總結
1、cmd關機相關命令
取消任務命令:shutdown -a重啟命令:shutdown -r -t sec (于sec秒后重啟)關機命令:shutdown -s -t sec (于sec秒后關機) at 23:00 shutdown -s (在23:00執行shutdown -s,即在23:00關機。) at 某個時間 執行某個動作/應用 (win7測試管理員權限)
取消at計劃(1是ID)
2、更改應用圖標
3、窗體設置為無邊框樣式之后,就拖動不了了。可以通過監聽鼠標動作,在窗體范圍內,窗體跟隨鼠標的移動。對于貼邊其實就是設置窗體的位置。
4、調用第三方程序
Process process = new Process()//創建進程process.StartInfo.FileName = exePath;//exePath:調用程序的路徑process.Start();//開始調用執行process.WaitForExit();//等待退出process.Close();//關閉進程
