strange behavior of a TGet

[Silvio.Falconi]

I have 3 numeric get controls

when I insert a number in the first tget it would become the third update because it is a clause of the bchange and it performs a calculation

but if I delete the number in the first get it does not execute the bchange for the second time,

is normal or there is something wrong because in my opinion when I update a get automatically the third should be updated




I had never noticed this problem, today trying the program I realized that there was something unusual
if I activate the bchange I cannot enter any number in the get
here the sample test

Code: Select all  Expand view  RUN

Now I correct with

Code: Select all  Expand view  RUN

  @ 96, 10  Say "Costo :" SIZE 90,10 PIXEL OF oDlgMod
  @ 94, 75 GET aGet[7] VAR nCosto   OF oDlgMod SIZE 60, 12 ;
            PIXEL PICTURE  '@ €99,999.99' RIGHT FONT oFont UPDATE ;
             ON CHANGE ( aGet[7]:assign(), ;
                         Calcolo_tariffa(nCosto,nSconto,@nTotale,aGet))


  @ 96, 145  Say "Sconto :" SIZE 90,10 PIXEL OF oDlgMod
  @ 94, 175 GET aGet[8] VAR nsconto   OF oDlgMod SIZE 60, 12 ;
            PIXEL PICTURE  '@ €99,999.99' RIGHT FONT oFont UPDATE  ;
            ON CHANGE ( aGet[8]:assign(), ;
                         Calcolo_tariffa(nCosto,nSconto,@nTotale,aGet))

 

now it seems to work but it is a little weird behavior this problem never happened
