如何使用进度条增加窗口媒体播放器的音量 [英] how to use progress bar for increasing volume for window media player

问题描述

我正在使用vb.net制作媒体播放器软件

我已使用进度条来增加或减少音量.我无法为其编写确切的代码.
我希望当我单击进度条时，音量应该增加还是减少取决于用户要求，就像我们在vlc或window media player之类的媒体播放器中看到的那样.

我尝试了以下代码

I am making a media player software using vb.net

I have taken a progress bar to increase or decrease a volume.I am not not able to write exact code for it.
I want that when I click progress bar volume should increse or decrease depends upon user requirements as we see in media player like vlc or window media player.

i tried following code

Private Sub ProgressBar1_Click_2(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ProgressBar1.Click
       ProgressBar1.PerformStep()
       wmp.settings.volume = ProgressBar1.Value
       If ProgressBar1.Value = 100 Then
           ProgressBar1.Value = 40
       End If

   End Sub

请就此

推荐答案

为我提供帮助，为什么不使用TrackBar控件呢?使用进度条，您无法将音量调低*.

Why don''t you the a TrackBar control instead? With a progress bar, you have no way to turn the volume *down*.

这是按照约翰的建议对后续问题的解答:

处理事件System.Windows.Forms.TrackBar.ValueChanged(不单击)；使用传递给事件句柄的event arguments参数访问发送方并读取其int属性System.Windows.Forms.TrackBar.Value的值；假设它已分配给变量value.在此事件处理程序的主体中分配:wmp.settings.volume = value.

This is the answer to a follow-up question following the advice by John:

Handle the event System.Windows.Forms.TrackBar.ValueChanged (not Click); use the event arguments parameter passed to your event handle to access the sender and read the value of its int property System.Windows.Forms.TrackBar.Value; let''s say it''s assigned to the variable value. Assign: wmp.settings.volume = value, in the body of this event handler.

See: http://msdn.microsoft.com/en-us/library/system.windows.forms.trackbar.aspx[^].
