Ok, this is starting to get fustrating.



...returns an error:

error C2664: 'dbText' : cannot convert parameter 3 from 'const char *' to 'char *'

I've tried for a while now to get simple data types like strings working! First I was using c style strings, but they were annoying to organize, now I'm the std::string type and it's even more confusing.

Sorry if this query has an obvious answer, I am still getting to know C++.

EDIT: BTW, the inputData [ ] array is previously declared like so:
string inputData [ 100 ] ;

Persist and you will succeed.

You need to explicitly cast it to a char*

i.e.

dbText ( xPos + 8 , yPos - 8 , (char*)textDisplay.c_str ( ) ) ;

Much good work is lost for the lack of a little more.

I hope that dbText does not modify the the (char *) value, otherwise bad things will happen.

This is a bad implementation of the parameters to dbText unfortunatly; as it should really be declared 'const.'

I cheat... I make a char[whatever] and then pass the address

dbText(&MyChar).....

but everywhere else I do things much cleaner... I DONT use that routine much though.
