For example, on a computer running Microsoft® Windows NT® Server/Windows 2000 Server, Windows NT Workstation/Windows 2000 Professional, or Microsoft Windows® 95/98, the application either links to the Driver Manager library or calls LoadLibrary to load the Driver Manager DLL.The next task, which must be done before an application can call any other ODBC function, is to initialize the ODBC environment and allocate an environment handle, as follows: The application declares a variable of type SQLHENV. It then calls SQLAllocHandle and passes the address of this variable and the SQL_HANDLE_ENV option. For example: Copy SQLHENV henv1; SQLAllocHandle(SQL_HANDLE_ENV, SQL_NULL_HANDLE, &henv1); The Driver Manager allocates a structure in which to store information about the environment, and returns the environment hand
