string s = "測試文字，隨便寫一些文字"; foreach (char c in s) { textBox1.AppendText(c.ToString()); int tick = Environment.TickCount; //間隔時間，按你自己喜好，我這裡寫100毫秒 while

private void button1_Click(object sender, EventArgs e) { RunWhenStart(false, "mystarton", @"C:/Program Files/UltraEdit/Uedit32.exe"); } /// <summary> /// 開機啟動項 /// </summary> ///

       //在Form的屬性中要設定 AlowDrop為true        private void Form1_DragEnter(object sender, DragEventArgs e)        {            if (e.Data.GetData(DataFormats.FileDrop) != null)            {                e.Effect = DragDropEffects.Copy;            }   

正常來說，那麼winform是擷取不到EXE的傳回值，這時我所用的方法是把EXE中的值寫到csv檔案中，然後winform去讀取csv   private void btnGoodsSelect_Click(object sender, EventArgs e)        {            ParameterizedThreadStart pts = new ParameterizedThreadStart(RunCommand);            Thread

 [System.Runtime.InteropServices.DllImport("user32.dll ")]        public static extern int SetWindowLong(IntPtr hWnd, int nIndex, int wndproc);        [System.Runtime.InteropServices.DllImport("user32.dll ")]        public static extern int GetWindow

1. 最簡單的是可以直接用Console.Beep();或者Console.Beep(frequency, duration);可以自訂任意Hz的音頻，和任意時間；不過我在win7的環境下產生的Exe在xp系統下會從主機發出聲音，原因未知；可能是系統不同，編譯後的異常。 2.也可以使用dll類  [DllImport("kernel32.dll")]        private static extern int Beep(int dwFreq, int

堆排序的主要原理就是利用堆的特點，首先產生最大堆，然後每次取堆的root和最後一個葉子交換，剔除最後葉子。然後再次產生最大堆，迴圈。  /// <summary>        /// 堆排序        /// </summary>        /// <param name="Myarray"></param>        /// <returns></returns>        private int[]

            string strConn = @"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=D:/A.mdb";            OleDbConnection odcConnection = new OleDbConnection(strConn); //2、開啟串連 C#操作Access之按列讀取mdb               odcConnection.Open(); //建立SQL查詢              

在頁面page_load中： int num = 0;                    for (int i = 0; i < dt_data.Rows.Count; i++)                    {                        dgv.Rows.Add();                        int n = dgv.Rows.Count - 1;                        for (int j = 2; j

private void Form1_Load(object sender, EventArgs e) { TimeSpan ts1 = new TimeSpan(DateTime.Now.Ticks); //擷取目前時間的刻度數 //你的代碼或者其他動作 double dout = 1; for (int i = 1; i <= 10; i++) {

[DllImport("User32.dll", EntryPoint = "FindWindow")] private static extern IntPtr FindWindow(string lpClassName, string lpWindowName); //添加引用 找到視窗控制代碼 private void button1_Click_1(object sender, EventArgs e) { IntPtr

 *我也是抄別人的，禁止關閉沒什麼問題，當然只要別在進程管理器裡關就行。呵呵禁止拖動有問題，就是用標題列左邊的表徵圖菜單，是可以拖動表單的。【解決辦法應該是，用this.position來解決吧】  private const int SC_CLOSE = 0xF060; private const int MF_ENABLED = 0x00000000; private const int MF_GRAYED = 0x00000001;

private void Form1_MouseClick(object sender, MouseEventArgs e) { System.Text.StringBuilder messageBoxCS = new System.Text.StringBuilder(); messageBoxCS.AppendFormat("{0} = {1}", "Button", e.Button);

網路編程真麻煩,只能這麼死記硬背了. private void myButton1_Click(object sender, EventArgs e) { //建立串連,發送訊息 System.Net.Sockets.TcpClient tcp = new System.Net.Sockets.TcpClient("192.168.24.23", 8051); string signal = "create

private void myButton2_Click(object sender, EventArgs e) { //Execute("net user zero 0571m.com /add", 0); string output = Execute("ver" + "/r/n", 0); Console.WriteLine(output); } public static

C#遍曆指定檔案夾中的所有檔案 DirectoryInfo TheFolder=new DirectoryInfo(folderFullName);//遍曆檔案夾foreach(DirectoryInfo NextFolder in TheFolder.GetDirectories())   this.listBox1.Items.Add(NextFolder.Name);//遍曆檔案foreach(FileInfo NextFile in TheFolder.GetFiles())

取項目名稱：        static string AppName()        {            string fullstr = Assembly.GetExecutingAssembly().FullName;            return fullstr.Substring(0, fullstr.IndexOf(","));        } 根據表單上的控制項名稱取控制項           public static Control

雖然，對於N個TIMER類不瞭解，對於TICK 和 E.....的也不瞭解， 但這段代碼管用，就這樣吧。  Timer t = new Timer(); int labelX; int labelY; private void Form1_Load(object sender, EventArgs e) { string news1 = "434534"; label1.Text =
