A lot of people on here want to use dgdk functions. lol i actually like fstream good job

Although doesn't fstream have a getline function? and does it need to use the string type? because everything in dgdk uses char*'s

So just use .c_str(), std::string makes your life a lot easier so you should use it for pretty much all of your strings anyway.

dbStr() is different.

dbStr() is like sprintf. it takes a value and converts it to a string. what he is talking about is a string, but not like a char* string(which is called a c string) it's a class called string. One of it's functions is c_str() which returns a c string( a char*) that can be used with dark GDK stuff.

The string class has very useful things like copy and operators like + and -, and there are operators for equality testing. Unlike a c string when you type this:

if(myString1 == myString2)

it will test if the value of the strings are equal, not the pointers. it functions much like a dbp string.

Standart-strings and fstream save so much trouble and have lots of useful functions! I wouldn't do any DGDK app without them these days
For me, they're two of the reasons why DarkGDK is superior to DBPro...

Now the plot thickens, the fps decreases, and the awesomeness goes through the roof.

He knows, he said "That and dbStr() save so much time!", implying that both are boons.

Though I personally wouldn't go near dbStr() with a barge pole, or generally any of the GDK string functions unless you have to; they all dynamically allocate memory which means you have to free it yourself, which a lot of people don't realise plus it's easy to forget, and makes it so you can't use dbStr() safely in certain situations(like passing it to a function). If you must use such functions, at least wrap it so you only have to handle the deallocation once. GDK's lack of const-correctness is also annoying as you have to keep casting to stupid types whenever you need to pass a string, thus I usually end up wrapping any string related functions and generally everything.

I believe the solution has nothing to do with your code but your project settings. I forget exactly what, try changing your character set to Not Set and your use of MFc to Use Standard Windows Libraries

That's the default setting. it makes no sense. simple solution would be to create a File I/O Dll.

For fstream be sure you include iostream, and fstream and then use:

using namespace std;


fstream has a getline function.

google the linker errors(the new and delete ones)

Try going to Project->Project Properties...->[+]Configuration Settings->[+]C/C++->Code Generation and change the runtime library to /MT NOT /MTd
