Dark GDK / dbtext and strings

I am a newbie at c++. I'm having a crack at it after programming basic for many years (using DB Pro for the last good while).

So. I thought I'd start with something simple. Load an object, put it at 0,0,0 and look at it. Well, it loads (or at least compiles), but I couldn't see it. So I thought I would have a look at a command similar to objectvisible in DB Pro.

So, now I get to the bit on my programmers checklist I thought wouldn't take more than an hour to solve - print text to the screen. Numbers are fine - convert a number to a string and print to the screen - oh oh, you need to solve world peace and then move on to the harder subject of strings in c++.

OK, so they are arrays and pointers - or some of them are, or seem to be.

I am coming from the world of basic. I have read multiple help pages, but DBtext is a command for this forum.

I'm not asking for someone to go to the trouble of explaining all of c++ string to me, just common errors
mine is : error C2664: 'dbText' : cannot convert parameter 3 from 'std::string' to 'char *'

-Can anyone give any quick advice for what DBtext is expecting - what will work and what won't?
-Also it seems that there are some really bad ways to program strings - is there a quick way of describing how it should be done, or a link to some reading material?
-If anyone has the time: why was it so so simple in DPPro to make strings, append them, and print them? It presumably just took all this away from the user?

Much thanks for any help. I can't solve world peace, but I'm determined to get my head around this.

'std::string' is an C++ string object. 'char*' is a c string.

See here for more information and usage example:

To make things simple, I prefer to use this method:
Make a global

Then whenever I need to put some data on the screen

You don't need to solve for world peace, you just need to solve your piece of the world.

The fastest code is the code never written.
