[Gambas-user] Substitute of the object names

[Biro Zoltan]

Thank you Rolf to helping me.
Please take a look on the folowing piece of code:
(I never used array of texboxes, but I think is something like I did
here)

PUBLIC SUB filltheboxes()

 DIM x AS String[20]
 DIM y[20] AS TextBox
 DIM i AS Short

 x[0] = "1"
 x[1] = "2"
 x[2] = "3"
 x[3] = "4"
 x[4] = "5"
 x[5] = "6"
 x[6] = "7"
 x[7] = "8"
 x[8] = "9"
 x[9] = "10"
 x[10] = "11"
 x[11] = "12"
 x[12] = "13"
 x[13] = "14"
 x[14] = "15"
 x[15] = "16"
 x[16] = "17"
 x[17] = "18"
 x[18] = "19"
 x[19] = "20"
 
 i = 0
 FOR i = 0 TO 19
  y[i].text = x[i]
 NEXT 

END

Why this code return a "Null object" error code??

I hope to can be solved in Gambas2 more simply the substitute problem. I
used before FoxPro for Windows. Here is simple:

i=1
for i=1 to 20
  boxname="n"+str(i)
  &boxname.text=" enithyng "
endfor
Is something in Gambas2 similar for &boxname.text, like in Foxpro?

For me the second variant seems to be more simply, but please explain me
why I have "Null object" error on the gambas2 code
