我有兴趣为开源密码管理员
Keepass开发一个插件.现在,Keepass目前根据窗口标题检测到什么密码复制/粘贴.这样可以防止Keepass从当前网站(例如Chrome)中不会主动更新其窗口标题的应用程序检测到您需要的当前密码.
我如何通过另一个进程窗口元素(按钮,标签,文本框)与Spy的工作方式类似？当您运行间谍时,您可以将鼠标悬停在其他程序窗口上,并获取有关各种控件(标签,文本框等)的各种属性的各种信息.理想情况下,我想让我的Keepass插件通过浏览活动窗口的元素来增强当前的窗口检测,以找到匹配的帐户来复制/粘贴密码.
如何使用其他进程窗口元素,并可以使用C#检索标签和文本框值？
解决方法
我正在回答类似的问题：
How can I detect if a thread has windows handles?.像它所说,主要的想法是通过进程窗口和他们的子窗口枚举使用
EnumWindows和
EnumChildWindows API调用来获取窗口句柄,然后使用WM_GETTEXT调用GetwindowText或SendDlgitemmessage来获取窗口文字.我修改了代码,做出一个应该做你所需要的例子(对不起,有点长:) :)它遍历进程和他们的窗口并将窗口文本转储到控制台中.
static void Main(string[] args)
{
foreach (Process procesInfo in Process.GetProcesses())
{
Console.WriteLine("process {0} {1:x}",procesInfo.ProcessName,procesInfo.Id);
foreach (Processthread threadInfo in procesInfo.Threads)
{
// uncomment to dump thread handles
//Console.WriteLine("\tthread {0:x}",threadInfo.Id);
IntPtr[] windows = GetwindowHandlesForThread(threadInfo.Id);
if (windows != null && windows.Length > 0)
foreach (IntPtr hWnd in windows)
Console.WriteLine("\twindow {0:x} text:{1} caption:{2}",hWnd.ToInt32(),GetText(hWnd),GetEditText(hWnd));
}
}
Console.ReadLine();
}
private static IntPtr[] GetwindowHandlesForThread(int threadHandle)
{
_results.Clear();
EnumWindows(WindowEnum,threadHandle);
return _results.ToArray();
}
// enum windows
private delegate int EnumWindowsProc(IntPtr hwnd,int lParam);
[DllImport("user32.Dll")]
private static extern int EnumWindows(EnumWindowsProc x,int y);
[DllImport("user32")]
private static extern bool EnumChildWindows(IntPtr window,EnumWindowsProc callback,int lParam);
[DllImport("user32.dll")]
public static extern int GetwindowThreadProcessId(IntPtr handle,out int processId);
private static List<IntPtr> _results = new List<IntPtr>();
private static int WindowEnum(IntPtr hWnd,int lParam)
{
int processID = 0;
int threadID = GetwindowThreadProcessId(hWnd,out processID);
if (threadID == lParam)
{
_results.Add(hWnd);
EnumChildWindows(hWnd,WindowEnum,threadID);
}
return 1;
}
// get window text
[DllImport("user32.dll",CharSet = CharSet.Auto,SetLastError = true)]
static extern int GetwindowText(IntPtr hWnd,StringBuilder lpString,int nMaxCount);
[DllImport("user32.dll",SetLastError = true,CharSet = CharSet.Auto)]
static extern int GetwindowTextLength(IntPtr hWnd);
private static string GetText(IntPtr hWnd)
{
int length = GetwindowTextLength(hWnd);
StringBuilder sb = new StringBuilder(length + 1);
GetwindowText(hWnd,sb,sb.Capacity);
return sb.ToString();
}
// get richedit text
public const int GWL_ID = -12;
public const int WM_GETTEXT = 0x000D;
[DllImport("User32.dll")]
public static extern int getwindowlong(IntPtr hWnd,int index);
[DllImport("User32.dll")]
public static extern IntPtr SendDlgitemmessage(IntPtr hWnd,int IDDlgitem,int uMsg,int nMaxCount,StringBuilder lpString);
[DllImport("User32.dll")]
public static extern IntPtr GetParent(IntPtr hWnd);
private static StringBuilder GetEditText(IntPtr hWnd)
{
Int32 dwID = getwindowlong(hWnd,GWL_ID);
IntPtr hWndParent = GetParent(hWnd);
StringBuilder title = new StringBuilder(128);
SendDlgitemmessage(hWndParent,dwID,WM_GETTEXT,128,title);
return title;
}
希望这有帮助,问候
