Exporting a Spreadsheet as Text in C++
This example demonstrates launching an instance of Statistica, opening a spreadsheet, and exporting it as text.
//BEGIN Windows Specific inclusions #include <windows.h> #include <comdef.h> //needed for COM /*The "#import" directive imports the class library information of the specified file. In this case, the file "statist.exe" will give us access to the Statistica interface and its documents' library. You will either need to include this file in your project directory, or hard code the full path to the file in the #import directive. Lastly, note that "#import" is a Visual C++ compiler specific directive; if you are using a different compiler, then please consult your compiler's documentation on how to import a COM interface.*/
