避免click事件，而面板刷新

Question

我在馬形成兩個面板。 panel1在button1上放置位置let x：10，y：10和panel2，其位置x：10，y：10。

究竟Button1的事： - 它隱藏PANEL1並顯示是Panel2在同一位置。

但每當我完成它的過程後兩次Button1的點擊觸發按鈕2單擊事件，

plz幫助我儘快

希望下面的鏈接將證明我的概率顯然

代碼到目前爲止

void hidepanel() 
{ 
    panel1.Visible = false; 
    panel2.Visible = false; 
} 

private void Form1_Load(object sender, EventArgs e) 
{ 
    hidepanel(); 
    panel1.Visible = true; 
    panel2.Location = new Point(262,19); 
    panel1.Location = new Point(0, 0); 
} 

private void button1_Click(object sender, EventArgs e) 
{ 
    hidepanel(); 
    panel2.Location = new Point(0, 0); 
    panel2.Visible = true; 
} 

private void button2_Click(object sender, EventArgs e) 
{ 
    MessageBox.Show("2"); 
}

只是添加一些邏輯來隱藏/取消隱藏啓用/禁用oposite組件。就像這樣：

private void button1_Click(object sender, EventArgs e) 
    { 
     addLog("Button 1 clicked"); 
     button1.Enabled = false; 
     button2.Enabled = false; 
     panel1.Visible = false; 
     panel2.Visible = true; 
     button2.Enabled = true; 
    } 

    private void button2_Click(object sender, EventArgs e) 
    { 
     addLog("Button 2 clicked"); 
     button2.Enabled = false; 
     panel2.Visible = false; 
     panel1.Visible = true; 
     button1.Enabled = true; 

    } 

作品對我來說像一個風情萬種：

編輯： 現在，我看到了問題，鼠標點擊被排入窗口消息隊列，並且會點擊按鈕2上的點擊事件在禁用/隱藏的按鈕上1。

我發現這裏的解決方案：Ignoring queued mouse events

，並改變了代碼：

 public static void ClearMouseClickQueue() 
    { 
     win32msg.NativeMessage message; 
     while (win32msg.PeekMessage(out message, IntPtr.Zero, (uint)win32msg.WM.WM_MOUSEFIRST, (uint)win32msg.WM.WM_MOUSELAST, 1)) 
     { 
     } 
    } 
    ... 
      private void button1_Click_1(object sender, EventArgs e) 
    { 
     addLog("Button 1 clicked"); 
     button1.Enabled = false; 
     button2.Enabled = false; 
     panel1.Visible = false; 
     System.Threading.Thread.Sleep(2000); 
     ClearMouseClickQueue(); 
     panel2.Visible = true; 
     button2.Enabled = true; 
    } 

其中的PeekMessage等定義另一個類：

using System; 

    using System.Collections.Generic; 
    using System.Text; 

    using System.Runtime.InteropServices; 

    namespace PanelTest 
    { 
     public static class win32msg 
     { 
      [DllImport("coredll.dll")] 
      [return: MarshalAs(UnmanagedType.Bool)] 
      public static extern bool PeekMessage(out NativeMessage lpMsg, IntPtr hWnd, uint wMsgFilterMin, uint wMsgFilterMax, uint wRemoveMsg); 

      public enum WM : uint{ 
       /// <summary> 
       /// Use WM_MOUSEFIRST to specify the first mouse message. Use the PeekMessage() Function. 
       /// </summary> 
       WM_MOUSEFIRST = 0x0200, 
       /// <summary> 
       /// Use WM_MOUSELAST to specify the last mouse message. Used with PeekMessage() Function. 
       /// </summary> 
       WM_MOUSELAST = 0x020E, 
      } 
      [StructLayout(LayoutKind.Sequential)] 
      public struct NativeMessage 
      { 
       public IntPtr handle; 
       public uint msg; 
       public IntPtr wParam; 
       public IntPtr lParam; 
       public uint time; 
       public System.Drawing.Point p; 
      } 
     } 
    } 

請測試。
