MKTYPLIB.EXE is a tool that creates type libraries from Object Description Language (ODL) files.

To create a type library:

  1. Create a command window.
    From the Start menu, select Programs.
    Select MS-DOS Prompt or Command Prompt, depending on the version of the operating system.
  2. In the command window, include the Developer Studio BIN directory in the path.
    This directory is c:\msdev\BIN, where c:\msdev is the directory where you installed Visual J++. 
       set path=%path%;c:\msdev\bin
  3. In the command window, navigate to the sample directory.
  4. In the command window, run MkTypLib.
