// PLACE THE FOLLOWING TWO DIALOG COMPONENTS ON YOUR DESIGN WINDOW:
// TSaveDialog and TOpenDialog
// IT DOESN'T MATTER WHERE YOU PUT THEM.  THEY WILL NOT BE SEEN.

// PUT THIS WITH THE INCLUDES AT THE TOP:

#include <fstream.h>                              // YOU NEED TO TYPE THIS IN

// FUNCTIONS:

//---------------------------------------------------------------- SAVE STUFF
void saveStuff (void) {
   if (Form1->SaveDialog1->Execute()) {
      ofstream outfile(Form1->SaveDialog1->FileName.c_str());
      // assuming you're saving two arrays (cityX[] and cityY[]) of size "size":
      outfile << size << endl;	
      for (int i = 0; i < size; i++) {
           // use " " and/or endl as record separators:         
           outfile << cityX[i] << " " << cityY[i] << endl;
      }
      outfile.close();
   }
}

//---------------------------------------------------------------- OPEN STUFF
void openStuff (void) {
   if (Form1->OpenDialog1->Execute()) {
   ifstream infile(Form1->OpenDialog1->FileName.c_str());
   // assuming you are reading in values for two arrays as above.
   infile >> size;  
   for (int i = 0; i < size; i++) {
      infile >> cityX[i];
      infile >> cityY[i];
   }
   infile.close();
   }
