Question

My WinForms application has a TextBox that I\'m using as a log file. I\'m appending text without the form flickering using TextBox.AppendText(string);, however

Answer 1

I found a solution looking on the internet:

    [System.Runtime.InteropServices.DllImport("user32.dll")]

    public static extern bool LockWindowUpdate(IntPtr hWndLock);

    internal void FillTB(TextBox tb, string mes) 
    {
       try
       {
          LockWindowUpdate(tb.Handle);

          // Do your thingies with TextBox tb
       }
       finally
       {
          LockWindowUpdate(IntPtr.Zero);
       }
    }
