C#完整的截圖原始碼及註釋
/*這是一個完整的截圖程式,除錯通過,你可以根據昨天的,視窗殺手程式,也給這個截圖加上熱鍵,和視窗放到系統托盤上,這樣,截圖就不會將程式本身也給顯示在截出來的圖片上了。過兩天,我會寫上這兩個功能的。不過,最好,你能自己也試試。可以在這兒下載http://metababy.chinay.com/sp/metababy/08383052696.rar原始檔的打包*/using System;using System.Drawing;using System.Drawing.Imaging;using System.Collections;using System.ComponentModel;using System.Windows.Forms;using System.Data;
