First step: How to open a form in a thread

            Sendemailprogress progress=new sendemailprogress (); Add form Close Event progress. Closing + = (s, ev) = = {if (progress.                        Isenabledcloseform) {} else { Ev.                Cancel = true;//close the form}}; Control.checkforillegalcrossthreadcalls = false; In this class we do not check whether a cross-thread call is legal thread thread = new Thread (New Parameterizedthreadstart (Showcommonprogressformdialog                )); Thread.                Start ();                    if (IsFirst) {thread.sleep (5000);                IsFirst = false; } progress.            Writemessage ("", "", "");//private static void Showcommonprogressformdialog (Object message) {try {int num = (int) progress.            ShowDialog ();            } catch (Exception){            }        } 

Step Two: Call methods in the body of the window.

Private delegate void Writemessagehandler (String message, enumcolorints ECI, bool isneedsetsize);        <summary>///Show message///</summary>//<param name= "message" ></param> <param name= "ECI" ></param> private void Writemessage (String message, Enumcolorints Eci,bool is              needsetsize) {Font font = new Font (fontfamily.genericmonospace, +, fontstyle.regular);            True if the control's System.Windows.Forms.Control.Handle is created on a different thread than the calling thread (indicating that you must call the control via the Invoke//method); (Note: Gets a value that indicates whether the caller must call the Invoke method when making a method call to the control, because the call is in a thread other than the thread on which the control is created.)                ) if (invokerequired) {Writemessagehandler handler = Writemessage;            Invoke (Handler, new object[] {message, ECI, isneedsetsize});                } else {int index = RtMessageBox.Text.Length;           Rtmessagebox.appendtext (message);     Rtmessagebox.select (index, message.                Length);                            else {switch (ECI) {case enumcolorints.red:                            Rtmessagebox.selectioncolor = color.red;                        Break                            Case EnumColorInts.Green:RtMessageBox.SelectionColor = Color.green;                        Break Case EnumColorInts.Black:default:RtMessageBox.SelectionColor = color.b                            Lack                    Break                }} rtmessagebox.appendtext ("\ r \ n");                Rtmessagebox.selectionstart = RtMessageBox.Text.Length;            Rtmessagebox.scrolltocaret (); }        }

The above only as a personal learning accumulation ...
