VB 2008 中的 IMAPI2 进度条

我开始制作刻录 CD/DVD 的程序,一切都很好。 我找到了使用 IMAPI2 API 进行刻录的方法,但现在我遇到了问题: 我无法获得燃烧的进度条。 代码如下:

Dim CDD1 As New IMAPI2.MsftDiscMaster2
Dim CDD2 As New IMAPI2.MsftDiscRecorder2

Dim FSI As New IMAPI2FS.MsftFileSystemImage
Dim CDD3 As New IMAPI2.MsftDiscFormat2Data

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
    Dim Index = 0
    Dim UniqueID = ""
    Dim Directory
    Dim Path = "C:\lll"
    Dim result
    Dim Stream

    Label1.Text = "----- Started -----."

    UniqueID = CDD1.Item(Index)
    Label1.Text = Label1.Text & vbCrLf & "ID found: " & UniqueID

    CDD2.InitializeDiscRecorder(UniqueID)
    Label1.Text = Label1.Text & vbCrLf & "Recorder selected!"

    Directory = FSI.Root
    Label1.Text = Label1.Text & vbCrLf & "Directory is here: " & Directory.ToString

    CDD3.Recorder = CDD2
    Label1.Text = Label1.Text & vbCrLf & "Recorder 2 selected!"

    CDD3.ClientName = "IMAPI2 TEST"
    Label1.Text = Label1.Text & vbCrLf & "Client Name Selected!"

    FSI.ChooseImageDefaults(CDD2)
    Label1.Text = Label1.Text & vbCrLf & "Default selected!"

    Directory.AddTree(Path, False)
    Label1.Text = Label1.Text & vbCrLf & "Directory added!"

    result = FSI.CreateResultImage()
    Stream = result.ImageStream

    Label1.Text = Label1.Text & vbCrLf & "Writing content to disc..."

    If (CDD3.IsCurrentMediaSupported(CDD2) = True) Then
        If (CDD3.IsRecorderSupported(CDD2) = True) Then

            CDD3.Write(Stream)

        Else
            MsgBox("Not Suported Recorder!")
        End If
    Else
        MsgBox("Not Suported Media!")
    End If

    Label1.Text = Label1.Text & vbCrLf & "----- Finished -----"

End Sub

当命令

CDD3.Write(Stream)

被触发时,程序冻结,直到数据完全烧录后才响应。

有什么方法可以阻止这种情况,阻止程序冻结并启用进度条吗?

谢谢。

I start making program that will burn CD/DVDs, and everything is okay.
I found way to burn with IMAPI2 API, but now I have problem:
I can't get progress bar of that burning.
Here is code:

Dim CDD1 As New IMAPI2.MsftDiscMaster2
Dim CDD2 As New IMAPI2.MsftDiscRecorder2

Dim FSI As New IMAPI2FS.MsftFileSystemImage
Dim CDD3 As New IMAPI2.MsftDiscFormat2Data

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
    Dim Index = 0
    Dim UniqueID = ""
    Dim Directory
    Dim Path = "C:\lll"
    Dim result
    Dim Stream

    Label1.Text = "----- Started -----."

    UniqueID = CDD1.Item(Index)
    Label1.Text = Label1.Text & vbCrLf & "ID found: " & UniqueID

    CDD2.InitializeDiscRecorder(UniqueID)
    Label1.Text = Label1.Text & vbCrLf & "Recorder selected!"

    Directory = FSI.Root
    Label1.Text = Label1.Text & vbCrLf & "Directory is here: " & Directory.ToString

    CDD3.Recorder = CDD2
    Label1.Text = Label1.Text & vbCrLf & "Recorder 2 selected!"

    CDD3.ClientName = "IMAPI2 TEST"
    Label1.Text = Label1.Text & vbCrLf & "Client Name Selected!"

    FSI.ChooseImageDefaults(CDD2)
    Label1.Text = Label1.Text & vbCrLf & "Default selected!"

    Directory.AddTree(Path, False)
    Label1.Text = Label1.Text & vbCrLf & "Directory added!"

    result = FSI.CreateResultImage()
    Stream = result.ImageStream

    Label1.Text = Label1.Text & vbCrLf & "Writing content to disc..."

    If (CDD3.IsCurrentMediaSupported(CDD2) = True) Then
        If (CDD3.IsRecorderSupported(CDD2) = True) Then

            CDD3.Write(Stream)

        Else
            MsgBox("Not Suported Recorder!")
        End If
    Else
        MsgBox("Not Suported Media!")
    End If

    Label1.Text = Label1.Text & vbCrLf & "----- Finished -----"

End Sub

When command

CDD3.Write(Stream)

is triggered, program freeze, and don't respond until data is burned completely.

Is there any way to stop this, to stop program freezing and enabling progress bar?

Thanks.

您需要使用线程。因此,在按钮单击事件处理程序中,您启动一​​个新线程来执行实际的刻录,当它在单独的线程中进行时,主线程可以继续更新 GUI(包括进度条)。

请参阅 Thread.Start 获取简单示例,如果您想了解更多信息,我建议从这里开始:托管线程

You need to use threading. So in your button click event handler you start off a new thread that does the actual burning and while that's going on in it's separate thread, the main thread can continue to update the GUI (including your progress bar).

See Thread.Start for a simple sample and if you want further information I'd suggest starting here: Managed Threading
