Ok, I have a question now for real I want to provide a list of strings to hold player profile names for selection. I had two ideas for this. One was to use std::string and just provide a list of strings. This doesn't work with DarkGDK; apparently there are library conflicts? So my other idea was to use a pointer to a pointer, char **. Hahaha yeah that didn't work either. It keeps causing heap corruptions.



This is a very crude example of what I am trying to do. If anyone has a suggestion as how to implement this sort of functionality I would appreciate it!!!

Just use a double char array or vector, and set the profile name input to allow a certain length?

Hmmm... interesting. Yeah I guess I COULD do that. Haha I always over-complicate things when it comes to handling strings cuz I LOVE dynamic strings for some reason. It would be alot simpler code. Yep going with that solution until/unless another comes along. Thanks!

In the original question it was asked if you can use the standard C++ library with Dark GDK, such as std::string, etc. Can you?

Haha nevermind. I found my problem. Allocating only a byte for a pointer does not work in a 32-bit system. Or a 16-bit system for that matter lol. That was crashing my code. All fixed!!! And working perfectly I might add...

No problem and i know what you mean. I'm not too keen on chars for strings either, haha. I prefer strings a whole lot more

You can use std::string in DarkGDK, you just have to set your project to "/MT Multi-Threaded" in "Project Settings / C++ / Code Generation"

Thanks Bigglesworth. I was too seeking an answer to that question. I didn't want to change any of the project options and have my code fail so I let it be Now I can use the string library on my next bit of code, though I must say that using char *s instead of strings will keep the executable files smaller. I don't plan on having a huge executable but my engine will be big enough without the bloat of std::string on top of that!!!
