Hi all, I'm pretty new to the linux (Fedora Core 2) environment and hope that this question is suitable for this mailing list. I currently have a program written in C++ which is used to automate Microsoft Excel by writing out data to the spreadsheet and then updating about 10 charts based on this data in the spreadsheet. I'm not sure if any of you are familiar with the Microsoft environment but the program is developed in Visual Studio 6 and is based on the Microsoft Foundation Classes. I have Open Office installed on my linux machine and I know it is possible to open / read / write an Excel file using Open Office Calc and to create charts manually. What I'm wondering is if it is possible to automate the process of writing to and updating the charts in an Excel file in C / C++ code so that it will work in the same way as the windows program I already have and where could I get documentation on how to do this. If its not possible to do this with Excel files (although I would prefer to use Excel files), is it possible to automate the process using the standard Calc spreadsheet file format, .sxc and where could I get documentation on how to do this. Alternatively, would there be any way to port the program I already have on Windows to linux.
