一、API中的MessageboxTimeout
[DllImport("user32.dll")]
public static extern int MessageBoxTimeoutA(IntPtr hWnd, string msg, string Caption, int type, int DWORD, int time);
调用:
MessageBoxTimeoutA(this.Handle,"11","aa",64,1,2000);
二、自定义类
class msg
{
private string _caption;
public void Show(int timeout, string text, string caption, MessageBoxButtons buttons, MessageBoxIcon icon)
{
this._caption = caption;
StartTimer(timeout);
MessageBox.Show(text, caption, buttons, icon);
}
private void StartTimer(int interval)
{
Timer timer = new Timer();
timer.Interval = interval;
timer.Tick += new EventHandler(Timer_Tick);
timer.Enabled = true;
}
private void Timer_Tick(object sender, EventArgs e)
{
KillMessageBox();
//停止计时器
((Timer)sender).Enabled = false;
}
[DllImport("User32.dll", EntryPoint = "FindWindow", CharSet = CharSet.Auto)]
private extern static IntPtr FindWindow(string lpClassName, string lpWindowName);
[DllImport("User32.dll", CharSet = CharSet.Auto)]
public static extern int PostMessage(IntPtr hWnd, int msg, IntPtr wParam, IntPtr lParam);
public const int WM_CLOSE = 0x10;
private void KillMessageBox()
{
//查找MessageBox的弹出窗口,注意对应标题
IntPtr ptr = FindWindow(null, this._caption);
if (ptr != IntPtr.Zero)
{
//查找到窗口则关闭
PostMessage(ptr, WM_CLOSE, IntPtr.Zero, IntPtr.Zero);
}
}
}
调用:
msg m= new msg();
m.Show(2000,"内容","标题",MessageBoxButtons.OK,MessageBoxIcon.Asterisk);
