You may use FldSetText but the text pointer must be static (read the API
reference). Or you can copy the text into the field text handle.
Here's my own FldCopyText procedure:
// ** FldCopyText ***
// Copy string contents to text field
// -> form : calling form
// -> fieldID : field ID
// -> text : text to write
// returns the field
FieldPtr FldCopyText( FormPtr form, UInt16 fieldID, Char *text )
{
FieldPtr field;
MemHandle handle, oldHandle = NULL;
Char number[ maxStrIToALen ], line[ maxStrIToALen ];
Err error;
field = ( FieldPtr ) FrmGetObjectPtrFromID( form, fieldID );
oldHandle = FldGetTextHandle( field );
if ( ( text != NULL ) && ( text[ 0 ] != chrNull ) ) // if there
is any text to copy
{
handle = MemHandleNew( StrLen( text ) + 1 ); // create
new text handle for field
if ( handle == NULL )
FrmCustomAlert( OutOfMemoryAlert, __FUNCTION__, StrIToA( line,
__LINE__), StrIToA( number, StrLen( text ) + 1 ) );
else
{ // copy string
content
StrCopy( ( Char * ) MemHandleLock( handle ), text );
error = MemHandleUnlock( handle );
FldSetTextHandle( field, handle );
}
}
else if ( oldHandle != NULL ) // new text
is empty => clear handle
FldSetTextHandle( field, NULL );
if ( oldHandle != NULL )
error = MemHandleFree( oldHandle );
return field;
}
