When you're stuck on a tutorial, you can ask for help of course.

Nah I just meant to say that if you're sure that you'll only use it on your system, why not use those compiler specific functions? I think it's overkill to make basically everything you create cross...

I'm more of a newb but feeling cocky as always:

Don't AVOID compiler specific functions, but be sure to find a cross-compiler way to do it as well, as in: find it, use it a couple of time,...

Not in any imaginable way if you ask me. Like I said, a pointer to an array of pointers (an array of "arrays") resembles a 2D array. Unless you want that, there's no use for a double pointer.

You...

It is only a pointer, don't worry. It's a pointer that points to pointers.

The struct declaration indeed only reserves one pointer, not an array or anything.

However, I guess you want to have...

hehe, you should access sc.students then, not students. ;)

#
students = malloc(sizeof(struct student));
#
strcpy(students[0]->name, "jack");

I might have missed it, but of what type is "students"? It seems to be an int, since the declaration is lacking...

Regression? Don't you mean iteration? Could be wrong, but according to wiki (I had to look it up) regression is bug-related, not loop related like recursion.

If you mean iteration, then that is...

Define "doing the same thing".

I can drive to the store on my bike and in my car, doing 2 different things. Or I can say that I'm going to the store, doing one thing, in 2 ways.

C compilers...

I just meant to say he's trying to create a C program I guess, using a C++ compiler since only a C++ compiler will throw that error. Nothing more.

"cannot convert from" is a C++ (and in general, OOP) only error afaik.

You're getting C++ errors. C++ is a lot stricter. Try using a C compiler. ;)

Shouldn't matter in what language your DLL is made, I think you need to figure out how to thread in RealBasic and call the functions from your realbasic program.

WndProc is a callback function. I don't call it.

So, declare a static struct in WndProc and pass a pointer... That makes sense. Thanks.

I'm writing this windows app and I can't figure out how to let the user manipulate data (in a function called by WndProc) without using globals. Do you think it's better to use one global...

Well, I tend to use them when it saves me adding numerous parameters to some functions. I think you can use global variables, but you should at least limit most of them to one source file with the...

Just open it for reading and writing. Write to it, read from it.

What's the problem? You can find how fopen works for reading and writing on numerous C reference sites.

Open it for reading and writing?
