string " /sound/msg.wav " // Application.startuppath: The program EXE location, you can also directly write a path to music New  ////player. Playlooping (); // play the player. Play ();

Two: C # call EXE

Logout of a program as an example: Click to log out after the program opened, and then close the program

if (process==null)  {     string path = Application.startuppath; // This path is the absolute path to the EXE program you are calling.     New System.Diagnostics.Process (); // Create a new process     Process. Startinfo.filename = assembly.getexecutingassembly (). Manifestmodule.fullyqualifiedname; // gets the file name of its own EXE or DLL     Process. Startinfo.workingdirectory = path;     Process. Start ();  }      this. Close ();

Three: Program Display clock

Write code in a time control that is set to 1000ms

   Private void Statetime_tick (object  sender, EventArgs e)        {            // Show status bar            " Soul-Heart Home improvement      budget software " + DateTime.Now.ToString ("yyyy mm month DD Day HH:mm:ss");        }

Four: Set the transparency of the custom control

         PublicUserControl1 () {InitializeComponent (); //set style to support transparent background color             This. SetStyle (Controlstyles.supportstransparentbackcolor,true);  This. BackColor = Color.FromArgb ( -, $, $, $); }        protected Override voidOnPaint (PaintEventArgs e) {Base.            OnPaint (e); E.graphics.drawstring ("",NewFont ("Tahoma",8.25f), Brushes.Red,NewPointF ( -, -)); }
