Thread: How to make a VERY basic interface

this is taken from one of my projects when from when i was studying.

(note : It will not compile)

this is basicly what you can do.
this is the intro for my banking system. It displays a rotating yin-yang, the time(updates every second) abd a message that flickers. both of these three items all refreshes at a different time

Code:

void Driver::intro()
{
   int gd,gm;
   int yrad  = 100;
   int xrad  = 100;
   int flag1 = 0;
   int flag2 = 0;
   int counter = 0,counter2 = 0;
   float rad;
   char* text = "Press any key to continue";
   void far* buffer;
   void far* buffTime;
   void far* buffContinue;
   SysInfo info;

   rad=12.5;
   detectgraph(&gd,&gm);    //initgrpah
   initgraph(&gd,&gm,"");
   //get memory for buffers
   buffer = farmalloc(imagesize(1,1,205,205));
   buffTime = farmalloc(imagesize(1,1,100,50));
   buffContinue = farmalloc(imagesize(1,1,400,100));
   //getimage for buffers
   getimage(1,1,205,205,buffer);
   getimage(1,1,100,50,buffTime);
   settextstyle(1,0,2);
   outtextxy(320-(textwidth(text)/2),420,text); //prints message
   getimage(320-(textwidth(text)/2),420,320+textwidth(text)/2,
   			420+textheight("H")*1.5,buffContinue);
   setcolor(GREEN);
   outtextxy(320-(textwidth("CopyRight 2001, Ernst Bleeker")/2),10,
   			"CopyRight 2001, Ernst Bleeker");
   settextstyle(1,0,5);
   setcolor(BLUE);
   introRead();   //calls the inroread function
   setcolor(WHITE);
   settextstyle(1,0,3);
   setcolor(RED);
   info.dateG(465,150);    //gets the date
   if (gd == 9)
   {
      outtextxy(490-textheight("Video Mode :"),300,"Video Mode :");
   	switch(gm)
      {
      	case 0: outtextxy(530-(textwidth("640x200x16")/2)+15,340,"640x200x16");

      }
   }
   else

   }
   info.time(495,240);	//get the time
