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 windowsprivate 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
