hi there,

i have a problem using ncurses. i attached the source code with this email.
this program displays two text fields. my problem occurs when i add this,
`char buff[256];` after the declaration, `int ch;`.
after adding the character array declaration, the text fields won't 
display anymore.
any ideas?

-earl-.

#include <form.h>


int main(void)
{
    int ch;

    FORM *formp;
    FIELD *fields[2];

    initscr();
    cbreak();
    noecho();
    keypad(stdscr, TRUE);

    fields[0] = new_field(1, 32, 4, 18, 0, 0);
    fields[1] = new_field(4, 32, 6, 18, 0, 0);

    set_field_back(fields[0], A_STANDOUT);
    field_opts_off(fields[0], O_AUTOSKIP); 

    set_field_back(fields[1], A_STANDOUT);
    field_opts_off(fields[1], O_AUTOSKIP);

    formp = new_form(fields);
    post_form(formp);
    refresh();

    mvprintw(4, 5, "IP Address:");
    mvprintw(6, 5, "Message:");
    move(4, 18);
    refresh();

    while( (ch = getch()) != KEY_F(1) )
    {
       switch(ch)
       {
          case KEY_DOWN: 
               form_driver(formp, REQ_NEXT_FIELD);
               form_driver(formp, REQ_END_LINE); 
               break;

          case KEY_UP:

               form_driver(formp, REQ_END_LINE); 
               break;

          default:

               break;

    free_field(fields[0]);
    free_field(fields[1]);

Hey Earl!

try
FIELD *fields[3];
and
fields[2] = NULL;

I wondered how should new_form know when the array ends..

regards,

Markus
