Program Example of a Virtual Data Form

Designer: The tutorial program dvfm_basic.c uses a virtual form created in the Designer. You should compile, link, and run this program to understand how a virtual form looks compared to a regular form.

Code: The following tutorial program, vfm_basic.c, is similar to the code presented in Chapter 6, "Writing Forms in Code." The only difference is that a virtual form is defined. The form window in this example is smaller than the whole form. You should compile, link, and run this program to understand how a virtual data form looks compared to a regular form.

#include <vv_str.h>
 
/* Include string field header
 
*/
 
#include <vv_main.h>












/* Include main







*/















int main(void)









 

 












{




 

 












    DFORMPTR dfmp;







/* Declare pointer to form







*/















    UCHAR *lastname, *phone_no;












/* Declare type of data variables







*/















    vv_init();












/* Initialize Vermont Views







*/















    /* Allocate and initialize data variables                   

    lastname = mem_stblank(15);

    phone_no = mem_stblank(12);












*/















    /* Allocate & initialize form                            

    dfmp = fm_vdef(8, 0, 4, 80, LNORMAL, BDR_DLNP, 7, 80);












*/















    /* Define last name field                            

    fld_def(3, 1, "Last Name:     ", FADJACENT, "!XXXXXXXXXXXXXX",

            F_STRING, lastname, dfmp);












*/















    /* Define phone number field                            

    fld_def(5, 1, "Phone number:  ", FADJACENT, "(UUU)UUU-UUUU", 

            F_STRING, phone_no, dfmp);












*/















    fm_proc(0, dfmp);












/* Process example form  







*/















    /* Collect the data from the data variables (not shown)












*/















    fm_free(dfmp);












/* Free memory for form







*/















    /* Free memory allocated for data variables 







*/















    mem_free(lastname);




 

 












    mem_free(phone_no);




 

 












    vv_exit();




 

 












    return(0);
