[phd.khosravi]

hi every one

Sub Globals
    'These global variables will be redeclared each time the activity is created.
    'These variables can only be accessed from this module.
    Dim Button(9) As Button
   
End Sub

Sub Activity_Create(FirstTime As Boolean)
    'Do not forget to load the layout file created with the visual designer. For example:

   
    For i = 1 To 8
    Button(i).Initialize("button"&i)
    Activity.AddView(Button(i),5%x,i*11%y,65%x,10%y)
    Button(i).Text="number"&i
    Button(i).Visible=False
    Next
   
End Sub

how can i use a code that One of the keys to the unseen
i mean like button3,button5,button7 be visible when u start program

For i = 1 To 8
  Button(i).Initialize("button"&i)
  Activity.AddView(Button(i),5%x,i*11%y,65%x,10%y)
  Button(i).Text="number"&i
  Button(i).Visible=False
  if i = 3 then Button(i).Visible=true
  if i = 5 then Button(i).Visible=true
  if i = 7 then Button(i).Visible=true
Next

thank you dear Don just want to know can i use code like this :
if i = i+3 then Button(i).Visible=true
?

 

[DonManfred]

"i" cannot be "i+3". So it´s always false

 

[phd.khosravi]

so there is not any way to use just a code to visible many buttons ? or should i just do like that u told me dear

See this tutorial: Tick-Tack-Toe: working with arrays of views

 

[Beja]

  if i = 3 then Button(i).Visible=true
  if i = 5 then Button(i).Visible=true
  if i = 7 then Button(i).Visible=true

or just:

Button(3).Visible=true
Button(5).Visible=true
Button(7).Visible=true

another way:
If the buttons to show are in sequence (like 4,5,6,7) then you can use for...next loop
if the numbers are in geometric or arithmetic progression, then you can also use for...next loop with some additional efforts.
3,5,7 are in arithmetic progression (odds) but since the array is only 3 then you can just use the above example because you wouldn't save any code lines or time.
