Create and add a playlist (C #)

Code

 // Create a dialog box to open the object instance
OpenFileDialog open = new OpenFileDialog ();
// Set to open multiple files
Open. Multiselect = true;
// Set the format of the opened file
Open. filter = "Mp3 file | *. mp3 | Wav file | *. wav | Wma file | *. wma | Wmv file | *. wmv | all formats | *. *";
// Determine whether to click OK
If (open. ShowDialog () = DialogResult. OK)
{
// Create a playlist named aa
AxWindowsMediaPlayer1.currentPlaylist = axWindowsMediaPlayer1.newPlaylist ("aa ","");
// Traverse the opened set
Foreach (string fn in open. FileNames)
{
// Add a playlist
AxWindowsMediaPlayer1.currentPlaylist. appendItem (axWindowsMediaPlayer1.newMedia (fn ));
}
} // Loop playback axWindowsMediaPlayer1.settings. setMode ("loop", true );
// Play

Private void ResizeOriginal ()
{

Int intHeight = axWindowsMediaPlayer1.currentMedia. imageSourceHeight;
AxWindowsMediaPlayer1.Width = intWidth + 2;

}

 

 

Open a media file and play it back:

Dim filePath As String
With Me. OpenFileDialog1
. Title = "open a voice file"
. CheckPathExists = True
. CheckFileExists = True
. Multiselect = False
. Filter = "mp3 file (*. mp3) | *. mp3 | all files (*. *) | *.*"
If. ShowDialog = DialogResult. Cancel Then
Exit Sub
End If
FilePath =. FileName
End
Me. Text = "PC repeater-file" & filePath
AxWindowsMediaPlayer1.URL = filePath
Try
Me. AxWindowsMediaPlayer1.Ctlcontrols. play ()
Catch ex As Exception
MsgBox ("sorry, you cannot play audio files in this format", MsgBoxStyle. OKOnly, "PC repeater ")
Exit Sub
End Try

Note:

In AxWindowsMediaPlayer1.URL, the URL indicates the file Name to be played. The original Name attribute is canceled.

AxWindowsMediaPlayer1.Ctlcontrols. play () playback, other attributes such as Pause and Stop.

AxWindowsMediaPlayer1.settings. balance indicates the audio channel settings for media playback, 0 indicates the balance, and-1 and 1 indicates the Left and Right audio channels.

AxWindowsMediaPlayer1.currentMedia. duration indicates the duration of the file to be played. You can use it to obtain the file length.

AxWindowsMediaPlayer1.Ctlcontrols. currentPosition indicates the current playback position of the file being played. This attribute can be used to set forward and backward for the media file. For example

AxWindowsMediaPlayer1.Ctlcontrols. currentPosition + 1 indicates the first time unit forward.

AxWindowsMediaPlayer1.settings. rate: Specifies the playback rate. Generally, the unit of kbps is displayed after the value is multiplied by 16.

 

 

Note: In the above program, if you add:

Msgbox (AxWindowsMediaPlayer1.currentMedia. duration. ToString)

The display result may be 0. Therefore, the playback duration of the file may not be obtained at this time, which is prone to errors. Therefore, you can add a timer control when using it:

Private Sub timereffectick (ByVal sender As Object, ByVal e As System. EventArgs) Handles Timer1.Tick
EndPoint = AxWindowsMediaPlayer1.currentMedia. duration
If EndPoint = 0 Then Exit Sub ', it may take some time to open the media file. It is waiting for the opening of the media file.

Msgbox (AxWindowsMediaPlayer1.currentMedia. duration. ToString)

End Sub

In this case, msgbox displays the playback length of the file.

2. Ctlcontrols attributes

For example, AxWindowsMediaPlayer1.Ctlcontrols. forward ()

(5) fastreverse

Form name. Control name. Ctlcontrols. fastreverse ()

For example, AxWindowsMediaPlayer1.Ctlcontrols. fastreverse ()

6. Attribute CurrentPosition

Used to obtain the current playback progress of a multimedia file. The value is of the numerical type and the format is as follows:
