This document describes a C++ sample program called Dictls32.exe that utilizes a File I/O API to display dictionary information from SPSS data files. It provides instructions on building the sample program using Microsoft Visual C++ and includes details on the constituent source code files that make up the program.

- 1. File I/O API - C++ Sample Program Overview Dictls32.exe (dictls16.exe in its 16 bit incarnation) is a C++ sample program which utilizes the File I/O API. It is a multiple document interface (MDI) application which displays the dictionary information from SPSS data files in one or more child windows. The user simply selects “Open” from the “File” menu to get a standard Open File dialog. If the selected file is an SPSS data file, its dictionary information is displayed in an edit control in a child window. The application is terminated by selecting “Exit” from the “File” menu. Building The sample program has been built with versions 1.5 (16 bit) and 4.0 (32 bit) of Microsoft Visual C++. Other compilers may work, but they have not been tested. In order to build the sample program, perform the following steps: 1. Copy all the files from the spssdkio_dllsmpl_cpp directory on the distribution disk to a directory on your hard disk. 2. Make sure spssdio.h is on the compiler’s search path - either by copying it to the directory containing the sample program or by modifying the INCLUDE environment variable. 3. Made sure spssio32.lib (spssio16.lib for a 16 bit build) is on the linker’s search path - either by copying the file to the directory containing the sample program or by modifying the LIB environment variable. 4. Use the nmake utility to build the application: nmake -f dictls32.mak DEBUG=1 For a 16 bit build, substitute dictls16.mak for dictls32.mak . Each of the makefiles recognizes two options which can either be set as environment variables or defined on the command line. The first option is “DEBUG”. If this symbol is defined (regardless of its value), the resulting executable will contain debug symbols. The default is not to include debug symbols. The second option is “STATICMFC ”. If this symbol is defined (regardless of its value), the resulting executable will contain statically-linked Microsoft Foundation Classes (MFC) and C Run-Time. The default is to use DLL-resident versions of MFC and the C Run-Time. The 32 bit makefile writes its intermediate and target files to a subdirectory named “32” while the 16 bit makefile writes the corresponding files to a subdirectory named “16”. In order to execute the resulting application, spssio32.dll (spssio16.dll for 16 bit builds) must be accessible at execution time. Integrated Development Environment Most users will opt to use Microsoft’s Integrated Development Environment (IDE) to build and debug an application. The sample application is amenable to being built in this fashion. Simply
- 2. File I/O API - C++ Sample Program open dictls32.mak by selecting “Open Workspace” from the “File” menu. You will have to select “Settings” on the “Build” menu to specify the name of the target file, the name of the required DLL, and the debug build command line. If you are using the 16 bit IDE, open dictls16.mak via the “Open” item on the “Project” menu. Here, the name of the target file and the debug build command line are specified via the “Project” item on the “Options” menu, and the name of the required DLL is specified via the “Debug” item on the “Options” menu.
