File I/O API - C++ Sample Program 04 Feb 03 Overview Dictls32.exe 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 version 6.0 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: Copy all the files from the SPSS\Developer\io_dll\smpl_cpp directory on the distribution disk to a directory on your hard disk. 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. Made sure spssio32.lib 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. Use the nmake utility to build the application: nmake -f dictls32.mak DEBUG=1 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 makefile writes its intermediate and target files to a subdirectory named “32”. In order to e
