我试图让这件事整天都在工作。 我试图将输入文本粘贴到另一个Windows应用程序的文本框中(比如Chrome的URL栏) 我设法得到主窗口hwnd,但是当我使用SendMessage时,它只是改变了窗口的标题
所以我想弄清楚我是如何动态地找到文本框的hwnd。 我也试过Spy ++,但由于某些原因,它给了我所有子窗口的相同hwnd,必须做错了。
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);
}
}

我也试过Spy ++,但它给了我所有子窗口的相同hwnd 出于某种原因,必须做错事。
并非所有应用程序都使用由Windows句柄支持的旧式“重型”控件。例如,.Net WPF应用程序将仅显示主窗口本身的一个句柄的相同行为。根据需要,DirectX可以直接将所有内容绘制到屏幕上。 Web浏览器也很“轻”,不使用句柄支持的控件。基本上,如果Spy ++没有在主窗口中显示子窗口,那么您将无法使用传统的窗口操作API或SendMessage()。

可悲的是,我找不到按照我想要的方式制作它的方法,但我找到了一个非常有效的解决方法:
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", ExactSpelling = true, CharSet = CharSet.Auto)]
[return: MarshalAs(UnmanagedType.Bool)]
private static extern bool SetForegroundWindow(IntPtr hWnd);
[DllImport("user32.dll", SetLastError = true)]
private static extern IntPtr FindWindow(string lpClassName, string lpWindowName);
static void Main(string[] args)
{
IntPtr hWnd = FindWindow(null, "Origin");
if (!hWnd.Equals(IntPtr.Zero))
{
// activate Notepad window
if (SetForegroundWindow(hWnd))
{
// send "Hello World!"
SendKeys.SendWait("Hello World!");
// send key "Tab"
SendKeys.SendWait("{TAB}");
// send key "Enter"
SendKeys.SendWait("{ENTER}");
}
}
}
}
}
