Found a max value on an array

Found a max value on an array

Postby Silvio.Falconi » Fri Mar 20, 2020 5:41 pm

When I insert a product I add an array

aadd(aColBtn,{nItem,ncolSer} )


Image


nItem is the number of Item and mColSer is the colum where I show the product

before to show the product I try to search the value of ncolSer on array aColBtn

If Len(aColBtn) >0
nColser:= ascan( aColBtn, {|e| e[1] = nItem})
If nColser=0
ncolSer:=200
Endif
else
ncolSer:=200
endif


the problem is the procedure found the nItem but take the first of the array with same nItem and not that having the max value

then I thinked to make another test
I when save on array aColBtn I must erase all records having the same nItem


adel( aColBtn, {|e|e[1] = nItem},.t.)

and I can save the current value

aadd(aColBtn,{nItem,ncolSer} )

but not run
because adel erase all records why ?

Make an ASort of the array by the column that contains the values to order and get the last element after ordering it.

I resolve with

nCheck:= ascan( aColBtn, {|e| e[1] = nItem})
IF nCheck >0
nColser:=aColBtn[nCheck][2]
nColser+=10
adel( aColBtn, ncheck,.t.)
else
nColser := 200
Endif
