can I declare an array of overlays ??

You saved my life, Thanx man thanks alot and sorry for the trouble

:D

Did you actually place the labels directly on the form or are they inside one (or more) of the panels?  If they are then you'll need to index the panel's controls collection rather than the form's collection. For example, if a label was on Panel1:

Dim l As Label = DirectCast(Panel1.Controls("Label" & j.ToString()), Label)

thanx alot for your help you saved me, every thing worked fine :D except the label decleration

it gives me a troubleshooting exception!! is there is any other solution for this !!

Thx again and sorry for the trouble

Use AddHandler instead of WithEvents/Handles.

If you're wiring up all the InkOverlay objects to the same handler I'd also set their Name properties in case you need to identify which one has caused the event:

Dim MyInkOverlay(30) As InkOverlay

Dim MyLabel(200) As Label

'....

Sub New()

        InitializeComponent()

        For j As Integer = 1 To 7

            Dim l As Label = DirectCast(Me.Controls("Label" & j.ToString()), Label)

            MyLabel(j) = l

            MyLabel(j).Text = "Y"

            Dim p As Panel = DirectCast(Me.Controls("Panel" & j.ToString()), Panel)

            MyInkOverlay(j) = New InkOverlay(p)

            MyInkOverlay(j).Name = "MyInkOverlay" & j.ToString()

            MyInkOverlay(j).Enabled = True

            AddHandler MyInkOverlay(j).Gesture, AddressOf  InkOverlayGestureHandler)

        Next j   

        ' other code to deal with rest of controls
End Sub

 

Sub InkOverlayGestureHandler(ByVal sender As Object, ByVal e As InkCollectorGestureEventArgs)
    

        Dim candidate As Gesture

        For Each candidate In e.Gestures

            MsgBox(candidate.Id + " " + candidate.Confidence)

        Next

End Sub

Hello, sorry to trouble you all but I'm really new to all this, I'm doing my senior project using vb.net and this is my first time to work with vb.net
So I have to learn it and work with it in a really short time
I'm trying to create an array of labels and connect them to an existing labels in the form as following:

 

Sub New()

        InitializeComponent()

        For j As Integer = 1 To 7

            Dim p As Panel = DirectCast(Me.Controls("Panel" & (j).ToString()), Panel)

            Dim l As Label = DirectCast(Me.Controls("Label" & (j).ToString()), Label)

            MyLabel(j) = l

            MyInkOverlay(j) = New InkOverlay(p)

            MyInkOverlay(j).Enabled = True

            MyLabel(j).Text = "Y"

        Next j

    End Sub

 

I can write it as :

MyLabel(1) = Label1
MyLabel(2) = Label2
MyLabel(3) = Label3
MyLabel(4) = Label4
....
....
but this wont help me couz I have more than 200 labels in my form

how can I solve this????

I tried it and it worked accept for one thing withEvents, 'withEvents' variable cannot be typed as array

 

///

Dim WithEvents myInkOverlay(30) As InkOverlay

///

 

Sub InkOvrlayGestureHandler(ByVal sender As Object, ByVal e As InkCollectorGestureEventArgs) Handles MyInkOverlay.Gesture

       

        Dim candidate As Gesture

        For Each candidate In e.Gestures

            MsgBox(candidate.Id + " " + candidate.Confidence)

        Next

 

    End Sub

what can I do to solve this ??

Hi there , Thanxs alot man

I ll try it now and hopfully I wish it will work :)

If you're using .NET 2.0 or later, then try this:

Dim MyInkOverlay(29) As InkOverlay 'or whatever

For i As Integer = 0 To 29

Dim p As Panel = DirectCast(Me.Controls("Panel" & (i + 1).ToString()), Panel)

MyInkOverlay(i) = New InkOverlay(p)

MyInkOverlay(i).Enabled = True

Next i

If you want to access the array from other methods, then you'll need to declare it at form level rather than as a local variable.
