Hi. guys. got some things here that you might be able to help me out. I am able to get adc going by measuring a voltage divider, able to send it to lcd and get it to the gui i created in c#. Here is the problem. as the adc is updating, so is the gui keeps getting data but its continiuous, example is voltage reading = 3.7. i am getting in gui, 373737373737. Also how to put the dot (.) between the numbers? any suggestion is welcome. I have the code here.

Code:
#include <pic.h>		// standard pic header file
#include <stdio.h>
#include <htc.h>
#include	<conio.h>
#include "usart.h"//Adapted from http://electronics-diy.com
#include <string.h>		// string function header file

#include "delay.h"
#include "delay.c"
#include "lcd.h"
#include "lcd.c"//Rs-RD4, EN-RD5, RD0-RD3 -- pin 11 -14 of LCD

// Configuration Fuses
#if defined(_16F877A)
#warning PIC16F877A Selected
	__CONFIG(0x3F61);
#else
#error Unsupported PICmicro MCU Selected
#endif
// Global Variables

#define LED1	RB6		//LED connects to port B
#define LED2	RB7		//LED connects to port B

#define LEDS_8 PORTB
#define LEDS_2 PORTC

void get_adc ();

void get_adc()
{
//8bit data-type variables
unsigned char x;	//ADC low byte
unsigned char y;	//ADC high byte
unsigned long press,calc,w, z; 
unsigned long inter, deci;
	
	DelayMs (1);
	//Start a2d conversion
	//Set GO bit (ADCON0=ADCON0|1;)
	GODONE=1;
	//wait end-of-conversion (conversion complete)
	while(GODONE==1);
	
	x=ADRESL; //store low byte
	y=ADRESH;	//store high byte
	w=(256*y+x); //multiply the signal together
					//*256.0 is to get the overall stage
press = w*500/1023 ;
inter =  (press/100)%10;
deci = (press/10)%10 ;

lcd_goto (0x0b);
lcd_putch (inter | 0x30 );
lcd_goto (0x0c);				// move cursor to Row 0 Colum 11
lcd_puts(".");					//display “.” (Decimal point)
lcd_goto (0x0D);
lcd_putch ( deci| 0x30);
lcd_goto (0x0F);
lcd_putch ( 0x56 );// letter V for voltage

if (RCIF) {
	z = (inter |0x30);
	TXREG = z;

TXREG = (0x2E);
calc = (deci|0x30);
TXREG = calc;
DelayMs (100);
RCIF =0;
TXIF = 0;

}
}
