This option enables you to access the CString class, which is very useful because IFilters typically do a lot of string manipulation. Click Finish to create your project, as shown in Figure 5. Figure 5. Select Support MFC in the Application Settings dialog box Use 64-bit Versions of I...
Make it a habit of closing any file stream, after it has been opened. When a stream is closed, any data in memory that was supposed to have been in the file is sent to the file before actually closing. The member function prototype to close fstream is: void close(); It returns void...
