vb.net 怎么添加Windows Media Player控件? 注意是VB.NET不是VB

“工具箱”中单击右键，选择“选择项”菜单，打开“选择工具箱项”窗口，选择“COM组件”标签，在列表中找到并勾选“Windows Media Player”组件，单击“确定”按钮。将该组件添加到指定的工具箱选项卡中，然后在工具箱里面找 Windows Media Player 控件，拉到form里面，拉出来的控件就是AxWindowsMediaPlayer

VB.NET 如何动态添加组件，如FileSystemWatcher，并且响应同一事件？

For Each i In My.Computer.FileSystem.Drives

Dim FSW As New FileSystemWatcher

FSW.NotifyFilter = NotifyFilters.FileName

FSW.Path = i.Name.ToString

FSW.Filter = "*.txt"

AddHandler FSW.Changed, AddressOf FileSystemWatcher1_Changed '与FileSystemWatcher1_Changed事件绑定，以下同。

AddHandler FSW.Created, AddressOf FileSystemWatcher1_Created

AddHandler FSW.Deleted, AddressOf FileSystemWatcher1_Deleted

AddHandler FSW.Disposed, AddressOf FileSystemWatcher1_Disposed

AddHandler FSW.Error, AddressOf FileSystemWatcher1_Error

AddHandler FSW.Renamed, AddressOf FileSystemWatcher1_Renamed

FSW.EnableRaisingEvents = True

Next

上面代码放到一个调用过程中

Private Sub FileSystemWatcher1_Created(sender As Object, e As FileSystemEventArgs) Handles FileSystemWatcher1.Created

‘我用fsw的path属性区别多个分区，你用自己的代码就行，如果你没有创建FileSystemWatcher1，就把Handles FileSystemWatcher1.Created删除。

If sender.path = "C:\" Then

'代码

ElseIf sender.path = "D:\" Then

'代码

ElseIf sender.path = "F:\" Then

ElseIf sender.path = "H:\" Then

'……

End If

End Sub

如何在vb.net里面动态添加控件

Private WithEvents NewTextBox As TextBox

'通过使用WithEvents关键字声明一个对象变量为新的命令按钮

Private Sub Command1_Click()

If NewTextBox Is Nothing Then

Set NewTextBox = Controls.Add("VB.TextBox", "cmdNew", Form1)

NewTextBox.Move 200, 200

NewTextBox.Width = Form1.Width - 450

NewTextBox.Height = Form1.Height - 1400

NewTextBox.Visible = True

End If

End Sub

Private Sub Command2_Click()

If NewTextBox Is Nothing Then

Exit Sub

Else

Controls.Remove NewTextBox

Set NewTextBox = Nothing

End If

End Sub
