SYMPTOMS
In Windows 2000, the .wav files that are opened as a Uniform Resource Locator (URL) may not play when you use the Windows Media Player version 6.4 ActiveX control (Msdxm.ocx) in a Microsoft Visual Basic program, and an error message is not displayed.



CAUSE
This problem can occur because the Quartz.dll file in Windows 2000 attempts to obtain the code page from the hosting program. In this situation, the hosting program is Visual Basic Runtime (Msvbvm60.dll), which does not properly return a code page. Windows Media Player 6.4 cancels the request to open the file because the code page is required by any subsequent calls to the Urlmon.dll file (an ActiveX support file) to open the URL.

NOTE: Microsoft Windows NT 4.0, Microsoft Windows 95, Microsoft Windows 98, and Windows Me do not attempt to obtain the code page.



WORKAROUND
To work around this problem, use either of the following two methods:
 * Use another audio format or convert the .wav files to another audio format.
 * Embed the control in a browser program instead of in a Visual Basic program.



STATUS
Microsoft has confirmed that this is a problem in Windows Media Player 6.4.
