I saw some executables where there is just one executable and running it has pictures and other things. According to the source code they are called "resources". How may I do something similar, lets say I have a textfile, how may I put it into the executable when it compiles and then read it when the program executes?

Sorry my explanation isn't good, I don't know the proper terminology for this.

Thank you!

you want to read in the file contents? sure you can do that.. what do you want to do with the contents, though, print them? edit the file? look up fstream for a c++ class that is used to read/write from/to files
if this isnt what you meant please give more details

check libxml2

Here is an example (I see this usually in games), some simple games are just one executable, however they contain pictures and sound, there are no external files used. How is that done?[clearly sounds and pictures are somehow intergrated into the executable]

Thank you

i know in the old visual basic (version 6?) you could do this, i dont know of any other method.

i think its a better idea to seperate the code from other media, such as sounds and pictures. many popular professionally-developed games use external files to do this. do you really NEED to have it only one executable?

I don't need to, I just thought it was interesting.

ok this was found in koders.com
so to get a text file you specify the path and name and the read it.

Yeah, on Windows there is native support for resources (like program icons, or any other type of file). On Linux it's somewhat different. Basically, if you want to use a text file or a picture in a program you can simply write it into a variable. That can be complicated if you want to save binary data, but luckily there are some programs that can do that for you, such as the Qt Resource Compiler. I think it's practical to use resources if you are building an application that is meant to run on different operating systems, and you'd need to use different paths for pictures and other data you want to access. If you are only programming for Linux you shouldn't use it (you have to consider that a program is completely loaded into RAM when it is started, so if you have, say, a sound or movie file you want to use in your application, but you don't _always_ need it, it's the better choice to put it in a seperate file, so it only gets loaded when it's really needed).

And then there is open source. People like myself who are completely convinced of open source will always prefer seperate files since they can be used otherwise, too, or changed (without recompiling the program).
