Some questions...

[Magus_Stragus]

Hey there. Again, I come with more questions.
1. I need to create an Internet application (this is, like a server accessible via Internet). Is there a library for this that also give me support with Irrlicht?
2. Can Irrlicht export to MS Excel datasheets?
3. More than am Irrlicht question, this is a general programming question. How do I do to open an application and run it using another program to do it?

Thanks in advance for the help.

1) there are various network libraries you can use, check out raknet for one.

2) Probably, you just need to know what the excel format is (how the file is arranged etc) and write out a file in that format, you can do that from any application, C++ or otherwise. The hard bit could be finding out how excel files are structured... that might not be freely available information.

3) No idea about this one but i'm sure goole will tell you

Hey there. Again, I come with more questions.
1. I need to create an Internet application (this is, like a server accessible via Internet). Is there a library for this that also give me support with Irrlicht?

There's an Irrlicht specific network library called IrrNet that might suit your purposes.

If you're looking for a general purpose network library, then I'd recommend Raknet. It will have a steeper learning curve than IrrNet to get a basic app running (since it's not tailored to Irrlicht), but is more fully featured. I'd go with Raknet, since deciding what data to send and when to send it is a far bigger problem than simply packing some floats into a network packet.

2. Can Irrlicht export to MS Excel datasheets?

MS Excel can open Comma Separated Values files, which are trivially easy to create from any data using fprintf(), or a library.

3. More than am Irrlicht question, this is a general programming question. How do I do to open an application and run it using another program to do it?

The C stdlib system() call can be used to run any arbitrary application.

There are also platform dependent methods. On MS Windows, you can use CreateProcess(), for example.

Heeeehahahaahah, "just". Welcome to my private hell.

that might not be freely available information.

Astonishingly, it is available, but you'll need to pass a sanity check before reading it. Also, the specs are more... guidelines... than rules. Unless you really need to write out an .xls binary file, then it's CSV for the win all the way.

1.- Internet application? What do you mean? A generic client/server or maybe a client that conect to webservices or...? For generic you should try Racknet

2.- MS Excel: Comma/tab separated values, XML, Apache POI or try looking for info about "spreadsheet ML"

Thanks for all the help. I'll try out RakNet, and I will also try to do the exporting using commas and fprint.
