[C#] Adjusting system sound volume

[yyy]

Hi,

I was wondering if somebody knows how I can adjust the system sound volume using C#.NET ? I want my application to increase or decrease the system's sound volume. I want to develop an application that functions similar to how Windows volume control functions:

Can somebody please tell me how to do it? Or at least, tell me how to adjust the system's volume control?

Thanks in advance - any help will be appreciated :)

P.S. - I will also be happy to accept a VB.NET code - I can try to convert it to C#.

Well, I think I've already found out how to so it in here: http://www.groupsrv.com/dotnet/viewtopic.php?p=141745 :whistle:

Glad you posted! I looked for something like that in the past one time when I was curious. Thanks. (Y)

Just to let you know, as far as I know there is one minor bug in that code.. when you change the volume it resets the balance of the speakers. :)

Wow, that's a lot of code for just increasing volume.

 

using System;
using System.Windows.Forms;
using System.Runtime.InteropServices;

namespace Test
{
public partial class Form1 : Form
{
private const int APPCOMMAND_VOLUME_MUTE = 0x80000;
private const int APPCOMMAND_VOLUME_UP = 0xA0000;
private const int APPCOMMAND_VOLUME_DOWN = 0x90000;
private const int WM_APPCOMMAND = 0x319;

[DllImport("user32.dll")]
public static extern IntPtr SendMessageW(IntPtr hWnd, int Msg,
IntPtr wParam, IntPtr lParam);

public Form1()
{
InitializeComponent();
}

private void btnMute_Click(object sender, EventArgs e)
{
SendMessageW(this.Handle, WM_APPCOMMAND, this.Handle,
(IntPtr)APPCOMMAND_VOLUME_MUTE);
}

private void btnDecVol_Click(object sender, EventArgs e)
{
SendMessageW(this.Handle, WM_APPCOMMAND, this.Handle,
(IntPtr)APPCOMMAND_VOLUME_DOWN);
}

private void btnIncVol_Click(object sender, EventArgs e)
{
SendMessageW(this.Handle, WM_APPCOMMAND, this.Handle,
(IntPtr)APPCOMMAND_VOLUME_UP);
}
}
}
