Clearing the Contents of a Field or Scrollable Region Row

You can clear the contents of a data field, memo field, or a field in a scrollable region. Additionally, a function is provided to clear all the fields in one row of a scrollable region.

To clear the contents of a data field or memo field, call the field blank function, fld_blank():

void fld_blank(fld_or_memop, dfmp)

FIELDPTR fld_or_memop;

/* Pointer to field or memo to update

*/

DFORMPTR dfmp;

/* Form being processed

*/

To clear the contents of a field in a scrollable region, call the scrollable region field blank function, srf_blank():

void srf_blank(data_row, data_col, srp)

int data_row;

/* Data row of scrollable region

*/

int data_col;

/* Data column of scrollable region

*/

SRPTR srp;

/* Scrollable region

*/

To clear all the fields in one row of a scrollable region, use the scrollable region blank row function, sr_rowblank():

void sr_rowblank(data_row, srp)

int data_row;

/* Data row of scrollable region

*/

SRPTR srp;

/* Scrollable region

*/
