[Gambas-user] how to write text in indexed list of labels

An alternative approach, which is particularly useful if the labels are 
dynamically placed on the form,  would be to use a global array of labels:

In the globals area of the form class:

     Private theArrayOfLabels as Collection

In the form setup method (say form_open):

     theArrayOfLabels = New Label[]
     Dim lbl as Label

     For each index as Integer = 0 to 199
         lbl = new Label(parent)  'parent could be Me or some other 
         'code to setup the new label (initial text, font, foreground, 
width  etc)
         'you don't need to set the name

Finally where you reset the label text:

     theArrayofLabels[index].Text = "new text"

Instead of an array of labels, you could use a collection of labels, 
with the key being the individual label's name.
