}
[DefaultEvent("ClipboardChanged")]
public partial class ClipboardMonitor : Control
{
IntPtr nextClipboardViewer;
public ClipboardMonitor()
{
this.BackColor = Color.Red;
this.Visible = false;
nextClipboardViewer = (IntPtr)SetClipboardViewer((int)this.Handle);
}
/// <summary>
/// Clipboard contents changed.
/// </summary>
public event EventHandler<ClipboardChangedEventArgs> ClipboardChanged;
protected override void Dispose(bool disposing)
{
ChangeClipboardChain(this.Handle, nextClipboardViewer);
}
[DllImport("User32.dll")]
protected static extern int SetClipboardViewer(int hWndNewViewer);
[DllImport("User32.dll", CharSet = CharSet.Auto)]
public static extern bool ChangeClipboardChain(IntPtr hWndRemove, IntPtr hWndNewNext);
[DllImport("user32.dll", CharSet = CharSet.Auto)]
public static extern int SendMessage(IntPtr hwnd, int wMsg, IntPtr wParam, IntPtr lParam);
protected override void WndProc(ref System.Windows.Forms.Message m)
{
// defined in winuser.h
const int WM_DRAWCLIPBOARD = 0x308;
const int WM_CHANGECBCHAIN = 0x030D;
switch (m.Msg)
{
case WM_DRAWCLIPBOARD:
OnClipboardChanged();
SendMessage(nextClipboardViewer, m.Msg, m.WParam, m.LParam);
break;
case WM_CHANGECBCHAIN:
if (m.WParam == nextClipboardViewer)
nextClipboardViewer = m.LParam;
else
SendMessage(nextClipboardViewer, m.Msg, m.WParam, m.LParam);
break;
default:
base.WndProc(ref m);
break;
}
}
void OnClipboardChanged()
{
try
{
MessageBox.Show("asda");
string CheckStr = Clipboard.GetText();
//IDataObject iData = Clipboard.GetDataObject();
if (ClipboardChanged != null)
{
ClipboardChanged(this, new ClipboardChangedEventArgs(CheckStr));
}
}
catch (Exception e)
{
// Swallow or pop-up, not sure
// Trace.Write(e.ToString());
MessageBox.Show(e.ToString());
}
}
}
public class ClipboardChangedEventArgs : EventArgs
{
// public readonly IDataObject DataObject;
public ClipboardChangedEventArgs(string dataObject)
{
Form1 object1 = new Form1();
object1.InputStr(dataObject);
}
}
}
