  • Microsoft Software Development Kit (SDK) for Windows version 3.0

NOMMDLL is a file in the Microsoft Software Library that demonstrates how to determine whether the Multimedia Extensions to Microsoft Windows and its associated drivers are installed. NOMMDLL has two parts: the PLAYWAV application and the PLYSND dynamic-link library (DLL).

PLAYWAV indicates that the Multimedia Extensions are installed when its Sound menu option is available. When this menu item is grayed or unavailable, the Extensions are not installed. By default, PLAYWAV also determines if the sound driver is loaded. You can modify the code to look for other drivers if desired.

An application can use the PLYSND DLL to play sounds. The functions in PLYSND are useful to control the Media Control Interface (MCI).

Download NOMMDLL.EXE from the Microsoft Software Library (MSL) on the following services:

  • Microsoft Download Service (MSDL) 

          Dial (206) 936-6735 to connect to MSDL
      Download NOMMDLL.EXE (size: 22076 bytes)
  • Internet (anonymous FTP) 

          ftp ftp.microsoft.com
      Change to the \SOFTLIB\MSLFILES directory
      Get NOMMDLL.EXE (size: 22076 bytes)

Note: NOMMDLL uses the LASER.WAV file distributed with the Multimedia Extensions. To use NOMMDLL, verify that the MMDATA directory is listed in the MS-DOS PATH environment variable, or copy the LASER.WAV file into the same directory as NOMMDLL.EXE.
