EM_SETTEXT → WM_SETTEXT の間違いです。m(_ _)m
以下サンプル：
using System;
using System.Diagnostics;
using System.Runtime.InteropServices;
using System.Windows.Forms;
namespace WindowsFormsApplication1
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
this.textBox1.Text = "FirstIndex^SecondIndex\r\n";
}
[DllImport("user32", CharSet = CharSet.Unicode)]
static extern IntPtr FindWindowEx(IntPtr hWnd, IntPtr hwndChildAfter, string lpszClass, string lpszWindow);
private void button1_Click(object sender, EventArgs e)
{
var message = this.textBox1.Text;
foreach (var p in Process.GetProcessesByName("notepad"))
{
var h = FindWindowEx(p.MainWindowHandle, IntPtr.Zero, "Edit", null);
if (h != IntPtr.Zero)
{
Sample.SetText(h, message);
//Sample.AppendText(h, message);
}
}
}
public static class Sample
{
[DllImport("user32", CharSet = CharSet.Unicode)]
static extern IntPtr SendMessage(IntPtr hWnd, int Msg, IntPtr wParam, string lParam);
[DllImport("user32", CharSet = CharSet.Unicode)]
static extern IntPtr SendMessage(IntPtr hWnd, int Msg, IntPtr wParam, IntPtr lParam);
public static void SetText(IntPtr hwnd, string text)
{
const int WM_SETEXT = 0xC;
if (text == null) text = "";
SendMessage(hwnd, WM_SETEXT, IntPtr.Zero, text);
}
public static void AppendText(IntPtr hwnd, string text)
{
const int WM_GETTEXTLENGTH = 0xE;
const int EM_SETSEL = 0xB1;
const int EM_REPLACESEL = 0xC2;
if (text == null) text = "";
IntPtr textLength = SendMessage(hwnd, WM_GETTEXTLENGTH, IntPtr.Zero, IntPtr.Zero);
SendMessage(hwnd, EM_SETSEL, textLength, textLength);
SendMessage(hwnd, EM_REPLACESEL, IntPtr.Zero, text);
}
}
}
}
