You don't actually delete that because it's a visual aid. What you can do is disable that particular visual aid.

What you want to do is go to EDIT -> ADVANCED -> View White Space to toggle that aid on or off. There's a couple of other aids you might want to toggle too.

It's like if you were trying to jump steps.

What library are you using to interact with an SQL database? If your answer is none... Then you need to learn how to link and use libraries with your compiler. If there's a lib or API you're using. What you need is there. Read the documentation!

Ok, here's some links you should check out and below, a simple example.

Try it out, make changes, read the documentation and enjoy the endless possibilities it provides.
rand() function
http://www.cplusplus.com/reference/clibrary/cstdlib/rand/
srand() function (generates a random seed)
http://www.cplusplus.com/reference/clibrary/cstdlib/srand/
Time library from c where we can get the time_t time ( time_t * timer ); function
http://www.cplusplus.com/reference/clibrary/ctime/
ASCII codes:
http://es.wikipedia.org/wiki/ASCII

#include <iostream>
//ctime is used to set the random seed.
#include <ctime> 

int main(int argc, char** argv)
{
  using namespace std;
  /*Initializes de seed to use the current time
  so that the numbers are different each run 
  of the application*/
  srand((unsigned)time(NULL));
  
  /*Check the ASCII code values.
  Lowercase goes from a = 97-> z=122 
  Uppercase goes from A = 65 -> Z=90 */

  //rand() returns a number between 0 and RANDMAX
  
  //arbitrarily, I decided to show 40 random letters
  for(int iii=0;iii<40;iii++)
  {
    char letter = rand()%25 + 65;
    cout<<letter<<" ";
  }

  /*
  Exercise 1: change 65 to 'A' 
  Exercise 2: change 65 to 'a'
  3: Use a number as a seed (instead of the time(NULL) function) 
  and you'll always get the same succession of random numbers"
  4: Test and research 
  */
}

Good luck and remember, be specific when you ask for help and show what you have done so far.
