windows medie player （以下简称WMP），默认不在vs2005的toolbox中，因此，需要手动添加，下面是在vs2005中使用WMP控件的步骤:
The following is the walkthrough to use a Windows Media Player COM
component in a WinForms application.
1. If the Windows Media Player COM component is not present in the Toolbox,
right-clikc on the Toolbox and choose 'Choose Items'. In the 'Choose
Toolbox Items' dialog, switch to the 'COM Components' tab. Navigate to
'Windows Media Player' (whose path is 'c:\Windows\system32\wmp.dll') and
select the checkbox before this item. Press OK.
2. Drag&drop the Window Media Player COM component from Toolbox onto a
form. At this time, VS IDE will generate wrapper classes for this COM
component automatically. COM components are not managed, so we couldn't use
them directly in .NET applications.
If you expand the Reference node under the project node in the Solution
Explorer, you should see two references called 'AxWMPLib' and 'WMPLib' are
added.
3. You may add the following code to the form:
private void Form1_Load(object sender, EventArgs e)
{
// the 'axWindowsMediaPlayer1' is the name of the Windows Media Player
COM component on the form
MessageBox.Show(this.axWindowsMediaPlayer1.versionInfo);
this.axWindowsMediaPlayer1.URL = "the path of the video/audio file";
}
4. Build the project. Go to the bin\debug folder of the application and you
should see two files called 'AxInterop.WMPLib.dll' and
'Interop.WMPLib.dll', which are the dll files that contain the wrapper
classes for the Windows Media Player COM component.
