keypad problem??

[mir_as82]

HI
i m new on CCS forum.i have tried to make a project with keypad many times but i havent achieved it.i use kbd.c file.and i use pic16f877.when i press any key so i want to show this key on lcd.
PORTB 1-2-3-4 pins are rows
PORTB 5-6-7 pins are columns.

and i added pull up resistor to columns.

and i use lcd port PORTD.Please anyone help me.my codes are:
#include "C:\Users\keyexample.h"
#define use_portd_lcd TRUE
#include <LCD.C>
#include <kbd.c>


void main()
{
char key;
setup_adc_ports(NO_ANALOGS);
setup_adc(ADC_OFF);
setup_psp(PSP_DISABLED);
setup_spi(SPI_SS_DISABLED);
setup_timer_0(RTCC_INTERNAL|RTCC_DIV_1);
setup_timer_1(T1_DISABLED);
setup_timer_2(T2_DISABLED,0,1);
lcd_init();

for(;;)
{
key=kbd_getc();
lcd_gotoxy(1,1);
lcd_putc(key);
}
}

i cant do it:( .why i cant do it.i m not really so ameteur.
will i connect columns to portb bits directly?i use proteus-isis simulation programme.i tried your notifications but still cant work.there is not problem in lcd cause i write it character.

Lately this is a recursive subject in this forum.
Proteus like other tools is a virtual simulator that generates a good approach
with the real world with no need to see a simple cable. The use of this type of tools
has the disadvantage that if it does not work as expected, is very difficult to offer aid
because 99% of the error possibilities would be given by the selected operating
parameters and other simulator setups.
The helps in hardware related to CCS Complier running in PIC MCU´s that this forum
can offer is based on the skills and experience of most of us with the "real"
hardware, that give us the possibility of being able to make electrical determinations
of voltage levels and other measurements in the real -non virtual- world.

Concretely, you are using some programs of the CCS package that had been tested
extensively and whose operation is guaranteed, but running in a simulator environment
they do not behave as expected.
I strongly suggest you to redirect this question to a forum related to Proteus simulator.
