Hi All

I am trying to create a shared Dynamic Array in Freebasic.
It seems a bit different than Powerbasic.

In PB I used to do this:

Global MYlabelsarray()As String
This was declared outside of a procedure, then in a function I would assign values:

Dim MYlabelsarray (1 To myqty&)As String

I tried using COMMON shared MYlabelsarray() as string and redim it inside a procedure.

This works fine between all functions for e.g. Form1, but how do I make it accessable over the entire project?
If i use the same request e.g. print myarray(1) in form2 etc, it tells me the variable has not been declared.

How would you do this in Freebasic?

Here is how you can do it:

dim shared MYlabelsarray() as string

function myfunction1() as long
   dim as long myqty = 100
   redim MYlabelsarray (1 To myqty) As String

   ' or use redim preserve to not destroy existing data in the array
   ' redim preserve MYlabelsarray (1 To myqty) As String
   for i as long = 1 to myqty
      MYlabelsarray(i) = "Label " & i

   function = 0
end function

function myfunction2() as long
   ' Display the global array strings
   for i as long = lbound(MYlabelsarray) to ubound(MYlabelsarray)
      print MYlabelsarray(i)

   function = 0
end function


print "Press any key to exit..."

Hi Paul

Thank you, that was what i did eventually.
It works fine in all the procedures under form1, but as soon as i try and refer to the array for procedures on another form, I am getting that "variable not declared".

So i just moved all the functions that would use the Array to form1. -Problem solved.

I wonder if it doesn't have something to do with the fact that i am using child forms on a tab-control?

But, problem solved.

Thanks a million.
