我正在努力让这个东西整天工作。 我正在尝试将输入文本粘贴到另一个 Windows 应用程序中的文本框(比如说 Chrome 的 URL 栏) 我设法获取了主窗口的hwnd,但是当我使用SendMessage时,它只是改变了窗口的标题
所以我试图弄清楚如何动态地找到我的文本框的 hwnd。 我也尝试过 Spy++,但由于某种原因它给了我所有子窗口相同的 hwnd,一定是做错了什么。
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Runtime.InteropServices;
using System.Diagnostics;
namespace ConsoleApplication1
{
class Program
{
[DllImport("User32.dll")]
public static extern int SendMessage(IntPtr hWnd, int uMsg, int wParam, string lParam);
private static IntPtr WinGetHandle(string wName)
{
IntPtr hWnd = IntPtr.Zero;
foreach (Process pList in Process.GetProcesses())
{
if (pList.MainWindowTitle.Contains(wName))
{
hWnd = pList.MainWindowHandle;
}
}
return hWnd;
}
static void Main(string[] args)
{
List<IntPtr> myList = GetChildWindows(WinGetHandle("chrome"));
foreach(IntPtr ptr in myList)
{
//No idea which one of those IntPtr is actually my textbox
//SendMessage((IntPtr)788018, 0x000C, 0, "text here");
}
Console.ReadLine();
}
[DllImport("user32")]
[return: MarshalAs(UnmanagedType.Bool)]
public static extern bool EnumChildWindows(IntPtr window, EnumWindowProc callback, IntPtr i);
public static List<IntPtr> GetChildWindows(IntPtr parent)
{
List<IntPtr> result = new List<IntPtr>();
GCHandle listHandle = GCHandle.Alloc(result);
try
{
EnumWindowProc childProc = new EnumWindowProc(EnumWindow);
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;
}
public delegate bool EnumWindowProc(IntPtr hWnd, IntPtr parameter);
}
}
最佳答案
I also tried Spy++ but it gave me the same hwnd for all child windows for some reason, must did something wrong.
并非所有应用程序都使用由 Windows 句柄支持的老式“重型”控件。例如,.Net WPF 应用程序将表现出与主窗口本身仅一个句柄相同的行为。其他所有内容都根据需要通过 DirectX 直接绘制到屏幕上。 Web 浏览器也很“轻”,不使用句柄支持的控件。基本上,如果 Spy++ 不在主窗口内显示子窗口,那么您将无法使用传统的窗口操作 API 或 SendMessage()。
