剪贴板事件C＃ [英] Clipboard event C#

问题描述

解决方案

我想你必须使用一些p / invoke：

  [DllImport（User32.dll，CharSet = CharSet.Auto）] 
 public static extern IntPtr SetClipboardViewer（IntPtr hWndNewViewer）; 
  

请参阅本文介绍如何在c＃中设置剪贴板监视器

基本上，您使用

  _ClipboardViewerNext = SetClipboardViewer（this.Handle）注册您的应用程序作为剪贴板查看器; 
  

然后您将收到 WM_DRAWCLIPBOARD 消息，您可以通过覆盖 WndProc 来处理：

  protected override void WndProc （ref Message m）
 {
 switch（（Win32.Msgs）m.Msg）
 {
 case Win32.Msgs.WM_DRAWCLIPBOARD：
 //处理剪贴板已更改
 break; 
 // ... 
} 
} 
  

（有更多的要做;沿着剪贴板链传递东西，取消注册你的视图，但是你可以从文章）

Is there a clipboard changed or updated event that i can access through C#?

解决方案

I think you'll have to use some p/invoke:

[DllImport("User32.dll", CharSet=CharSet.Auto)]
public static extern IntPtr SetClipboardViewer(IntPtr hWndNewViewer);

See this article on how to set up a clipboard monitor in c#

Basically you register your app as a clipboard viewer using

_ClipboardViewerNext = SetClipboardViewer(this.Handle);

and then you will recieve the WM_DRAWCLIPBOARD message, which you can handle by overriding WndProc:

protected override void WndProc(ref Message m)
{
    switch ((Win32.Msgs)m.Msg)
    {
        case Win32.Msgs.WM_DRAWCLIPBOARD:
        // Handle clipboard changed
        break;
        // ... 
   }
}

(There's more to be done; passing things along the clipboard chain and unregistering your view, but you can get that from the article)
