获取进程的所有窗口句柄

使用 Microsoft Spy++,我可以看到属于进程的以下窗口:

Process XYZ 窗口句柄,以树形式显示,就像 Spy++ 给我的:

A
  B
  C
     D
E
F
  G
  H
  I
  J
     K

我可以获取进程,并且 MainWindowHandle 属性指向窗口 F 的句柄。如果我使用枚举子窗口,我可以获得 G 到 K 的窗口句柄列表,但我不知道如何找到 A 到 D 的窗口句柄。如何枚举不是句柄子级的窗口由 Process 对象的 MainWindowHandle 指定?

枚举我正在使用 win32 调用:

[System.Runtime.InteropServices.DllImport(strUSER32DLL)]
            public static extern int EnumChildWindows(IntPtr hWnd, WindowCallBack pEnumWindowCallback, int iLParam);

Using Microsoft Spy++, I can see that the following windows that belong to a process:

Process XYZ window handles, displayed in tree form just like Spy++ gives me:

A
  B
  C
     D
E
F
  G
  H
  I
  J
     K

I can get the process, and the MainWindowHandle property points to the handle for window F. If I enumerate the child windows using I can get a list of window handles for G through K, but I can't figure out how to find the window handles for A through D. How can I enumerate windows that are not children of the handle specified by MainWindowHandle of the Process object?

To enumerate I'm using the win32 call:

[System.Runtime.InteropServices.DllImport(strUSER32DLL)]
            public static extern int EnumChildWindows(IntPtr hWnd, WindowCallBack pEnumWindowCallback, int iLParam);

IntPtr.Zero 作为 hWnd 传递以获取系统中的每个根窗口句柄。

然后,您可以通过调用 来检查 Windows 所有者进程GetWindowThreadProcessId

Pass IntPtr.Zero as hWnd to get every root window handle in the system.

You can then check the windows' owner process by calling GetWindowThreadProcessId.

对于仍然想知道的每个人,这就是答案:

List<IntPtr> GetRootWindowsOfProcess(int pid)
{
    List<IntPtr> rootWindows = GetChildWindows(IntPtr.Zero);
    List<IntPtr> dsProcRootWindows = new List<IntPtr>();
    foreach (IntPtr hWnd in rootWindows)
    {
        uint lpdwProcessId;
        WindowsInterop.User32.GetWindowThreadProcessId(hWnd, out lpdwProcessId);
        if (lpdwProcessId == pid)
            dsProcRootWindows.Add(hWnd);
    }
    return dsProcRootWindows;
}

public static List<IntPtr> GetChildWindows(IntPtr parent)
{
    List<IntPtr> result = new List<IntPtr>();
    GCHandle listHandle = GCHandle.Alloc(result);
    try
    {
        WindowsInterop.Win32Callback childProc = new WindowsInterop.Win32Callback(EnumWindow);
        WindowsInterop.User32.EnumChildWindows(parent, childProc, GCHandle.ToIntPtr(listHandle));
    }
    finally
    {
        if (listHandle.IsAllocated)
            listHandle.Free();
    }
    return result;
}

private static bool EnumWindow(IntPtr handle, IntPtr pointer)
{
    GCHandle gch = GCHandle.FromIntPtr(pointer);
    List<IntPtr> list = gch.Target as List<IntPtr>;
    if (list == null)
    {
        throw new InvalidCastException("GCHandle Target could not be cast as List<IntPtr>");
    }
    list.Add(handle);
    //  You can modify this to check to see if you want to cancel the operation, then return a null here
    return true;
}

for WindowsInterop:

public delegate bool Win32Callback(IntPtr hwnd, IntPtr lParam);

for WindowsInterop.User32:

[DllImport("user32.dll")]
public static extern uint GetWindowThreadProcessId(IntPtr hWnd, out uint lpdwProcessId);

[DllImport("user32.Dll")]
[return: MarshalAs(UnmanagedType.Bool)]
public static extern bool EnumChildWindows(IntPtr parentHandle, Win32Callback callback, IntPtr lParam);

现在可以通过 GetRootWindowsOfProcess 简单地获取每个根窗口,并通过 GetChildWindows 获取它们的子窗口。

For everyone still wondering, this is the answer:

List<IntPtr> GetRootWindowsOfProcess(int pid)
{
    List<IntPtr> rootWindows = GetChildWindows(IntPtr.Zero);
    List<IntPtr> dsProcRootWindows = new List<IntPtr>();
    foreach (IntPtr hWnd in rootWindows)
    {
        uint lpdwProcessId;
        WindowsInterop.User32.GetWindowThreadProcessId(hWnd, out lpdwProcessId);
        if (lpdwProcessId == pid)
            dsProcRootWindows.Add(hWnd);
    }
    return dsProcRootWindows;
}

public static List<IntPtr> GetChildWindows(IntPtr parent)
{
    List<IntPtr> result = new List<IntPtr>();
    GCHandle listHandle = GCHandle.Alloc(result);
    try
    {
        WindowsInterop.Win32Callback childProc = new WindowsInterop.Win32Callback(EnumWindow);
        WindowsInterop.User32.EnumChildWindows(parent, childProc, GCHandle.ToIntPtr(listHandle));
    }
    finally
    {
        if (listHandle.IsAllocated)
            listHandle.Free();
    }
    return result;
}

private static bool EnumWindow(IntPtr handle, IntPtr pointer)
{
    GCHandle gch = GCHandle.FromIntPtr(pointer);
    List<IntPtr> list = gch.Target as List<IntPtr>;
    if (list == null)
    {
        throw new InvalidCastException("GCHandle Target could not be cast as List<IntPtr>");
    }
    list.Add(handle);
    //  You can modify this to check to see if you want to cancel the operation, then return a null here
    return true;
}

for WindowsInterop:

public delegate bool Win32Callback(IntPtr hwnd, IntPtr lParam);

for WindowsInterop.User32:

[DllImport("user32.dll")]
public static extern uint GetWindowThreadProcessId(IntPtr hWnd, out uint lpdwProcessId);

[DllImport("user32.Dll")]
[return: MarshalAs(UnmanagedType.Bool)]
public static extern bool EnumChildWindows(IntPtr parentHandle, Win32Callback callback, IntPtr lParam);

Now one can simply get every root window by GetRootWindowsOfProcess, and their children by GetChildWindows.

您可以使用 EnumWindows 获取每个顶级窗口,然后根据 GetWindowThreadProcessId

You can use EnumWindows to get every top-level window, and then filter the results based on GetWindowThreadProcessId.
