摘要:[C#.NET][VB.NET][VB6] 監視剪貼簿內容

.Net Framwork中可以利用System.Windows.Forms命名空間的Clipboard 類別來達到像Office的剪貼簿監視，以下是小小的範例。

C#.NET 2005：

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;

namespace WindowsApplication1
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void timer1_Tick(object sender, EventArgs e)
        {
            if(Clipboard.ContainsText()) richTextBox1.Text=Clipboard.GetText();
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            timer1.Interval = 1000;
            timer1.Start();

        }
    }
}

VB.NET 2005：

Public Class Form1
    Dim i

    Private Sub Form1_Activated(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Activated
        i = 0
        Clipboard.Clear()
    End Sub
    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        Timer1.Enabled = True
        Timer1.Interval = 1000
        Timer1.Start()
    End Sub

    Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
        Dim strTem As String
        If Clipboard.ContainsText Then '判斷是剪貼簿否有內容
            i = i + 1
            strTem = Clipboard.GetText() '貼到變數
            If i = 1 Then
                RichTextBox1.Text = "第" & i & "次複製" & vbCrLf & strTem & vbCrLf
            Else
                RichTextBox1.Text = RichTextBox1.Text & vbCrLf & "第" & i & "次複製" & vbCrLf & strTem & vbCrLf
            End If
            Clipboard.Clear()
        End If
    End Sub
End Class

執行畫面結果如下

VB6：當然也不能少了老牌的它

Option Explicit
Dim i
Private Sub Form_Activate()
    i = 0
    Clipboard.Clear
End Sub

Private Sub Form_Load()
    Timer1.Enabled = True
    Timer1.Interval = 1000
End Sub

Private Sub Timer1_Timer()
    Dim strTem As String
    If Clipboard.GetFormat(vbCFText) Then
        i = i + 1
        strTem = Clipboard.GetText(vbCFText)
        If i = 1 Then
            Text1.Text = "第" & i & "次複製" & vbCrLf & strTem & vbCrLf
        Else
            Text1.Text = Text1.Text & vbCrLf & "第" & i & "次複製" & vbCrLf & strTem & vbCrLf

        End If
        Clipboard.Clear
    End If
End Sub

執行結果畫面如下
