My project is to play 2 wave files (play x0.wav then play WaitOneSecond.wave then play x1.wav)
i added Windows Media Player .COM not the Windows Media Player from toolbox
WaitOneSecond.wave is an empty file it is just to insert a gap between x0.wav and x1.wav
my error is i could only play x0.wav
if i removed the if satement from the code below it only play x1.wav ,i could not here x0.wav
as far as i know ,the variable
PlayerFinished
shall be equal to 1 if wav file ended
so how can i play the 2 wave files ?
thanks

C#

using WMPLib;
namespace zenat
{
    public partial class Form1 : Form
    {
        int PlayerFinished = 0;
        WMPLib.WindowsMediaPlayer Player;
        public Form1()
        {
            InitializeComponent();
            //Sound
            Player = new WMPLib.WindowsMediaPlayer();
            Player.PlayStateChange +=
                new WMPLib._WMPOCXEvents_PlayStateChangeEventHandler(Player_PlayStateChange);
            Player.MediaError += new WMPLib._WMPOCXEvents_MediaErrorEventHandler(Player_MediaError);
            Player.settings.volume = 100;
        }
        //
        private void Player_PlayStateChange(int NewState)
        {
            if ((WMPLib.WMPPlayState)NewState == WMPLib.WMPPlayState.wmppsStopped)
            PlayerFinished = 1;
        }
        //
        private void Player_MediaError(object pMediaObject)
        {
            MessageBox.Show("Cannot play media file.");
        }
        //
        private void pronouncClick(object sender, EventArgs e)
        {   string sound;
            //PlayerFinished = 0;
            //Player.URL = "PalySilence4_OneSecond.wav";

            PlayerFinished = 0;
            sound = "x0.wav";
            if (File.Exists(sound)) Player.URL = sound;
            else Player.URL = "PalySilence4_OneSecond.wav";//

            if (PlayerFinished == 1)//start playing x1.wav if only the x0.wav ended 
            {
                //PlayerFinished = 0;
                //Player.URL = "PalySilence4_OneSecond.wav";

                PlayerFinished = 0;
                sound = "x1.wav";
                if (File.Exists(sound)) Player.URL = sound;
                else Player.URL = "PalySilence4_OneSecond.wav";

Without that I followed all details : Do you have a thought that two songs simultaneously play need two players?

Engineer khalid 23-Dec-14 12:57pm

i want to play song one when song one finished and using the same player i want to play song two ,untill now things seems to me right please show me my error

Engineer khalid 23-Dec-14 13:13pm

look at this codes
x=10; Area=x*2; MessageBox.Show("Area="+Area.ToString());
x=100; Area=x*2; MessageBox.Show("Area="+Area.ToString());
so i am reusing same x vaiable ,so what is wrong with Player
do you mean i have to use player1 to play song1,then use palyer2 to play song2 ?

The following has solved the error
int NwavFilePlayed = 0;//declared globalley

private void Player_PlayStateChange(int NewState)
{
if ((WMPLib.WMPPlayState)NewState == WMPLib.WMPPlayState.wmppsStopped)
{
NwavFilePlayed++;
if (NwavFilePlayed < 5)
{
//MessageBox.Show("NwavFilePlayed=", NwavFilePlayed.ToString());
Pronounce("hellow");
}
//else MessageBox.Show("no more file to play", "NwavFilePlayed=" + NwavFilePlayed.ToString());

}
}//Player_PlayStateChange

private void Pronounce(string str)//
{
string sound;

Player = new WMPLib.WindowsMediaPlayer();
Player.PlayStateChange +=
new WMPLib._WMPOCXEvents_PlayStateChangeEventHandler(Player_PlayStateChange);
Player.MediaError += new WMPLib._WMPOCXEvents_MediaErrorEventHandler(Player_MediaError);
Player.settings.volume = 100;

//MessageBox.Show(str, "NwavFilePlayed=" + NwavFilePlayed.ToString());

sound = "x"+NwavFilePlayed.ToString()+".wav";
if (File.Exists(sound)) Player.URL = sound;
else Player.URL = "PalySilence4_OneSecond.wav";//
}
