• If you are using Microsoft Visual C++, create a new project workspace for a console application. Add the source file to the project.
• Set your options to include lib as one of the directories containing library files and include as one of the directories containing include files.
• Link to one of the following libraries:

• nsldap32v31b1.lib, the LDAP API import library
• nsldap32v31b1bc.lib, the LDAP API import library for Borland compilers (link to this library if you are using a Borland compiler or development environment)

Running the Sample Client

• The directory from which the application loaded.
• The current directory.
• The 32-bit Windows system directory. (In Windows 95, this directory is typically windows\system. In Windows NT, this directory is typically winnt\system32.)
• (Windows NT only) The 16-bit Windows system directory. (This directory is typically winnt\system.)
• The Windows directory.
• The directories listed in the PATH environment variable.
