For each in Me.Controls Part 2

Chaosian, shall I, in my form_Load() do this:

For Each ctrl As Control In Me.Controls
If TypeOf (ctrl) Is Button Then
myButtons.Add(ctrl.Name, Nothing)
ElseIf TypeOf (ctrl) Is Label Then
myLabels.Add(ctrl.Name, Nothing)
End If
Next

Something like that, to put all my controls in my Dictionnary tables
Not sure what to put in the value parameter also

apresto

Hi PhilippeRenaud,

the value parameter is what is displayed to the user. Are myButtons and myLabels Hashtable?

Yes

I did :

Dim myButtons As Dictionary(Of String, Button)
Dim myLabels As Dictionary(Of String, Label)

Also, i am getting an error here:
myLabels.Add(ctrl.Name, ctrl)

not sure why, let me try again
