Media Player control in Visual Basic.NET

Submitted by joken on Monday, September 2, 2013 - 13:50.

In this tutorial we're going to focus on using Windows Media Player in Visual Basic .Net where user is able to play music, videos and viewing of different formats of pictures. Basically the Windows Media Player does not exist in the components portion of the toolbox. So to add the Windows Media Player we need to add it in the toolbox. The first step would be, go to the toolbox and Right click then select Choose Items and the Customize Toolbox dialog box will open. Then Select Windows Media Player on the COM Components. Then click ok. After this step the Windows Media Player control will appear on the current tab. After this process we can add now Windows Media Player to our Form and the default name of this control is “AxWindowsMediaPlayer1”. And these can be changed according to what we wanted for example “myPlayer” so that it could be more easily to read and remember. The next process is that we're going to add other controls to our form such as Listbox, FolderBrowserDialog, MenuStrip and StatusStrip. Plan the objects and Properties

Object	                Property	 Settings
Form1	                Name	         mainFrm
	                Text	         Personal Media Player
	                StartPosition	 CenterScreen
	                ControlBox	 False
AxWindowsMediaPlayer1	Name	         myPlayer
Listbox          	Name	         List
MenuStrip1	        Name	         MenuStrip1
StatusStrip1	        Name	         StatusStrip1
FolderBrowserDialog1	Name	         FolderBrowserDialog1

On the MenuStrip1 we need to add two main menus such Libraries and View. The Libraries have also submenus like Music, Videos, Images and Exit. And for the View submenu is only Playlist Editor. This should look like as shown below.

And the final design looks like as shown below.

After designing our user interface let’s proceed in adding functionalities to our program. First step double click the main form or we have name it into “mainFrm” to shift our view Designer into view Code. Then on the mainFrm_Load add this code.

list.Items.Clear()      ' clear all currect content of the list
list.Hide()             ' it will hide the on the main form
myPlayer.Width = 787    ' it will resize the width of myPlayer into 787

and on below of our Public Class mainFrm add this declaration of variable that will hold full path of our folder. And it will like this.

Public Class mainFrm
    Dim folderpath As String

After adding this code we’re going create a sub procedure that we will be using it for our program later.

Public Sub jokenresult()
        If list.Items.Count > 0 Then
            list.Show()
            myPlayer.Width = 577
            statresult.Text = list.Items.Count & " Items"
        Else
            list.Hide()
            myPlayer.Width = 787
        End If
    End Sub

Next we will add functionality to the one sub menu items under libraries the Music. To do this just simply double click the Music sub menu. Then you will be redirected to source code view and add this code so it should now look like as shown below.

Private Sub MusicToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MusicToolStripMenuItem.Click
        Try
            'it will open the folder dialog where you can select where is the specific folder of your music
            FolderBrowserDialog1.ShowDialog()
 
            If DialogResult.OK Then
                'if true that if you click ok on the folder dialog box then
                'it will get the selected path of your folder and store it into di variable
                Dim di As New IO.DirectoryInfo(FolderBrowserDialog1.SelectedPath)
                'in this line of code it will get all the specific file that has the .mp3 extension and store it into diar1 variable
                Dim diar1 As IO.FileInfo() = di.GetFiles("*.mp3")
                Dim dra As IO.FileInfo
                'and in this line it will gather all information with regardsto fullpath and names of all files and store it to the folderpath variable
                folderpath = di.FullName.ToString
                list.Items.Clear()
                ' list the names of all files in the specified directory
 
                For Each dra In diar1
                    Dim a As Integer = 0
                    ' a = a + 1
                    list.Items.Add(dra)
                Next
                'it will call the sub procedure jokenresult() to perform some actions
                jokenresult()
            End If
        Catch ex As Exception
            'if errors occur then the program will catch it and send it back to the user.
            MsgBox(ex.Message, MsgBoxStyle.Information)
        End Try
 
    End Sub

And this is the sample running program playing a selected music.

And this is the sample running program playing a selected Movie.

And finally this is all of the source code.
