windows api，一个窗体激活的时候给另外一个发消息

[csharp] view plain copy

using System;
using System.Windows.Forms;
using System.Runtime.InteropServices;
namespace WindowsApplication43
{
public partial class Form1 : Form
{
Form frm =null;
public Form1()
{
InitializeComponent();
this.Activated += Form_Activated;
}
const int WM_NCACTIVATE = 0x86;
const int WA_ACTIVE = 0x1;
[DllImport("user32.dll", EntryPoint = "SendMessage")]
public static extern int SendMessage(IntPtr hWnd, int wMsg, int wParam, int lParam);
private void button1_Click(object sender, EventArgs e)
{
frm = new Form();
frm.Text = "jinjazz";
frm.Activated += Form_Activated;
frm.Show();
frm.Location = new System.Drawing.Point(this.Left + this.Width, this.Top);
SendMessage(this.Handle, WM_NCACTIVATE, WA_ACTIVE, 0);
}
void Form_Activated(object sender, EventArgs e)
{
SendMessage(this.Handle, WM_NCACTIVATE, WA_ACTIVE, 0);
if (frm != null)
SendMessage(frm.Handle, WM_NCACTIVATE, WA_ACTIVE, 0);
}
}
}
