a DBCOMBO review

[Marcelo Via Giglio]

Hello everyone,

I am leaving a modification of DBCOMBO class that adapts it to the last source I have from fivewin, there are sure to be some details, but it may be of interest

The modifications, the following options were added to dbcombo.ch:

[ <noblank: NOBLANK> ] ;
[ ORDER <order> ] ;
[ FOR <uCond> ] ;
[ TOOLTIP <cToolTip>] ;

NOBLANK : for the combo not to start with a blank value, it starts with the first value in the list
ORDER : to use an index when filling the combo, in this case it is a TAG of an index
FOR : is for the data to be filled accoring a condition e.g. field->state = 'IL'
TOOLTIP : no need to explain

Important! The specification of ITEMFIELD and LISTITEM can be not only the name of the field, but also an expression
for example " trim(first) + ' ' + trim(last) "
"alltrim(str(id))" this way we can select numeric fields

I leave the source and example, the example is in the dbcombo.prg source
