就关了，那才是奇怪的事情。

解决方案三：

几种可能：
1. 360应该是没有处理的WM_CLOSE消息，它不允许你这么发送消息来关闭它。
2. 你的消息没有发送给正确的窗口

解决方案四：

你的系统上也安装了360安全卫士吗，如果安装了可能会有影响。

360可能挂住了 sendmessage或者postmessage函数。

另外，你测试过 GetWindowThreadProcessId(hwnd, &wndPid) 值返回的是360安全浏览器的进程id不，和任务管理器里的比较一下
